Kev txhim kho lub valve CPVC zoo li yooj yim, tab sis ib qho luv luv me me tuaj yeem ua rau muaj teeb meem loj heev. Ib qho sib koom ua ke tsis muaj zog tuaj yeem tawg ua tej daim me me thaum muaj kev nyuaj siab, ua rau muaj kev puas tsuaj loj heev rau dej thiab ua haujlwm tsis muaj txiaj ntsig.
Yuav kom txhim kho lub pob valve CPVC kom raug, koj yuav tsum siv cov primer thiab cov cement solvent uas siv rau CPVC. Cov txheej txheem no suav nrog kev txiav lub yeeb nkab kom tiaj tus, tshem cov npoo, pleev xim rau ob qho chaw, siv cov cement, thiab tom qab ntawd thawb thiab tuav qhov sib txuas kom ruaj khov kom cov tshuaj sib txuas tau.
Cov txheej txheem no yog hais txog chemistry, tsis yog tsuas yog kua nplaum xwb. Txhua kauj ruam yog qhov tseem ceeb rau kev tsim kom muaj qhov sib koom ua ke uas muaj zog npaum li cov yeeb nkab nws tus kheej. Qhov no yog ib yam dab tsi uas kuv ib txwm hais txog thaum tham nrog kuv cov neeg koom tes, zoo li Budi, tus thawj tswj kev yuav khoom hauv Indonesia. Nws cov neeg siv khoom feem ntau ua haujlwm raucov tshuab dej kubrau cov tsev so lossis cov chaw tsim khoom lag luam. Hauv cov chaw ib puag ncig ntawd, kev sib txuas tsis ua haujlwm tsis yog qhov xau xwb; nws yog ib qhoteeb meem kev nyab xeeb loj heevCia peb muab cov lus nug tseem ceeb los xyuas kom meej tias koj qhov kev teeb tsa muaj kev nyab xeeb, ruaj ntseg, thiab ua kom ruaj khov.
Yuav ua li cas txuas lub valve rau CPVC?
Koj muaj koj lub valve thiab yeeb nkab npaj txhij lawm. Tab sis siv cov txheej txheem lossis cov khoom siv tsis raug yuav ua rau muaj kev sib txuas tsis muaj zog uas yuav luag lav tias yuav puas tsuaj raws sijhawm.
Txoj kev tseem ceeb rau kev txuas lub valve rau CPVC yeeb nkab yog kev vuam cov tshuaj yaj. Qhov no siv cov tshuaj CPVC primer thiab cement tshwj xeeb los yaj thiab sib xyaw cov yas, tsim kom muaj ib qho sib txuas, tsis muaj qhov sib txuas, thiab ruaj khov.
Xav txogkev vuam tshuajua ib qho kev sib xyaw ua ke tiag tiag, tsis yog tsuas yog lo ob yam ua ke xwb. Cov tshuaj primer pib los ntawm kev ua kom mos thiab ntxuav cov txheej sab nraud ntawm cov yeeb nkab thiab lub qhov (socket) sab hauv ntawm lub valve. Tom qab ntawd,CPVC cement, uas yog kev sib xyaw ntawm cov kuab tshuaj thiab CPVC resin, ntxiv yaj cov nto no. Thaum koj thawb lawv ua ke, cov yas yaj ntws mus rau hauv ib leeg. Thaum cov kuab tshuaj evaporate, cov yas rov khov kho rau hauv ib daim khov kho. Qhov no yog vim li cas siv cov cement CPVC kom raug (feem ntau yog xim daj) tsis tuaj yeem sib tham tau. Cov cement PVC ib txwm yuav tsis ua haujlwm ntawm CPVC cov tshuaj sib txawv, tshwj xeeb tshaj yog thaum kub siab. Thaum cov xov sib txuas kuj yog ib qho kev xaiv, kev vuam cov kuab tshuaj yog tus qauv rau ib qho laj thawj: nws tsim cov khoom sib txuas muaj zog tshaj plaws thiab txhim khu kev qha tshaj plaws.
Puas yog CPVC tsis siv lawm tiag?
