Isisekelo sokukhetha i-Butterfly Valve Electric Actuator

A. Ukusebenza kwe-torque

I-torque esebenzayo iyipharamitha ebaluleke kakhulu yokukhethaI-valve yevemvaneI-Actuator kagesi. I-torque yokuphuma ye-actuator kagesi kufanele ibe ngu-1.2 ~ 1.5 izikhathi eziyi-1.5 I-torque ephezulu yeI-valve yevemvane.

B. Ukusebenza okusebenzayo

Kunezinhlaka ezimbili eziphambili zeI-valve yevemvane I-Electric Actuator: eyodwa ayifaki ipuleti elithe xaxa, futhi i-torque ikhipha ngokuqondile; Enye ifakwe ipuleti elithe xaxa, futhi i-torque yokuphuma iguqulwa ibe yindawo yokuphuma nge-valve stem nati ku-thrust plate.

C. Inani lokujika kokuphuma komshini

Inani lokujika komgwaqo ophumayo we-valve kagesi actuator lihlobene nobubanzi be-valve, iphimbo lesiqu se-valve, nenombolo yamakhanda anentambo. Kufanele kubalwe ngokusho kwe-M = H / ZS (M yinani eliphelele lokushintshana kwensiza kagesi okufanele lihlangane, futhi i-HAlve Fourpeight, s is the Thind Pitch of the Valve Stem drive,

D. Ububanzi be-STHEM

Ama-valves akhuphuke akhuphukayo akhuphukayo, uma ububanzi obukhulu obuvunyelwe yi-actuator kagesi abakwazi ukudlula esiqwini se-valve ehlomele, ngeke babuthene ku-valve kagesi. Ngakho-ke, ububanzi obungaphakathi komgodi we-hollow wokukhipha wedivayisi kagesi kumele ube mkhulu kunobubanzi obungaphandle kwesiqu se-valve ye-valve ye-stem ekhuphukayo. Ama-valves ajika ngengxenye nama-valves amnyama ashubile ngama-valves amaningi, yize asikho isidingo sokubheka ukudlula kwesiqu se-valve futhi usayizi we-keyve stem futhi usayizi we-keyve kufanele ubhekwe ngokugcwele lapho ukhetha, ukuze i-valve ingasebenza ngokujwayelekile ngemuva komhlangano.

E. Isivinini sokuphuma

Uma ijubane lokuvula nokuvala le-vetterfly valve lishesha kakhulu, kulula ukukhiqiza isando samanzi. Ngakho-ke, ijubane lokuvulwa elifanele nelivala kufanele likhethwe ngokuya ngemibandela ehlukene yokusetshenziswa.
