Pneumatic British Fluorine Lined/EPDM Lined Diaphragm Valve Introduction
Vavu yoyang'anira pisitoni ya pneumatic piston imapangidwa ndi valavu ya diaphragm ndi pneumatic actuator.Iwo amagwiritsa wothinikizidwa mpweya monga mphamvu kulamulira otaya madzimadzi sing'anga mu ndondomeko payipi.
Chifukwa cha kapangidwe ka valavu yokhala ndi zingwe zosagwirizana ndi dzimbiri komanso ma diaphragm osagwirizana ndi dzimbiri, palibe mawonekedwe a bokosi lotsekera, chinthu choponderezedwa ndi diaphragm zotanuka, ndipo njira yolumikizira thupi la valavu ndi yosalala, kotero valavu ya filimu ya pneumatic diaphragm ili mphamvu yaying'ono yoyipa, kuyenda kwakukulu, Ndi zabwino zopanda kutayikira, zosavuta, zodalirika, chitetezo chamoto ndi kuphulika, chimagwiritsidwa ntchito kwambiri pakuyendetsa kayendedwe ka asidi amphamvu, ma alkali amphamvu, dzimbiri lamphamvu, kukhuthala kwakukulu, mbewu, ulusi, ndi poizoni komanso zosaipitsa media mu mafakitale makina makina.
Kutseka ndi kutsegulira kwa valve ya diaphragm kumazindikiridwa ndi kukakamiza kwa payipi yomwe ikugwira ntchito pa diaphragm ya rabara yolimbikitsidwa.Pamene mpweya woponderezedwa ulowa m'chipinda chowongolera cha valve, diaphragm imakanikiza pansi ndikutseka ndime ya valve.Pamene kukakamiza mu chipinda chowongolera kuthamangitsidwa kumlengalenga kapena paipi yapansi pamtsinje, diaphragm imakwera ndipo njira ya valve imatsegulidwa.Valavu ilibe tsinde la valve, gasket, mpando wolowera, ndi zina zotero, ndipo gawo lokhalo losuntha mumsewu ndi diaphragm, kotero palibe zowonongeka ndi zotsekera, ndipo zimakhala zokhazikika.Mitundu yosiyanasiyana yamapangidwe ndi mawonekedwe owongolera angagwiritsidwe ntchito pazosowa zosiyanasiyana zowongolera madzimadzi.
