According to its functions, it can be divided into shut-off valves, check valves, regulating valves, etc. A valve is a control component in a fluid transportation system, with functions such as cut-off, regulation, diversion, prevention of backflow, pressure stabilization, flow splitting, or overflow pressure relief. Valves used in fluid control systems range from the simplest stop valves to various valves used in extremely complex automatic control systems, and their varieties and specifications are quite numerous.

[0003] Valves have many limitations in use. When used in special situations, it is necessary to sample the inside of the pipe to detect water quality or other liquids. For example, a multi-functional sampling valve with the publication number CN217003334U is provided with a threaded rod, a rotating part, a rotating block, a plug rod, and a triangular plate. When sampling the water quality in the water pipe, by rotating the rotating part, the threaded rod and the threaded block are in threaded cooperation, so that the threaded rod moves downward. After moving, it drives the plug rod to rotate and cooperate to pull downward.
