Abstract

PURPOSE:To minimize an pressure increase required to exceed a blow-off pressure of a safety valve by provideing a permanent magnet together with a compression spring to a valve shaft so that the valve is pressd against a valve seat by means of a compression spring force and an absorbing force of the permanent magnet. CONSTITUTION:A valve 4 is forced by a compression spring 10 so as to normall close an exhaust port 3, and a premanent magnet 7 is provided beneath a spring receptacle 6 accepting a pressing force of the compression spring 10. Since the permanent 7 is absorbed toward a valve housing 2, the valve 4 is ultimately kept pressed against the exhaust port 3 by means of a resultant force of both forces, i.e., a pressing force of the compression spring 10 and an absorbing force of the permanent magnet 7. According to this constitution, when the fluid pressure in the pipe exceeds this resultant force even slightly, the valve 4 is widely opened instantaneously offering an excellent characteristic as a safety valve.
