The invention relates to control systems for shut-off vacuum valve, designed for vacuum sewer systems, comprising a housing with an outer wall located in the first valve, switchable dynamic pressure created by the accumulated waste water from the first to the second position; limited to the first membrane, the first camera with adjustable pressure through the first valve, the first membrane is functionally connected with the second valve through which, depending on its position, the negative pressure or the atmospheric pressure is fed to the valve; a first connection through which the first camera can be connected with a vacuum source and which, when missing or too small the dynamic pressure is blocked by the first valve being in its first position, and when a sufficient dynamic pressure open the first valve being in its second position; leading to atmospheric pressure, is connected to the first chamber, preferably having an adjustable cross-section of a second connection, and when loaded with a sufficient negative pressure to the first chamber of the first membrane with a second valve can be switched from the first position connecting the valve to atmospheric pressure, a second position connecting the shut-off klapas exhaustion while the first valve is in its second position, opening a first connection between the vacuum source and the first camera overlaps the second connection leading to the first chamber and the load of atmospheric pressure.

To keep clean the reservoirs, it is necessary that water got into treatment plants. Often it is, however, impossible due to the disproportionately high costs of traditional sewer system or due to difficult local conditions, such as lack of natural inclination, low population density, adverse soil or crossing the water protection zone. But even for such problematic cases there is the possibility to produce discharge of waste water treatment plants when applied to the drain of underpressure or vacuum Sewerage".

The corresponding vacuum sewer system includes as the main component parts of the local distribution of wells with working without electricity system control and shut-off or shut-off valves connected to the piping system with orderly arranged high and low points, and vacuum station with collapsible tanks for waste water, sewage pumps, vacuum pumps, measuring and regulating devices.

For the transportation of waste water it is first flows under free-head of the buildings on the usual house piping to the sump, located, for example, on the boundary of the well, which are exclusively pneumatically controlled shut-off valves and the corresponding control system. With a sump connected embodying air gauging tube, while a prisoner in her air hydrostatically compressed accumulated in the sump fluid, so that a dynamic pressure.

Using the system control mechanism, given the dynamic pressure shut-off valve is opened and water is sucked into the vacuum pipeline. The valve closes depending on time after a few seconds, the force of the spring and vacuum.

Itself of waste water accumulates in low points in the piping system and gradually moves additionally, the incoming air in the direction of the vacuum station. Then the waste water from the collecting tank of the vacuum station conventional sewage pumps, pressure pipe and tubing with a free pressure is pumped to a water treatment facility. In a retention tank and in the pipe system, the vacuum is maintained by a vacuum generator, such as a vacuum pump.

Designed for shut-off valve control system must provide the ability to automatically adapt to subject the suction porcentajes water and operating conditions (for example, the power available rarefaction) in the drainage system.

The control system is known from DE-C-43 36 020, is extremely compact and structurally simple and has a high operational reliability. Thus there is practically independent of the level of available vacuum synchronized control, i.e., after the disappearance of the dynamic pressure if the liquid is sucked away, the control system closes the supply of vacuum to the shut-off valve after a preset period of time and shut-off valve is purged with ambient air, so that the shutoff valve is closed. Remaining after the extraction period of time before closing shut-off valve is required for inlet conveying air from the environment into the system vacuum. For operation of the system it would be desirable that the ratio of the volume of intake air and the intake of fluid was greater than the weaker of the available vacuum. The above-mentioned control device is distinguished, in particular, also the fact that he has time after opening required air inlet, remains approximately constant, and the volume of the sucked portion of the waste water becomes the smaller, the weaker the existing vacuum. Another advantage of this control device is to affect dramatically changing the state from the management so to the second Kapan, managing the connection with shut-off valve, could dramatically switch.

