Makuru-diameter flange anoshandiswa zvakanyanya muindasitiri yemuchina

Abstract: Ichi chinyorwa chinosuma mamiriro anoshanda uye maitiro ekugadzira ehombe-diameter flanges.

Makuru-diameter flanges anoshandiswa zvakanyanya, uye chiyero chekushandisa chinotemerwa nehunhu hwavo. Iwo anonyanya kushandiswa mukudzika-kudzvanywa (nominal pressure haipfuure 2.5MPa) isina-yakacheneswa yakamanikidzwa mweya, yakaderera-inotenderera inotenderera mvura uye zvimwe zviitiko zvine yakasununguka midhiya mamiriro, uye ine mukana wekuve wakachipa. Zvishandiso ndezvekabhoni simbi, simbi isina tsvina uye alloy simbi, nezvimwe.

Mafurange akakura-dhayamita akajairika anosanganisira flat welding flanges uye butt welding flanges, uye mahombe-diameter akarukwa maflange haanyanyo shomeka. Mukugadzirwa chaiko uye kutengesa, flat welding zvigadzirwa zvichiri kuverengera chikamu chikuru. Flat welding hombe-diameter flanges uye butt welding hombe-diameter flanges ine zvimiro zvakasiyana uye mashandisiro ekushandisa, uye hunhu uye zvakanakira zvinogona kuratidzwa zvichave zvakasiyana. Naizvozvo, kana uchiashandisa, iwo anofanirwa kushandiswa kune akasiyana siyana kuti ave nechokwadi chekuti flange inoita basa rakakosha. Yakakura-diameter flat welding flanges ine hutsika husina kusimba uye inokodzera zviitiko zvine pressure p≤4MPa; mahombe-diameter butt welding flanges anonziwo mahombe-diameter akakwira-mitsipa maflange, ayo ane kusimba kukuru uye akakodzera kune dzimwe nguva nekumanikidza kwakanyanya uye tembiricha.

Kune marudzi matatu ehombe-diameter flange yekuisa chisimbiso nzvimbo:

1. Flat sealing surface, yakakodzera kune dzimwe nguva dzine low pressure uye non-chepfu media;

2. Concave uye convex yekuisa chisimbiso pamusoro, inokodzera nguva dzinenge dzakakwirira zvishoma;

3. Tenon uye groove sealing surface, yakakodzera kupisa, kuputika, huturu hwezvenhau uye nguva dzekumanikidzika. Flange pombi fittings yezvivakwa zvakasiyana zvine mashandiro akanaka echigadzirwa munzvimbo dzakasiyana, uye mhedzisiro inogadzirwa ichave yakasiyana zvichienderana nezviitiko uye nzvimbo dzavanokodzera.

Iyo nzira yekugadzira yakakura-diameter Stainless simbi flanges yakakamurwa kuita rolling uye forging

Rolling process: Nzira yekucheka mitsetse kubva mundiro yepakati uye wozoitenderedza kuita denderedzwa inodaidzwa kuti rolling, iyo inonyanya kushandiswa mukugadzira mamwe maflange makuru esimbi asina tsvina. Mushure mekunge kukunguruka kwabudirira, welding inoitwa, yobva yaita flatten, uyezve nzira yemvura uye bolt hole inogadziriswa.

Mafurange akafukidzwa mahombe-dhayamita anowanzo ane yakaderera kabhoni pane mahombe-dhayamita akakandwa maflange, haasi nyore kuita ngura, ane mafogi akakwenenzverwa, akanyanya kusimba muchimiro, ane zvirinani zvemuchina pane mahombe-dhayamita akakandwa maflange, uye anogona kumira kugera kwakakwira. uye tensile forces

Maitiro ekugadzira anowanzo ane nhanho dzinotevera, dzinoti, kusarudza emhando yepamusoro simbi mabheti ekuputira, kudziyisa, kuumba, uye kutonhora mushure mekugadzira. Maitiro ekuforoma anosanganisira mahara forging, kufa forging uye membrane forging. Munguva yekugadzira, nzira dzakasiyana dzekuumba dzinosarudzwa zvichienderana nemhando yefogi uye huwandu hwemabheti ekugadzira.

Yemahara forging ine yakaderera chibereko uye yakakura machining mvumo, asi maturusi ari nyore uye anoshanda zvakasiyana, saka anoshandiswa zvakanyanya kugadzira zvidimbu zvimwechete uye madiki mabhechi efogi ane akareruka maumbirwo. Yemahara forging michina inosanganisira sando dzemhepo, sando dzemhepo-yemhepo uye hydraulic presses, izvo zvakakodzera kugadzirwa kwediki, epakati uye hombe forgings zvichiteerana.

Model forging ndeyekuisa iyo inopisa billet mufogi yefogi yakagadzikwa pane inofa yekugadzira michina yefogi. Die forging ine kugadzirwa kwakanyanya, kushanda kuri nyore, uye kuri nyore kugadzira uye otomatiki. Die forgings ine yakakwira dimensional kurongeka, diki machining mvumo, uye inonzwisisika faibha chimiro kugovera kwe forgings, iyo inogona kuwedzera kuvandudza hupenyu hwesevhisi yezvikamu.
