Hauv kev tiv thaiv hluav taws niaj hnub thiab HVAC systems, kev saib xyuas dej txav yog qhov tseem ceeb rau kev nyab xeeb thiab kev ua haujlwm zoo. Txawm tias muaj ntau lub keyboards zoo sib xws, lawv ua haujlwm ntawm cov txheej txheem sib txawv thiab ua haujlwm tshwj xeeb. Phau ntawv qhia no tshawb txog qhov sib txawv ntawm Vane Type Water Flow Switch, Paddle Water Flow Switch, thiab Valve Supervisory Switch (feem ntau hu ua Valve Supervisory Switch).
■ Vane Hom Dej Flow Hloov
Cov【Vane Hom Dej Flow Hloov】yog cov cuab yeej siv ntau tshaj plaws siv hauv cov tshuab hluav taws xob tsis siv neeg. Nws txoj haujlwm tseem ceeb yog txhawm rau txheeb xyuas thaum lub taub hau lub taub dej tau qhib thiab dej ntws los ntawm cov kav dej.
Nws ua haujlwm li cas
Qhov kev hloov no muaj cov yas hloov tau yooj yim lossis hlau vane (tus "paddle") uas zaum hauv cov yeeb nkab, qhov perpendicular mus rau qhov ntws. Thaum dej txav ntawm tus nqi ntawm 10 nkas loos ib feeb (GPM) lossis ntau dua, nws thawb lub vane rau pem hauv ntej. Cov lus tsa suab no ua rau muaj kev sib txuas ua ke uas ua rau lub microswitch, xa cov teeb liab mus rau lub tswb hluav taws xob tswj vaj huam sib luag.
Cov yam ntxwv tseem ceeb
■ Lub Sijhawm Delay Mechanism:Feem ntau lub tshuab hluav taws xob muaj xws li pneumatic retard (ntev) feature, feem ntau kho tau los ntawm 0 txog 90 vib nas this. Qhov no tiv thaiv kev ceeb toom cuav tshwm sim los ntawm kev nce siab lossis "dej rauj."
■ Yeeb Nkab Mounting:Nws feem ntau yog ntsia rau sab nraud ntawm cov yeeb nkab. Ib lub qhov yog drilled rau hauv cov yeeb nkab, thiab lub vane yog ntxig. Nws ruaj ntseg siv U-bolt lossis eeb clamp.
■ Daim Ntawv Thov:Tsuas yog siv rau hauvntub- yeeb nkab sprinkler systems. Nws tsis tuaj yeem siv rau hauv qhuav- yeeb nkab lossis ua ntej- cov tshuab ua haujlwm vim tias qhov pib maj nrawm ntawm huab cua lossis dej tuaj yeem ua rau lub tshuab ua kom puas.
Paddle Water Flow Switch
Thaum cov ntsiab lus "vane" thiab "paddle" feem ntau siv sib hloov, hauv kev lag luam thiab HVAC cov ntsiab lus,【Paddle Water Flow Switch】hais txog ntau yam khoom siv, feem ntau me me siv rau kev saib xyuas cov kua dej es tsis yog kev tiv thaiv hluav taws xwb.
Nws ua haujlwm li cas
Zoo ib yam li hom vane, nws siv lub paddle kom nkag siab txog kev txav mus los. Txawm li cas los xij, paddle keyboards feem ntau yog tsim los rau cov yeeb nkab me me diameters (DN25) thiab nquag siv los saib xyuas cov dej ntws hauv chillers, kua - mus rau -kua kub exchangers, thiab twj tso kua mis.
Cov yam ntxwv tseem ceeb
■ Customizable Paddles:Ntau chav tuaj nrog ib txheej paddles ntawm qhov sib txawv ntev. Cov neeg siv tuaj yeem txiav cov paddle kom haum rau cov yeeb nkab tshwj xeeb thaum lub sijhawm teeb tsa.
■ rhiab heev:Cov no feem ntau rhiab ntau dua li hluav taws kub - ntsuas qhov hloov pauv thiab tuaj yeem siv los saib xyuas tus nqi qis hauv cov txheej txheem kev lag luam.
■ Xov txuas:Tsis zoo li U-bolt mounting ntawm hluav taws kub hloov, paddle keyboards feem ntau siv tus qauv NPT threaded kev twb kev txuas rau ntsia hlau ncaj qha rau hauv "T" haum rau hauv cov kav dej.
Valve Supervisory Hloov
Cov【Valve Supervisory Hloov】(feem ntau hu ua aTamper Hloov) ua hauj lwm rau lub hom phiaj sib txawv kiag li ntawm thawj ob. Thaum cov hloov pauv hloov pauvyog dej txav, tus saib xyuas hloov saib xyuasyog tias lub valve qhib.
Nws ua haujlwm li cas
Qhov kev hloov no yog mounted rau lub qia lossis tes ntawm lub valve (xws li npauj npaim valve, OS & Y rooj vag valve, lossis pob valve). Nws muaj lub caij nplooj ntoos hlav -loaded lever lossis plunger uas so tawm tsam lub valve. Yog tias ib tug neeg sim kaw lub valve kom kaw cov dej tawm, lub zog txav, txav mus rau qhov hloov pauv thiab xa cov teeb liab "saib xyuas" mus rau lub tswb.
Cov yam ntxwv tseem ceeb
■ Tamper Resistance:Cov keyboards no yog tsim los kom yooj yim rau bypass. Lawv xyuas kom meej tias cov dej tiv thaiv hluav taws yog ib txwm muaj.
■ Ob lub xeev:Nws feem ntau saib xyuas ob txoj haujlwm: "Fullly Open" lossis "Off-Normal."
■ Mounting Ntau yam:Nyob ntawm seb hom valve, koj tuaj yeem siv Potter Electric OSYSU rau lub rooj vag li qub lossis tshwj xeeb hauv cov keyboards rau npauj npaim li qub.

Koj xav tau ib qho twg?
Xaiv qhov kev hloov pauv yog nyob ntawm koj daim ntawv thov:
Yog tias koj tab tom txhim kho lub tshuab tua hluav taws:Koj xav tau covVane Hom Dej Flow Hloovkom ceeb toom rau lub tuam tsev tua hluav taws thaum lub taub hau qhib.
Yog tias koj tiv thaiv lub chiller lossis twj tso kua mis:Koj xav tau ibPaddle Water Flow Switchtxhawm rau xyuas kom cov cuab yeej tsis overheat lossis khiav qhuav yog tias lub twj tso kua mis tsis ua haujlwm.
Yog tias koj xav tau kom tau raws li qhov hluav taws kub code rau kev saib xyuas valve:Koj xav tau ibValve Supervisory Hloovtxhawm rau tiv thaiv kev kaw tsis raug cai - tawm ntawm koj cov dej.
Installation Cov kev coj ua zoo tshaj plaws
Kev taw qhia:Flow switches yuav tsum tau muab ntsia rau ntawm txoj kab ncaj nraim, yam tsawg kawg 6 mus rau 10 ntiv tes kom deb ntawm fittings los yog li qub kom tsis txhob muaj kev kub ntxhov.
Kev xaim:Nco ntsoov xa mus rau cov chaw tsim khoom cov kab kos duab. Rau cov tshuab hluav taws xob, xyuas kom lub qhov hluav taws xob tau txuas mus rau ib qho kev saib xyuas hluav taws xob yog li kev txiav hlau kuj ua rau muaj kev ceeb toom.
Kev sim:Cov dej ntws hloov pauv yuav tsum tau sim peb lub hlis twg los ntawm kev qhib qhov "Inspector's Test Connection" los simulate ib lub taub hau dej ntws.
