B367 Gr.C-2 Worm Gear Ogwira Ntchito ya Trunnion Mounted Ball Valve
Mapangidwe a ma valve a mpira opangidwa ndi titaniyamu aloyi zida makamaka zikuphatikizapo zigawo zikuluzikulu monga ma valve ma valve, zophimba valavu, valavu zimayambira, mabwalo, ndi valavu mipando. Chodziwika kwambiri cha titaniyamu alloy mpira mavavu ndi kukana kwawo kwa dzimbiri, komwe kumatha kugwira ntchito bwino pama media osiyanasiyana owononga monga ma acid amphamvu, ma alkali amphamvu, ndi mchere. Kuphatikiza apo, ilinso ndi zabwino monga kukana kutentha kwambiri, kukana kuvala, komanso kulemera pang'ono, zomwe zimapangitsa kuti azigwiritsidwa ntchito kwambiri m'mafakitale monga mafuta, mankhwala, zitsulo, ndi mphamvu. Mfundo yake yogwiritsira ntchito ndikugwiritsa ntchito tsinde la valve kuyendetsa kuzungulira kwa mpira, kupanga njira zosiyanasiyana pakati pa mpira ndi mpando wa valve, potero kukwaniritsa kutsegula, kutseka, ndi kusintha kwapakati. Pamene gawolo likuzungulira madigiri 90, sing'anga imadutsa mu valve; Chigawochi chikazungulira madigiri a 180, sing'angayo imadulidwa kwathunthu. Kusindikiza kwake kumadalira makamaka malo olumikizana pakati pa gawo ndi mpando wa valve komanso momwe zinthu zosindikizira zimagwirira ntchito.

Zina Zowonjezera
1. Mpira umathandizidwa ndi mayendedwe apamwamba ndi otsika, kuchepetsa kukangana ndikuchotsa torque yochulukirapo yopangidwa ndi katundu wamkulu wosindikiza wopangidwa ndi kukakamiza kolowera kukankhira mpira ndi mpando wosindikiza.
2. Mphete yosindikizira ya PTFE imodzi imayikidwa pampando wa valve yachitsulo chosapanga dzimbiri, ndipo kasupe amaikidwa kumapeto kwa mpando wa valve wachitsulo kuti atsimikizire kuti mphete yosindikizira ili ndi mphamvu yokwanira yomangirira. Ngakhale malo osindikizira atha kugwira ntchito, amatha kutsimikizira kuti ntchito yabwino yosindikiza ikugwira ntchito masika.
3. Pofuna kupewa kuchitika kwa moto, mphete yosindikizira yamoto imayikidwa pakati pa gawo ndi mpando wa valve. Pamene mphete yosindikizira itenthedwa, pansi pa mphamvu ya masika, mphete yosindikizira ya mpando wa valve imakankhidwira mofulumira kumtunda, kupanga chitsulo ku chisindikizo chachitsulo, kukwaniritsa kusindikiza kwina. Kuyesa kukana moto kumakwaniritsa zofunikira za APl6FA ndi APl607.
4. Pamene kukakamiza kwa sing'anga yotsekeredwa mu chipinda cha valve kumawonjezeka mosadziwika bwino kupitirira kuthamanga kwa kasupe, mpando wa valve umabwereranso ndikuchoka pamtunda, zomwe zimapangitsa kuti pakhale mpumulo. Pambuyo pakupanikizika, mpando wa valve udzachira
5. Mabowo okhetsa amayikidwa mbali zonse za thupi la valavu kuti awone ngati pali kutayikira pampando wa valve. Panthawi yogwira ntchito, valavu ikatsegulidwa kapena kutsekedwa kwathunthu, kupanikizika mkati mwa chipinda chapakati kumatha kuchotsedwa ndipo kunyamula kungasinthidwe mwachindunji; Ikhoza kutulutsa zinthu zotsalira m'chipinda chapakati ndikuchepetsa kuipitsidwa kwa sing'anga pa valve.
6.Chifukwa cha zinthu zakunja pakatikati kapena pamoto zomwe zimayambitsa kulephera mwangozi kwa chisindikizo cha mpando wa valve, valavu yamafuta imapereka kulumikizana mwachangu ndi mfuti yamafuta, ndipo pampu yotumizidwa kunja mosavuta komanso mwachangu imalowetsa mafuta osindikizira m'malo osindikizira mpando wa valve kuti muchepetse kutayikira.
7. Kuphatikiza pa kukhazikitsa mphete zosindikizira zokhazikika, zisindikizo za O-ring zimayikidwanso pa gland yonyamula, kuonetsetsa kudalirika kwa chisindikizo cha valve tsinde ndi kusindikiza kawiri; Kuwonjezeredwa kwa graphite kulongedza ndi kusindikiza jekeseni wamafuta kumachepetsa kutuluka kwa tsinde la valve pambuyo pa moto. Ma bere otsetsereka ndi mayendedwe opondereza a tsinde la valavu amapangitsa kuti valavu ikhale yosavuta.
8. Mitundu yoboola kapena yocheperako imatha kusankhidwa ngati pakufunika. Kubowola kwa valavu yodzaza kumagwirizana ndi kukula kwapakati kwa payipi, zomwe zimapangitsa kuti paipiyo ikhale yosavuta kuyeretsa.
9 . Malingana ndi zofunikira za kukhazikitsa kapena ntchito, tsinde la valve likhoza kukulitsidwa. Vavu yowonjezedwa ya mpira, makamaka yoyenera gasi wakutawuni ndi zochitika zina zomwe zimafunikira kuyika mapaipi okwiriridwa. Kukula kwa tsinde la valve yowonjezera kudzatsimikiziridwa malinga ndi zosowa za makasitomala.
10. Kugwiritsiridwa ntchito kwa mipando ndi tsinde yokhala ndi coefficient yaing'ono yolimbana ndi zinthu zabwino zodzipaka mafuta kumachepetsa kwambiri torque yogwiritsira ntchito valve. Choncho, ngakhale popanda kupereka mafuta osindikizira, valavu imatha kugwiritsidwa ntchito mosinthasintha komanso momasuka kwa nthawi yaitali.

Kukonzekera kwa titaniyamu alloy valves.
Kuti zitsimikizire kuti zimagwira ntchito bwino komanso moyo wautumiki, valve iyenera kusamalidwa nthawi zonse.
1. Yang'anani nthawi zonse maonekedwe a valve kuti muwonetsetse kuti alibe chilema, kuwonongeka, ndi zina.
2. Nthawi zonse muzipaka valve kuti muchepetse mikangano pakugwira ntchito kwa valve ndikuwonjezera moyo wake wautumiki.
3. Nthawi zonse muzitsuka valve kuti muchotse dothi, madipoziti, etc. pamwamba pa valve ndikuonetsetsa kuti ntchito yake yosindikiza ikugwira ntchito.
4. Nthawi zonse yesetsani kuyesa ma valve kuti muwonetsetse kuti kusindikiza ndi chitetezo chawo kumakwaniritsa zofunikira.
Mwachidule, ma valve a mpira wa titaniyamu akhala akugwiritsidwa ntchito kwambiri m'mafakitale ambiri chifukwa cha kukana kwawo kwa dzimbiri, kukana kutentha kwambiri, kukana kuvala, ndi zina. Kumvetsetsa zidziwitso zoyenera za titaniyamu alloy mpira mavavu kungatithandize kusankha bwino ndi kugwiritsa ntchito valavu yapamwambayi, kukonza bwino kupanga ndi chitetezo.
