Iivalve zesango le-Taike zinokwahlulwa zibe:
1. Ivalve yesango lokunyuka: I-valve stem nut ibekwe kwisigqubuthelo sevalve okanye isibiyeli.Xa uvula kwaye uvala ipleyiti yesango, i-valve stem nut ijikeleziswa ukufezekisa ukuphakamisa kunye nokwehliswa kwe-valve stem.Esi sakhiwo sinenzuzo kwi-lubrication ye-valve stem kwaye inezinga elibalulekileyo lokuvula nokuvala, ngoko lisetyenziswa ngokubanzi.
2. Ivalve yesango ye-stem enganyukiyo: I-valve stem nut idibana ngokuthe ngqo nophakathi ngaphakathi kumzimba wevalvu.Xa uvula kwaye uvala isango, kufumaneka ngokujikeleza intonga yevalve.Inzuzo yesi sakhiwo kukuba ukuphakama kwe-valve yesango kuhlala kungatshintshi, ngoko ke indawo yokufakela incinci, kwaye ifanelekile kwiivalve zesango ezinobubanzi obukhulu okanye indawo yokufakela encinci.Esi sakhiwo kufuneka sixhotyiswe ngesalathisi sokuvula / sokuvala ukubonisa iqondo lokuvula / lokuvala.Ukungalungi kwesi sakhiwo kukuba iintambo ze-valve azikwazi ukuthanjiswa kuphela, kodwa zixhomekeke ngokuthe ngqo kukhukuliseko oluphakathi kwaye zonakaliswe lula.
Owona mahluko uphambili phakathi kweevalvu zesango lesiqu esinyukayo kunye neevalvu zesango lesikhondo ezinganyukiyo zezi:
1. I-screw yokunyusa yevalve yesango ye-flange enganyukiyo ijikeleza kuphela ngaphandle kokunyuka nokuhla.Into evezwayo yintonga kuphela, kwaye i-nut yayo igxininiswe kwi-plate yesango.Iplate yesango iphakanyiswe ngokujikeleza kwe-screw, ngaphandle kwe-gantry ebonakalayo;I-screw yokunyusa i-valve yesango le-flange ye-stem ephakamayo ibonakalisiwe, kwaye i-nut inamathele ngokuqinileyo kwi-handwheel kwaye igxininisekile (ingajikelezi okanye i-axially ihamba).Ipleyiti yesango iphakanyiswa ngokujikelezisa isikrufu.Isikrufu kunye nepleyiti yesango zinentshukumo ejikelezayo kuphela ngaphandle kokufuduswa kwe-axial, kwaye inkangeleko ibonelelwa ngesibiyeli esimilise umnyango.
2. “Iivalvu zesikhondo ezinganyukiyo azikwazi ukusibona isikrufu sokukhokela, ngelixa iivalve zesikhondo ezinyukayo zinokubona isikrufu sokukhokela.”.
3. Xa ivalve yesikhondo esinganyukiyo ivulwa okanye ivalwa, ivili lokuqhuba kunye nesiqu sevalve ziqhagamshelwe kunye kwaye azishukumi.Ivulwa okanye ivalwe ngokujikelezisa isiqu sevalve kwindawo esisigxina ukuqhuba i-flap yevalve phezulu nasezantsi.Iivalvu zesikhondo ezinyukayo zinyusa okanye zehlise i-flap yevalve ngokusebenzisa umsonto wosasazo phakathi kwesikhondo sevalve kunye nevili lokuqhuba.Ukuyibeka ngokulula, i-valve ye-stem yokunyuka yi-disc yevalve ehamba phezulu nangaphantsi kunye ne-valve stem, kwaye ivili lokuqhuba lihlala likwindawo esisigxina.
