( Patent No.: ZL98211953.4)
There are many important process, the valve working environment is very bad.
For example:
▲In the field of coal chemical industry water gas, coal-bed gas, petrochemical industry exhaust gas containing a large amount of dust, tar or other contaminants. Lead to valve jam and other due to viscous effects and consequences.
▲In many chemical equipment ( such as: polypropylene, polyethylene ), polymer into the compressor resulting in valve jam and other due to viscous effects and consequences.
▲due to excess lubricating oil and condensate into the valve, causing liquid hammer.
Therefore, Wenzhou Jian Qing invented a special valve, able to withstand extreme conditions meet the high performance and reliability.
He was: FW valve ( anti-fouling valve)
Design features:
Wide channel, wide sealing cover, air tightness, flow characteristics, energy saving
The big lift, through flow area, valve loss
High performance impact PEEK valves, valve seat, valve wear a small, low noise
The special valve plate structure design - reducing valve plate rolling motion
Stout spring, low stress, long service life
Antifouling treatment ---- liquid-strike, resistance, oil resistance viscous impurities, is not easy to accumulate, good reliability
Valve cover design - resistant oil viscosity
Field of application:
Coal chemical industry
Petroleum, petrochemical waste gas recovery
FW valve ( anti-fouling valve) was born more than 10 years, solved many practical problems, improve the reliability of the compressor running. Especially to produce coal big country of our country, has great significance.
