Ua kom muaj kev sib tw thoob plaws hauv zej zog, thaj chaw lag luam, thiab cov chaw pej xeem, cov dej tua hluav taws ua lub luag haujlwm tseem ceeb hauv kev ua kom muaj kev nyab xeeb thiab tiv thaiv cov zej zog.
Ua nrog kev ua haujlwm ntev thiab kev ua haujlwm hauv siab, cov hluav taws kub hydrants txuas nrog cov dej hauv nroog thiab tso cai rau cov neeg tua hluav taws kom txuas lawv cov hoses kom tiv thaiv hluav taws thiab tiv thaiv kev puas tsuaj. Dhau li ntawm lawv lub luag haujlwm tseem ceeb hauv kev teb thaum muaj xwm txheej ceev, cov dej tua hluav taws kuj tseem ua rau pej xeem paub txog kev nyab xeeb hluav taws thiab kev npaj.
Cov xim ci ntsa iab ntawm cov hluav taws kub hydrants feem ntau ntxiv qhov kov ntawm kev vibrancy rau hauv nroog txoj kev, ua rau lawv pom tau yooj yim thiab cim kev npaj thiab kev tiv thaiv. Zuag qhia tag nrho, hluav taws kub hydrants embody tus ntsuj plig ntawm kev saib xyuas hauv zej zog thiab ceev faj, sawv ua tus saib xyuas ruaj khov uas pab ua kom peb ib puag ncig muaj kev nyab xeeb thiab nyab xeeb.
Hluav Taws Hluav Taws Xob: Ib Daim Ntawv Qhia Tag Nrho
1. Taw qhia
A hluav taws hydrantyog ib qho tseem ceeb ntawm kev tiv thaiv hluav taws hauv nroog thiab kev lag luam. Nws muab cov dej nkag tau yooj yim rau kev tua hluav taws, ua rau cov neeg tua hluav taws tuaj yeem txuas cov hoses thiab tswj hluav taws kom zoo. Cov hluav taws kub hnyiab feem ntau txuas nrog lub zog xa hluav taws xob sib txuas thiab tau teeb tsa raws txoj kev, hauv cov chaw tsim khoom, thiab hauv thaj chaw muaj kev pheej hmoo siab -.
2. Hom Hluav Taws Xob Hluav Taws Xob
Cov hluav taws kub hnyiab tuaj yeem muab faib ua ntau hom hauv qab no:
2.1 Cov Hluav Taws Xob Hluav Taws Xob ntub dej
Cov kais dej ntub dej feem ntau yog siv rau hauv cov cheeb tsam uas qhov kub thiab txias tsis muaj kev txhawj xeeb. Hauv qhov kev tsim no, lub thoob hydrant yeej ib txwm muaj dej. Txhua lub qhov hluav taws xob yog tus kheej tswj los ntawm lub valve cais, tso cai rau ntau lub hoses txuas thiab ua haujlwm ib txhij.
Qhov zoo:
Yooj yim rau kev khiav lag luam
Kev tso dej sai sai
Ntau qhov hluav taws xob tuaj yeem ua haujlwm ntawm nws tus kheej
2.2 Dry Barrel Fire Hydrant
Cov kais dej qhuav yog tsim los rau cov huab cua txias uas khov tuaj yeem ua rau cov khoom puas. Lub ntsiab valve nyob hauv qab av, thiab lub thoob tseem qhuav thaum tsis siv. Cov dej ntws mus rau hauv lub hydrant tsuas yog thaum nws qhib.
Qhov zoo:
Tiv thaiv kom khov
Siv tau nyob rau hauv qis - qhov kub thiab txias ib puag ncig
3. Cov Cheebtsam tseem ceeb ntawm Cov Hluav Taws Xob Hluav Taws Xob
Ib qho hluav taws kub hydrant muaj xws li cov hauv qab no:
Kev sib txuas Inlet:Txuas lub hydrant mus rau cov dej hauv av
Main Valve:Tswj cov dej ntws
chim:Lub cev ntsug ntawm lub hydrant
Qhov hluav taws xob nozzles:Feem ntau suav nrog cov qhov hluav taws xob hose (piv txwv li, 2.5 ") thiab lub twj tso kua mis (piv txwv li, 4" lossis 4.5")
Kev ua haujlwm ceev:Siv los qhib lossis kaw lub hydrant nrog ib tug ciaj ntswj
Bonnet:Npog thiab tiv thaiv lub hauv paus mechanism
4. Cov qauv thiab specifications
Hluav taws kub hydrants yog tsim raws li ntau yam thoob ntiaj teb cov qauv, nyob ntawm seb cheeb tsam:
AWM C502- Feem ntau siv hauv Tebchaws Meskas rau cov kav dej qhuav
EN 14384 / EN 14339- Cov qauv European rau hluav taws kub hydrants
SIB 750- British tus qauv rau cov hluav taws kub hauv av
ISO cov qauv- Cov txheej txheem thoob ntiaj teb rau kev ua haujlwm thiab kev sim
Cov parameter tseem ceeb muaj xws li:
Nominal txoj kab uas hla (piv txwv li, 4", 6 ")
Ua haujlwm siab (piv txwv li, 150 PSI, 250 PSI)
Qhov ntau thiab tsawg thiab xov hom (NH, BS, Storz, thiab lwm yam)
Flow rate peev
5. Cov ntawv thov
Hluav taws kub hydrants yog dav siv nyob rau hauv:
Kev tiv thaiv hluav taws hauv nroog
Kev lag luam chaw(roj & gas, tshuaj nroj tsuag, warehouses)
Commercial tsev thiab complexes
Airports thiab ports
Cov chaw nyob
Lawv ua hauj lwm raws li ib tug txhim khu kev qha dej qhov chaw rau cov hluav taws kub cav thiab phau ntawv qhia kev tua hluav taws.
6. Kev xav txog kev teeb tsa
Kev txhim kho kom zoo yog qhov tseem ceeb kom ntseeg tau tias kev ua haujlwm ntawm hydrant:
Muab tso rau ntawm qhov chaw nkag tau raws txoj kev
Qhov chaw txaus (feem ntau yog 100-200 meters nyob ntawm txoj cai)
Kev tso dej kom zoo rau cov kav dej qhuav
Kev tiv thaiv lub tsheb cuam tshuam (piv txwv li, bollards)
7. Kev tu thiab tshuaj xyuas
Kev saib xyuas niaj hnub ua kom muaj kev ntseeg siab ua haujlwm:
Periodic tshuaj xyuas rau cov dej xau thiab corrosion
Kev sim ua haujlwm (qhib / kaw haujlwm)
Flushing kom tshem tawm cov khib nyiab
Lubrication ntawm txav qhov chaw
Kev txheeb xyuas ntawm qhov hluav taws xob threads thiab lub kaus mom
8. Cov lus xaus
Hluav taws kub hydrants ua lub luag haujlwm tseem ceeb hauv kev nyab xeeb hluav taws. Lawv tsim, xaiv, installation, thiab txij nkawm ncaj qha cuam tshuam rau kev tua hluav taws thiab kev nyab xeeb rau pej xeem. Kev nkag siab txog ntau hom, qauv, thiab cov kev xav tau ntawm kev ua haujlwm yog qhov tseem ceeb rau cov engineers, cov neeg cog lus, thiab cov kws tshaj lij tiv thaiv hluav taws.
