Medium aplikasi dan keadaan kerja injap rama-rama

Injap rama-ramadigunakan terutamanya untuk saluran paip cecair berdiameter besar dengan tekanan rendah gas. Ini sesuai untuk keadaan di mana persyaratan kehilangan tekanan tidak tinggi, peraturan aliran diperlukan, dan syarat pembukaan dan penutupan cepat; Secara amnya, suhu di bawah 300 â ƒ dan tekanan di bawah 40 kg). Medium umumnya digunakan untuk air dan gas, dan keperluan mediumnya tidak tinggi. Medium berbutir juga boleh digunakan.

1) Media yanginjap rama-ramaboleh mengangkut dan dikendalikan adalah air, kondensat, air beredar, kumbahan, air laut, udara, gas, gas asli cair, serbuk kering, buburan, buburan buah dan campuran dengan pepejal terampai.
2) Biasanya, dalam pendikit, mengatur kawalan dan medium lumpur, panjang struktur pendek dan kelajuan pembukaan dan penutupan pantas (1/4 putaran) diperlukan. Pemotongan tekanan rendah (perbezaan tekanan rendah),injap rama-ramadisyorkan.
3) Injap rama-rama 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 injap rama-rama is used under special working conditions, such as throttling regulation, strict sealing requirement, severe wear and low temperature (cryogenic), the special injap rama-rama with special designed metal sealing belt regulating device, tri eccentric or Bi eccentric, shall be used.
5) Soft seal eccentric injap rama-rama 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 injap rama-rama 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 injap rama-rama 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 injap rama-rama 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 ℃.
