Abstract

This invention relates to pipe fittings. The aim of the invention is to increase the reliability of operation by blocking the inlet channel when the medium is temporarily stopped. When the gas is temporarily shut off, the controlling valve 19 closes the saddle 20, and the main valve 10 closes the saddle 9. When the gas is supplied to the channel 27 again, the valve device is closed. 1 il.

Description

The invention relates to pipe fittings.

The aim of the invention is to increase the reliability by blocking the input channel during a temporary interruption of the medium.

The drawing shows a valve device, a section.

The device consists of a housing 1,; d having channels 2-8, and a seat 9, overlapped by the main locking element 10, spring-loaded 'springs 11 and 12 and connected with the piston 13, cover 14 with a medium outlet channel of the 15th calibrated 15 hole 16 for partial discharge of the medium from the piston cavity 17. A control valve 18 is installed on the body 1 with a control shut-off member 19 and a seat 20, a piston rod 22, 20, a piston 22, a cylinder 23, with a control channel 24, a spring 25 and a manual control ring 26. Gas is supplied to the inlet channel 27.

The valve device operates in the following manner.

In the absence of pressure gas main shut-off body 10 by the spring 11 is in the rightmost position on the saddle 9. gg piston 13 under the action of the spring 12 is also in the _p rightmost position and abuts the end of the housing 1.

The control locking element 19 under the action of the spring 25 is in its lowest position on the seat 20.

If you need to use gas equipment, a shut-off valve opens. Gas is supplied to the cavity 27 of the valve device. When the rod 21 of the control valve is pulled out (the ring 26, gas is supplied through the channels 8,7,6,24 and 2 under the piston 22 and when the ring 26 is released, the gas pressure is in the raised open ί 45

And position. Gas passes through channels 8, 7, 5 and 4 to the piston 13, squeezes it to the left position, and the main one; the locking element 10 opens the exit 1 ^ $ per channel 15.

When the gas supply to the 'cavity 27 is stopped, the locking body 10, under the action of the spring 11, sits on the seat 9. Under the action of the spring 25, the locking control 19 sits on the seat · 20. Under the action of the spring 11, the piston 13 moves to the right position, locking the seat 9, since the gas is displaced through the channels 5, 4, 3 and 2, the calibrated hole 16 is in the cavity 15. When the gas is re-fed into the cavity 27, the valve device will be in a closed state until the control valve 18 is pulled out of the ring 26.

Claims (1)

Claim A valve device for household gas equipment, comprising a housing with a medium inlet and outlet channel and a seat blocked by a main locking element associated with a spring-loaded piston actuator, and a control valve, spring-loaded The supporting element of which is connected through the rod to the actuator, the channel connecting the medium inlet channel with a piston cavity of the drive of the main locking member, characterized in that, in order to increase the reliability of operation, a piston is installed on the rod of the controlling locking member, in the cylinder with a control channel in the side wall connecting the medium inlet channel with the piston cavity of the cylinder, the piston being installed with the possibility of overlapping in the lower position of this control channel.
