In a preferred embodiment, the left and right sides of the valve body are integrally provided with connecting flanges.
Through above-mentioned technical scheme, the valve of being convenient for is connected with the pipeline.
In a preferred embodiment, the valve body is cast from carbon steel.
In a preferred embodiment, a sealing ring matched with the valve plate is fixedly arranged on the inner wall of one side of the valve body.
Through the technical scheme, the sealing performance of the valve is improved.
In summary, due to the adoption of the technical scheme, the beneficial effects of the utility model are as follows: the utility model provides a high-sealing ball valve.
1. When the ball valve is used, the valve core is driven to rotate through the operation shaft, the valve plate on one side of the valve core seals the valve body, and the valve plate is used for sealing, so that the valve core and the valve body do not need to be contacted, abrasion cannot be generated after the ball valve is used for a long time, and the sealing property of the ball valve is improved.
2. The valve core adopts a hemispherical structure, so that the resistance of the valve core in fluid is greatly reduced, and the valve is convenient to open and close.
