AN (Aerospace Cov Qauv) cov xov yog ib hom tshwj xeeb uas siv los txuas cov hoses uas yoog tau thiab lub tog raj hlau uas muaj kua txaus. Nws yog tsim rau MIL-F-5509 rau ib qho (Huab Cua - Tshav Dav Hlau Aeronautical Txuj) thiab THIAB (Cua Force Navy Aeronautical Tus Qauv Tsim Qauv) .. AN fittings yog cov nplaim taws haum, siv 37 ° flared tubing los ua cov hlau-hlau foob.
SAE xov yog Kev Lag Luam 37 degree flare fittings yog cov khoom tsim kom tau raws li SAE J514 / ISO-8434-2. Cov xov ncaj yog ib MIL-S-8879C tam sim no SAE-AS8879 .. Qhov sib txawv ntawm AN thiab SAE xov cuam tshuam rau cov xov chav kawm thiab cov duab (nruj npaum li cas haum cov xov yog), thiab cov khoom siv hlau siv.Ua raws:
AN xov Fitting: 1 / 2-20 UNJF-3B
SAE Industrialfitting: 1 / 2-20 UNF-2B
NPT Yeeb Nkab Xov: NPT yeeb nkab xov yog koj li kev cai xov kab xov kab thiab tau siv rau 100 xyoo. Lawv muaj nyob rau hauv kev ua haujlwm siab ntawm cov hlau dub thiab tooj dag, thiab cov hlau uas muaj siab thiab stainless hlau. Cov qauv sib txuas no yog siv hauv cov tshuab pneumatic thiab cov txheej txheem thiab cov tshuab hydraulic.
Nco ntsoov tias 37 ° AN thiab 45 ° SAE fittings thiab cov cuab yeej tsis tuaj yeem hloov tau vim muaj qhov sib txawv ntawm lub kaum ntse ntse. Kev sib tov rau lawv tuaj yeem ua rau xau ntawm qhov dej.
