バタフライバルブの塗布媒体と作動条件

2021-05-27

バタフライバルブ主に液体、気体の低圧大口径パイプラインに使用されます。これは、圧力損失の要件が高くなく、流量調整が必要であり、開閉要件が速い場合に適しています。一般的に、温度は300°未満で、圧力は40kg未満です。媒体は一般的に水とガスに使用され、媒体の要件は高くありません。粒状媒体も使用できます。

1)そのメディアバタフライバルブ輸送および制御できるのは、水、凝縮水、循環水、下水、海水、空気、ガス、液化天然ガス、乾燥粉末、スラリー、フルーツスラリー、および懸濁固形物との混合物です。
2)通常、絞り、調整制御、泥媒体では、構造物の長さが短く、開閉速度が速い(1/4回転)必要があります。低圧カットオフ(低圧差)、バタフライバルブがおすすめ。
3) バタフライバルブ can be used in double position adjustment, necking channel, low noise, cavitation and gasification, a small amount of leakage to the atmosphere and abrasive medium.
4) When the バタフライバルブ is used under special working conditions, such as throttling regulation, strict sealing requirement, severe wear and low temperature (cryogenic), the special バタフライバルブ with special designed metal sealing belt regulating device, tri eccentric or Bi eccentric, shall be used.
5) Soft seal eccentric バタフライバルブ is suitable for bidirectional opening and closing and adjustment of ventilation and dust removal pipeline, and is widely used in gas pipeline and water channel of metallurgy, light industry, electric power and petrochemical system.
6) Metal to metal wire sealed double eccentric バタフライバルブ is suitable for urban heating, gas supply, water supply and other gas, oil, acid and alkali pipelines, as a regulating and throttling device.
7) Metal to metal face sealed triple eccentric バタフライバルブ is not only used as program control valve of large PSA gas separation unit, but also widely used in petroleum, petrochemical, chemical, metallurgical, electric power and other fields. It is a good substitute for gate valve and stop valve.

MST バタフライバルブ is suitable for fresh water, sewage, sea water, salt water, steam, natural gas, food, medicine, oil, various acid and alkali and other pipelines which require complete sealing, zero leakage in gas test, high service lie and working temperature from - 10 ℃ to 150 ℃.
