Pneumatic British Diaphragm Valve

Pneumatic British Fluorine Lined/EPDM Lined Diaphragm Valve Introduction

Ko te piston piston diaphragm regulating valve he mea tito he diaphragm valve me te pneumatic actuator.Ka whakamahia te hau kōpeke hei mana ki te whakahaere i te rere o te reo wē i roto i te pipeline tukanga.

Na te hanganga o te tinana takirere me te arai-atete me te diaphragm-atete ki te waikura, kaore he hanganga pouaka whakakii, ko te huānga throttle he diaphragm rapa, a he maeneene te awa rere o te tinana takirere, no reira kua whai iti kaha kino, rere nui, Ki nga painga o te kore leakage, haratau, pono, ahi me te pahūtanga tiaki, kua whakamahia whānuitia i roto i te tikanga rere o waikawa kaha, alkalis kaha, waikura kaha, pokey teitei, witi, muka, me te paitini me pāpāho kore-pohaehae i roto i ngā pūnaha aunoatanga ahumahi.

Ko te katinga me te whakatuwheratanga o te puera diaphragm ka kitea e te pehanga mai i te pipeline e mahi ana i runga i te diaphragm rapa whakakaha.Ka kuhu te reo pehanga ki roto i te ruma whakahaere o te takirere, ka pehi te diaphragm ki raro, ka kati i te ara takirere.Ka tukuna te pehanga i roto i te ruma whakahaere ki te hau, ki te paipa o raro ranei, ka piki te diaphragm, ka whakatuwherahia te huarahi takirere.Karekau he kakau takirere, peeke, nohoanga noho, me era atu, ko te waahanga neke noa o te hongere ko te diaphragm, na reira kaore he waikura me te raka, he nui ake te pumau.He maha nga momo hanganga me nga puka whakahaere ka taea te tono ki nga momo hiahia whakahaere wai.
