Abstract

PURPOSE:To inhibit introduction of the outside air into a gas breathing valve, by providing a check valve to an exhaust hole of the gas breathing valve and providing a mechanism urging the check valve to open upward. CONSTITUTION:A stopper pin 11, preventing a check valve unit 10 from detaching upward, is mounted to a bolt 5, and the check valve unit 10 is moved rocking about the pin 11 as the supporting point, then a mechanism 12, urging the check valve unit 10 to open upward with the valve in an open state, is provided. Accordingly, the check valve unit 10 holds the opening state, if rapid reduction of pressure is temporarily caused in a closed space, the check valve unit 10 closes a large contoured exhaust hole A by action of negative pressure overcoming the urging mechanism 12, in this way, the outside air can be prevented from introduction into a gas breathing valve.
