Masiku ano, mumsonkhano wa Jinbin, pali hydraulicvalavu ya chipata cha mpeniyokhala ndi kukula kwa DN1800 yapakidwa ndipo tsopano ikutumizidwa komwe ikupita. Chipata cha mpenichi chatsala pang'ono kuyikidwa chakumapeto kwa gawo lopangira magetsi opangira mphamvu yamadzi mu malo opangira magetsi opangira mphamvu yamadzi kuti akonze, kutanthauziranso miyezo yamakampani ndi magwiridwe ake apamwamba komanso kusinthasintha kwa malo.

Valve yachipata cha mpeni iyi yachita bwino kwambiri pakuchita bwino kwambiri. Thupi la valve limapangidwa ndi carbon steel Q355B, ndipo mbale ya valve imapangidwa ndi zitsulo zosapanga dzimbiri 304. Zimaphatikizidwa ndi zinthu zosindikizira za mphira wa nitrile, zomwe sizimangokwaniritsa kusindikiza kwa zero-kutuluka komanso kupitirira kutali ndi kukakamizidwa kwa zinthu wamba. Kuponyedwa zitsulo mpeni chipata valavu a m'mimba mwake chomwecho nthawi zambiri kokha kupirira mphamvu ya 1.5 makilogalamu ndi kusindikiza chisindikizo cha 1 kilogalamu, pamene mankhwala akhoza kupirira mphamvu ya 9 makilogalamu ndi kusindikiza chisindikizo cha 6 makilogalamu, kupereka chitsimikizo olimba ntchito yokonza pansi pa zinthu mkulu-anzanu.

Poyankha zovuta zogwirira ntchito za mavavu m'malo opangira magetsi a hydropower, luso lazopangapanga limaphatikiza kapangidwe ka bypass. Mavavu achikhalidwe akatsekedwa, kusiyana kwapakatikati pa mbali zonse ziwiri kumakhala kwakukulu, komwe kungayambitse zovuta pakutsegula. Komabe, kamangidwe kameneka kakhoza kuyambitsa kudutsa musanayambe kutsegula valavu yaikulu kuti muyese kupanikizika pamapeto onse awiri, kuchepetsa kwambiri kukana kwa ntchito ndi kupititsa patsogolo kukonza bwino.

Chomwe chikuyenera kuyang'aniridwa ndi dongosolo lake lokonzekera bwino malo. Poganizira malo ochepa oyikapo makasitomala aku Europe, gulu la R&D lidasiya kapangidwe ka ndodo zowoneka bwino ndikutengera mawonekedwe obisika, kulola ndodo ya pistoni ya silinda yamafuta kuti ilumikizidwe mwachindunji ndi mbale ya vavu, ndikuchotsa kufunikira kwa mabulaketi azikhalidwe. Izi zidachepetsa kutalika kwa zida zonse ndi osachepera 1.8 metres, zomwe zimagwirizana bwino ndi malo oyikapo.

Zatsopano zingapo za valavu yachipata chachikulu cha mpenizi sizimangokhudzanso zowawa pokonza malo opangira magetsi opangira magetsi, komanso zikuwonetsa kusinthasintha kwaukadaulo, zomwe zimapereka njira yatsopano yopangira zida zopangira magetsi opangira magetsi. Monga wopanga ma valve omwe ali ndi zaka 20, Valve ya Jinbin ili ndi chithandizo champhamvu chaukadaulo ndipo imapereka mayankho odalirika potengera zosowa zenizeni za makasitomala. Ngati muli ndi mafunso okhudzana ndi izi, chonde titumizireni pansipa ndipo mudzalandira yankho mkati mwa maola 24! (Mtengo wa Slide Gate Valve)
