Ob chav Eccentric Flanged Npauj Npaim Valve Technical Specifications
Tsim Evolution
Qhov kev tsim kho siab tshaj plaws no suav nrog dual -axis offset geometry los txhim kho kev ua tau zoo tshaj li qub npauj npaim li qub. Lub configuration tshiab muab:
60-80% txo qis hauv kev ua haujlwm torque
Kev pabcuam txuas ntxiv (3-5 × tus qauv valve lifespan)
Txhim khu kev ua tau zoo nyob rau hauv huab cua txias (600℃/ PN40)
Engineering Advantages
Offset Geometry
Thawj qhov offset: Valve qia tshem tawm ntawm qhov chaw disc, tsim kom muaj txiaj ntsig zoo
Secondary offset: 5-15℃qia inclination ua kom tsis muaj kev sib txhuam thawj zaug
Flange Integration
Txheem flange ntsej muag (ANSI / GB / JIS)
Bolted kev twb kev txuas nrog siab-adaptive gaskets:
Siab -temp: Kauv-mob hlau / graphite
Corrosive media: PTFE-encapsulated
Sealing Technology
Hard Seal Option:
Disc ntug: Stellite 6 overlay (HRC 58-62)
Lub rooj zaum: 316L + hloov tau graphite matrix
Soft Seal Option:
EPDM / PTFE rau kev siv tshuaj / zaub mov qib
Bubble-tight shutoff (ANSI Class VI)
Kev ua haujlwm tau zoo
100,000-cycle endurance xeem (MSS SP-67)
Fugitive emissions<50ppm (ISO 15848-1)
Hluav taws kub- ntawv pov thawj nyab xeeb (API 607/ISO 10497)
Daim Ntawv Thov Kev Pabcuam
Fais fab nroj tsuag SO₂ scrubber cais
Delayed coker unit quench systems
Blast furnace gas rov qab circuits
LNG davhlau ya nyob twg muaj xwm ceev shutdown kab
Cov txiaj ntsig sib piv
| Feature | Standard Valve | Ob chav Eccentric |
|---|---|---|
| Torque Requirement | 100% | 40-60% |
| Kev Kho Vaj Tse | Txhua xyoo | 3-5 xyoos |
| Qhov kub thiab txias | -20 ~ 300 degree | -196 ~ 600 degree |
Tus qauv tsim kev ntseeg tau yog los ntawm kev txheeb xyuas qhov tseeb ntawm cov khoom siv kawg - kev faib tawm kev ntxhov siab zoo tshaj plaws thiab cov khoom siv kho qhov tawv tawv. Kev xaiv ntse positioner kev koom ua ke muaj rau kev lag luam 4.0 daim ntawv thov.
