Pneumatic quick coupling throttle valve

     Throttle valve is a valve that controls the flow of fluid, mainly used to adjust the flow and pressure of the pipeline medium. By changing the opening of the throttle valve, the flow resistance of the medium can be changed, so as to achieve the adjustment of flow and pressure. Throttle valves are widely used in various industrial pipeline systems, such as petroleum, chemical, electric power, pharmaceutical and other fields. The structure and working principle of the throttle valve are relatively simple. Common throttle valves mainly include body, stem, disc and other components.       During operation, the disc moves up and down inside the body to change the cross-sectional area of the channel, thereby regulating flow and pressure. The throttle valve has the advantages of flexible adjustment, simple structure and convenient operation. However, because the throttle valve has a certain resistance to the fluid medium, it is necessary to pay attentio…
