Lapho ufaka i-valve, ukuze uvimbele insimbi, isihlabathi nezinye izinto zangaphandle ukuthi zingangeni ku-valve futhi zilimaze indawo yokuvala, isihlungi kanye ne-valve yokudonsa kufanele kufakwe;ukuze ugcine umoya ocindezelwe uhlanzekile, isihlukanisi samanzi samafutha noma isihlungi somoya kufanele sifakwe phambi kwe-valve.
Ngokucabangela ukuthi isimo sokusebenza se-valve singahlolwa ngesikhathi sokusebenza, kuyadingeka ukusetha izinsimbi kanyehlola ama-valve;ukuze ugcine izinga lokushisa lokusebenza, setha izinsiza zokulondoloza ukushisa ngaphandle kwe-valve.
Ukuze kufakwe emva kwe-valve, i-valve yokuphepha noma i-valve yokuhlola idinga ukufakwa;kucatshangelwa ukusebenza okuqhubekayo kwe-valve, elungele ingozi, uhlelo oluhambisanayo noma uhlelo lwe-bypass lusethiwe.
Hlola indawo yokuvikela i-valve
Ukuze uvimbele ukuvuza kwe-valve yokuhlola noma ukugeleza emuva kwe-medium ngemva kokuhluleka, okungabangela ukuwohloka kwekhwalithi yomkhiqizo futhi kubangele izingozi neminye imiphumela engathandeki, i-valve yokuvala eyodwa noma amabili afakwe ngaphambi nangemva kwe-valve yokuhlola.Uma ama-valve amabili okuvala enikezwa, i-valve yokuhlola ingahlakazwa kalula futhi ilungiswe.
Izinsiza zokuvikela amavalvu okuphepha
Ama-valve e-block ngokuvamile awafakwa ngaphambi nangemva kwendlela yokufaka, futhi angasetshenziswa kuphela ezimweni ezingazodwana.Uma amandla aphakathi nendawo equkethe izinhlayiya eziqinile futhi ethinta ukuthi i-valve yokuphepha ayikwazi ukuvalwa ngokuqinile ngemva kokusuka, i-valve yesango enophawu lokuhola kufanele ifakwe ngaphambi nangemva kwe-valve yokuphepha.I-valve yesango kufanele ibe sesimweni esivuleke ngokugcwele.DN20 hlola i-valve emkhathini.
Uma i-wax ekhipha umoya kanye nezinye izinto zemidiya kusesimweni esiqinile ekamelweni lokushisa, noma lapho izinga lokushisa loketshezi olukhanyayo nokunye imidiya lingaphansi kuka-0 degrees Celsius ngenxa yokuncipha kwegesi yokucindezela, i-valve yokuphepha idinga ukulandelela umusi.Kumavalvu okuphepha asetshenziswa emithonjeni ebolayo, kuye ngokuthi i-valve imelana nokugqwala, cabanga ukwengeza ifilimu engaqhume engagqwali endaweni yokungena kwamavalvu.
I-valve yokuphepha kwegesi ngokuvamile ifakwe i-bypass valve ngokobubanzi bayo ukuze ikwazi ukungena ngaphakathi.
Isikhungo sokuvikela i-valve yokunciphisa ingcindezi
Ngokuvamile kunezinhlobo ezintathu zezikhungo zokufaka ama-valve okunciphisa ingcindezi.Ama-gauge okucindezela afakwe ngaphambi nangemva kwe-valve yokunciphisa ingcindezi ukuze kube lula ukubhekwa kokucindezela ngaphambi nangemva kwe-valve.Kukhona futhi i-valve yokuphepha evaleleke ngokugcwele ngemuva kwe-valve ukuvimbela ukucindezela ngemva kokuba i-valve ingagxumi lapho ingcindezi ngemuva kwe-valve idlula ingcindezi evamile ngemva kokuhluleka kwe-valve yokunciphisa ingcindezi, kuhlanganise nesistimu engemuva kwe-valve.
Ipayipi lokukhipha amanzi lifakwe phambi kwe-valve yokuvala phambi kwe-valve, esetshenziselwa ikakhulukazi ukukhipha umfula okhipha amanzi, kanti abanye basebenzisa izicupho.Umsebenzi oyinhloko wepayipi le-bypass ukuvala ama-valve okuvala ngaphambi nangemva kwe-valve yokunciphisa ukucindezela lapho i-valve yokunciphisa ingcindezi ihluleka, ukuvula i-valve ye-bypass, ukulungisa ukugeleza ngesandla, futhi udlale indima yesikhashana yokujikeleza, ukuze kulungiswe i-valve yokunciphisa ingcindezi noma esikhundleni se-valve yokunciphisa ukucindezela.
Izinsiza zokuvikela izicupho
Kunezinhlobo ezimbili zepayipi le-bypass futhi alikho ipayipi lokudlula ohlangothini lwesicupho.Kukhona ukubuyiswa kwamanzi e-condensate kanye nenkokhelo yokungabuyiseli kwe-condensate, futhi umthamo wokudonsa amanzi wezicupho nezinye izidingo ezikhethekile zingafakwa ngokuhambisana.
Isicupho esine-valve yokudlula sisetshenziswa ngokuyinhloko ukukhipha inani elikhulu le-condensate lapho ipayipi liqala ukusebenza.Uma ulungisa isicupho, akufanelekile ukusebenzisa ipayipi ye-bypass ukukhipha i-condensate, njengoba lokhu kuzobangela ukuthi umusi ubaleke ohlelweni lwamanzi olubuyayo.
Ngaphansi kwezimo ezijwayelekile, ipayipi ye-bypass ayidingeki.Kuphela uma kunezidingo eziqinile ekushiseni okushisa, imishini yokushisa yokukhiqiza okuqhubekayo ifakwe ipayipi ye-bypass.