In addition, US-A-4373838 known control system, offered under the name "AIRVAC". In order for this system to get the opportunity synchronized control through the camera with adjustable pressure required hose of small diameter, which can easily be blocked, so that functionality is not always guaranteed, in particular, is not achieved when summed from the environment the air is dirty or wet. Also there is no one open/closed valve position, the transmitting vacuum to the shutoff valve. This means that with a weak vacuum can occur vibration shut-off valve. Also, do not specify clearly the amount of waste water or the mixture of waste water and air on one step of opening the shutoff valve. This may, in particular, when a large flow of waste water to cause functional impairment. In addition, the disadvantage is that the time sucking unfavorable for the entire system depends on the available dilution, as periods of time of discovery, for its part, depend on the available dilution. Thus, the opening at the small vacuum shorter than in a strong vacuum. Because of this, in private the tee, at low pressure and large accumulated in the sumps quantities of water there is a danger that the pipeline network will be flooded and thus will no longer function properly, because when a flooded system power vacuum continues to decline.

The drawback is that the opening of the second valve, opening the access of vacuum to the shut-off valve, can occur even at low pressure, which, however, is not always enough for a quick extraction. Because this increases the risk that waste water will be raised in the low-temperature region of the pipeline, and there may freeze.

From DE-A-3727661 known pneumatic control device for shut-off valve on the vacuum pipe for the waste water. To ensure accurate control and reliable operation of the control device, along with the first valve is controlled by the dynamic pressure, and structurally expensive device synchronized control requires at least one distribution valve and one valve minimum pressure.

The control system of the above kind is described in EP-A-1091053, she has a simple structure and ensures the impossibility of penetration of the liquid into the chamber and fill the vacuum.

Other systems driven by what I managed to vacuum shut-off valve described, for example, in EP-A-0649946, DE-A-10026843, DE-U-29616003 or DE-B-10 2006028732.

The present of the invention is to improve the management system of the aforementioned kind so that when more simplified compared with the known control systems, the design provides high reliability. At the same time should be provided to the impossibility of penetration or, respectively, the concentrations in the control system of the liquid, which affects the functional reliability. In another aspect it should be possible to modify the simple way to turn the valves and, thus, shut-off valve, so that the inclusion could occur when the desired dynamic pressure. Also, if necessary, it should be possible to manually switch the control system used to control the shut-off valve.

To solve this problem essentially provides that the first valve contains the starting membrane, through which may overlap the first connection in the first position of the first valve, and a second membrane, which is connected via an intermediate element with a starting membrane and through which may overlap the second connection in the second position of the first valve, and the intermediate space between the starting membrane and the second membrane mo which should be loaded by the dynamic pressure.

In General, the subject invention is a control system for isolating the vacuum Kapan designed for vacuum sewer systems and including the first valve and the second valve, depending on the position of which is controlled shut-off valve through which the accumulated water can be otkazyvatsa through the sewer system. For switching the first valve functionally connected with the second valve has created the accumulated waste water dynamic pressure, which loads the intermediate space between the starting membrane and the membrane of the dynamic pressure, forming a single node and the first valve.

In contrast to previously known constructions, the two forming one node of the membrane, namely the starting membrane and the second membrane, which can also be called the membrane of the dynamic pressure, to form a first valve through which, depending on established between the membranes of the dynamic pressure, the first chamber is loaded with vacuum or atmospheric pressure so that the second valve, which may be termed a valve, which allows the connection between the inlet vacuum piping and shut-off valve or overlap.

Essential for the invention constructive recognized which provides, what is the starting membrane, depending on its position, closes or opens the second chamber, which is located in the flow path between the vacuum source and the first chamber in the first connection and which is in the first position of the first valve connected to the vacuum source. For adjustment of the switching process, depending on the steady-state dynamic pressure according to the invention provides that the loading pressure acting on the starting membrane surface of the second camera can be adjusted by means of an element that is managed outside through the body.

In particular, it is provided that the second camera from the starting membrane has a circular bottom surface, which is limited perimeter sealing element, such as a round ring, and this sealing element acts are accessible from outside the housing mounting element intended for permutations of the sealing element. If, for example, the surface of the second chamber decreases, it is possible to detach the starting membrane seal and, thereby, moving the first valve at a lower dynamic pressure, more than the bottom surface of the second chamber.

