CBBC-LAN pilot regulator Large flow balancing valve

     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.

udindo wa valve yothandizira
1, kukhathamiritsa kosalekeza kumachulukirachulukira: mu kachulukidwe pampu yowongolera kachulukidwe, pampu yochulukira imapereka kuyenda kosalekeza. Pamene kupanikizika kwa dongosolo kumawonjezeka, kufunikira kothamanga kumachepa. izi
Pamene valavu yachitetezo imatsegulidwa, kutuluka kwakukulu kumabwezeretsedwa ku thanki kuti kuwonetsetse kuti kulowetsedwa kwa valve yotetezera, ndiko kuti, kuthamanga kwa pampu, kumakhala kosalekeza (doko la valve nthawi zambiri limakhala ndi mphamvu.
Mafunde amphamvu atseguke).
2, mphamvu yowongolera mphamvu: valavu yopumira imalumikizidwa motsatizana pamayendedwe obwerera mafuta, valavu yopumira imatulutsa kukakamizidwa kumbuyo, ndipo kukhazikika kwa magawo osuntha kumawonjezeka.
3, ntchito yotsitsa dongosolo: doko loyang'anira kutali la valve yothandizira limalumikizidwa ndi valavu ya solenoid yokhala ndi kusefukira kwakung'ono. Ma electromagnet akapatsidwa mphamvu, doko loyang'anira kutali la valavu yachitetezo ndi thanki yamafuta zimalumikizidwa
Kulumikizidwa, nthawi ino pampu ya hydraulic ikutsitsa. Valavu yotetezera imagwiritsidwa ntchito ngati valve yotetezera.
4, chitetezo cha chitetezo: pamene dongosolo likugwira ntchito bwino, valve imatsekedwa. Kusefukira kokha pamene katunduyo adutsa malire omwe atchulidwa (kupanikizika kwadongosolo kumaposa kukakamiza kokhazikitsidwa)
Valavu idzatsegulidwa, ndikutetezedwa mochulukira, kotero kuti kupanikizika kwa dongosolo sikuchulukiranso (kawirikawiri kupanikizika kwa valve yotetezera ndi 10% -20 dongosolo la kuthamanga kwapamwamba kuposa kuthamanga kwakukulu kogwira ntchito)
Mphamvu).
