The invention relates to level control or level control devices, for example, water distribution control in wells of a closed low pressure water supply network.

The aim of the invention is to increase the accuracy of level control and expand the operational capabilities of the device.

In FIG. 1 shows a device, a vertical section; figure 2 - the location of the level sensors along the route of the water distributor.

The device includes a tubular water outlet 1. to which a membrane control chamber is mounted on brackets 2, which is formed by a membrane valve in the form of a locking disk 3, membrane 4 and a rigid wall 5. An air inlet 6 with a floating valve and an air outlet and a drain is fixed to the latter nozzle 7. A guide cup 8 with a locking screw in the bottom 9 is sealed along the axis. A ribbed guide rod 10 is fixed to the locking disk 3 with a throttle tube along axis 11, which provides the cavity of the membrane control chamber 2 with by discharge 1, the membrane control chamber 12 is assembled on a tubular water outlet 1, embedded in a blind partition wall 13 in the intake well 14, by means of a drain pipe 7 and remote hydraulic communication 15 with level sensors consisting of an inlet pipe 16, the housing 17 , the float 18, the locking sleeve 19 and the drain fitting 20. The level sensors in assembled form 21 are installed along the route of the water distributor 22 at the level of the crest of the retaining-watering partition 23 in

transfer wells 24 located at the points of connection of the side water supply network 25.

The device operates as follows.

It is put into operation in the intake well 14 by unscrewing the locking screw 9 in the guide cup 8 of the control chamber 12. This opens the throttle tube 11, through which water enters the control chamber 12, through it through the drain pipe 7 via hydraulic connection 15 into the level sensor 21, where it flows out through the open drain fitting 20. At the same time, the locking disk 3 is released and under the pressure of the water, the opening of the tubular outlet 1 through which the water enters the lower downstream of the intake well 14 and then through the water distribution pipe 22 to the retaining and overflow weir 23 in the first overflow well 24. From it it enters the side water supply network 25. When the water rises to the outflow of the ridges of the retaining partition 23, the float 18 of the level sensor 21 pops up and overlaps the sleeve 19 fixed to it side openings of drain fitting 20. Water drainage from the hydraulic connection 15 and, accordingly, the membrane control chamber 12 is stopped. Water begins to flow through the retaining and drain baffle 23 into the downstream to fill in all the subsequent overflow and closing water distributors of wells 24 and the lateral water supply network 25 connected to them. When the wells reach the set levels, the water drain through the level sensors 21 stops during hydraulic communication 15, the working chamber 12 is filled to its full capacity, excessive pressure is created on the locking disk 3, which accordingly moves and closes the tubular outlet 1. The flow of water into the water distributor 22 and the water supply network 25 is stopped. When the set water level decreases in a well in the above order, the drain fitting 20 of the level sensor fixed in the well 24 is turned on, the flow of water through the hydraulic connection 15 starts. The working chamber 12 is freed from overpressure and the locking disk 3 is pressurized.

water moves, opening the tubular outlet 1 and the water through the distributor 22 in transit through intermediate differential wells 24 enters the well, where

it is required to raise the water level to a predetermined level.

Equipping the membrane control chamber with an air inlet 6 and a diaphragm valve with a guide rod 10

gives stability and straightness to the movement of the valve, its oscillatory inertia is eliminated, the tubular outlet 1 is tightly closed. In this case, the level control accuracy is improved, unproductive discharges of water from the water supply network are eliminated and more than 15% of used water resources are saved.

Connection to the membrane control chamber via a remote hydraulic connection 15 of several sensors of 21 levels expands the operational capabilities of the device for watering the territory through an extensive water supply network, which increases the labor productivity of operating personnel by a factor of 2–3.
