Izinga likazwelonke elisetshenziswa kakhului-valve yesangoi-valve yesango le-wedge.Isici sayo sesakhiwo ukuthi izindawo ezimbili zokuvala esangweni le-wedge kanye nezindawo zokuvala zemigqa emibili yokuzulazula emzimbeni wamavalvu zakha ipheya evalayo ukuze kuzuzwe umphumela wokuvala.Isakhiwo sawo silula, futhi uketshezi luncane, futhi luvame ukusetshenziselwa ukuthutha amabanga amade, amapayipi kanye nemishini yamanzi, uwoyela, igesi kanye neminye imidiya.Inhloso yokusebenzisa isango le-wedge ukukhulisa umthwalo wokufaka uphawu osizayo, ukuze i-valve yesango yemodi evalwe ngensimbi ikwazi ukuvala kokubili ukucindezela okuphakathi nendawo kanye nokucindezela okuphakathi okuphansi.Lapho uvala, zungezisa isiqu se-valve ngokwewashi ukuze wenze indawo yokuvala ye-valve yesango kanye nendawo yokuvala ye-valve ibe seduze ukuze ufinyelele uphawu.Kodwa-ke, ingcindezi ethile yophawu ekugcineni kwe-inlet ye-valve yesango yemodi evalwe ngensimbi ekhiqizwa isenzo sokushada ngokuvamile akwanele ukufeza uphawu lokuphela lokungena.Ngakho-ke, i-valve yesango yemodi evalwe ngensimbi iyisigxivizo esiphoqelelwe sohlangothi olulodwa.
Izikhathi ezisebenzayo ze-valve yesango lemodi:
Ububanzi bokusebenza kanye nezici zesakhiwo se-valve ye-wedge ejwayelekile kazwelonke, phakathi kwezinhlobo ezahlukene zama-valve, i-valve yesango iyona esetshenziswa kakhulu.Ngokuvamile ifaneleka kuphela ukuthi ivuleke ngokugcwele noma ivalwe ngokugcwele, futhi ayikwazi ukusetshenziselwa ukulungiswa kanye nokunyakazisa.
Amavalvu esango lemodi ngokuvamile asetshenziswa ezikhathini lapho kungekho mfuneko eqinile kubukhulu bangaphandle be-valve, futhi izimo zokusebenzisa zinokhahlo uma kuqhathaniswa.Njengendlela yokusebenza yokushisa okuphezulu nokucindezela okuphezulu, kuyadingeka ukuthi izingxenye zokuvala kufanele zivalwe isikhathi eside.
Ngokuvamile, izimo zokusebenzisa noma izidingo zidinga ukusebenza okuthembekile kokuvala, ukucindezela okuphezulu, ukunqanyulwa kwengcindezi ephezulu (umehluko omkhulu wengcindezi), ukunqanyulwa kwengcindezi ephansi (umehluko omncane wengcindezi), umsindo ophansi, i-cavitation kanye ne-vaporization, izinga lokushisa eliphezulu eliphakathi, izinga lokushisa eliphansi. (cryogenic), kunconywa ukusebenzisa i-valve yesango le-Wedge.Njengemboni yamandla kagesi, ukuhluzwa kwe-petroleum, imboni ye-petrochemical, uwoyela waphesheya kwezilwandle, ubunjiniyela bokuphakelwa kwamanzi kanye nobunjiniyela bokuhlanza indle ekwakhiweni kwamadolobha, imboni yamakhemikhali neminye imikhakha.
