Ngati valavu iyenera kusankhidwa kuti igwiritsidwe ntchito pa kutentha kwambiri, zinthuzo ziyenera kusankhidwa moyenerera. Zipangizo za mavalavu ziyenera kukhala zotha kupirira kutentha kwambiri ndikukhalabe zokhazikika pansi pa kapangidwe komweko. Mavalavu pa kutentha kwakukulu ayenera kukhala olimba. Zipangizozi zitha kukhala chitsulo chosapanga dzimbiri chapamwamba komanso chitsulo chosapanga dzimbiri cha mbali ziwiri. Zipangizo zotsika zomwe zingakhudze kutentha siziyenera kugwiritsidwa ntchito, apo ayi mavalavu osinthika kapena oyenda ayenera kupewedwa.

Kutentha kwambiri

Ma valve a gulugufe a throttle amatha kukhala okhazikika kutentha kwambiri. Kapangidwe kake ndithupi la valavuziyenera kuganiziridwa pamodzi ndi radiator kuti zikhoze kukonzedwa ndi zinthu zotenthetsera. Ngati valavu yaganiziridwa, zinthu za valavu sizili zokhazikika. Ngati kutentha kwapitirira malire omwe valavuyo ingapirire, sikungakhale koyenera valavu yanu.

Muyenera kuganizira ma valve okhala ndi mapaipi a ceramic kapena ma valve ena okhala ndi ma jekete ozizira kuti muchepetse zotsatira za kutentha. Ma jekete ozizira awa amagwira ntchito ndi kayendedwe ka madzi ozizira. Chifukwa chake, zinthuzomu valavuzidzakhala bwino popanda kupsinjika kulikonse.

Kutentha kochepa

Ngati kutentha kuli kotsika kwambiri, monga - 29℃, valavu yokhala ndi coefficient yotsika yokana kutentha iyenera kusankhidwa. Pa kutentha kotsika kwambiri kwa madigiri - 29 mpaka - 196 Celsius, chipolopolo ndi zinthu zomangira zimakhala zolimba mokwanira kuti zisunge kutentha ndikulinganiza zotsatira za kutentha kotsika kwambiri.

Mu kutentha kochepa kumeneku, muyenera kusankha valavu yokhala ndi zinthu zodzaza ndi gawo la thanki yamadzi kuti muzitha kuyang'anira kufunikira kwa kutentha. Kusankha mavalavu amenewa kumathandiza kuti kutentha kukhale kopitirira madigiri 0.℃.

Kusamala pa kutentha kosiyanasiyana

Pali chinthu chimodzi chosiyana ndi machenjezo a ma valavu. Pamene valavu yatsekedwa, madzi ena mu chipinda cha ma valavu adzakhalabe otsekedwa. Pakapita nthawi, madzi ena adzakhalabe mu chipinda cha ma valavu. Chifukwa chake, kutentha kudzayamwa pang'onopang'ono ndi mlengalenga ndipo kudzafikanso kutentha komweko, kapena kusungunuka mu chipinda cha ma valavu.

Izi zikachitika, voliyumu idzawonjezeka ndi nthawi pafupifupi 600, zomwe zimabweretsa kupanikizika kwakukulu ku thupi la valavu. Kupsinjika kwakukulu kumeneku kapena kupanikizika pa thupi la valavu kumatchedwa kuti kupanikizika kosayenera. Mkhalidwewu ndi wosalamulirika, kotero ukhoza kuyambitsa mavuto akulu a valavu ndipo ukhoza kukhala chifukwa chachikulu cha ngoziyi.

Pofuna kupewa izi zosasangalatsa za valavu pansi pa kutentha kosiyanasiyana, muyenera kusankha valavu yokhala ndi khomo lokhazikika bwino. Mtundu uwu wa valavu nthawi zambiri umagwiritsidwa ntchito pankhaniyi, ndipo njira iyi imagwiritsidwa ntchito kwambiri pankhaniyi.

zofunikira pakuchita bwino

Choyamba, muyenera kufotokoza zofunikira zonse za kutentha ndi kupanikizika. Muyenera kutchula kutentha ndi kupanikizika kwa valavu yomwe mukufuna kugwiritsa ntchito. Idzakuthandizani kusankha valavu yoyenera kutentha kosiyanasiyana. Tiyerekeze kuti mukufuna kugwiritsa ntchito valavu iyi kutentha kwambiri. Pankhaniyi, tikukulimbikitsani kugwiritsa ntchito valavu yachitsulo chifukwa imatha kupirira kutentha kwambiri kuposa chinthu china chilichonse. Ngati mpweya kapena kupanikizika kwamadzimadzi mu valavu kuli kokwera kwambiri, zimatha kupiriranso kupanikizika mosavuta.

Kuphatikiza apo,sankhani ma valvendi njira yolimba yopewera kubwerera kwa madzi, makamaka ikagwiritsidwa ntchito kutentha kwambiri.

mapeto

Pali mitundu yambiri ya ma valve pamsika, yokhala ndi zosankha zosiyanasiyana pansi pa mikhalidwe yosiyanasiyana ya kutentha. Muyenera kufotokoza zomwe mukufuna komanso kuchuluka kwa kutentha kwa valavu yomwe mungagwiritse ntchito. Kenako sankhani valavu yomwe ikukwaniritsa miyezo ndi zikhalidwe komanso ikukwaniritsa zofunikira zanu zonse. Mfundo ndi malangizo otsatirawa ayenera kuganiziridwa musanasankhe ma valve pansi pa mikhalidwe yosiyanasiyana ya kutentha.
