Ductile hlau yeeb nkab fittings yog cov yeeb nkab fittings tsim los ntawm kev kho magnesium los yog tsawg lub ntiaj teb magnesium nrog kub spheroidizing neeg sawv cev. Lawv feem ntau siv cov khoom siv yeeb nkab hauv cov dej xa dej, cov kav dej, thiab cov kav dej phwj hauv kev lag luam.
Tsim los ntawm cov kav dej centrifugal ductile hlau thiab cov khoom sib txuam, cov khoom siv hauv nroog tau siv dav hauv cov dej thiab cov kav dej, cua sov, kev txuag dej thiab kev sib koom ua ke ntawm cov yeeb nkab gallery teb [2] [5]. Nws txais cov txheej txheem centrifugal casting, thiab tau txais cov qauv metallographic tom qab kho annealing. Nrog zinc txau, cement mortar los yog aluminate cement hauv ob sab phlu los txhim kho kev tiv thaiv kev tiv thaiv -corrosion kev ua tau zoo, sealing txheej tuaj yeem txo cov dej tsis kam, thiab kev sib koom ua ke yooj yim txhim kho seismic resistance thiab installation yooj yim [3-5].
Kev tsim qauv tsim
Qhov faus qhov tob ntawm cov kav xa dej yuav tsum tau txiav txim siab raws li cov xwm txheej xws li cov dej khov, cov khoom siv sab nraud, thiab kev sib tshuam nrog lwm cov kav dej. Nyob rau hauv ib txwm muaj xwm txheej, qhov faus qhov tob tuaj yeem yog 0.2 meters hauv qab kab te, thiab yuav tsum ua tau raws li cov xwm txheej hauv qab no: thaum cov yeeb nkab txoj kab uas hla ntau dua 100 hli, qhov tsawg kawg nkaus faus qhov tob ntawm cov yeeb nkab yog 1.20 meters.
Cov qauv tsim trench hauv qab dav yog feem ntau cov kab uas hla ntawm cov yeeb nkab ntxiv rau 0.5 meters, thiab txoj kab nqes excavation yog txiav txim siab raws li cov av. (i) Cov kav dej kav hlau yog tib yam li lwm cov kav dej. Lub taub hau poob raws txoj kev ntws ntawm cov dej tsis sib xws yog hf=λ/dv2/2g. Qhov sib txawv tsuas yog "λ" (hydraulic sib txhuam coefficient), uas yog, lub taub hau poob tuaj yeem suav tau raws li qhov kev tiv thaiv hauv zos poob ntawm thawj cov yeeb nkab hlau.
Qhov tshwm sim ntawm cov kav dej hlau tau muab rau kuv lub teb chaws txoj kev lag luam dej muaj kev ua tau zoo ntawm -kev ua tau zoo ntawm cov yeeb nkab tshiab. Txhawm rau kom siv cov kav dej zoo dua hauv cov haujlwm engineering, cov neeg tsim qauv thiab cov neeg ua haujlwm tsim kho yuav tsum paub txog lawv cov yam ntxwv, txuas ntxiv txheeb xyuas thiab daws cov teeb meem, tsim cov qauv tsim kom muaj txiaj ntsig thiab kev tsim kho ntau dua, kom cov khoom siv yeeb nkab tshiab no tuaj yeem ua lub luag haujlwm ntau dua hauv cov dej num.
Cov kev xav tau ntawm kev ua haujlwm
Nto zoo
Txheej
Sab hauv thiab sab nrauv ntawm cov yeeb nkab hlau fittings tuaj yeem coated nrog asphalt lossis lwm yam khoom siv los tiv thaiv -corrosion. Yog tias muaj cov cai tshwj xeeb, lawv yuav tsum tau txiav txim siab los ntawm kev sib tham ntawm tus neeg muag khoom thiab tus neeg yuav khoom.
Thaum cov yeeb nkab hlau fittings siv rau hauv av, cov kev huv huv yuav tsum ua raws li cov cai ntawm lub chaw saib xyuas kev noj qab haus huv.
Ua ntej txheej txheej, sab hauv thiab sab nraud ntawm cov yeeb nkab fittings yuav tsum tau ntxuav. Tom qab txheej txheej, sab hauv thiab sab nrauv yuav tsum du, thiab txheej txheej yuav tsum zoo ib yam, ruaj, thiab tsis txawv txav vim kev hloov pauv huab cua.
Main hom thiab specifications
Cov hom tseem ceeb ntawm cov yeeb nkab hlau fittings muaj xws li lub luj tshib, tees, crosses thiab flanges, ntawm cov luj tshib muaj ntau lub kaum ntse ntse xws li 90 degrees, 45 degrees, 22.5 degrees thiab 11.25 degrees ob chav -socket lub luj tshib, ob chav - flange lub luj tshib }}}.foot{{6}. Cov ntaub ntawv interface muaj ntau haiv neeg, suav nrog T hom, K hom, N hom, MJ hom, flange interface thiab socket interface xws li Tyton Joint [9] [12]. Cov kev ntsuas siab npog PN10, PN16, PN25 thiab PN40, thiab lwm yam. Cov yeeb nkab txoj kab uas hla ntawm DN80 txog DN3000 [6-7] [9]. Cov txheej txheej muaj xws li asphalt txheej thiab zinc nplua nuj epoxy txheej (FBE), thiab lwm yam. Cov khoom ua raws li cov qauv thoob ntiaj teb xws li ISO2531, EN545 thiab EN598 [9].
