Description

Technical Field

[0001] The utility model relates to the technical field of valves, in particular to a flow regulating valve. Background Art

[0002] A valve is a device used to control the direction, pressure, and flow of a fluid in a fluid system. It is a control component in a pipeline fluid delivery system. It can be used to control the flow of various types of fluids, such as air, water, steam, various corrosive media, mud, oil, etc. It is used to change the cross-section of the passage and the flow direction of the medium, and has functions such as diversion, cutoff, throttling, check, diversion, or overflow pressure relief. The flow regulating valve controls the opening of the valve according to the forward and backward movement of the piston inside the valve body, thereby effectively controlling the flow, pressure, etc.

Due to the lack of a corresponding clearing mechanism, when impurities in the fluid clog the water outlet, the regulating effect of the flow regulating valve on the fluid will deteriorate, and the flow regulating valve may even lose its flow regulating function.
