Abstract
The utility model discloses a wear-resisting ball valve. The wear-resisting ball valve comprises a valve body, a ball body, a valve cover, a valve seat, a valve rod and a handle. The ball body is mounted inside the valve body; the valve seat is arranged between the ball body and the valve body; the valve cover is fixedly mounted on the valve body; the valve rod is arranged inside the valve cover in a penetrating mode, the inner end of the valve rod is fixedly connected with the ball body inside the valve body, and the outer end of the valve rod is connected with the handle; and the inner sealing surface of the valve seat, which is in contact with the ball body, is provided with a wear-resisting gasket with a thickness of 1.5-2.5 cm, and the outer end surface of the valve seat, which abuts against the valve body, is provided with a compression spring. According to the structure above of the wear-resisting ball valve, the inner sealing surface of the valve seat, which is in contact with the ball body, is additionally provided with the wear-resisting gasket, so that the wear-resisting performance of the ball valve is greatly improved, and further the service life of the ball valve is effectively prolonged; and meanwhile, the compression spring is arranged between the valve seat and the valve body, so that the inner sealing surface of the valve seat and the wear-resisting gasket on the inner sealing surface of the valve seat can be guaranteed to be in contact with the ball body all the time, and further the integral sealing performance of the ball valve can be guaranteed.
Description
Technical field
The utility model relates to a kind of ball valve.
Background technique
Ball valve is a kind of valve commonly used, its structure mainly includes valve body, spheroid, valve gap, valve seat, valve rod, handle, spheroid is installed in the valve body, pass through valve base sealing between spheroid and the valve body, in actual applications, because spheroid is in active state all the time, therefore causes inner sealing surface rapid wear contacted with it on the valve seat, and then shortened the working life of ball valve.
Summary of the invention
At the deficiencies in the prior art, the utility model provides a kind of wear resistance ball valve that can effectively increase the service life.
For achieving the above object, the utility model provides a kind of wear resistance ball valve, comprise valve body, spheroid, valve gap, valve seat, valve rod, handle, spheroid is installed in the valve body, valve seat is installed between spheroid and the valve body, valve gap is installed on the valve body, described valve rod is arranged in the valve gap, and the spheroid in the inner of valve rod and the valve body is affixed, the outer end of valve rod is connected with handle, and the contacted inner sealing surface of described valve seat and spheroid is provided with wear-resistant gasket, and the thickness of described wear-resistant gasket is 1.5 ~ 2.5cm, and be provided with the waveform slip-resistant texture with the contacted junction surface of valve seat on the wear-resistant gasket, also be equiped with the compression spring on the exterior edge face that described valve seat and valve body connect.
The beneficial effects of the utility model are: adopt said structure, because the utility model has been set up wear-resistant gasket at described valve seat and the contacted inner sealing surface of spheroid, therefore improved the wear resistance of ball valve greatly, and then prolonged working life of ball valve effectively, the compression spring that arranges between while valve seat and the valve body, can guarantee the valve seat inner sealing surface and on wear-resistant gasket contact with spheroid all the time, thereby guarantee the overall tightness of ball valve.
The utility model can further be set to be provided with bearing and seal ring between described valve rod and the valve gap, and described seal ring is at least 2, and the corresponding axially both sides up and down that are distributed in bearing.
Adopt said structure, set up bearing between valve rod and valve gap, the frictional force of spheroid and valve seat in the time of can reducing ball valve greatly and open and close further prolongs working life of ball valve.
The utility model also can further be set to described valve seat and the contacted inner sealing surface of spheroid is provided with containing groove, described wear-resistant gasket setting-in is gone in the containing groove of described valve seat, also is provided with the positioning groove of ccontaining described compression spring on the exterior edge face that described valve seat and valve body connect.
