Nyob rau hauv lub complex architecture ntawm kev tiv thaiv hluav taws niaj hnub thiab kev tswj cov kua dej, qhov kev hloov pauv (feem ntau hu ua tus ntsuas dej ntws) ua haujlwm tseem ceeb ntawm kev sib txuas ntawm cov kav dej thiab hluav taws xob tswb. Nws lub luag haujlwm yog kev dag ntxias yooj yim tab sis lub luag haujlwm tseem ceeb - tseem ceeb: txhawm rau txheeb xyuas qhov kev txav ntawm cov dej hauv cov kav dej thiab txhais qhov kev txav mus rau hauv lub teeb liab hluav taws xob.
Thaum muaj ntau yam thev naus laus zis muaj nyob -xws li ultrasonic, thermal, thiab magnetic flow meter- lub vane - hom ntws hloov tseem yog tus qauv kub rau ntub dej - yeeb nkab hluav taws kub sprinkler tshuab vim nws cov neeg kho tshuab resilience thiab ua tsis tau tiav - logic nyab xeeb.
Core Mechanism: Yuav Ua Li Cas
Kev ua haujlwm logic ntawm lub vane- hom ntws hloov chaw nyob ntawm qhov hloov tau yooj yim, ncig paddle (lub vane) uas zaum ncaj qha rau hauv txoj kev ntawm cov dej ntws.
Thaum lub kaw lus zoo li qub (tsis muaj dej txav), lub vane tseem nyob rau ntawm cov yeeb nkab. Txawm li cas los xij, thaum lub taub hau hluav taws tua hluav taws qhib los yog qhib lub valve, cov dej ntws tau thawb tawm tsam lub vane. Qhov kev txav no tsim ib qho kev siv tshuab ua haujlwm uas pivots lub qia mus ncig. Thaum cov dej ntws mus txog qhov pib tshwj xeeb-tus qauv thoob plaws hauv kev lag luam ntawm 4 mus rau 10 nkas loos ib feeb (GPM)-kab mus ncig ua rau muaj kev hloov pauv hauv lub thawv.
Anatomy ntawm High -Performance Flow Switch
Yuav kom nkag siab tias vim li cas qee qhov kev tsim ua lag luam ua lag luam, ib qho yuav tsum saib cov khoom sab hauv uas ua kom muaj kev ruaj khov thiab raug:
Lub Vane (Paddle):Niaj hnub nimno vanes feem ntau yog ua los ntawm cov khoom siv ruaj khov, hloov tau yooj yim uas tuaj yeem tiv taus siab - nrawm nrawm yam tsis muaj kev tawg. Lawv feem ntau yog tsim los nrog ib qho curvature kom ua kom muaj kev nkag siab zoo txawm tias tus nqi qis.
Retard Mechanism (Lub Sijhawm Ncua Sijhawm):Tej zaum qhov tseem ceeb tshaj plaws yog pneumatic retard. Cov tshuab dej ua rau "dej rauj" los yog siab surges. Yog tsis muaj ncua sij hawm, cov ripples tam sim no yuav ua rau lub tswb cuav. Kev hloov pauv siab - zoo tso cai rau kev ncua ncua sijhawm (feem ntau 0 txog 90 vib nas this), ua kom ntseeg tau tias tsuas yogtxhawb nqaflow- qhia txog qhov hluav taws kub tiag tiag- ua rau lub tswb.
Dual Switch Contacts:Sab saum toj-tier qauv muaj ob txheej ntawm Ib Tug Ncej Ob Chav Throw (SPDT) micro- hloov. Qhov no tso cai rau lub cuab yeej ua ob txoj haujlwm ib txhij: piv txwv li, ib qho kev sib cuag tuaj yeem ua rau lub tswb hluav taws hauv zos, thaum lwm tus xa cov teeb liab mus rau lub chaw saib xyuas hauv nruab nrab lossis lub tswb hluav taws xob tswj vaj huam sib luag.
