Further, be with sleeve on the excircle of second end of valve rod, the internal diameter of sleeve equals the external diameter of the maximum cylindrical of second end of valve rod, and sleeve is fixed on the axle sleeve.
Further, sleeve is provided with the counterweight nut that is used for the balance clamp weight.
Further, sleeve and the distance of counterweight nut by being threaded between the end face of regulating counterweight nut and valve rod second end.
Further, clamping fixture seat is provided with alignment pin, and guide ring and axle sleeve are by the axis rotation location around alignment pin.
Further, the banding device comprises locking nut, and the part of locking nut and first end position that is in valve rod of axle sleeve threaded engagement mutually connects.
Further, the face that contacts with locking nut of resilient sleeve is a taper surface, and the small end of the taper surface of resilient sleeve is nearer from first end of valve rod.
Further, axle sleeve and the coaxial setting of guide ring.
The utility model adopts above structure, has the following advantages:
1, is convenient to the location of valve rod, can improves the part shape precision;
2, be applicable to the valve rod of the multiple different diameters of axle.
