Zogulitsa Zambiri

Chiyambi cha Zamalonda

AWWA C207 ndi muyezo wa flanges zitsulo ndi akhungu flanges woperekedwa ndi American Water Works Association (AWWA).Muyezowu umatchula zofunikira pakukula, zinthu, kukakamiza, m'mimba mwake mwadzina, ndi mawonekedwe a flange azitsulo zachitsulo ndi mbale zakhungu.
AWWA C207 si muyezo wapadziko lonse lapansi, koma mulingo wadziko la America (ANSI/AWWA C207).Komabe, mayiko ambiri ndi zigawo atengera muyezo wa AWWA C207 kapena mitundu yake ngati mulingo wawo wamba wazitsulo zachitsulo ndi ma flange akhungu.Mwachitsanzo, Canada, Australia, New Zealand, Mexico, ndi mayiko ena a Middle East amagwiritsa ntchito muyezo wa AWWA C207 kapena mitundu yake.

Theflat kuwotcherera flange ndi khosimuyeso wa AWWA C207 ndi kugwirizana kwa chitsulo cha flange, komwe kumatchedwanso mphete ya flange, yomwe ili ndi nkhope yozungulira ndi khosi la cylindrical.Mtundu uwu wa flange nthawi zambiri umagwiritsidwa ntchito kulumikiza mapaipi, mavavu, mapampu, ndi zida zina zama hydraulic system, mapaipi amadzi, ndi njira zina zotumizira madzi.

Kukula ndi kukakamizidwa:
Malinga ndi muyezo wa AWWA C207, kuchuluka kwa ma flanges a khosi lathyathyathya kumayambira mainchesi 3 mpaka 144 mainchesi, ndipo kupanikizika kumayambira pa 150 pounds pa sikweya inchi kufika pa 2500 pounds pa lalikulu inchi.Magawo monga makulidwe a khosi ndi makulidwe, makulidwe a nkhope ya flange, kuchuluka ndi mainchesi a mabowo a bawuti, ndi mtundu ndi makulidwe a ma gaskets osindikizira a ma flanges owotcherera okhala ndi makosi amafotokozedwanso mu muyezo.
Koma pakupanga kwenikweni, chifukwa cha zovuta za zida ndi zoletsa zotumizira kunja, kukula kwenikweni komwe kumakhala pafupifupi mainchesi 3 mpaka 72, yomwe ndi DN100 mpaka DN1800.

Kuyika:
Kuyika kwakutsika pa flangenthawi zambiri pamafunika kulumikiza pamwamba pa flange ndi mabawuti ndi mtedza kumapeto kwa payipi, ndi kusindikiza ndi ma gaskets kuti zitsimikizire kuti mipope yothina ndi yothina ndi madzi.Njira yolumikizira iyi ili ndi maubwino olumikizana bwino, kudalirika kwakukulu, ndi kuphatikizika kolimba, ndipo imagwiritsidwa ntchito kwambiri pamapaipi osiyanasiyana.

Kuyerekezera

Khosi lathyathyathya kuwotcherera flange ndi mbale lathyathyathya kuwotcherera flange ndi awiri ntchito zitsulo flange zolumikizira, amene alizosiyana pang'ono pamapangidwe ndi kagwiritsidwe ntchito.Zotsatirazi ndi kufananiza pakati pawo:

Chikhalidwe mawonekedwe: The khosi lathyathyathya kuwotcherera flange ndi khosi cylindrical, pamene mbale mtundu lathyathyathya kuwotcherera flange alibe khosi ndipo zimangokhala ndi flange lathyathyathya ndi flange gasket.

Kuchuluka kwa ntchito: khosi lathyathyathya kuwotcherera flanges nthawi zambiri ntchito kulumikiza mapaipi, mavavu, mapampu, ndi zipangizo zina mu makina hayidiroliki, mapaipi madzi, ndi machitidwe madzi kutengerapo, pamene mbale mtundu lathyathyathya kuwotcherera flanges nthawi zambiri ntchito kulumikiza mapaipi ang'onoang'ono ndi zipangizo. .

Kuponderezana: Chifukwa cha kukhuthala kwa khosi ndi flange pamwamba pa khosi lathyathyathya kuwotcherera flange, nthawi zambiri imatha kupirira milingo yayikulu yoyambira pa mapaundi 150 pa mainchesi lalikulu mpaka mapaundi 2500 pa inchi imodzi.Mitundu ya mbale zowotcherera zosalala zimatha kupirira kupanikizika kocheperako, ndi kupanikizika kosiyanasiyana komwe kumakhala pansi pa mapaundi 150 pa inchi imodzi.

Njira yoyika: Zowotcherera zokhotakhota zokhotakhota nthawi zambiri zimafunikira kugwiritsa ntchito mabawuti ndi mtedza kuti zilumikizidwe kumapeto kwa payipi, pomwe ma flanges amtundu wamtundu wathyathyathya nthawi zambiri amagwiritsa ntchito ma gaskets ndi mabawuti kuti alumikizane kumapeto kwa payipi.Njira zonse zolumikizira zimafunikira kuwongolera kolimba kwa torque yolumikizira komanso kulimba.

Mwachidule, khosi lathyathyathya kuwotcherera flanges ndi mbale lathyathyathya kuwotcherera flanges ndi ntchito zosiyanasiyana mu machitidwe osiyana mapaipi ndi zipangizo.Kusankhidwa kwa zolumikizira zoyenera za flange kuyenera kutsimikiziridwa malinga ndi zofunikira za dongosolo la mapaipi ndi zida.
