Abstract

Gas supply valve for mounting to vehicle gas cylinders. With a molded valve body It has a hollow body.At the top of the valve body is a handwheel that is used to turn on and off the gas that flows into the gas cylinder, while the central axis below the dial is the transmission axis to move up. -down Inside the upper body of the valve body according to the internal rotation direction of the handwheel Which at the side On one side of the valve body is a cavity with a threaded internal surface for the valve assembly. Safety is used to release the pressure in the gas cylinder while the pressure in the gas cylinder exceeds the limit, and on the other side of the valve body is the gas ejection outlet that will take the gas contained in the cylinder. The gas is released and there is a gas vent and gas outlet that is located on the lower body of the valve body, with the gas vent connected to the outlet for the safety valve assembly. And the gas outlet will Connected to the gas ejection port to take out the gas contained in the gas cylinder. Where the bottom surface The threaded end of the gas outlet is attached to the threaded top end of the gas outlet pipe, the upper and the lower threaded end of the gas outlet pipe fastened to the mechanism. Check valve

Claims (3)

1. Gas supply valve for mounting to vehicle gas cylinders consists of a hollow valve body (1) formed by a hollow body at the top of the valve body (1) as a hand crank.
