Posachedwapa, angapoma valve otsekedwa akhunguZamalizidwa mu workshop ya Jinbin Valve. Ndi kukula kwa DN700, kuthamanga kogwira ntchito kwa PN10, zimapangidwa ndi chitsulo cha kaboni cha Q235B.

Mtundu wotsekedwavalavu ya magalasi(DN700 carbon steel type) imatsegula ndi kutseka mapaipi kudzera mu kusintha kwa "open/blind" kwa valavu. Pakagwira ntchito, makina oyendetsa amayamba kutulutsa pamwamba pa valavu, zomwe zimathandiza kuti valavu isunthe molunjika kuti igwirizane ndi dzenje lolowera kapena dzenje losawona ndi payipi. Ikayikidwa pamalo ake, pamwamba pa valavu imamangidwanso kuti ipange kusungulumwa kosataya madzi. Malo otsekera sakhudzana mwachindunji potsegula ndi kutseka, zomwe zimachepetsa kwambiri kuwonongeka ndikutsimikizira kutseka kodalirika kwa nthawi yayitali.

Poyerekeza ndi ma valve wamba, amatha kusiyanitsa mapaipi kwathunthu, zomwe zimathandiza kwambiri pakusamalira mapaipi omwe amanyamula zinthu zoopsa. Chitsulo cha kaboni ndi choyenera kugwiritsa ntchito zinthu zopanda poizoni komanso zowononga pang'ono, zomwe zimakhala zotsika mtengo komanso zolimba kwambiri, zomwe zimapangitsa kuti zikhale zoyenera kugwiritsidwa ntchito ndi mainchesi akuluakulu monga DN700. Kuphatikiza apo, zimakhala ndi kuwonongeka kochepa panthawi yogwira ntchito, kapangidwe kotsekedwa mokwanira kuti kachepetse dzimbiri lakunja kwa nthawi yayitali, komanso kuthandizira magetsi/hydraulic actuation kuti agwiritsidwe ntchito patali. Izi zimachotsa kufunikira kwa ogwira ntchito kulumikizana mwachindunji ndi zinthu zoopsa, zomwe zimapangitsa kuti zikhale zoyenera kugwiritsidwa ntchito pamakina odziyimira pawokha.

Ma valve amenewa amagwiritsidwa ntchito kwambiri mumakampani opanga zitsulo pokonza mpweya wophulika ndi mapaipi a gasi a coke, kupewa kutulutsa kwa mpweya woopsa komanso kuonetsetsa kuti maukonde a ng'anjo ndi mapaipi ndi otetezeka. Amagwiritsidwanso ntchito m'magawo oteteza mankhwala ndi chilengedwe potsegula/kutseka mapaipi omwe amanyamula zinthu zowononga komanso zoyaka/zophulika monga mpweya wa chlorine, ammonia, ndi mpweya wotuluka m'mafakitale. Kuphatikiza apo, amagwira ntchito ngati zida zofunika kwambiri zozimitsira mpweya m'maboma ndi m'makampani opanga magetsi, mpweya wotuluka m'mafakitale, ndi machitidwe oyeretsera madzi otayira, omwe amagwiritsidwa ntchito pokonza mapaipi kapena kuwachotsa mwadzidzidzi.

Monga wopanga ma valve apadera a makampani opanga zitsulo, Jinbin Valve imapanga mitundu yosiyanasiyana ya ma valve akhungu, kuphatikizapo ma valve akhungu otseguka, ma valve akhungu otsekedwa, ndi ma valve akhungu opanikizika kwambiri, omwe amatha kusinthidwa malinga ndi momwe ntchito ikuyendera. Ngati muli ndi zosowa zilizonse zofunika, chonde siyani uthenga pansipa kapena titumizireni imelo patsamba loyamba, ndipo mudzalandira yankho mkati mwa maola 24!
