Abstract

An electromagnetic zone control valve for a high-pressure water mist extinguishing system comprises a valve body (1), a main valve seat (2), a main spool (3), a spring A (4), a bonnet (5), an emergency spool (6), an emergency operating rod (7), an armature sleeve (9), an electromagnetic armature (10), a pilot spool (11) and a spring B (12). The electromagnetic zone control valve has the advantage that the problems that the existing zone control valve is prone to mistaken opening, long in opening time, and prone to failure and leakage in repeated opening and closing are solved.

Description

technical field [0001] The invention relates to the field of fire-fighting equipment, in particular to an electromagnetic partition control valve of a high-pressure water mist fire extinguishing system. Background technique [0002] The existing water mist partition control valves have low rated working pressures of 2.5Mpa, 6.3Mpa, and 12Mpa; material: copper alloy, strength angle. [0003] The current fine water mist partition control valves include: electric ball valves with AC220V working power supply, solenoid valves, and hydraulic decompression driven partition valves. Water pressure fluctuations during normal start / stop operation of the water mist system stabilized pump and water pressure surge when the main high-pressure fire pump starts often cause the hydraulic decompression type partition control valve to accidentally open the water, resulting in accidental losses; AC220V is adopted Power-controlled products have potential safety hazards of electric shock; after u...
