Low in high pressure pneumatic valve how to differentiate between high pressure pneumatic valve principle

Low in the high-pressure pneumatic valve division:



in the low pressure pneumatic valve is just a general statement, such as the height of the people, fat is no clear distinction, now of the pressure pipe fittings design is specific to pressure value, don't say this place to install a medium pressure pneumatic valves. General with 1. 6MPa、10. 0 mpa as the cut-off point, design pressure is less than or equal to 1. 6 mpa for low pressure pipes, greater than 1. 6 mpa less than or equal to 10. 0 mpa for medium-voltage pipeline, more than 10. 0 mpa for high pressure pipeline.





pressure piping refers to all under internal pressure and external pressure of pipeline, whatever its tube medium.
part of the pneumatic valve pressure can also press this to distinguish.

general according to the grades of high and low pressure can be divided into:


1, the low pressure pipeline engineering pressure < 1. 6MPa；

2, medium pressure pipeline engineering pressure 1. 6 - 6. 4MPa；

3, high pressure pipeline engineering > 10 mpa pressure;









the most current habit is according to the stress and structure types to distinguish. According to the demand of pressure pneumatic valve flange thickness and thickness of the pneumatic valve also is not standard, 6. 4 mpa and 10 mpa flange thickness and thickness of the pneumatic valve body is totally different. Such as: general pneumatic valve is the most basic brake pressure 1. 6 mpa, according to GB/T139272008 and standard JB/T90921999 casting generally selected 1. 6 mpa, disappointing the pressure when the highest is 1. 6 x1。 5 = 2. 4 mpa, if you line pressure exceeds this not line, now a lot of manufacturers in order to save costs, the pneumatic valve did the thin wall, a conventional brake pressure pneumatic valve 1. 6 mpa are a little difficult.


high pressure pneumatic valve principle:


high pressure pneumatic valve is mainly for rigid body material processing and related processing, processing the material becomes after the compression wear-resisting. High pressure technology at present for a lot of pneumatic valve manufacturer is no longer a difficult technology. But in the field of superhigh pressure, those should be frequent supercharging pressure relief system, and is particularly important. Ultrahigh pressure pneumatic valves, was the main failure cause of cavitation and erosion wear, and a lot of factors influencing the cavitation and erosion, the main material mechanics, fluid mechanics performance factors and environmental impact.



in the process of practical application for the application of high pressure pneumatic valve or there are many worthy of our attention, such as whether the material standard, material the use of the maximum pressure. Highly corrosive fluids will reduce the use of pneumatic valve. With medium viscosity or granule can accelerate wear of pneumatic valve, shall be duly follow change. High temperature and high pressure pneumatic valves shall be selected to brand pneumatic valve manufacturer. The new pipeline system should be the right choice of pneumatic valve structure and sealing performance.