Kev ntsuas siab:Kev lag luam- qib hloov pauv tau tsim los ua haujlwm hauv siab- qhov chaw siab, feem ntau ntsuas rau qhov siab tshaj plaws kev pabcuam siab ntawm 450 PSI, kom ntseeg tau tias lawv tsis xau lossis poob thaum lub sijhawm ntsuas kev ntsuas
Yuav tsum tau nruab
Qhov kev ntseeg siab ntawm kev hloov pauv yog hnyav heev nyob ntawm nws qhov chaw teeb tsa. Raws li kev lag luam Engineering Standards for Fire Protection, ob peb "Golden Rules" yuav tsum ua raws li:
1. Clearance los ntawm Turbulence:Txhawm rau tiv thaiv "sib tham" (lub vane bouncing vim muaj dej turbulent), qhov hloov yuav tsum tau nruab rau ntawm txoj kab ncaj nraim. Nws yuav tsum yog tsawg kawg yog 6 ntiv tes deb ntawm cov fittings uas hloov cov kev taw qhia ntawm ntws thiab yam tsawg kawg 24 ntiv tes deb ntawm tej li qub los yog ntws.
2. Kev taw qhia: Cov khoom siv no yog tsim los rau mounted rau saum cov yeeb nkab thaum ntsia kab rov tav. Qhov no tiv thaiv sediment los yog khib nyiab los ntawm kev nyob rau hauv lub mechanism, uas yuav ua rau lub vane lo.
3. Pipe Material Compatibility:Txawm hais tias lub kav dej yog Teem caij 10, Teem sijhawm 40, lossis txawm tias yas (CPVC), qhov hloov yuav tsum siv lub hauv paus mounting thiab gasket tshwj xeeb contoured rau cov yeeb nkab txoj kab uas hla sab nraud kom ntseeg tau tias lub foob tsis muaj dej.
Kev Kho thiab Kev Xeem
Ib qho kev hloov pauv yog ib qho "dormant" kev nyab xeeb; nws tuaj yeem zaum tsis ua haujlwm tau ntau xyoo ua ntej xav tau. Yog li ntawd, Kev Ntsuas Ntsuas Dej tsis tu ncua yog txoj cai lij choj thiab kev nyab xeeb.
Tus Kws Tshuaj Ntsuam Xyuas:Thaum lub sij hawm ib txwm sim, lub valve ntawm qhov kawg ntawm lub kaw lus tau qhib los simulate qhov ntws ntawm ib lub taub hau ib lub taub dej. Tus kws kho mob yuav siv sij hawm ntev npaum li cas rau qhov hloov mus qhib.
Kho qhov Retard:Yog tias lub tswb tshwm sim sai dhau (tshwj tsis yog) lossis siv sijhawm ntev (dhau li 90-thib ob qhov kev txwv kev nyab xeeb), tus kws tshaj lij kho lub pneumatic timer dial hauv tsev.
Kev tshuaj xyuas qhov muag:Nyob rau tib lub sijhawm, lub hau yuav tsum tau muab tshem tawm kom kuaj xyuas corrosion, xoob xaim, lossis cov cim qhia ntawm noo noo nkag. Ntau tus kws tshaj lij- qib hloov pauv siv cov huab cua tsis zoo, NEMA 4 cov ntawv pov thawj los tiv thaiv cov khoom siv hluav taws xob tsis zoo no.
Xaus
Qhov hloov pauv yog khawm "on-off" rau lub tsev teb thaum muaj xwm txheej ceev. Los ntawm qhov tseeb qhov txawv ntawm qhov tsis muaj kev kub ntxhov siab thiab lub neej - hluav taws kub, nws ua kom ntseeg tau tias kev pab tuaj txog raws nraim thaum xav tau yam tsis muaj kev cuam tshuam ntawm lub tswb cuav. Thaum xaiv qhov hloov pauv, tsom mus rau lub peev xwm siab, retard kev cia siab, thiab kev ruaj ntseg vaj tse yog qhov tseem ceeb rau txhua tus kws tshaj lij tiv thaiv hluav taws.
