FIELD: mechanical engineering. ^ SUBSTANCE: invention relates to safety valves and it is designed for preventing destruction of working reservoirs under action of excess gauge pressure. Proposed safety valve has housing with intake and outlet holes, spring-loaded cup, breakable element made of easily melting material and heating element. Valve is provided with insert with ring groove. Said insert engages with rod. Breakable element is installed between insert and bottom of spring-loaded cup. Heating element is located around breakable element on outer surface of housing and is connected to supply source through thermal relay. Holes are made in base of insert. Second end of spring interacts with ball through seal. Said ball closes inlet hole. ^ EFFECT: improved reliability of operation of safety valve, provision of safety at operation with aggressive gases in emergency situations. ^ 2 dwg |