Preferably, the adjusting element is located for movement in the channel opening, such as drilling, is AutoRAE the outer side of the can tightly closed. To allow certain changes in drilling can be entered pin elements of a certain length. However, there is also the possibility of using the item a screw-in drilling through a kind of screw to change the surface and fill the vacuum through the second chamber.

Starting membrane has a wavy geometry of the seal, which has a ring, U-shaped in cross section peripheral external plot, and even, in the form of flat seals internal area that can fit to the seal that restricts the second chamber.

Starting membrane may also be characterized by the fact that she was in his position, sealing the second chamber, in cross section has a U-shaped or made in the form of a double U geometry, preferably with the district L-shaped edge, whereby the starting membrane can be fixed in the first intermediate wall of the housing. The result is a geometry having the form of a glass with a convex outward peripheral wall.

From the lower wall of the starting membrane, called flat seal that goes around the center connected with the second intermediate membrane element intended for common permutations. For secure fastening it provides that the Central region is t inner side of the lower wall of leaves provided with a through hole inner ledge, which hermetically permeated preferably having the form of a trunnion pin element and connected to the first mount, which moves the second membrane.

In particular, it is provided that the second membrane moves away from the first plate mounting, which by means of an intermediate or, respectively, the pin element is connected with the starting membrane.

Limiting the first chamber, the first diaphragm should, in addition, also depart from mount called the second bracket, passing through the first chamber of the spring element is loaded by a force in the direction of the second intermediate wall, which is away from the first valve and through which passes the valve of the second valve.

The first membrane and is penetrated by the valve, a second intermediate wall limit third chamber which is connected to the inlet leading to the atmosphere. The spool extending from the enclosing first and second membrane attachment, creates, thus, depending on the position of the second valve, the connection between the third chamber and the fourth chamber, through which the second valve can be closed relative to the supply of vacuum or to connect with him. From the fourth camera moves also supply to shut-off valve.

When closed, the second valve through the vacuum supply RA is warning enters the second chamber, closed starting membrane is in the first position of the first valve. The first camera and the third camera is loaded with atmospheric pressure. Atmospheric pressure is also turned on starting from the membrane side of the second membrane, which restricts the fifth chamber closed from the outer side wall of the housing. The connection between the inlet of the atmosphere and the fifth camera is passing through the wall of the body channel, the atmosphere passes through the filter, connecting the fifth camera channels.

The fifth chamber is connected via a channel, also held in the housing wall, with the first camera. This camera is also connected through a channel penetrating the first intermediate wall, with the space, passing between the outer side of the starting membrane and the first intermediate wall.

If in the intermediate space between the starting membrane and the second membrane is installed with sufficient dynamic pressure, the starting membrane to the second membrane is moved to restrict the second chamber to the seal so that the vacuum could be transferred into the first chamber. Simultaneously with the second membrane closes the connecting channel between the fifth chamber and the first chamber. By reducing pressure in the first chamber while simultaneously continuing nehruji the AI atmospheric pressure in the first diaphragm facing away from the first chamber side, as well as using interchangeable in the fourth chamber of the valve plate of the second valve, which also operates the atmospheric pressure, but which, however, has a smaller surface than the first membrane loaded with effective pressure surface of the second attachment can be overcome the spring force applied by the spring to the first membrane or, respectively, its mounting, so that the second valve is moved, i.e., opens. Simultaneously through the valve is blocked, the connection between the third and fourth chambers, so now through the open second valve vacuum can get to the shutoff valve and, thus, turns it, since the valve plate closes the loaded first vacuum connection between the vacuum source and the first chamber while simultaneously loading the first chamber with the atmospheric pressure.

