Chowonjezera chofufutira cha 201-0950 solenoid valve msonkhano

Electromagnetic proportional valve ntchito mfundo ndi kuzindikira:

Kuwongolera kwa ma valve kumatha kugawidwa m'mitundu iwiri:
Imodzi ndikuwongolera kosinthira: mwina kutseguka kwathunthu kapena kutsekedwa kwathunthu, kuchuluka kwakuyenda kumakhala kwakukulu kapena kochepa, palibe gawo lapakati, monga ma elekitiroma wamba kudzera mu mavavu, ma elekitiromagineti otembenuza ma valve, ma electro-hydraulic reversing valves.
Zina ndikuwongolera mosalekeza: doko la valve likhoza kutsegulidwa malinga ndi kufunikira kwa digiri iliyonse yotsegulira, potero kulamulira kukula kwa kutuluka, ma valve oterowo ali ndi ulamuliro pamanja, monga ma throttle valves, komanso amawongoleredwa pakompyuta, monga molingana. ma valve, ma servo valves.
Chifukwa chake cholinga chogwiritsa ntchito valavu yofananira kapena valavu ya servo ndi: kukwaniritsa kuwongolera koyenda ndi kuwongolera zamagetsi (zowona, pambuyo pakusintha kwadongosolo kungathenso kuwongolera kuthamanga, etc.), popeza ndikuwongolera, payenera kukhala kutaya mphamvu, servo. valavu ndi ma valve ena ndi osiyana, kutaya mphamvu zake kumakhala kwakukulu, chifukwa kumafunika kuyenda kwina kuti kusungitse ntchito ya pre-siteji control mafuta dera.

Valavu yayikulu ya valavu ya servo nthawi zambiri imakhala yofanana ndi valavu yobwereranso ndi mawonekedwe a valavu, koma kutembenuka kwa valavu sikuyendetsedwa ndi maginito amagetsi, koma ndi mphamvu ya hydraulic ya valavu ya pre-stage valve, yomwe ndi zofanana kwambiri ndi valavu ya electro-hydraulic reversing valve, koma pre-siteji ya valve ya electro-hydraulic reversing valve ndi solenoid reversing valve, ndipo pre-siteji ya valve ya servo ndi valavu ya nozzle kapena valavu ya jet yomwe ili bwino. mawonekedwe amphamvu.
Izi zikutanthauza kuti, valve yaikulu ya valve ya servo imayang'aniridwa ndi kuthamanga kwa valve pre-stage valve, ndipo kuthamanga kwa valve pre-stage valve imachokera ku inlet p ya valve ya servo, ngati kuthamanga kwa p. doko silikwanira, valavu yoyambira-gawo silingathe kutulutsa mphamvu zokwanira kuti zilimbikitse kuchitapo kanthu kwa spool.
