Preferably, the sealing surface is taper.
Preferably, the sealing diaphragm is rubber.
Preferably, the valve rod, through-hole, screw block coaxial line.
Preferably, ring flange is connected on the valve body in the import and exit.
By adopting the above technical scheme, due to the setting of permanent magnetism pedestal and electromagnet, then pass through the magnetic pole of setting permanent magnetism pedestal
With the current direction of electromagnet, the sealing surface for enabling to spool to combine with valve chamber is by the reprimand between electromagnet and permanent magnetism pedestal
Power firmly forces together, achieve the purpose that block import, compared with spring structure, the present invention have it is wear-resistant, by environment shadow
Ring the feature small, performance is stable；The setting of controller can be opened by the size of control electric current, flexibly adjustment section spool
The size for opening pressure facilitates operation；The setting of pressure sensor can intuitively, quickly check the real-time pressure that spool is subject to,
Foundation is provided for the adjusting electric current of controller；What is connect with through hole whorl screws the setting of block, being capable of regulating magnet and permanent magnetism
Gap between pedestal can play the role of the size of adjusting spool cracking pressure according to magnetic force with the principle of distance change,
Retain pressure controlled backup；The setting for sealing diaphragm, movable spool and valve rod are kept apart with medium, have been not only able to
Effect prevents stuck phenomenon, additionally it is possible to play the role of increasing spool and valve base sealing effect.
