Description

The invention relates to sanitary engineering and can be used in sanitary engineering systems.

The aim of the invention is to increase reliability by providing self-closing of the valve.

The invention is illustrated by drawings, in which Fig. 1 is a cross-sectional view of a crane; figure 2 is a section aa in figure 1; in Fig.3 - section bB in Fig.1.

The crane comprises a housing 1 with an inlet 2 and an outlet 3 openings, a locking element 4 located on the inlet 2 side and kinematically coupled to the actuator. The drive is made in the form of a slider 5 located in the housing 1 and a swinging arm 6, a short arm 7 of which is located in the groove 8 of the slider 5. The swinging arm 6 is connected to the housing 1 through the swing axis 9. A longitudinal channel 10 and a recess 11 are made for the slider 5 compounds

input 2 and output 3 holes. Moreover, the recess 11. is located at the end 12 of the slider 5 from the side of the inlet 2 and communicated with the opposite end 13 of the slider 5 by the channel 10.

An annular stop 14 is made in the housing 1 with the possibility of interaction with the end face 12 of the slide 5 facing the inlet 2.

The swing arm 6 is mounted in the slider 5 with the possibility of closing the crane under the weight of its long arm 15 at any open position of the locking element.

The free end of the housing 1 is closed by a plug 16.

The housing 1 and the slider 5 can be triangular, square or any other shape, based on elastic needs.

The locking element l is made in the form of coated with a sealing material

the end of the rod 17 connected to the slider 5.

The crane works as follows.

When forced upward movement of the lever 6 transfers the force to the slider 5, connected by the rod 17 with the locking element 4 m, moving the latter, opens the crane. In this case, along the longitudinal channel 10 of the slider 5, the liquid fills the space between the end face 13 of the slider 5 and the plug 16.

It is enough to let go of the lever 6 and the liquid entering the tap with its pressure acting on the locking element 4 and the body of the slider 5 tends to return the slider 5 to its original position, and the weight of the long arm 15 of the lever 6 contributes to this process. The mass of liquid between the stopper 16 and slider 5, does not allow a sharp return of the slider 5 to its original position, which ensures smooth closing of the valve by displacing this mass of liquid in the direction opposite to the flow through the longitudinal channel 10 in the slider

5, i.e., in the construction of the crane, water hammer does not occur.

The advantage of this faucet is that when it is used, water is consumed only in the volume that is required by the consumer when the faucet is forced to open.

Small leakage of liquid is possible only when the valve is not fully opened through the input of the lever 6 into the housing 1 of the crane. For ease of use, it is enough to put a small protective device on the lever 6, which will only increase the mass of the upper part of the lever

6, and all leaks will be claimed by the consumer.

With the tap closed, leaks are completely eliminated.

When the crane is fully opened, leaks are eliminated due to the tight contact of the end surface 12 of the slider 5 with the surface of the annular stop 14 of the housing 1.

A continuous jet is only ensured by forcing the lever 6 in the upper position, which is necessary in specific conditions if the crane is used, for example, in baths.
