Water distributor

FIELD: transport, distribution.

SUBSTANCE: invention relates to water distributor to be used for water supply for garden waste sprayers. Water distributor incorporates the fluid-pressure-activated stepwise water feed regulator. The latter allows stepwise switching to several angular increments (IW) and, hence, passage of inactive outlets (A5, A6) of said water distributor. Outlets (A3-A6) may be designated by the user as active or inactive. Stepwise switching device sets the distributor body to different preset step magnitudes, hence, to the other water discharge outlet. Different step magnitudes are set by variable stroke (D1-D5) of piston (KO) of stepwise regulator.

EFFECT: ruled pressure drop at active outlets, simplified servicing.

The invention relates to a water distribution device.

Adjustable on-time supply numerous garden irrigation systems such as sprinkler rectangular or circular operation, the installation of drip irrigation or root irrigation, and other similar, is, as you know, with the programmable computer-irrigation in combination with the water distribution devices. Water distribution device through the inlet of the accession connected with outlet attach a computer-irrigation and contains, in turn, numerous outlets with the corresponding tap connection. The distributor housing is mounted rotatably in the casing of a water distribution device and, depending on the position of the turn, connects one of the tap outputs to a common inlet connection, while the other outputs respectively clipped. The device phased switching signal phasing hydraulic switching the computer-irrigation, switches the distributor body further to the next exit. The signal phasing hydraulic switching the computer-irrigation contains a change of pressure at the common inlet connection, in particular a temporary water shut-off the computer-irrigation. In a typical execution� device phased switch contains the spindle with the guide spiral, moving in the direction of the spiral axis, depending on the water pressure against a return spring, the piston, which carries with it the distributor housing when rotated around the helical axis, and the freewheel clutch. The principle of operation of such known water-distribution devices are well-known.

Often, not all of the available outputs of the water distribution device is demanded to supply irrigation systems. Such exits are marked as inactive and Vice versa, is designated as the active outputs that are connected to water supply irrigation machine. Inactive outputs can be trimmed individually, downstream of the distributor housing. Gradual switching of the distributor housing from one of the existing exit to the next exit is via water shutoff the computer-irrigation and reducing water pressure in the water distribution device. The pressure reduction on the active exits through a water drain connected to the irrigation installation is fast, however, this feature of pressure reduction is limited in places where the current output is a clipped output inactive. Consequently, all the outputs are typically connected by narrow drainage pipes, which when clipped inactive�moves after the termination of the water reduce the pressure on the active outputs. For sufficient reduction of water pressure is required to withstand relatively long time of cutoff of the supply of water, typically 30 to 60 seconds.

Through drainage pipes pressurised water distribution device is loaded with water equally as valid outputs, and other active outputs, which can lead to uncontrolled excessive irrigation, particularly when it comes to irrigation systems with a minor flow of fluid, for example a drip.

The object of the present invention is to improve the water distribution device with phased cyclical switching of the distributor housing by varying the pressure.

The invention described in the independent claim of the invention. The dependent claims contain preferred embodiments of and improvements of the invention.

The form of realization of the device for stepwise switching for various values of the step in the gradual switching of the distributor housing allows the preferred way to skip the inactive outputs a distribution device for the gradual switching of the distributor housing, so that such inactive outputs are not connected as current outputs with a common inlet connection. Due to this, in the first�'s, eliminates the problem of reducing the pressure on inactive exits through drain pipes and, secondly, the delay in time by appearing in the famous water distribution devices intermediate step on the inactive outputs. The distributor body when you step in a phased changeover, when, after cutting off the supply of water is a drop of pressure in the beginning on the current output switches at one stage to the next active way, and a step in the phased switching only allows for one step increment to the nearest adjacent active output or more stepper increments to more remote active. The successive steps of a phased switch, depending on the distribution of outputs, have a different value, which varies with a change in the distribution of outputs.

Required, respectively, the step size between successive active outputs can preferably be set at the dispenser, wherein the dispenser is preferably provided separate outputs mounting means by which individual outputs can be marked as active or inactive for the device phased switching.

