FXYJ-IV machine electric type pressure relief valve

Shanghai million tracks Electrical Technology Co. specializes in producing pressure relief openings, specifically the following models: FXYJ-1 Mechanical type pressure relief openings, FXYJ-2 mechanical type pressure relief openings, FXYJ-3 mechanical type pressure relief openings FXYJ-II electric type vent pressure valve, FXYJ-III electric type pressure relief valve, FXYJ-IV machine electric type pressure relief valve XYK-A pressure relief openings, XYK-B pressure relief openings, SAXD-0.25-J mechanical type pressure relief openings, SAXD-0.12- J Mechanical type pressure relief openings SAXD-0.1 electric type pressure relief valve, SAXD-0.15 electric type pressure relief valve, SAXD-0.25 electric type pressure relief valve vent valve TKC, TKC vent port, YYXYK-B1-type pressure relief openings, YYXYK-A1-type pressure relief openings, YYXYK-A2 type relief 1, classified according to mounting domestic pressure relief opening indoor installation and outdoor installation types. Indoor and outdoor installation and are divided into embedded and wall-mounted and ceiling three structures. 2, according to the startup mode startup mode classification pressure relief openings into a power-type start and no power formula startup types. A power pressure relief port was divided into two startup forms: one is the drive actuator for the pressure sensor and gear reducer micro-motor; the other is the pressure sensor and solenoid start. No power actuator pressure relief port driver, there are three forms: one is the weight structure; a pressure regulator structure; the other is a comprehensive structure. 3, the structure of the pressure relief valve opening (automatic pressure relief device) valve structure, there are three forms: one is the valve has a two-piece or two-piece consisting of more blades, the blades when linked together at an angle of rotation can be achieved when opening and closing; The second is a plate structure, the valve is attached to the valve body in the valve body stretching for some distance to achieve open and close; the third is the cover structure, the valve is mounted on the body frame, body frame and turn it on and around a certain angle off function. Cover type and structure of the plate sealing performance is relatively good.
