Ukunqoba ukumelana kwentwasahlobo kwenza i-valve ivule noma ivale.Lapho ingcindezi emaphakathi ekugcineni kwe-inlet iphansi kunomkhawulo wokungena, i-valve yokuhlola eqondile: ngenxa yokucindezela okuphakathi ekugcineni kokungena kwepayipi.I-spring iphusha umgogodla we-valve esihlalweni se-valve ukuze uvale i-valve, ivimbele i-medium ukuthi ingabuyeli emuva, ngakho inomsebenzi ongabuyi.Ama-valve okuhlola aqondile asetshenziswa kakhulu kumakhemikhali, igesi ye-petroleum ewuketshezi, uketshezi nezinye izimboni.Ngokwesakhiwo se-valve yokuhlola, ingahlukaniswa ngezinhlobo ezintathu: i-valve yokuhlola i-lift, i-valve yokuhlola i-lift kanye ne-butterfly check valve.
I-valve esetshenziselwa ukuvimbela i-medium ukuthi ingagelezi emuva ibizwa nangokuthi i-valve yokuhlola, i-valve yendlela eyodwa, i-valve yokugeleza ehlehlayo, kanye ne-valve yokucindezela emuva.I-valve yokuhlola iwuhlobo lwe-valve othomathikhi, umsebenzi wayo oyinhloko ukuvimbela ukugeleza kwangemuva kwe-medium, ukuvimbela ipompo kanye ne-motor motor ukuthi ingahlehli, kanye nokukhishwa kwe-container medium.Amavalvu okuhlola angasetshenziswa futhi ukuhlinzeka ngamapayipi lapho ingcindezi ingase ikhuphukele ohlelweni olusizayo oludlula umfutho wesistimu.Ama-valve okuhlola angahlukaniswa abe ama-valve okuhlola ama-swing (ajikelezayo ngokuya phakathi nendawo ye-gravity) kanye nama-valve okuhlola okuphakamisa (ahamba nge-eksisi).Umsebenzi walolu hlobo lwe-valve ukuvumela kuphela okuphakathi ukuthi kugeleze ohlangothini olulodwa futhi kuvimbele ukugeleza kwesiqondiso.Ngokuvamile lolu hlobo lwe-valve lusebenza ngokuzenzakalelayo ngaphansi kwesenzo sokucindezela kwamanzi okugeleza ohlangothini olulodwa, i-valve flap iyavuleka;lapho uketshezi lugeleza ngakolunye uhlangothi, ukucindezela koketshezi kanye nokuziqondanisa kwe-valve flap kusebenza esihlalweni se-valve, ngaleyo ndlela kunqamule ukugeleza.Phakathi kwazo, i-valve yokuhlola intambo yangaphakathi kanye ne-valve yokuhlola eqondile ibhekisela ekuvuleni okuzenzakalelayo nokuvalwa kwe-valve clack kuye ngokugeleza kwe-medium ngokwayo.Ama-valve okuhlola axhunyiwe angawalolu hlobo lwe-valve, okuhlanganisa ama-valve okuhlola ama-swing nama-valve okuhlola okuphakamisa.I-valve yokuhlola i-swing ine-intermediary chain mechanism kanye ne-valve disc njengomnyango ohlezi ngokukhululekile ebusweni besihlalo se-valve ethambekele.Ukuze uqinisekise ukuthi i-valve clack ingafinyelela indawo efanele yesihlalo se-valve ngaso sonke isikhathi, i-valve clack yakhelwe ngendlela yamaketango ukuze i-valve clack ibe nesikhala esanele sokuphenduka futhi yenze i-valve clack ithinte ngempela isihlalo se-valve.I-valve clack ingenziwa ngensimbi, isikhumba, irabha, noma isembozo sokwenziwa singafakwa ensimbi, kuye ngezidingo zokusebenza.Lapho i-valve yokuhlola i-swing ivuliwe ngokugcwele, umfutho we-fluid cishe awuphazamiseki, ngakho-ke ukwehla kwengcindezi nge-valve kuncane kakhulu.I-valve disc ye-valve yokuhlola i-lift ihlezi endaweni yokuvala yesihlalo se-valve emzimbeni we-valve.Ngaphandle kokuthi i-disc ingaphakanyiswa futhi yehliswe ngokukhululekile, ingxenye esele yale valve ifana ne-valve yokuvala.Umfutho we-fluid uphakamisa i-disc endaweni yokuvala yesihlalo se-valve, futhi ukubuyela emuva kwe-medium kubangela ukuthi i-disc ibuyele esihlalweni futhi inqamule ukugeleza.Ngokwemibandela yokusetshenziswa, i-valve disc ingaba isakhiwo sensimbi yonke, noma ingaba ngesimo sephedi yerabha noma indandatho yerabha efakwe kuhlaka lwediski.Njenge-valve yokumisa, ukudlula koketshezi nge-valve yokuhlola i-lift nakho kuncane, ngakho-ke ukwehla kwengcindezi nge-valve yokuhlola i-lift kukhulu kunaleyo ye-valve yokuhlola i-swing, futhi ukugeleza kwe-valve yokuhlola i-lift kuvinjelwe kancane.

I-Nortech ingomunye wabakhiqizi abahamba phambili bamavalvu ezimbonini e-China abanesitifiketi sekhwalithi ye-ISO9001.
