shut-off valve, stop valve factory, cut-off valve factory
The opening and closing valve ( stop valve / globe valve ) is a plug-shaped valve flap, the sealing surface is flat or conical, and the valve flap moves linearly along the centerline of the fluid. The valve stem is in the form of a lifting rod (the stem moves up and down, the hand wheel does not lift), and there is also a lifting and rotating rod type (the hand wheel rotates and lifts together with the valve stem, and the nut is arranged on the valve body). Shut-off valves are only suitable for full opening and full closing and do not allow adjustments and throttling.
Globe valves have the following advantages:
1 , simple structure, manufacturing and maintenance more convenient.
2 , the work schedule is small, opening and closing time is short.
3 , good sealing, low friction between the sealing surface, long life.
For the installation and maintenance of globe valves, please note the following:
1. The shut-off valve operated by handwheel and handle can be installed at any position of the pipeline.
2. Hand wheel, handle and transmission mechanism are not allowed to be lifted.
3 , the direction of flow of the medium should be consistent with the direction of the arrow shown in the body.
