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 valve, ndilo 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 mupewe kutulutsa mpweya, ndipo chipewa cha valve chomwe chimatayika nthawi zambiri chimatha kupewa kuti thupi lachilendo lisasokoneze 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 zipangizo zosiyanasiyana zitsulo ntchito mbali zonse za mbali galimoto, valavu salinso chimodzi mphira zakuthupi, zitsulo zipangizo akhala ankagwiritsa ntchito valavu, ndipo panopa msika mphira, zitsulo, zitsulo zotayidwa aloyi mitundu itatu. za valavu zakuthupi ndizofala 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.
