Oil operated Throttle Valve

The working principle of the hydraulic throttle valve is as follows:   Structural compositionThe hydraulic throttle valve is mainly composed of a valve body, a valve core, a valve seat, a hydraulic cylinder, a piston, a valve stem and a valve position transmitter. The valve core is usually cylindrical and made of hard alloy as a whole; the inner ring of the valve seat is also inlaid with hard alloy; the valve cover and the medium contact end are welded with hard alloy, which has good wear resistance and corrosion resistance. A nylon wear-resistant bushing is embedded in the outlet channel of the valve to protect the valve body from wear.Working processHydraulic drive: The tail of the valve cover is a hydraulic cylinder and a piston. The piston is driven by hydraulic oil to drive the valve stem, and then the valve core is driven forward and backward.Throttling control: The forward and backward movement of the valve core changes the flow area between the valve core and the valve sea…
