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 ngokuzungeza 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 angakhuphuki yilawa:
1. Isikulufu sokuphakamisa 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 ngokuzungezisa isikulufu, ngaphandle kwe-gantry ebonakalayo; Isikulufu esiphakamisayo se-valve yesango le-flange yesiqu esikhuphukayo sivele obala, 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 okuzungezayo ngaphandle kokuguquguquka kwe-axial okuhlobene, futhi ukubukeka kunikezwa ngobakaki obunjengomnyango.
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 i-threaded transmission phakathi kwesiqu se-valve kanye nesondo lokuqondisa. Ukukubeka kalula, i-valve ye-stem ekhuphukayo iyidiski ye-valve ehamba phezulu naphansi kanye nesiqu se-valve, futhi isondo lokuqondisa lihlala lisendaweni engashintshi.
