Feem ntau hom pob li qub hauv kev lag luam roj thiab roj yog categorized los ntawm lawvpob kev txhawb nqa tsim(Floating vs. Trunnion),lub cev sib dhos(Sab nkag, Sab saum toj nkag, lossis tag nrho-Welded), thiabqhov loj(Full Bore vs. Txo Bore). Feem ntau yuav tsum ua raws li covAPI 6D UASstandard rau pipeline kev pab.

API 6D Pob Valve Classification (Kev tsim kho & sib dhos)
| Qeb | Valve Hom (Standard Terminology) | Technical Features & API 6D Requirements |
| Pob Txhawb Tsim | Floating Pob Valve | Lub pob tau txais kev txhawb nqa los ntawm cov rooj zaum thiab txav mus rau hauv qab dej siab. Feem ntau txwv rau qhov ntau thiab tsawg hauv qab noNPE 10 (DN250)thiab Chav Kawm 150-300. |
| Trunnion Mounted Pob Valve (TMBV) | Lub pob yog tsau los ntawm sab sauv thiab qis bearings (trunnion). Covtxheem configurationrau loj-dhau, siab- siab API 6D kav dej; muab torque tsawg thiab ruaj khov sealing. | |
| Lub cev sib dhos hom | Sab Nkag (Split Lub Cev) | Muaj nyob rau hauv 2-thooj los yog 3-thooj bolted designs. Hom ntau tshaj; yooj yim rau kev tsim thiab tswj rau cov kev pabcuam kav dej. |
| Sab saum toj nkag pob Valve | Nta ib lub cev monolithic (ib -daim) lub cev. Txhawb nqaHauv - kab Maintenance, tso cai rau kev kho yam tsis tau tshem lub valve ntawm cov kav dej welded. | |
| Fully Welded Lub cev Valve | Lub cev yog tag nrho kaw los ntawm welding tsis muaj bolted pob qij txha. Tshem tawm txoj kev tawm sab nraud; zoo tagnrho raufausgas kis pipelines. |
Bore & Functional Classification Table
| Yam khoom | Hom | API 6D Txhais & Tus Nqi |
| Lub taub hau | Full Bore (FB) | bore txoj kab uas hla ua raws li API 6D Table 1. Txhawb nqaNpuakev khiav hauj lwm nrog tsawg kawg nkaus tsis kam. |
| Reduced Bore (RB) | Lub bore yog me dua li lub raj xa dej. Muab torque qis thiab nqi; tsis haum rau cov kav dej uas xav tau pigging. | |
| Sealing Function | Ob Chav Thaiv & Bleed (DBB) | Nyob rau hauv txoj hauj lwm kaw, ob lub rooj sib khi tiv thaiv lub siab ib txhij, thiab cov kab noj hniav tuaj yeem raug tso tawm kom paub tseeb tias kev foob kev ncaj ncees.Standard API 6D configuration. |
| Ob chav cais & Bleed (DIB-1 / DIB-2) | Muab kev cais ob. Txawm hais tias ib lub rooj zaum tsis ua haujlwm, lwm tus tuav kev sib khi los ntawm kev siv tshuab lossis kua dej. | |
| Hom kev ua haujlwm | Phau ntawv, Gear, Actuated | API 6D li qub feem ntau xav tau cov actuators (Pneumatic, Hydraulic, lossis Hluav Taws Xob) thiab yuav tsum muaj cov mounting pads ua raws li tus qauv qhov ntev. |
Cov khoom siv tseem ceeb & Cov yam ntxwv tseem ceeb rau API 6D Valves
| Nta | Kev piav qhia | Daim ntawv thov tseem ceeb |
| Kev txhaj tshuaj xwm ceev | Fittings rau txhaj tshuaj sealant rau hauv lub rooj zaum thiab qia. | Muab lub foob thib ob ib ntus yog tias lub rooj zaum muag muag puas lawm. |
| Anti-Static Device | Ua kom muaj hluav taws xob txuas ntxiv ntawm lub pob, qia, thiab lub cev. | Tiv thaiv kom tsis txhob muaj hluav taws kub hnyiab hauv cov roj tawg thiab cov pa roj. |
| Anti-Blowout Stem | Features lub xub pwg nyom tsim (internal nkag). | Tiv thaiv lub qia los ntawm ejected nyob rau hauv siab thaum lub sij hawm packing txij nkawm. |
| Hluav taws kub-Safe Design | Certified rauAPI 607 Covlos yogAPI 6FA UAS. | Xyuas kom lub foob hlau thib ob tseem nyob ruaj khov yog tias cov ntsaws ruaj ruaj muag muag thaum muaj kev kub ntxhov ntawm - kub kub. |

FAQ
Dab tsi yog natural gas pob valve
Natural gas pob li qubyog cov cuab yeej tswj xyuas tseem ceeb hauv cov tshuab hluav taws xob xa hluav taws xob, feem ntau yog siv hauv petrochemical, chaw nres tsheb roj av, cua sov tes hauj lwm, thiab kev lag luam shipbuilding. Cov li qub no muaj cov qauv tsim los yog qhov ruaj khov, hnav tsis kam, zoo sealing kev ua tau zoo, thiab kev ua haujlwm yooj yim, ua rau kev kaw -tawm, kev sib txuas, lossis kev cai ntawm cov raj xa dej tawm. Cov qauv sib txawv, xws li Q341F-16C thiab Q41F, yog qhov tsim nyog rau kev siv xws li ambient mus rau cryogenic liquefied natural gas, thiab muab kev xaiv ntawm phau ntawv thiab turbine tsav.
Qhov txawv ntawm API 6D thiab API 594 yog dab tsi?
API Standard 594 npog cov qauv tsim, cov ntaub ntawv, lub ntsej muag - mus rau - lub ntsej muag qhov ntev, siab- qhov ntsuas kub, thiab kev tshuaj xyuas, kev sim, thiab kev xeem yuav tsum tau ua rau ob hom kev kuaj xyuas li qub.
API SPEC 6D tau txais ISO 14313: 1999, Kev lag luam roj thiab roj-Cov kav dej thauj mus los-Cov kav dej. Cov txheej txheem thoob ntiaj teb no qhia meej thiab muab cov lus pom zoo rau kev tsim, tsim khoom, kuaj, thiab cov ntaub ntawv ntawm cov pob li qub, kos li qub, lub rooj vag li qub, thiab cov ntsaws li qub siv hauv cov kav dej.
