Three-way, four-way and multi-way valves are multi-way switching valves, which are mainly used for switching and distributing materials and for merging and splitting. Jiepei Valve has designed a three-way ball valve with adjustable flow splitting and confluence for the cooling system of large ships. Installed on the roof of coke oven and other places, the working environment is dusty, there is open flame, and it is easy to splash water.
The three-way ball valve can be divided into T-type three-way and L-type three-way according to the structure. The four-seat three-way ball valve adopts a top-mounted ball. Because the four-seat structure has better sealing performance, the size of the valve cavity inside the ball is correspondingly increased, and the structure is relatively quite complicated.
L-type three-way ball valve (Q44 type) is used to switch the flow direction of the medium in the pipeline, which can connect two vertical pipelines, T-type three-way ball valve (Q45 type) is used for the diversion, merging and flow direction switching of the medium, T-type ball The channel can make the three channels communicate with each other or two of them, and the T-shaped ball valve can realize two of them, one kind, or a certain function.
