Olona phawu lubalaseleyo kukuba i-diaphragm yahlula umngxuma ongaphakathi womzimba wevalve esezantsi ukusuka kumgodi ongaphakathi wevalve ephezulu, ukuze isiqu sevalve, idiski yevalve kunye nezinye iindawo ezingaphezulu kwe-diaphragm zikhululeke kwi-corrosion ephakathi, ukupakishwa kwesakhiwo sokutywina kushiywe, kwaye ukuvuza okuphakathi akuyi kwenzeka.
I-diaphragm eyenziwe ngerabha okanye iplastiki inomsebenzi wokutywina kakuhle. Njengoko i-diaphragm iyingxenye esengozini, kufuneka itshintshwe rhoqo ngokweempawu ze-medium. Ilinganiselwe ngezinto ze-diaphragm, i-valve ye-diaphragm ifanelekile kuxinzelelo oluphantsi kunye nobushushu obuphantsi.
Ivalve ye-diaphragm inokwahlulwa ibe ziindidi ezintandathu ngokwesakhiwo sayo: uhlobo lwendlu, uhlobo lwangoku oluthe ngqo, uhlobo lokunqunyulwa, ngokuthe ngqo ngohlobo, uhlobo lwesango kunye nohlobo lwe-angle elungileyo; Ifom yoqhagamshelo idla ngokuba ludibaniso lweflange; Ngokwemowudi yokuqhuba inokwahlulwa ibe ziindidi ezintathu zemanyuwali, zombane kunye nezomoya, phakathi kwazo i-pneumatic drive yahlulahlulwe ibe ngokuqhelekileyo ivulekileyo, ngokuqhelekileyo ivaliwe kwaye ibuyisela iindidi ezintathu.
Ivalve ye-rubber ene-diaphragm enerabha isetyenziswe ngokubanzi kwiikhemikhali, irhasi enyibilikisiweyo, unikezelo lwamanzi kunye ne-drainage, ukutya, amayeza, i-desulfurization yeplanti yamandla, isinyithi, iminerali, inkqubo yomphunga kwibhoyila.
Umahluko omkhulu phakathi kwevalve yerabha ene-pneumatic ene-diaphragm kunye nezinye iivalve kukuba ithatha isakhiwo ngaphandle kwebhokisi yokuhlohla; I-diaphragm yerabha inokwahlula ngokupheleleyo i-corrosion medium kumjelo wokuhamba kuzo zonke iindawo zokuqhuba, ngaloo ndlela isusa izinto ezingalunganga "zokuqhuba, ukukhutshwa, ukuvuza kunye nokuvuza" kweevalve eziqhelekileyo.
Ngenxa yendlela yokuhamba kakuhle kunye nokuchasana kokuhamba okuncinci kwevalve ye-diaphragm, isantya esikhulu sokuhamba sinokufumaneka.
Zininzi iindidi zeerabha onokukhetha kuzo kumphezulu ongaphakathi womzimba wevalvu. Ngoko ke, inokumelana ne-corrosion ephezulu.
Kuba itywina yirabha elastiki diaphragm. Ke ngoko, inokusebenza kakuhle kokutywina kunye namandla okuvala amancinci.
Ivalve yerabha ene-pneumatic ye-diaphragm yenziwe ngumzimba wevalvu, isigqubuthelo sevalvu, idiski yevalvu, isiqu sevalvu, idiaphragm kunye namanye amalungu okuqhuba.
Ukuvulwa nokuvalwa kwevalve kufezekiswa ngokujikeleza ivili lesandla. Isiphelo esiphezulu sesivalo sevalve siphawulwe ngombala wokubonisa onokubona indawo yokuvula okanye yokuvala yevalve ukubonisa ukuvuleka nokuvala i-valve. Xa ivili lesandla libekwe ngokwewotshi, ivili lesandla liya kuhla, kwaye idiski yevalve iya kuqhuba i-diaphragm phantsi ukuze inqumle indlela; Ngaphandle koko, i-valve iya kuvulwa kwaye umbala uya kutyhilwa.
Umgangatho wevalve ye-diaphragm: ngokuhambelana nemimiselo ye-GB12239 kunye neemfuno ze-BS5156.
