Kev sib tham txog kev siv cov teeb liab li qub rau hluav taws kub hydrant tswj li qub hauv cov tsev siab

Lus Cim: Cov lus pom zoo siab hauv tsev hluav taws kub hydrant tswj valve siv lub teeb liab valve sib tham
Ntsiab lus: high-rise tsev hluav taws kub hydrant tswj valve teeb liab valve
Raws li cov kev cai ntawm "Code for Fire Prevention Design of high-rise Civil Buildings", nyob rau hauv lub tsev hluav taws kub hydrant system, cov kav dej yuav tsum tau muab faib ua ob peb ** ntu, thiab lub valve yuav tsum tau pom tseeb qhib thiab kaw cov paib. Qhov no yog kom tus naj npawb ntawm cov hydrant standpipes tsis tsawg tshaj li ib qho thaum cov yeeb nkab tau txais kev pab.
Nrog rau txoj kev loj hlob ntawm niaj hnub architecture, lub tsev ntawm ntau yam pipelines rau zoo nkauj thov yuav tsum tau muab zais kom deb li deb li sai tau mus decorate, yog li ntawd, hydrant kav nyob rau hauv lub qab nthab, raj zoo, yog dav, tab sis qhov no yog ib qho teeb meem, uas yog lub tswj valve ntawm qhov qhib hluav taws hydrant yeeb nkab tsis tuaj yeem tau txais kev saib xyuas, ua rau hluav taws kub hnyiab tuaj yeem siv tau. Nov yog qee qhov piv txwv:
Txoj haujlwm ntawm "State Grid Control Center ntawm Ministry of Hluav Taws Xob" npog thaj tsam kev tsim kho ntawm ntau dua 50,000 square metres, nrog peb lub tsev hauv av thiab 27 plag tsev saum av. Lub tsev siab tshaj 110 meters. Nws yog ib lub tsev ntse ntse ua ke nrog cov lus txib ntau lawm thiab xa tawm, chaw ua haujlwm thiab lub rooj sib tham ua haujlwm, thiab nws cov qib siab ntawm automation tsis tshua muaj nyob hauv Suav teb. Nyob rau hauv kev tsim ntawm lub tshuab nqus dej tsis siv neeg, kuv siv cov teeb liab li qub nyob rau hauv pem hauv ntej ntawm tag nrho cov dej ntws ntsuas, yog li cov xwm txheej ntawm lub kaw lus tuaj yeem tshwm sim hauv qhov chaw tswj hluav taws, thiab cov teeb meem tuaj yeem pom ntawm qhov pom tseeb. Tsis tas li ntawd, kev tswj cov dej theem ntawm lub neej thiab kev tua hluav taws, thiab qhov pib thiab nres ntawm lub twj tso kua mis hluav taws kuj tseem saib xyuas kom tsim nyog. Tsuas yog kev tswj lub valve ntawm qhov hluav taws kub hydrant system raws li qhov tshwj xeeb ntawm lub valve zoo tib yam, nws muaj cov cim pom tseeb ntawm kev qhib thiab kaw, tab sis tsis tuaj yeem pom hauv qhov chaw tswj hluav taws, ntxiv rau, cov li qub no nyob hauv lub raj zoo. thiab qab nthab rau kev xav tau kev zoo nkauj, qhov zoo ntawm cov neeg ua haujlwm tam sim no tsis tuaj yeem ua kom ntseeg tau qhov system. Nyob rau hauv kev tiv thaiv hluav taws nyob rau hauv tus txheej txheem ntawm kev lees txais, txawm hais tias cov thawj coj ntawm lub ministry project lub hauv paus chaw ua hauj lwm, kev tsim kho thiab tsim chav tsev yog heev tiag tiag, tau ua rau lub deployment thiab lub thaum ntxov rectification, zoo rehearsed, tab sis nyob rau hauv tus txheej txheem ntawm hluav taws kub official lub sij hawm. kev lees txais, tab sis muaj ib qho teeb meem, muaj hluav taws kub hydrant hluav taws kub hydrant ntawm lub standpipe txawm li cas los kuj tso tsis tau tawm ntawm cov dej, thiab lwm yam plaub yog ib txwm, Peb nrhiav tsis tau ib qho teeb meem ntawm lub chaw tswj hluav taws. Tom qab kev tshuaj xyuas, nws tau pom tias cov tswj valve ntawm ob qhov kawg ntawm lub riser raug kaw vim yog kev saib xyuas, thiab cov neeg ua haujlwm tsis qhib lub valve tom qab kev kho, ua rau cov hluav taws kub hnyiab tsis tau dej.
Kuv xav tias, nyob rau hauv cov ntaub ntawv uas txhua leej txhua tus muab qhov tseem ceeb heev rau, tseem tshwm sim zoo li cov teeb meem no, thiab feem ntau nyob rau hauv cov ntaub ntawv ntawm ib qho yooj yim tuag tes tuag taw ntau tsis paub yuav ua li cas cov teeb meem yuav tshwm sim. Qhov no muaj feem xyuam rau seb qhov hluav taws kub hydrant system yog tus yuam sij rau kev siv lub ntsiab lus ntawm cov teeb meem, thiab zam qhov teeb meem no tshwm sim * * txoj kev txhim khu kev qha yog qhov hluav taws kub hydrant system tswj li qub tau teeb tsa rau hauv lub teeb liab valve, thiab valve qhib los tso rau hauv qhov chaw. ntawm kev tswj hluav taws, kom cov neeg ua haujlwm tswj xyuas, txawm tias tus nqi tau nce, txawm li cas los xij, qhov piv ntawm kev nqis peev rau tag nrho cov hluav taws kub hydrant system tseem tsawg heev, thiab nws tuaj yeem ua rau tag nrho cov hluav taws kub hydrant system kev nyab xeeb ** kev txhim kho, uas Kuv xav tias tsim nyog rau kev nqis peev.
