Tso lus
Hauv kev tiv thaiv hluav taws, covtswb check valveyog ib qho tseem ceeb tshaj plaws ntawm cov yeeb nkab ntub dej tua hluav taws kev teeb tsa. Nws ua hauj lwm ob lub hom phiaj: rautiv thaiv dej kom tsis txhob ntws rov qabnyob rau hauv qhov hluav taws kub department kev twb kev txuas los yog dej, thiab rauua rau lub tswb nrovthaum cov dej ntws mus rau hauv lub raj xa dej thaum muaj hluav taws kub.
Cov lus qhia no suav nrog txhua yam koj xav paub txog lub tswb ntsuas lub tswb, suav nrog lawv ua haujlwm li cas, lawv nyob qhov twg, yuav tsum muaj pes tsawg, cov khoom tseem ceeb, kev saib xyuas, thiab kev siv ntau yam.
Dab tsi yog Alarm Check Valve?
Lub tswb ntsuas valve yog ib qho tshwj xeebkos valvetsim tshwj xeeb rauntub-pipe hluav taws kub sprinkler systems.
Nws lub luag haujlwm tseem ceeb:
Cia dej ntwsmus rau sprinklersthaum ua kom tiav
Tiv thaiv kev thim rov qab mus rau hauv lub nroog cov dej los yog lub twj tua hluav taws
Qhib adej lub cev muaj zog tswb, hloov siab, lossis hluav taws xob tswbthaum dej ntws
Pab tswj astatic siab tshuav nyiaj li casnruab nrab ntawm cov khoom siv thiab sab system
Hauv luv luv: nws ua kom dej tsuas yog mus ib txoj kev -mus rau sprinklers- thiab ceeb toom koj thaum nws ua.
Lub tswb ntsuas valve ua haujlwm li cas?
Nyob rau hauv tej yam kev mob:
Lub valve tseem nyobkawvim qhov system static siab.
Dej siab tuav lub clapper nyob rau hauv qhov chaw, ua kom lub kaw lus pressurized tab sis tsis ntws.
Thaum hluav taws:
Ib los yog ntau dua cov dej ntws qhib, xa rov qab lub zog siab.
Kev siv lub siab thawb lub clapper qhib, cia dej ntws.
Cov dej ntws activates lubtswb chaw nres nkoj- txuas nrog lub siab hloov lossis dej lub cev muaj zog.
Lub tswb ceeb toom xa cov teeb liab mus rau qhov hluav taws kub tswj vaj huam sib luag los yog suab ceeb toom suab.
Lub check mechanism tiv thaiv dej los ntawm kev thim rov qab.
Yuav tsum muaj pes tsawg lub tswb ntsuas li qub nyob rau hauv qhov hluav taws kub Sprinkler System?
Tus naj npawb ntawm lub tswb ntsuas lub valve nyob ntawm qhov kev tsim qauv, qhov loj me, thiab qhov xav tau hydraulic:
General Rules of Thumb
Feem ntau cov qauv ntub-pipe systems: Ib lub tswb check valverau thaj chaw sprinkler.
Cov tsev loj, tsev siab siab, lossis thaj chaw tua hluav taws: Tej zaum yuav xav tauntau lub tswb ntsuas valve, ib qho rau txhua cheeb tsam hydraulic lossis sab sab nraud.
NFPA 13 (Standard for the Installation of Sprinkler Systems)xav kom txhua lub tshuab sprinkler muaj peev xwm ntawm lub suab tswb yuav nruab nrogtsawg kawg yog ib lub tswb kos valvelos yog sib npaug ntaus ntawv.
Cov kab ke uas muaj cov kav dej sib cais, kev ua ntej, lossis thaj chaw dej nyab yuav muaj lawv tus kheej li qub thiab tuaj yeem siv lub tswb sib txawv.
Hauv feem ntau ntawm kev lag luam thiab kev lag luam, koj yuav pomib lub tswb kos valve rau lub ntsiab sprinkler riser.
Cov Cheebtsam tseem ceeb ntawm lub tswb ntsuas Valve los ua ke
Lub tswb ntsuas valve muaj xws li:
Kuaj Valve Lub Cev: Cam khwb cia hlau los yog ductile hlau, nrog hinged clapper.
Tswb kab txuas: Chaw nres nkoj uas qhib lub tswb thaum muaj dej tshwm sim.
Siab Gauges: Supply side thiab system side pressure monitoring.
Test Drain: Siv rau kev ntsuas lub tswb muaj nuj nqi yam tsis muaj kev ua kom lub tshuab nqus dej.
Shutoff Valves: cais lub valve rau kev kho.
Tswb Devices:
Hloov siab (rau hluav taws xob tswb)
Dej lub cev muaj zog gong (mechanical audible tswb)
Retarding Chamber: Txo cov tswb cuav tshwm sim los ntawm kev kub ntxhov.
Tswb Check Valves Nyob qhov twg?
Tej qhov chaw:
Hauvhluav taws kub sprinkler riser chav
Nyob ze ntawm lub qhov dej nkag nkag
Nyob rau hauv lub hauv paus ntawm txhua cov yeeb nkab ntub dej sprinkler riser
Ua ntej lub ntsiab seem tswj valve
Lawv ib txwm ntsia rau hauv ib qhosiv tau qhov chawrau kev kuaj, tshuaj xyuas, thiab kho.
Hom Tswb Check Valves
Clapper-Type Alarm Check Valve
Feem ntau siv rau cov kav dej ntub dej
Yooj yim, txhim khu kev qha, tsis tshua muaj txij nkawm
Npauj Npaim-Style Tswb Check Valve
Siv hauv kev lag luam loj dua
Compact, qis siab poob
Vertical vs. Kab rov tav Installation
Feem ntau yog tsim rauntsuginstallation ntawm lub riser
Qee cov qauv tso cai rau kev teeb tsa kab rov tav (ib txwm ua raws cov chaw tsim khoom specs)
Vim li cas koj tsis tuaj yeem hla lub tswb ntsuas Valve
Tiv thaiv kev sib kis: Tiv thaiv cov dej haus los ntawm kev rov qab los.
Yuav tsum tau Code: NFPA 13 thiab feem ntau hauv zos cov cai tswj hwm nws.
Txo cov tswb cuav: Lub chamber retarding tiv thaiv lub tswb tsis tsim nyog los ntawm kev kub siab.
Muab Kev Tshawb Fawb: Paub meej tias cov dej ntws tiag tiag - tsis yog hloov siab xwb.
Kev tshuaj xyuas & Kev tu xyuas zoo tshaj plaws
Yuav kom lub valve ua haujlwm zoo:
Tshawb xyuas peb lub hlis twg rau kev xau, kev puas tsuaj, lossis corrosion.
Kuaj lub tswb muaj nuj nqitxhua xyoolos ntawm kev qhib qhov kev sim ntws.
Xyuas kom tseeb tias cov ntsuas ntsuas siab ua haujlwm.
Xyuas kom tsis txhob muaj lub valve raug kaw lossis kaw tsis raug cai.
Hloov cov gaskets, ntsaws ruaj ruaj, los yog clappers raws li xav tau.