After the desired reduction of the dynamic pressure node of the starting membrane, a second membrane, which constitutes the first valve falls into its basic position and the seals the second chamber relative to the first chamber, so that its further loading of the vacuum does not occur. The vacuum itself is now reduced due to the more private second membrane channel, which connects the fifth camera is connected to the second atmospheric pressure, with the first camera. Due to this, the spring force can act on the first membrane or, respectively, its mount so that the second valve goes. At the same time, the atmospheric pressure is passed through is no longer blocked by the valve channel in the second intermediate wall to the flue from the fourth chamber inlet shut-off valve so that it actuates and closes.

In an improved embodiment of the invention provides that the valve in the axial direction provided with Pro valve plate ledge, whereby through a sealed opening in the housing is possible axial shifting of the valve when closed, the second valve, which makes it possible manual operation of the control system, thereby switching the shut-off valve.

In addition, the proposed invention the control system differs from the previously known constructions the fact that through the carts for the vacuum connected to the housing via a connecting pipe, shut-off valve and the atmosphere in the working position of the control system is oriented vertically, and United with them, the camera is focused on connecting pipes in such a manner that it can be accumulated liquid or condensate can CTE is the substance under the action of gravity. This applies at least third and fourth chambers.

In Fig.1-6 shows images of longitudinal sections of the proposed invention the control system 10, which takes place the it control shut-off valve, designed for vacuum sewer systems.

Working without electricity, however, using Pneumatics, also called a universal control system, the control system 10 includes a stepped cylindrical housing 12, provided with a peripheral wall 14 and end walls 16, 18. In Fig.1 shows a control system 10 in its embedded position, so that the fittings or connecting pipes 20, 22, 24 are oriented vertically downwards. The connecting pipe 20, which takes place in the area shown on the right in the drawing, the end wall 18, is connected to the vacuum source of the vacuum sewer system. Vacuum hereinafter also referred to as vacuum.

Adjacent pipe 22 leads to a shut-off valve, and passing in the area of the left end wall 16 of the pipe 24 connects with the atmospheric pressure. In addition, there is a supply 26, which is connected with the national team capacity, which creates a dynamic pressure depending on the accumulated and subject to suction the waste water. The value of dynamic pressure determines the actuation of shut-off valve as described below.

The housing 12 has a first intermediate wall 28, which in the drawing is located near the left end wall 16, and a second intermediate wall 30, which passes between the first intermediate wall 2 and the right end wall 18.

The primary components of the control system 10 are called the first valve starting valve 32 and the second valve 34, which is the valve through which may be created or overlap the connection between the inlet 20 of the vacuum and inlet 22 for a shutoff valve, and depending on the dynamic pressure.

Starting valve 32 consists of the starting membrane 36 and the second membrane 38 to provide unidirectional movement are connected to each other connecting or intermediate element 40.

When closed, the starting valve 32 of the lower section 42 of the starting membrane 36 closes the second chamber 44, which is connected with the connecting pipe 20 of the vacuum through the channel 46, passing the first intermediate wall 28 of the circumferential wall 14 and right end wall 18. This channel 46, which in these figures consists of sections 45, 47, 49, with closed control valve 34 is closed by means attached to the seat 48 of the valve plate 50 distribution valve 34 relative to the camera 64, called the fourth chamber, from which depart the fittings 20, 22 for vacuum or, respectively, the shut-off valve. When closed, the second chamber 44 of the lower portion 42 adjacent to the district seal 86, such as a circular ring, which restricts the which the chamber 44 on the periphery.

The intermediate space 52 between the starting membrane 36 and the second membrane 38 is connected to the inlet 26, which is loaded by the dynamic pressure.

Also called the membrane of the dynamic pressure of the second membrane 38, which departs from the plate of the first mounting 54, by means of the coupling element 56 is connected with the starting membrane 36, which thus forms a supporting element 40 or, respectively, is part of it. For a reliable connection at the starting membrane 36 with the inner side there is a cylindrical protrusion 58, provided with a through hole, through which hermetically passes statourty connecting element 56 and fixed with extension 60 having at one end a shape of a truncated cone. The opposite end stiptease the coupling element 56 is adjacent to the outer side 62 of the plate of the first mounting 54 of the second membrane 38 and is made in the form, resembling the head of the screw.

