Chitsulo cha mpiravalve yowunika madzindi mtundu wa valavu yomwe imagwiritsidwa ntchito mumayendedwe a mapaipi, omwe ntchito yake yayikulu ndikuletsa sing'anga kuti isabwererenso mu payipi, ndikuteteza pampu ndi mapaipi kuti asawonongeke ndi nyundo yamadzi. Chitsulo chachitsulo cha ductile chimapereka mphamvu zabwino kwambiri komanso kukana dzimbiri, zomwe zimapangitsa kuti zikhale zoyenera pakugwira ntchito zosiyanasiyana.

Mfundo yogwira ntchito ya ductile iron non return valve imachokera ku kusiyana kwa kuthamanga komwe kumapangidwa ndi kutuluka kwa sing'anga. Pamene sing'anga imayenda kutsogolo, valavu imatseguka, ndikulola madziwo kudutsa. Pamene sing'anga ikuyesera kuyenda mozungulira, mpira mkati mwa valavu umakankhidwira ku mpando wa valve pansi pa kupanikizika kwa sing'anga, motero kutseka valavu ndikulepheretsa sing'anga kubwereranso. Kapangidwe kameneka kamapangitsa kuti valve igwire ntchito popanda kufunikira kwa gwero lamphamvu lakunja.

Ubwino wa ductile iron non return check valve ndi:

1. Kapangidwe kameneka: Poyerekeza ndi ma valavu achikhalidwe, ma valve oyendera chitsulo amakhala ndi mawonekedwe afupikitsa, ma volume ang'onoang'ono, kulemera kwake, ndipo ndi osavuta kukhazikitsa ndi kusamalira.

2. Kusindikiza kwabwino: kugwiritsa ntchito zipilala za mpira wa pakhungu kuti zipereke zotsatira zabwino zosindikizira ndikuchepetsa kutayikira.

3. Kuzimitsa: Kuzimitsa kungathe kuchepetsa mafunde a nyundo ya madzi, kuchepetsa phokoso, ndi kuteteza mapaipi.

4. Kuvala kukana: Zomata zomata za chigawocho zimakhala ndi kusungunuka bwino komanso kuvala kukana, kukulitsa moyo wautumiki wa valve.

5. Kugwiritsa ntchito mwamphamvu: Itha kugwiritsidwa ntchito pazinthu zosiyanasiyana monga madzi ozizira, madzi otentha, zonyansa zamakampani ndi zapakhomo, ndipo ndizoyenera kuyika zopingasa kapena zowongoka.

6. Chepetsani mphamvu ya nyundo yamadzi: Mapangidwe a kutseka mwachangu amathandizira kuchepetsa nyundo yamadzi ndikuteteza dongosolo la mapaipi.

7. Kukonza kosavuta: magawo ochepa, kusungunula kosavuta, ndi kuchepetsa ndalama zosamalira.

Chifukwa chake, chifukwa cha kutentha kwakukulu, kuthamanga kwambiri, komanso malo owononga, valavu yachitsulo cha ductile 8 inchi imagwiritsidwa ntchito kwambiri m'makampani a petrochemical kuteteza kubweza kwapakatikati ndikuwonetsetsa chitetezo ndi kukhazikika kwa njira yopanga. Mu makina olowera ndi madzi opangira madzi a turbine ya nthunzi, ma ductile iron check valves amathanso kulepheretsa kutuluka kwa nthunzi ndi madzi odyetsa, kuteteza magwiridwe antchito a unit. Mafakitale ena akuphatikiza njira zoperekera madzi ndi ngalande zamatauni, mafakitale opanga mankhwala ndi mankhwala, makamaka m'makampani opangira madzi zachilengedwe. M'makina ochizira madzi, ma ductile iron check valves amatha kuteteza zimbudzi kuti zisabwerere ndikuwonetsetsa chitetezo chamadzi.

Vavu ya Jinbin yakhala ikugwira ntchito yopanga mavavu kwa zaka 20. Monga opanga ma valve aku China, timayang'ana kwambiri kafukufuku ndi chitukuko, kutsata zatsopano, ndikuyesetsa kupatsa makasitomala mayankho oyenera kwambiri. Zogulitsa zathu zazikulu zimaphatikizapo valavu ya zipata,valavu ya chipata cha sluice,valavu ya mpweya, mavavu akulu akulu akulu akulu, mavavu akulu akulu azipata, valavu yachitsulo chosapanga dzimbiri, ndi zina zambiri. Ngati muli ndi zosowa zokhudzana ndi valve, chonde titumizireni pansipa. Tikuyembekezera kugwira ntchito nanu!
