Dynamic screw mandrel is persistently rotated, and the anti-torque produced by the tangential friction force on the now moment of torsion provided by filler and valve rod is equivalent,
Valve rod is moved along a straight line with valve element.When valve rod and valve core movement to open extreme position when, its linear motion is obstructed, now by flower
The second clutch that key and drive lead screw are attached just with first clutch automatic buckling；When therefore, electric operator is carried
For moment of torsion more than the tangential moment of torsion produced by filler, so drive lead screw will pass through second clutch and first clutch drives
Valve rod and valve element are rotated, and the action form of valve is converted to angle stroke by Direct Travel.The wear-resisting lining being located on gland
Set and fairlead and guide ring installed in valve inner can be that valve rod and valve element provide double up and down guiding so that valve has excellent
Good dynamic stability., with valve element in Direct Travel motor process, medium washes water or anti-fouling agent are by installed in valve for valve rod
Circular flow channel mouth on parts casing pipe, flows through runner mouth circular on valve rod, into the spiral fan shaped groove on valve element and punching in vivo
Hole flushing.As extension elongation of the valve rod with valve 3 is continued to increase, medium injection angle gradually expands, flushing water or anti-fouling agent from
Spiral fan shaped groove and flushing hole are ejected.Valve rod 8 can make the screw fan on valve element with valve element during the stroke motion of angle
Shape groove and flushing hole form spherical injection, and polymeric kettle is uniformly cleaned or is coated with.During valve closing, second clutch with
First clutch is rapidly separated, now the moment of torsion produced by filler and the anti-torque produced by the tangential friction force on valve body etc.
Value, valve rod are directly converted to Direct Travel motion by angle stroke motion with valve element.When valve rod with valve core movement to closing extreme position
When, the soft or hard double sealing structure adopted between valve body and valve element can meet VI grade of sealing class requirement.
