Drėgio vožtuvo naudojimo terpė ir darbinė būklė

2021-05-27

Drugelio vožtuvasdaugiausia naudojamas skystiems, mažo slėgio didelio skersmens vamzdynams. Jis tinka tiems atvejams, kai slėgio nuostolių reikalavimas nėra didelis, reikalingas srauto reguliavimas, o atidarymo ir uždarymo reikalavimai yra greiti; Paprastai temperatūra yra žemesnė nei 300 ° C ir slėgis yra mažesnis nei 40 kg). Terpė paprastai naudojama vandeniui ir dujoms, o terpės poreikis nėra didelis. Taip pat galima naudoti granuliuotą terpę.

1) Žiniasklaida, kuridrugelio vožtuvasgali transportuoti ir kontroliuoti vandenį, kondensatą, cirkuliuojantį vandenį, nuotekas, jūros vandenį, orą, dujas, skystas gamtines dujas, sausus miltelius, srutas, vaisių srutas ir mišinį su suspenduotomis kietosiomis dalelėmis.
2) Paprastai droseliavimo, reguliavimo valdymo ir purvo terpės atveju reikalingas trumpas konstrukcijos ilgis ir greitas atidarymo ir uždarymo greitis (1/4 posūkis). Žemo slėgio riba (mažas slėgio skirtumas),drugelio vožtuvasrekomenduojama.
3) Drugelio vožtuvas 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 drugelio vožtuvas is used under special working conditions, such as throttling regulation, strict sealing requirement, severe wear and low temperature (cryogenic), the special drugelio vožtuvas with special designed metal sealing belt regulating device, tri eccentric or Bi eccentric, shall be used.
5) Soft seal eccentric drugelio vožtuvas 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 drugelio vožtuvas 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 drugelio vožtuvas 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 drugelio vožtuvas 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 ℃.
