Mu malo ochitira masewera a Jinbin, gulu la zikwamamavavu a gulugufeyamalizidwa. Imatchedwanso LTvalavu ya gulugufe ya kalembedwe ka lug, yokhala ndi kukula kwa DN400 komanso yokhala ndi ma actuator opumira. Tsopano ayamba mayendedwe ndipo akupita ku Saudi Arabia.

Valavu ya gulugufe ya LT lug ndi valavu yomwe imagwiritsidwa ntchito kwambiri m'makina amadzimadzi apakati komanso otsika mphamvu. Ubwino wake waukulu ndi monga kukhazikitsa kosinthasintha, kutseka kodalirika komanso kukana kuyenda kwa madzi pang'ono, zomwe zimapangitsa kuti ikhale yoyenera kuwongolera kayendedwe ka madzi m'mikhalidwe yosiyanasiyana yogwirira ntchito. Ma valavu omwe ali kumapeto konse kwa thupi la valavu amatha kukhazikika kudzera m'mabotolo popanda kudalira kulemera kwa flange ya chitoliro, ndipo amagwirizana ndi miyezo yosiyanasiyana ya flange monga ANSI ndi GB. Pokonza, thupi la valavu limatha kusweka padera popanda kukhudza dongosolo la payipi ndi mapaipi, zomwe zimapangitsa kuti ntchito yokonza ikhale yogwira mtima kwambiri.

Thupi la valavu lili ndi kapangidwe kakang'ono ndipo limalemera 1/3 mpaka 1/2 yokha ya valavu ya chipata ya specification yomweyo. Njira yoyendera ndi yopanda chopinga ndipo ili pafupi ndi mtundu wowongoka, yokhala ndi coefficient yaying'ono yokana kuyenda, yomwe ingachepetse kugwiritsa ntchito mphamvu poyendetsa. Imathandizira kuyendetsa kwamanja, kwamagetsi kapena kwampweya, yokhala ndi torque yaying'ono yosinthira, zomwe zimapangitsa kuti ikhale yoyenera pazochitika zazikulu (DN50-DN2000).

Valavu ya gulugufe ya mtundu wa LT imagwiritsidwa ntchito kwambiri pazochitika zotsatirazi:

1. Kupereka madzi ndi ngalande ndi kukonza madzi: Ma network operekera madzi ndi ngalande za m'matauni, malo oyeretsera zinyalala, malo oyeretsera madzi, omwe amagwiritsidwa ntchito ponyamula ndi kuletsa madzi oyera, zinyalala ndi madzi obwezeretsedwa. Mtundu wofewa wotsekedwa ukhoza kukwaniritsa zofunikira zochepa zotayikira madzi ndipo ndi woyenera kuyenda kwakukulu.

2. Makampani Opanga Mafuta ndi Ogulitsa: Kutumiza zinthu monga mafuta osakonzedwa, zinthu zopangidwa ndi mafuta oyeretsedwa, zinthu zosungunulira mankhwala, njira zoyeretsera asidi ndi alkali, ndi zina zotero. Mtundu wotsekedwa bwino umatha kugwira ntchito kutentha kwapakati komanso kupanikizika, ndipo njira yoyika lug ndiyoyenera kusamalira mapaipi a mankhwala pafupipafupi.

3. Makina a Hvac ndi nyumba: Kuyenda kwa madzi oziziritsa mpweya pakati, maukonde otenthetsera pakati, makina amadzi ozizira m'mafakitale. Mtundu wofewa wotsekedwa uli ndi mphamvu yabwino yotseka, ndi woyenera kugwira ntchito pa kutentha kochepa komanso kotsika, ndi wosavuta kugwiritsa ntchito komanso wosunga mphamvu, ndipo umachepetsa mtengo wogwirira ntchito wa makinawo.

4. Makampani Omanga Zombo ndi Zachitsulo: Makina amadzi oyenda pansi pa sitima, madzi ozizira mumakampani opanga zitsulo, mapaipi onyamula mpweya wopanikizika. Kapangidwe ka thumba kamakhala ndi mphamvu yolimbana ndi kugwedezeka ndipo ndi koyenera kuyika malo ovuta monga zombo zokhala ndi mabowo kapena malo opangira mafakitale.
