Koj tau nplaum koj lub PVC valve tshiab rau hauv cov kav dej, tab sis tam sim no nws xau. Ib qho kev sib koom tsis zoo txhais tau tias koj yuav tsum tau txiav cov yeeb nkab thiab pib dua, nkim sijhawm thiab nyiaj txiag.
Txhawm rau nruab aPVC pob valve, koj yuav tsum siv PVC tshwj xeeb primer thiabhnyav cement. Cov txheej txheem suav nrog kev txiav cov yeeb nkab kom huv si, deburring, priming ob qhov chaw, thov cov cement, thiab tom qab ntawd thawb thiab tuav cov sib koom ua ke kom ruaj khov rau 30 vib nas this los tsim cov tshuaj lom neeg ruaj khov.
Cov txheej txheem no yog hais txog kev tsim cov tshuaj tiv thaiv uas muaj zog npaum li cov yeeb nkab nws tus kheej, tsis yog tsuas yog ua cov khoom sib txuas ua ke. Nws yog ib lub ntsiab lus tseem ceeb uas kuv ib txwm hais qhia rau kuv cov neeg koom tes, xws li Budi, tus thawj tswj kev yuav khoom hauv Indonesia. Nws cov neeg siv khoom, los ntawm cov neeg cog lus loj mus rau cov khw muag khoom hauv zos, tsis tuaj yeem them tsis taus. Ib qho kev sib koom ua ke tsis zoo tuaj yeem cuam tshuam qhov project ncua sij hawm thiab pob nyiaj siv. Cia peb taug kev los ntawm cov lus nug tseem ceeb kom ntseeg tau tias txhua qhov kev teeb tsa koj tau ua yog qhov ua tiav ntev.
Yuav ua li cas rau nruab ib lub pob valve ntawm PVC yeeb nkab?
Koj muaj qhov zoo, tab sis koj paub tias tsis muaj qhov thib ob nrog PVC cement. Ib qho yuam kev me me txhais tau hais tias txiav ib feem ntawm cov yeeb nkab thiab pib los ntawm kos.
Cov txheej txheem kev teeb tsa siv qhov hnyav vuam thiab suav nrog tsib kauj ruam tseem ceeb: txiav cov yeeb nkab square, tshem tawm cov npoo, siv PVC primer rau ob qho tib si, txheej nrog PVC cement, thiab tom qab ntawd thawb cov khoom ua ke nrog peb lub hlis twg tig thiab tuav lawv ruaj khov.
Tau txais cov txheej txheem no yog qhov cais txoj haujlwm tshaj lij los ntawm qhov teeb meem yav tom ntej. Cia peb tawg txhua kauj ruam hauv kev nthuav dav. Qhov no yog cov txheej txheem tseeb uas kuv muab rau Budi cov neeg siv khoom kom lav lub foob zoo meej.
- Txiav & Deburr:Pib nrog kev huv, square txiav ntawm koj cov yeeb nkab. Txhua lub kaum sab xis tuaj yeem tsim qhov sib txawv ntawm qhov sib koom ua ke. Tom qab txiav, siv cov cuab yeej deburring los yog rab riam yooj yim kom tshem tawm cov yas fuzz ntawm sab hauv thiab sab nraud ntawm cov yeeb nkab ntug. Cov burrs no tuaj yeem khawb cov cement tam sim ntawd thiab tiv thaiv cov yeeb nkab kom tsis txhob zaum tag nrho.
- Prime:Thov lub tsho tiv no ntawm liberalPVC primer(nws feem ntau yog ntshav) mus rau sab nraud ntawm cov yeeb nkab thiab sab hauv ntawm lub qhov (socket) valve. Tsis txhob hla cov kauj ruam no! Primer tsis yog ib qho tshuaj ntxuav xwb; nws pib soften cov yas, npaj nws rau cov tshuaj weld.
