Kusiyana Pakati pa FF Flange ndi RF Flange Kusindikiza Pamwamba

Pali mitundu isanu ndi iwiri ya malo osindikizira a flange: nkhope yonse FF, nkhope yokwezeka ya RF, nkhope yokwezeka M, nkhope ya concave FM, nkhope ya tenon T, nkhope ya G, ndi nkhope ya mphete ya RJ.

Pakati pawo, ndege zonse za FF ndi convex RF zimagwiritsidwa ntchito kwambiri, motero zimayambitsidwa ndikusiyanitsidwa mwatsatanetsatane.

FF nkhope yonse

Kutalika kwa mawonekedwe a Flange Flange (FF) ndikofanana ndi mzere wolumikizira bawuti waflange. Gasket ya nkhope yonse, nthawi zambiri yofewa, imagwiritsidwa ntchito pakati pa awiriflat flanges.

Malo osindikizira a nkhope yathyathyathya ndi athyathyathya kwathunthu, omwe ndi oyenera nthawi zocheperako komanso sing'anga yopanda poizoni.

RF adakweza nkhope

Ma flange amaso okwera (RF) amadziwika mosavuta chifukwa malo a gasket ali pamwamba pa mzere wopindika wa flange.

Malo osindikizira amtundu wokwezeka ndi omwe amagwiritsidwa ntchito kwambiri pakati pa mitundu isanu ndi iwiri. Miyezo yapadziko lonse lapansi, machitidwe aku Europe ndi miyezo yapakhomo zonse zili ndi kutalika kokhazikika. Komabe, mu

American standard flanges, tisaiwale kuti kutalika kwa kuthamanga kwambiri kumawonjezera kutalika kwa kusindikiza pamwamba. Palinso mitundu yambiri ya gaskets.

Ma gaskets a RF okwera kumaso osindikizira ma flanges amaphatikizirapo ma gaskets osiyanasiyana osapangidwa ndi zitsulo komanso ma gaskets okutidwa; Metal wokutidwa gasket, ozungulira bala gasket (kuphatikiza mphete yakunja kapena yamkati

mphete), etc.

Kusiyana

Kupanikizika kwaFF nkhope yonse ya flangenthawi zambiri imakhala yaying'ono, yosapitilira PN1.6MPa. Malo olumikizirana osindikizira a FF full face flange ndi yayikulu kwambiri, ndipo pali magawo ambiri kupitilira muyeso wa

ogwira kusindikiza pamwamba. Ndizosapeŵeka kuti malo osindikizira sangagwirizane bwino, kotero kusindikiza sikuli bwino. Malo olumikizirana ndi mawonekedwe osindikizira a flange ndi ochepa, koma

zimangogwira ntchito mkati mwa malo osindikizira ogwira mtima, chifukwa kusindikiza kumakhala bwino kusiyana ndi mawonekedwe a nkhope yonse.
