advantages
Fluorine globe valve has the following advantages:
Simple structure, manufacturing and maintenance easier.

Working travel small, open time is short.

Good sealing, sealing surface friction between the small, the life is long.

Fluorine globe valve faults are as follows:

Fluid resistance is big, open and closed necessary force is bigger.

Apply to with particles, viscosity of bigger, easy coked medium.

Regulation performance is poor.

High-pressure globe valve type according to stem threads location points have outer thread type, threaded type. According to the flow of medium cent, have straight-through type, injector and horny type. Globe valves according to seal form cent, have packing seal globe valves and bellows seal globe valves.

note
Fluorine globe valve installation and maintenance should notice the following matters:

Handwheel and handles globe valve can be installed in the pipeline of any position.

The handwheel, the handle and wei dynamic organization, don't allow for hookon use.

Medium flow should be shown with the valve body arrow direction.

Leong abundant cut-off valve, also called JieMen, is the most widely used a valve, it was popular, is due to open and close process between the sealing surface friction small, more durable, open height is not big, make easy, convenient maintenance, not only suitable for medium-voltage, but also suitable for high pressure. It closed principle is, valves on poles pressure, make clapper sealing surfaces and seat sealing tightly 6-colours, prevent medium circulation.

Globe valves only medium one-way flow, install directional from time to tome. Its structure length is more than gate valves, and fluid resistance big long-term operation, sealing dependability is not strong.

Globe valve is divided into three categories: straightway, orthogonal type and injector inclined globe valves.