- Cement:Thaum lub primer tseem ntub, thov ib txheej txawm ntawmPVC cementtshaj thaj chaw primed. Thov nws mus rau cov yeeb nkab ua ntej, ces muab lub qhov (socket) lub qhov (socket) lub tsho nyias nyias.
- Push, Tig & Tuav:Tam sim ntawd thawb cov yeeb nkab mus rau hauv lub qhov (socket) nrog me me lub quarter-tig twist. Qhov kev sib tw no pab nthuav cov cement sib npaug. Tom qab ntawd koj yuav tsum tuav qhov sib koom ua ke kom ruaj khov rau yam tsawg 30 vib nas this. Cov tshuaj tiv thaiv ua rau lub siab uas yuav sim thawb cov yeeb nkab rov qab.
Yuav ua li cas yog txoj cai rau nruab ib lub pob valve?
Lub valve yog nyob rau hauv, tab sis tus kov hits phab ntsa. Los yog phem dua, koj tau teeb tsa lub koomhaum pabcuam tiag tiag kom ze rau lwm qhov haum uas koj tsis tuaj yeem tau txais lub ciaj ntswj ntawm cov txiv ntoo.
Qhov "txoj kev yog" rau nruab lub pob valve xav txog kev siv yav tom ntej. Qhov no txhais tau tias kom tus kov muaj tag nrho 90-degree clearance tig thiab tias lub union txiv ntseej ntawm ib tug tiag tiag union valve yog kiag li siv tau rau yav tom ntej tu.
Ib tug ua tiav installation yog hais txog ntau tshaj li ibleak-proof seal; nws yog hais txog kev ua haujlwm ntev. Qhov no yog qhov kev npaj me me ua rau muaj qhov sib txawv loj. Qhov yuam kev tshaj plaws uas kuv pom yog tsis muaj kev npaj rau kev nkag. Lub pob valve yuav tsum tig 90 degrees mus los ntawm qhov qhib siab kom kaw tag nrho. Ua ntej koj txawm qhib lub kaus poom ntawm cov cement, tuav lub valve nyob rau hauv qhov chaw thiab viav vias tus kov los ntawm nws cov lus tsa suab tag nrho. Xyuas kom nws tsis txhob tsoo phab ntsa, lwm cov yeeb nkab, lossis lwm yam. Qhov thib ob, tshwj xeeb tshaj yog rau peb Pntektiag union li qub, yog union access. Tag nrho cov txiaj ntsig ntawm kev tsim lub koomhaum tiag tiag yog tias koj tuaj yeem tshem tawm cov koomhaum thiab nqa lub cev tseem ceeb tawm rau kev kho lossis hloov yam tsis tau txiav cov yeeb nkab. Kuv ib txwm ceeb toom Budi kom ntxhov siab qhov no rau nws cov neeg ua haujlwm cog lus. Yog tias koj nruab lub valve qhov twg koj tsis tuaj yeem tau txais ib lub ciaj ntswj ntawm cov txiv ntseej, koj nyuam qhuav hloov tus nqi, kev pabcuam valve rau hauv tus qauv, pov tseg ib qho.
Yuav ua li cas txuas lub valve rau PVC yeeb nkab?
Koj lub valve muaj xov, tab sis koj cov yeeb nkab yog du. Koj tab tom xav yog tias koj yuav tsum muab cov nplaum, xov nws, lossis yog tias ib txoj hauv kev zoo dua li lwm qhov rau kev sib txuas zoo.
Muaj ob txoj hauv kev tseem ceeb: qhov hnyav vuam (gluing) rau kev ruaj khov, fused daim ntawv cog lus, thiab cov xov sib txuas rau kev sib koom ua ke uas tuaj yeem muab tshem tawm. Rau PVC-rau-PVC systems, hnyav welding yog txoj kev muaj zog thiab ntau dua.
