Flange Faces

Chii chinonzi Flange face?

Mhando dzakasiyana dzezviso zveflange dzinoshandiswa senzvimbo dzekubatanidza kugadzika chisimbiso gasket zvinhu. ASME B16.5 uye B16.47 inotsanangura marudzi akasiyana-siyana eflange yakatarisana, kusanganisira iyo yakasimudzwa chiso, iyo huru yemurume neyechikadzi yakatarisana iyo ine chiyero chakafanana kupa nzvimbo yakakura yekuonana.

Mamwe maflange anotarisana akafukidzwa nezviyero izvi anosanganisira hombe uye diki rurimi-uye-groove yakatarisana, uye mhete yekubatanidza yakatarisana yakanangana nemhete yemhando yesimbi gaskets.

Chiso chakasimudzwa (RF)

Iyo Yakasimudzwa Face flange ndiyo inonyanya kushandiswa mhando mu process plant applications, uye iri nyore kuziva. Inotumidzwa sechiso chakasimudzwa nekuti nzvimbo dzegasket dzinosimudzwa pamusoro pechiso chedenderedzwa. Rudzi rwechiso urwu runobvumira kushandiswa kwemusanganiswa wakafara wegasket dhizaini, kusanganisira flat ring sheet sheet marudzi uye esimbi composites senge spiral ronda uye kaviri jekete mhando.

Chinangwa cheRF flange ndechekutarisa zvakanyanya kudzvanywa pane diki gasket nzvimbo uye nekudaro kuwedzera kudzvanywa kwekugona kwejoint. Diameter uye urefu zviri muASME B16.5 inotsanangurwa, nekirasi yekumanikidza uye dhayamita. Chiyero chekumanikidza cheflange chinotarisa kureba kwechiso chakasimudzwa.

Iyo yakajairika flange kumeso kupera kweASME B16.5 RF flanges ndeye 125 kusvika 250 µin Ra (3 kusvika 6 µm Ra).

Yakasimudzwa Face urefu

Kune hurefu huyero H uye B yeese akatsanangurwa zviyero zveflange pane ino webhusaiti, kunze kweLap Joint flange, zvakakosha kuti unzwisise uye uyeuke zvinotevera:

Mumakirasi ekumanikidza 150 uye 300, kureba kwechiso chakasimudzwa chingangoita 1.6 mm (1/16 inch). Mumakirasi maviri aya ekumanikidza, vangangove vese vatengesi veflange, vanoratidza mukhathalogi yavo kana bhurocha, iyo H uye B dimensions kusanganisira iyo yakasimudzwa kureba kwechiso. ((Mufananidzo 1))

Mumakirasi ekumanikidza 400, 600, 900, 1500 uye 2500, kureba kwechiso chakasimudzwa kunosvika 6.4 mm (1/4 inch). Mune aya makirasi ekumanikidza, vatengesi vazhinji vanoratidza H uye B zviyero kusasanganisa kureba kwechiso. (Mufananidzo 2)

Chiso chakafuratira (FF)

Iyo Flat Face flange ine gasket pamusoro mundege imwechete seyakatarisana nedenderedzwa rebholting. Zvishandiso zvinoshandisa flat face flanges kazhinji ndeizvo izvo mating flange kana flanged fitting inogadzirwa kubva pakukandira.

Flat face flanges haimbofa yakasungirirwa kune yakasimudzwa face flange. ASME B31.1 inotaura kuti kana uchibatanidza flat face cast cast iron flanges kune carbon steel flanges, chiso chakasimudzwa pa carbon steel flange chinofanira kubviswa, uye kuti chiso chakazara gasket chinodiwa. Izvi ndezvekuchengetedza simbi yakatetepa, diki diki simbi inokanda simbi kuti isatukire mumukana wakakonzerwa nechiso chakasimudzwa checarbon steel flange.

Ring-Type Joint (RTJ)

Iyo Ring Type Joint flanges inowanzo shandiswa mukumanikidza kwakanyanya (Kirasi 600 uye yepamusoro mwero) uye/kana yakakwirira tembiricha masevhisi pamusoro pe800°F (427°C). Vane grooves akachekwa zviso zvavo izvo simbi mhete gaskets. The flanges chisimbiso kana wakaomeswa mabhaudhi compress the gasket pakati flanges kupinda grooves, deforming (kana Coining) ari gasket kuita hwepedyo kuonana mukati grooves, kugadzira simbi kuti simbi chisimbiso.

Iyo RTJ flange inogona kunge iine chiso chakasimudzwa chine ring groove yakagadzirwa mairi. Ichi chiso chakasimudzwa hachishandi sechinhu chero chipi zvacho chekuisa chisimbiso. Kune RTJ flanges inonamira nemhete gaskets, zviso zvakasimudzwa zveakabatana uye akasimbiswa flanges anogona kusangana. Muchiitiko ichi iyo gasket yakamanikidzwa haizotakure imwe mutoro kupfuura bhaudhi tension, vibration uye kufamba hakugone kupfuurira kupwanya gasket uye kuderedza kushushikana kwekubatanidza.

