Carbon Steel Flanged Trunnion Pob Valve
Carbon Steel Flanged Trunnion Pob Valve
Cov Carbon Steel Flanged Trunnion Ball Valve yog tsim los rau siab - siab, loj - txoj kab uas hla, thiab cov kev pabcuam cais tseem ceeb hauv kev xa roj & roj, kev ua roj av, LNG terminals, thiab lub tshuab tsim hluav taws xob.
Tsis zoo li ntab pob li qub, lub trunnion-mounted tsim txhawb lub pob ntawm ob sab sauv thiab qis bearings, txo qis kev khiav hauj lwm torque thaum ua kom ruaj khov, bi-kev taw qhia sealing kev ua tau zoo nyob rau hauv siab sib txawv siab.
Cov qauv tsim no tau xaiv dav dav hauv cov haujlwm EPC thoob ntiaj teb thiab ntev -kab raj xa dej, qhov twg kev ntseeg siab, kev nyab xeeb, thiab kev ua kom zoo rau lub neej yog qhov tseem ceeb.
Vim li cas Trunnion Pob Valve rau Siab -Kev Pabcuam Siab?
Txoj Cai Engineering
Nyob rau hauv floating pob li qub, kab siab yuam lub pob tawm tsam lub rooj zaum hauv qab, ua rau:
- Kev ua haujlwm siab torque hauv qhov loj
- Accelerated lub rooj hnav nyob rau hauv siab
- Tsis ruaj tsis khov sealing nyob rau hauv high differential siab tej yam kev mob
Trunnion Solution
Tus tsim trunnion daws cov teeb meem no los ntawm cov khoom siv thauj khoom faib khoom:
- Pob yog tsau los ntawm sab sauv thiab sab trunnions
- Kab siab yog pauv mus rau bearings es tsis txhob zaum
- Caij nplooj ntoos hlav- cov rooj zaum thauj khoom kom muaj kev sib txuas txuas ntxiv
Cov txiaj ntsig Engineering
- 40-70% qis ua haujlwm torque vs ntab pob li qub
