Kev kub siab pob valve VS tsis tshua muaj siab pob li qub
Siab -siab: Ntau dua lossis sib npaug rau PN100 (Class 600)
Tsawg-siab: Tsawg dua lossis sib npaug rau PN40 (Class 300)
| Parameter | Siab -Pressure Ball Valves | Tsawg-Pressure Ball Valves |
|---|---|---|
| Tsim | 1. Khoom siv lub cevKhoom siv: ASTM A105 / A182 F316 2. Kev sib khi: Hlau rooj + caij nplooj ntoos hlav-loaded mechanisms 3. Txhawb nqa: Trunnion-mounted tsim 4. Kev sib txuas: Tag nrho welded / Flanged (RF / RJ) |
1. Khoom siv lub cevKhoom siv: cam khwb cia hlau (WCB / CF8) 2. Kev sib khi: Cov rooj zaum mos (PTFE / PEEK) 3. Txhawb nqa: Floating pob 4. Kev sib txuas: Flanged (RF) / Threaded |
| Kev ua tau zoo | - Siab: Chav Kawm 600 ~ 2500 - Kub: -196℃~ +550 degree - Kev Leakage: Tsawg dua lossis sib npaug rau ISO 5208 Rate A (Xoom Leakage) - Fire Safe: API 607/6FA tau ntawv pov thawj |
- Siab: Chav Kawm 150 ~ 300 - Kub: -29℃~ +200 degree - Kev xau: ISO 5208 Rate D - Tsis muaj hluav taws kub - yuav tsum muaj kev nyab xeeb |
| Daim ntawv thov | - Roj/gas kis pipelines (Ntau dua los yog sib npaug rau Class 600) - Hydrocracking units - Supercritical steam systems - HP dej / roj txhaj qhov dej |
- Kev kho dej / HVAC - Tsawg- siab faib roj - Cov txheej txheem tshuaj - General industrial flow control |
| Nqi & Kho | - Tus nqi siab dua (forging + complex design) - Lub neej ua haujlwm txuas ntxiv (30+ xyoo) - Kev kho tshwj xeeb yuav tsum tau ua |
- Tus nqi qis (casting + simplified design) - Kev saib xyuas yooj yim (hauv -kab kho tau) - Standardized spare qhov chaw |
