[0002] The regulating valve, also known as the control valve, is an executive component in the automatic control and regulation system and is widely used in modern industrial production. The existing regulating valve still has the disadvantage of being inconvenient to disassemble and install. During use, the regulating valve and the pipeline are generally connected by flanges and threads. If there is a leak at the connection end, the bolts will rust and corrode inside the threads over time.

[0003] The existing patent (publication number: CN217603454U) proposes a regulating valve, including a regulating valve body, a stabilizing component, and a connecting piece; an electric actuator is provided on the regulating valve body, and a pair of flanges are provided on both sides of the regulating valve body, a connecting port is provided at the bottom of the regulating valve body, the stabilizing component is provided at the bottom of the flange, the connecting piece is installed in the connecting port, a No. 1 vent is provided in the connecting piece, an exhaust bottle is rotatably connected to the bottom of the connecting piece, a No. 2 vent is provided on the top of the exhaust bottle, a plurality of No. 1 rubber blocks are provided at the bottom of the exhaust bottle, a connecting column is provided on the No. 1 rubber block, a spring is provided on the connecting column, a No. 2 rubber block is provided on the upper part of the connecting column, and a baffle is provided on the plurality of No. 2 rubber blocks.

The problem with this solution is that its connection method is still fixed by flange bolts, which will inevitably leak over time, causing the bolts to be corroded in the flange and eventually become inconvenient to disassemble. Therefore, we propose a regulating valve to solve the above problem. Utility Model Content