Install tools when connecting the outlet leading to accession to Oro�the DIY installation of the line and/or when trimming output can be automatically configured as active or inactive. Mounting means are preferably mechanically just switchable by the user, preferably by hand and without tools, in particular turning or rotating the setting lever.

Different step size phased switch determines the length of stroke of the moving under the influence of high pressure water in the process phase of the irrigation and/or when the pressure of the piston, the greater the move of the piston corresponds, as a rule, the large value of the step phased switching.

The preferred way of installation tools act as variably limiting the displacement path of the stops to move the piston and interact with mating structure that combines the movement of the piston and the rotation of the distributor housing. The response structure is made preferably in the form of a step in the direction of the phased shift Manager Cam in the form of a series of paired struts. Gradual switching of the distributor housing is preferably in a known manner along the rail of the spiral spindle with a freewheel. At a given step of the spiral, angular step rotary motion is proportional to the axial motion of plunger, respectively, the axial displacement associated with the piston of the spiral.

Below the invention d�the tion is explained with reference to the drawings based on a preferred example of the implementation.

It is thus shown:

Fig.1 - neck junction cover,

Fig.2 - valve with the casing in section,

Fig.3 is another view to Fig.2,

Fig.4 - scheme switching the scan Manager Cam

Fig.5 - option to figs.4.

Fig.1 shows an oblique top view of the upper portion of the casing GE water distribution device that includes a total of six outputs. The casing contains the total for all outputs of the inlet connection of the EA connects to the inlet line, such as a hose from a computer-irrigation.

Under shown in Fig.1 open up the lid, there are several installation levers SH for manual activation by a user without the aid of a tool that can occupy at turn two positions. Shown in Fig.1 installation levers for SH unambiguous relationship to the corresponding outputs in the following description are indicated by numbers N3, N4, N5 and N6. The setting levers are used for the marking corresponding outputs them as active or as inactive. Mounting the levers H3 and H4 are in the position that corresponds to the marking corresponding to them outputs active outputs. Mounting the levers H5 and h6 are in the position marks corresponding outputs as inactive outputs. The casing can be provided with labels On for provisions related�granted to active marking and Off for provisions related to an inactive labeling.

The dispenser of Fig.1, for which accepted six outputs, contains only four of the adjusting lever. Two out of the six marked without long-term installation media as active outputs and cannot be marked as inactive outputs. This is in fact the position that it is advisable to use a water distribution device, at least, with only two connected to the irrigation machine outputs.

On the housing GE water distribution device has a transparent cover panel as FK reference window, through which, as can be seen from the subsequent description, it is possible to obtain information about the position of rotation of the distributor at the moment in cooperation with the output as a current output. The top panel FK can be performed on the casing are also removable.

Fig.2 and 3 with different angles, shows the water distribution device represented in Fig.1 embodiment the enclosure slit. In this image from the installation levers can see only the levers H3 and h6. Installation levers mounted on the housing with the possibility of rotation around the axes ON and on, facing away from the arms relative to the rotary axis side contain the Cam stops N3 and N6, respectively, for the device in stages�about switching are marked active or inactive exit. In the installation lever H3, which marks the exit A3 as active, the Cam stop N3 acts parallel to the axis of rotation DA of the device for stepwise switching, which is described below in detail, in the direction of the latter, i.e. in Fig.2 down. Installation the lever h6 is in a position that is correlated with the A6 exit marking device for stepwise switching as inactive. Cam focus N6 adjusting lever h6 is in the position of turning to the side.

