Three way ball valves are T-type and L-type. T-type can connect three orthogonal pipelines and cut off the third channel. It plays the role of diversion and confluence. L type can only be connected to each other;
The two pipes. The interconnection of the third pipeline cannot be maintained at the same time, but only plays a distribution role.
Low fluid resistance. The resistance coefficient is equal to that of the pipe section with the same length. The utility model has the advantages of simple structure, small rest area and light weight.
Tight and reliable. At present, the sealing surface of ball valve is widely made of plastic with good sealing performance. It has also been widely used in vacuum systems.
Easy to operate. Quick opening and closing. From full open to full close, it can be controlled remotely as long as it rotates 90 °.
Convenient maintenance. The ball valve has simple structure and the sealing ring is generally movable. Disassembly and replacement are quite convenient.
When fully open or fully closed, the sealing surface of the ball and valve seat is isolated from the medium. When the medium passes through, it will not cause the erosion of the valve sealing surface.
