Njengevalvu esetshenziswa kakhulu,ivalvu yebholaFuthi uhlobo lwe-valve oluvame kakhulu. Izinhlobo ezahlukahlukene zihlangabezana nokusetshenziswa komsebenzisi ngezikhathi ezahlukene eziphakathi nendawo, izindawo zokushisa ezahlukene kanye nezidingo zenqubo ezahlukene enkambisweni yangempela. Okulandelayo kwethula izici zama-valve ebhola amaningana avamile njengama-valve ebhola antantayo, ama-valve ebhola aqinile, ama-valve ebhola eliyindilinga angavamile, ama-valve ebhola anomumo we-V kanye nama-valve ebhola ane-fluorine.
Ngokusho kwesakhiwo nomsebenzi, ingahlukaniswa ibe:
1. Kunezinhlobo eziningana zamavalvu ebhola. Yiziphiamavalvu ebhola antantayo: Amavalvu ebhola antantayo asetshenziswa njengezivalo futhi ibhola liyantanta. Lisebenzisa ingcindezi ye-medium ukusunduza ibhola ukuhambisa ibanga nokucindezela isihlalo se-valve elastic ukuze kufezwe umphumela wokuvala. Lolu hlobo lwevalvu entantayo lunokumelana okukhulu kokuvula futhi lufanelekela kuphela amapayipi nemishini ene-caliber ye-DN “200 kanye nengcindezi ye-PN “100. Uma ububanzi bebhola bukhulu kakhulu, buzogoba umzimba wevalvu bese buhluleka ngaphansi kwengcindezi ye-medium; uma ingcindezi iphezulu kakhulu, ivalvu yebhola izocindezelwa futhi inwebeke futhi isihlalo se-valve elastic sizokhubazeka unomphela, okungalimaza uphawu futhi kuthinte impilo yevalvu yebhola.
2. I-valve yebhola egxilile ihlelwa kabusha yiziqu eziphezulu nezingezansi. Isihlalo se-valve sifakwe isiphethu samaqabunga noma isiphethu esijikelezayo esiyindilinga. Uma sifakwe, isiphethu sesihlalo se-valve siyacindezelwa ukuze kukhiqizwe amandla okuqinisa ngaphambi kokufinyelela uphawu lokuqala lwe-valve, futhi ingcindezi iyacindezelwa ngesikhathi sokusetshenziswa. Isihlalo se-valve siya ebholeni ukuze kufinyelelwe uphawu. Ngenxa yokuthi ibhola alinyakazi, libizwa ngokuthi i-valve yebhola egxilile. Lolu hlobo lokuqinisa luthembeke kakhulu kune-valve yebhola entantayo ngenxa yokuthembeka kwalo kokuvala. Lingasetshenziswa ebangeni elibanzi, hhayi kuphela kumadayamitha amancane anomfutho ophansi, kodwa futhi nakumadayamitha amakhulu anomfutho ophezulu. Kodwa isakhiwo salo siyinkimbinkimbi kakhulu.
Intengo iphezulu, uma ukhetha, kufanele ukhethe ngokwezidingo zangempela.
3. Ivalvu ye-hemispherical eyingqayizivele. Lolu hlobo lwevalvu yebhola lusebenzisa isakhiwo esingavamile. Umgomo wesakhiwo ufana nowevalvu yebhabhathane enezingqimba ezintathu engavamile eqinile evaliwe. Isihlalo sevalvu nebhola akugugi futhi kunomsebenzi wokuvala oqinile. Ibhola liyi-1/4 kuphela yevalvu yebhola evamile. Linobuso obugobile, isisindo esincane kanye nentengo ephansi. Lokhu kunomphumela wokugunda futhi kungasetshenziswa epayipini eliphakathi eliqukethe imicu emide ngaphandle kokugoba.
4. I-flange ye-valve yebhola yokushisa eshisayo inezincazelo ezi-1 kuya kwezi-2 ezinkulu kune-valve yebhola ye-flange evamile. Isebenzisa umzimba we-valve ohlanganisiwe kanye nomklamo webhola ofakwe eceleni. Ijakethi yensimbi ihlanganiswa phakathi kwama-flange akhulisiwe ngaphandle komzimba we-valve. Ibizwa nangokuthi i-valve yebhola eboshwe ngejakethi. Ama-interface e-jakethi afakwe kuzo zombili izinhlangothi zomzimba we-valve, angahlanzwa ngomusi noma enye igesi eshisiwe kakhulu ukuvimbela ukuthi i-medium ingaqini noma i-crystallization ekushiseni kwegumbi. Ama-valve ebhola yokushisa eshisayo asetshenziswa kakhulu kumapayipi namadivayisi okulula ukuwakha futhi adinga ukufudumala e-petroleum, chemical, metallurgical, kanye ne-pharmaceutical systems.
5. I-valve yebhola enobunjwa buka-V iyi-valve yebhola elawulayo. Imbobo yokugeleza kwebhola ihluke kakhulu embobeni eqondile ye-valve yebhola evamile. Ibhola linesakhiwo esinobunjwa buka-V futhi ngokuvamile lisebenzisa isakhiwo esiqinile esineziqu ezimbili eziphezulu nezingezansi.
6. I-valve yebhola efakwe i-fluorine ivame ukusetshenziswa kumapayipi emishini ephakathi nendawo aphansi okushisa kanye naqinile. Lolu hlobo lwe-valve yebhola lufakwe amapulasitiki obunjiniyela amelana nokugqwala njenge-PFA noma i-FEP kuzo zonke izingxenye zomzila wokugeleza ezithintana nendawo. Ingathatha indawo yensimbi engagqwali ebizayo kanye ne-Hastelloy ngaphansi kwesimo sokungadluli izinga lokushisa lenkonzo yerabha ye-fluorine epayipini elinomfutho ophansi. , i-Monel alloy, i-alloy No. 20, ixazulula inkinga yokuthutha imidiya egqwala kakhulu emapayipini e-petrochemical kanye namakhemikhali.
