API607 Valve Tshuaj ntsuam cov ntsiab lus thiab txheej txheem
Kev ntsuas hluav taws kub ntawm kev lag luam li qub feem ntau yog ua raws li cov kauj ruam hauv qab no:
- Npaj cov qauv valve thiab paub meej tias cov kev qhia tshwj xeeb thiab cov qauv ua tau raws li qhov yuav tsum tau ua.
- Nruab lub valve nyob rau hauv cov khoom kuaj, txuas cov pa roj thiab ntsuas ntsuas.
- Siv lub zog ua haujlwm los xyuas qhov kev sib khi ntawm lub valve ntawm chav tsev kub.
- Pib lub tshuab cua sov thiab ua kom sov lub valve raws li API607: 2016 tus qauv kub nkhaus, nrog rau lub sijhawm ntev ntawm 30 feeb.
- Saib xyuas qhov kev sib khi ua haujlwm thaum lub sijhawm cua sov kom ntseeg tau tias lub valve tsis muaj qhov txawv txav.
- Thaum tshav kub kub thiab txias rau chav tsev kub, thiab sim lub sealing thiab qhib / kaw kev ua tau zoo ntawm lub valve.
- Npaj cov ntaub ntawv xeem thiab sau cov ncauj lus kom ntxaws soj ntsuam, suav nrog cov ntaub ntawv tseem ceeb xws li tus nqi xau thiab hloov torque.
- Tag nrho cov txheej txheem yog nruj me ntsis raws li cov qauv, thiab tej yam txawv txav nyob rau hauv ib qho kev sib txuas yuav cuam tshuam rau kev xeem.
Hom Valves loj rau API 607
API 607 yog tsim tshwj xeeb rau lub quarter tig li qub, uas feem ntau siv cov ntsaws ruaj ruaj.
1. Pob Valves - Feem ntau API 607 Valve
Pob li qub yog qhov tseem ceeb tshaj plaws ntawm daim ntawv pov thawj hluav taws kub. Yuav kom dhau API 607, pob li qub yuav tsum muaj cov qauv "secondary metal to metal seal".
Floating Ball Valves: Siv rau cov kab me me, nruab nrab thiab qis. Thaum hluav taws kub, tus kheej kheej yog compressed thiab txav mus rau hauv qab, nias tiv thaiv daim di ncauj ntawm lub rooj zaum hlau valve.
Trunnion Mounted Pob Valves: Siv rau qhov loj diameters thiab siab siab. Lub rooj zaum hlau valve, uas tso siab rau lub caij nplooj ntoos hlav thauj khoom, nias tawm tsam tus kheej tom qab lub foob muag muag tawm.
2. Npauj Npaim Valves - Kev Ua Haujlwm Siab thiab Triple Eccentricity
High Performance / Ob Chav Offset Npauj Npaim Valve: Tsim los nrog lub nplhaib tshwj xeeb sealing (feem ntau yog ib lub foob mos qhwv hauv ib lub nplhaib hlau), nws tso siab rau cov hlau sib txuas kom kaw tom qab hluav taws kub.
Triple Offset Npauj Npaim Valve: Txawm hais tias triple offset feem ntau yog hlau foob, yog tias nws los nrog cov tsis muaj -hlau auxiliary foob, nws kuj yuav tsum tau ntawv pov thawj raws li API 607.
3. Plug li qub
Hauv ob sab phlu valve los yog eccentric plug valve: feem ntau yog siv nyob rau hauv kev lag luam tshuaj los tiv thaiv ib tug loj npaum li cas ntawm nruab nrab to nyob rau hauv hluav taws kub.
4. Tswj li qub
Lub pob valve lossis npauj npaim valve actuator sib dhos siv nyob rau hauv kev kaw thaum muaj xwm txheej ceev (ESD) hauv petrochemicals feem ntau xav kom cov seem valve ua raws li API 607.
Kev siv ntawm API 607 Valves
Cov li qub no feem ntau yog ntsia rau hauv cov chaw uas muaj hluav taws xob thiab cov xov xwm tawg tau raug tswj xyuas thiab muaj kev pheej hmoo ntawm hluav taws kub:
1. Refineries & Petrochemical Cog
Qhov no yog lub khw loj tshaj plaws rau API 607 li qub.
Daim ntawv thov cov ntsiab lus: Ntshuam thiab xa tawm cov ntaub ntawv hauv cov roj crude distillation units, hydrocracking, catalytic cracking thiab lwm yam units. Yog tias hluav taws tshwm sim, cov li qub no yuav tsum muaj peev xwm txiav tawm cov roj los tiv thaiv 'hluav taws kub'.
2. Roj thiab Gas Cia thiab Terminal (Tank Farms & Terminals)
Daim ntawv thov taw tes: Tank Base li qub rau cov tso tsheb hlau luam loj. Thaum hluav taws kub hnyiab tau tshwm sim, lub hauv paus valve yuav tsum muaj peev xwm nyob ze kom tiv thaiv tau kaum tawm txhiab tons ntawm cov roj crude los yog cov roj tiav los ntawm kev xau.
3. Offshore Platforms
Daim ntawv thov taw tes: Vim muaj qhov chaw tsawg ntawm hiav txwv thiab muaj teeb meem hauv kev khiav tawm hluav taws, txhua qhov hluav taws xob nruab nrab yuav tsum siv cov li qub uas ua raws li API 607 (los yog nruj dua API 6FA).
4. Gas Turbine thiab Fais Fab Kev Lag Luam
Daim ntawv thov point: Roj / roj system rau roj turbines. Yog tias lub kaw lus pom qhov xau lossis hluav taws kub, qhov hluav taws kub -tiv thaiv valve yuav tsum muaj peev xwm xyuas kom meej tias cov khoom siv roj raug txiav tag nrho.
5. Tshuaj cia thiab ntim
Cov ntsiab lus thov: Chaw thau khoom crane, methanol lossis ethanol cia chaw.

FAQ
Qhov txawv ntawm API 6FA thiab API 607 yog dab tsi?
API 607 muab cov qauv ntsuas hluav taws rau peb lub hlis twg- tig li qub thiab lwm yam li qub nrog lub rooj zaum tsis yog xim hlau nyob rau hauv siab, qhov API 6FA muab cov kev ntsuas hluav taws kub rau API 6A thiab API 6D li qub. API 6FA muaj feem xyuam rau cov hlau zaum li qub.
Dab tsi yog qhov txawv ntawmAPI 608thiab API 607?
API 607 yog qhov tseem ceeb rau cov cheeb tsam uas muaj kev nyab xeeb hluav taws yog qhov tseem ceeb tshaj plaws, kom ntseeg tau tias cov li qub tuaj yeem tiv taus thiab ua haujlwm thaum raug hluav taws. Nyob rau hauv sib piv, API 608 tsom rau cov qauv kev ncaj ncees thiab kev ua tau zoo ntawm cov hlau pob li qub nyob rau hauv siab thiab kub yam tsis hais txog hluav taws kub.
