Chav Kawm 600 Vuam Neck Flange qhov ntev, raws li ASME B16.5 tus qauv, sib txawv raws li cov yeeb nkab nominal loj (NPS) ntawm flange. Hauv qab no yog qhov dav dav rau Chav Kawm 600 Vuam Neck Flange rau ntau qhov ntau thiab tsawg:
Nominal Pipe Size (NPS):Feem ntau yog nyob ntawm 1/2 nti (DN 15) txog 24 ntiv tes (DN 600) thiab loj dua.
Sab nraud txoj kab uas hla (OD):OD txawv nyob ntawm NPS. Piv txwv li, OD ntawm 1/2-inch flange yog kwv yees li 4.75 ntiv tes, thaum OD ntawm 24-inch flange yog nyob ib ncig ntawm 33.38 ntiv tes.
Bolt Circle Diameter (BCD):Qhov no dimension nce nrog qhov loj ntawm flange. Piv txwv li, BCD ntawm 1/2-inch flange yog kwv yees li 3.5 ntiv tes, thaum BCD ntawm 24-inch flange yog nyob ib ncig ntawm 29.5 ntiv tes.
Number of Bolt Qhov:Tus naj npawb ntawm lub qhov ntsia hlau sib txawv nyob ntawm NPS. Cov qhov me me tuaj yeem muaj qhov bolts tsawg dua (piv txwv li, 4), thaum qhov loj dua tuaj yeem muaj ntau dua (piv txwv li, 20).
Bolt Qhov Diameter:Txoj kab uas hla ntawm lub qhov ntsia hlau sib txawv nrog NPS. Piv txwv li, lub qhov taub lub qhov taub rau 1/2-inch flange yog kwv yees li 0.88 ntiv tes.
Hub Diameter:Txoj kab uas hla ntawm lub ntsej muag tsa ntawm lub hauv paus ntawm flange nce nrog qhov loj ntawm flange.
Zuag qhia tag nrho Length los ntawm Hub (LTH):Qhov loj me no, uas yog qhov kev ncua deb ntawm lub ntsej muag ntawm flange mus rau qhov kawg ntawm lub hub, kuj nce nrog qhov loj ntawm flange.
Flange Thickness:Lub thickness ntawm flange sib txawv raws li cov chav kawm siab.
Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias qhov loj me no yog qhov dav dav thiab qhov ntev tshwj xeeb yuav txawv raws li cov chaw tsim khoom thiab cov qauv ua raws. Rau qhov tseeb thiab cov ncauj lus kom ntxaws, nws raug nquahu kom xa mus rau ASME B16.5 tus qauv lossis sab laj cov chaw tsim khoom tshwj xeeb rau qhov tshwj xeeb flange loj thiab chav kawm.
