Throttle valve The plug-in one-way throttle valve is a device used to regulate fluid flow, which can realize one-way flow and control the flow. The throttle valve has a simple structure and usually consists of a valve body and a valve core. The valve body has an inlet and an outlet, and the spool can move inside the body to adjust the flow by changing the position of the spool. The working principle of the plug-in one-way throttle valve is to change the passage area of the fluid through the valve body through the movement of the valve core, so as to control the flow. When the spool moves in one direction, the channel area decreases, the fluid flow is hindered, and the flow rate decreases; while when the spool moves in the other direction, the channel area increases, the fluid flow is hindered by a decrease, and the flow rate decreases. Increase. The plug-in one-way throttle valve has the advantages of simple structure, high reliability, and convenient installation, and is widel…
