Ngati valve iyenera kusankhidwa chifukwa cha kutentha kwakukulu, zinthuzo ziyenera kusankhidwa molingana.Zida za ma valve zidzatha kupirira kutentha kwakukulu ndikukhalabe okhazikika pansi pa dongosolo lomwelo.Mavavu pa kutentha kwakukulu ayenera kukhala amphamvu kumanga.Zidazi zimatha kukhala zitsulo zosapanga dzimbiri komanso zitsulo zosapanga dzimbiri ziwiri.Zida zotsika kwambiri zomwe zingakhudze kutentha kwa kutentha siziyenera kugwiritsidwa ntchito, apo ayi ma deformation kapena ma valve a zinthu zokwawa ayenera kupewa.

Kutentha kwapamwamba

Mavavu agulugufe a Throttle akhoza kukhala okhazikika pansi pa kutentha kwakukulu.Kapangidwe ndithupi la valavuiyenera kuganiziridwa pamodzi ndi radiator kuti ikhale yokonzedwa ndi zipangizo zoyatsira kutentha.Ngati valavu imaganiziridwa, zinthu za valve sizikhazikika.Ngati kutentha kumadutsa malire omwe valavu imatha kupirira, sichingakhale choyenera pa valve yanu.

Muyenera kuganizira mavavu okhala ndi mapaipi a ceramic kapena mavavu okhala ndi jekete zoziziritsira kuti muchepetse kutentha.Ma jekete ozizira awa amagwira ntchito ndi kufalikira kwa madzi ozizira.Choncho, zinthumu valavuadzakhala bwino popanda chapamwamba malire malire.

Kutentha kwapansi

Ngati kutentha kuli kotsika kwambiri, monga -29℃, valavu yokhala ndi coefficient yotsika kutentha iyenera kusankhidwa.Pakutentha kotsika kwambiri kwa - 29 mpaka - 196 madigiri Celsius, chipolopolo ndi zida zochepetsera zimakhala ndi mphamvu zokwanira kuti zisunge kutentha ndikuwongolera zotsatira za kutentha kotsika kwambiri.

Munyengo yotsika iyi, muyenera kusankha valavu yokhala ndi zinthu zodzaza ndi gawo la tanki yamadzi kuti muzitha kuyendetsa kutentha.Kusankhidwa kwa ma valve awa kumathandizira kuti kutentha kusungidwe pamwamba pa 0℃.

Kusamala pa kutentha kosiyana

Pali njira imodzi yokha yodzitetezera ku ma valve.Vavu ikatsekedwa, madzi ena m'chipinda cha valve adzakhala otsekedwa.M'kupita kwa nthawi, madzi ena amakhalabe m'chipinda cha valve.Choncho, kutentha kumatengedwa pang'onopang'ono ndi mlengalenga ndikufikiranso kutentha komweko, kapena kutuluka m'chipinda cha valve.

Izi zikachitika, voliyumu idzawonjezeka pafupifupi nthawi 600, zomwe zidzabweretsa mphamvu yodabwitsa ku thupi la valve.Kupanikizika kwakukulu kumeneku kapena kupanikizika kwa valve thupi kumatchedwa abnormal pressure value.Mkhalidwewu ndi wosalamulirika, kotero ukhoza kuyambitsa mavuto aakulu a valve ndipo ukhoza kukhala gwero la ngozi.

Kuti mupewe zochitika zosafunikira izi za valve pansi pa kutentha kwambiri, muyenera kusankha valavu yokhala ndi orifice yokhazikika bwino.Valavu yamtunduwu imagwiritsidwa ntchito nthawi zambiri, ndipo njirayi imagwiritsidwa ntchito kwambiri pamundawu.

kufunikira kwa magwiridwe antchito

Choyamba, muyenera kufotokozera zofunikira zonse za kutentha ndi kupanikizika.Muyenera kutchula kutentha ndi kuthamanga kwa valve yomwe mukufuna kugwiritsa ntchito.Zidzakuthandizani kusankha valavu yakuthupi yoyenera kutentha kosiyana.Tiyerekeze kuti mukufuna kugwiritsa ntchito valavuyi pa kutentha kwakukulu.Pankhaniyi, tikulimbikitsidwa kugwiritsa ntchito valavu yachitsulo chifukwa imatha kupirira kutentha kwambiri kuposa zinthu zina.Ngati mpweya kapena kuthamanga kwamadzi mu valavu ndipamwamba kwambiri, amathanso kupirira mosavuta.

Kuphatikiza apo,kusankha mavavundi dongosolo lamphamvu loletsa kubwereranso, makamaka likagwiritsidwa ntchito pa kutentha kwakukulu.

mapeto

Pali mitundu yambiri ya ma valve pamsika, ndi zosankha zosiyanasiyana pansi pa kutentha kosiyana.Muyenera kufotokozera zomwe mukufuna komanso kutentha kwa valve yogwiritsidwa ntchito.Kenako sankhani valavu yomwe imakwaniritsa miyezo ndi zikhalidwe ndikukwaniritsa zofunikira zanu zonse.Mfundo zotsatirazi ndi nsonga ziyenera kuganiziridwa musanasankhe ma valve pansi pa kutentha kosiyana.
