Isiseko sokukhetha i-butterfly vetrourator yombane

A. Itroce

I-torque esebenzayo yeyona parameter ibaluleke kakhulu ekukhetheniivalve yebhabhathaneI-AcTurator yombane. I-Truge yeXesha leMbuso kufuneka ibe yi-1.2 ~ amaxesha ayi-1,5 elona liphezulu lokusebenza kweivalve yebhabhathane.

B. Usebenze

Zimbini iindlela eziphambili zeivalve yebhabhathane I-Accourtor yombane: Inye ayifakwanga ngeplate ephosakeleyo, kwaye itota ikhuphe ngqo; Elinye lixhotywe ngeplate ecekeceke, kwaye i-throce iguqulwe ibe yimveliso ye-valve ye-valve kwiplate.

C. Inani leenguqu ze-shaft yemveliso

Inani leenguqu ze-shaft yemveliso ye-valve ihambelana nobukhulu bevalute, i-valve ye-valve, kunye nenani leentloko ezinezintambo. Kufanele ukuba ibalwe ngokwe-M = H / ZS (M linani lilonke lokujika kwesixhobo sombane kufuneka sihlangane, kwaye i-valve yovelwano ukuqhuba, i-s yinxalenye yeentloko zentambo ze-valti).

D. I-stem diameter

I-valves enyukayo enyukayo, ukuba i-stem ye-stem ye-stem evunyelwe ngumncedisi wombane akanakudlula kwisiqu sevalve enamanzi, ayinakuhlanganiswa kwivalve yombane. Ke ngoko, ububanzi bayo bangaphakathi beshaphu yesixhobo sombane kufuneka ibe nkulu kune-vameter ye-valve ye-valve ye-stem valve. Ngeevalves zenxalenye ye-valve kunye neevali ezimnyama kwiivalves ezininzi, nangona kungekho mfuneko yokuqwalaselwa kwendawo ye-valve, ubukhulu be-valu stem kunye nokukhetha, ukuze ivali inokusebenza ngokwesiqhelo emva kwendibano.

E. Isantya semveliso

Ukuba isantya sokuvula kunye nokuvala kwivalve yebhabhathane ngokukhawuleza kakhulu, kulula ukuvelisa isando. Ke ngoko, isantya esifanelekileyo sokuvula kunye nokuvala kufuneka sikhethwe ngokweemeko ezahlukeneyo zokusebenzisa.
