Background technique
At present, the open and close of some valve are to utilize the lifting of valve rod to control on the market, such as gate valve or stop valve etc.; And the lifting of existing gate valve or stop valve is screw thread by being arranged on valve rod one end and the threaded engagement in the valve operating mechanism axle sleeve, and realizes the lifting or the decline of valve rod by the rotation of operating device; Owing to adopt worm structure, the surface friction drag of threaded stem and sleeve thread is bigger when valve rod rises or descend, and for the valve that is used on large-scale petroleum, the chemical pipeline, the moment of torsion when it opens and closes is bigger, the workman is more painstaking when operation, is difficult for opening or closing; As adopt the open and close of automation control valve, because moment of torsion is relatively large, then higher to the power requirements of stepper motor, thereby improve its corresponding cost.
Summary of the invention
Bigger in order to solve existing valve rod its moment of torsion in the process of lifting, the workman operates painstakingly, technical problem such as cause valve to be difficult for unlatching or to close; The utility model provides a kind of valve rod lifting device that is used for valve, and it is reasonable in design, and is simple in structure, can effectively reduce the operation moment of torsion of valve rod when rising or descend.
For solving above technical problem, the technological scheme that the utility model is taked is a kind of valve rod lifting device that is used for valve, it includes the operating device of valve rod and actuate valve stem lifting, described operating device is installed in the support of valve, described operating device includes bearing, axle sleeve, the driver part that is nested with on valve rod, and described axle sleeve one end is nested with in bearing; It is characterized in that the end that described valve rod matches with operating device is that taenidium is shaft-like, the corresponding ball that is provided with in the described axle sleeve, described ball roll to lead with the helical screw formation of valve rod and cooperate.
Further, be provided with a spacer in the described axle sleeve, this spacer is dismountable to be fixed in the axle sleeve; Axially both sides are provided with many group through holes on described spacer, and the distance of described through hole between up and down is complementary with the flight lead of valve rod screw mandrel; Described ball is installed in the through hole of the axial both sides of spacer, and this through hole is provided with a plane of inclination near valve rod one side, and the sphere of this plane of inclination and ball is suitable and ball is limited in the through hole.
Further, described axle sleeve includes Upper shaft sleeve and Lower shaft sleeve, and described Lower shaft sleeve one end is connected in the bearing and with bearing and rotates synchronously, and the other end and Upper shaft sleeve are fixedly connected; Described spacer is arranged in the Upper shaft sleeve and with Upper shaft sleeve fixedlys connected.
The beneficial effects of the utility model are to change the screw thread in valve rod and the axle sleeve into screw mandrel and ball, adopt the screw mandrel roll structure, the surface friction drag of valve rod and operating device reduces greatly, and the operational torque of valve rod also descends thereupon, so not only makes things convenient for the open and close of valve; Simultaneously, when adopting automation control, also can effectively reduce power requirements, save corresponding cost stepper motor.