Starting membrane 36 has the form of a kind of undulating seal, which has a ring, U-shaped in cross-section of the peripheral area, recorded in the first intermediate wall 28. Hermetically closing the second chamber 44 of the lower portion 42 acts as a flat seal.

On the opposite regarding starting Kapan 32 side of the first intermediate article is NCI 28 has a chamber 72, called the first chamber, which is closed on one side of the intermediate wall 28, and on the other side of the membrane 74, called the first membrane, which moves away from the second mounting 76. On the second bracket 76 operates the spring element 75, based on the first intermediate wall 28 or radiating area, so that the second bracket 76 is loaded with a force in the direction of the second intermediate wall 30.

From the second mounting 76 moves the spool 78 distribution valve 34, which passes through the second intermediate wall 30.

When closed, the starting valve 32 (Fig.1, 2) atmospheric pressure enters through inlet 24, the channel 66 into the chamber 90, called the fifth camera, which on the one hand is limited to the outer side of the second membrane 38 or, respectively, the first bracket 54, and on the other side of the end wall 16 or neighboring wall. Between the channel 66 and the fifth chamber 90 includes a filter 92. From the fifth chamber 90 departs preferably passing diametrically fitting 24 and parallel to the end wall 16 different channel 94, which is relatively wavy boundary region of the second membrane 38 is arranged in such a way that the channel 94 in the closed starting valve 32 transmits the stream, and when you open the starting valve 32 closed. After passing from the wall 12 of the housing sections 96, 98 of the channel and to allow ZAZ is R 100, used for synchronized switching valves 34, the first chamber 72 when the outdoor channel 94 may be loaded by the atmospheric pressure when starting valve 32 is closed. The first chamber 72 through the channel 102 is connected to the space between the outer side of the starting membrane 36 and the first intermediate wall 28. This area, which when closed, the starting valve 32 forms an annular space, indicated by the position 104.

In addition, the atmospheric pressure through the connecting pipe 24 is installed in the third chamber 82, passing between the second bracket 76, on which rests a spring 75, and the second intermediate wall 30. After passing in the longitudinal direction of the spool 78 of the longitudinal slot 84 in a closed control valve 34, the atmospheric pressure can be transmitted to the fourth chamber 64 from which departs the fitting 22 connected with shut-off valve. Therefore, shut-off valve is set to the atmospheric pressure, resulting in it is closed.

If in the intermediate space 52 between the starting membrane 36 and the second membrane 38 is the dynamic pressure of such magnitude that established in the second chamber 44, the vacuum pulls the starting membrane 36 and, thereby, makes her the lower portion 42 adjacent to the seal 86, and the fact itself is m, overcome created by the vacuum holding force, the second membrane or membrane 38 dynamic head/pad membrane 36 moves to the left (Fig.3), resulting, on the one hand, the channel 94, which can also be called a ventilation channel is closed by the second diaphragm 38, and on the other hand, established in the second chamber 44, the pressure is passed through the slot or gap 120, passing the first intermediate wall 28 from the side of the membrane, the channel 102 into the first chamber 72, so that the atmospheric pressure is sucked away. Because of this, due to the atmospheric pressure prevailing in the third chamber 82, which is limited to the first membrane 74 and the second bracket 76 on the one hand, and the second intermediate wall 30, on the other hand, operating on the second carrier 76 the force of the spring 75 can be overcome, resulting in the control valve 34 is opened as the valve 78 is connected with the second bracket 76. Thus, the valve plate 50 may his seal 124 to detach from the seat 48 of the valve, so fill the vacuum channel 46, leading to the fourth camera will no longer closed, so that the connecting pipe 22 shutoff valve is loaded by vacuum. When moving the slide valve 78 are closed simultaneously existing in the longitudinal direction in eg the circumferential wall of the longitudinal slot 84, so the fourth chamber 64 can no longer be loaded by the atmospheric pressure.

