Hydraulic balance valve Excavator hydraulic cylinder spool PBHB-LCN

Ma valve opangidwa ndi hydraulic amagawidwa m'magulu anayi: kudzera mu valve, valve chitetezo, valve control ndi valavu yotsogolera. Choyamba, tiyeni timvetsetse valavu yodutsa. The through valve (yomwe imadziwikanso kuti general valve kapena shut-off valve) ndiyo valavu yodziwika kwambiri mu hydraulic system, yomwe imagwiritsidwa ntchito kuwongolera kutuluka kwamadzimadzi ndipo imayang'anira kutsegula ndi kutseka kwamadzimadzi. dongosolo la hydraulic. Mbali yaikulu ya valavu yodutsa ndi njira yosavuta, yosavuta kugwiritsa ntchito, yomwe imagwiritsidwa ntchito kwambiri m'mafakitale ndi ulimi wopangira ma hydraulic systems.

Chachiwiri, tiyeni tiwone ma valve otetezera. Valavu yotetezedwa (yomwe imadziwikanso kuti valavu yothandizira kapena valavu yodzaza) ndi gawo lofunikira mu hydraulic system kuteteza chitetezo cha zida ndi ogwira ntchito. Pamene kupanikizika kwa ma hydraulic system kumaposa mtengo wokhazikitsidwa, valavu yotetezera idzatsegulidwa mwamsanga, kotero kuti madzi ochulukirapo amatulutsidwa kudzera pa doko lakusefukira, potero kuteteza dongosolo ndi zipangizo kuti zisawonongeke. Valavu yachitetezo imadziwika ndi kuwongolera kukakamiza komanso kudalirika kwakukulu, komwe kumagwira ntchito yofunika kwambiri pama hydraulic system.

Mtundu wachitatu wa hydraulic valve ndi valve control. Valve yowongolera imagwiritsidwa ntchito kuwongolera kuthamanga, kuyenda ndi kuwongolera kwamadzi mu hydraulic system, kuti akwaniritse kuwongolera kolondola kwadongosolo. Makhalidwe akuluakulu a valve yolamulira ndizovuta komanso ntchito zosiyanasiyana, zomwe zimagwiritsidwa ntchito kwambiri pamakampani opanga makina opanga makina. Pali mitundu yambiri ya ma valve olamulira, ma valve omwe amawathandiza, ma valve otsogolera, ma valve oyendetsa ndi zina zotero. Valavu iliyonse yowongolera ili ndi mawonekedwe ake ndi ntchito zake, ndipo imatha kusankhidwa malinga ndi zosowa zenizeni.
