Breech Inlet vs qhuav riser
Kev nyab xeeb hluav taws xob hauv cov tuam tsev kev sib haum xeeb ntawm cov tshuab tsim tau tsim kom xa cov dej sai sai thiab muaj kev kub ntxhov sai sai. Ob qho kev sib xyaw ua ke ntawm cov kab ke noBreeching InketsthiabCov riswm qhuav, txhua tus muab cov haujlwm sib txawv hauv cov haujlwm tua hluav taws. Cov lus qhia no tshawb txog lawv qhov sib txawv, kev siv, thiab lawv ua haujlwm li cas ua ke rau kev nyab xeeb hauv tsev.
Breech Inlet (Hluav Taws Kub Department)
Ib qho kev pabcuam hluav taws (tseem hu ua kev pabcuam tua hluav taws Nws ua raws li lub rooj vag ntawm cov dej sib xyaw ua ke, xws li cov tshuab hluav taws lossis cov dej, kom txhawb nqa lub tsev uas muaj cov dej muaj tam sim no.
Cov hauj lwm tseem ceeb:
- Ua rau cov dej txhawb nqa kom sai / ntws thaum hluav taws kub loj.
- Muab kev nkag mus rau qhov siab -} Rose vaj tse 'standpipes lossis sprinkler tshuab.
- Tiv thaiv backflow ntawm cov kev kuaj xyuas cov khoom qub.
Qhuav riser
Ib lub tshuab hluav taws xob qhuav yog ib qho txheej txheem ntsug tawm hauv multi- zaj dab neeg rau faib dej hauv av-} qib mus rau sab saud. Tsis zoo li ntub dej ntws (uas tau ntim nrog dej), cov risers kom qhuav nyob tas mus kom txog thaum ua haujlwm, uas nias lawv siv cov dej lossis cov dej sab nraud.
Cov hauj lwm tseem ceeb:
- Pab txhawb nqa dej rau hauv cov tsev siab dua 18 meters (60 ko taw).
- Txo kev cia siab rau ntawm cov tso dej hauv dej sab hauv lossis cov ntiajteb txawj nqus {{}} free tshuab.
- Ua kom cov dej nce mus txog cov khoom siv hluav taws ntawm cov plag tsev ntau dua.
Breeching Inlet
Qho chaw: Nrig rau ntawm lub tsev sab nrauv sab nrauv, ib txwm nyob ze hauv av.
Cheebtsam:
- Inlet lub cev nrog cov couplings (piv txwv li, cov dab neeg lossis xov).
- Kos Valve kom tiv thaiv backflow.
- Siab Tag Huv Cua Heev Thiab Flow Tswj Valve Valve.
Khoom: Corrosion -} tiv taus hlau lossis tooj dag.
Lub peev xwm: Txhawb 2-4 Hose Kev sib txuas ib txhij (piv txwv li, 4-txoj inlets rau vaj tse loj).
Qhuav riser
Qho chaw: Khiav ntsug los ntawm stairwells lossis kev pabcuam shafts, nrog cov hluav taws xob rau hauv txhua lub tsev.
Cheebtsam:
- Ntsug lub ntsiab yeeb nkab (feem ntau 65-100 mm inch).
- Tsaws cov li qub (tawm) rau hauv ib lub tsev.
- Lub Valve Cua rau saum toj kom tso tawm cov cua nyob rau thaum cov khoom siv.
Khoom: Galvanized steel lossis stainless hlau.
Lub peev xwm: Tsim los lis kev ua kom zoo txog12 bar (174 psi)Rau siab -} nce kev siv.
Breeching Inlet
- Cov neeg tua hluav taws muab cov hoses rau lub inlet's couplings.
- Dej tab tom tso tawm los ntawm cov hluav taws tawg lossis cov menyuam dej rau hauv cov inlet.
- Tus check valve kom cov dej ntws rau hauv lub tsev lub tsev.
- Cov dej tso tawm kom nce mus txog Sprinklers, Stalpipes, lossis hose reels.
Qhuav riser
- Cov neeg tua hluav taws txuas hoses rau hauv av -}} qib breeching inlet (yog lub tsev muaj ib qho).
- Dej tau tso rau hauv cov riser qhuav, sau cov yeeb nkab ntsug.
- Cov neeg tua hluav taws qhib tsaws li qub ntawm cov plag tsev yuav tsum nkag mus rau cov dej.
- Dej ntws los ntawm hoses lossis sawv ntsug los tawm tsam hluav taws.
4. Kev thov thiab siv cov ntaub ntawv
Thaum twg siv cov inlet beeching
- High -} Rose vaj tse: Txhawm rau ntxiv cov dej sab hauv lub sijhawm hluav taws kub loj.
- Cov Chaw Muaj Cov Vaj Tse: Qhov twg hluav taws kub nyhav tshaj tus qauv muaj peev xwm kis tau.
- Thaj chaw uas tsis muaj kev tiv thaiv: Txhawm rau kom txaus txaus los ntawm cov tshuab hluav taws.
Thaum twg siv cov riser qhuav
- Vaj tse tshaj 18 metres siab: Yuav tsum tau los ntawm cov kab hluav taws hauv hluav taws hauv cov cheeb tsam.
- Multi - Zaj Dab Neeg Nyob / Cov Lag Luam Ua Lag Luam: Txhawm rau muab cov dej muaj kev sib npaug ntawm cov plag tsev.
- Cov qauv tsis muaj sia ntub: Qhov twg mus tas li dej cia yog impractical.
