Lub tswb kos qhov chaw nyob qhov twg?

Lub tswb kos duab valve feem ntau yog ntsia hauvtxoj kev riser system, tus kav dej ntsug uas txuas rau cov dej hauv nroog lossis cov taub dej twj tso rau ntawm cov kais dej. Qhov chaw no kom tau saib xyuas nws cov neeg saib xyuas thiab tswj cov dej ntws mus rau tag nrho cov kab ke. Cov kev txiav txim siab tseem ceeb xws li:

• Qhov sib thooj rau cov dej xa: Cov Acv yog qhov chaw tam sim ntawd tam sim ntawd nqes dej ntawm cov dej dej (piv txwv, lub nroog tseem ceeb, hluav taws twj, lossis lub pob zeb nqus). Qhov no tso cai rau nws los txhawm rau txhawm rau hloov kho los ntawm cov kais tsuag dej thiab tiv thaiv rov qab mus rau hauv cov dej rau pej xeem.
• Kev nkag tau rau kev saib xyuas: Lub chaw yuav tsum tau nruab rau hauv thaj chaw muaj kev nkag mus, xws li chav tsev neeg kho tshuab, hluav taws chav tsev, lossis mob kais dej valve. Qhov no pab txhawb kev soj ntsuam, kev kuaj mob, thiab cov qauv kev tshuaj xyuas, kev kuaj xyuas, thiab kho cov dej {2} Raws li kev tiv thaiv hluav taws).
• Nce siab sab saud: Rau sab nraum zoov kev sib sau, ACV feem ntau muab tso rau hauv cov dej khov lossis dej nyab los tiv thaiv kom tiv thaiv khov. Nyob sab hauv tsev ib txwm nrhiav nws ze rau theem qab nthab lossis hauv cov pits tseg.

ACV lub chaw nyob yog ze khi rau nws lub tswb -} Nrhiav Cheebtsam. Cov no suav nrog:

• Lub cev muaj zog ceeb toom: Muab txoj hauj lwm nyob ib sab ntawm ACV, cov tshuab hluav taws xob ob lub tswb siv ntws ntws dej kom tig ib lub turbine thiab suab ib lub tswb. Lub valve bypass chaw nres nkoj ncaj qha txoj kev tswj hwm kom txaus rau lub tswb, ua kom pom tseeb cov lus ceeb toom thaum hluav taws.
• Siab: Ntsia rau ntawm lub system sab ntawm ACV, cov hluav taws xob cov ntsuas hluav taws xob pom cov tee thaum cov npuaj qhib. Lub pob hluav taws xob yog wired rau lub tsev hluav taws tswj vaj huam sib luag tswj vaj huam sib luag tswj, ua rau muaj tswb thiab cov ntawv ceeb toom.
• Flow Hloov: Mounted rau cov piping downstream ntawm ACV, cov khoom siv siv dej txav ntawm ib tug duav lossis vane. Lawv qhov chaw ua kom lawv ua kom lawv ua haujlwm tsuas yog thaum kais dej tawm, zam kev tsis tseeb ntawm lub siab surges.

NFPA 13 (tus qauv rau lub installation ntawm sprinkler cov cav) thiab cov hluav taws hluav taws hauv zos los tswj cov Acv Pleev:

• Ntub - yeeb nkaws tshuab: ACV yuav tsum tau nruab rau hauv lub ntsiab riser ntawm txhua qhov ntub - yeeb nkab system. Rau multi - zaj dab neeg vaj tse, txawv acvs tej zaum yuav tau rau txhua lub tsev sprinkler thaj chaw.
• Sib Sau Tshuab: Hauv kev sib xyaw qhuav - yeeb nkab / prev yog tso rau cov khoom siv deluge lossis huab cua tu khoom thiab tiv thaiv rov qab.
• High -} Rose vaj tse: ACVs feem ntau tau nruab rau ntawm cov ntsiab lus nruab nrab hauv cov qauv siab kom tau nyiaj rau kev hloov siab. Piv txwv li, lub tsev 50-zaj dab neeg yuav muaj acvs ntawm txhua 10 plag tsev.

a. Ib Leeg - Dab Neeg Kev Lag Luam Kev Lag Luam

Hauv cov tsev muag khoom, cov khw muag khoom muag, lossis ACV yog nyob ze ntawm lub tsev nkag hauv chav kho tshuab. Qhov kev tso chaw no ua kom muaj kev nkag tau yooj yim rau cov tua hluav taws kom tus kheej ua haujlwm ntawm lub valve yog tias xav tau.

b. Ntau - zaj dab neeg cov dab neeg thiab chaw ua hauj lwm

Rau siab -}}} sawv, ACVs tau muab ntsia rau hauv cov kav hlau ntsug rau ntawm txhua lub hauv qab lossis hauv nruab nrab cov tshuab hluav taws xob. Qhov no txo ​​qhov poob thiab ua kom pom tseeb sai sai.

c. Muaj cov khoom

Hauv cov chaw nyob nrog cov khoom puas tsuaj (piv txwv li cov nroj tsuag tsis zoo), acvs tau muab tso rau hauv qhov tawg {}}} Cov ntaub ntawv pov thawj nyob ze cov txheej txheem. Ntxiv rov qab los, xws li ob qho Acvs, tej zaum yuav tsum tau rau cov khoom tseem ceeb.

• Tswj Qhov Kub: ACVs yuav tsum tau muab ntsia rau hauv cov cheeb tsam uas kub nyob siab dua 40℃f (4 degree) los tiv thaiv khov. Nyob rau hauv huab cua txias, rhuab cov catform lossis tracw cua sov tshuab siv.
• Chaw Cuam Tshuam: Hauv cov vaj tse hauv nroog, ACVs yuav raug teeb tsa tav toj lossis hauv kev sib cav sib cav teeb tsa kom txuag tau qhov chaw.
• Suab nrov txo: Rau lub cev muaj zog lub tswb, ACV yog muab tso rau ntawm cov chaw nyob lossis nruab nrog lub suab nrov nrov.
