Khangela iivalvukufuneka zifakwe kwizixhobo, izixhobo kunye nemibhobho ukwenzela ukuthintela countercurrent medium.
Uxinzelelo oluncinci lokuvula i-valve yokutshekisha yi-0.002-0.004mpa.
Khangela iivalvuzifanelekile ngokubanzi ukucoca imidiya, kungekhona kwimidiya equkethe amasuntswana aqinileyo kunye ne-viscosity ephezulu.
Iivalve yonyawoiqhele ukufakwa kumbhobho othe nkqo wempompo yokungena, kwaye ophakathi uhamba ukusuka ezantsi ukuya phezulu.
Uhlobo lokuphakamisa lunomsebenzi ongcono wokutywina kunohlobo lwe-swing, kwaye inokumelana nolwelo olukhulu.Uhlobo oluthe tye kufuneka lufakwe kumbhobho othe tye, kwaye uhlobo oluthe tye kufuneka lufakwe kumbhobho othe nkqo.
Indawo yokufakela ivalve yokujonga i-swing ayikhawulelwanga.Inokufakwa kwiipayipi ezithe tye, ezithe nkqo okanye ezithambekileyo.Ukuba ifakwe kwimibhobho ethe nkqo, isikhokelo sokuhamba kwendlela ephakathi kufuneka sibe ukusuka ezantsi ukuya phezulu.
Iivalve zokujonga ujingiakufunekanga yenziwe ibe ziivalve zecaliber encinci, kwaye inokwenziwa kuxinzelelo oluphezulu lokusebenza.Uxinzelelo oluncinci lunokufikelela kwi-MPa engama-42, kwaye ububanzi obuqhelekileyo bunokuba bukhulu, ukuya kuthi ga kwi-2000 mm.Ingasetyenziswa kuyo nayiphi na indlela yokusebenza kunye naluphi na ubushushu obusebenzayo ngokwezinto zeqokobhe kunye netywina.Phakathi ngamanzi, umphunga, igesi, i-oyile, amayeza, njl njl.
I-valve yokukhangela i-swing ifanelekile kuxinzelelo oluphantsi kunye ne-caliber enkulu, kwaye ukufakwa kwayo kulinganiselwe.
Indawo yofakelo lwevalve yokujonga i-wafer ayikhawulelwanga.Inokufakwa kumbhobho othe tye okanye kumbhobho othe nkqo okanye othotyiweyo.
Iivalvu zokujonga ibholazilungele imibhobho yoxinzelelo oluphakathi noluphantsi kwaye inokwenziwa ibe yicaliber enkulu.
Izinto zeqokobhe levalve yokukhangela ibhola zingenziwa ngentsimbi engenasici, kwaye indawo engenanto yesitywina ingagqunywa kwiiplastiki zobunjineli be-PTFE.Ngoko ke, inokusetyenziswa kwakhona kwimibhobho yeendaba ezitshabalalisayo.Ubushushu bokusebenza buphakathi kwe-101 - 150 C, uxinzelelo oluncinci lungaphantsi kwe-4.0 MPa, kwaye uluhlu lokupasa okuqhelekileyo luphakathi kwe-DN200 - DN1200.
Khangela iivalvukufuneka ilinganiswe ngokufanelekileyo.Ababoneleli ngevalvu kufuneka babonelele ngedatha kwiisayizi ezikhethiweyo ukuze bafumane ubungakanani beevalvu xa zivuleke ngokupheleleyo ngesantya esinikiweyo sokuhamba.
Kuxinzelelo oluphezulu kunye oluphakathikhangela iivalvungaphantsi kwe-DN50mm,iivalvu zokujonga ukuphakamisa okuthe nkqokwaye ngephakamisa iivalve zokujongakufuneka kukhethwe.
Ngoxinzelelo oluphantsikhangela iivalvungaphantsi kwe-DN50mm,iivalve zokujonga i-waferkwayeiivalvu zokujonga ukuphakamisa okuthe nkqokufuneka kukhethwe.
Kuxinzelelo oluphezulu kunye oluphakathikhangela iivalvukunye ne-DN enkulu kune-50 mm nangaphantsi kwe-600 mm,swing check valveskufuneka kukhethwe.
Kuxinzelelo oluphakathi kunye noluphantsikhangela iivalvunge-DN enkulu kune-200 mm nangaphantsi kwe-1200 mm, ayinxibiiivalve zokujonga ibholakufuneka kukhethwe.
Ngoxinzelelo oluphantsikhangela iivalvukunye ne-DN enkulu kune-50 mm nangaphantsi kwe-2000 mm,iivalve zokujonga i-waferkufuneka kukhethwe.
Kwimibhobho efuna isando samanzi esingaphantsi okanye singabikho xa ivala, ivalve yokujonga ukujingi evala kancinci kufuneka ikhethwe.
