RF - Nkhope Yokwezeka

Flange yokwezeka ya nkhope ndi mtundu wofala kwambiri womwe umagwiritsidwa ntchito popanga mbewu, ndipo umadziwika mosavuta. Amatchulidwa ngati nkhope yokwezeka chifukwa mawonekedwe a gasket amakwezedwa pamwamba pa nkhope yozungulira yozungulira. Mtundu wa nkhope uwu umalola kugwiritsa ntchito mitundu yambiri ya mapangidwe a gasket, kuphatikizapo mitundu ya mapepala a mphete athyathyathya ndi zida zachitsulo monga chilonda chozungulira ndi mitundu iwiri ya jekete.

Cholinga cha RF flange ndikuyika kupanikizika kwambiri pagawo laling'ono la gasket ndikuwonjezera mphamvu yolumikizirana. Diameter ndi kutalika zili mu ASME B16.5 yofotokozedwa, ndi gulu lamphamvu ndi m'mimba mwake. Kupanikizika kwa flange kumatsimikizira kutalika kwa nkhope yokwezeka.

Kumaliza kwa nkhope ya flange kwa ASME B16.5 RF flanges ndi 125 mpaka 250 µin Ra (3 mpaka 6 µm Ra).

M - Male Face

FM- Nkhope Yachikazi

Ndi mtundu uwu, ma flanges ayeneranso kufananizidwa. Nkhope imodzi ya flange ili ndi malo omwe amapitilira nkhope ya flange (Male). Flange ina kapena mating flange ali ndi vuto lofananira (Wamkazi) lopangidwa ndi nkhope yake.
Nkhope yachikazi ndi 3/16-inch kuya, nkhope yamphongo ndi 1/4-inchi mmwamba, ndipo zonse zimakhala zosalala. Mbali yakunja ya nkhope ya mkazi imagwira ntchito kuti ipeze ndikusunga gasket. Mu mfundo 2 Mabaibulo zilipo; Ma Flange Aang'ono a M&F ndi Ma Flange Aakulu a M&F. Maonekedwe achimuna ndi aakazi omwe amakumana nawo nthawi zambiri amapezeka pa chipolopolo cha Heat Exchanger kupita kumayendedwe ndi kuphimba ma flanges.

T - Lirime Nkhope

G-Groove Face

Nkhope za Lilime ndi Groove za flanges ziyenera kufananizidwa. Nkhope imodzi ya flange ili ndi mphete yokwezeka (Lilime) yomangidwira kumaso kwa flange pomwe mating flange amakhala ndi kupsinjika kofananira (Groove) kumaso kwake.

Maonekedwe a lilime-ndi-groove amakhala okhazikika m'magulu akulu ndi ang'onoang'ono. Iwo amasiyana mwamuna ndi mkazi kuti diameters mkati mwa lilime-ndi-poyambira musati kupitirira mu flange m'munsi, motero kusunga gasket pa m'mimba mwake mkati ndi kunja. Izi zimapezeka kawirikawiri pazivundikiro za pampu ndi Maboneti a Vavu.

Kulumikizana kwa lilime-ndi-groove kulinso ndi ubwino chifukwa kumadzigwirizanitsa ndipo kumakhala ngati nkhokwe ya zomatira. Cholowa cha scarf chimasunga mzere wolozera kuti ugwirizane ndi cholumikizira ndipo sichifuna ntchito yayikulu yopangira makina.

Nkhope zonse za flange monga RTJ, TandG ndi FandM sizidzalumikizidwa palimodzi. Chifukwa cha izi ndikuti mawonekedwe olumikizana samagwirizana ndipo palibe gasket yomwe ili ndi mtundu umodzi mbali imodzi ndi mtundu wina mbali inayo.

RTJ(RJ) -Nkhope Yophatikiza Mtundu Wa mphete

Mitundu Yophatikiza Yophatikiza Flanges nthawi zambiri imagwiritsidwa ntchito pazovuta kwambiri (Makalasi 600 ndi apamwamba) komanso / kapena ntchito zotentha kwambiri kuposa 800 ° F (427 ° C). Amakhala ndi ma grooves odulidwa kumaso awo omwe amawombera zitsulo. The flanges chisindikizo pamene omangika mabawuti compress ndi gasket pakati flanges mu grooves, deforming (kapena Coining) ndi gasket kuti kukhudzana wapamtima mkati grooves, kupanga zitsulo zitsulo chisindikizo.

Flange ya RTJ ikhoza kukhala ndi nkhope yokwezeka yokhala ndi ring groove yomwe imayikidwamo. Nkhope yokwezeka iyi simagwira ntchito ngati gawo lililonse la njira zosindikizira. Kwa ma flange a RTJ omwe amasindikizidwa ndi ma ring gaskets, nkhope zokwezeka za ma flange olumikizidwa ndi olimba amatha kulumikizana. Pankhaniyi, gasket wothinikizidwa sadzakhala ndi katundu wowonjezera kupyola nyonga bawuti, kugwedera ndi kuyenda sangathe kupitirira kuphwanya gasket ndi kuchepetsa kulumikiza kukangana.
