Ntchito yavalavu ya mphira:
Vavu ya mphira imagwiritsidwa ntchito kudzaza ndi kutulutsa mpweya mu tayala ndi kusunga mphamvu mu tayala.Valve ya valve ndi njira imodzi yokha, galimoto yogwiritsidwa ntchito mu tayala ilibe matayala azitsulo, mu kapangidwe ka valve ndi tayala imasiyanitsidwa wina ndi mzake, valve valve imayikidwa mumphepete kuti igwire ntchito yake.
Vavu mu tayala:
Monga gawo lokhalo la galimoto lomwe likukhudzana ndi pansi, tayala ndilofunika kwambiri pachitetezo cha galimotoyo.Kwa tayala, kuwonjezera pa korona, lamba, chingwe cha chingwe, mpweya wosanjikiza wa zigawo zingapo kuti amange mkati mwa mkati, kodi munayamba mwaganizapo kuti kamwa yaing'ono ya valve imagwiranso ntchito yofunikira pakuyendetsa chitetezo?
Mphuno ya valve ndi tayala zimasiyanitsidwa:
Mphuno ya valavu ndi njira imodzi yomwe imagwiritsidwa ntchito kudzaza mpweya mu tayala ndikusunga mpweya mu tayala, mphuno ya valve imasiyanitsidwa ndi tayala, ndipo phokoso la valve limayikidwa pamphepete kuti ligwire ntchito yake..
Mtundu uliwonse wa valavu uli ndi ntchito yake:
Ngakhale ntchito ya valavu nozzle ndi yaing'ono, koma dongosolo akhoza kugawidwa mu valavu thupi, gasket, gasket, yomanga.mtedza, valavu pachimake, valavu kapu zigawo izi, ndipo gawo lililonse lili ndi udindo wake.Kutenga valavu yachitsulo monga chitsanzo, mawonekedwe a valve, thupi la valve, ndiyo njira yokhayo yomwe mpweya umalowa mu tayala, umagwiranso ndi kuteteza chitsulo cha valve: mtedza wokhazikika, monga momwe dzinalo limatanthawuzira, umapanga phokoso la valve. ndichitsulo m'mphepeteotetezeka kwambiri;zida ziwiri zosiyana za gasket zimagwiritsidwa ntchito molumikizana ndi mtedza wokhazikika;Gasket ya rabara imagwiritsidwa ntchito kusindikiza mbali yamkati ya gudumu kuti muteteze kutulutsa mpweya, ndipo kapu ya valve yomwe nthawi zambiri imatayika imatha kulepheretsa thupi lakunja kusokoneza mphuno ya valve, ndipo nthawi yomweyo kukwaniritsa kusindikiza kwachiwiri kwa valavu. Ngakhale kuti valavu ya valve imatsimikizira jekeseni wosalala wa gasi mu tayala, imakhalanso ndi ntchito yoletsa mpweya kuti usatuluke.
Mitundu yosiyanasiyana ya ma valve:
Pambuyo poyambitsa valavu yazinthu zosiyanasiyana, tidzakudziwitsani zamitundu yosiyanasiyana yamagetsi kwa inu.Ndiko kulondola, monga zitsulo zosiyanasiyana zimagwiritsidwa ntchito pazinthu zonse zamagalimoto, valavu sikhalanso chinthu chimodzi cha mphira, zipangizo zachitsulo zakhala zikugwiritsidwa ntchito kwambiri mu valavu, ndipo pamsika wamakono, mphira, zitsulo, zitsulo zotayidwa mitundu itatu. za valavu zakuthupi ndizofala kwambiri.Mitundu itatu ya valavu ya mphira yamagetsi monga valavu yodziwika kwambiri, yotsika mtengo kotero kuti valavu ya rabara imasonkhanitsidwa kwambiri pamphepete mwa gudumu loyambirira.
Sinthani valavu ya rabara komanso tayala:
Chifukwa cha ukalamba wosalephereka wa zipangizo mphira, valavu thupi pang'onopang'ono kusweka, mapindikidwe, kutaya elasticity.Ndipo pamene galimoto ikuyendetsa galimoto, valavu ya rabara idzagwedezekanso mmbuyo ndi mtsogolo ndi centrifugal force deformation, yomwe idzapititse patsogolo kukalamba kwa mphira.Nthawi zambiri, moyo wa valavu mphira kwa zaka 3 -4, ndipo pafupifupi chimodzimodzi ndi moyo utumiki tayala, choncho tikulimbikitsidwa kuti m'malo valavu labala ndi tayala.
