Micro resistance slowly-closing check pneumatic valve structure characteristics of the micro resistance slowly-closing check pneumatic valve and other check the difference between pneumatic valve

the micro resistance slowly-closing check pneumatic valve is also called the non-return valve, its role is to prevent the backflow medium pipeline. Open-close part by medium flow and power to open or closed, to prevent the backflow medium pneumatic valve check pneumatic valve. Check pneumatic valve belong to automatic pneumatic valve class, mainly used for medium on the one-way flow of pipeline, only allowed to medium flows in one direction, in order to prevent accidents. Apply to clean medium, should not be used for large medium containing solid particles and viscosity.
the micro resistance slowly-closing check pneumatic valve USES:
the micro resistance pneumatic valve is suitable for the nominal pressure slowly-closing check PN. MPa~. MPa、类- - - ； Nominal diameter DN, NPS / ~ ~ mm; Working temperature - ℃ ~ all kinds of piping, used to prevent the backflow medium. By choosing different capable person, can be applied to water, steam, oil, nitric acid, acetic acid, strong oxidizing medium and urea, and other media.

the micro resistance slowly-closing check pneumatic valve features:
the pneumatic valve is mainly composed of pneumatic valve, pneumatic valve cover, valve plate, balance tuo, piston, and adjust the pneumatic valve, pipes for water supply and drainage, installed in the pump outlet to prevent medium counter-current and fire destructive water hammer. With pneumatic disc light, big opening, power saving effect is remarkable, small fluid resistance, water hammer eliminate rational structure, reliable sealing performance, wear resistance, long service life, smooth operation, no vibration, no noise, etc.

the micro resistance slowly-closing check pneumatic valve and other check pneumatic valve
check the difference between a pneumatic valve according to the using environment is different, can be divided into several types, more commonly used include: slowly-closing check pneumatic valve, pneumatic valves, forged steel, stainless steel check check pneumatic valve, flue check pneumatic valve, etc. So slow close check pneumatic valve and other check what is the difference between pneumatic valve? Emphatically introduce below slowly-closing check pneumatic valve pneumatic valve, stainless steel and rubber disc check check the difference between the pneumatic valve:
slowly-closing check the function of the pneumatic valve is to prevent the backflow medium pipeline. It is suitable for the nominal pressure PN. MPa~. MPa、类- - - ； Nominal diameter DN, NPS / ~ ~ mm; Working temperature - ℃ ~ all kinds of piping, used to prevent the backflow medium. By choosing different capable person, can be applied to water, steam, oil, nitric acid, acetic acid, strong oxidizing medium and urea, and other media.
rubber disc check pneumatic valve is made by steel plate, steel bar and reinforced nylon fabric substrate, the outer layer of rubber, pneumatic valve switch can be put into service life time. It adopts full flow area design, with a small head loss, not easy to pile up sundry, simple maintenance and so on characteristics. Mainly suitable for horizontal installation of water supply and drainage systems, can be installed in the pump outlet place, to prevent backflow and water hammer pump damage. Rubber disc check pneumatic valve can be installed in the reservoir in and out of the water pipe on the by-pass pipe, in order to prevent the water back into the water supply system.
stainless steel check pneumatic valve can also be used to give the pressure could rise to more than the main system of auxiliary system supply piping. Stainless steel check pneumatic valve according to different materials, the pipeline can be applied to a variety of media. Due to the change of the fluid velocity in pressure piping pressure jump or fall rise of the hydraulic impact phenomenon.
