进口凸轮球阀Product Description:

The utility model comprises a valve body and a ball, the valve body is provided with an input channel and an output channel, the ball is arranged between the input channel and the output channel, the ball is provided with a connecting channel, the connecting channel runs through the ball, the end of the output channel close to the ball is provided with a valve seat matched with the ball, the upper and lower sides of the valve body are respectively provided with an upper shaft hole and a lower shaft hole, the upper shaft hole is rotatably connected with the upper valve rod, and the lower end of the upper valve rod is eccentrically provided with a cam, The ball is provided with a cam groove corresponding to the cam, and the cam is connected in the cam groove; The lower shaft hole is rotationally connected with the lower valve rod, the upper end of the lower valve rod is provided with a connector, the ball is provided with a connecting groove corresponding to the connector, and the connector is connected in the connecting groove; The upper valve stem and the lower valve stem are arranged coaxially. It effectively reduces the friction between the ball and the valve seat during rotation, reduces the wear of the valve seat and improves the service life of the valve seat.

进口凸轮球阀characteristic:

Ball valve is a commonly used valve. The ball valve relies on the rotation of the internal opening and closing parts (ball) to control the opening and closing of the ball valve. The existing ball valve comprises a valve body and a ball, the valve body is provided with an input channel and an output channel, the ball is rotationally arranged between the input channel and the output channel, the ball is provided with a connecting channel, the connecting channel passes through the ball, the end of the output channel close to the ball is provided with a valve seat matching with the ball, the valve seat is in close contact with the surface of the ball, the valve body is rotationally connected with a valve stem, and the valve stem is connected with the ball, Rotate the valve rod to drive the ball to rotate. When the ball rotates to a certain angle, the connecting channel connects the input channel and the output channel, and the ball valve is open at this time; When the ball continues to rotate for a certain angle, the connecting channel is at a certain angle with the input channel and output channel. At this time, the input channel and output channel are disconnected, and the ball valve is closed. When the ball valve is in use, the ball needs to rotate frequently. Due to the close contact between the valve seat and the ball, there is friction between the ball and the valve seat during rotation, which will cause wear to the valve seat. After the valve seat is worn, the tightness of the valve seat will be reduced, thus reducing the service life of the valve seat.

进口凸轮球阀Principle:

The utility model comprises a valve rod, an outlet part which can be connected with the ball body and the medium, and a guide valve which can be connected with the ball body, an outlet part which can close the medium, and a guide valve which can be connected with the ball body in the valve body cavity, and a guide valve which can close the medium, The conducting part comprises a conducting inlet part, an intermediate through groove and a conducting outlet part which are successively connected and arranged from the medium inlet to the medium outlet. The conducting inlet part is provided with a plurality of parallel and spaced-apart inlet through holes, the conducting outlet part is provided with a plurality of parallel and spaced-apart outlet through holes, and the inner end of the inlet through hole and the inner end of the outlet through hole are connected with the intermediate through groove. When the regulating ball valve is in use, the ball needs to rotate frequently. Due to the close contact between the valve seat and the ball, there is friction between the ball and the valve seat during rotation, which will cause wear to the valve seat. After the valve seat is worn, the tightness of the valve seat will be reduced, so as to reduce the service life of the valve seat.
