Ing basi para mamili keng butterfly valve electric actuator

A. Operating torque

Ing operating torque iya ing pekamaulaga parameter para mamiliing balbula ning parulelectric actuator. Ing output torque ning electric actuator dapat 1.2~1.5 times ing maximum operating torque ninging balbula ning parul.

B. Operating thrust

Atin yang adwang manimunang istruktura ninging balbula ning parul electric actuator: ing metung ala yang thrust plate, at ing torque diretsu yang lulual; ing metung atin yang thrust plate, at ing output torque mibayu ya keng output thrust kapamilatan ning valve stem nut keng thrust plate.

C. Ing bilang da reng liko ning output shaft

Ing bilang da reng turn ning output shaft ning valve electric actuator makasuglung ya keng nominal diameter ning valve, ing pitch ning valve stem, ampo ing bilang da reng threaded heads. Dapat yang makalkula agpang keng M=H/ZS (M ing kabilugan a bilang da reng turns a dapat akit ning electric device, at H ing Valve opening height, S ing thread pitch ning valve stem drive, Z ing bilang da reng stem thread heads).

D. Diametru ning tangke

Para kareng multi-turn rising stem valves, nung ing maximum stem diameter a paintulutan ning electric actuator e ya malyaring dumalan keng stem ning equipped valve, e ya malyaring i-assemble keng electric valve. Uli na niti, ing kilub a diametru ning hollow output shaft ning electric device dapat mas maragul ya kesa keng kilwal a diametru ning valve stem ning rising stem valve. Para kareng part-turn valves ampo dark-stem valves kareng multi-turn valves, agyang ala nang kailangang ikonsidera ing pamaglakbe ning diametru ning valve stem, ing diametru ning valve stem ampo ing sukad ning keyway dapat lang lubus ikonsidera neng mamili, ban ing valve malyari yang magobra normal kaybat ning pamag-assemble.

E. Bilis ning pamaglual

nung ing bilis ning pamagbukas ampo pamagsara ning butterfly valve masyadu yang mabilis, madali yang gawang water hammer. Uli na niti, ing ustung bilis ning pamagbuklat at pamagsara dapat yang mamili agpang kareng miyayaliwang kundisyun ning pamangamit.
