Product Description

 

Product Description

The opening and closing part of the fluorine lined globe valve is a plug shaped valve disc, with a flat or conical sealing surface.

The valve disc moves in a straight line along the centerline of the fluid. The movement form of the valve stem can be either the lifting rod type (valve stem lifting, handwheel not lifting) or the lifting rotating rod type (handwheel rotates together with the valve stem to lift, and the nut is installed on the valve body). Globe valves are only suitable for full open and full close, and are not allowed to be adjusted or throttled.

Fluorine lined globe valves are mandatory sealed valves, 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 needs to be overcome by the operating force is the friction 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 the valve, so the diameter of the valve stem should be larger, otherwise the failure of the valve stem top bending will occur. After the appearance of self sealing valves, the medium flow direction of the shut-off valve changes from above the valve disc to enter the valve chamber.

At this time, under the action of medium pressure, the force to close the valve is small, while the force to open the valve is large, and the diameter of the valve stem can be correspondingly reduced. 

At the same time, under the action of the medium, this type of valve is also relatively tight. The "three modernizations" of valves in China once stipulated that the flow direction of shut-off valves should be from top to bottom.

The closing principle of a shut-off valve is to rely on the pressure of the valve stem to tightly fit the sealing surface of the valve disc and the sealing surface of the valve seat, preventing the flow of medium.

 

The shut-off valve only allows one-way flow of medium and has directional installation. The structural length of the shut-off valve is larger than that of the gate valve, and the fluid resistance is high. Therefore, the sealing reliability is not strong during long-term operation.
