The present invention relates to a method and device for controlling a drain valve, preferably the descent of the toilet or similar device in a vacuum collector system.

In vacuum sewer systems, vacuum is provided by one or more vacuum pumps, which are also communicated directly with the collecting pipe (drain pipe) from toilets, urinals or similar devices in the system or communicated with the vacuum tank, which is attached with the collecting pipe.

The disadvantage of the well-known vacuum sewer systems is the noise generated when the shutter toilets, i.e. when a drain valve of the corresponding toilet or similar device opens. Especially the peak of the noise is at the beginning of opening the discharge valve and the other peak noise occurs at the moment of closing of the valve. These maximum noise levels occur because of throttling from the outlet of the drain valve.

There are several known methods and devices aimed at reducing noise from toilets and similar devices in vacuum sewer systems. Incidentally, it is well known the use of airtight or noise-attenuating free covers, as well as the use of artificial air flow in conjunction with drain valve. Butsuch methods and devices to reduce the noise is very minimal i.e. 1-3 dB.

Closest to the claimed method is a method of control drain valve, preferably the descent of the toilet or similar device in the vacuum manifold system, including opening and closing the drain valve (see U.S. patent No. 5007117, E 03 D 11/00, 1991). When implementing this method, a drain valve open and close with speed, providing the time of opening and closing about 0.6 seconds.

Closest to the claimed device is a device for controlling a drain valve, preferably the descent of the toilet or similar device in a vacuum collector system, where the device and flush valve are driven by the vacuum created in the manifold system, where the device includes at least three working valve (U.S. patent No. 5317763, E 03 D 9/14, 1994).

Suddenly when checking the descent of vacuum toilets inventor found that the noise can be substantially reduced by reducing the opening time and closing a discharge valve. In accordance with the invention, the inventor has come to the way of the drain control valve, preferably the descent of the toilet or similar device in the vacuum manifold system, including opening and closing a discharge valve with a device to control, characterized in that the trigge is Noah valve opening and closing speed, providing the time of opening and closing, respectively, 0.25 and 0.4 seconds.

Further, the inventor has come to create devices to control drain valve, preferably the descent of the toilet or similar device in a vacuum collector system, where the device and drain valve are driven by the vacuum created in the manifold system includes at least three working valve. These workers valves have the opportunity to return to its original state by means of a common piston rod in the form of a Cam, which is driven by a piston in the cylindrical chamber, whereby the first valve, actuated starting device, according cylindrical chamber with a source of vacuum of the second valve, actuated by the Cam and connecting the source of vacuum in the main pipe with a driving device, a discharge valve and a third valve connects the discharge ring or similar device with a source of water through pipes and channels.

Independent claims 1 and 2 of the claims define the basic essential features of the invention.

In addition, the claimed device is also characterized by the fact that the three valve are each in the form of a stabilizer with a movable arm that is spring-loaded by a spring and one end is connected with the elastic body Klah is Ana, designed with the possibility of a snug fit to the valve seat for holes located on one or both sides of the valve body and the other end of the rocker arm has the ability to move under the influence of the starting device or Cam projections on the Cam for closing or changes passing through the valve flow.

The control device may be provided with a fourth working valve, designed for rapid evacuation of the respective air outlet in the driving device for a discharge valve, while the fourth valve is controlled by a second valve. The fourth valve is made in the form of a rocker arm which is mounted for displacement cylinder-and-piston mechanism, a piston which is spring-loaded by a spring to hold one end of the rocker arm in the lower position, causing the valve body at the other end tightly against the upper valve seat in the original position and can be moved by the piston until it stops at the bottom of the saddle under the control of the second valve. The starting device may be made in the form of a latch which is spring-loaded by a spring and can operate the button through the wire, when this latch is set to compress the valve rocker valve in the initial position by the spring, and the valve body closes the valve seat opening vacuumn the second tank, moreover, the latch releases the rocker, when his release from the locking position, thus the valve body opens the valve seat and closes the valve seat. The latch is returned to its original position when the Cam is in its upper position and presses on the valve rocker arm, returning it to its original position.

The invention will be further described by examples with reference to the drawings.

Figure 1 shows a chart of noise level versus time for opening and closing a discharge valve in the toilet, where the method in accordance with the invention and improvement of the method is compared with the known solution.

Figure 2-4 shows three successive positions of lavatory with drain valve, drain water, and a work device in accordance with the invention.

Figure 5 to 7 show three successive positions of the same devices as in figure 2-4, but with an alternative switch and additional work valve drain valve.

