Further inject, adjacent joint sleeve sets up respectively on two relative sides of end main part, and its beneficial part lies in that, such setting can increase the telescopic interval of adjacent joint on the same side of multi-functional bull, can avoid the joint sleeve to cause the condition of interfering with the outside fixing bolt of valve rod.

Further inject, 3 the nominal diameter of joint sleeve increases gradually from the one end of end main part to the torque rod tip, and its beneficial effect lies in, the quick selection to the joint sleeve of operating personnel when carrying out valve rod torque detection of being convenient for.

Further defined, the nominal diameters of the 3 said clamping sleeves are DN20, DN25 and DN40 respectively from one end of the head body to the end of the torque rod.

Further inject, be equipped with the telescopic nominal diameter sign of joint on the side of end main part, its beneficial effect lies in, the telescopic selection of joint of operating personnel of being convenient for.

The utility model has the following technical effects:

(1) through set up a plurality of joint logical grooves that correspond with the valve rod on multi-functional end, can make this device carry out moment to the valve rod of a plurality of different models and detect. (2) The clamping sleeve corresponding to the clamping through groove is arranged on the outer side of the clamping through groove, so that the distance between the multifunctional end head and the fixing bolt at the outer side end of the valve rod can be increased, and the possibility of interference is reduced. (3) This multi-functional moment detection device's simple structure, the practicality is strong, has promoted the efficiency to valve rod detection.
