Abstract
The utility model provides a structure is prevented changeing by valve rod, including fixed connection on the valve rod the guide block and carry out spacing valve support to the guide block, the guide block comprises guide block body and guide block lid, be equipped with the draw -in groove on the guide block body, plane phase butt through machine tooling formation on the both sides face of draw -in groove and the valve rod, the back was fixed with the guide block lid through the fastener on the valve rod was installed to the guide block body, valve support symmetry sets up in the valve rod both sides, be equipped with bellied direction muscle on the valve support, the guide block clamps in the middle of the direction muscle, the both sides face of feasible direction muscle and the mutual butt of the both sides facial features of guide block. The beneficial effects of the utility model are that: split type guide block structure is convenient for install, has reduced workman's intensity of labour, the guide block clamps the structure in direction plane and plane contact in the middle of the muscle and between the two, on the one hand with reduced sliding friction power to reduced the operation torque, on the other hand need not reduce manufacturing cost through the machine tooling milling flutes.
Description
Art
The utility model relates to a kind of valve, and what be specifically related to is the valve rod rotation prevention structure of stop valve, screw down nonreturn valve.
Background technique
The rotation-preventing mechanism of current existing stop valve, carry out anti-rotation by guide pad being arranged guiding groove (Fig. 1), its drawback is: guiding groove has three faces contact with guiding rib, force of sliding friction is large, causes valve operation torque to increase, and due to guide pad will carry out machining groove milling, manufacture cost is high, in addition, difficulty installed by guide pad, increases labor strength.
Model utility content
In order to overcome the above-mentioned shortcoming of existing rotation prevention structure, the utility model provides a kind of valve operation torque little, easy for installation, and the rotation prevention structure that manufacture cost is lower.
The utility model solves the technological scheme that its technical problem adopts, a kind of valve rod rotation prevention structure, comprise the guide pad that is fixedly connected on valve rod and spacing valve rack is carried out to guide pad, guide pad is made up of guide pad body and guide pad lid, guide pad body is provided with draw-in groove, the plane that the bi-side of draw-in groove and valve rod are formed by machining abuts against, guide pad body is installed to after on valve rod and is fixed by fastening piece and guide pad lid, valve rack is symmetricly set on valve rod both sides, valve rack is provided with protruding guiding rib, guide pad is installed in the middle of guiding rib, the bi-side of guiding rib are abutted mutually with the bi-side of guide pad.
The beneficial effects of the utility model are: split type guide block structure is convenient to install, and reduces the labor intensity of workman; Guide pad to be installed in the middle of guiding rib and the structure of plane and plane contact between the two, and one side, compared with existing rotation prevention structure, decreases area of contact, reduce force of sliding friction, thus reduce operation torque, on the other hand, need not machining groove milling be passed through, reduce manufacture cost.