As noted above, the noise level reaches a peak when a drain valve in the toilet with vacuum collector system respectively open and close. The maximum noise level occurs in the check valve opening when the valve body or the closing part of the valve are on the way up or down, and forms shall be larousee carrying the valve hole. Passing through the narrow opening of the fluid (air) creates noise when reaching a certain speed. The water in the toilet tank as the air trapped in the system, represent the mass, which expires with acceleration when opening the valve. In principle, the valve should open with the speed at which it is fully open (no obstacles to the flow before the air reaches the speed at which you will have noise. Figure 1 shows the noise level in decibels as a function of time known control device, shown by the dotted line a, and the noise level for the method of control in accordance with the invention, shown by a continuous line C. the Continuous line shows the improvement that will be commented at the end of the description. As can be seen from figure 1, the noise increases when the drain valve is opened until it reaches the upper point (I), when the throttle valve is at maximum. After that, the noise is reduced and aligned (II)when the valve is fully open, and then increases when the valve is closed before reaching a second peak (III)when the throttle valve is again maximal. Studying the two curves a and b In the diagram in figure 1 you can see that the time of opening as well as closing time for a discharge valve according to the control method with the availa able scientific C with the invention is significantly less than in the known solution. More precisely, the time of opening and closing according to the invention are respectively 0.25 and 0.4 sec, whereas the time of opening and closing of the known solutions is 0.6 to 0.8 and 0.6 and 1.3, respectively. The noise is also much lower, close to 15 dB.

According to the present invention it was found that the noise in the vacuum manifold system, which makes use of a drain valve in the toilet or similar device, can be reduced to a large extent by reducing the time of the opening and closing of the drain valve. Tests have shown that a drain valve in the well-known vacuum manifold systems operates at the time of opening of 0.6 to 1 and at time of closing from 0.6 to 1.6 C. Any reduction of the time of opening and closing a discharge valve in such systems below 0.6 gives the noise reduction in the drain valve.

The question whether it is possible to achieve a time of opening and closing below these values will depend on whether the speed of the discharge valve as well as the working mechanism of this valve. The inventor has previously developed such a quick drain valve, which is described in Norwegian patent application No. 943535 and which is shown in Fig.2-7 (not further described).

The present invention also relates to the operating or control device for a discharge valve which is combined with the previously patented blowoff valve, capable of opening and closing a discharge valve for a time of 0.25 and 0.4 seconds, respectively. This control device will be described hereinafter with reference to figure 2-4.

The figures depicted toilet 1 with drain ring 2 mounted therein, a drain valve 3, is placed in the outlet pipe 4 of the toilet, and the operating or control device 5 in accordance with the invention, shown respectively in the frontal and lateral projections.

Because the components in figure 2-4 the same and only detectable difference sequences on the functioning of the invention, reference is initially referred to figure 2, which describes the design of the control device 5. The control device consists of an upper cylinder 6 with a moving piston 7 and the bottom of the valve chest 8 with three different working valves, the first valve 9, the second valve 10 and the third valve 11, in addition to the stock in the form of a Cam mechanism 12. The valves 9, 10 and 11 of the same type in the form of a beam, where the rocker arms 36, 37 and 38, respectively, are biased by spring 13 and the body 14 of the valve on the opposite side of the rocker arm abuts against the valve seat (hole) 15, 16, 17, 18, 19 in the respective valve chambers 62 for valves 9, 10 and 11.

The piston 7 is spring-loaded by a spring 20 and is in the lower position, when the control device and the exhaust valve are in the initial closed position, as shown in figure 2. In this position the valve hole 17 for operating the valve 10 is closed, while the valve hole 18 is opened and communicated with the atmosphere through a pipe 21.

Starting device 23 connected to the arm 37 in the valve 10 to see an enlarged cross-section of the starting device 23 under the toilet in figure 2-4. This device includes a latch 39 which is biased by spring 40 and holds the rocker 37 under the pressure of the spring 13.

Pressing the trigger button 22 on the starting device of the traction cable 24 when the movement pulls the latch 39 ago, so that the arm 37 of the valve 10 opens the valve hole 17 and closes the valve hole 18. As a result, the air passes from the chamber 41 of the cylinder above the piston 7 through the pipe 21, through valve 10 and then through the pipe 25 and the vacuum tank 26 to the drain pipe 27 under vacuum, as shown in figure 3, the piston 7 will now move to the top position.

As a result, the protrusion 28 on the Cam mechanism 12 moves the arm 36 in the valve 9 so that the valve closes the outlet 16 into the atmosphere and opens the exhaust from the piston chamber 29 drain valve 3 through the piping 16, 25 and further to the tank 26. Thus, the valve 3 is opened for emptying the contents of the toilet tank. Before installing the valve 9 by means of a Cam in the stupa 28, the Cam protrusion sets the valve 11 by the rotation of the rocker arm of the valve body 14 from the valve hole 19, so that the water will expire through the valve 11 from the tank with water (not shown) through the pipes 33, 34 and drain ring 2 for the descent of the toilet 1.

