522 cannot circumferentially rotate and can only make along its axial direction the reciprocating motion of rectilinear path around center axis thereof, avoid adjusting
Screw rod 522 generates biggish torque in the case where the rotation of nut set 521 drives and causes to sprain damage to pipeline valve 7, reduces and adjusts
Save reliability and accuracy that screw rod 522 adjusts control to pipeline valve 7.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Made any modifications, equivalent replacements, and improvements etc., should be included in the utility model within the spirit and principle of utility model
Protection scope within.
