Abstract

PURPOSE: To completely shut off the backfire when occurring the backfire and exactly prevent the explosion by integrally assembling a check valve unit for shutting off the gas flow passage by the high pressure of the backfire and a flame extinguisher with the body of a gas pressure regulator.
CONSTITUTION: Gas is normally introduced from an entrance passage 6 through a rear portion of a cylinder 5 and the supply passage 9 in a valve casing 7 to push a check valve 12 to open it into an insertion chamber 14 and sequentially through a hole 15, a guide chamber 1i, a flame extinguishing filter 20 and an exhaust passage 19. When a backfire occurs during welding work or the like, it is extinguished during passage of the filter 20, and the valve 12 is closed by the high pressure introduced into the chamber 14. Further, the valve casing 7 is urged backwardly to allow the safety port 10 to urge against a spring 11 so that the casing 7 is moved backwardly to shut off the gas due to the contact between the shut- off valve 8a and the valve seat 8b.
