Abstract
The invention discloses an anti-rotation structure of a stop valve, which comprises a valve body, a valve clack, a key and a valve rod, wherein the valve body is provided with a valve cavity, the key is fixed on the valve clack, the valve clack and the key are arranged in the valve cavity of the valve body, the valve clack is provided with a T-shaped groove, the valve rod is provided with a T-shaped head, and the T-shaped head is arranged in the T-shaped groove. The invention can meet the use requirement of the stop valve with small caliber in the medium of the pipeline, effectively achieves the aims of opening and closing the valve and preventing the valve clack from rotating by adopting the valve rod, reliably ensures the use of the valve and prolongs the service life of the valve.
Description
Technical field
The present invention relates to a kind of rotation prevention structure, particularly a kind of rotation prevention structure of stop valve.
Background technique
In tube equipment,, generally need to adopt small-bore stop valve for a kind of small-bore pipeline control fed sheet of a media.During switch, the valve rod of stop valve is annotated the motion that receives medium make rotary lifting movement, particularly valve and is washed away, and flap can rotate, and can influence stem packing sealing and flap working life, and the valve switch number of times has seldom just damaged sometimes.In actual tube equipment uses,, satisfy usage requirement, can increase cost like this through the frequent change valve.
Summary of the invention
Technical problem to be solved by this invention provides a kind of rotation prevention structure of stop valve; It can satisfy small-bore stop valve and in pipeline medium, use; Adopt valve rod effectively to reach the switch and the purpose that prevents that flap from rotating of valve, guarantee that reliably valve uses, improve valve working life.
For solveing the technical problem, the invention provides a kind of rotation prevention structure of stop valve, it is characterized in that; It comprises valve body, flap, key, valve rod, and valve body has valve pocket, and key is fixed on the flap; Flap and key are installed in the valve pocket of valve body; Flap has T type groove, and valve rod has T-shape head, and T-shape head is installed in the T type groove.
Positive progressive effect of the present invention is: when the flap that the present invention has broken away from traditional stop valve rotates in valve pocket and valve rod is done the design of rotation and lifting, the present invention is simple and reasonable, and during the valve rod elevating movement, flap does not rotate in valve pocket, and valve rod does not rotate.And the present invention can satisfy small-bore stop valve and in pipeline medium, use, and adopts valve rod effectively to reach the switch and the purpose that prevents that flap from rotating of valve, guarantees that reliably valve uses, and improves valve working life.
Description of drawings
Fig. 1 is the structural representation of the rotation prevention structure of stop valve of the present invention.
Fig. 2 is the structural representation of flap among the present invention.
Fig. 3 is the structural representation of valve rod among the present invention.
Embodiment
Lift a preferred embodiment below, and combine accompanying drawing to come the clearer the present invention that intactly explains.
As depicted in figs. 1 and 2; The rotation prevention structure of stop valve of the present invention comprises valve body 1, flap 2, key 3, valve rod 4, and valve body 1 has valve pocket 11, and key 3 is fixed on the flap 2; Flap 2 is formed the flap assembly with key 3; Flap 2 is installed in the valve pocket 11 of valve body 1 with key 3, and wherein key 3 is resisted against the interior restriction of inner chamber groove flap 2 11 rotations in valve pocket of valve body 1, and the leading role that moves up and down.
As shown in Figure 2, flap 2 has T type groove 21.As shown in Figure 3, valve rod 4 has T-shape head 41, and T-shape head 41 is installed in the T type groove 21 of flap 2, and two side planes of the bottom en shape of T-shape head 41 are resisted against interior two side planes of T type groove 21 respectively with the switch of valve, and the restriction valve rod rotates.
During the valve switch of whole assembling, can guarantee that valve rod does elevating movement, can prevent that again flap from rotating in cavity, be highly suitable for the design and the manufacturing of stop valve, and can satisfy the operating mode usage requirement.Do elevating movement when the operating valve lever screw thread makes valve rod, close or during Open valve, can guarantee that flap does not rotate, the working life that has prolonged valve with satisfied the stop valve SOR.
Though more than described embodiment of the present invention, it will be understood by those of skill in the art that these only illustrate, under the prerequisite that does not deviate from principle of the present invention and essence, can make numerous variations or modification to these mode of executions.Therefore, protection scope of the present invention is limited appended claims.
