Isisekelo sokukhetha i-actuator kagesi ye-butterfly valve

A. I-torque yokusebenza

I-torque yokusebenza iyipharamitha ebaluleke kakhulu yokukhethaivalvu yebhabhathanei-actuator kagesi. I-torque yokukhipha ye-actuator kagesi kufanele ibe yi-torque ephezulu yokusebenza ephindwe ka-1.2 ~ 1.5ivalvu yebhabhathane.

B. Umfutho wokusebenza

Kunezakhiwo ezimbili eziyinhloko ze-ivalvu yebhabhathane i-actuator kagesi: enye ayinayo ipuleti lokusunduza, kanti i-torque ikhishwa ngqo; enye ifakwe ipuleti lokusunduza, kanti i-torque yokuphuma iguqulwa ibe yi-output thrust edlula ku-valve stem nut epuletini lokusunduza.

C. Inani lokujika komgodi wokukhipha

Inani lokujika komshini wokukhipha we-actuator kagesi we-valve lihlobene nobubanzi obujwayelekile be-valve, iphimbo lesiqu se-valve, kanye nenani lamakhanda anezintambo. Kufanele libalwe ngokuya nge-M=H/ZS (I-M iyinani eliphelele lokujika okufanele idivayisi kagesi ihlangane nalo, kanti i-H iyisilinganiso sokuvula kwe-Valve, i-S iyiphimbo lentambo ye-valve stem drive, i-Z iyinani lamakhanda esiqu sentambo).

D. Ububanzi besiqu

Kuma-valve e-stem akhuphukayo amaningi, uma ububanzi be-stem obukhulu obuvunyelwe yi-actuator kagesi bungakwazi ukudlula esiqwini se-valve efakiwe, abukwazi ukuhlanganiswa bube yi-valve kagesi. Ngakho-ke, ububanzi bangaphakathi bomshaft ophumayo ongenalutho wedivayisi kagesi kumele bube bukhulu kunobubanzi bangaphandle be-valve stem valve ye-stim ekhuphukayo. Kuma-valve ajika ingxenye kanye nama-valve e-dark-stem kuma-valve ajika amaningi, yize kungekho sidingo sokucabangela ukudlula kobubanzi be-valve stem, ububanzi be-valve stem kanye nosayizi we-keyway kufanele kucatshangelwe ngokugcwele lapho kukhethwa, ukuze i-valve isebenze ngokujwayelekile ngemva kokuhlanganiswa.

E. Isivinini sokuphuma

Uma isivinini sokuvula nokuvala kwevalvu yebhabhathane sishesha kakhulu, kulula ukukhiqiza isando samanzi. Ngakho-ke, isivinini sokuvula nokuvala esifanele kufanele sikhethwe ngokuya ngezimo ezahlukene zokusebenzisa.
