Flanged connection inhengo yevharuvhu ine maflange kumagumo ese, inoenderana nemaflange ari papombi, nekusunga flange yakaiswa mupombi. Flanged connection ndiyo inonyanya kushandiswa mhando yevhavha yekubatanidza. Flanges ine convex (RF), ndege (FF), convex uye concave (MF) uye mamwe mapoinzi. Zvinoenderana nechimiro chejoint surface, inogona kukamurwa kuva anotevera marudzi:
(1) mhando yakatsetseka: yevharuvhu ine yakaderera kudzvanywa. Processing iri nyore;
(2) concave uye convex mhando: yakakwirira kushanda kumanikidzwa, anogona kushandisa yakaoma gasket;
(3) tenon groove type: gasket ine hombe yepurasitiki deformation inogona kushandiswa zvakanyanya mune inoora midhiya, uye yekuisa chisimbiso iri nani;
(4) trapezoidal groove mhando: oval simbi mhete se gasket, inoshandiswa muvharuvhu kushanda kumanikidza ≥64 kg/cm2, kana yakakwirira tembiricha vharafu;
(5) Lens type: gasket riri muchimiro chelenzi, rakagadzirwa nesimbi. Inoshandiswa kune yakakwirira mavharuvhu ane kushanda nesimba ≥ 100kg/cm2, kana tembiricha mavharuvhu;
(6) O-ring mhando: iyi inzira nyowani yekubatanidza flange, iri nekubuda kwemarudzi ese erubha O-ring, uye yakagadziridzwa, inovimbika zvakanyanya mukuisa chisimbiso pane general flat gasket.
(1) Butt-welding connection: migumo yese yevharuvhu inogadziridzwa kuita butt-welding groove zvinoenderana nezvinodiwa zvebutt welding, zvinoenderana nepombi welding groove, uye yakamiswa papombi kuburikidza newelding.
(2) socket welding yekubatanidza: ese magumo emuviri wevharuvhu anogadziriswa zvinoenderana nezvinodiwa socket welding uye akabatana nepombi kuburikidza nesocket welding.
Threaded yekubatanidza inzira iri nyore yekubatanidza uye inowanzoshandiswa kune mavharuvhu madiki. Muviri wevharuvhu unogadziriswa zvinoenderana neshinda yakajairwa, uye kune marudzi maviri eshinda yemukati nekunze. Zvinoenderana neshinda papombi. Threaded connection yakakamurwa kuva mamiriro maviri:
(1) chisimbiso chakananga: tambo dzemukati nekunze dzinotamba zvakananga basa rekuisa chisimbiso. Kuti uone kuti mubatanidzwa haudonhe, kazhinji nemafuta ekutungamirira, hemp uye PTFE raw material yekuzadza bhandi; Pakati pavo, PTFE raw material bhandi rinoshandiswa zvakanyanya. Ichi chinyorwa chine kunaka kwekusagadzikana kwekuora, kuvharisa kwakanakisa, nyore kushandisa uye kuchengeta, kana disassembly, inogona kubviswa zvachose, nekuti iyo dhizaini yeasina-viscous firimu, zviri nani pane lead mafuta, hemp.
(2) kuiswa chisimbiso kusina kunanga: simba rekusimbisa screw rinoendeswa kune gasket pakati pezvikepe zviviri, kuitira kuti gasket iite basa rekuvhara.
Kune marudzi mashanu eshinda dzinowanzo shandiswa:
(1) Metric common thread;
(2) Masendimita anowirirana;
(3) Thread sealing pipe thread;
(4) shinda isina shinda yekuisa chisimbiso chepombi;
(5) American standard pombi shinda.
General sumo ndeiyi inotevera:
① International standard ISO228/1, DIN259, yemukati nekunze yakafanana shinda, kodhi G kana PF(BSP.F);
② German standard ISO7/1, DIN2999, BS21, yekunze zino koni, remukati mazino parallel shinda, code BSP.P kana RP/PS;
③ British mwero ISO7/1, BS21, yemukati nekunze taper shinda, kodhi PT kana BSP.TR kana RC;
④ American standard ANSI B21, yemukati nekunze taper shinda, kodhi NPT G(PF), RP(PS), RC (PT) zino Engle i55°, NPT zino Engle i60°BSP.F, BSP.P uye BSP. TR pamwe chete inonzi BSP mazino.
Kune marudzi mashanu eshinda dzepombi dzakajairwa muUnited States: NPT yekushandiswa kwese, NPSC yetambo dzepombi dzemukati dzakatwasuka dzemafittings, NPTR yekubatanidza tsvimbo yegwara, NPSM yetambo dzakatwasuka dzepombi dzekubatanidza michina (yemahara fit mechanical connections), uye NPSL. for loose fit mechanical connections with locking nzungu. Ndeyeshinda isina shinda yakavharwa pombi (N: American national standard; P: pombi; T: Taper)
4 .Taper connection
Kubatana uye chisimbiso musimboti we sleeve ndeyekuti kana nut yakasimbiswa, sleeve iri pasi pekumanikidzwa, kuitira kuti mupendero upinde mumadziro ekunze kwepombi, uye koni yekunze ye sleeve yakavharwa zvakasimba nekoni ye. majoini muviri pasi pekumanikidzwa, saka inogona nekuvimbika kudzivirira kuvuza. Zvakaita seinstrumentation mavharuvhu.Zvakanakira iyi fomu yekubatanidza ndezvi:
(1) Duku vhoriyamu, huremu huremu, chimiro chakareruka, nyore disassembly uye kusangana;
(2) relay yakasimba, kushandiswa kwakasiyana-siyana, inogona kutsungirira kumanikidzwa kukuru (1000 kg/square centimeter), tembiricha yepamusoro (650 ℃) uye kuzununguka;
(3) inogona kusarudza zvinhu zvakasiyana-siyana, zvakakodzera kudzivirira ngura;
(4) kurongeka kwekugadzira hakuna kukwirira;
(5) nyore kuisa pakakwirira.
5. Clamp connection
Iyo inokurumidza nzira yekubatanidza inoda mabhoti maviri chete uye inokodzera mavharuvhu akaderera anowanzo kubviswa.
