Chovala chowunikira ndikudalira kuthamanga kwa sing'anga yokha ndikutsegula ndi kutseka valavu ya valve, yomwe imagwiritsidwa ntchito pofuna kuteteza valavu yobwerera kumbuyo, yomwe imadziwikanso kuti check valve, valve ya njira imodzi, valve countercurrent, ndi valve back pressure.
Onani zochita za valve
Vavu yowunikira ndi mtundu wa valavu yodziwikiratu, ntchito yake yayikulu ndikuletsa kubweza kwa media, kupewa kupopera ndi kuyendetsa galimoto, komanso kutulutsa kwapakati.Ma valve owunikira angagwiritsidwenso ntchito kupereka mizere yomwe kupanikizika kungakwere kuti kupitirire kupanikizika kwa dongosolo mu dongosolo lothandizira.
Kugawika kwa ma cheki ma valve
Chongani mavavu akhoza kugawidwa malinga ndi kapangidwe kawo ndi kukhazikitsa:
1. Swing valve check valve
Swing check valve disc disc, yozungulira kuzungulira mpando wa valve woyendetsa 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 anthu. , koma osati pakuyenda kwamphamvu, kusindikiza kwake sikuli bwino ngati kukweza.Swing check valve imagawidwa kukhala imodzi, iwiri ndi theka mitundu itatu, mitundu itatuyi imagawidwa makamaka molingana ndi m'mimba mwake ya valve, cholinga chake ndi kuteteza sing'anga kuti asiye kuyenda kapena kubwereranso, kufooketsa mphamvu ya hydraulic.
2. Kwezani valavu yowunika
Chimbale chapakati pa mzere woyimirira wa valve body slide check valve, valavu yokweza cheke ingathe kuikidwa mu payipi yopingasa, muzitsulo zothamanga kwambiri zing'onozing'ono zowunikira valavu zingagwiritsidwe ntchito mu mpira.Kwezani mawonekedwe amtundu wa valavu ndi valavu yapadziko lonse lapansi (itha kugwiritsidwa ntchito ndi valavu yapadziko lonse lapansi), kotero kuti mphamvu yake yokana madzimadzi ndiyokulirapo.Mapangidwewo ndi ofanana ndi valavu yapadziko lonse lapansi, ndipo thupi la valve ndi disc ndizofanana ndi valavu yapadziko lonse lapansi.Kumtunda kwa chivundikiro cha valve ndi kumunsi kwa chivundikiro cha valve kumakonzedwa ndi manja otsogolera, pepala lotsogolera la valve likhoza kukhala lomasuka kukwera ndi kugwa mu pepala lowongolera nyali, pamene sing'anga kunsi kwa mtsinje, valavu ya disc sing'anga kukankhira lotseguka, pamene sing'anga kuyimitsa otaya, valavu chimbale ndi ofukula ankatera pa mpando, kuteteza sing'anga countercurrent kwenikweni.Kuwongoka-kupyolera mu kukweza cheke valavu yolowera pakati ndi njira yotulukira ndi njira yolowera pampando wa valve yolunjika;Valavu yokweza yoyimirira, njira yake yolowera ndi njira yotulutsira ndikuwongolera njira yapampando ndi yofanana, kukana kwamayendedwe ndikocheperako kuposa mowongoka.
3. Valumu yowunika ma disc
Vavu yoyang'ana momwe diski imazungulira mozungulira pini pampando.Maonekedwe a valavu ya disc ndi osavuta, amatha kukhazikitsidwa pamapaipi opingasa, osasindikiza bwino.
4. Valovu yoyang'ana chitoliro
Vavu pomwe chimbale chimatsetsereka pakatikati pa thupi.Valavu yoyang'ana chitoliro ndi valavu yatsopano, voliyumu yake yaying'ono, kulemera kwake, ukadaulo wabwino wokonza, ndi imodzi mwamagawo a chitukuko cha valavu.Koma coefficient yamadzimadzi yolimbana ndi madzi ndi yayikulu pang'ono kuposa mavavu a swing check.
5. Valavu yowunika kuthamanga
Vavu iyi imagwiritsidwa ntchito popangira madzi ophikira komanso valavu yodulira nthunzi, imakhala ndi valavu yokweza ndi globe valve kapena Angle valve integrated function.
Nortech ndi m'modzi mwa otsogola opanga ma valve ku China omwe ali ndi chiphaso cha ISO9001.
Zogulitsa zazikulu:Gulugufe Valve,Vavu ya Mpira,Chipata cha Chipata,Onani Vavu,Globe Vavlve,Y-Strainers,Electric Acurator,Pneumatic Acurators .
