The regulator arranged, and connected devices work: direct pressure regulator, shut-off valve, relief valve (UCS), a filter for separating dust and mechanical particles.
The pressure regulator illustrated in Figure consists of a working valve (6), which is simultaneously shut-off valve seat (12) of the valve housing (3), wherein the fixed seat (7).
The regulator valve means operating rod (15) and the lever mechanism (10) is connected to the working diaphragm (8).
The feed gas to the control medium or high pressure passes through the inlet strainer and passing through the gap between the working valve (6) and the seat (7) is reduced to low pressure on the outlet nozzle and is supplied to the consumer.
The pulse from the output pressure is transmitted to the cavity submembrane knob control line (21). The membrane via a lever mechanism (10) and stem (15) moves the operating valve and thereby regulate the output pressure. Spring adjuster (16) and an adjusting nut (18) intended to adjust the output pressure.
In the center of the membrane (8) is a relief valve (13) with the setting spring (17). The regulator has a cover relief channel for gas to the atmosphere. Channel for footprint relief is protected from mechanical particles in a metal strainer regulator (19) and equipped with a silencer for protection against vibration occurrence.
In the case of increasing the pressure regulator output beyond acceptable values Fp opens relief valve (13), providing a gas to the atmosphere.
By increasing or decreasing the output pressure of gas to a value setting the shut-off valve, a lever (10) moves the lever segment (9) to a position in which the ball shut-off valve (11) is disengaged from the lever segment (9) and the shut-off valve (12) under a spring (23) closes the valve seat (7) and gas supply is stopped. Shut-off valve and stops gas flow at an extreme increase in gas consumption and break the membrane.
Start the controller in the work is done manually after the elimination of the causes of the operation shut-off valve.
