Abstract
The utility model discloses a valve which has an improved structure and comprises a valve body, a valve rod, a handle and a valve core. The edge of the connecting position of a valve body and a handle on the valve body is provided with an arc-shaped convex edge; the end of the handle is arranged on the inner side of the arc-shaped convex edge. In addition, a polytetrafluoroethylene retainer ring is arranged between the end of the handle of the valve and the valve body. The utility model effectively improves the sealing performance of the valve rod, and the service life of the valve is extended.
Description
The utility model relates to the ball valve that uses on a kind of valve, particularly water supply pipe.
Need a barrier structure between the valve body of valve and the handle, close fully or opening state to guarantee that valve is in.The barrier structure of common valve is to rely on the elbow of handle end and the plush copper on the valve body to realize.Adopt this structure, handle end can not be close on the valve body, often causes the valve rod place sealability that is connected with handle not good, and leakage phenomenon takes place when reality is used easily, has directly influenced the working life of valve.
The purpose of this utility model is at the problems referred to above, and a kind of valve that improves structure is provided, and effectively improves the sealability at valve rod place.
The purpose of this utility model realizes by following technical proposal: this valve comprises spool, the outer handle and the valve rod that is connected handle and spool of valve body in valve body, the valve body, edge with handle junction on the valve body is provided with the arc convex edge, and the end of handle is positioned at inboard, arc convex edge.This valve has omitted the plush copper on the common valve valve body and the elbow of handle end, is replaced by the arc convex edge on the valve body.This structure can make handle end be close on the valve body.In addition, be provided with the teflon back-up ring between handle end and the valve body.Like this, can effectively improve the sealability at valve rod place.
Below in conjunction with embodiment and accompanying drawing thereof the utility model is elaborated.
Fig. 1 is the schematic representation of the valve that provides of the utility model.
Fig. 2 is the sectional view of Fig. 1 along A-A.
Among the figure, 1, valve body; 2, handle; 3, valve rod; 4, spool; 5, arc convex edge; 6, back-up ring; 7, seal ring; 8, nut.
As shown in the figure, this valve comprises valve body (1), handle (2), valve rod (3) and spool (4).Handle (2) end is positioned at the inboard, arc convex edge (5) on the valve body (1), and is close on the valve body (1).The length of arc convex edge (5) is slightly less than circumference half.Valve rod (3) passes valve body (1) and handle (2), and its outer end is fastening by nut (8).In the present embodiment, valve rod (3) is provided with two rubber seal (7) and a teflon back-up ring (8).Therefore, adopt the valve of this structure can prevent effectively that the leakage phenomenon that valve rod (3) is located from occurring.
Compare with existing valve, the valve that the utility model provides do not increase its manufacturing cost before Put, by the rational modification of structure, sealing property is improved greatly, prolonged the use longevity of valve Life.
Claims (3)
1, a kind of valve that improves structure, comprise spool (4), handle (2) that valve body (1) is located and the valve rod (3) that is connected handle (2) and spool (4) in valve body (1), the valve body (1), it is characterized in that valve body (1) is gone up and the edge of handle (2) joint is provided with arc convex edge (5), the end of handle (2) is positioned at inboard, arc convex edge (5).
2, valve according to claim 1 is characterized in that between described handle (2) end and the valve body (1) teflon back-up ring (6) being arranged.
3, valve according to claim 2 is characterized in that described valve rod (3) is provided with two rubber seal (7) and a teflon back-up ring (6).
