Media aplikasi dan kondisi kerja katup kupu-kupu

Katup kupu-kuputerutama digunakan untuk cairan, gas tekanan rendah pipa berdiameter besar. Sangat cocok untuk kesempatan di mana persyaratan kehilangan tekanan tidak tinggi, regulasi aliran diperlukan, dan persyaratan pembukaan dan penutupan cepat; Umumnya suhu di bawah 300 „ƒ dan tekanan di bawah 40 kg). Medium umumnya digunakan untuk air dan gas, dan kebutuhan medium tidak tinggi. Media granular juga dapat digunakan.

1) Media yangkatup kupu-kupudapat mengangkut dan mengontrol air, kondensat, sirkulasi air, limbah, air laut, udara, gas, gas alam cair, bubuk kering, bubur, bubur buah dan campuran dengan padatan tersuspensi.
2) Biasanya, dalam throttling, mengatur kontrol dan media lumpur, panjang struktur pendek dan kecepatan pembukaan dan penutupan cepat (1 / 4 putaran) diperlukan. Cut-off tekanan rendah (perbedaan tekanan rendah),katup kupu-kupudirekomendasikan.
3) Katup kupu-kupu 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 katup kupu-kupu is used under special working conditions, such as throttling regulation, strict sealing requirement, severe wear and low temperature (cryogenic), the special katup kupu-kupu with special designed metal sealing belt regulating device, tri eccentric or Bi eccentric, shall be used.
5) Soft seal eccentric katup kupu-kupu 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 katup kupu-kupu 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 katup kupu-kupu 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 katup kupu-kupu 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 ℃.
