Posachedwapa, valavu ya Jinbin yamaliza kupanga mavalavu 6 a DN1600 a mpeni ndi mavalavu owunikira a butterfly a DN1600. Mavalavu onsewa ndi opangidwa ndi chitsulo.

Mu workshop, ogwira ntchito, mogwirizana ndi zida zokwezera, anaika valavu ya chipata cha mpeni yokhala ndi mainchesi a 1.6m ndi valavu yoyezera butterfly yokhala ndi mainchesi a 1.6m motsatana mgalimoto yopakira, kenako anaitumiza ku Russia.

Gulu la ma valve awa linalandira kuwunika kwa chipani chachitatu. Pofuna kutsimikizira chitetezo ndi kudalirika kwa ma valve, kuwonjezera pa mayeso a mphamvu ya ma valve pa kuthamanga kwa mayeso kwa nthawi 1.25 ~ 1.5 kuposa kuthamanga kwapadera asanachoke ku fakitale, khalidwe lakunja ndi khalidwe lamkati la malo opanda kanthu zinawunikidwanso. Valavu yathu yadutsa mayeso a chipani chachitatu, zida, kuthamanga ndi mayeso ena, ndipo yapambana mayesowo bwino.

Zofunikira za kasitomala ndizokwera kwambiri. Pamwamba pa chopoperacho pamafunika kukhala chosalala komanso choyera, makamaka ndi kapangidwe kokhuthala, ndipo sipadzakhala zolakwika monga ma pores, ma bowo ofooka, kumasuka, ming'alu ndi kukulunga mchenga. Kuti tikwaniritse zofunikira zomwe zili pamwambapa, njira zingapo ziyenera kutengedwa popopera, monga kusankha zipangizo zopopera zomwe zimalimbana ndi moto kwambiri komanso kuwongolera chinyezi cha mchenga wopopera. Popopera, iyenera kupakidwa m'magawo kuti itsimikizire kuuma kwa nkhungu ya mchenga, kugwiritsa ntchito njira yoyenera yothira ndi kukweza komanso kuwongolera mwachangu liwiro ndi kutentha kwa kuthira. Mulimonsemo. Chifukwa cha zofunikira zapamwamba zaukadaulo, njira yopopera ya valavu ndi yovuta kwambiri kuposa ya castings wamba. Kuti mupeze mtundu woyenera wa chinthu, castings yofananayo imafunikira chithandizo cha kutentha kuti ichotse kupsinjika mu ndondomeko yopopera. Nthawi yomweyo, X-ray, kuzindikira zolakwika za tinthu ta maginito, kuyang'anira kolowera ndi njira zina zodziwira zimagwiritsidwa ntchito.

Jinbin valve ndi kampani yopanga ma valve yomwe imagwira ntchito zaukadaulo pa kafukufuku ndi chitukuko, kupanga ndi kugulitsa, kuphatikiza sayansi, mafakitale ndi malonda. Imapanga makamaka ma valve a chipata cha mpeni, chipata cha penstock, ma valve a chipata chotsetsereka, ma valve a magalasi ndi zinthu zina zosiyanasiyana. Kwa zaka zambiri, kampani ya ma valve yakhala ikuyang'ana kwambiri pakupanga ma valve ndikutsatira zatsopano zodziyimira pawokha.
