Ama-valve esango le-Taike angahlukaniswa abe:
1. I-valve yesango le-stem elikhuphukayo: I-valve stem nut ibekwe phezu kwekhava yevalvu noma kubakaki.Lapho uvula futhi uvala ipuleti lesango, i-valve stem nut iyazungeziswa ukuze kuzuzwe ukuphakamisa nokwehlisa isiqu se-valve.Lesi sakhiwo sinenzuzo ekugcobeni kwesiqu se-valve futhi sinezinga elibalulekile lokuvula nokuvala, ngakho-ke lisetshenziswa kabanzi.
2. I-valve yesango ye-stem engavuki: I-valve stem nut ixhumene ngqo nendawo engaphakathi komzimba wevalvu.Lapho uvula futhi uvala isango, kufinyelelwa ngokujikeleza induku ye-valve.Inzuzo yalesi sakhiwo ukuthi ukuphakama kwe-valve yesango kuhlala kungashintshiwe, ngakho-ke indawo yokufaka incane, futhi ifanele ama-valve esango anama-diameter amakhulu noma indawo yokufaka elinganiselwe.Lesi sakhiwo kufanele sifakwe inkomba yokuvula/yokuvala ukukhombisa izinga lokuvula/ukuvala.Ukungalungi kwalesi sakhiwo ukuthi izintambo zezintambo ze-valve azikwazi ukugcotshwa kuphela, kodwa futhi zibhekene ngqo nokuguguleka okuphakathi futhi zonakaliswe kalula.
Umehluko omkhulu phakathi kwama-valve esango le-stem akhuphukayo kanye nama-valve esango le-stem akhuphukayo yilawa:
1. Isikulufu esiphakamisayo se-valve yesango le-flange yesiqu esingavuki sizungeza kuphela ngaphandle kokuya phezulu naphansi.Okuvezwayo yinduku kuphela, futhi inadi layo ligxilile epuleti lesango.Ipuleti lesango liphakanyiswa ukuzungezisa kwesikulufu, ngaphandle kwe-gantry ebonakalayo;Isikulufu esiphakamisayo se-valve yesango le-flange yesiqu esikhuphukayo siyavezwa, futhi inathi linamathiselwe ngokuqinile kwisondo lesandla futhi lingashintshiwe (alizungezi noma alinyakazi nge-axially).I-gate plate iphakanyiswa ngokuzungezisa isikulufu.Isikulufu nepuleti lesango linokunyakaza okuhambisanayo kuphela kokuzungezisayo ngaphandle kokususwa kwe-axial okuhlobene, futhi ukubukeka kunikezwa ngobakaki omise okwesicabha.
2. “Amavalvu esiqu angaphumi awakwazi ukusibona isikulufu somthofu, kuyilapho ama-stem valve akhuphukayo angabona isikulufu somthofu.”.
3. Uma i-valve ye-stem engavuki ivulwa noma ivalwa, isiteringi nesiqu se-valve kuxhunywa ndawonye futhi akunyakazeki.Ivulwa noma ivalwe ngokuzungezisa isiqu se-valve endaweni engashintshi ukuze ishayele i-flap ye-valve iye phezulu naphansi.Ama-valve e-stem akhuphukayo aphakamisa noma ehlise i-valve flap ngokusebenzisa ukudluliswa okunentambo phakathi kwesiqu se-valve kanye nesondo lokuqondisa.Ukukubeka kalula, i-valve ye-stem ekhuphukayo iyidiski ye-valve eya phezulu naphansi kanye nesiqu se-valve, futhi isondo lokuqondisa lihlala lisendaweni engashintshi.
