A. I-torque yokusebenza
I-torque yokusebenza yipharamitha eqakatheke khulu yokukhethaivalvu yevivaneumtjhini wokusebenza kagesi. I-torque yokuphuma kwe-actuator kagesi kufanele ibe yi-1.2~1.5 ye-torque ephezulu yokusebenza ye-ivalvu yevivane.
B. Ukugandeleleka kokusebenza
Kuneenhlaka ezimbili eziphambili zeivalvu yevivane umtjhini wegezi: enye ayifakwanga ipuleti lokugandelela, begodu i-torque iphuma ngqo; enye ifakwe ipuleti lokugandelela, begodu i-torque yokukhipha itjhugululwa ibe yi-thrust yokukhipha ngenati yesiqu sevalvu epuletini lokugandelela.
C. Inani lokujika kweshafu yokukhipha
Inani lokujika kwe-output shaft ye-valve electric actuator lihlotjaniswa nobubanzi be-valve, i-pitch yesiqu se-valve, kanye nenani leenhloko ezine-thread. Kufanele kubalwe ngokuya ngo-M=H/ZS (u-M inani elipheleleko lamajika isisetjenziswa segezi okufanele sihlangabezane nawo, begodu u-H ubude bokuvuleka kwevalvu, u-S yi-pitch yentambo ye-valve stem drive, u-Z linani leenhloko zentambo ye-stem).
D. Ububanzi besiqu
Emavalvu wesiqu aphakama ngokujika kanengi, nangabe ububanzi obukhulu besiqu obuvunyelwe mtjhini kagesi bungakghoni ukudlula esiquni sevalvu efakiweko, angeze yahlanganiswa ibe yivalvu kagesi. Ngalokho-ke, ububanzi bangaphakathi beshafti yokukhipha enomgodi wesisetjenziswa segezi kufanele bube bukhulu kunobubanzi bangaphandle besiqu sevalvu sevalvu yesiqu esikhuphukako. Emavalvu aphenduka ingcenye kanye namavalvu anesiqu esimnyama emavalvu ajika kanengi, nanyana kungekho sidingo sokucabangela ukudlula kobubanzi besiqu sevalvu, ububanzi besiqu sevalvu nobukhulu be-keyway nakho kufanele kuqalwe ngokuzeleko lokha nakukhethwa, ukwenzela bona ivalvu isebenze kuhle ngemva kokuhlanganiswa.
E. Ijubane lokukhipha
Nangabe ibelo lokuvula nokuvala kwevalvu ye-butterfly lirhaba khulu, kulula ukukhiqiza isando samanzi. Ngalokho-ke, ibelo elifaneleko lokuvula nokuvala kufanele likhethwe ngokuya ngeemeko ezihlukileko zokusebenzisa.