Mhete Type Joint gaskets

Mhete Type Joint gaskets isimbi yekuisa chisimbiso mhete, yakakodzera kune yakakwirira-kudzvanywa uye yakakwirira-tembiricha application. Iwo anogara achiiswa kune akakosha, anoperekedza flanges ayo anovimbisa yakanaka, yakavimbika chisimbiso nesarudzo chaiyo yemaprofile uye zvinhu.

Mhete Type Joint gaskets akagadzirirwa kuvhara ne "yekutanga mutsara kusangana" kana wedging chiitiko pakati pemating flange uye gasket. Nekushandisa kudzvanywa pachisimbiso chekubatanidza kuburikidza nebhaudhi simba, simbi "yakapfava" yegasket inoyerera ichipinda muchimiro chemicrofine cheiyo yakaoma flange zvinhu, uye kugadzira chisimbiso chakasimba uye chinoshanda.

Ruzhinji rwemhando yakashandiswa imhandoRmhete inogadzirwa zvinoenderana neASME B16.20 inoshandiswa neASME B16.5 flanges, kirasi 150 kusvika 2500. Majoini emhando yemhando ye "R" anogadzirwa mune zvese oval uye octagonal configurations.

TheOctagonalmhete ine chisimbiso chepamusoro chekuvhara kupfuura ovha uye ingave iyo yakasarudzika gasket. Nekudaro, iyo chete oval cross chikamu inogona kushandiswa mune yekare mhando kutenderera kuzasi groove. Iyo nyowani nyowani yakadzika pasi groove dhizaini inogashira ingave ovha kana octagonal muchinjiko chikamu.

Chimiro R mhete yemhando yejoini dzakagadzirwa kuti iname kudzvanywa kusvika pa6,250 psi zvinoenderana neASME B16.5 pressure ratings uye kusvika 5,000 psi.

Vanoisa chisimbiso nekutanga mutsara kusangana kana chiitiko chemuchato sezvo masimba ekumanikidza anoshandiswa. Kuomarara kwemhete kunofanirwa kugara kuri kushoma pane kuoma kweflanges.

Kusarudzwa kwezvinhu

Tafura iri pazasi inoratidza zvinhu zvinonyanya kushandiswa zvemhando yemhete majoini.

Tongue-and-Groove (T&G)

Iyo Tongue neGroove zviso zveiyi flanges zvinofanirwa kufananidzwa. Chiso chimwe cheflange chine mhete yakasimudzwa (Rurimi) yakashongedzerwa pachiso cheflange uku iyo yekubatanidza flange ine dhizaini inoenderana (Groove) yakagadzirwa kumeso kwayo.

Tongue-and-groove faces inogadziriswa mumhando mbiri huru nediki. Vanosiyana kubva kumurume-ne-mukadzi pakuti mukati madhayamita erurimi-uye-groove haapfuuri muchikamu cheflange, nokudaro kuchengetedza gasket pairi mukati uye kunze kwedhayamita. Izvi zvinowanzowanikwa pamavhavha epombi uye Mabhoneti eValve.

Rurimi-ne-groove majoini anewo bhenefiti pakuti anozvigadzirisa uye anoita sechigadziro chekunamira. Iyo scarf joint inochengeta axis yekurodha inoenderana nejoinhi uye haidi yakakura machining oparesheni.

General flange zviso zvakaita seRTJ, TandG neFandM hazvimbofa zvakasungwa pamwechete. Chikonzero cheizvi ndechekuti nzvimbo dzekusangana hadzienderane uye hapana gasket ine imwe mhando kune rumwe rutivi uye rumwe rudzi kune rumwe rutivi.

Murume-ne-Mukadzi (M&F)

Nemhando iyi maflange zvakare anofanira kufananidzwa. Chiso chimwe cheflange chine nzvimbo inotambanukira kupfuura yakajairika flange kumeso (Murume). Imwe flange kana mating flange ane dhiri rinoenderana (Mukadzi) rakagadzirwa kumeso kwayo.

Chiso chemukadzi chakadzika 3/16-inch, chiso chechirume chakareba 1/4-inch, uye ese ari maviri akatsetseka apera. Iyo yekunze dhayamita yechiso chemukadzi inoita kutsvaga nekuchengetedza gasket. In musimboti 2 shanduro dziripo; iyo Diki M&F Flanges uye Makuru M&F Flanges. Tsika dzechirume nedzechikadzi dzinotarisana dzinowanzo kuwanikwa paHeat Exchanger shell kugero uye kuvhara flanges.
