Abstract
A kind of ball valve with rotation prevention structure, comprise valve body, valve body is made up of left valve barrel and right valve barrel, and sphere installation is between left valve barrel and right valve barrel, and spheroid upper end has connecting groove, valve rod lower end is provided with connected element, connected element inserts in connecting groove, and valve rod is fixedly connected with spheroid, and the side of connected element is provided with boss, on spheroid, the side of connecting groove is provided with groove, and boss is inlayed and is arranged in groove.The beneficial effects of the utility model are: the boss on the flat tenon structure in valve rod lower end matches with the groove in the connecting groove of spheroid upper end, effectively avoid spheroid also to have rotation at x axle direction in the process of rotating around y axle, the sealability that has ensured valve, has extended working life.
Description
Technical field
The utility model relates to a kind of ball valve, particularly a kind ofly under the operating mode of high pound level, prevents the ball valve that spheroid rotates on non-opening direction.
Background technique
In existing high pound level floating ball valve, valve rod lower end is provided with flat tenon structure, in the groove of valve rod by flat tenon insertion spheroid upper end, is fixedly connected with spheroid.But the flat tenon of valve rod lower end is circular arc, the groove of spheroid upper end is arc groove, in use, in the time that pressure rating reaches Class4500 pound, spheroid can have angular turn on x axle direction, and then can destroy the sealability of valve, shorten working life, causes the waste of resource.
Model utility content
In order to overcome the above-mentioned shortcoming of existing ball valve, the utility model provides a kind of knot can effectively ensure that valve rod and spheroid rotate on same axis, and the ball valve with rotation prevention structure not rotating in the other direction.
The utility model solves the technological scheme that its technical problem adopts, a kind of ball valve with rotation prevention structure, comprise valve body, valve body is made up of left valve barrel and right valve barrel, sphere installation is between left valve barrel and right valve barrel, left valve barrel is fixedly connected with by fixed component with right valve barrel, spheroid upper end has connecting groove, valve rod lower end is provided with connected element, connected element inserts in connecting groove, and valve rod is fixedly connected with spheroid, and the side of connected element is provided with boss, on spheroid, the side of connecting groove is provided with groove, and boss is inlayed and is arranged in groove.
Connected element is flat tenon structure.
The beneficial effects of the utility model are: valve rod lower end is flat tenon structure, on flat tenon structure, be provided with boss, groove in the connecting groove of boss and spheroid upper end matches, effectively avoid spheroid also to have rotation at x axle direction in the process of rotating around y axle, the sealability that has ensured valve, has extended working life.
Brief description of the drawings
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is embodiment's structural representation;
Fig. 2 is the connection diagram of parts 1 and parts 4 in Fig. 1;
Fig. 3 is E-E sectional view in Fig. 2.
In figure: 1. valve rod; 2. flat tenon structure; 3. connecting groove; 4. spheroid; 5. boss; 6. groove; 7. left valve barrel; 8. right valve barrel.
Embodiment
As shown in Figure 1, 2, 3, a kind of ball valve with rotation prevention structure, comprise valve body, valve body is made up of left valve barrel 7 and right valve barrel 8, spheroid 4 is arranged between left valve barrel 7 and right valve barrel 8, left valve barrel 7 is bolted to connection with right valve barrel 8, spheroid 4 upper ends have connecting groove 3, valve rod lower end is provided with flat tenon structure 2, flat tenon structure 2 inserts in connecting groove 3, and valve rod 1 is fixedly connected with spheroid 4, and the side of flat tenon structure 2 is provided with boss 5, on spheroid 4, the side of connecting groove 3 is provided with groove 6, and boss 5 is inlayed and is arranged in groove 6.
Under high pound level operating mode, in the time of valve opening and closing, when valve rod 1 is in the time that y axle direction rotates, spheroid 4 keeps and valve rod 1 coaxial rotation, has avoided the rotation of spheroid 4 on x axle direction, has ensured the sealing of valve.
Claims (2)
1. the ball valve with rotation prevention structure, comprise valve body, valve body is made up of left valve barrel and right valve barrel, sphere installation is between left valve barrel and right valve barrel, left valve barrel is fixedly connected with by fixed component with right valve barrel, spheroid upper end has connecting groove, valve rod lower end is provided with connected element, connected element inserts in connecting groove, valve rod is fixedly connected with spheroid, it is characterized in that: the side of described connected element is provided with boss, on described spheroid, the side of connecting groove is provided with groove, and described boss is inlayed and is arranged in described groove.
