Mukayika ndikugwiritsa ntchito akhungu flange, muyenera kulabadira mfundo ziwirizi.

Flanges ndi zida zapaipi zomwe zimagwiritsidwa ntchito nthawi zambiri kulumikiza mapaipi ndi mapaipi kapena kulumikiza zida ziwiri mumayendedwe a mapaipi.Pali mitundu yambiri yaflanges,mongama flanges opangidwa ndi ulusi, kuwotcherera khosi flanges, mbale kuwotcherera flanges, etc. (pamodzi amatchedwa flanges).Komabe, m'moyo weniweni, mutha kuwonanso kuti pali chinthu china cha flange chotchedwa blind flange.Kodi pali kusiyana kotani pakati pa common flange ndi blind flange?Kodi kukhazikitsa ndi kugwiritsa ntchito akhungu flange?

1. Kusiyana pakati pa flange ndi blind flange

(1) Pa fulange pali mabowo.Panthawi yolumikizana, ma flanges awiriwa amafunika kumangirizidwa ndi ma bolts.Flange imasindikizidwa ndi ma gaskets kuti igwire ntchito yosindikiza, kapena kutengapo gawo kwakanthawi pakuyesa;
The akhungu flange wapangidwa kuponyera kapena ulusi kugwirizana kapena kuwotcherera.Ndi flange yopanda mabowo pakati.Amagwiritsidwa ntchito makamaka kuti asindikize kutsogolo kwa chitoliro, ndi kusindikiza chitoliro cha chitoliro.Ntchito yake ndi yofanana ndi mutu ndi chivundikiro cha chitoliro, ndipo imagwira ntchito yodzipatula kugwedezeka ndi kudula.Komabe, akhungu flange chisindikizo ndi zochotseka kusindikiza chipangizo.Chisindikizo cha mutu sichinakonzekere kutsegulidwanso.Flange yakhungu imatha kuchotsedwa kuti ithandizire kugwiritsidwanso ntchito kwa chitoliro m'tsogolomu.

(2) Chifukwa flange ili ndi makhalidwe abwino, nthawi zambiri imagwiritsidwa ntchito popanga mankhwala, zomangamanga, mafuta, ukhondo, mapaipi, kuteteza moto ndi ntchito zina zofunika;
M'pofunika kukhazikitsa mbale akhungu pa kugwirizana kwa zida ndi payipi, makamaka pa malire m'dera kunja kwa malire dera kumene zosiyanasiyana ndondomeko zinthu mipope zikugwirizana.Komabe, poyesa mphamvu ya mapaipi kapena kuyesa kusindikiza, sikuloledwa kugwiritsa ntchito mbale zakhungu nthawi imodzi ndi zida zolumikizira (monga turbine, kompresa, gasifier, reactor, etc.) poyambira kukonzekera koyambira.

Koma kwenikweni, pali zofanana zambiri pakati pa flanges ndi flange blind plates.Mwachitsanzo, pali mitundu yambiri ya malo osindikizira, monga ndege, convex, concave ndi convex, tenon ndi groove, ndi malo ogwirizanitsa mphete;Amagwiritsidwa ntchito polumikizana ndi flange, yokhala ndi ma flanges, gasket ndi ma bolts angapo ndi mtedza.Gasket imayikidwa pakati pa malo awiri osindikizira a flange.Pambuyo kumangitsa nati, kupanikizika kwapadera pa gasket pamwamba kumafika pamtengo wina, zomwe zingayambitse mapindikidwe, ndipo magawo osagwirizana pa malo osindikizira adzadzazidwa kuti agwirizane.

2. Kuyika ndi kugwiritsa ntchito mbale yakhungu ya flange
Mbali yakhungu ya flange imathanso kulumikizidwa ndi flange, ndiye kuti, gasket imayikidwa pakati pazigawo ziwiri zosindikizira za flange.Mtedza utatha kumangirizidwa, kupanikizika kwapadera pamtunda wa gasket kumafika pamtengo wina, ndipo kusinthika kumachitika, ndipo malo osagwirizana pa malo osindikizira amadzazidwa, kotero kuti kugwirizana kuli kolimba.Komabe, mbale yakhungu ya flange yokhala ndi zovuta zosiyanasiyana imakhala ndi makulidwe osiyanasiyana ndipo imagwiritsa ntchito mabawuti osiyanasiyana;Pankhani ya mafuta sing'anga dongosolo, flange akhungu mbale sayenera kanasonkhezereka, koma mu nkhani ya machitidwe ena sing'anga, flange akhungu mbale adzakhala pansi otentha galvanizing mankhwala, osachepera kulemera kwa ❖ kuyanika nthaka ndi 610g/m2. , ndi ubwino wa flange wosawona mbale pambuyo galvanizing otentha adzayang'aniridwa malinga ndi muyezo dziko.

Pamwambapa pali kusiyana pakati pa flange ndi khungu lakhungu ndi kukhazikitsa ndi kugwiritsa ntchito khungu lakhungu.Ndikukhulupirira kuti ikhoza kukuthandizani kusankha ndikuyika flange moyenera ndikuchita ntchito yake yosindikiza.
