Kala Duwanaanshaha Agabka
Bir been abuur ah:
Birta been abuurka ah waxaa lagu soo saaraa iyadoo la kululeeyo birta birta ah oo lagu qaabeeyo cadaadis sare. Habkani waxa uu wanaajiyaa qaab-dhismeedka hadhuudhka, taas oo keentay in xoog farsamaysan oo heersare ah, adkaanta, iyo iska caabinta jawiyada heerkulka/cadaadiska sareeyo. Darajooyinka caadiga ah waxaa ka mid ahBirta Kaarboon (ASTM A105)iyoSida ASTM A182.
Birta Cas:
Birta shubka ahi waxa ay samaysaa iyada oo birta dhalaalaysa lagu shubo caaryaal. Iyadoo kharash-ku-ool ah qaababka adag, waxay soo bandhigi kartaa porosity ama iswaafaqla'aan, xaddidaya isticmaalkeeda xaaladaha daran. Darajooyinka caadiga ah waxaa ka mid ah ASTM A216 WCB ( steel carbon) iyo ASTM A351 CF8M
Farqiga Muhiimka ah ee udhaxeeya Valve Birta Been Abuurka ah iyo Walxaha Birta ah ee Cast
| Halbeegga | Valves bir been abuur ah | Dabaqyada birta ah |
| Baaxadda cabbirka | Ka yar (DN15–DN200, ½”–8″) | Ka weyn (DN50–DN1200, 2″–48″) |
| Qiimaynta Cadaadiska | Sare (Fasalka 800-4500) | Dhexdhexaad (Fasalka 150-600) |
| Heerkulka | -29°C ilaa 550°C | -29°C ilaa 425°C |
| Codsiyada | Dhuumaha cadaadiska sarreeya, sifaynta | Nidaamyada cadaadiska hooseeya/dhexdhexaadka ah, biyaha |
Kala soocida Valve

2. Valves Been Abuurka Bir GlobeXakamaynta socodka saxda ah ee uumiga ama adeegyada kiimikada.
3. Walalka Hubinta Birta Been abuurka ahKahortagga dib-u-socodka kombaresarada ama bambooyinka (noocyada lulida/qaadista).
4. Daboolka Kubadda Birta ee Been-abuurka ahDaminta degdega ah ee dhuumaha kaarboon-karboon ee heerka 800.
Dabaqyada birta ah
1. Dabaqyada Albaabka Birta Cast (Fasalka 150-300): Go'doominta dareeraha badan ee daaweynta biyaha.
2. Cast Steel Globe Valves: Nidaaminta socodka guud ee nidaamyada HVAC.
3. Tuubbooyinka Hubinta BirtaXalka qiimaha jaban ee adeegyada aan muhiimka ahayn.
Maxaa DoortayFasalka 800 ee Walxaha Birta Been abuurka ah
Heerka 800 ee alwaaxyada birta ee been abuurka ah waxay u adkeysan karaan cadaadiska ilaa 1380 bar (20,000 psi) at 38°C, taasoo ka dhigaysa mid ku habboon:
- Haamaha shidaalka ee xeebaha
- Xadhkaha uumiga heerkulka sare
- Warshad ka shaqaynaysa hydrogen
Gabagabo
Albaabada birta la been abuurtaysi fiican ugu fiicnaadaan jawiga walaaca sare leh sababtoo ah dhismahooda adag, halka tuubada birta ah ee la tuuray ay bixiyaan xalal dhaqaale oo waaweyn, nidaamyada cadaadiska hooseeya. Xulashada nooca saxda ah waxay kuxirantahay shuruudaha hawlgalka, miisaaniyada, iyo heerarka warshadaha sida ASME B16.34.
