The invention relates to water and can find application in various fields of national economy, in particular in railway transport.

A device for refilling (RF Patent N 2117595 from 20.07.98) containing placed in the tank coming out of water-filled pipe and accompanied with trumpet valve device comprising an annular valve rigidly connected with opposite water outlet to the tank reflector placed in the cavity of the float carrying a seat for the valve, with the formation of the annular tank clearance relative to the inner surface of the float and vozmozhnyye in itself hollow body, rigidly connecting the annular valve with a water-filled pipe and reporting water-filled tube with a cavity formed by the reflector and the inner wall of the float and choke placed in the enclosure and in communication with the overflow pipe.

A disadvantage of the known device is unstable at high pressures and water is not filling the tank with water by controlling the flow of water from the overflow pipe.

The technical task to be solved by the invention is the provision of the necessary water level in the tank regardless of the pressure of water coming from the pipeline. The need for high pressure water pipelines due to severe frosts, which instantly freeze the incoming water in the connecting rod before the water enters the tank of the car.

This problem is solved due to the fact that the device for filling the tank with water containing communicated between a water-filled pipe, a valve device and a device for monitoring the completeness of filling of the tank water, which includes communication with the overflow pipe tube, the latter is made with a hole, and Tory made in the form of conical springs and installed in the fitting.

The device can be equipped when using two or more water-filled pipe valve box with flaps, each of which includes consistently located on the rod and preloaded to each other washer, flat annular elastic element, ring, disc elastic element and the nut, and the washer and nut are made with the protrusions in contact with the ring.

The essence of the device illustrated by the drawings.

In Fig. 1 shows a connecting battery tank with the device prepared for installation on the car. In Fig. 2 - valve design valve boxes.

Device for filling the water tank consists of a valve box 1 with two fittings 2, intended for installation and mounting on a water-filled pipes 3 by screws 4 and retaining straps 5. The fittings 2, inside the valve box 1, there are two spring-loaded valve 6, each of which may be open or closed position depending on which side is filling the car with water. Through the bottom of the valve box 1 skipped nipple throttling element 7, for connecting the upstream cavity with overflow pipe 8 pipe 9 with a tip 10, which moeiy finish filling tank with water. On the valve tube 1 is hollow strut 12 with valve 13. The valve is stationary mounted reflector 14 with a movable about its axis, a work cylinder 15 having a seat 16, and top dressed and fixed the float 17.

The device operates as follows. When water in the tank through one of the water-filled tubes 3 valve 6 valve boxes 1 to the water pressure opens and connects the cavity of the valve box 1 reflector 14, the working cylinder 15 and the tank. Through the annular gap formed by the valve 13 and the seat 16, the incoming water is discharged into the tank. When reaching into the tank of the desired water level, the float 17 with a working cylinder 15, moving up, reduces the annular gap between the valve 13 and the seat 16 of the working cylinder 15. The reduction in flow area creates the water pressure in the working cylinder 15. As a result of water through the annular gap between the walls of the reflector 14 and the working cylinder 15 is supplied into the cavity between the bottom of the reflector 14 and the bottom of the working cylinder 15, creating sufficient force to contact saddle 16 with valve 13. The ingress of water into the tank stops. At the same time water from the valve boxes 1 through the nipple 7 and the tube 9 is sent to an overflow pipe 8. A thin stream of water under Vij supplied into the water tank, possible seepage of water into the tube 9, and from this to an overflow pipe 8, indicating the filling tank with water, which, however, is not yet filled. To avoid this situation has a hole 18 through which the filtered water is discharged into the tank and is not placed in the overflow pipe 8.

If all the water flowing into the pipe 9 does not have time to go through the hole 18 in the pipe 9 is provided by the slot 19, made at its end (tip 10). The water passes through the slot and into the tank.

When full, the tank water, the water begins to flow into an overflow pipe and refill water tank ends.

To increase uptime of the device it is advisable to use a coarse filter (not shown) and a fine filter.

The function of the filter can perform a conical spring, which, along with this feature allows you to minimize the ripple of the water supplied to the water-filled pipe.

To improve the efficiency of the valve chest, the valve is made on the shaft 20, on which a preload to each other is fixed to the washer 21, a flat annular elastic element 22, the ring 23, plate elastic ele the CSO efforts compression, acting on the elastic elements.

In the process, the elastic elements interact respectively with the end face and the inner surface of the fitting, completely eliminating the ingress of water to another water-filled pipe, because the pressure in the valve box shall preload elastic elements to the respective surfaces of the nozzle.