Tswj valve raws li kev faib tawm ntawm cov yam ntxwv nta (1) los ntawm ib leeg-lub rooj tswj valve: lub valve * * dav siv, muaj ib tug xau ib co  tso cai sib txawv siab ib co  complex flow thiab cov yam ntxwv ntawm cov qauv yooj yim, yog li tsim nyog rau lub nruj to taub, me me ua hauj lwm siab sib txawv ntawm huv nruab nrab, tab sis me me specifications ntawm lub valve nominal loj (DN (2) ncaj nraim los ntawm ob lub rooj tswj valve: nyob rau hauv sib piv rau lub ncaj los ntawm ib lub rooj tswj valve, nws muaj cov yam ntxwv ntawm loj to thiab loj tso siab sib txawv, yog li nws yog haum rau huv si media zaus nrog lax to yuav tsum thiab loj. ua hauj lwm siab sib txawv. Kev saib xyuas yuav tsum tau them rau seb qhov dej xau ntawm lub valve ua tau raws li cov txheej txheem tswj kev xav tau thaum xaiv lub valve.
(3) Lub tes tsho valve: lub tes tsho valve tau muab faib ua ib lub foob thiab muab ob npaug rau ob lub qauv, qhov qub zoo ib yam li ib lub rooj zaum valve, haum rau ib lub rooj zaum valve. Cov tom kawg zoo ib yam li ob lub rooj zaum valve, haum rau ob lub rooj zaum valve. Lub tes tsho valve kuj muaj cov yam ntxwv ntawm kev ruaj ntseg zoo, yooj yim thauj khoom thiab tshem tawm, tab sis tus nqi yog 50% ~ 200% siab dua li lub rooj zaum ib leeg, ob lub rooj zaum valve, kuj xav tau tshwj xeeb winding gasket. Lub tes tsho valve yog qhov qis tshaj plaws rau ib leeg - lub rooj zaum valve, ob lub rooj zaum valve daim ntawv thov ntawm lub valve.
(4) Lub kaum sab xis valve, throttle daim ntawv yog sib npaug rau ib lub rooj zaum valve, tab sis lub cev khiav yog yooj yim, muaj feem xyuam rau xau yuav tsum tau ib co  huv nruab nrab zaus thiab yuav tsum tau ntawm qhov sib txawv siab yog cov duab plaub.
(5) peb-txoj kev valve: nws muaj 3 txoj kev, tuaj yeem hloov ob lub rooj ncaj nraim valve, siv rau shunt thiab confluence thiab ob-theem ntws, qhov kub sib txawv tsis ntau tshaj 150 ℃. Thaum DN≤80 mm, confluence valve yuav siv tau rau shunt zaus.
(6) Diaphragm valve: yooj yim khiav txoj kev, diaphragm muaj qee yam kev ua haujlwm corrosion, haum rau nruab nrab tsis huv, tsis muaj zog corrosion nruab nrab ob ntu ntu.
Npauj npaim valve (7): nws yog qhov sib npaug rau kev siv ntu rau lub cev, thiab lub cev sib npaug ntawm lub rooj zaum dua, yog li "kev tu tus kheej" kev ua tau zoo, qee qhov  ntim hnyav. Haum rau qhov tsis huv nruab nrab thiab loj txoj kab uas hla, ntws loj, siab sib txawv. Thaum Dn> 300 hli, nws feem ntau ua tiav los ntawm npauj npaim valve.
(8) Pob valve: "O" hom pob valve thaum qhib tag nrho rau qhov qhib valve, "kev tu tus kheej" kev ua tau zoo dua, tsim nyog rau kev huv huv, fiber ntau nruab nrab ob lub sijhawm. "V" BALL valve muaj kwv yees li qhov sib npaug feem pua ​​​​ntawm cov yam ntxwv hloov kho, haum rau qhov tsis huv, muaj cov xov xwm fiber ntau, kho tau kuj loj tswj lub sijhawm. Pob li qub yog kim dua.
(9) Eccentric rotary valve: lub valve nruab nrab ntawm npauj npaim valve thiab pob valve, "kev tu tus kheej" kev ua tau zoo, kev tswj hwm kev ua haujlwm zoo, tuaj yeem txiav tawm, yog li nws tsim nyog rau qhov nruab nrab tsis huv, cov dej xau ntawm cov txheej txheem me me, tab sis tus nqi ntawm lub valve yog kim dua.
Thawj 6 ntawm cov khoom 9 no yog cov khoom siv hluav taws xob ncaj qha, thiab qhov kawg 3 yog angular stroke tswj li qub. Raws li daim ntawv thov ntawm lub valve tswj, nws yog ib qho tsim nyog yuav tsum tau ua kom pom tseeb lawv cov yam ntxwv thiab cov teeb meem xav tau kev saib xyuas. Txhua yam ntawm cov khoom sib txawv, cov khoom txhim kho tau hloov zuj zus nyob rau hauv 9 pawg ntawm cov khoom, nws yog ib qho yooj yim to taub 9 pawg ntawm cov khoom kom txawj siv lwm yam khoom.
