Gas Overflow Safety Protector

Abstract

A gas overflow safety protector comprises a main body including a longitudinal passage for gas; a gas overflow protecting valve disposed in the inlet of the longitudinal passage, which keeps opened under a normal gas pressure and keeps closed under an abnormal gas pressure of overflow; wherein said gas overflow protecting valve including: a valve body including a longitudinal through hole, said longitudinal through hole including a larger-diameter portion as an inlet and a smaller-diameter portion as an outlet, and at least part of the inner wall of said larger-diameter portion being made from magnetic material; a valve core, being a ball made by magnetizer, movably disposed in said larger-diameter portion of the longitudinal through hole for opening or closing said smaller-diameter portion. Compared with the prior art, the gas overflow safety protector of the present invention does not include a spring element. The ball-shaped valve core and the magnetic material on the larger-diameter portion cooperate each other through magnetism so as to protect under the gas overflow. The gas overflow safety protector of the present invention has long usage time, and can be long used in the high temperature, and the structure is simple too.
