The valve rod is connected with two-seater valve element through upper end cover and valve body, and the two-seater valve element is located in valve pocket, the valve pocket with described
Two-seater valve element is provided with one group of through hole, and being respectively arranged on the left side and the right side for the valve body flows into valve body and flow out valve body.
As the further restriction of the technical program, in the inflow valve body and the outflow valve body, pressure sensing is provided with
Device, the pressure sensor are connected with controller, and the controller connects the servomotor and cylinder.
Used as the further restriction of the technical program, the valve body is connected by bolt with the upper end cover and the bottom end cover
Connect.
As the further restriction of the technical program, in the inflow valve body and the outflow valve body, inclined-plane passage is provided with.
Advantage of the present utility model and good effect are：Using two-seater valve element and valve pocket, the passage after change valve element simultaneously will
Partial pressure is conducted directly to valve element rear and carrys out negative function power, and the active force of generation is offset so that pressure medium increase will not
Impact is produced on controlled valve torsion again, the requirement to actuator is effectively reduced, product cost and type selecting difficulty has been saved；
The through hole arranged on two-seater valve element and valve pocket can open its folding condition of side, through-hole alignment, valve pocket by the rotation of servomotor
Connect with valve body, can be with smaller portions pressure, the active force needed for significantly more efficient reduction actuator；Flow out valve body and flow into valve
Internal pressure sensor can be by the pressure feedback of medium in passage to controller, and controller control YE makes phase
To reaction, adjust automatically is realized；Inclined-plane passage can effectively reduce direct impact of the medium to valve body, protect valve body, increase valve
The service life of body.
