Txhim kho CPVC valve zoo li yooj yim, tab sis ib qho luv luv tuaj yeem ua rau muaj teeb meem loj. Kev sib koom ua ke tsis muaj zog tuaj yeem sib cais nyob rau hauv siab, ua rau muaj kev puas tsuaj loj hauv dej thiab ua haujlwm tsis zoo.
Txhawm rau txhim kho CPVC pob valve kom zoo, koj yuav tsum siv CPVC tshwj xeeb primer thiab hnyav cement. Cov txheej txheem cuam tshuam nrog kev txiav cov yeeb nkab square, deburring ntawm ntug, priming ob qhov chaw, thov cov cement, thiab tom qab ntawd thawb thiab tuav cov kev sib koom ua ke kom tso cai rau cov tshuaj weld tsim.
Cov txheej txheem no yog hais txog chemistry, tsis yog kua nplaum xwb. Txhua kauj ruam yog qhov tseem ceeb los tsim kom muaj kev sib koom ua ke uas muaj zog npaum li cov yeeb nkab nws tus kheej. Nov yog qee yam uas kuv ib txwm ntxhov siab thaum tham nrog kuv cov neeg koom tes, xws li Budi, tus thawj tswj kev yuav khoom hauv Indonesia. Nws cov neeg siv khoom feem ntau ua haujlwmdej kub systemsrau tsev so lossis chaw ua haujlwm. Nyob rau hauv cov cheeb tsam ntawd, kev sib txuas ua tsis tau tsuas yog xau; nws yog ateeb meem kev nyab xeeb loj. Cia peb rhuav tshem cov lus nug tseem ceeb kom paub tseeb tias koj lub installation muaj kev nyab xeeb, ruaj ntseg, thiab ua kom ntev.
Koj txuas lub valve rau CPVC li cas?
Koj muaj koj lub valve thiab cov yeeb nkab npaj mus. Tab sis kev siv cov txheej txheem tsis raug lossis cov khoom siv yuav tsim kom muaj kev sib cog lus tsis muaj zog uas yuav luag lav tias yuav ua tsis tau raws sijhawm.
Thawj txoj hauv kev rau kev txuas lub valve rau CPVC yeeb nkab yog hnyav vuam. Qhov no siv ib qho tshwj xeeb CPVC primer thiab cov cement rau chemically yaj thiab fuse cov yas nto, tsim ib leeg, seamless, thiab ruaj khov-pov thawj sib koom ua ke.
Xav txoghnyav weldingraws li qhov tseeb tshuaj fusion, tsis yog lo ob yam ua ke. Lub primer pib los ntawm softening thiab ntxuav lub txheej txheej ntawm cov yeeb nkab thiab lub qhov (socket) ntawm lub valve. Ces, lubCPVC cement, uas yog kev sib xyaw ntawm cov kuab tshuaj thiab CPVC resin, ntxiv melts cov chaw no. Thaum koj thawb lawv ua ke, cov plastics melted ntws mus rau hauv ib leeg. Raws li cov kuab tshuaj evaporate, cov yas re-hardens rau hauv ib qho khoom. Qhov no yog vim li cas siv qhov tseeb, CPVC-txheej cement (feem ntau daj xim) yog tsis sib tham. Tsis tu ncua PVC cement yuav tsis ua haujlwm ntawm CPVC cov tshuaj pleev xim sib txawv, tshwj xeeb tshaj yog thaum kub kub. Thaum threaded kev twb kev txuas kuj yog ib qho kev xaiv, hnyav welding yog tus qauv rau ib tug yog vim li cas: nws tsim lub zog tshaj thiab txhim khu kev qha daim ntawv cog lus.
Puas yog CPVC tiag tiag tsis siv lawm?
Koj hnov ntau txog kev hloov pauv PEX tubing hauv kev tsim kho tshiab. Qhov no tuaj yeem ua rau koj xav tias CPVC yog cov khoom siv tsis tu ncua, thiab koj txhawj xeeb txog kev siv nws rau koj qhov project.
CPVC yeej tseem siv thiab yog qhov kev xaiv zoo tshaj plaws rau ntau daim ntawv thov. Nws yog qhov tshwj xeeb tshaj yog rau cov kab dej kub thiab hauv cov chaw lag luam vim nws qhov ntsuas kub siab, tshuaj lom neeg tsis kam, thiab rigidity ntev, ncaj khiav.
Lub tswv yim tiasCPVCyog obsolete yog ib qho misconception. Kev lag luam kav dej tau tsuas yog loj hlob kom suav nrog cov khoom siv tshwj xeeb.PEXyog qhov zoo heev rau nws qhov yooj yim, ua rau nws nrawm rau nruab rau hauv qhov chaw nruj nrog tsawg fittings. Txawm li cas los xij, CPVC muaj qhov zoo sib xws uas ua rau nws tseem ceeb. Kuv tham txog qhov no ntau zaus nrog Budi, uas nws lub lag luam Indonesian xav tau ntau heev rau nws. CPVC yog nruj dua, yog li nws tsis sag ntev ntev thiab zoo li zoo dua hauv kev teeb tsa. Nws kuj tseem muaj qhov ntsuas qhov ntsuas kub txog li 200 ° F (93 ° C), uas siab dua li feem ntau PEX. Qhov no ua rau nws nyiam cov khoom siv rau ntau daim ntawv thov dej kub lag luam thiab cov kab ua lag luam. Qhov kev xaiv tsis yog hais txog qub thiab tshiab; nws yog hais txog xaiv cov cuab yeej tsim nyog rau txoj haujlwm.
