Corrosion-Resistant Direct-Flow Fluorine-Lined Stop Valve

Stop Valve Description

The stop valve is a forced sealing valve, so when the valve is closed, pressure must be applied to the disc to force the sealing surface not to leak. When the medium enters the valve from the bottom of the valve disc, the resistance that the operating force needs to overcome is the friction force between the valve stem and the packing and the thrust generated by the pressure of the medium. The force to close the valve is greater than the force to open the valve, so the valve stem The diameter of the valve must be large, otherwise the failure of the valve stem to bend will occur. After the emergence of self-sealing valves, the flow direction of the medium of the globe valve is changed to enter the valve chamber from the top of the disc. At this time, under the action of the medium pressure, the force to close the valve is small, but the force to open the valve is large, and the diameter of the valve stem can be adjusted accordingly reduced.
