Abstract
The utility model discloses an anti-rotation structure of a stop valve, comprising a valve body, a valve flap, a key and a valve rod, wherein the valve body is provided with a valve chamber, the key is fixed on the valve flap, the valve flap and the key are installed in the valve chamber of the valve body, the valve flap is provided with a T-shaped groove, and the valve rod is provided with a T-shaped head installed in the T-shaped groove. With the anti-rotation structure, the requirement of using the stop valve with small caliber in media in a pipeline can be met, and the purposes of opening or closing the valve can be achieved effectively and the valve flap is prevented from being rotated by adopting the valve rod, thus reliably ensuring the application of the valve and prolonging the service life.
Description
Technical field
The utility model 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 is subjected to 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 by the frequent valve of changing.
The model utility content
Technical problem to be solved in the utility model provides a kind of rotation prevention structure of stop valve, it can satisfy small-bore stop valve and use in pipeline medium, adopt valve rod effectively to reach the switch of valve and prevent the purpose that flap rotates, guarantee that reliably valve uses, improve valve working life.
For solveing the technical problem, the utility model 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 utility model is: when the flap that the utility model has been broken away from traditional stop valve rotates in valve pocket and valve rod is done the design of rotation and lifting, the utility model is simple and reasonable, during the valve rod elevating movement, flap does not rotate in valve pocket, and valve rod does not rotate.And the utility model can satisfy small-bore stop valve to be used in pipeline medium, adopts valve rod effectively to reach the switch of valve and prevents the purpose that flap rotates, and 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 the utility model stop valve.
Fig. 2 is the structural representation of flap in the utility model.
Fig. 3 is the structural representation of valve rod in the utility model.
Embodiment
Lift a preferred embodiment below, and come the clearer the utility model that intactly illustrates in conjunction with the accompanying drawings.
As depicted in figs. 1 and 2, the rotation prevention structure of the utility model stop valve comprises valve body 1, flap 2, key 3, valve rod 4, valve body 1 has valve pocket 11, key 3 is fixed on the flap 2, flap 2 and key 3 are formed the flap assembly, flap 2 and key 3 are installed in the valve pocket 11 of valve body 1, and wherein key 3 is resisted against that restriction flap 2 rotates in the inner chamber groove of valve body 1 in valve pocket 11, 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, prolonged the working life of valve and satisfied the stop valve SOR.
Though more than described embodiment of the present utility model, but those skilled in the art is to be understood that, these only illustrate, and under the prerequisite that does not deviate from principle of the present utility model and essence, can make numerous variations or modification to these mode of executions.Therefore, protection domain of the present utility model is limited by appended claims.
