Chogulitsa chabwino kwambiri cha H77X EPDM Seat Wafer Butterfly Check Valve ductile iron body EPDM seat SS416 Stem SS304 Spring From TWS
Kufotokozera:
Vavu yowunikira ya EH Series Dual plate waferIli ndi ma torsion spring awiri owonjezeredwa ku ma valve plate awiri, omwe amatseka ma valve mwachangu komanso modzidzimutsa, zomwe zingalepheretse kuti sing'anga ibwerere m'mbuyo. Valve yowunikira ikhoza kuyikidwa pa mapaipi olunjika komanso olunjika.
Khalidwe:
-Kakang'ono kukula, kopepuka kulemera, kakang'ono mu sturcture, kosavuta kukonza.
-Ma torsion spring awiri amawonjezedwa pa ma valve plates awiriwa, omwe amatseka ma plates mwachangu komanso modzidzimutsa.
-Nsalu yachangu imaletsa kuti chogwiriracho chisabwererenso.
-Kukhala ndi nkhope yofupikitsa komanso kulimba bwino.
-Kuyika kosavuta, kumatha kuyikidwa pa mapaipi opingasa komanso opingasa.
-Vavu iyi ndi yotsekedwa bwino, yopanda kutayikira pansi pa mayeso a kuthamanga kwa madzi.
-Yotetezeka komanso yodalirika ikugwira ntchito, Yosasokoneza kwambiri.
Mapulogalamu:
Kugwiritsa ntchito mafakitale ambiri.
