Many people who know cars should know CNG Regulator, but there are still many people who do not know CNG Regulator or have never heard of CNG Regulator. Today we will talk about the principle of the CNG Regulator.

When the regulator leaves the factory, the adjusting spring is in an uncompressed state. At this time, the main valve disc and the auxiliary valve disc are in a closed state. When using, turn the adjusting screw clockwise to compress the adjustment spring to move the diaphragm against the auxiliary valve disc. The medium is A hole enters above the piston through the auxiliary valve seat to the b hole. Under the action of the medium pressure, the piston moves downward to push the main valve disc to leave the main valve seat, so that the medium flows to the back of the valve. At the same time, the chole enters below the diaphragm, when the valve When the rear pressure exceeds the set pressure, the diaphragm is pushed up to move the compression adjustment spring, and the auxiliary valve disc moves in the closing direction, so that the medium flowing into the upper part of the piston is reduced, and the pressure also drops. At this time, the main valve disc is in the main valve. The force of the disc spring moves up and down so that the gap between the main disc and the main valve seat is reduced, and the flow of the medium is also reduced so that the pressure after the valve also drops to a new balance. On the contrary, when the pressure after the valve is lower than When setting the pressure, the gap between the main valve disc and the main valve seat increases, and the medium flow rate also increases, so that the pressure after the valve also increases to a new balance.
