Njenge-valve esetshenziswa kakhulu, i-valve yebhola nayo iwuhlobo oluningi lwe-valve.Izinhlobo ezehlukene zihlangabezana nohlelo lomsebenzisi ezikhathini ezihlukene ezimaphakathi, izindawo ezihlukene zezinga lokushisa kanye nezidingo zenqubo ehlukene enqubweni yangempela.Okulandelayo kwethula izici zamavalvu ebhola amaningana avamile njengama-valve ebhola antantayo, ama-valve ebhola angashintshi, ama-eccentric half ball valves, ama-valve ebhola amise okwe-V kanye nama-valve ane-fluorine yebhola.
Ngokuya ngesakhiwo nomsebenzi, ingahlukaniswa ibe:
1. Kunezinhlobo eziningana zama-valve ebhola.Ayini ama-valve ebhola antantayo: Amavalvu ebhola antantayo asetshenziswa njengezimpawu futhi ibhola liyantanta.Isebenzisa ukucindezela kwendawo ephakathi ukusunduza ibhola ukuze ihambe ibanga bese incindezela isihlalo sevalvu esinwebekayo ukuze sifinyelele umphumela wokuvala.Lolu hlobo lwe-valve yokuntanta lunokumelana nokuvuleka okukhulu futhi lufaneleka kuphela amapayipi nezinto zokusebenza ezinezinga le-DN “200 kanye nengcindezi ye-PN “100.Uma ububanzi bebhola bukhulu kakhulu, buzogoba umzimba we-valve futhi buhluleke ngaphansi kwengcindezi ye-medium;uma ukucindezela kuphezulu kakhulu, i-valve yebhola izocindezelwa futhi i-elastically futhi isihlalo se-valve esinwebekayo sizokhubazeka unomphela, okungase kulimaze uphawu futhi kuthinte i-valve yebhola.ukuphila.
2. I-valve yebhola engaguquki ilungiswa yiziqu ezimbili ezingenhla nezingezansi.Isihlalo se-valve sifakwe isiphethu seqabunga noma i-cylindrical spiral spring.Uma ifakwe, intwasahlobo yesihlalo se-valve iyacindezelwa ukuze ikhiqize amandla okuqinisa ngaphambili ukuze kuzuzwe uphawu lokuqala lwe-valve.Ukucindezela kuphusha i-valve ngesikhathi sokusetshenziswa.Isihlalo siya ebholeni ukuze kutholakale uphawu.Ngenxa yokuthi ibhola alinyakazi, libizwa ngokuthi i-valve yebhola engaguquki.Lolu hlobo lokulungisa luthembeke kakhulu kunama-valve amabhola antantayo ngenxa yokuthembeka kwawo ekutywineni.Ingasetshenziswa ebangeni elibanzi, hhayi kuphela kububanzi obuncane bokucindezela okuphansi, kodwa futhi nobukhulu bokucindezela okukhulu.Kodwa ukwakheka kwawo kuyinkimbinkimbi kakhulu
, Izindleko zentengo ziphezulu, lapho ukhetha, kufanele ukhethe ngokuvumelana nezidingo zangempela.
3. I-valve ye-hemispherical eccentric.Lolu hlobo lwe-valve yebhola luthatha isakhiwo esingenasici.Umgomo wesakhiwo uyafana nalowo wevalvevemvane enezingqimba eziningi ezintathu eccentric evalwe kanzima.Isihlalo sevalvu nebhola akugugi futhi kunomsebenzi wokuvala oqinile.Ibhola liyi-1/4 kuphela ye-valve yebhola evamile.Inobuso obugobile, isisindo esilula kanye nenani eliphansi uma kuqhathaniswa.Lokhu kunomthelela wokugunda futhi kungasetshenziswa epayipini eliphakathi nendawo eliqukethe imicu emide ngaphandle kokuminyana.
4. I-flange ye-valve yebhola yokushisa eshisayo iyincazelo eyodwa kuya kwezimbili ezinkulu kune-valve yebhola ye-flange evamile.Yamukela umzimba we-valve obalulekile kanye nomklamo webhola obekwe eceleni.Ijakhethi yensimbi ishiselwe phakathi kwama-flange akhulisiwe ngaphandle komzimba we-valve.Ibizwa nangokuthi i-valve yebhola enejakhethi.Izindawo zokusebenzelana ezinamajakhethi zifakwe ezinhlangothini zombili zomzimba we-valve, ezingashiswa ngesitimu noma enye igesi eshisiwe ngokweqile ukuze kuvinjelwe okuphakathi ukuthi kuqiniswe noma kucwebezeliswe ekamelweni lokushisa.Ama-valve amabhola okushisa asetshenziswa kakhulu kumapayipi kanye namadivayisi alula ukucwebezela futhi adinga ukufakwa kwe-thermal ku-petroleum, amakhemikhali, i-metallurgical, kanye nezinhlelo zemithi.
5. Ivalve yebhola emise okwe-V iyivalvu yebhola elawulayo.Imbobo yokugeleza kwebhola yehluke kakhulu kunembobo eqondile edlula embotsheni evamile yebhola.Ibhola linesakhiwo esimise okwe-V futhi ngokuvamile lithatha isakhiwo esinqunyiwe esineziqu ezimbili ezingenhla nezingaphansi.
6. Ivalvu yebhola ene-fluorine ivamise ukusetshenziswa kumazinga okushisa aphansi namapayipi ezinto ezidlayo ezimaphakathi.Lolu hlobo lwe-valve yebhola lufakwe amapulasitiki obunjiniyela amelana nokugqwala njenge-PFA noma i-FEP kuzo zonke izingxenye zesiteshi sokugeleza ezixhumene nendawo.Ingathatha indawo yensimbi engenasici ebizayo kanye ne-Hastelloy ngaphansi kwesimo sokungeqi izinga lokushisa lesevisi yenjoloba ye-fluorine epayipini lomfutho ophansi., i-Monel alloy, i-alloy No.

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