Chitsulo cha mpiravalavu yoyezera madzindi mtundu wa valavu yomwe imagwiritsidwa ntchito m'makina a mapaipi, yomwe ntchito yake yayikulu ndikuletsa kuti cholumikiziracho chisabwererenso mupaipi, pomwe chikuteteza pampu ndi makina a mapaipi kuti asawonongeke ndi nyundo yamadzi. Chitsulo chopangidwa ndi ductile chimapereka mphamvu zabwino kwambiri komanso kukana dzimbiri, zomwe zimapangitsa kuti chikhale choyenera kugwiritsidwa ntchito m'malo osiyanasiyana ogwirira ntchito.

Mfundo yogwirira ntchito ya valavu yosabwerera yachitsulo chosungunuka imachokera pa kusiyana kwa kuthamanga komwe kumachitika chifukwa cha kuyenda kwa sing'anga. Sing'anga ikayenda patsogolo, valavu imatseguka, zomwe zimapangitsa kuti madziwo adutse. Sing'anga ikayesa kuyenda mobwerera m'mbuyo, mpira womwe uli mkati mwa valavu umakankhira ku mpando wa valavu pansi pa kupanikizika kwa sing'anga, motero umatseka valavu ndikuletsa sing'anga kuti isabwerere m'mbuyo. Kapangidwe kameneka kamatsimikizira kuti valavu imagwira ntchito yokha popanda kufunikira mphamvu yakunja.

Ubwino wa valavu yowunikira chitsulo chopanda ductile ndi monga:

1. Kapangidwe kakang'ono: Poyerekeza ndi ma valve oyesera achikhalidwe, ma valve oyesera achitsulo chosungunuka amakhala ndi kutalika kwa kapangidwe kafupi, voliyumu yaying'ono, kulemera kopepuka, ndipo ndi osavuta kuyika ndi kusamalira.

2. Kugwira bwino ntchito yotseka chikopa: kugwiritsa ntchito zingwe za mpira wa rabara kuti zipereke zotsatira zabwino zotseka chikopa ndikuchepetsa kutuluka kwa madzi.

3. Kuzimitsa: Ikazimitsidwa, imatha kuchepetsa mafunde a nyundo yamadzi, kuchepetsa phokoso, komanso kuteteza makina a mapaipi.

4. Kukana kuvala: Chomatira cha bolodi chimakhala ndi kusinthasintha kwabwino komanso kukana kuvala, zomwe zimapangitsa kuti valavu ikhale ndi moyo wautali.

5. Kugwiritsa ntchito bwino: Itha kugwiritsidwa ntchito pazinthu zosiyanasiyana monga madzi ozizira, madzi otentha, zimbudzi zamafakitale ndi zapakhomo, ndipo ndi yoyenera kuyikidwa mopingasa kapena moyimirira.

6. Kuchepetsa mphamvu ya nyundo yamadzi: Kapangidwe ka kutseka mwachangu kumathandiza kuchepetsa vuto la nyundo yamadzi ndikuteteza dongosolo la mapaipi.

7. Kukonza kosavuta: zida zochepa, kusokoneza mosavuta, komanso kuchepetsa ndalama zokonzera.

Chifukwa chake, chifukwa cha kutentha kwambiri, kuthamanga kwambiri, komanso malo owononga, valavu yowunikira chitsulo cha ductile ya mainchesi 8 imagwiritsidwa ntchito kwambiri mumakampani opanga mafuta kuti apewe kubwerera kwapakati ndikuwonetsetsa kuti njira zopangira zinthu ndi zotetezeka komanso zokhazikika. Mu makina olowera ndi makina owunikira madzi a turbine ya nthunzi, mavalavu owunikira chitsulo cha ductile amathanso kuletsa kuyenda kwa nthunzi ndi madzi owunikira, kuteteza magwiridwe antchito abwino a chipangizocho. Makampani ena akuphatikizapo makina operekera madzi ndi ngalande za m'matauni, mafakitale a mankhwala ndi mankhwala, makamaka makampani osamalira madzi oteteza chilengedwe. Mu makina osamalira madzi, mavalavu owunikira chitsulo cha ductile amatha kuletsa bwino zinyalala kuti zisabwerere ndikuwonetsetsa kuti madzi ndi otetezeka.

Jinbin Valve yakhala ikugwira ntchito yopanga ma valve kwa zaka 20. Monga wopanga ma valve aku China, timayang'ana kwambiri kafukufuku ndi chitukuko, timatsata zatsopano, ndipo timayesetsa kupatsa makasitomala mayankho oyenera kwambiri. Zogulitsa zathu zazikulu zimaphatikizapo ma valve a zipata zopangidwa mwamakonda,valavu ya chipata cha sluice,valavu yopopera mpweya, ma valve akuluakulu a gulugufe, ma valve akuluakulu a chipata, valavu yotchinga yachitsulo chosapanga dzimbiri, ndi zina zambiri. Ngati muli ndi zosowa zokhudzana ndi ma valve, chonde titumizireni uthenga pansipa. Tikuyembekezera kugwira nanu ntchito!