Application thiab Installation
Cov yeeb nkab hlau fittings yog dav siv nyob rau hauv kev sib raug zoo dej thiab cov kav dej, cov roj thiab cov kav dej, thiab lwm yam. [8].
Thawj kauj ruam hauv kev txhim kho cov hlau yeeb nkab fittings yog trench excavation. Lub hauv paus ntawm lub raj xa dej yuav tsum ua tau raws li cov qauv tsim. Yog tias lub zog ntawm lub hauv paus ntuj tsim ntawm cov kav dej tsis tuaj yeem ua tau raws li cov qauv tsim, nws yuav tsum tau ntxiv dag zog raws li cov qauv tsim. Thawj lub hauv paus av nyob hauv qab ntawm lub trench yuav tsum tsis txhob cuam tshuam. Thaum excavating mechanically, 200-300mm av txheej yuav tsum tau tshwj tseg nyob rau hauv qab ntawm lub trench rau phau ntawv excavation mus rau qhov tsim tsa thiab theem. Hauv qab ntawm lub trench yuav tsum tsis txhob ntub dej los yog khov. Yog hais tias hauv qab ntawm lub trench yog cuam tshuam los yog soaked nyob rau hauv dej, nws yog advisable kom rov qab ntim nrog gravel los yog txiv qaub av. Lub qhov (socket) yuav tsum tau sab laug rau lub qhov (socket) ntawm cov yeeb nkab ntawm txhua qhov sib koom ua ke kom ntseeg tau tias cov kav dej ncaj nraim thiab ua tau raws li qhov xav tau ntawm kev teeb tsa kev ua haujlwm. Lub qhov (socket) yuav tsum tau khawb raws li qhov tseeb qhov chaw ntawm lub qhov (socket) tom qab lub kav dej yuav tsum tau nteg tawm [10].
Kev npaj tsim kho
Cov hauv qab no yog cov kev npaj ua ntej txhim kho cov yeeb nkab hlau yeeb nkab fittings:
I. Ua kom tiav txhua yam ntawm lub hauv paus engineering tsim, thiab ib txhij ua tiav cov haujlwm hauv qab no:
Cov kab tswj lub hauv paus thiab lub hauv paus hauv qab cov kab nce siab tau raug cim.
Composite foundations thiab pawg hauv paus tau dhau qhov kev sim los ntawm chav kuaj;
Txoj kev npaj kho mob hauv paus yuav tsum tau pom zoo.
Tom qab lub hauv paus ua haujlwm tiav, chav tsev tsim kho tau tshuaj xyuas qhov zoo ntawm qhov project thiab paub tseeb tias qhov zoo ntawm qhov project ua tau raws li cov kev cai, cov kev cai thiab cov qauv tsim nyog rau kev tsim kho, nrog rau cov kev xav tau ntawm cov ntaub ntawv tsim. Lub tsev tsim kho tau xa daim ntawv tshaj tawm kev tsim kho (lub hauv paus) uas tau tshuaj xyuas thiab kos npe los ntawm tus thawj tswj hwm qhov project thiab cov neeg muaj feem cuam tshuam ntawm chav tsev tsim kho.
Nws tau ua tiav cov ntaub ntawv pov thawj thiab cov ntaub ntawv tswj kev tsim kho, thiab ua tau raws li cov ntaub ntawv khaws cia zoo ntawm Tianjin Municipal Construction Engineering Quality Supervision and Management Station;
Lub chaw saib xyuas tau ua qhov kev ntsuam xyuas zoo ntawm lub hauv paus engineering, muaj cov ntaub ntawv saib xyuas tiav, thiab xa daim ntawv qhia txog Tianjin Municipal Construction Engineering Foundation Txais Kev Saib Xyuas thiab Kev Ntsuam Xyuas, uas tau tshuaj xyuas thiab kos npe los ntawm tus thawj saib xyuas engineer thiab cov neeg muaj feem cuam tshuam ntawm chav saib xyuas.
Tag nrho cov teeb meem tau txiav txim kom raug kho los ntawm Lub Tsev Haujlwm Saib Xyuas Kev Npaj thiab Kev Tsim Kho Vaj Tse thiab nws qhov chaw tso cai hauv Cheeb Tsam Kev Tsim Kho Kev Tswj Xyuas Kev Tswj Xyuas Zoo tau raug kho.
Cov chaw soj ntsuam thiab tsim qauv tau tshuaj xyuas cov ntawv soj ntsuam thiab tsim cov ntaub ntawv thiab cov ntawv ceeb toom hloov pauv uas tau kos npe los ntawm cov qauv tsim thaum lub sijhawm tsim kho, thiab xa cov ntaub ntawv tshuaj ntsuam xyuas zoo uas tau tshuaj xyuas thiab kos npe los ntawm tus neeg saib xyuas ntawm qhov project ntsuam xyuas thiab tsim qauv thiab cov neeg muaj feem cuam tshuam los ntawm cov chaw soj ntsuam thiab tsim qauv, nrog rau cov ntawv tshaj tawm kev tshuaj xyuas zoo los ntawm lub chaw soj ntsuam thiab chav tsim qauv.