When the piston 7 reaches the upper dead point in the cylinder 6, the Cam protrusion 35 acts on the rocker arm in the valve 10, whereby the valve is returned to its original position and is opened for admission of air from the atmosphere through the pipe 21. Simultaneously, the starting device 23 is returned to its original position, thus operating the device is ready for a new descent of the toilet. The piston 7 will now test the effect of the spring 20, returning to the initial position, as shown in figure 4, and the Cam mechanism is in its return movement to first return to the initial position of the valve 9, so that air from the atmosphere will pass through the valve hole 16 through conduit 61 into the cylinder 29 and a discharge valve 3, so that it closes, and then the Cam mechanism will restore the position of the valve 11, so that it will block water flow to the toilet. The control device is in its initial position standby, ready for a new operation.

The speed of the piston 7 in the chamber 6 of the working device against the force of spring 20, is riding the from how fast the air is flowing from the respective source into the cylindrical chamber 41. This evacuation/air flow can be metered in a throttling device (not shown)associated with the valve 10.

In the preferred embodiment of the invention, as shown in figure 5-7, time of opening and closing a discharge valve is additionally reduced through the use of an additional fourth operating valve 42 is preferably placed on top of a discharge valve 3, which is now “torn” from the toilet and shows out of it. The main purpose of the fourth valve 42 to provide for quick release, respectively, the evacuation of air from the cylinder 29 and a discharge valve 3 and consequently faster to complete opening and closing the drain valve. Working the valves 9, 10 and 11 are the same as in the previous example, but instead of connecting directly with the cylinder 29 drain valve 3 line connection 61 from the valve 9 is now connected to the device, the piston/cylinder 43/44 in the fourth operating valve 42. The piston 43, which is held in the lower initial position by the spring 46 moves the rocker 45 and, accordingly, the valve body 47 at the opposite end of the rocker arm from the upper position where it abuts against the valve seat 48 (exit valve in the vacuum tank 26 in the lower position, where it rests in Sedl the valve 49 (message between the atmosphere and the cylinder 29 drain valve).

Figure 5-7 also shows another embodiment of the starter 50. The starting device includes in this example, the button 51 with a piston 52, a spring-loaded by a spring 53, which is located in the cylinder 54. Cylindrical chamber 56 this unit filled with fluid, preferably air, which is designed for start-up valve 10 trigger 57, 58. Jet 59 (not shown) controls the return fluid in the cylinder 56, holding a short time discharge mechanism 57, 58, and therefore it is possible to obtain a sufficient opening time for the working of the valve 10.

The work of the construction shown in figure 5-7, will be described as follows. Figure 5 shows the original position, where the valve 3 is in the closed position. Pressing the button 51, the liquid in the cylinder 56 through the pipe 55 is fed to the trigger valve 10, having a form cylinder device 57, 58, respectively. The piston 57 will now move the balancer and accordingly, the body 14 of the valve 10 from left to right, that is where it closes the opening 18 and an opening 17, as shown in Fig.6. Now the air will flow from the cylinder 41 through line 25 into the vacuum tank 26. The piston 7 with the Cam 28 is now moving forward, balance, and accordingly, the body 14 of the valve 9 is moved from left to right, an opening 15 and closes on the opening 16. The Cam includes a valve descent of water 11 (described with reference to figure 2-5 and therefore will not be described further).

As soon as the body 14 of the valve 9 opens the valve hole 15, the air in the cylinder 44 of the fourth working valve 42 will be released through the pipe 61, a working valve 9 and into the vacuum tank 26 through line 16 and 25. The piston valve 42 is now moving forward and accordingly the rocker arm 45 as well as the body of the valve 47 closes the hole 49 and opens the valve hole 48. The air is quickly released from the cylinder 29 drain valve directly into the vacuum tank 26 through conduit 60, and the piston 64 and accordingly the body 63 of the discharge valve 3 is rapidly moving forward in its open position, and the toilet will now be launched. Quick release air from the cylinder 29 and a discharge valve is provided by the use of this valve, as it applied to large valve openings, larger diameter pipes and a shorter distance between the cylinder 29 and the reservoir 26 (less resistance to flow.

As soon as the piston 52 when the button 51 of the starter returns to its original starting position, the valve 10 will return to its initial position, closing the valve hole 18, and opens the valve hole 17. This provides a flow of air from the atmosphere through the opening 17 in the Cam is ru 41 of the control valve 5, as the piston 7 with the Cam control device 12 will move downward, as shown in Fig.7 (final cycle). Now, when the Cam 12 moves down, working the valve 9 will return to its original position, will close the valve hole 15 and opens the valve hole 16. This will ensure the flow of air from the atmosphere through the valve hole 16 in the valve 9, then through the pipe 26 into the cylinder 44, the valve 42 will restore its position, closing the opening 48 and opening 49 to supply air into the cylindrical chamber 29 drain valve 3 from the atmosphere. The piston 64 a discharge valve 3 will now move down, closing the drain valve. The controller and valve are now in the initial position for a new cycle.

Curve C in Figure 1 shows the improvement of the noise level with an additional fourth working valve 42. As you can see from this graph, the peak noise levels I and III significantly reduced due to the fact that the time of opening and closing a discharge valve is reduced. So, with the fourth working valve noise has been reduced by an additional 6-7 dB.
