Application medium at kondisyon ng pagtatrabaho ng butterfly balbula

Balbula ng butterflypangunahin na ginagamit para sa likido, gas mababang presyon malaking diameter pipeline. Ito ay angkop para sa mga okasyon kung saan ang kinakailangan sa pagkawala ng presyon ay hindi mataas, kinakailangan ang regulasyon ng daloy, at ang pagbubukas at pagsara ng mga kinakailangan ay mabilis; Pangkalahatan, ang temperatura ay mas mababa sa 300 â „ƒ at ang presyon ay mas mababa sa 40 kg). Ang daluyan ay karaniwang ginagamit para sa tubig at gas, at ang daluyan na kinakailangan ay hindi mataas. Maaari ring magamit ang granular medium.

1) Ang media nabutterfly balbulamaaaring magdala at makontrol ang tubig, condensate, nagpapalipat-lipat na tubig, dumi sa alkantarilya, tubig dagat, hangin, gas, likidong natural gas, dry powder, slurry, fruit slurry at pinaghalong may mga nasuspindeng solido.
2) Karaniwan, sa throttling, kinokontrol ang kontrol at daluyan ng putik, kinakailangan ang maikling haba ng istraktura at mabilis na pagbubukas at bilis ng pagsara (1/4 na pagliko). Mababang pagputol ng presyon (mababang pagkakaiba sa presyon),butterfly balbulaInirerekomenda.
3) Balbula ng butterfly 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 butterfly balbula is used under special working conditions, such as throttling regulation, strict sealing requirement, severe wear and low temperature (cryogenic), the special butterfly balbula with special designed metal sealing belt regulating device, tri eccentric or Bi eccentric, shall be used.
5) Soft seal eccentric butterfly balbula 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 butterfly balbula 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 butterfly balbula 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 butterfly balbula 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 ℃.
