Description

The invention relates to sanitary engineering and relates to the construction of a water dispensing tap.

The purpose of the invention is to simplify the design and improve performance by automatically shutting off the tap in the absence of water supply.

Figure 1 shows the faucet in the closed position, the section; Fig. 2 shows the water tap in the open position in the continuous discharge mode, a slit.

 The water faucet consists of a housing 1 with a drain hole 2, a horizontal partition 3, a supply 1 channel 4 located above the horizontal partition 3 with a hole, a cover 5, in the case there is a rod 6 with a gap 7 relative to the horizontal partition, having a piston 8 s in the upper part a gap 9, made with a groove on the upper end and overlapping in its lower position the inlet channel 4 with a lateral surface, in the lower part of the locking conical element 10 located in the opening 2 of the housing 1. The rod 6 and the piston 8 They are filled with an axial channel 11, and the locking element 10 with a diametral channel 12 located under the horizontal partition, the locking element 10 has a tip 13.

Water faucet works as follows.

When pressing the tip 13, the locking conical element 10 and the piston 8 are transferred from the lower position to the middle and the water from the supply channel 4 through the annular gap 7 and the drain hole 2 comes out.

At the same time, water moves to the drain hole 2 and in another way: through the annular gap 9 upwards, into the cavity above the piston 8, into the axial and diametral channels 11 and 12. At the same time, the pressure Pf under the piston 8 exceeds the pressure P2 in the cavity above the piston by loss of pressure in the gap 9, as a result of which pressure is equalized and the rod 6 is slowly lowered until the conical element 10 is seated in the opening 2. The valve is closed.

To ensure a constant drain mode, the tip 13 is pressed and the piston 8 is transferred from the lower position to the uppermost position, which leads to locking of the piston cavity,

. the differential pressure of the piston 8 will be maximum and equal to the differential pressure P, -P3 on the partition 3. As a result, the piston 8 will hang in the extreme upper position, ensuring a constant drain mode. In the event that the water supply to the faucet stops, the pressure differential across the piston disappears and the faucet closes.

If the valve is operating in a continuous drain mode, it is necessary to pull the tip 13 down to close the valve.
