Breeching Inlet installation

Breeching Inlet Installation

Lub installation ntawm aBreeching Inlet(tseem hu ua aKev Pabcuam Hluav Taws Inlet, siavese txuas, lossisLub Chaw Haujlwm Hluav Taws Xob Txuas Txuas) yog qhov tseem ceeb tshaj plaws hauv kev tiv thaiv hluav taws. Tsim los pab txhawb kev sib txuas sai ntawm cov dej tawm sab nraud (xws li cov hluav taws kub tawg lossis cov qauv hluav taws xob sab hauv Cov lus qhia no muab cov kauj ruam -}}}}}} kev coj ua, thiab kev ua raws li kev nyab xeeb thiab kev ua tau zoo.

1. Lub Hom Phiaj thiab Tseem Ceeb ntawm Breeching Inlets

Breeching Inlets Ua rau kev tswj hwm kev nkag mus rau cov neeg tua hluav taws kom txhaj rau lub tsev tiv thaiv kev tiv thaiv hluav taws. Lawv yog qhov tseem ceeb hauv cov xwm txheej uas:

Lub tsev dej hauv sab hauv (piv txwv li, sprinklers lossis cov ris tsho qhuav) yog qhov tsis txaus vim tias siv hluav taws lossis siv hluav taws xob.
Qhov kev tso siab ntxiv lossis cov dej ntws yog qhov yuav tsum tau mus txog pem teb sab saud nyob rau hauv high - sawv txheej qauv.
Cov dej tseem ceeb tsis muaj lub siab txaus rau kev ua pa hluav taws.

Ib qho teeb tsa zoo breeching inlet ua kom sib xyaw nrog kev ua haujlwm nrog tua hluav taws, txo lub ntsiab lus teb thiab kev txhim kho hluav taws xob.

2. Ua ntej -} kev txiav txim siab

Ua ntej kev teeb tsa, ntau yam yuav tsum raug ntsuas kom ntseeg tau thiab ua haujlwm:

A. Kev tswj txoj cai

Cov Neeg Hluav Taws Hauv Zos: Ua raws li cov qauv hauv tebchaws thiab hauv zos, xws li:
NFPA 13 (US): Qhia rau cov tseev kom muaj rau cov tshuaj tsuag thiab hluav taws xob kev sib txuas.
En 671-3 (Teb chaws Europe): Qhia cov qauv qhia rau cov tshuab hluav taws kub tsau.
BS 9990 (UK): Muab cov lus qhia rau hluav taws rau cov tsev.
Lub tsev tso cai: Tau txais kev pom zoo tsim nyog los ntawm cov thawj coj hauv zej zog ua ntej kev teeb tsa.

B. Kev Ntsuas Xyuas Tsev

Qho chaw: Nruab cov inlet ntawm lub tsev sab nrauv, nyiam dua nyob ze ntawm qhov chaw nkag lossis hluav taws khiav tawm.
Tau yooj yim: Xyuas kom meej meej txog kev tshem tawm ntawm1 meter (3 taw)Nyob ib ncig ntawm cov inlet rau unobstructed tua tua hluav taws.
Pom tau: Khij lub inlet nrog reflective signage (piv txwv li, "tua hluav taws txuas") thiab pleev xim nws hauv qhov siab {2} eg, liab).

C. Tsim Qauv Tsim

Inlet hom: Xaiv nruab nrab2-txoj kev, 3-txoj kev, lossis 4-txoj kev couplingsRaws li lub tsev loj thiab hluav taws kev pheej hmoo. Cov vaj tse loj yuav xav tau ntau yam inlets.
YEEB NKAB SIZE: Siv cov kav dej nrog txoj kab uas hla ntawm tsawg kawg65 hli (2.5 nti)kom haum raws li high -} ndic ntws.
Siab Xav Tau: CIM ASiab -} txo lub valve (PRV)Yog tias lub tuam tsev cov kav dej tsis tuaj yeem tiv thaiv hauv lub nroog dej siab.

3. Kauj Ruam - -}} Ruam txheej txheem

Kauj ruam 1: Mounting lub inlet lub cev

Ruaj rau lub breeching inlet inlet inlet rau lub phab ntsa khov kho lossis mob siab mounting bracket siv stacket stacket siv stack steel bolts.
Nco ntsoov tias cov inlet yog qib thiab taw qhia kom yooj yim hose txuas (feem ntau 0.5th meter saum toj theem).

Kauj ruam 2: Txuas mus rau lub kaw hluav taws

Txuas cov inlet rau lub tsevQhuav riser(rau siab - sawv) lossisntub riserSiv galvanized steel lossis stainless hlau piping.
Nruab ibKos Valvenruab nrab ntawm cov inlet thiab riser los tiv thaiv backflow.
Siv cov pob qij txha flanged lossis welded sib txuas rau cov xau - eformation artlication.

Kauj ruam 3: Txhim kho couplings thiab li qub

Muab lo rautus ceevlossisXov Couplinglings(Raws li NFPA 1963 lossis BS 336) rau lub cev inlet.
Haum arooj vag valvelossisPob Pobnqes dej ntawm txoj kev co rau kev tuav tswj kev ntws tswj.
Ntxiv ibSiab Tag Ntsoovlos saib xyuas cov dej hauv dej siab.

Kauj Ruam 4: Cov tshev zaum kawg thiab kuaj

Tshawb xyuas txhua qhov sib txuas rau txeej, corrosion, lossis misalignment.
Ua ibHydrostatic Kev Ntsuam XyuasLos ntawm kev ntsuas cov kab ke rau 1.5 x cov kev ua haujlwm siab (rau NFPA 13).
Txheeb xyuas tias qhov inlet's check valve thiab prv (yog tias ntsia) muaj nuj nqi kom raug.

4. Post -}} Kev Tu

Kev Sawv Cev Ib txwm nquag xyuas kom ntev - sij hawm kev ntseeg tau:

Kev kuaj txhua hli: Kos rau cov khib nyiab, puas tsuaj, lossis thaiv kev.
Kev Xeem Ib Xyoo: Simuli cov hluav taws ua ke kom ntsuas tau ntws thiab siab.
Txheej txheem hloov: Hloov cov hlua khau hnav, li qub, lossis ntsaws ruaj txhua 5-10 xyoo.

5. Cov kev sib tw thiab cov kev daws teeb meem

Cav: Kev siv dej tsis txaus los ntawm cov chaw hauv nroog.

Lus teb: Nruab cov twj tso kua mis lossis cov roj loj dua - diam inlet.

Cav: Corrosion hauv ntug hiav txwv lossis dej noo noo.

Lus teb: Siv cov tubrog nkoj - qib steel stainless hlau los yog epoxy - coated piping.

Cav: Txheeb xyuas kev nkag tau vim kev npaj tsis zoo.

Lus teb: Tsiv hauv lub inlet thaum lub sij hawm rov qab thiab tswj cov cai tswjfwm nruj.
