Edrv dynamic balance electric control valve

Tsanangudzo Pfupi

The dynamic balance electric control valve is a new generation product which is different from the classic electric control valve. Icho chigadzirwa chakabatanidzwa chekugadzirisa kuenzanisa uye kutonga kwemagetsi.

Mune inoshanduka inoyerera sisitimu ine kushanduka kukuru kweiyo system mutoro, kana iyo system kudzvanywa ichichinja, iyo yekumanikidza musiyano (P1-P3) pamagumo echipiri eiyo dynamic balance yemagetsi control valve inochinjawo.

(1) Apo inlet pressure P1 inowedzera, (P1-P2) inowedzera, spool yevhavha yemagetsi inofamba ichikwira kumusoro, kuderedza kuzarura pakati peP1 neP2 uye kuderedza spool pressure P2; apo inlet pressure P1 inoderera, (P1-P2) inoderera, spool yevhavha yemagetsi inofamba ichidzika, ichiwedzera kuvhura pakati peP1 neP2 uye kuwedzera spool pressure P2. Nokudaro, zvisinei kuti kudzvinyirirwa kwegadziriro kunoshanduka sei, kusiyana kwepakati pakati peP2 neP3 kunoramba kusingashanduki kuburikidza nekugadzirisa kwevhavha yemagetsi. Nokudaro, iyo valve ine simba ine simba rinopesana nekupindira uye simba rekuenzanisa basa;

(2) Kana iyo yakatwasuka yemagetsi actuator inogamuchira chiratidzo chekutonga kuita kuti vharafu shaft ifambe ichikwira uye ichidzika pamwe neAB (kana angular stroke electric actuator inogamuchira chiratidzo chekutonga kuita kuti shaft yevhavha itenderere pamwe neR), kuvhura pakati peP2 uye. P3 zvakare inoshanduka. Hazvina mhosva kuti mutsauko wekumanikidza system (P1-P3) unoshanduka sei, mutsauko wekumanikidza (P2 - P3) pakati peP2 neP3 unoramba usina kuchinjika, saka zvinoenderana nenzvimbo ipi neipi yekuvhura, kuyerera kwemvura kunounzwa kunogara kuripo, uye kuyerera chaiko kwemaitiro curve. iyo yemagetsi yekudzora vharafu inopindirana neyakanaka kuyerera kwayo hunhu curve pasina kutsauka. Naizvozvo, rudzi urwu rwemagetsi ekudzora vharafu ane zviri nani kudzora hunhu pane yechinyakare yemagetsi control valve.
