Background art:

valves are plumbing accessories used to open and close a pipe, control flow direction, regulate and control parameters of the transport medium (temperature, pressure and flow). According to their function, they can be classified into shut-off valves, check valves, regulating valves, and the like. The valve is a control part in a fluid conveying system and has the functions of stopping, adjusting, guiding, preventing counter flow, stabilizing pressure, shunting or overflowing and relieving pressure and the like. Valves used in fluid control systems range in variety and size from the simplest shut-off valves to the variety of valves used in extremely complex autonomous systems. The valve can be used for controlling the flow of various types of fluids such as air, water, steam, various corrosive media, slurry, oil products, liquid metal, radioactive media and the like. The valves are classified into cast iron valves, cast steel valves, stainless steel valves, chrome molybdenum vanadium steel valves, dual-phase steel valves, plastic valves, nonstandard valves, and the like according to the material. When the existing valve is used for shunting and converging control, a mode of on-off control is carried out at a single position, the purpose of unified control of all shunting ports cannot be realized, and the use is inconvenient.
