Ntchito yavalavu ya mphira:
Valve ya rabara 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 pamphepete 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 imathandizanso kuti pakhale chitetezo?
Mphuno ya valve ndi tayala zimasiyanitsidwa:
Mphuno ya valve ndi njira imodzi yomwe imagwiritsidwa ntchito kudzaza mpweya mu tayala ndikusunga mpweya mu tayala, mphuno ya valve imasiyanitsidwa ndi tayala, ndipo mphuno ya valve imayikidwa pamphepete kuti igwire 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 valavu, ndiyo njira yokhayo yomwe mpweya umalowa mu tayala, umagwiranso ndi kuteteza pakati pa valve: nati yokhazikika, monga momwe dzinalo likusonyezera, imapanga 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 mupewe kutuluka kwa mpweya, ndipo kapu ya valve yomwe nthawi zambiri imatayika imatha kupewa thupi lakunja kuti lisasokoneze mphuno ya valve, ndipo nthawi yomweyo kukwaniritsa kusindikiza kwachiwiri kwa valavu ya valve Pamene pachimake chimapangitsa kuti gasi alowe 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, aluminiyamu alloy mitundu itatu ya valavu yakuthupi ndiyo yofala kwambiri. Mitundu itatu ya valavu ya mphira ya mphira ngati valavu yodziwika kwambiri, yotsika mtengo kotero kuti valavu ya rabara imasonkhanitsidwa kwambiri pamphepete mwa gudumu loyambirira.
Sinthani valavu ya rabara komanso tayala:
Chifukwa cha kukalamba kosalephereka kwa zida za mphira, thupi la valavu lidzasweka pang'onopang'ono, kusinthika, kutayika kwa 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 mofanana moyo utumiki tayala, choncho tikulimbikitsidwa kuti m'malo valavu mphira ndi tayala.
