54) AUTOMATIC DEVICE FOR WATER SUPPLY

This invention relates to the field of agricultural water supply. The device is intended to automatically supply water to a reservoir. Automatic devices are known, including a housing mounted on a water conduit pipe and a water throughput valve installed in it with a flooded lead float. The CAVITY of the float communicates with the cavity of the tank through the holes made in the bottom of the body fll. In these devices, the filling of the float cavity water and its emptying happen very quickly, which leads to abrupt closing and opening of the culvert opening by the shut-off valve, which results in the occurrence of 0 Hydraulic hammer pipelines that cause harmful vibration and an accident in the water supply system. It is known an automatic device for supplying water to tanks, consisting of a regulating tank with an actuator, a rod connected at one end with a locking valve, and with a regulating capacitor. cords, flexible hose 23. In this device, the regulating capacity has the same section in height / therefore the amount of incoming fluid when it is filled is constant, as a result of which the regulating capacity quickly raises the weight and the shut-off valve closes the supply pipe. In this case, a hydraulic shock occurs in the pipeline, especially at high pressures in the system. The aim of the invention is to reduce the force of a hydraulic strike when opening and closing the valve. The goal is achieved by the fact that the regulating capacitance has a variable height section, and its. the cavity and the water tank are connected to each other by a flexible hose. The drive is made in the form of cargo, connected by a train with a regulating capacity. The drawing shows the proposed automatic device for water supply. It contains a regulating tank 1 with a cross-section of variable height, i.e. with transgenic - with a volume that is connected to load 3 with a cable 3 to the top, and rigidly connected to an eu with an eepor valve 4 of the stem 5 passed through the gland, into the lid of the hydrobox 6 installed on the water supply pipe 7. and associated water supply, pipe 8 with-9 reservoir for water. The cavities of the regulating vessel 1 and the reservoir are interconnected by flexible hose 10.

The automatic device works as follows.

As water is consumed from the re. Air 9, its level decreases. Simultaneously with a decrease in the level of in-tank 9, the level of water in the regulating tank 1 also decreases. At the same time, the quantity of water in the tank is reduced slightly at the beginning, then gradually increases, since its emptying occurs stepwise, starting from a smaller "volume". As the container 1 empties under the pressure of water in the water supply pipe 7 and the load 3, the container slowly rises, and the rod 5 lifts the valve .4; x ;. gradually opens the access from the water supply pipe to the cavity of the hydro box 6 .. Water from the hydro box through the water supply pipe patrugGk 8 enters the tank 9 and fills it.

Upon reaching the level in the tank 9 above the bottom of the tank 1, water from the hydrobox through the flexible hose 10 enters the tank 1, where the filling occurs sequentially from the bottom up, starting with a large volume. As the container is filled with water, its weight gradually overcomes the force of the load 3 and the pressure in the water pipe 7, and the load on the valve 4 occurs gradually, especially at the end of filling due to the successive reduction of the container cross section; As a result, the shut-off valve 4: immediately closes the supply line. After the valve is fully shut off, the flow of water to the tank 9 is stopped.

Using the proposed astomatic device for /: supplying water to the reservoir reduces the force of water hammer in the pipeline when filling and emptying the reservoir.
