Kusankha Kokhazikika: Mavavu a Mpira Wamagawo Atatu Okhazikika M'malo Opanikizika Kwambiri

Chisankho chokhazikika: Kuyang'ana mozama pamapangidwe a mavavu amipira atatu owotcherera komanso momwe amagwirira ntchito pamapulogalamu opanikizika kwambiri.

M'makina owongolera madzimadzi, ma valve a mpira akhala gawo lofunikira kwambiri pantchito zamafakitale chifukwa chosavuta kugwira ntchito, kapangidwe kake kophatikizana, komanso kusindikiza bwino. Monga mtundu wapadera wa valavu ya mpira, valavu yamagulu atatu ya welded yakhala ikudziwika kwambiri ndikugwiritsidwa ntchito chifukwa cha mawonekedwe ake abwino kwambiri komanso ntchito yabwino kwambiri pamagetsi apamwamba. Nkhaniyi ipereka kusanthula mozama kwa mawonekedwe a ma welded-piece-ball valves ndi momwe amagwirira ntchito pamapulogalamu apamwamba kwambiri.

1. Makhalidwe amapangidwe a valavu ya mpira wa welded wa magawo atatu

Vavu yamagulu atatu yowotcherera imapangidwa makamaka ndi zinthu zofunika kwambiri monga thupi la valavu, mpira, mpando wa valavu, tsinde la valve, ndi chisindikizo chonyamula. Chodziwika kwambiri ndi mawonekedwe ake a "zidutswa zitatu" komanso njira yolumikizira yolumikizira.

Kapangidwe ka magawo atatu: Thupi la valve la valavu yowotcherera yamagulu atatu limapangidwa ndi magawo atatu, omwe ndi mipando iwiri ya valve ndi thupi lapakati. Kapangidwe kameneka kamapangitsa kuti valavu ya mpira ikhale yowonjezereka pakupanga, ndipo zipangizo zosiyanasiyana ndi njira zimatha kusankhidwa malinga ndi zofunikira zenizeni kuti zigwirizane ndi malo osiyanasiyana ogwira ntchito ndi zofunikira zapakati. Panthawi imodzimodziyo, mapangidwe atatuwa amathandizanso kukonza ndi kukonzanso valavu, yomwe imatha kumalizidwa mwa kungochotsa mbali zina.
Njira yolumikizira kuwotcherera: Poyerekeza ndi njira yachikhalidwe yolumikizira flange, njira yolumikizira yowotcherera ili ndi kusindikiza kwakukulu komanso mphamvu. Kupyolera mu kuwotcherera, zigawo zikuluzikulu monga thupi la valve, mpira, ndi mpando wa valve zimagwirizanitsidwa kwambiri kuti zikhale zonse, kuteteza bwino kutayikira kwapakati ndi kuipitsidwa kwa kunja. Kuphatikiza apo, njira yolumikizira yolumikizira imachepetsanso kuchuluka kwa magawo olumikizira, kuchepetsa kulemera konse ndi voliyumu ya valve, ndikupangitsa kuti ikhale yaying'ono komanso yopepuka.

2. Magwiridwe a welded atatu-chidutswa mavavu mpira mu ntchito mkulu-anzanu

M'mapulogalamu opanikizika kwambiri, ma valve opangidwa ndi zidutswa zitatu amawonetsa magwiridwe antchito apamwamba chifukwa cha mawonekedwe awo apamwamba komanso magwiridwe antchito abwino kwambiri.

Kuthamanga kwamphamvu kwamphamvu: Valavu yamagulu atatu yowotcherera imapangidwa ndi zida zamphamvu kwambiri ndikuphatikizidwa ndi njira yolumikizira kuwotcherera, ndikupangitsa kuti ikhale yolimba kwambiri. Pamalo opanikizika kwambiri, valavu imatha kukhala yokhazikika yogwira ntchito, kuteteza bwino kutulutsa ndi kuwonongeka komwe kumachitika chifukwa cha kupanikizika kwambiri.
Kuchita bwino kwambiri kusindikiza: Mapangidwe osindikizira a valavu yamagulu atatu a welded amapangidwa mosamala kuti atsimikizire kuti zero kutayikira pamene valavu yatsekedwa. M'mapulogalamu apamwamba kwambiri, valavu imatha kupirira kupanikizika kwakukulu ndikukhalabe ndi ntchito yabwino yosindikiza, kuteteza bwino kutayikira kwapakatikati ndi kuipitsidwa kwakunja.
Kugwira ntchito kosasunthika: Kugwiritsiridwa ntchito kwa valavu ya mpira wa welded katatu ndi kosavuta komanso kosavuta, ndipo valavu ikhoza kutsegulidwa ndi kutsekedwa mwa kungotembenuza tsinde la valve. M'mapulogalamu apamwamba kwambiri, valve imakhalabe yogwira ntchito yokhazikika ndipo sichikhudzidwa ndi kusinthasintha kwa kuthamanga, kuonetsetsa kuti kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe kake kakuyenda bwino.
Ntchito zosiyanasiyana: Chifukwa valavu yowotcherera yamagulu atatu imakhala ndi mphamvu yolimbikitsira komanso kusindikiza bwino kwambiri, yakhala ikugwiritsidwa ntchito kwambiri pamapaipi apakati opatsirana kwambiri monga petroleum, makampani opanga mankhwala, ndi gasi. Kaya m'malo ovuta monga kutentha kwambiri, kuthamanga kwambiri, dzimbiri, ndi zina zotero, valavu yamagulu atatu yowotcherera imatha kugwira ntchito bwino.

3. Mapeto

Mwachidule, valavu yamagulu atatu yowotcherera yakhala gawo lofunikira kwambiri pamayendedwe amadzimadzi chifukwa cha mawonekedwe ake abwino kwambiri komanso magwiridwe antchito apamwamba kwambiri. M'tsogolomu, ndi kutuluka kosalekeza kwa zipangizo zatsopano ndi njira zatsopano, ntchito za ma valves a welded-piece-ball valves zidzapitilizidwa bwino, zomwe zikuthandizira kwambiri chitukuko cha mafakitale.
