Embodiment
The following stated is only preferred embodiment of the present utility model, does not therefore limit protection domain of the present utility model.
Embodiment, as shown in Figure 1.
A kind of large discharge direct-acting type often drives solenoid valve used for air compressor, and comprise valve body 1, joint 15 and electromagnetic switch component, joint 15 is arranged at valve body 1 top, and joint 15 is threaded with valve body 1, is provided with O type circle 3 between joint 15 and valve body 1.Electromagnetic switch component is arranged at joint 15 top, and namely valve body 1, joint 15 and electromagnetic switch component form the utility model agent structure.
Valve body 1 forms suction port m, air outlet b and valve port f, suction port m is communicated with air outlet b by valve port f, diaphragm holder 16 is provided with between valve body 1 and joint 15, relief hole c is provided with in the middle part of diaphragm holder 16, diaphragm holder 16 is provided with the valve film 2 matched with described valve port f, valve film 2 is fixedly installed in diaphragm holder 16 by pad 17, and the outer rim of valve film 2 is fixed and is folded between joint 15 and valve body 1, and valve film 2 is provided with throttle orifice d.Form cavity in valve body 1, this cavity is divided into upper chamber e and air-inlet cavity a by valve film 2, and throttle orifice d is communicated with upper chamber e and air-inlet cavity a, plays the effect of pressure reduction between balance upper chamber e and air-inlet cavity a.
Electromagnetic switch component comprises coil carrier g, and the upper end of coil carrier g is connected with hexagon nut 12, and coil carrier g is fixedly connected with joint 15 by guide's headstock 7, and guide's headstock 7 is threaded with joint 15, is provided with O type circle 5 between guide's headstock 7 and joint 15.
