The free end of the rod is passed through the hole of the perforated partition and placed under it. 1 ill.

Description

FIELD OF THE INVENTION This invention relates to plumbing fixtures and can be used in domestic water systems.

The aim of the invention is to prevent loss of water when the head is switched back on, increasing the reliability and durability of the system.

The proposed device is shown in the drawing.

The housing 1 is divided by a partition 3 into two halves - the upper and lower. In the baffle 3 there is a seat in which the valve 7 is located. The valve 7 is designed so that it has positive buoyancy. A cover 4 is screwed into the housing 1 from above. To ensure tightness, a gasket 6 is installed between the housing 1 and the cover 4. A screw connection is provided on the top of the cover 4 for connecting a water tap 2 to the outlet pipe. . A rod is connected to the float 7, the free end of which is passed through the hole of the perforated partition.

The device operates as follows.

When the faucet is opened (not shown in the figure), water begins to flow into the outlet pipe 2 and fill the upper cavity of the nozzle. Valve 7 will not float, as it is partially washed by water and cannot float. To start the water, it is enough to lightly press the valve stem 7 with your finger. In this case, the valve 7 is completely washed with water, as a result of which a lifting force arises and the valve 7 floats. Water from the upper cavity of the nozzle begins to flow into the lower one, and from there through the holes in the cover 5, which is also a strainer, begins to flow out. When the pressure is turned off, the water remaining from the water flows out of the nozzle and the valve 7, under the influence of its weight, sits in the saddle, blocking the pipeline. When the pressure is turned on again, valve 7 does not allow water to pass through, as it is partially washed by water and cannot float. In this case, despite the open water tap, there will be no water leakage from the water pipe until it is pressed again

finger on the stem will not lift valve 7.

The use of this nozzle avoids the frequent opening of a water tap. If the faucet is equipped with a nozzle, then it is enough to open it once, having adjusted the necessary water supply. After that, all actions are performed only with the nozzle. To start the water, it is necessary to easily press the valve stem 7 from below. In this case, valve 7 pops up and water starts to flow out through the nozzle. If it is necessary to stop the water supply, it is enough to put the valve 7 in the saddle with your fingers and put the water out of the lower cavity of the nozzle, and the valve 7 will not be able to float on its own due to its partial wettability. In some cases, this nozzle reduces the number of water taps in the system. For example, in public places, if there are several washbasins

Cove, it is enough to install one tap on all washbasins, providing each with the proposed nozzle.

The feasibility of the proposal is determined by the complete prevention of emergencies when the head is switched back on and the loss of water is eliminated, as well as by the increase of the system reliability and durability.

Formula A nozzle for a faucet containing a body with inlet and outlet openings, a positive buoyancy valve connected to the stem, and a valve seat located across the body, about it is preferable that it is provided with a perforated partition installed in an outlet made in the bottom of the housing, and the free end of the rod is passed through the hole of the perforated partition and placed under it.
