hydraulic valve cartridge pressure reduction valve PBFB-LAN

Mfundo yogwira ntchito ya valve yothandizira ndi yosavuta kumvetsetsa, ndipo ndi valve yotetezeka yodziwika bwino yomwe imatha kuwongolera kuwonongeka komwe kumachitika chifukwa cha kuwonjezereka kwamadzimadzi.Valve yothandizira imadziwika ndi mapangidwe apadera, omwe sangathe kuwongolera kuthamanga kwa magazi, komanso kuteteza kubadwa kwa kupanikizika kwakukulu, kuti ateteze kayendetsedwe kabwino ka dongosolo ndi kuchepetsa kutayika.Valve yothandizira nthawi zambiri imagawidwa kukhala ma valve opumulira a nthunzi kapena amadzimadzi.Valavu yothandizira nthunzi nthawi zambiri imakhala ndi thupi la valve, spool ndi chivundikiro cha valve.Pamene kupanikizika mu dongosolo kumadutsa mtengo woikidwiratu, spool idzawuka, kutuluka kudzachepetsedwa, ndi kupitirira.
Nthunzi imatulutsidwa mu dongosolo, ndipo mphamvu yochitirapo imatsutsidwa kuti ikhazikitse kuthamanga kwa valve ya nthunzi pansi pa mtengo wokhazikitsidwa.Valavu yothandizira mpweya nthawi zambiri imakhala ndi thupi la valve, spool, valve, thrust screw, rabara pad, chivundikiro cha mpando ndi zina zotero.Kupanikizika kukakwera kupitirira mtengo wokhazikitsidwa, chivundikiro cha mpando chimakhala ndi chapamwamba, chotsika, pamwamba, mbale ya gridi ndi pisitoni kuti muwonjezere kukangana pakati pa chivundikiro cha mpando ndi thupi la valve, tsegulani ndodo ya piston ndi doko la pistoni, kotero kuti madzimadzi osefukira dongosolo.
Valavu yothandizira nthawi zambiri imagwiritsidwa ntchito pamakina operekera mpweya, monga ma jenereta a gasi, mapaipi ndi zida, zimagwira ntchito yoteteza, pamene kupanikizika kwa sing'anga kuli kwakukulu kuposa kapena kofanana ndi mtengo wokhazikitsidwa, valavu yothandizira imatsekedwa, pamene kupanikizika kwapakati kumakhala kwakukulu. sing'anga ndi yocheperapo kuposa mtengo wokhazikitsidwa, valavu yothandizira imatsegulidwa.Kuonjezera apo, valve yothandizira ingagwiritsidwe ntchito pazida zodziwika bwino zapakhomo, monga chillers, air conditioners ndi makina ochapira, zomwe zingathe kuteteza zipangizozi kuti zisawonongeke kwambiri, ndikugwiritsanso ntchito malire awo kuti zitsimikizire kuti zidazo zikugwira ntchito mokhazikika.
Zonsezi, valavu yothandizira imalepheretsa kupanikizika kwakukulu kuti isawononge dongosolo mwa kulamulira kupanikizika kwakukulu.Kuphatikiza apo, imatha kuchepetsa kuthamanga, kuteteza dongosolo kuti lisawonongeke, ndikuwonetsetsa kuti zidazo zikuyenda bwino.
