FLANGE NHUNGAMIDZO

Zvinotaurwa Nezvemuviri
Chokutanga uye chakakosha, flange inofanira kukodzera pombi kana midziyo iyo yakagadzirirwa.Mamiriro emuviri wepombi flanges anosanganisira zviyero uye magadzirirwo maumbirwo.

Flange Dimensions
Zviyero zvemuviri zvinofanirwa kutsanangurwa kuitira saizi flange nemazvo.

Kunze kwedhayamita (OD) chinhambwe chiri pakati pemativi maviri anopokana echiso cheflange.
Hukobvu (hukobvu) zvinoreva kukora kwerimu rekunze rinosungirirwa, uye hakusanganisi chikamu cheflange chinobata pombi.
Bolt denderedzwa dhayamita kureba kubva pakati pegomba rebhaudhi kusvika pakati pegomba rinopikisa.
Saizi yepombi imhando yepombi flange inoenderana saizi yepombi, kazhinji inogadzirwa zvinoenderana nezviyero zvinogamuchirwa.Kazhinji inotsanangurwa nenhamba mbiri dzisiri-dimensional, saizi yepombi yezita (NPS) uye chirongwa (SCH).
Nominal bore size ndiyo dhayamita yemukati yeflange yekubatanidza.Paunenge uchigadzira uye kurongeka chero ipi zvayo yepombi yekubatanidza, zvakakosha kuenzanisa chiyero chebhore chechidimbu nekukura kwebhomba yekubatanidza pombi.
Flange Faces
Zviso zveFlange zvinogona kugadzirwa kune nhamba huru yezvimiro zvetsika zvichienderana nedhizaini zvinodiwa.Mimwe mienzaniso inosanganisira:

Flat
Chiso chakasimudzwa (RF)
Mhete yemhando yekubatanidza (RTJ)
O-ring groove
Mhando dzePipe Flanges
Pipe flanges inogona kukamurwa kuva mhando sere zvichienderana nekugadzira.Mhando idzi ibofu, lap joint, orifice, kuderedza, kutsvedza, socket-weld, threaded, uye weld neck.

Blind flanges ma plates eraundi asina kana centre anobatirira anoshandiswa kuvhara panoperera pombi, mavharuvhu, kana midziyo.Vanobatsira mukubvumira kupinda nyore kumutsara kana uchinge wavharwa.Iwo anogona zvakare kushandiswa kuyerera kumanikidza kuyedzwa.Mabofu maflange anogadzirwa kuti akwane mapaipi akajairwa muhukuru hwese pachiyero chepamusoro chekumanikidza kupfuura mamwe marudzi eflange.

Lap joint flanges dzinoshandiswa papombi dzakaiswa pombi yakavharwa kana kuti ine pamakumbo pajoinhi stub.Vanogona kutenderera vachitenderedza pombi kuti vabvumire kurongeka kuri nyore uye kuungana kwemaburi emabhoti kunyangwe mawelds apera.Nekuda kweiyo bhenefiti, lap joint flanges inoshandiswa mumasisitimu anoda kazhinji disassembly yeflanges uye pombi.Iwo akafanana neanotsvedza-pamaflange, asi ane radius yakakomberedzwa pabore uye kumeso kuti agadzike pamakumbo akabatana stub kupera.Maredhiyo ekumanikidzwa kwemakumbo ejoint flanges akadzikira, asi akakwirira pane anotsvedza-pamaflange.

Slip-on flanges akagadzirirwa kutsvedza pamusoro pemagumo epombi uye obva aiswa weld panzvimbo.Ivo vanopa nyore uye yakaderera-mutengo kuisirwa uye yakanakira yakaderera kumanikidza maapplication.

Socket weld flanges yakanakira diki-saizi, yakakwirira-kudzvanywa pombi.Kugadzirwa kwavo kwakafanana neyekutsvedza-pane flanges, asi mukati mehomwe dhizaini inobvumira kubereka kwakatsetseka uye kuyerera kwemvura kuri nani.Kana nemukati welded, flanges aya zvakare kuneta simba simba 50% mukuru pane kaviri welded slip-on flanges.

Threaded flanges akakosha marudzi epombi flange anogona kusungirirwa papombi pasina welding.Iwo akarukwa mubore kuti aenderane neshinda yekunze papombi uye anonamirwa kugadzira chisimbiso pakati peflange nepombi.Seal welds inogona zvakare kushandiswa pamwe chete neshinda yekubatanidza kune yakawedzera kusimbiswa uye chisimbiso.Iyo inonyanya kushandiswa kune madiki mapaipi uye yakaderera kudzvinyirira, uye inofanira kudziviswa mumashandisirwo ane mitoro mikuru uye torque yakakwirira.

Welding neck flanges ine refu tapered hub uye inoshandiswa kune yakanyanya kudzvanywa application.Iyo tapered hub inotamisa kushushikana kubva kune flange kuenda kune pombi pachayo uye inopa simba rekusimbisa iro rinopesana nedhishi.
