Solenoid valve is organized for centrifugal fan

The utility model discloses a solenoid valve is organized for centrifugal fan, including first valve body, second valve body, third valve body, first guide's solenoid valve, second guide solenoid valve, third guide solenoid valve, settings of establishing ties in proper order of first valve body, second valve body and third valve body, first guide's solenoid valve, second guide solenoid valve and third guide solenoid valve correspond the connection respectively on first valve body, second valve body and third valve body to correspond control first valve body, second valve body and third valve body break-make respectively. The utility model discloses the series connection of solenoid valve is organized for centrifugal fan through the low discharge valve body realizes the unloading of different flows, need not to design the solenoid valve of multiple different models, adopts a plurality of diaphragm parallel control to correspond the valve body switching, even one of them diaphragm assembly damages, other valve bodies also can continue work, avoids the harm that the air-blower received because of surging.
