     Mfundo yogwira ntchito ya valve yothamanga

Valavu yoyenda ndi mtundu wa zida zowongolera kuti ziwongolere kutuluka kwamadzimadzi, mfundo yake yogwirira ntchito ndikuwongolera kukula kwamayendedwe posintha malo otaya mapaipi. Valve yoyenda imagwiritsidwa ntchito kwambiri pamakina otumizira ma hydraulic ndipo imagwira ntchito yofunika kwambiri. Zigawo zazikulu za valve yothamanga zimaphatikizapo thupi la valve, zinthu zoyendetsera (monga spool, valve disc, etc.) ndi actuator (monga electromagnet, hydraulic motor, etc.). Mitundu yosiyana ya ma valve othamanga imakhalanso yosiyana, koma mfundo zawo zogwirira ntchito ndizofanana.
Mfundo yogwira ntchito ya valve yothamanga ikhoza kugawidwa m'njira ziwiri: kusintha kwa malo a chinthu chowongolera ndi kuyenda kwa spool / disc.

Choyamba, pamene madzi akudutsa mu thupi la valve yothamanga, amakumana ndi chinthu chowongolera. Zinthu zowongolerazi zimakhala ndi malo ena mu thupi la valve, ndipo malo otaya madzi amatha kusinthidwa mwa kusintha malo awo. Mwa njira iyi, kutuluka kwa madzi kumatha kuyendetsedwa. Zomwe zimawongolera ndi spool ndi disc.

Kachiwiri, valavu yothamanga imakhalanso ndi spool kapena disc mechanism, yomwe kayendetsedwe kake kamasintha kayendedwe ka madzi kudzera mu thupi la valve. Mwachitsanzo, maginito amagetsi akayatsidwa, spool imasunthidwa mmwamba kapena pansi ndi mphamvu ya maginito. Izi zimasintha malo a chinthu chowongolera, chomwe chimawongolera kutuluka kwamadzimadzi. Mofananamo, pamene hydraulic motor imayendetsa diski ya valve kuti itembenuke, idzasinthanso malo othamanga amadzimadzi, motero imayendetsa kayendedwe kake.
