Ball valve function
The ball valve is mainly used to cut off, distribute and change the direction of medium flow in the pipeline.
Ball valve not only simple structure, good sealing performance, and in a certain nominal through the range of small volume, light weight, less material consumption, small installation size, and drive torque is small, easy to operate, easy to achieve rapid opening and closing, is one of the fastest development of the valve varieties in recent decades.
Characteristic
1. O ring Second stem seal design.
2.Valve stem explosion-proof device design.
3.Design of large lamellar deformation space.
4.High platform design in line with ISO211 standard.
5.Double – layer butterfly – shaped shrapnel device design.
6.Multilayer v-ring packing, stem seal with zero leakage design.
7.Thrust ring device design.
8.Valve seat fireproof design.
Advantages of ball valve
1.Has the lowest flow resistance (virtually zero).
2. It can be used reliably in corrosive media and low boiling liquids because it is not stuck at work (in the absence of lubricants).
3.Complete sealing can be achieved in the range of larger pressure and temperature.
4.Ball in position to close the case automatically positioning.
5. The work of the media in the two-sided reliable seal.
6.Compact structure and light weight, it can be considered as the most reasonable valve structure for low temperature medium system.
7.Body symmetry, especially when welding body structure, can well withstand the stress from the pipeline.
