Meán iarratais agus riocht oibre na comhla féileacán

2021-05-27

Comhla féileacánúsáidtear go príomha le haghaidh píblíne mór-trastomhais leachta, gáis. Tá sé oiriúnach do na hócáidí nuair nach bhfuil an riachtanas caillteanais brú ard, tá gá le rialáil sreafa, agus tá na riachtanais oscailte agus dúnta tapa; De ghnáth, bíonn an teocht faoi bhun 300 â „ƒ agus tá an brú faoi bhun 40 kg). Úsáidtear an meán go ginearálta le haghaidh uisce agus gáis, agus níl an riachtanas meánach ard. Is féidir meán gráinneach a úsáid freisin.

1) Na meáin gocomhla féileacánin ann uisce, comhdhlúthán, uisce a scaiptear, séarachas, uisce farraige, aer, gás, gás nádúrtha leachtach, púdar tirim, sciodar, sciodar torthaí agus meascán le solaid ar fuaidreamh a iompar agus a rialú.
2) De ghnáth, le linn throttling, rialáil agus meán láibe, is gá fad struchtúir ghairid agus luas oscailte agus dúnta tapa (1/4 cas). Scoite le brú íseal (difríocht brú íseal),comhla féileacánmoltar.
3) Comhla féileacán 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 comhla féileacán is used under special working conditions, such as throttling regulation, strict sealing requirement, severe wear and low temperature (cryogenic), the special comhla féileacán with special designed metal sealing belt regulating device, tri eccentric or Bi eccentric, shall be used.
5) Soft seal eccentric comhla féileacán 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 comhla féileacán 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 comhla féileacán 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 comhla féileacán 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 ℃.