For the device phased switching apply generally accepted basic principle with rotating around the axis of rotation DA of the spindle with spiral WE are turning in the direction around the axis of rotation DA of the overrunning clutch device and movable axially in the direction of the axis of rotation of the piston and the distributor housing. In the example of Fig.2 VK distributor housing contains a disk-shaped area, which is divided into six equal angular segments. One of these six segments forming the recess AU in the body of the disk and interacts accordingly with the current output. The other five segments at its bottom disk surfaces are seal DS that interact with lying in the plane of the mating surface of the casing, the purpose of the seal made in the casing channels as outputs. The space on top of the distributor housing VK � operating mode filled with water and communicated with the water inlet accession EA. The design of the distributor housing with a disc-shaped plot for seal inoperative outputs is particularly preferred, since the current in the inner space WR water pressure is pressing seal DS to the mating surface of the casing and seals securely especially. The distributor housing can be rotated device phased switching around the axis of rotation DA.

Fig.3 as the preferred option improvements depicted displacement means in the form VN Cams on the underside of the disc-shaped section of the distributor housing VK. The Cams are preferably in the axial downward direction for the sealing device and the rotational movement of the distributor housing during a phased stepper switch contribute to the fact that the distributor housing is displaced in the axial direction from the outlet containing the outputs of the casing. The offset is preferably so large that the sealing device DS is completely removed from the front of the distributor housing to the housing surface, which is interacting with the sealing device forms a sealed surface during the processes of irrigation. Cams VN preferably in the direction of gradual switching have beveled surfaces which are adjacent to the edges of the outputs and, gliding along them, contribute to axial displacement of the distributor housing. Due to the axial movement of the distributor housing on the land movement step of a phased switch is preferably reduced friction and simultaneously cleaning effect is achieved, so that during removal of the sealing device with the mating surface running in between water washes away dirt particles and thereby reduces the wear on the sealing device and the mating surface. The reduction of friction is advantageous, in particular, for large values of the step phased switching.

The device is a phased switch contains the spindle with spiral WE are, which is fixed to the casing sleeve HU is rotated around the axis of rotation and, in addition, axially displaced in the direction of the axis of rotation DA. The spiral WE are in its rotational movement around the axis of rotation DA, as well as in its axial displacement in the direction of the axis of rotation DA is connected to the piston TO. The piston TO rely on the axis of the ring DR. Ring DR also contains a sliding seal that seals up water interior space WR. The piston on its upper side is pressed downward by a return spring RF, which is centered in the sleeve FH, and at its other end supported on the casing.

In the area of the spiral WE installed disk FS as part of the device organography, which is sent in a spiral. Disk FS has six saw-tooth gear, which interacts with a corresponding mating structure on the casing as an overrunning clutch. Disk FS is being pressed down by a spring, but in its function overrunning clutch when rotated in the arrow direction of rotation of the freewheel can be displaced axially on the gear teeth and thereby rotate relative to the casing in the direction of the arrow. The rotation of the disk FS in the opposite direction is blocked interacting with the gear casing.

The images in the context of Fig.2 and Fig.3 the piston is shown in a lowered position in accordance with low pressure in the inner space WR. This corresponds to the state when the computer overrides the irrigation supply. The VK distributor housing during rotation around the rotation axis DA is rigidly connected to the piston TO and in the axial direction essentially not shifted. The piston TO while maintaining a rotary connection to the distributor housing is moved relative to the latter in the axial direction. In the presented position, the rotation of the distributor housing, marked the adjusting lever D3 as the active output A3 forms a current output for the next irrigation. Figure 3 located above the ring circle DR this indicates the position of the turn in the direction of con�roll the window FK, so that the user can obtain from him information on the current position of rotation.

