Description

The invention relates to agricultural water supply. The circuit of the invention - improving the reliability of the device is achieved by the fact that in the water supply device to the tank 1 containing the supply pipe 2, the chamber 4, including the diaphragm 5 with the valve 6, the float 16, the chamber 4 is bounded above by a membrane 8 rigidly connected to the diaphragm 5 and communicated with an elastic tank 12 placed between the movable plate 14 connected with the float and the fixed plate 13. 1 sludge.

The invention relates to agricultural water supply and is intended for automatic control of the flow of water into the tank.

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

The automatic device for supplying water to the tank contains a tank 1, a supply pipe 2, a housing 3 and a chamber 4. The bottom part of the chamber 4 is made in the form of a diaphragm 5 on which is fixed a valve 6 mounted on the inlet pipe 2 installed in the bottom of the housing 3, reported with the tank 1 holes 7. The chamber 4 is bounded above by a membrane 8, rigidly connected through a rack 9 with the diaphragm 5. The chamber 4 is connected through a nozzle 10 and a tube 11 with an elastic tank 12, which is located between the plates 13 and 14. One of the plates 13 is fixed adjustably on the tank and podizhnaya plate 14 by means of rigid rods 15svyazana with a float 16 mounted in the container 1,

Automatic device for supplying water to the tank works as follows.

Water from the supply pipe 2 and hole 7 enters the tank 1 “When the tank 1 is filled to a certain level, the membrane 8 gradually bends down under the action of the mass of the water column. At the same time, the force through the rack 9 and the diaphragm 5 is transmitted to the shut-off valve 6. The air in chamber 4 is compressed ₀ By the time the tank 1 is filled to the specified upper level, the float 16 rises up under the action of the buoyancy force of water (Archimedes force). At the same time, the movable plate 14 rises and the elastic container 12 increases in volume. The air from the chamber 4 is forced out through the jet 10 and the tube 11 into the elastic tank 12. The valve 6 closes smoothly. The displacement of air from the chamber 4 into the elastic container 12 continues until the pressure in them is equalized. With

This force of air pressure on the membrane 8 from the bottom up decreases, and the force from the mass of water from top to bottom remains on the same without change. Therefore, the force of pressing the valve 6 to the upper end of the inlet pipe 2 increases,. ensuring reliable closure. The area of the membrane 8 is several times larger than the area of the diaphragm 5, to which the valve 6 is attached.

After shutting down the pump as water flows, its level in the tank drops. At the same time, the float 16 goes down. Under the influence of its mass, the elastic container 12 is compressed between the fixed 13 and the movable 14 plates. The volume of the elastic container 1 2 decreases, the air pressure in it increases. The air from the elastic container 12 is displaced through the jet 10 and the tube 11 into the chamber 4, the air pressure in the latter increases. The total force acting on the membrane 8 from the bottom up, increases. As the water level in the tank decreases, the force acting from top to bottom on the membrane 8 decreases. When the water level in the tank decreases to a certain value, the membrane 8 rises up and the valve 6 opens. Water supply to the tank is resumed. The cycle of work is repeated.
