Kusiyana kwa Zinthu Zakuthupi
Chitsulo Chopangidwa:
Chitsulo chopangidwira chimapangidwa ndi kutentha kwazitsulo zazitsulo ndikuzipanga pansi pa kupanikizika kwakukulu. Izi zimakulitsa kapangidwe ka tirigu, zomwe zimapangitsa kuti pakhale mphamvu zamakina apamwamba, kulimba, komanso kukana kupsinjika kwakukulu / kutentha. Magiredi wamba akuphatikizapoASTM A105 (carbon steel)ndiASTM A182 (chitsulo chosapanga dzimbiri).
Chitsulo Choponyera:
Chitsulo chotayira chimapangidwa pothira zitsulo zosungunuka mu nkhungu. Ngakhale ndizotsika mtengo pamawonekedwe ovuta, zitha kuwonetsa porosity kapena zosagwirizana, zomwe zimachepetsa kugwiritsidwa ntchito kwake mumikhalidwe yovuta kwambiri. Magiredi odziwika akuphatikizapo ASTM A216 WCB (carbon steel) ndi ASTM A351 CF8M (chitsulo chosapanga dzimbiri).
Kusiyana Kwakukulu Pakati pa Ma Valvu Achitsulo Opangidwa ndi Cast Cast Steel Valve
| Parameter | Ma Vavu Achitsulo Opangidwa | Ma Vavu Achitsulo Oponyera |
| Size Range | Zocheperako (DN15–DN200, ½”–8″) | Chachikulu (DN50–DN1200, 2″–48″) |
| Pressure Rating | Zapamwamba (Kalasi 800–4500) | Wapakati (Kalasi 150–600) |
| Kutentha | -29°C mpaka 550°C | -29°C mpaka 425°C |
| Mapulogalamu | Mapaipi apamwamba kwambiri, zoyenga | Machitidwe otsika / apakatikati, madzi |
Zigawo za Vavu
Ma Vavu Achitsulo Opangidwa
1. Mavavu Opangira Zipata Zachitsulo (Kalasi 800): Mapangidwe ang'onoang'ono odzipatula pamakina amafuta / gasi.
2. Mavavu opangidwa ndi Steel Globe: Kuwongolera kumayenda bwino mu nthunzi kapena ntchito zamakhemikhali.
3. Mavavu Opangira Zitsulo Zopangira: Pewani kubwerera m'mbuyo mu compressor kapena mapampu (mitundu ya swing/lift).
4. Ma Valves Opangidwa Ndi Mpira Wachitsulo: Kutseka mwachangu m'mapaipi a hydrocarbon a Class 800.
Ma Vavu Achitsulo Oponyera
1. Ma Vavu a Chipata Chachitsulo cha Cast (Kalasi 150–300): Kudzipatula kwamadzimadzi ambiri pochiza madzi.
2. Cast Steel Globe Valves: General flow regulation in HVAC systems.
3. Cast Steel Check Valves: Mayankho otsika mtengo a ntchito zosafunikira.
Chifukwa Chosankha?Kalasi 800 Zopangira Zitsulo Zachitsulo
Ma valve 800 opangira zitsulo amapirira kupanikizika mpaka 1380 bar (20,000 psi) pa 38 ° C, kuwapanga kukhala abwino kwa:
- Zopangira mafuta a Offshore
- Mizere yotentha kwambiri
- Malo opangira hydrogen
Mapeto
Mavavu opangira zitsuloamapambana m'malo opsinjika kwambiri chifukwa cha zomangamanga zolimba, pomwe mavavu achitsulo oponyedwa amapereka njira zothetsera mavuto akulu, otsika kwambiri. Kusankha mtundu woyenera kumadalira zofunikira pakugwira ntchito, bajeti, ndi miyezo yamakampani monga ASME B16.34.