To start the irrigation process the computer-irrigation opens at the output A3 of the valve and the water under a high pressure source, usually in some bar, increases the water pressure WR in the inner space and displaces the piston TO against the opposing force of compression spring RF in the direction of the arrow KN relative to the housing of the dispenser VK. The distributor housing under the action of pressure of water drawn in to the outputs and isolates all outputs except output current A3, the internal space is relatively WR. Thus axial movement in the direction of the piston KH captures TO spiral and WE drive FS device overrunning clutch rotates around the rotation axis DA relative to the spiral WE are in the freewheel direction. The piston when moving in the direction of KN is not rotated around the axis of rotation. The rotational connection between the piston and the distributor housing is maintained, for example, by projecting into the piston along the axis of the section of the distributor housing. When the irrigation process after a programmable computer irrigation time irrigation ends, the computer stops supplying irrigation water into the intake accession EA water distribution device and the piston TO axially shifted backward by a spring in direction FR� arrows KL in the direction of the distributor housing VK. In this spiral WE are in exactly the same once again axially moved together with the piston KO. Through the guide between the spiral coil and an overrunning clutch disk FS clamped up against the marked arrow on the disk direction, however due to the gearing in the casing cannot rotate relative to the casing. Equally by means of a spiral guide this is rotation around the spindle axis of rotation, which also leads to a corresponding rotation of the piston and TO the distributor housing around the axis of rotation. Due to the sixfold gear drive FS and the mating surface on the housing when you turn the distributor housing one of several specific provisions of the corner is always provided as the target position.

Bush HU around the spiral WE mounted on the housing with the possibility of displacement in the direction of the axis of rotation. By manually pressing the sleeve axially in the housing enclosure switch dispenser may continue regardless of the water flow.

Measure of rotation of the distributor housing VK during the reverse movement of the piston and the spindle is determined by the step of the spiral and axial displacement.

In contrast to the usually applied water distribution devices with the principle of gradual switch, which when equal on each phase switching, limited stationary pack�rum stroke of the piston, the value of the step angle of the phased switching of the distributor housing is always equal to the stepper increment IW from one output to the next output, according to the invention is provided that can be set variable step size for stepwise switching of the distributor housing and, in particular, the steps of the phased switching can be carried out in one step with step size multiple of the stepping increments.

To this end, in the preferred form of implementation may be set to a variable pitch of the piston, while a task form the setting lever and its Cam abutments in cooperation with moving together with the piston in axial and rotational direction control Cam in the form of a conjugate focus. In this, the control Cam in the direction of the phased switching repeatedly stepped curved around the axis of rotation DA and has several levels, from which one can see the thrust stage, reference numerals S1, S2 and S3. C exits the water distribution device, designated as A1 and A2, which are not marked as inactive outputs are linked fixed stops in the corresponding Cam stop N3 shows the adjusting lever H3 axial position. Fig.2 these fixed stops covered by a sleeve FH and reverse RF spring.

Surface conjugate stops separate stupine� Manager stepped Cam evenly spaced from step S1 to step S5 in the circumferential direction, forming direction SR phased switch, around the axis of rotation with equal speed increments.

Method of functioning is represented in the images in the context of a form of implementation of the device for stepwise switching is illustrated further on the basis of scan Manager SS Cam with steps S1 to S5 and the respective separate outputs from A1 to A6 of the provisions of the stop of Fig.4. The scan Manager SS Cam and the distributor housing VK cyclically continues with both sides broken lines, through the provisions of emphasis to show the full scope of the Manager of the Cam.

As can be seen in Fig.4, the control Cam SS in the axial direction AR has five different steps S1 to S5. The control Cam in one of the positions of the piston is in the corresponding images in the context of the axial position respectively disconnected the water supply.

Of the six outputs of the water distribution device outputs A1, A2 marked long-term fixed stops AF1, AF2 as active. Further, as shown in Fig.1, the outputs A3 and A4 are marked mounting levers H3 and H4 as active outputs, whereby the Cam lugs of the adjusting lever H4 and H3 additionally positioned eccentric to the Manager and act as stops on the provisions of rotation of the locating levers H3 and H4. Resistant� surface of the fixed stops AF1, AF2, and Cam abutments N3, N4 installation of levers H3 and H4, are located in a plane perpendicular to the axis of rotation DA. The angular increment of gradual switching between two directly adjacent in the circumferential direction outputs denoted by IW.

Fig.4(A) presents the image Manager SS Cam in accordance with the position of rotation in the images section from exit A3 as output current. Also shown in rotation around the axis of rotation DA is connected with a control Cam on the distributor housing with VK, scalloped, AU, which is shown in the position of rotation is located above the exit A3 and once irrigation provides the feed passage through the inlet joining the water distribution device of water in the exit A3, while the remaining outputs are presented in Fig.4(A) position, rotate the distributor housing clipped.

