Flanged (Fixed) Ball Valve

Zowonetsa Zamalonda

Q47 mtundu wokhazikika wa valavu ya mpira poyerekeza ndi valavu yoyandama ya mpira, ikugwira ntchito, kuthamanga kwamadzimadzi kutsogolo kwa gawo la zonse kumadutsa ku mphamvu yonyamula, sikungapange bwalo kumpando kusuntha, kotero mpando sudzaberekanso. kupanikizika kwambiri, kotero kukhazikika kwa valve valve torque ndi yaying'ono, mpando wa mapindikidwe ang'onoang'ono, ntchito yosindikizira yokhazikika, moyo wautali wautumiki, womwe umagwiritsidwa ntchito ndi kuthamanga, kuthamanga kwakukulu. .Vavu iliyonse ili ndi mipando iwiri ndipo imatha kusindikizidwa kumbali iliyonse, motero unsembe ulibe zoletsa zoyenda.Ndi mbadwo watsopano wa valve yothamanga kwambiri, valavu ya mpira wa flange ndi yoyenera mapaipi aatali ndi mapaipi ambiri a mafakitale, mphamvu zake, chitetezo. , kukana chilengedwe chokhwima pakupanga kulingalira kwapadera, koyenera kuzinthu zosiyanasiyana zowonongeka komanso zosawononga.
Flanged fixed mpira valve ntchito mfundo:
Mpira wa valve yokhazikika yokhazikika imakhazikika ndikuthandizidwa ndi zingwe ziwiri zokhazikika zolumikizidwa ndi mpira. Mukatsekedwa, pansi pa kupanikizika kwapakati, mpirawo sudzatulutsa kusuntha, komwe nthawi zambiri kumalumikizidwa ndi mpira pamtunda wapamwamba, wapansi. shaft imakhala ndi ma bearings ogudubuza, kapena mayendedwe otsetsereka.Kuchepetsa kugunda kwa magazini pamene mukutsegula ndi kutseka.Chepetsani torque yogwiritsira ntchito.Mpira wokhazikika uwu ndi woyenerera ma valve akuluakulu a mpira.Q47 chosindikizira cholimba chosindikizira mpira wokhazikika. tsinde la valve iwiri yokhazikika.Pamene akugwira ntchito, kuthamanga kwamadzimadzi sikungapangitse mpira ku kayendetsedwe ka mpando wa valve, mpando wa valve sudzakhala ndi kupanikizika kwambiri ndi kusokoneza. torque yosinthira ndi yaying'ono. Mipando yonse ya valve imayikidwa kale ndi kasupe.Chisindikizocho chimatenga PTFE choyikidwa muzitsulo zachitsulo, ndipo kasupe amaperekedwa kumbuyo kwa mphete yachitsulo kuti atsimikizire kuti mpando wa valve uli pafupi ndi mpira. mosadziwika bwino komanso kupitilira mphamvu yothamangitsa kasupe, mpando wa valve umachotsedwa pa mpira kuti ukwaniritse zotsatira za kupanikizika kwadzidzidzi, ndipo mpando wa valve umakhazikitsidwanso pambuyo pa kupanikizika. -kupulumutsa ndi moyo wautali wautumiki. Ndiwoyenera kwambiri pamapaipi aatali komanso mapaipi ambiri.
