Kodi Bellow Seal Globe Valve ndi chiyani: Ultimate Guide

Kumvetsetsa Bellow Seal Globe Valves

Avalavu ya globe yosindikizidwandi valavu yapadera yotseka yopangidwa kuti ithetse kutayikira kwa tsinde pazovuta kwambiri. Mosiyana ndi mavavu achikhalidwe odzaza padziko lonse lapansi, imagwiritsa ntchito chitsulo chachitsulo chomangirira ku tsinde ndi ma valve, ndikupanga chisindikizo cha hermetic. Kapangidwe kameneka ndi kofunikira kuti muzitha kuthana ndi zinthu zapoizoni, zowononga, kapena zoyera kwambiri pomwe zinthu zotuluka m'malo osavomerezeka ndizosavomerezeka.

Zigawo Zofunikira za Bellow Seal Globe Valves

1. Bellows Assembly

• Zofunika:Chitsulo chosapanga dzimbiri (SS316/316L), Inconel 625, kapena Hastelloy C276
• Kupanga:Multi-ply convolutions (8-12 zigawo) kwa 10,000+ kulimba kwa kuzungulira
• Ntchito:Makanikiza / amatambasula panthawi yogwira ntchito ya valve ndikusunga kukhulupirika kwa chisindikizo

2. Thupi la Vavu

• Pressure Rating:Kalasi 150 mpaka Kalasi 2500 (ANSI/ASME B16.34)
• Malizani maulumikizidwe:Flanged (RF/RTJ), socket weld, kapena buttweld
• Temp Range:-196°C mpaka 550°C (cryogenic to high-heat)

3. Tsinde & Chimbale

• Integral forged stem-disc msonkhano kuti mugwirizane
• Kulimbitsa pamwamba (Stellite 6 coating) pofuna kukana abrasion

4. Chisindikizo Chachiwiri (zosunga zobwezeretsera)

• mphete zonyamula ma graphite m'munsimu zimakhala ngati zolephera

Momwe Bellow Seal Globe Valve Imagwira Ntchito

Khwerero 1: Kutsegula Vavu

Pamene gudumu lamanja likuzunguliridwa motsata koloko:

• Tsinde limakwera, kukweza chimbale kuchokera pampando
• Mavuvu compress axially, kusunga chisindikizo kukhulupirika

Khwerero 2: Kutseka Vavu

Kuzungulira kozungulira:

• Tsinde limakakamiza chimbale motsutsana ndi mpando, kuyimitsa kutuluka
• Mavuvu amafikira kutalika koyambirira

Gawo 3: Kupewa Kutayikira

Kusindikiza kawiri:

• Chisindikizo choyambirira: Njira yodutsira tsinde la Bellows block
• Chisindikizo chachiwiri: Kulongedza kwa graphite (API 622 ikugwirizana)

Ubwino Woposa Mavavu a Standard Globe

Industrial Applications

1. Chemical Processing

• Zomera za chlor-alkali (zosungira gasi wa chlorine)
• Kupanga kwa Pharmaceutical API

2. Mafuta & Gasi

• HF alkylation mayunitsi
• Kusintha kwa LNG cryogenic (-162°C)

3. Kupanga Mphamvu

• Kupatula madzi a boiler
• Ma turbine bypass systems

Zosankha Zosankha

1. Mtundu wa Bellows

• Mitundu Yopangidwa:Kupanikizika Kwambiri (ASME Class 1500+)
• Ma Welded Bellows:Media Corrosive (electropolished finish)

2. Makhalidwe Oyenda

• Maperesenti ofanana ndi mayendedwe a mzere wamapulogalamu owongolera

3. Zitsimikizo

• NACE MR0175 ya utumiki wowawasa
• PED 2014/68/EU pamisika yaku Europe

Opanga apamwamba aku China Bellow Valve

Opanga aku China ngati NSW Valve Manufacturer amapereka:

• API 602/BS 1873 yogwirizana ndi mapangidwe
• 30% kupulumutsa mtengo motsutsana ndi mitundu yaku Europe
• Kuyesa kwa mvuvu mwamakonda (kuzindikira kutayikira kwa helium)

Kusamalira Njira Zabwino Kwambiri

• Kuyendera kwapachaka kwa ming'alu ya kutopa
• Kupaka tsinde ndi mafuta otentha kwambiri
• Pewani kuthamanga mopitilira muyeso (max 50 Nm pa mavavu a DN50)
