Valavu yoyendetsa yoyendetsa migodi Migodi yothandizira ma valve RSDC-LAN

Ma valve oyendetsa ndege amapezeka m'makonzedwe osiyanasiyana. Valavu yoyendetsa ndege yokhala ndi magawo atatu, yomwe imakhala ndi magawo awiri: valavu yoyendetsa ndi valavu yayikulu.

Vavu yoyendetsa taper, dzenje lotsekeka (bowo lokhazikika) pa spool yayikulu ndi kukakamiza kowongolera kasupe palimodzi kumapanga woyendetsa wa theka la mlatho wapang'onopang'ono wowongolera mayankho olakwika, omwe ali ndi udindo wopereka chiwongolero chachikulu cholamula pambuyo pa valavu yoyendetsa. kuwongolera kuthamanga kuchipinda chapamwamba cha spool yayikulu ya valve. Spool yayikulu ndikufanizira kwa loop yayikulu yolamulira. Nkhope yapamwamba imakhala ngati mphamvu yolamulira ya spool yaikulu, pamene nkhope yapansi yapansi imakhala ngati kupanikizika kwapakati pa chingwe chachikulu ndikuchita ngati mphamvu yoyankha. Mphamvu yotsatiridwayo imatha kuyendetsa spool, kusintha kukula kwa doko losefukira, ndipo pamapeto pake kukwaniritsa cholinga chowongolera ndikuwongolera kupanikizika kwa inlet P1.

YF mtundu wa magawo atatu oyendetsa ma valve oyendetsa ndege Chithunzi 1-(- valavu ya taper (valavu yoyendetsa); 2 - Mpando wa cone 3 - chivundikiro cha valve; 4 - Thupi la valve; 5 - dzenje lotayirira; 6 - valavu yayikulu; 7 - Main mpando 8 - kasupe wamkulu wa valve 9 - kuwongolera kuthamanga (vavu woyendetsa) masika 10 - kukonza zitsulo;

Ubwino wa valavu ya hydraulic system cartridge:

①Palibe kusintha kothamanga kwambiri:

Ichi ndi chomwe chimakonda kupwetekedwa mutu m'makina amphamvu kwambiri a hydraulic. Chifukwa valavu ya cartridge ndi mawonekedwe a valve conical conical, voliyumu yolamulira ndi yaying'ono posintha, ndipo palibe "chivundikiro chabwino" cha valve slide, kotero imatha kusinthidwa mofulumira. Pochita zinthu zina za zigawo za gawo loyendetsa ndege ndikusintha kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe kake

② Ndi kudalirika kwakukulu kosinthira:

valavu ya cone imakhala yovuta kuchititsa zoipa chifukwa cha dothi, kutaya pang'ono, kutentha pang'ono, ndipo spool ili ndi gawo lalitali lotsogolera, lomwe si losavuta kutulutsa chodabwitsa cha skew, kotero kuti ntchitoyi ndi yodalirika.

③ Chifukwa valavu ya cartridge logic yakhazikitsidwa kunyumba ndi kunja, kaya ndi muyezo wapadziko lonse lapansi wa ISO7368, Germany DIN 24342 ndi China (GB 2877 standard) anena za kukula kwapadziko lonse lapansi, komwe kungapangitse magawo a cartridge a opanga osiyanasiyana kusinthana, ndipo sichimaphatikizapo dongosolo lamkati la valve. Izi zimaperekanso ntchito yopangira ma hydraulic valve kuti asiye kukula kwakukulu kwa chitukuko.
