Model utility content
The purpose of this utility model is: the ball valve providing a kind of improvement, and it can impurity scratch seal ring in anti-fluid, extends working life.
The utility model is achieved in that a kind of ball valve of improvement, comprise valve body, valve rod, seal ring and valve ball, described valve body has liquid inlet pipe point-blank, valve ball chamber and drain pipe, valve stem passage is communicated with valve ball chamber, the linear vertical at the axis of valve stem passage and liquid inlet pipe, valve ball chamber and drain pipe place; Described seal ring tool spherical inner chamber, is positioned at seal ring both sides and the vertical cavity of the liquid entering hole communicated with spherical inner chamber and liquid outlet and through seal ring; Seal ring is arranged in valve ball chamber, and the spherical inner chamber of valve ball and seal ring rotates joins and liquid sealing; Its special way is: also comprise anti-wiper, and described anti-wiper is separately positioned on liquid inlet pipe and drain pipe and intersection, valve ball chamber;
Anti-wiper comprises the cavity of sphere curved surface and the passage along axis;
Sphere curved surface and the ball surface of described anti-wiper are rotatably assorted, and the passage of anti-wiper is communicated with drain pipe with liquid inlet pipe respectively.
The ball valve of described a kind of improvement, its special way is: described anti-wiper is provided with interface;
Described cavity and valve ball are rotatably assorted, and the interface of an anti-wiper is connected with liquid inlet pipe, and the interface of another anti-wiper is connected with drain pipe.
The ball valve of described a kind of improvement, its special way is: described liquid inlet pipe be communicated with drain pipe to have inner joint with intersection, valve ball chamber and be positioned at inner joint fall level;
The interface of described anti-wiper inserts in inner joint, and the end face of anti-wiper coordinates stop bit with step.
The ball valve of described a kind of improvement, its special way is: described valve ball chamber, drain pipe and valve stem passage is one-body molded makes, and the connection side of described valve ball chamber and liquid inlet pipe has internal thread interface, and the end face of internal thread interface has seal groove;
Described liquid inlet pipe has external screw joint, and liquid inlet pipe is threaded with valve ball chamber, the ellipsoidal cross section of the seal ring in seal groove.
The ball valve of a kind of improvement of the utility model; owing to adopting such structure; the liquid-through hole of valve ball and liquid inlet pipe and drain pipe point-blank time be water conservancy diversion state; when valve ball rotates; anti-wiper, by the liquid stripper in ball surface, can prevent liquid and impurity from entering between valve ball and seal ring effectively, thus protection seal ring; keep sealability, increase the service life.
