Kodi mumadziwa bwanji za flanges akhungu?

Ma flange akhungu ndi zinthu zofunika kwambiri pamapaipi omwe amagwiritsidwa ntchito kusindikiza kumapeto kwa chitoliro, valavu, kapena kutsegulira kwa chotengera chokakamiza.Blind flanges ndi ma discs ngati mbale omwe alibe pakati, kuwapangitsa kukhala abwino kutseka mapeto a mapaipi.mawonekedwe akhungumu ntchito ndi mawonekedwe.

Chiyambi cha Zamalonda

Ma flange akhungu amapangidwa kuchokera kuzinthu zosiyanasiyana, kutengera zofunikira zomwe zimagwiritsidwa ntchito.Zida monga chitsulo chosapanga dzimbiri, chitsulo cha carbon, ndi alloy zitsulo zimagwiritsidwa ntchito kwambiri.Ma flanges amapangidwa kuti agwirizane ndi mapaipi okhala ndi zovuta zosiyanasiyana, makulidwe, ndi kutentha.Pali mitundu yosiyanasiyana ya ma flanges akhungu, kuphatikiza ma flanges akhungu okweza, ma ring type joint (RTJ) blind flanges, ndi ma flange akhungu a nkhope.Kusankha kwa blind flange kuti mugwiritse ntchito kumatengera zosowa za pulogalamuyo.

Mafotokozedwe ndi Ma Model

Ma flange akhungu amabwera mosiyanasiyana ndi mitundu yosiyanasiyana, iliyonse yopangidwa kuti ikwaniritse zofunikira zapadera.Amapezeka mosiyanasiyana, kuyambira 1/2 "mpaka 48" akhungu otukuka amaso ndi 1/2" mpaka 24" a RTJ.akhungu flanges.Makulidwe a flange amasiyanasiyana, nawonso, ndi makulidwe oyenera kuyambira 1/4 "mpaka 1", pomwe makulidwe a chitoliro chakhungu cholemera chimachokera ku 2 "-24".Mitundu ya flange imabwera mu Class 150 mpaka Class 2500, PN6 mpaka PN64 pressure rating, ndi ASME/ANSI B16.5, ASME/ANSI B16.47, API, ndi MSS SP44 miyezo.

Ntchito ndi magulu

Kuyang'ana mawonekedwe, mbale yakhungu nthawi zambiri imagawika m'mbale yamtundu wamba, mbale yakhungu, mbale ya pulagi ndi mphete zoyambira (mbale yamapulagi ndi mphete zochizira ndizosawonana).Chipinda chakhungu chimagwiranso ntchito yodzipatula komanso kudula ngati mutu, kapu ya chitoliro ndi pulagi yowotcherera.Chifukwa cha ntchito yake yabwino yosindikiza, nthawi zambiri imagwiritsidwa ntchito ngati njira yodalirika yodzipatula pamakina omwe amafunikira kudzipatula kwathunthu.Mbalame-mtundu lathyathyathya akhungu mbale ndi bwalo olimba ndi chogwirira, amene ntchito dongosolo mu kudzipatula pamikhalidwe yachibadwa.Wakhungu wowonera amapangidwa ngati wakhungu wowonera.Mapeto amodzi ndi mbale yakhungu ndipo mapeto ena ndi mphete yogwedeza, koma m'mimba mwake ndi yofanana ndi m'mimba mwake ya chitoliro ndipo sichigwira ntchito.Chovala chakhungu chowonera ndichosavuta kugwiritsa ntchito.Pamene kudzipatula pakufunika, ntchito akhungu mbale mapeto.Pamene ntchito bwinobwino chofunika, ntchito throttling mphete mapeto.Itha kugwiritsidwanso ntchito kudzaza kusiyana kwa mbale yakhungu papaipi.Chinthu china ndi chizindikiritso chodziwikiratu komanso chosavuta kuzindikira malo oyika

Kuyerekeza ndi Zogulitsa Zofanana

Ma flange akhungu ndi njira yabwino yosindikizira kuposa zinthu zina zosindikizira.Ndiwolimba komanso olimba kuposa ma gaskets, omwe amatha kutha pakapita nthawi.Ma flange akhungu amakhalanso odalirika kuposa ma flanges omangika, omwe amafunikira kumangitsa ndikuwongoleranso kuti asatayike.Flanges akhungu amapereka chisindikizo chokhazikika ndipo amafuna kusamalidwa pang'ono, kuwapanga kukhala njira yotsika mtengo pakapita nthawi.

Pomaliza, ma flange akhungu ndi zinthu zofunika kwambiri pamapaipi, zomwe zimagwiritsidwa ntchito kusindikiza kumapeto kwa chitoliro kapena kutsegulira kwa valve.Amapangidwa kuchokera kuzinthu zosiyanasiyana ndipo amabwera mosiyanasiyana, makulidwe, ndi zitsanzo, kuwapanga kukhala oyenera ntchito zosiyanasiyana.Ma flanges ndi odalirika, okhazikika, ndipo amafuna kusamalidwa pang'ono, zomwe zimawapangitsa kukhala otsika mtengo pakapita nthawi.Ma flange akhungu ndi njira yabwino yosindikizira kuposa ma gaskets ndi ma bolts a thupi ndipo amapereka chisindikizo chokhazikika kuti asatayike.Ngati mukufuna wodalirika komanso wodalirika wosawona flange, tiganizireni.Tili ndi mitundu ingapo ya ma flanges akhungu omwe amakwaniritsa miyezo yapamwamba kwambiri, kuwonetsetsa kuti makina anu opopera ali otetezeka komanso odalirika.
