Masiku ano, DN1200-kakulidwevalavu yopendekera yokhala ndi nyundo yolemetsamu msonkhano wa Jinbin wamaliza ntchito yonse yopanga ndipo ikugwira ntchito yomaliza yonyamula, yomwe yatsala pang'ono kutumizidwa kwa kasitomala. Kutha bwino kwa madzi awachekeni valavusikuti amangowonetsa njira zopangira zopangira zogwirira ntchito, komanso zikuwonetsa kufunika kofunikira kwa ma valve akulu akulu-kukaniza otsekeka pang'onopang'ono m'malo owongolera madzi amadzimadzi.

Ma valavu akulu akulu, okhala ndi mawonekedwe ake apadera, ali ndi zinthu zingapo zodziwika. Choyamba, mphamvu yothamanga kwambiri ndiye phindu lake lalikulu. DN1200 flanged check valve imatha kukwaniritsa zofunikira za kayendedwe ka madzimadzi othamanga kwambiri, ndi kuchepa kwapang'onopang'ono panthawi ya kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe kake. Kachiwiri, imakhala ndi kukhazikika kwadongosolo. Zopangidwa ndi zida zamphamvu kwambiri, thupi la valve liri ndi makulidwe a khoma lofanana ndipo limatha kupirira zovuta zogwirira ntchito monga kuthamanga kwambiri komanso kutentha kwambiri. Utumiki wake umaposa kwambiri wa agulugufe. Kuphatikiza apo, ma valavu akulu akulu ali ndi ntchito yabwino yosindikiza. Kupyolera mu ndondomeko yolondola ya malo osindikizira ndi pachimake cha valve, amatha kuchepetsa kubwereranso kwapakati pamlingo waukulu ndikuwonetsetsa kuti dongosololi likuyenda bwino.

Monga gulu lapamwamba kwambiri pakati pa valavu yachitsulo chachitsulo chachikulu, valavu yotsekera pang'onopang'ono imakhala ndi ntchito zosasinthika m'magawo angapo. M'mapulojekiti operekera madzi akumidzi, amayikidwa kwambiri pamapaipi akuluakulu otumizira madzi a zomera zamadzi. Sizingangokwaniritsa kuchuluka kwa madzi ofunikira panthawi yanthawi yayitali komanso kuteteza nyundo yamadzi kudzera pakutseka kwake pang'onopang'ono, kuteteza mapaipi ndi zida zopopera. M'makina ozungulira amadzi amagetsi otenthetsera magetsi, valavu yosabwererayi imatha kuyang'anira komwe akutumiza madzi ozizira, kuletsa kubweza kwamadzi panthawi yotseka, ndikuwonetsetsa kuti makina opangira magetsi atsekedwa. M'mafakitale akuluakulu ochotsera zinyalala, mapangidwe osagwirizana ndi dzimbiri amatha kusinthana ndi zovuta za media media. Pakadali pano, ntchito yotseka pang'onopang'ono imatha kuchepetsa kugwedezeka kwa mapaipi ndikuchepetsa mtengo wokonza zida.

Ngati mukufunikiranso kusintha ma valve akulu akulu, chonde titumizireni pansipa. Mudzalandira yankho mkati mwa maola 24 ndipo tidzasintha njira yabwino kwa inu m'modzi-m'modzi.
