Edrv dynamic balance electric control valve

The dynamic balance electric control valve ndi chinthu cham'badwo chatsopano chomwe ndi chosiyana ndi valavu yoyendetsera magetsi. Ndi mankhwala ophatikizika a mphamvu zamagetsi ndi kuwongolera magetsi.

M'mayendedwe osinthika oyenda ndi kusinthasintha kwakukulu kwa katundu wa dongosolo, pamene kupanikizika kwa dongosolo kumasintha, kusiyana kwa kuthamanga (P1-P3) kumapeto kwachiwiri kwa valavu yoyendetsera magetsi kumasinthanso.

(1) Pamene kulowetsedwa kwa P1 kumawonjezeka, (P1-P2) kumawonjezeka, spool ya valve yamagetsi imayenda pamwamba, kuchepetsa kutsegula pakati pa P1 ndi P2 ndi kuchepetsa kuthamanga kwa spool P2; pamene kulowetsedwa kwa P1 kumachepa, (P1-P2) kumachepetsa, spool ya valve yamagetsi imayenda pansi, kuwonjezera kutsegula pakati pa P1 ndi P2 ndikuwonjezera mphamvu ya spool P2. Choncho, ziribe kanthu momwe kupanikizika kwa dongosolo kumasinthira, kusiyana kwapakati pakati pa P2 ndi P3 sikunasinthe kupyolera mu kayendetsedwe ka spool yamagetsi yamagetsi. Choncho, valavu yamphamvu imakhala ndi mphamvu zotsutsana ndi kusokoneza komanso ntchito yowonjezereka yogwira ntchito;

(2) Pamene chowongolera chamagetsi chowongoka chimalandira chizindikiro chowongolera kuti chiwongolero cha valavu chisunthike mmwamba ndi pansi motsatira AB (kapena cholumikizira chamagetsi cha angular chimalandira chizindikiro chowongolera kuti shaft ya valve izungulira R), kutsegula pakati pa P2 ndi P3 imasinthanso. Ziribe kanthu momwe kusiyana kwa kuthamanga kwa dongosolo (P1-P3) kusinthira, kusiyana kwa kuthamanga (P2 - P3) pakati pa P2 ndi P3 sikunasinthe, kotero kuti mofanana ndi malo aliwonse otsegulira, madzi operekedwa amakhala osasinthasintha, komanso mayendedwe enieni oyenda valavu yoyendetsera magetsi imagwirizana ndi mawonekedwe ake oyenda bwino popanda kupatuka. Chifukwa chake, mtundu uwu wamagetsi owongolera magetsi uli ndi mawonekedwe abwinoko kuposa ma valve owongolera magetsi.
