It is a device that makes the medium (liquid, gas, powder) in the piping and equipment flow or stops and can control its flow; in modern industry , due to the limitation of the use of space, the two-way valve is often unable to meet the actual needs. Installing a three-way pipe in a narrow space to divert the flow of the main flow, and then installing multiple control valves is not convenient for operating each control valve; the existing two-way In the ball valve technology, multiple two-way stop valves and tee pipes are required to realize the diversion and decompression of the main flow. At the same time, multiple control switches are required to control the opening and closing of the sub-flow. Generally, fixed connection is adopted between the two-way pipes, and the sub-flow pipe interface needs to cooperate with multiple elbows to realize multi-directional diversion. The main flow diversion not only wastes a lot of elbows, but also takes up a lot of space, which is not conducive to the operation and control of the two-way ball valve. The sealing ring of the two-way ball valve is repeatedly squeezed during the opening and closing process, which shortens the service life of the sealing ring and cannot meet the actual needs. Therefore, we need a new type of two-way mechanical valve.
