Flange (sae flange JBZQ 4187-97) inonziwo flange kana flange.Zvikamu zvinobatanidza pombi kune pombi kune mumwe nemumwe, zvakabatanidzwa kune pombi inopera.Kune maburi muflange, uye mabhoti anonyatso batanidza maflange maviri.Iyo flange yakavharwa negaskets.Zvisungo zvepombi (Flange pipe fittings) zvinoreva kuiswa kwepombi dzine maflange (flanges kana lands).Inogona kukandwa, screwed kana welded.
Flange yekubatanidza (flange, yakabatana) inosanganisira peya yeflanges, gasket uye akati wandei mabhaudhi uye nzungu.Iyo gasket inoiswa pakati pekuisa chisimbiso pamusoro pemaflange maviri.Mushure mekunge nati yakasimbiswa, iyo chaiyo yekumanikidza pamusoro peiyo gasket inosvika kune imwe kukosha uye yobva yakanganisa, uye inozadza kusaenzana pamusoro pechisimbiso chepamusoro kuita kuti kubatana kusimbise.Kubatana kweFlange ndiko kubatanidza kunobviswa.Zvinoenderana nezvikamu zvakabatana, inogona kukamurwa kuita mudziyo flange uye pombi flange.Zvinoenderana nerudzi rwechimiro, kune akabatanidzwa flange, loop flange uye yakaomeswa flange.Akajairika akakosha maflange anosanganisira flat welding flanges uye butt welding flanges.Flat welding flanges haina kusimba uye inokodzera nguva apo kudzvanywa p≤4MPa.butt welding flanges, inozivikanwawo seyepamusoro mitsipa flanges, ine yakakwirira kuomarara uye yakakodzera kune dzimwe nguva nekumanikidza kwakanyanya uye tembiricha.
Kune marudzi matatu eflange yekuisa chisimbiso pamusoro: flat sealing surface, yakakodzera nguva dzine low pressure uye isiri-chepfu yepakati.concave-convex yekuisa chisimbiso pamusoro, inokodzera nguva dzinenge dzanyanya kudzvanywa, midhiya ine muchetura uye nguva dzekumanikidza.Iyo gasket mhete yakagadzirwa nechinhu chinogona kuburitsa plastiki deformation uye ine rimwe simba.Mazhinji emagaskets anochekwa kubva kune asiri-simbi mahwendefa, kana kugadzirwa nehunyanzvi mafekitori zvichienderana nehukuru hwakatarwa.Zvinhu zvacho mahwendefa erabha easbestos, mahwendefa easbestosi, mahwendefa epolyethylene, nezvimwewo.Kune zvakare simbi-yakavharwa gasket yakagadzirwa neyakaputirwa isiri-simbi zvinhu.kune zvakare ronda gasket rakagadzirwa nematepi simbi tambo uye asbestos mitsetse.Magasi erabha akajairika akakodzera nguva apo tembiricha yakadzikira kupfuura 120°C.asbestos rubber gaskets akakodzera nguva apo tembiricha yemhute yemvura yakadzikira kupfuura 450°C, tembiricha yeoiri yakadzikira kupfuura 350°C, uye dzvinyiriro iri pasi pe5MPa.Pakati, iyo inonyanya kushandiswa ndeye acid-resistant asbestos board.Muzvigadzirwa zvepamusoro-soro uye mapaipi, mapeji emagetsi e-lens-shaped kana mamwe-akaumbwa nemhangura, aruminiyamu, Nhamba 10 yesimbi, uye simbi isina tsvina inoshandiswa.Kubatana kwehupamhi pakati pe-high-pressure gasket uye nzvimbo yekuisa chisimbiso yakanyanya kutetepa (line contact), uye kupera kwekugadzirisa kwechisimbiso chepamusoro uye gasket inenge yakakwirira.
Flange classification: Flanges dzakakamurwa kuita threaded (wired) flanges uye welding flanges.Iyo yakaderera-kudzvanya dhayamita diki ine waya flange, uye yakakwira-kumanikidza uye yakaderera-kudzvanya madhayamita makuru anoshandisa welding flanges.Ukobvu hweplate yeflange yekumanikidza kwakasiyana uye dhayamita uye nhamba yekubatanidza mabhoti zvakasiyana.Zvinoenderana neakasiyana magiredhi ekumanikidza, maflange pads anewo akasiyana zvinhu, kubva kune yakaderera-pressure asbestos pads, high-pressure asbestos pads kusvika kusimbi pads.
1. Yakakamurwa nezvinhu kuita kabhoni simbi, simbi yakakandwa, alloy simbi, Stainless simbi, mhangura, aruminiyamu alloy, plastiki, argon, ppc, nezvimwewo.
2. Zvinoenderana nemaitiro ekugadzira, inogona kukamurwa kuita flange yefoge, cast flange, welding flange, rolled flange (oversized modhi) 3. Zvinoenderana neyakagadzirwa chiyero, inogona kukamurwa kuva yenyika standard (standard yeMinistry of Chemical). Indasitiri, petroleum standard, magetsi emagetsi chiyero) , American Standard, German Standard, Japanese Standard, Russian Standard, nezvimwe.
