Working principle:
As shown in Figure 7, in the event of a power failure, dynamic iron core 22 is in decline state, and the first valve port 34 is blocked in its lower end, and namely the rubber parts 61 of dynamic iron core 22 lower end blocks the first valve port 34, and at this moment the first valve port 34 is closed; Meanwhile, the elastic force that rubber plug 36 overcomes base spring 37 pushes up downwards by the push rod 8 that descends through of dynamic iron core 22, the upper-end surface of rubber plug 36 and the second valve port 35 is departed from, thus the second valve port 35 is opened.
As shown in Figure 1, when being energized, fixed core 21 and coil form electromagnet and produce electromagnetic force, and the elastic force that dynamic iron core 22 overcomes spring 23 moves upward, thus the lower end surface of iron core 22 and the first valve port 34 are departed from, thus the first valve port 34 is opened; Meanwhile, dynamic iron core 22 moves and makes push rod 8 lose resistance, under the effect of base spring 37, promotion rubber plug 36 and push rod 8 move upward together, until the upper-end surface of rubber plug 36 and the second valve port 35 offset, thus the second valve port 35 are closed.
Open at the first valve port 34, when the second valve port 35 is closed, pressurized air enters in valve chest 3 from suction port 31, then enters in cavity 3a by the first valve port 34, finally flows out from air outlet 33; And after pressurized air enters cavity 3a, open the second valve port 35, close the first valve port 34, pressurized air then can be flowed out from relief opening 32 by the second valve port 35.
When the setting of push rod 8 can ensure that the first valve port 34 is opened, the second valve port 35 is closed, and when the first valve port 34 is closed, the second valve port 35 is opened.
When electromagnetic coil part lost efficacy, manually can control the opening and closing of valve port by switch 5, when with hand by hand switch 5 in valve chest 3 on time, hand switch 5 overcomes hand switch spring 51 resistance and inwardly moves, and by inside it with the offseting to coordinate and will move iron core 22 jack-up of dynamic iron core 22, thus the first valve port 34 is opened; When hand unclamps hand switch 5, hand switch 5 resets under the elastic force effect of hand switch spring 51, and dynamic iron core 22 declines, and the first valve port 34 is closed.
Most preferred embodiment of the present invention is illustrated, and the various change made by those of ordinary skill in the art or remodeling all can not depart from the scope of the present invention.
