Ubwino ndi Kugwiritsa Ntchito Ma Valves Opangidwa Ndi Mpira Wachitsulo

Mavavu opangidwa ndi zitsulo zopangira zitsulo amagwiritsidwa ntchito kwambiri m'mafakitale ambiri.Chifukwa cha ntchito yake yabwino kwambiri, imagwiritsidwa ntchito kwambiri mumitundu yosiyanasiyana yamadzimadzi monga mpweya, madzi, nthunzi, zowononga zosiyanasiyana, matope, mafuta, zitsulo zamadzimadzi komanso ma radioactive media.Koma kodi mukudziwa ubwino wa mavavu opangidwa ndi zitsulo zachitsulo?Ndiroleni ndikufotokozereni mwachidule.

1. Kukana kwamphamvu kwa vulcanization ndi kusweka.Zomwe zimapangidwa ndi valavu yachitsulo chopangidwa ndi chitsulo chokhudzana ndi sing'anga ndi zipangizo zamakono, zomwe zimagwirizana ndi mlingo wapadziko lonse.Pamwamba ndi faifi tambala-yokutidwa, amene angathe kukumana mkulu vulcanization ntchito.

2. Valavu yachitsulo yopangidwa ndi chitsulo imapangidwa ndi zinthu za polima kapena alloy, zomwe zimagonjetsedwa ndi kutentha kwakukulu ndi kuthamanga kwambiri, ndipo ndizoyenera kufalitsa ndi kugwedeza kwa mauthenga osiyanasiyana.Komanso, chifukwa cha zinthu zapaderazi, ili ndi kukana kwamphamvu kwa dzimbiri, moyo wautali komanso ntchito zambiri.

3. Sikuti valve yokhayo imapangidwa ndi zinthu zowonongeka, ngakhale mpando wa valve umapangidwa ndi chinthu chapadera, ndipo zinthuzo ndi PTFE zomwe zimakhala zopanda mankhwala pafupifupi mankhwala onse, kotero zimatha kusindikizidwa kwa nthawi yaitali.Chifukwa cha inertness yake yamphamvu, imakhala ndi magwiridwe antchito okhazikika, sizovuta kukalamba, ndipo imatha kugwiritsidwa ntchito kwa nthawi yayitali.

4. Nthawi zambiri, valavu yachitsulo yopangidwa ndi chitsulo imakhala yofanana, kotero imatha kupirira kupanikizika kwapaipi kwamphamvu, ndipo malowo ndi ovuta kusintha.Inachita bwino kaya inali yotsegula kapena yotsegula.Kusindikiza kwabwino komanso sikumamatira ponyamula zakumwa za viscous.

Zomwe zili pamwambazi ndi zina za ma valve opangidwa ndi zitsulo zachitsulo.Ngakhale kuti sizinthu zonse zomwe zalembedwa pamwambapa, omwe ali mumakampani amadziwa kuti iyi ndi valve yomwe imagwira ntchito bwino.Ngati kampani yomwe ikugwiritsa ntchito zoyendera zamadzimadzi ikufunikanso kukhazikitsa valve, itha kuganiziridwa.
