Hlola ama-valve, obeye aziwe njengohlola ama-valvenoma ama-valve okuhlola, asetshenziselwa ukuvimbela ukubuyela emuva kwemidiya epayipini. I-valve yonyawo yokudonsa empompini yamanzi nayo iyingxenye yesigaba samavalvu okuhlola. Izingxenye ezivulayo nezivalayo zithembele ekugelezeni nasekuphoqeni okuphakathi ukuzivula noma ukuvala ngokwazo, ukuze kuvinjwe okuphakathi ukuthi kungagelezi emuva. Amavalvu okuhlola ayingxenye ye-automatic valve, asetshenziswa kakhulu kumapayipi lapho i-medium igeleza ibheke ohlangothini olulodwa, futhi ivumela okuphakathi ukuthi kugelezele ohlangothini olulodwa ukuze kuvinjelwe izingozi.
Ngokusho kwesakhiwo, i-valve yokuhlola ingahlukaniswa ngezinhlobo ezintathu: i-valve yokuhlola isheke,jika i-valve yokuhlolafuthii-valve yokuhlola uvemvane. Ama-valve okuhlola okuphakamisa angahlukaniswa abe ama-valve okuhlola aqondile kanye nama-valve okuhlola avundlile.
Kunezinhlobo ezintathu zeama-valve wokuhlola jika: ama-valve okuhlola i-single-lobe, ama-valve okuhlola ama-flap kabili nama-valve okuhlola ama-flap amaningi.
I-valve yokuhlola uvemvane iyi-valve yokuhlola i-straight-through, futhi ama-valve okuhlola angenhla angahlukaniswa abe izinhlobo ezintathu: i-valve yokuhlola uxhumano olucushiwe, i-valve yokuhlola uxhumano lwe-flange kanye ne-valve yokuhlola eshiselwe.
Kufanele kuqashelwe lezi zindaba ezilandelayo ekufakweni kwama-valve okuhlola:
1. Ungayenzi i-hlola i-valvethwala isisindo epayipini, futhi i-valve yokuhlola enkulu kufanele isekelwe ngokuzimela ukuze ingathinteki ukucindezela okukhiqizwa ipayipi.
2. Ngesikhathi sokufakwa, naka isiqondiso sokugeleza okuphakathi kufanele kuhambisane nesiqondiso somcibisholo ovotelwe umzimba we-valve.
3. Ivalvu yokuhlola i-flap ephakamisayo kufanele ifakwe epayipini elime mpo.
4. Ivalvu yokuhlola i-flap evundlile ephakamisayo kufanele ifakwe epayipini elivundlile. Iyini i-valve yokuhlola eqondile? Ama-valve okuhlola aqondile asetshenziswa kakhulu ezinhlelweni lapho kudingekile ukuvimbela ukugeleza emuva kwemidiya, njengokuphuma kwepompo, ukuphela kokugcwalisa amanzi ashisayo, kanye nokuphela kokumunca kwepompo ye-centrifugal. Umsebenzi wawo ukuvimbela imiphumela engase yenzeke ekuphumeni kwe-backflow ye-medium, isibonelo, uma ukuphuma kwepompo kungahlonywanga i-valve yokuhlola eqondile, amanzi abuya ngesivinini esiphezulu azobangela umthelela omkhulu ku-impeller yepompo lapho ipompo imisa ngokuzumayo; Uma i-valve yokuhlola emile (i-valve yonyawo) ingafakiwe ekugcineni kwepompo ye-centrifugal, iphampu idinga ukugcwaliswa njalo lapho iphampu ivuliwe.
Eminye imibuzo, ungaxhumana ne-TWS VALVE ekhiqiza ngokuyinhlokoivalve yevemvane ehlezi enganyakazi, i-valve yesango, i-valve yokuhlola, i-Y-strainer, njll.
