Butterfly valve electric actuator thlan dan tur a ni

A. Operating torque a ni

Operating torque hi thlan nan parameter pawimawh ber a nibutterfly valve a nielectric hmanga thawktu a ni. Electric actuator output torque chu operating torque sang ber aiin a let 1.2~1.5 a ni tur a nibutterfly valve a ni.

B. Operating thrust a ni

A structure lian ber pahnih a awm abutterfly valve a ni electric hmanga thawktu a ni: pakhat chu thrust plate hmanga thuam a ni lo va, torque pawh direct output a ni; pakhat zawk chu thrust plate hmanga thuam a ni a, chu output torque chu thrust plate chhunga valve stem nut kaltlangin output thrust-ah a chantir a ni.

C. Output shaft turn zat

Valve electric actuator output shaft turn zat hi valve nominal diameter, valve stem pitch leh threaded head awm zat nen a inzawm a ni. M=H/ZS (M chu electric device-in turn zawng zawng a tawn tur zat a ni a, H chu Valve hawnna san zawng a ni a, S chu valve stem drive thread pitch a ni a, Z chu stem thread lu awm zat a ni).

D. Stem diameter a ni

Multi-turn rising stem valve tan chuan electric actuator-in a phalsak stem diameter sang ber chu equipped valve stem a paltlang theih loh chuan electric valve-ah a inzawm khawm thei lo. Chuvangin electric device hollow output shaft chhung lam diameter chu rising stem valve valve stem pawn lam diameter aiin a lian zawk tur a ni. Multi-turn valve-a part-turn valve leh dark-stem valve tan chuan valve stem diameter kal dan ngaihtuah ngai lo mah se, thlan hunah valve stem diameter leh keyway lian leh te pawh ngaihtuah kim vek tur a ni a, chutiang chuan valve chu assembly zawhah a pangngaiin a thawk thei ang.

E. A chhuah chakna

Butterfly valve hawn leh khar chak lutuk a nih chuan water hammer siam a awlsam hle. Chuvangin, hman dan hrang hrang a zirin hawn leh khar speed dik tak thlan tur a ni.
