Abstract
The utility model provides a kind of ball screw plate valve, comprise valve body, tail-hood, valve gap, valve rod and handwheel, handwheel connects valve rod by ball screw pair, the lower end of valve rod is connected with flashboard, ball screw pair comprises ball screw and feed screw nut, the lower end of ball screw is connected with valve rod, ball screw is arranged on bearing nut by feed screw nut, bearing nut is fixed on valve gap by bearing support, flashboard lower end is provided with balance foot piece, the lower end of balance foot piece is placed in tail-hood, and tail-hood is fixed on the bottom of valve gap by bolt and nut.Transmission efficiency is high, valve switch moment is little, can equilibrium valve cavity pressure, well solves ball screw automatic rotation, problem that self-locking performance is low.
Description
Technical field
The utility model relates to technical field of petroleum machinery, is specifically related to a kind of ball screw plate valve.
Background technique
In the flap type that current oil field is conventional, the movement of valve plate is that the rotation relying on valve rod realizes, and the connection of valve rod and valve plate, valve rod and Stem Mut and transmission rely on screw thread, because the surface of contact of screw thread is large, transmission efficiency is low, therefore the switch moment of valve is large, and the opening and closing of valve are required great effort very much, particularly high pressure, bigbore valve.
Model utility content
Technical problem to be solved in the utility model overcomes defect of the prior art, a kind of ball screw plate valve is provided, there is transmission efficiency high, the feature that switch moment is little, in order to solve, ball screw self-locking performance is low, the problem of automatic rotation, arranges a balance foot piece at valve plate afterbody.
For solving the problems of the technologies described above, the utility model provides a kind of ball screw plate valve, comprise valve body, tail-hood, valve gap, valve rod and handwheel, handwheel connects valve rod by ball screw pair, the lower end of valve rod is connected with flashboard, ball screw pair comprises ball screw and feed screw nut, the lower end of ball screw is connected with valve rod, ball screw is arranged on bearing nut by feed screw nut, bearing nut is fixed on valve gap by bearing support, flashboard lower end is provided with balance foot piece, the lower end of balance foot piece is placed in tail-hood, tail-hood is fixed on the bottom of valve gap by bolt and nut.
As further improvement of the utility model, the underpart of tail-hood is provided with foot piece safety cover.
The beneficial effect that the utility model reaches is: adopt ball-screw-transmission, transmission efficiency is high, valve switch moment is little, and valve plate afterbody is provided with balance foot piece, can equilibrium valve cavity pressure, well solves ball screw automatic rotation, problem that self-locking performance is low.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.Following examples only for clearly the technical solution of the utility model being described, and can not limit protection domain of the present utility model with this.
As shown in the figure, the utility model provides a kind of ball screw plate valve, comprise valve body 4, tail-hood 2, valve gap 6, valve rod 7 and handwheel 12, handwheel 12 connects valve rod 7 by ball screw pair, the lower end of valve rod 7 is connected with flashboard 5, ball screw pair comprises ball screw 11 and feed screw nut 10, the lower end of ball screw 11 is connected with valve rod 7, ball screw 11 is arranged on bearing nut 9 by feed screw nut 10, bearing nut 9 is fixed on valve gap 6 by bearing support 8, flashboard 5 lower end is provided with balance foot piece 3, balance foot piece 3 and valve rod 7 constitute the active force that a pair force balance face act on two bars and cancel out each other, valve plate is in stress balance state, avoid the phenomenon of valve automatic rotation, ensure production safety, the lower end of balance foot piece 3 is placed in tail-hood 2, tail-hood 2 is fixed on the bottom of valve body 4 by bolt and nut, foot piece safety cover 1 is provided with in the underpart of tail-hood 2, in order to protection balance foot piece 3.Handwheel 12 is moved by ball screw pair band ovable valve stem 7, realizes folding and the closedown of valve.
Only preferred implementation of the present utility model described in upper; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model know-why; can also make some improvement and distortion, these improve and distortion also should be considered as protection domain of the present utility model.
