According to the nominal pressure:
| (1) Vacuum valve: refers to a valve whose working pressure is lower than the standard atmospheric pressure. |
| (2) Low pressure valve: refers to the valve with a nominal pressure PN ≤ 1.6Mpa. |
| (3) Medium pressure valve: refers to valves with nominal pressure PN of 2.5Mpa, 4.0Mpa, 6.4Mpa. |
| (4) High-pressure valve: refers to the valve whose nominal pressure PN is 10.0Mpa～80.0Mpa. |
| (5) Ultra-high pressure valve: refers to a valve with a nominal pressure PN≥100.0Mpa. |
Valve
Valves are pipeline accessories used to open and close pipelines, control flow, adjust and control the parameters (temperature, pressure and flow) of the conveying medium. According to its function, it can be divided into shut-off valve, check valve, regulating valve and so on.
The valve can be controlled by a variety of transmission methods, such as manual, electric, hydraulic, pneumatic, turbine, electromagnetic, electromagnetic hydraulic, electro-hydraulic, pneumatic-hydraulic, spur gear, bevel gear drive, etc.; it can be driven by pressure and temperature.
Under the action of other forms of sensing signals, it will act according to the predetermined requirements, or simply open or close without relying on the sensing signals.
The valve relies on the drive or automatic mechanism to make the opening and closing parts lift, slide, swing or rotate Movement, thereby changing the size of the flow channel area to achieve its control function.
Ball valve
1, Ball valve, a valve in which the opening and closing parts (ball) are driven by the valve stem and rotate around the axis of the ball valve. It can also be used for fluid adjustment and control. The hard-sealed V-shaped ball valve has a strong shear force between the V-shaped core and the metal seat of the hard alloy overlay, which is especially suitable for fibers and small solid particles. And other media.
2, The multi-way ball valve can not only flexibly control the confluence, divergence, and flow direction switching of the medium in the pipeline, but also close any channel and connect the other two channels.
3, This type of valve should generally be installed horizontally in the pipeline.
4, According to the driving mode, the ball valve is divided into: pneumatic ball valve, electric ball valve, manual ball valve.
5, The ball valve is mainly used to cut off, distribute and change the flow direction of the medium in the pipeline. It only needs to rotate 90 degrees and a small torque to close tightly.
6, The ball valve is most suitable for use as a switch and shut-off valve, V-shaped ball valve. In addition to paying attention to the pipeline parameters, electric valves should also pay special attention to the environmental conditions in which they are used. Since the electric device in the electric valve is an electromechanical device, its use status is greatly affected by its use environment.
