About Gas Regulator

Description

                  

Gas regulator is the use of control valve body opening and closing pieces of the opening to adjust the flow of media to reduce the pressure of the media, while the role of pressure through the valve opening and closing parts to adjust the opening, the valve pressure to maintain a certain , And in the valve body or valve after the injection of cooling water, the medium temperature decreases, this valve is called vacuum valve.


The main components of the gas relief valve are air inlet, handwheel, upper valve cover, upper air chamber, adjusting plug, spring, breathing hole, rubber membrane, outlet, lower valve cover, vacuum chamber, lever, valve Pad, air inlet.

The working principle of gas pressure reducing valve

When the user turns off the switch of the gas appliance, as the liquefied petroleum gas entering the decompression chamber increases, the pressure of the liquefied petroleum gas rises, and the pressure of the liquefied petroleum gas is pressed by the spring Of the rubber film to the top, there is some air in the upper air chamber from the breathing hole discharge valve. In this way, forcing the lever to move up, the use of leverage to close the valve port, cut off the liquefied petroleum gas inlet pathway, pressure relief valve outlet pressure is no longer rising.

When the switch of the gas appliance is opened, the liquefied petroleum gas flows out of the pressure reducing valve, the pressure in the decompression chamber drops, the rubber film is depressed, and the lever is moved downwardly, the external air enters the upper air chamber from the breathing hole, In the move, the intake nozzle becomes larger, the intake air volume increases, the pressure increases. This repeated adjustment process so that the pressure of the decompression chamber is always constant, that is, regardless of the intake pressure is too high or low, the outlet pressure is always stable, and thus until the role of buck and regulator.