Switching valves 34 is regardless of the fact that as the valve plate 50 and the first membrane 74 and the bracket 76 (2nd attachment) are impacted by the atmospheric pressure, since the surface distribution of the membrane 74 with an effective surface mount 76 is greater than the surface of the valve plate 50.

The choice of dimensions of the surfaces and effort of the spring is made so that the absolute pressure in the first chamber 72 should be approximately of 0.21 to 0.24 bar, to allow switching valves 34.

Once after opening the shut-off valve dynamic pressure in the intermediate space 52, called the chamber of the dynamic pressure will decrease shown in the drawing starting valve 34 will be moved due to pre-tension the starting membrane 36 to the right, so that the second chamber 44 will be closed with airtight junction of the bottom surface 42 of the starting membrane 36 to seal 86 that surrounds on the periphery of the second chamber, so that the connection with the atmosphere no longer, because leading to the first chamber gap 120 in the first intermediate wall 28 passes out of the second chamber 44. At the same time by moving the second member the s 38, i.e., its peripheral thickening, opens the channel 94, so the atmosphere through the channels 96, 98 and allow the gap 100 can be transmitted into the first chamber 72.

Due to the above process, it becomes apparent that the starting membrane 36 and the second membrane 38 perform the function of the valve.

Cross-section of the nozzle gap 100 can be varied by rotation of the screw 142, so it can be adjusted duration, with which the first camera is loaded with atmospheric pressure. Now with both sides of the first membrane 74 or, respectively, its mount 76 is established the same pressure, the spring 75 can move the second carrier 76 in the direction of the second intermediate wall 30 and, thereby, the spool 78 distribution valve 34 so that the control valve 34 is closed, that is, the seal 124 of valve plate 50 adjacent to the seat 48 of the valve. At this point, is connected to the vacuum channel 46 is blocked relative to the fourth chamber 64. At the same time through the existing district wall of the spool 78 of the longitudinal slot 84 atmospheric pressure can be transmitted to the fourth chamber, resulting in, respectively, through the connecting pipe 22 is loaded shut-off valve so that it closes.

As follows from Fig.6, there is also the possibility to open houses is adelically valve 34 without creating the necessary dynamic pressure in the intermediate space 52 between the starting membrane 36 and the second membrane 38. For this purpose, the valve 78 moves the speaker asked for the valve plate 50, the plane of the ledge 160, which is focused on hole 162 in the end wall 18, the opening 162 is sealed by a flexible element, such as a rubber element 164. Through element 164 may thus act on the spool valve 78 axial forces on its sequel (the ledge 160), resulting in the spool valve 78 is moved into the housing 12 to open the control valve 34. Upon termination of the axial force on the spool 78 becomes a tangible force of the coil spring 75, resulting through the second mounting the spool 76 78 moves back into its original position to close the valves 34.

The essential feature of the control system 10 according to the invention is constructive possibility of effective regulation of the current in the starting membrane surface 36 of the second chamber 44 so that the start system 10 control was carried out with the desired dynamic pressure. For this purpose there is the possibility to move the seal 86, such as a circular ring, bounding the second chamber 44 on the periphery. This can be carried out in accordance with Fig.6 by being inserted into the housing mounting elements, such as pins 200, with which the s seal 86 in some areas more or less pressed inside (area 87). The installation elements 200 may have a desired length and inserted into nesobrannyj the channel housing 12, which on the outside is sealed.

Instead of inserting pins of different lengths in the channel can also be screwed threaded pin, so that it becomes possible permutation-type adjustment screw.

In Fig.7 shows also that the section 49 of the channel flows into the second chamber 44 through the opening 202 through which the camera 44 may be loaded by vacuum.
