Sredstvo za uporabo in delovno stanje dušilnega ventila

Metulj ventilse uporablja predvsem za tekočinske, plinske nizkotlačne cevovode velikega premera. Primeren je za primere, ko zahteve za izgubo tlaka niso velike, potrebna je regulacija pretoka in hitro odpiranje in zapiranje; Na splošno je temperatura pod 300 ° C in tlak pod 40 kg). Medij se običajno uporablja za vodo in plin, potrebe po mediju pa niso velike. Lahko se uporabi tudi zrnat medij.

1) Mediji, kimetulj ventillahko prevažajo in nadzirajo vodo, kondenzat, krožno vodo, kanalizacijo, morsko vodo, zrak, plin, tekoči zemeljski plin, suh prah, brozgo, sadno brozgo in mešanico s suspendiranimi trdnimi snovmi.
2) Običajno je za dušenje, regulacijo krmiljenja in blato potrebno kratko dolžino konstrukcije ter hitro odpiranje in zapiranje (1/4 obrata). Izklop nizkega tlaka (razlika v nizkem tlaku),metulj ventilje priporočljivo.
3) Metulj ventil 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 metulj ventil is used under special working conditions, such as throttling regulation, strict sealing requirement, severe wear and low temperature (cryogenic), the special metulj ventil with special designed metal sealing belt regulating device, tri eccentric or Bi eccentric, shall be used.
5) Soft seal eccentric metulj ventil 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 metulj ventil 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 metulj ventil 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 metulj ventil 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 ℃.
