(54) DEVICE FOR MAINTAINING LEVEL, WATER

IN DRINKING

one

The invention relates to agriculture, in particular to animal watering devices.

A device for watering animals is known, including an intermediate tank with a float valve and a bowl drinkers installed at the same level 1.

The disadvantage of such a device is its unreliability in operation.

It is also known a device for maintaining the water level in drinking bowls, including a water level regulator mounted on the supply pipe, made in the form of a vertical stem mounted in the valve body, at the end of which a piston element is placed, dividing the body into the upper and lower cavities, intermediate capacity with a valve-float mechanism installed in it, with a water level regulator 2.

However, this device is complicated in construction.

The purpose of the invention is to simplify the design.

This goal is achieved by the fact that the device for maintaining the water level

in the drinkers it is provided with an air nozzle, by means of which the valve-float mechanism communicates with the upper cavity of the casing of the water level regulator, and in the piston element there is a through-calibrated opening connecting the upper and lower cavities of the casing.

FIG. 1 shows the device, the general scheme; in fig. 2 - water level regulator, section. The device circuit includes bowl drinkers 1, intermediate tank 2 with valve-float mechanism consisting of float valve 3 and float 4. Cup drinkers 1 and intermediate tank 2 communicate with each other via pipe 5 with vertical outlets 6. To maintain a constant water level The device is equipped with a water level regulator mounted on the supply pipe 7, made in the form of a valve 9 installed in the housing 8 with a vertical rod 10, on the end of which is located the piston element I, which divides A port 8 to the upper 12 and lower 13 cavities, which communicate with each other through a through-calibrated orifice 14. The upper cavity 12 communicates via an air nozzle 15 with a valve-float mechanism installed in intermediate tank 2. The lower cavity 13 of the regulator is connected through nozzle 16, pipe 5 with a cup drinking water 1 and an intermediate tank 2.

The device works as follows.

When the cup drinkers 1 and the intermediate tank 2 are not filled with water, 1 the float valve 3 is open, and the float 4 is in the intermediate tank 2 in the lowest position. In this case, the upper cavity 12 of the regulator is communicated with the atmosphere through the air nozzle 15. Water from the supply pipe 7 enters the lower cavity 13 of the regulator. As the lower cavity 13 is filled, due to the fact that the pressure of water acting on the bottom of the piston element 11 exceeds the pressure of water acting on the upper part of the valve 9, the latter opens and the water begins to flow through the pipeline 5 into the intermediate tank 2 and the cup drinkers 1. After the water in the cup troughs 1 and intermediate tank 2 reaches the required level, the float 4 will take up its extreme upper position, and the float valve 3 will close the air nozzle 15 and thereby stop reporting the upper olosti 12 with the atmosphere. Simultaneously with the filling of the lower cavity 13, the water through the calibrated orifice 14 fills the upper cavity 12, as a result of which the pressure force of water on the piston element 11 from above increases, since with the float valve 3 closed, the volume of the upper cavity 12 is limited. The moment when

The water pressure forces acting on the piston element 11 from above and below are balanced, the water pressure force acting on the upper part of the valve 9 lowers it to its lowest position and the water supply to the intermediate tank 2 and the cup drinkers 1 is stopped.

The proposed device, compared with the known, is simpler in design and more reliable in operation.