Xaiv hom kev sib txuas zoo yog qhov tseem ceeb. Feem ntau ntawm PVC systems cia siab rauhnyav welding, thiab yog vim li cas. Nws tsis tsuas yog lo rau qhov chaw ua ke; nws chemically fuses lawv mus rau hauv ib leeg, seamless daim yas uas yog incredibly muaj zog thiab leak-proof. Cov xov sib txuas muaj lawv qhov chaw, tab sis lawv kuj muaj qhov tsis muaj zog. Lawv muaj txiaj ntsig zoo thaum txuas PVC valve rau lub twj tso kua mis hlau lossis lub tank uas twb muaj xov. Txawm li cas los xij, kev sib txuas ntawm cov yas threaded tuaj yeem yog qhov chaw xau yog tias tsis kaw zoo nrog Teflon daim kab xev lossis muab tshuaj txhuam. Qhov tseem ceeb tshaj, kev nruj ntawm threaded yas haum yog ib qho yuam kev uas tuaj yeem tawg cov poj niam kev sib txuas, ua rau tsis ua haujlwm.
Kev sib txuas txoj kev sib piv
| Feature | Solvent Weld (Qhov (socket)) | Xov xov (MPT/FPT) |
|---|---|---|
| Lub zog | Zoo heev (Fused Joint) | Qhov zoo (Potential weak point) |
| Kev ntseeg tau | Zoo heev | Kev Ncaj Ncees (Nyob rau ntau-tightening) |
| Kev siv zoo tshaj plaws | Kev sib txuas ntawm PVC-rau-PVC | Txuas PVC rau hlau threads |
| Hom | Mus tas li | Serviceable (tshem tawm) |
Puas yog PVC pob li qub kev taw qhia?
Cov cement yog npaj txhij, tab sis koj tsis kam, nrhiav ib tug xub ntawm lub valve lub cev. Gluing lub taw qhia valve nyob rau hauv rov qab yuav yog ib qho yuam kev kim, yuam koj ua kom puas.
Tsis yog, tus qauv PVC pob valve yog ob-txoj kev thiab yuav kaw cov dej sib npaug zoo los ntawm ob qho tib si. Nws txoj haujlwm tsis yog nyob ntawm qhov kev taw qhia ntws. Tsuas yog "kev taw qhia" uas tseem ceeb yog txhim kho nws kom koj tuaj yeem nkag mus rau tus kov thiab lub koom haum ceev.
Qhov no yog ib lo lus nug zoo uas qhia tau hais tias ua tib zoo xav. Koj yog txoj cai yuav tsum ceev faj, vim qee qhov li qub yog qhov taw qhia. Akos valve, piv txwv li, tsuas yog tso cai ntws mus rau hauv ib qho kev taw qhia thiab yuav muaj lub xub meej sau rau ntawm nws. Yog tias ntsia rov qab, nws tsuas yuav tsis ua haujlwm. Txawm li cas los xij, apob valvetsim yog symmetrical. Nws muaj ib lub pob nrog ib lub qhov los ntawm nws uas seals tiv thaiv lub rooj. Txij li thaum muaj lub rooj zaum ntawm ob sab ntug dej thiab sab qab teb, lub valve seals zoo kawg nkaus txawm tias txoj kev twg dej ntws. Yog li, koj tsis tuaj yeem nruab nws "rov qab" nyob rau hauv cov nqe lus ntawm ntws. Raws li kuv tau hais ua ntej, tsuas yog "kev taw qhia" koj yuav tsum txhawj xeeb yog qhov kev coj ua zoo rau kev siv lub valve. Koj tuaj yeem tig lub kov? Koj puas tuaj yeem nkag mus rau cov koom haum? Qhov ntawd yog qhov tseeb kev sim ntawm kev teeb tsa kom raug rau lub valve zoo li cov uas peb tsim ntawm Pntek.
Xaus
Rau qhov zoo meej PVC pob valve installation, siv cov primer thiab xis mas. Npaj rau kev tuav thiab kev sib koom tes txiv ntoo kom ntseeg tau tias muaj kev ruaj ntseg, tsis muaj pov thawj, thiab kev sib txuas tau zoo.