Koj hnov ntau yam txog cov yeeb nkab PEX uas yoog tau hauv kev tsim kho tshiab. Qhov no yuav ua rau koj xav tias CPVC yog cov khoom siv qub dhau lawm, thiab koj txhawj txog kev siv nws rau koj qhov project.
CPVC yeej tseem siv tau thiab yog qhov kev xaiv zoo tshaj plaws rau ntau daim ntawv thov. Nws yog qhov tseem ceeb tshaj plaws rau cov kav dej kub thiab hauv cov chaw lag luam vim nws qhov ntsuas kub siab, tiv taus tshuaj lom neeg, thiab ruaj khov rau kev khiav ntev, ncaj.
Lub tswv yim hais tiasCPVCyog qhov tsis siv lawm yog ib qho kev nkag siab yuam kev. Kev lag luam plumbing tau loj hlob los suav nrog cov ntaub ntawv tshwj xeeb ntau dua.PEXzoo heev rau nws qhov kev ywj pheej, ua rau nws ceev nrooj rau kev teeb tsa hauv qhov chaw nqaim nrog tsawg dua cov khoom siv. Txawm li cas los xij, CPVC muaj cov txiaj ntsig sib txawv uas ua rau nws tseem ceeb. Kuv tham txog qhov no ntau zaus nrog Budi, uas nws lub khw Indonesian muaj kev xav tau loj heev rau nws. CPVC yog qhov ruaj khov dua, yog li nws tsis sag dhau lub sijhawm ntev thiab zoo li neater hauv kev teeb tsa raug. Nws kuj muaj qhov ntsuas kub ntawm kev pabcuam txog li 200 ° F (93 ° C), uas siab dua li feem ntau PEX. Qhov no ua rau nws yog cov khoom siv nyiam rau ntau daim ntawv thov dej kub lag luam thiab cov kab ua haujlwm hauv kev lag luam. Kev xaiv tsis yog hais txog qub vs. tshiab; nws yog hais txog kev xaiv cov cuab yeej zoo rau txoj haujlwm.
CPVC vs. PEX: Qhov Sib Txawv Tseem Ceeb
| Feature | CPVC (Chlorinated Polyvinyl Chloride) | PEX (Cross-linked Polyethylene) |
|---|---|---|
| Kev ywj pheej | Rigid | Yooj yim hloov pauv |
| Kub Tshaj Plaws | Kub heev (txog li 200°F / 93°C) | Zoo (txog li 180°F / 82°C) |
| Kev teeb tsa | Kev vuam cov kuab tshuaj (kua nplaum) | Crimp/Clamp Rings lossis Expansion |
| Cov Ntaub Ntawv Siv Zoo Tshaj Plaws | Cov kav dej kub thiab dej txias, khiav ncaj qha | Cov kav dej hauv tsev, cov kav dej hauv joist |
| Kev Tiv Thaiv UV | Tsis zoo (yuav tsum tau pleev xim rau kev siv sab nraum zoov) | Tsis zoo heev (yuav tsum tau tiv thaiv los ntawm lub hnub) |
Puas muaj teeb meem dab tsi uas lub pob dej tau teeb tsa?
Koj twb npaj txhij los txuas lub valve rau hauv cov kav dej tas mus li. Tab sis yog tias koj teeb nws rov qab, koj tuaj yeem thaiv qhov tseem ceeb lossis ua rau kev kho yav tom ntej tsis yooj yim sua.
Rau lub pob valve uas yog ib qho kev sib koom ua ke, qhov kev coj ntawm cov dej ntws tsis cuam tshuam rau nws lub peev xwm kaw. Txawm li cas los xij, nws yog ib qho tseem ceeb heev uas yuav tsum tau teeb tsa nws kom cov txiv ntoo sib koom ua ke nkag tau yooj yim, uas ua rau lub cev tseem ceeb raug tshem tawm rau kev pabcuam.