CPVC vs. PEX: Qhov txawv tseem ceeb
| Feature | CPVC (Chlorinated Polyvinyl Chloride) | PEX (Cross-linked Polyethylene) |
|---|---|---|
| Yooj yim | Riam | Yooj yim |
| Max kub | Siab (txog 200 ° F / 93 ° C) | Zoo (txog 180 ° F / 82 ° C) |
| Kev teeb tsa | Solvent Welding (kua nplaum) | Crimp / Clamp Rings lossis Expansion |
| Qhov zoo tshaj plaws siv Case | Kub & dej txias kab, ncaj khiav | Cov kav dej hauv tsev, hauv-joist khiav |
| UV Resistance | Tsis zoo (yuav tsum tau pleev xim rau sab nraum zoov) | Tsis zoo (yuav tsum tau tiv thaiv los ntawm tshav ntuj) |
Puas muaj teeb meem qhov twg lub pob valve raug teeb tsa?
Koj npaj tau mus tas li cement ib lub valve rau hauv cov kav dej. Tab sis yog tias koj nruab nws rov qab, koj tuaj yeem yuam kev thaiv qhov tseem ceeb lossis ua kom rov qab kho tsis tau.
Rau tus qauv tseeb union pob valve, qhov kev taw qhia ntws tsis cuam tshuam rau nws lub peev xwm kaw. Txawm li cas los xij, nws yog ib qho tseem ceeb rau nruab nws kom lub union ceev tau siv tau, tso cai rau lub cev tseem ceeb raug tshem tawm rau kev pabcuam.
A pob valveyog ib qho ntawm qhov yooj yim thiab zoo tshaj plaws valve tsim. Lub pob foob tiv thaiv lub rooj zaum hauv qab, thiab nws ua haujlwm sib npaug zoo txawm tias cov dej ntws los ntawm txoj kev twg. Qhov no ua rau nws "bi-directional." Qhov no yog qhov txawv ntawm li qub xws li kos li qub lossis lub ntiaj teb li qub, uas muaj cov xub meej thiab yuav tsis ua haujlwm yog tias ntsia rov qab. Qhov tseem ceeb tshaj plaws "kev taw qhia" rau atiag union pob valvezoo li cov uas peb ua ntawm Pntek yog ib qho teeb meem ntawm kev siv tswv yim. Tag nrho cov ntsiab lus ntawm kev tsim lub koomhaum tiag tiag yog tias koj tuaj yeem tshem tawm cov koomhaum thiab nqa lub hauv paus ntawm lub valve tawm rau kev kho lossis hloov. Yog tias koj nruab lub valve dhau ze rau ntawm phab ntsa lossis lwm qhov haum qhov uas koj tsis tuaj yeem tig cov txiv ntoo hauv lub koomhaum, koj ua tiav nws qhov txiaj ntsig tseem ceeb.
Yuav ua li cas ua kom cov kua nplaum CPVC pob valve?
Koj nyob rau theem tseem ceeb tshaj plaws: ua qhov kev sib txuas zaum kawg. Ib daim ntawv thov sloppy ntawm cov cement tuaj yeem ua rau qeeb, zais drip lossis tam sim ntawd, kev puas tsuaj loj.
Txhawm rau ua tiav cov kua nplaum CPVC, koj yuav tsum ua raws li cov txheej txheem meej: txiav cov yeeb nkab, tshem tawm ntawm ntug, siv CPVC primer, coated ob qhov chaw nrog CPVC cement, thawb ua ke nrog peb lub hlis twg tig, thiab tuav nws ruaj khov rau 30 vib nas this.
Cia peb taug kev los ntawm kauj ruam dhau los no. Tau txais txoj cai no ua kom muaj kev sib koom ua ke zoo txhua lub sijhawm.
- Txiav & Ntxuav:Txiav koj cov yeeb nkab CPVC kom square li sai tau. Siv cov cuab yeej deburring lossis riam kom tshem tawm cov burrs ntawm sab hauv thiab sab nraud ntawm cov yeeb nkab ntug. Cov burrs no tuaj yeem nres cov yeeb nkab los ntawm kev zaum siab.
- Test Fit:Ua "qhuav haum" kom ntseeg tau tias cov yeeb nkab mus txog 1/3 txog 2/3 ntawm txoj kev mus rau hauv lub qhov (socket valve). Yog hais tias nws bottoms tawm yooj yim, lub haum yog xoob heev.
- Prime:Thov lub tsho tiv no ntawm liberalCPVC primer(feem ntau yog ntshav lossis txiv kab ntxwv) rau sab nraud ntawm cov yeeb nkab kawg thiab sab hauv ntawm lub qhov (socket) valve. Lub primer softens cov yas thiab yog ib qho tseem ceeb rau ib tug muaj zog weld.
- Cement:Thaum lub primer tseem ntub, thov ib txheej ntawm CPVC cement (feem ntau daj) hla cov cheeb tsam primed. Siv rau cov yeeb nkab ua ntej, ces lub qhov (socket).
- Sib dhos & tuav:Tam sim ntawd thawb cov yeeb nkab rau hauv lub qhov (socket) nrog lub quarter-tig. Tuav qhov sib koom ua ke kom ruaj khov rau hauv qhov chaw li 30 vib nas this kom tiv thaiv cov yeeb nkab tsis txhob thawb rov qab. Tso cai rau kev sib koom ua ke los kho tag nrho raws li cov neeg tsim khoom cement cov lus qhia ua ntej lub zog rau lub zog.
Xaus
Txhim kho kom raug aCPVC valvetxhais tau hais tias siv cov primer thiab cov cement, ua tib zoo npaj cov yeeb nkab, thiab ua raws li cov txheej txheem vuam vuam raws nraim. Qhov no tsim kev ruaj ntseg, ruaj khov, tsis muaj kev sib txuas.
