A. Itorque esebenzayo
I-torque yokusebenza iyipharamitha ebaluleke kakhulu yokukhethaivalve uvemvanei-actuator kagesi.I-torque ephumayo ye-actuator kagesi kufanele ibe izikhathi ezingu-1.2~1.5 kunetorque enkulu yokusebenzaivalve uvemvane.
B. I-Operating thrust
Kunezakhiwo ezimbili eziyinhloko zeivalve uvemvane i-actuator kagesi: eyodwa ayinayo i-thrust plate, futhi i-torque iphuma ngokuqondile;enye ifakwe i-thrust plate, futhi i-torque ephumayo iguqulwa ibe i-thrust ephumayo ngenadi le-valve stem ku-thrust plate.
C. Inani lokujika kwe-shaft yokuphumayo
Inombolo yokujika kwe-shaft ephumayo ye-valve actuator kagesi ihlobene nobubanzi be-valve, ukuphakama kwesiqu se-valve, kanye nenani lamakhanda anentambo.Kufanele ibalwe ngokwe-M=H/ZS (M uyingqikithi yenani lokujika okufanele idivayisi kagesi ihlangabezane nayo, futhi H ubude bokuvulwa kweValve, u-S uyingqikithi yentambo ye-valve stem drive, Z inombolo amakhanda entambo yesiqu).
D. Ububanzi besiqu
Ukuze uthole ama-valve e-stem aphendukayo amaningi, uma ubukhulu be-stem ububanzi obuvunyelwe i-actuator kagesi bungakwazi ukudlula esiqwini se-valve efakwe izinto, ngeke buhlanganiswe ku-valve kagesi.Ngakho-ke, ububanzi bangaphakathi bomgodi wokuphuma ongenalutho wedivayisi kagesi kufanele bube bukhulu kunobubanzi obungaphandle besiqu se-valve ye-valve yesiqu esikhuphukayo.Kuma-valve ayingxenye yokujika kanye nama-valve anesiqu esimnyama kuma-valve ajikajika amaningi, nakuba asikho isidingo sokucabangela ukudlula kobubanzi besiqu se-valve, ububanzi besiqu se-valve kanye nobukhulu bokhiye wokhiye kufanele futhi kucatshangelwe ngokugcwele. lapho ukhetha, ukuze i-valve isebenze ngokujwayelekile ngemva komhlangano.
E. Isivinini sokukhipha
Uma isivinini sokuvula nokuvala se-valve butterfly sishesha kakhulu, kulula ukukhiqiza isando samanzi.Ngakho-ke, isivinini esifanele sokuvula nokuvala kufanele sikhethwe ngokuvumelana nezimo ezihlukene zokusetshenziswa.
