Claims (1)
り筒体内に保持されたボール弁がガスの異常流出
時にガス流れ方向下手側に設けた弁座に接当して
ガス流路を遮断するように構成したガスヒユーズ
であつて、前記ボール弁による遮断部の前後の流
路を連通させるリーク孔を設けたガスヒユーズ。 A ball valve installed in the gas flow path and held in a cylinder by a spring in a balanced state is configured to come into contact with a valve seat provided on the downstream side in the gas flow direction and shut off the gas flow path when gas abnormally flows out. The gas fuse is provided with a leak hole that communicates the flow path before and after the shutoff portion by the ball valve.