A lub pob valveyog ib qho ntawm cov qauv tsim valve yooj yim tshaj plaws thiab zoo tshaj plaws. Lub pob kaw tiv thaiv lub rooj zaum hauv qab, thiab nws ua haujlwm zoo ib yam tsis hais qhov twg dej ntws los ntawm. Qhov no ua rau nws "bi-directional." Qhov no txawv ntawm cov valve zoo li check valves lossis globe valves, uas muaj tus xub meej thiab yuav tsis ua haujlwm yog tias ntsia rov qab. Qhov "kev taw qhia" tseem ceeb tshaj plaws rau alub pob valve sib koom ua ke tiag tiagZoo li cov uas peb ua ntawm Pntek yog ib qho teeb meem ntawm kev nkag mus tau yooj yim. Lub ntsiab lus tseem ceeb ntawm kev tsim lub union tiag tiag yog tias koj tuaj yeem unscrew cov unions thiab tsa qhov nruab nrab ntawm lub valve tawm rau kev kho lossis hloov pauv. Yog tias koj teeb tsa lub valve ze dhau rau phab ntsa lossis lwm qhov chaw uas koj tsis tuaj yeem tig cov txiv ntoo union, koj ua rau nws qhov zoo tshaj plaws poob tag.
Yuav ua li cas koj thiaj li nplaum tau lub pob valve CPVC kom zoo?
Koj nyob rau theem tseem ceeb tshaj plaws: ua qhov kev sib txuas zaum kawg. Kev siv cov cement tsis zoo tuaj yeem ua rau qeeb qeeb, zais cia lossis ua tsis tiav sai sai.
Yuav kom nplaum tau lub qhov dej CPVC kom zoo, koj yuav tsum ua raws li cov txheej txheem kom meej: txiav lub yeeb nkab, tshem cov ntug, siv CPVC primer, pleev ob qho chaw nrog CPVC cement, thawb ua ke nrog ib feem plaub ntawm lub voj voog, thiab tuav nws kom ruaj rau 30 vib nas this.
Cia peb ua raws li cov kauj ruam no. Kev ua qhov no kom raug yuav ua rau muaj kev sib koom ua ke zoo meej txhua lub sijhawm.
- Txiav & Ntxuav:Txiav koj lub yeeb nkab CPVC kom ncaj li ncaj tau. Siv cov cuab yeej tshem cov burr lossis riam kom tshem tawm cov burrs ntawm sab hauv thiab sab nraud ntawm ntug yeeb nkab. Cov burrs no tuaj yeem tiv thaiv cov yeeb nkab kom tsis txhob zaum tag.
- Kev Ntsuas Qhov Haum:Ua ib qho "qhuav kom haum" kom ntseeg tau tias cov yeeb nkab mus txog li 1/3 txog 2/3 ntawm txoj kev mus rau hauv lub qhov (valve socket). Yog tias nws yooj yim tawm hauv qab, qhov haum ntawd xoob dhau lawm.
- Thawj:Thov ib lub tsho tiv no ntawmCPVC primer(feem ntau yog xim av lossis txiv kab ntxwv) rau sab nraud ntawm qhov kawg ntawm cov yeeb nkab thiab sab hauv ntawm lub qhov (valve socket). Cov tshuaj primer ua rau cov yas mos thiab yog qhov tseem ceeb rau kev vuam khov kho.
- Cement:Thaum cov tshuaj primer tseem ntub, thov ib txheej CPVC cement (feem ntau yog daj) sib npaug rau cov chaw uas tau primed. Thov rau ntawm cov yeeb nkab ua ntej, tom qab ntawd rau ntawm lub qhov (socket).
- Sib Dhos & Tuav:Tam sim ntawd thawb lub yeeb nkab mus rau hauv lub qhov (socket) nrog ib feem plaub tig. Tuav lub pob qij kom ruaj khov rau hauv qhov chaw li 30 vib nas this kom tiv thaiv lub yeeb nkab kom tsis txhob thawb rov qab. Cia lub pob qij kom qhuav tag raws li cov lus qhia ntawm cov chaw tsim khoom siv cement ua ntej nias lub tshuab.

Txhim kho kom raugCPVC lub qhov dejtxhais tau tias siv cov primer thiab cement kom raug, ua tib zoo npaj cov yeeb nkab, thiab ua raws li cov kauj ruam vuam cov kuab tshuaj kom raug. Qhov no tsim kom muaj kev sib txuas ruaj khov, ruaj khov, thiab tsis muaj qhov xau.
