Hlola i-valve, eyaziwa nangokuthi i-valve yokuhlola, i-valve yokugeleza eyodwa, i-valve yokuhlola noma i-valve yokuhlola, indima yayo ukuqinisekisa ukuthi okuphakathi kwepayipi okuqondisa ukugeleza ngaphandle kokuphindela emuva. Ukuvulwa nokuvalwa kwe-valve yokuhlola kuncike ekuphumeni kwamandla okuphakathi ukuvula nokuvala. I-valve yokuhlola ingeyemikhiqizo ye-valve ezenzakalelayo, i-valve yokuhlola ivumela kuphela okuphakathi ukuthi kugele ohlangothini olulodwa lwepayipi elizosetshenziswa, ukuvimbela ukwenzeka kokuphindela emuva okuphakathi. Inezicelo ezahlukahlukene, futhi ingasetshenziswa kuma-calibers amakhulu namancane, imidiya ehlukahlukene nesiteshi samandla esistimu yamandla aphezulu.
Umgomo we-valve yokuhlola: ukuvula i-valve evulekile kusho ukuthembela ekugelezeni okuphakathi nendawo ukuvula i-disc, isizathu esifanayo ukugeleza emuva okuphakathi ukukhuthaza i-disc futhi kuvaliwe, i-valve yokuhlola yaziwa nangokuthi i-valve yokuhlola, i-valve yendlela eyodwa , i-reverse flow valve ne-valve yangemuva yokucindezela. Umsebenzi oyinhloko we-valve ukuvikela ukugeleza okuphindayo kwaphakathi, ukuvimbela ukuguqulwa kwepompo kanye nemoto yokushayela nokukhishwa kwendawo yangaphakathi yesiqukathi. Ibuye isetshenziselwe ukuvikela ukuphepha ezinhlelweni ezisizayo lapho ingcindezi ingakhuphuka ngaphezu kwengcindezi yohlelo.
Hlola ukuhlukaniswa kwe-valve: isheke valve isetshenziswa kakhulu ukuvimbela ukusetshenziswa kokugeleza kwemidiya emuva kwepayipi. I-valve engezansi ne-duck bill valve nakho kungokwesistimu ye-valve yokuhlola.
Hlola i-valve ingahlukaniswa ngohlobo lokuphakamisa, uhlobo lwe-swing, uhlobo lwediski lwesithathu:
Uhlobo lokuphakamisa luhlukaniswe ngezinhlobo ezi-2 ezimile futhi eziqondile, isakhiwo sokuphakamisa sihamba eceleni kwe-eksisi.
Izibonelo:
(1) Uhlobo lokuphakamisa isheke lokuvala buthule lisetshenziswa ekuhlinzekweni kwamanzi kanye nezidingo zobunjiniyela bamanzi wepayipi; Ngasikhathi sinye, ingafakwa lapho kuthengwa khona ipompo, futhi inethiwekhi yepayipi enengcindezi ephezulu kakhulu (i-PN2.5Mpa) ingumkhiqizo obalulekile we-valve yokuhlola umthelela ongangeni manzi.
(2) Ukuphakamisa uhlobo lwesilencer isheke valve kulungele ukuphakelwa kwamanzi okwakha okuphezulu kanye nohlelo lokuhambisa amanzi kanye nendawo yokumpompa, engazifanele izikhathi zepayipi lendle.
(3) I-valve yokuhlola evundlile ilungele ukuntywila, ipayipi lendle, ikakhulukazi uhlelo lwendle nodaka.
Uhlobo lwe-swing luhlukaniswe ngohlobo lwe-valve eyodwa, uhlobo lwama-valve amabili nohlobo lwama-valve amaningi. Isakhiwo sohlobo lwe-swing sikhethwe ngokuya ngesikhungo sokuzungezisa amandla adonsela phansi.
Izibonelo:
(1) Kukhethwa uhlobo oluvulekile lwenjoloba yokuhlola iraba elisetshenziswa ohlelweni lwenethiwekhi yamapayipi amanzi, engalifanele ipayipi lendle elinenzika eningi.
(2) I-valve yohlobo olulodwa lwe-Swing valve eyodwa inebanga lokusetshenziswa kakhulu, ingafakwa ekunikezelweni kwamanzi nangamapayipi, uphethiloli, amakhemikhali, insimbi, izimboni namanye amapayipi, izikhathi ezifanele kakhulu zemikhawulo yesikhala.
Isakhiwo sesitsha siqonde ngqo.
Isibonelo:
(1) I-disc disc disc valve valve isetshenziswa kakhulu kupayipi lokuphakela amanzi eliphezulu lokwakha, eliqukethe imithombo yezindaba ekhukhumezayo kanye nendle ekusetshenzisweni kwenethiwekhi yamapayipi amanzi.
(2) I-valve yohlobo olulodwa lwe-Swing valve eyodwa inebanga lokusetshenziswa kakhulu, ingafakwa ekunikezelweni kwamanzi nangamapayipi, uphethiloli, amakhemikhali, insimbi, izimboni namanye amapayipi, izikhathi ezifanele kakhulu zemikhawulo yesikhala.
I-valve yokuhlola evundlile ilungele ukuntywila, ipayipi lendle, ikakhulukazi uhlelo lwendle nodaka.
