Normal pressure state, in the raw, the inlet and outlet of valve body are by diaphragm seal for diaphragm；And valve outlet and vacuum dirt collecting tank connect
It connects, diaphragm is pulled together with valve body under the action of negative pressure, and fluid cannot pass through；In solenoid valves, generating negative pressure will
Diaphragm adsorbs upwards, and is close to valve deck, and the inlet and outlet of valve body are opened, and fluid is drawn through under the action of negative pressure.This is specially
When in use, one side diaphragm needs to be close to the inlet and outlet of valve body in nature benefit, in its natural state not due to diaphragm
It can not be fitted closely completely between stress, and the inlet and outlet of valve body, segment fluid flow is caused still can to pass through, thus cannot be real
Existing accurate discharge；On the other hand, which needs for valve outlet to connect with vacuum plant, in the effect of the negative pressure of vacuum plant
Under, it is attracted diaphragm and valve body, so that fluid cannot pass through；Therefore the diaphragm valve of the patent is not applied for making in atmospheric unit
With, in atmospheric unit since negative pressure cannot be generated, can not be by diaphragm adsorption in the inlet and outlet of valve body, therefore cannot be used for
The accurate blanking of aqueous feed solution under normal pressure controls.
