(54) AUTOMATIC DEVICE FOR WATER SUPPLY TO TANK

one

The invention relates to the field of agricultural water supply and is intended to automatically regulate the flow of water into the tanks with a small flow rate of the water supply source.

Known control devices with float valves installed on the supply tank with water pipe and opening access to water immediately after the start of the water withdrawal from the tank 1.

In these devices, the process of water extraction occurs simultaneously with the filling. The supply of water to the tank is stopped only after the end of the water intake and the filling of the tank to the installed usable capacity.

In these devices, the process of water extraction occurs simultaneously with the filling. The supply of water to the tank is stopped only after the end of the water withdrawal and the filling of the tank to the installed usable capacity.

Such devices do not ensure uniform distribution of water among individual tanks that are connected to a low-capacity water supply source.

The closest to the technical essence of the invention is a device for regulating the supply of water to a pressure reservoir with a small flow rate of a water supply source, which is made with an adjusting tank mounted inside the water reservoir, in the cavity of which the valve floats of the supply pipe are placed, and a pipe provided with shut-off float valve 2. In this device, the regenlirovana upper H lower water levels in the tank is produced by two interconnected valves that LST dissolved design.

In addition, the use of float valves does not provide the required tightness, especially with large diameters and pressures in the system, and sufficient reliability of the device.

The aim of the invention is to increase the reliability of the device.

For this, in the proposed device, the control unit is equipped with a water insulating casing with a bottom placed around the regulator, a container, with a spring installed between the bottom of the casing and the regulating capacitor, and also with a rod connected at one end to the shut-off valve and the other g; the bottom of the regulating tank.

In addition, the device is equipped with a non-outlet pipe, made in the form of a composite, with an adjustable elastic section, a siphon outlet, one end of which is located; in the weight drive tank, and the other end

the cavity of the tank.

The drawing shows the proposed automatic device for regulating the supply of water to the tank, a general view.

The device is installed inside the tank

1and connected to the water supply pipe 2 through the pipe 3. The pipe 3 is fixedly attached to the perforated case 4 attached to the protective pipe

5 fixed casing 6.

Inside the perforated body 4, a shut-off valve is located coaxially with the nozzle 3 — a cup 7, tightly connected to the lower end of the protective tube 5 by means of a corrugated elastic hose 8, which serves to prevent water from the tank 1 from entering the cavity of the protective tube 5.

In addition, the valve 7 through the brush 9, located inside the protective tube 5, is attached to the bottom of the control tank 10 of the actuator, located on the spring 11 inside the fixed waterproofing housing 6.

The regulating tank 10 is connected to the atmosphere by means of the pipe 12, and through the flexible tubular element 13 to the cavity of the tank 1.

In addition, the cavity of the regulating vessel 10 is connected to an overflow pipe with a composite siphon water outlet consisting of an upper tube 14, an adjustable elastic section 15 and a lower elongated tube 16 attached to a fixed water insulating casing 6 and communicated with the cavity of the tank 1.

An automatic device closes the water access to the tank until the water volume in the control zone is consumed.

The device works as follows.

As the water from the reservoir 1 is consumed, its level decreases, and when it reaches the defined position, the regulating tank of the weight actuator 10 starts to empty through the composite siphon outlet. By the time the water reaches a predetermined lower level in the tank 1, the regulating tank 10 is emptied and under the action of force I rises upwards, while the rod 9 raises the valve 7 up and opens access to water from the water supply pipe

2 through pipe 3. Water from pipe 3 through the windows of the perforated case 4 enters

into tank 1 and fills it.

When filled to the upper level, water from tank 1 through flexible tubular element 13 enters the regulating tank.

10, which, as it is filled, is lowered under the weight and closes the inlet of the nozzle 3 with the valve 7. As a result, the water supply to the tank is stopped.

The use of the proposed automatic device for regulating the supply of water to the tank improves the tightness of the closure and ensures reliable operation.

In addition, the ease of changing the volume control zone (height) in the tank by changing the location of the elastic section in height or the length of the lower elongated tube of the composite siphon water supply system allows the proposed device to be used in tanks of different volume and height.

The device makes it possible to control the force of blocking the water inlet by increasing or decreasing the volume (weight) of a weight-type regulating container.
