[0002] At present, the structural principle of ball valves is that a sphere with a circular through hole is used as the opening and closing part. The sphere rotates around the center line of the valve body with the valve stem to realize the opening and closing of the valve. Ball valves are mainly used in pipelines to cut off, distribute and change the flow direction of the medium. It can be closed tightly with just a 90-degree rotation and a very small torque. Due to the structural advantages of ball valves, they can be widely used in occasions such as petroleum, chemical industry, steel smelting, etc. where corrosive fluid media are transported. However, the existing three-way ball valves require tools for installation and need to be sealed with raw tape after installation, which is relatively cumbersome. Therefore, a T-type three-way ball valve that can be connected quickly and easily while ensuring sealing is proposed to solve the above problems. Utility Model Content
