Pob li qubyog cov feem ntau siv li qub hauv kev lag luam thiab kev lag luam tswj cov kua dej. Lawv tsim yooj yim, durability, thiab txhim khu kev qha sealing ua rau lawv zoo tagnrho rau cov ntawv thov kom ceev ceev shutoff los yog khiav kev cai. Ntawm ntau hom pob li qub,puv chaw nres nkoj pob li qubsawv tawm rau lawv qhov tshwj xeeb tsim thiab kev ua tau zoo. Hauv tsab xov xwm no, peb yuav tshawb xyuas qhov chaw nres nkoj pob valve yog dab tsi, nws txawv li cas ntawm qhov chaw nres nkoj txo qis, nws cov yam ntxwv tseem ceeb ntawm kev ua haujlwm, thiab nws cov kev siv feem ntau.
Dab tsi yog Pob Valve
Ib pob valveyog lub quarter-tig valve uas siv lub hollow, rotating pob nrog lub qhov (qhov) los ntawm nws qhov chaw los tswj cov kua dej. Thaum lub valve qhib, lub bore txuas nrog lub raj xa dej, tso cai rau cov dej nkag mus. Tig lub pob 90 degrees siv tus kov lossis actuator kaw lub valve, thaiv qhov ntws. Pob li qub yog paub rau lawv:
- Kev ua haujlwm ceev(qhib / kaw hauv vib nas this).
- Bidirectional sealing(Flow tuaj yeem txav mus rau ob qho tib si).
- Tsis tshua muaj siab poobthaum qhib tag nrho.
- Durabilitynyob rau hauv high-pressure los yog high-temperature ib puag ncig.
Pob li qub yog categorized los ntawm qhov chaw nres nkoj loj, tsim, thiab cov khoom siv. Covchaw nres nkoj loj- xa mus rau txoj kab uas hla ntawm lub bore - ua lub luag haujlwm tseem ceeb hauv kev txiav txim siab lub peev xwm ntawm lub valve thiab kev poob siab.
Dab tsi yog Qhov Chaw Nres Nkoj Pob Valve
Atag nrho port pob valve(tseem hu ua apuv pob valve) yog tsim los nrog ib txoj kab uas hla uas phim covsab hauv txoj kab uas hla (ID) ntawm cov kav dej txuas. Piv txwv li, yog tias lub valve tau teeb tsa hauv 4-nti raj, lub qhov khoob ntawm qhov chaw nres nkoj pob valve tseem yuav ntsuas 4 ntiv tes. Qhov kev tsim no tshem tawm cov kev txwv ntws, kom ntseeg tau tias qhov tsawg kawg nkaus poob siab thiab qhov siab tshaj plaws ntws.
Cov yam ntxwv tseem ceeb ntawm Full Port Ball Valves:
- Qhov Loj:Haum rau lub raj xa dej sab hauv.
- Lub Cev Tsim:Lub cev lub cev loj dua piv rau qhov txo qhov chaw nres nkoj kom haum rau lub pob tag nrho.
- Flow Efficiency:Yuav luag xoom siab poob thaum qhib tag nrho.
- Daim ntawv thov:Qhov zoo tshaj plaws rau cov tshuab uas yuav tsum tau txwv tsis pub khiav los yog npua (tu / tu).
Full Port Ball Valve vs. Txo Port Ball Valve
Thawj qhov sib txawv ntawm qhov chaw nres nkoj puv thiab txo qhov chaw nres nkoj pob li qub nyob hauv lawvqhov loj:
| Feature | Port Pob Valve | Txo qhov chaw nres nkoj pob Valve |
|---|---|---|
| Lub taub hau | Sib piv cov kav dej ID (piv txwv li, 4 "valve = 4" ID) | Tsawg dua tus kav dej ID (piv txwv li, 4 "valve = 3" ID) |
| Siab poob | Tsawg kawg rau tsis muaj | Siab dua vim muaj kev txwv ntws |
| Flow Capacity | Qhov siab tshaj plaws | Txo los ntawm 20-50% |
| Valve Loj & Qhov hnyav | Loj dua thiab hnyav dua | Compact thiab lub teeb yuag |
| Nqi | Siab dua | qis |
| Daim ntawv thov | High-flow, pigging, slurries | General-purpose, nqi-sensitive systems |
Thaum twg los xaiv Full Port Ball Valves:
- Systems xav tautxwv tsis pub khiav(piv txwv li, kev tiv thaiv hluav taws, kev siv dej).
