Title: Safety device for inflammable gas
Inventor: IMAI NOBUHIKO
IPC: F23D14/82
Filed: 1980-12-23
Abstract: PURPOSE: To provide a means to instantaneously close a gas inlet port and hold  a valve in securely closed condition even against the oscillating pressure by  utilizing the explosion pressure of a gas when a reverse flow and/or backfire of  a gas occurs.  
     CONSTITUTION: When a reverse flow and/or backfire occurs in a piping, the explosion in the piping rapidly increases the pressure allowing a movable check valve 22 to be pressed against a valve seat 10a of a piston 10 by a spring 26 to close a gas passage 11, and at the same time the said piston is pressed downward by the reverse flow pressure applied to the top of the movable check valve 22 sliding along a cylinder 6 and pressing a main check valve 16 by a pressing member 15 against a valve seat 5 of a gas inlet port 3 while having a piston  ring 12 to reach the position of an engaging shoulder 9 of the cylinder 6, said  piston ring being expanded by its own resilient force and engaging to the said  shoulder 9 thereby securely preventing the reverse flow of the gas.
