Kapangidwe ka valavu
Zamkativalavu ya tayalandi gawo lofunika kwambiri la tayala lopanda kanthu, lomwe limagwiritsidwa ntchito kupopera, kuyeretsa ndi kusunga mpweya wina pamene tayala likugwiritsidwa ntchito ndikuwotchedwa. Kapangidwe ka valavu kayenera kuonetsetsa zofunikira izi: kudzaza bwino ndi kutulutsa mpweya bwino, kosavuta kuyang'ana kuthamanga kwa chubu chamkati, kulimba kwa mpweya wabwino, mpweya wosatuluka pansi pa kupanikizika komwe kwatchulidwa, kupanga kosavuta, kufotokozera kofanana, kusintha kosavuta; Pa kutentha kwakukulu kwa 100 ° C ndi kutentha kochepa kwa -40 ° C, rabala ilibe vuto, imatha kumangidwa ndikuphatikizidwa ndi chubu chamkati, ndipo ilibe kusweka, dzimbiri kapena kuchotsedwa kwa chophimba.
Njira yopumira
Chigawo cha valve chimayikidwa mu dzenje lamkati la kumapeto kwa chitoliro cha valve chamkati ndipo ndi valavu yolowera njira imodzi kuti chisindikizocho chikhale cholimba. Ikani chitoliro cha valve kuti chizungulire pang'onopang'ono, sichingakhale cholimba kwambiri (sichingatuluke), kuti mupewe kutsekeka kwa ulusi wa valve core, kulephera kwa masika, kutayika kwa gasket ya rabara; Nthawi yomweyo samalani pakamwa pa valve ndi ntchito za chitoliro cha valve core, zosavuta kuyeza barometer ndi kuvala chivundikiro cha valve. Musanapukutire, chitoliro cha valve (kuphatikizapo chitoliro cha valve) chiyenera kupukutidwa bwino kuti dothi lisalowe mu chubu chamkati. Mukapukutira, chitoliro cha valve sichiyenera kuchotsedwa kapena kupumulidwa, chifukwa nthawi zambiri chimachotsedwa ndikulowetsedwa, mphete yotsekera rabala imataya mphamvu yake pang'onopang'ono. Poyesa kuthamanga kwa mpweya, barometer iyenera kukhala pafupi ndi valavu yoyambira ya valavu, osakakamiza kwambiri, kuti isawononge makinawo, ikadzadzazidwa, iyenera kuyang'ana ngati valavu ikutuluka mpweya, ikapezeka kuti yatuluka, iyenera kukonzedwa nthawi yake kapena kusintha ziwalo zatsopano, osakoka mwamphamvu, kuti valavu isamasweke kapena nthawi ina yovuta kuchotsa. Muyenera kuvala chivundikiro chonse cha valavu, ndikulimbitsa molimba kuti mupewe fumbi, dothi mkamwa, zomwe zimapangitsa kuti pakhale kutsekeka ndi dzimbiri, kotero kuti kulephera kwa masika kungayambitse kutayikira pang'onopang'ono kwa mpweya.
Nthawi yosonkhanitsira
Tayala ndi mkombero zikasonkhanitsidwa, malo a valavu yolumikizira m'bowo la mkombero ayenera kusamalidwa ndipo palibe kupotoka komwe kumaloledwa, ndipo valavu yolumikizira iyenera kupewa dzenje loyang'anira mabuleki pochotsa pakati pa valavu, osathamanga kwambiri, kudina mwamphamvu, kuti ulusi usawonongeke.
Zambiri zazing'ono
Pogwiritsa ntchito matayala, n'zosavuta kunyalanyaza zinthu zazing'ono. Galimoto ikayimitsidwa m'mbali mwa msewu kapena pafupi ndi zinthu zina zokhazikika, mpweya wothira mpweya nthawi zambiri umakhudza chinthu monga msewu woyenda pansi. Pakadali pano, muzu wa mpweya wothira mpweya ukhoza kukhala m'mphepete mwa malire (wakuthwa kwambiri), zomwe zimapangitsa kuti mpweya utuluke (kutuluka kwamphamvu posachedwa, kuwala kumafunika kuyatsidwa kamodzi pa masiku angapo). Choncho yesetsani kuti musagwiritse ntchito mpweya wothira mpweya wautali kwambiri, kuti muchepetse izi. Pakadali pano, mtundu umodzi wa mpweya wothira mpweya wothira mpweya ndi wotchuka kwambiri, uli ndi chipangizo pamwamba, chomwe chingayambitse kuthamanga kwa mpweya komwe sikufunikira kumasula chivundikiro cha pakamwa, koma chikufunika kugwiritsa ntchito barometer mwachindunji. Ngakhale kuti mtundu uwu wa mpweya wothira mpweya ndi wosavuta, koma chivundikiro cha mpweya wothira mpweya ndi chachitali kwambiri, tikukulimbikitsani kuti musabweretse mavuto osafunikira kuti muchepetse mavuto.
