Zigawo za couplings

Njira yopangira mapaipi a CNG ingagwiritsidwe ntchito kujowina mitundu yosiyanasiyana yamapaipi amitundu yosiyanasiyana. Itha kugwiritsidwa ntchito ngati makulidwe osiyanasiyana a mapaipi, zida zamapaipi ndi makulidwe a khoma. Zida zilipo kuti zipereke machitidwe okhwima kapena osinthika.

Monga momwe zilili ndi njira iliyonse yapaipi, chikhalidwe cha njirayo chiyenera kuganiziridwa popanga makina opangira mapaipi. Deta yapangidweyi imagwira ntchito makamaka ku chitoliro chakumapeto, komabe zambiri zimagwira ntchito kuzinthu zina zapaipi zomwe zimagwiritsidwa ntchito pamodzi ndi zigawo zozungulira.

Zomwe zaperekedwazo zimangotengera kapangidwe ka mapaipi pogwiritsira ntchito zinthu za CNG pazolinga zomwe akufuna. Sizinapangidwe kuti zilowe m'malo mwa akatswiri, chithandizo chaukatswiri chomwe chili chofunikira kwambiri pakugwiritsa ntchito.

Mtengo wa Rubber Gasket

Ma gaskets a CNG adapangidwa kuti azipereka moyo wadongosolo
Ntchito zosiyanasiyana.
Zida za gasket zilipo kuti zikwaniritse ntchito zambiri zamapaipi.

Zida za Rubber Gasket

Monga luso lapamwamba la elastomer, zida zapamwamba za gasket
adapezeka ndipo adawonjezedwa ku mzere wa CNG. Izi zimathandiza CNG kuti ipereke ma gaskets osiyanasiyana opangira mphira kuti apereke mwayi wosankha zinthu za CNG pazogwiritsa ntchito zosiyanasiyana.
Pakuti ambiri madzi dongosolo mapaipi ntchito, CNG kalasi EPDM mphira tikulimbikitsidwa.CNG E-kalasi mphira gasket zakuthupi ndi ntchito kwambiri mu odana ndi ukalamba ndi kutentha kukana, nkhani pa 125 C (257F) kutentha, zinthu kutentha mpweya kukalamba mayeso, thupi katundu wa zofunika unchanged.Pamene mphira mu malo sanali mpweya, monga kulimbitsa madzi dongosolo, monga kulimbitsa madzi. Kuwonongeka kwa elastomer, kutentha ndi chinthu chokhacho cholepheretsa chomwe chiyenera kuganiziridwa pozindikira kutalika kwa moyo wa elastomer mu utumiki wa madzi. Kupambana kwapamwamba kwa Grade"E"elastomer kumalola kugwiritsa ntchito madzi otentha kufika pa +230 F/+110C.Gasket'E" ndipamwamba kuposa momwe zimakhalira komanso kutentha kwa gasiketi yam'mbuyomu, zida zotsika kwambiri komanso zotsika mphamvu, kukana mankhwala ndi alumali moyo.
