Description
Technical field
The present invention relates to a kind of solenoid valve more particularly to a kind of film cushion solenoid valves.
Background technology
Currently, the dedusting mechanism of underground is mainly solenoid valve form, solenoid valve is divided into film pad-type, two kinds through-type.Its
Middle film pad-type uses pilot circuit elder generation venting partial pressure, generates pressure difference between upside on the downside of film pad, is beaten using hydraulic pressure
Film pad is opened, flow is made to be sprayed by drain hole.The dedusting mechanism of such structure is only applicable to low pressure, in high pressure due to film pad
Relatively low be easily torn of intensity leads to product failure.Moreover, if inlet pipeline is thinner in use, film can be caused
Pad cannot be opened completely, and flow hydraulic pressure after film pad-type solenoid valve becomes smaller and cannot spray.Through-type solenoid valve is due to hydraulic pressure
The pressure of generation is larger, if thinking normally to open the aperture that can only reduce drain hole, the straight-through valve sluicing aperture of underground is equal at present
In 5mm hereinafter, causing water yield less, and the sealing not with great difficulty leak in low pressure, seriously reduce the performance of product.
To solve the above-mentioned problems, it is desirable to be able in high and low pressure can normal use, and water yield disclosure satisfy that need
It asks, the structure of good seal performance, but has not been reported in the prior art.