In the present position of rotation of the eccentric and of the distributor housing step S1 conjugate focus is located at a distance D1 opposite the Cam stops N4 of the adjusting lever H4. The distance between the steps from S2 to S5 managing the Cam and thrust AP plane indicated by the positions D2, D3, D4 and D5. The distance from D1 to D5 evenly increase, preferably always at equal speed increment IS between successive steps.

When starting the process of irrigation, based on shown in the pictures section positions of rotation and pressure of the internal space WR, the piston together with the control Cam is displaced along the axis from the distributor housing until such time as the step S1 is not facing the Cam focus marking N4 exit A4 as the active installation of the lever H4. The course of movement of the piston is limited, thus, the distance D1, so that upon subsequent return movement of the piston after the cut-off of water flow is reversed axial movement by this value D1 and the corresponding axial displacement by the amount D1 of the rotation of the piston, the Manager of the Cam and the distributor housing to the corresponding angular step. In this way the displacement D1 is coordinated with the step of the helix so that the distributor housing is switched to the next in the direction of the phased switching output A4, as shown in Fig.4(B).

In shown in Fig.4(B) the position of the turning the control Cam and the distributor housing mounted on the inactive labeling of the outputs A5, A6 installation levers H5 and h6 through steps S1 and S2 do not result in effective emphasis. Possible stop positions marked by dashed lines. Stops AF1, AF2 and N3 are located above the steps S3, S4 and S5, despite the fact that, according to step S3 to D3 has a minimum distance�. When you start the next process of irrigation, in which the output of A4 is loaded with water as a working outlet, the piston together with the control Cam is shifted axially so on are the pathways to D3 until the degree of risk emphasis S3 will not encounter corresponding to A1 fixed focus AF1. After the process is complete irrigation of the piston together with the spindle is moved axially back along the path of movement of D3 and thus through the guide spiral and locking overrunning clutch is switched on at step angle, which corresponds to the axial path of displacement D3. In this way it is assumed that the path of displacement D2, D3, D4 and D5 are designed so that upon return of the piston corresponding angular steps two, three, four and five step increments, with a step increment represents the angle between the two following each other immediately exits. At the completion of the irrigation process at the output of A4 as the current output occurs when returning the piston to the rotation of the piston and the distributor housing by three angular increments, so after that scallop AU distributor housing is marked on the long-term as a active exit A1 and marked as inactive outputs A5 and A6 are skipped in one step phased switching.

On the basis of directly Smin�x, tagged for a long time as an active outputs A1 and A2, we obtain the maximum value of the step rotation is five angular increments as a gradual switch from exit A2 directly to the output A1, if there are no other marked as active outputs. Located on Fig.4 directly to the right of the stage S1, the area Manager Cam at work is not involved and is situated at the level of step S5.

It is obvious that the phase switch variable in the described method action value of the angular step, at any position rotary switches, always leads respectively to the next active way, and a certain fixed or variable stops the path of movement is always proportional to the angular step to the nearest marked as active output.

Fig.5 shows a variant to Fig.4, and in this case it is customary that the newly two outputs A1, A4 marked with the corresponding fixed stops as a long-term active, with the difference that these are marked as long-term active outputs A1 and A4 are not directly related, but are offset relative to each other by three angular increment. In this case we get the maximum value of the angular step in a phased switching of the distributor housing is only three Uglova� increment, if there is no other marked as active output. The driven Cam can be restricted in this case, three steps S1, S2, S3, which follow each other in the circumferential direction. The remaining sections of the governing Cam not participate in the work and located at the level of step S3 or below.

Above and in the claims, as well as extracted from the drawings the features, as well as their different combination, can be advantageously implemented. The invention is not limited to the described examples of implementation, on the contrary, in the framework of professional knowledge, it can be repeatedly modified, in particular the distributor housing may also be made cylindrical with radially spaced outputs or also obliquely disposed sealing surface between the distributor housing and exits.
