The reason for the top bending of the valve stem of fluorine lined DC globe valve

       Fluorine lined DC globe valve It is a common fluorine lined valve, with a plug shaped valve disc as the opening and closing component, and a flat or conical sealing surface. The valve disc moves in a straight line along the centerline of the fluid. The movement forms of the valve stem of fluorine lined DC globe valve include lifting rod type and lifting rotating rod type. The difference between fluorine lined DC globe valve and other fluorine lined valves is that it is only suitable for fully open and fully closed, and cannot be used for regulation and throttling.
Fluorine lined DC globe valve belongs to the forced sealing type valve, so when the valve is closed, pressure must be applied to the valve disc to force the sealing surface not to leak. When the medium enters the valve from below the valve disc, the resistance that the operating force needs to overcome is the frictional force between the valve stem and packing and the thrust generated by the pressure of the medium. The force to close the valve is greater than the force to open it, so Fluorine lined DC globe valve The diameter of the valve should be large, otherwise the valve stem may bend at the top.
