Description

Multi-channel independently controlled ocean platform scheduling multi-way valve device Technical Field The invention relates to the field of valve structures, in particular to a multichannel independently controlled ocean platform scheduling multiway valve device. Background The multiway valve is one device for controlling the flow direction of fluid or distributing fluid, and belongs to the field of mechanical engineering and fluid controlling system. It is commonly used in hydraulic systems, pneumatic systems, and chemical equipment to enable switching and flow distribution between multiple lines. One common mode of operation of a multiple-way valve is rotary switching, which type of multiple-way valve is also known as a plug valve. A valve is provided which is opened or closed by rotating a valve plug to open or close a passage opening in the valve plug to or from a passage opening in the valve body. The plug valve works in such a way that the size and direction of the plug passage are changed by rotating the plug, thereby adjusting and cutting off the fluid. The plug valve is easy to adapt to a multi-channel structure, and a plurality of side joints are arranged on the periphery of the valve body, so that the plug valve can be connected with different side joints in a butt joint mode through rotation of the plug.
