Description

Technical Field

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

[0002] The regulating valve is also called a flow regulating valve or a pressure regulating valve. The flow regulating valve is intuitive and easy to use. It can intuitively adjust and control the flow. The flow regulating valve is widely used. When in use, its two ends are usually connected to the pipeline through flanges. When the flanges are butt-jointed and installed, a plurality of bolts are required to be used for fixing between the two flanges.

[0003] At present, when the flow regulating valve is installed using flanges, the installation of multiple groups of bolts is relatively cumbersome, and the connection between the bolts and nuts is prone to rust and corrosion, which is not convenient for the quick positioning installation and disassembly of the regulating valve. For this reason, we propose a regulating valve with a positioning structure to solve the above problems. Summary of the Utility Model
