Description
Technical field
The present invention relates to valve technology fields, and in particular to a kind of diaphragm valve and the side using the diaphragm valve trandfer fluid
Method.
Background technique
Diaphragm valve is a kind of valve that opening and closing is realized by the deformation of flexible diaphragm (such as diaphragm of rubber).With cultivation industry
Fast development, it is higher and higher to the requirement intelligently raised, the accurate discharge of feed is controlled in particular for a kind of valve, with
Realize intelligence feeding.But valve in the prior art is bad to aqueous feed solution blanking control effect, can not achieve accurate discharge
And feeding, because it is necessary to study one kind to be suitable for intelligence feeding field, and it is able to satisfy the diaphragm of aqueous feed solution accurate discharge
Valve.
The conveying equipment for fluid substances that Chinese patent CN107747634A discloses a kind of diaphragm valve and is made of the diaphragm valve
And its delivery method, patent valve body, valve deck and the diaphragm, the principle of the patent is: in solenoid valve no power, body cavity is
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.
Summary of the invention

S3, when needing trandfer fluid again, the solenoid valve (1) is powered, and the exhaust outlet (12) of solenoid valve (1) is opened；Through described
The compressed air of air compression system enters from the air inlet (11) of solenoid valve (1), and from the exhaust outlet of solenoid valve (1) (12)
Discharge；Cavity between the valve deck (2) and valve body (4) is normal pressure state, and the diaphragm pad (3) acts in the elastic force of itself
Under, nature is returned to, i.e., the described diaphragm pad (3) imports and exports being spaced apart for (41) with the valve body, i.e., the diaphragm valve is beaten
It opens, fluid can enter valve body (4) discharge port from valve body (4) feed inlet.
