Under the action of the positioning pin 3232 and the limiting groove 3233 of the limiting block 3231, the adjusting screw 322 cannot rotate circumferentially around the central axis thereof but can only reciprocate linearly along the axial direction thereof, so that the adjusting screw 322 is prevented from generating large torque under the driving of the rotation of the nut sleeve 321 to cause sprain damage to the pipeline valve 8, and the stability, reliability and accuracy of the adjustment control of the pipeline valve 8 by the adjusting screw 322 are reduced.
The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