- Cov kav dej uas xav taunpua(cov cuab yeej ntxuav tau dhau los ntawm kab).
- tuavkua nplaum, slurries, los yog abrasive media.
Thaum twg los xaiv Txo Cov Port Valves:
- Nyiaj txiag-paub tej yaam num nrogkev xav tau dej ntws nruab nrab.
- Cov kab ke uas qhov chaw lossis qhov hnyav yog qhov txwv.
Cov yam ntxwv ua haujlwm ntawm qhov chaw nres nkoj pob li qub
1.Zero Flow txwv
Lub bore tag nrho ua kom cov kua ntws ncaj nraim los ntawm lub valve yam tsis muaj kev kub ntxhov lossis poob siab. Qhov no yog ib qho tseem ceeb nyob rau hauv high-flow systems xws li dej faib los yog roj pipelines.
2.Pigging Compatibility
Tag nrho cov chaw nres nkoj li qub tso cainpua(kev ntxuav lossis tshuaj xyuas cov khoom siv) kom dhau los ntawm cov raj xa dej tsis muaj kev cuam tshuam, ua rau lawv tseem ceeb hauv kev lag luam roj thiab roj, tshuaj, thiab dej khib nyiab.
3.Bidirectional Sealing
Tag nrho qhov chaw nres nkoj pob li qub foob sib npaug zoo hauv ob qho kev qhia ntws, muab kev yooj yim hauv kev tsim qauv.
4.Durability hauv Harsh Media
Lub bore du thiab robust tsim (feem ntau nyob rau hauv stainless hlau los yog alloys) tiv taus yaig los ntawm abrasive los yog corrosive kua.
5.Kev tu yooj yim
Muaj ntau qhov chaw nres nkoj valve feature asplit-lub cev tsim, tso cai rau kev nkag tau yooj yim rau cov khoom siv sab hauv los ntxuav lossis kho.
Dab tsi yog Qhov Chaw Nres Nkoj Pob Valve Siv Rau
Tag nrho cov chaw nres nkoj pob li qub tau xa mus rau hauv kev lag luam uas qhov kev ua haujlwm zoo, pigging, lossis kev tshaj tawm kev sib raug zoo yog qhov tseem ceeb:
1.Roj & Roj Pipelines
- Kev thauj cov roj av, roj av, lossis cov khoom ua kom zoo.
- Enabling pigging rau pipeline tshuaj xyuas thiab tu.
2.Dej & Dej pov tseg Systems
- Municipal water supply networks.
- Slurry tuav hauv cov chaw kho dej phwj.
3.Kev ua tshuaj lom neeg
- Hloov cov tshuaj viscous lossis abrasive (xws li, polymers, acids).
4.Kev Tiv Thaiv Hluav Taws Xob
- Xyuas kom cov dej ntws siab tshaj plaws thaum muaj xwm txheej ceev.
5.Lub zog tiam
- Dej txias tshuab hauv nuclear lossis thermal nroj tsuag.
6.Marine & Shipbuilding
- Kev hloov pauv roj thiab kev tswj dej ballast.
Xaus
A tag nrho port pob valveyog ib qho kev ua haujlwm siab valve tsim rau cov tshuab xav tauunrestricted flow, pigging muaj peev xwm, thiab tsawg kawg siab poob. Thaum nws loj dua thiab raug nqi ntau dua li qhov txo qhov chaw nres nkoj, nws qhov zoo hauv cov ntawv thov tseem ceeb - xws li cov kav dej, kev tiv thaiv hluav taws, thiab slurry tuav - ua rau nws tseem ceeb. Los ntawm kev nkag siab qhov sib txawv ntawm qhov chaw nres nkoj tag nrho thiab txo qhov chaw nres nkoj pob li qub, engineers thiab cov neeg ua haujlwm tuaj yeem xaiv txoj cai valve kom ua kom zoo dua qub, txo cov nqi ua haujlwm, thiab txuas ntxiv lub neej ntev.
