Cross connecting pipe 221 and 16 exits valve body of valve channel outlet 12.After pressure reduction in the second cavity 28, secondary diaphragm 23 by
To pressure imbalance and overcome under the driving of pressure the elastic force of second spring 25 to act on to move up, lead to the first intercommunicating pore
222 and connecting pipe 221 form access, the high pressure gas in the first cavity 13 passes sequentially through the first intercommunicating pore 222 and connecting tube
Road 221 is discharged from valve outlet 12.At this point, pressure imbalance that primary diaphragm 14 is subject to and overcoming under the driving of pressure
The elastic force effect of one spring 15 moves up, so that valve body import 11 be made to be connected to valve outlet 12, valve is opened.The solenoid valve
Using second level guide structure, so that the power acted in dynamic iron core 275 is reduced, since dynamic iron core 275 is driven by coil 271
, therefore, the power consumption of coil 271 also reduces, and is finally reached the purpose for reducing energy consumption.Since the diameter of pilot hole 261 is only
0.15mm~0.25mm, coil 271 power consumption P=0.3W, pulsewidth 10ms, single motion power consumption 0.17x10-8Degree adds up movement
596000000 consumption kilowatt-hours, energy-saving effect are excellent.
Referring to Fig. 2, the entrance of first intercommunicating pore 222 is equipped with the first filter screen 224.First filter screen 224
Effect is impurity screening, prevents impurity from entering in the second cavity 28.
Referring to Fig. 2, the bottom surface of the diaphragm upper cover 26 is equipped with the second filter screen 264.The effect of second filter screen 264
It is impurity screening, prevents impurity from entering in pilot hole 261 by the second intercommunicating pore 262.
