Koj tau nplaum koj lub qhov dej PVC tshiab rau hauv cov kav dej, tab sis tam sim no nws xau. Ib qho sib txuas tsis zoo txhais tau tias koj yuav tsum txiav cov kav dej thiab pib dua, nkim sijhawm thiab nyiaj txiag.

Yuav kom txhim kho tau zooPVC pob valve, koj yuav tsum siv cov primer tshwj xeeb PVC thiabcov cement uas muaj kuab tshuajTxoj kev no suav nrog kev txiav cov yeeb nkab kom huv, tshem cov burr, pleev xim rau ob qho chaw, siv cov cement, thiab tom qab ntawd thawb thiab tuav qhov sib txuas kom ruaj khov rau 30 vib nas this kom tsim tau qhov vuam tshuaj mus tas li.

Cov txheej txheem no yog hais txog kev tsim cov tshuaj sib txuas uas muaj zog npaum li cov yeeb nkab nws tus kheej, tsis yog tsuas yog lo cov khoom ua ke xwb. Nws yog ib qho tseem ceeb uas kuv ib txwm hais txog nrog kuv cov neeg koom tes, zoo 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 taus qhov ua tsis tiav. Ib qho kev sib koom ua ke tsis zoo tuaj yeem ua rau lub sijhawm thiab peev nyiaj ntawm qhov project poob qis. Cia peb taug kev los ntawm cov lus nug tseem ceeb kom ntseeg tau tias txhua qhov kev teeb tsa koj ua haujlwm yog kev ua tiav ntev.

Yuav ua li cas koj thiaj li nruab lub pob valve rau ntawm PVC yeeb nkab?

Koj muaj cov khoom seem zoo, tab sis koj paub tias tsis muaj lub sijhawm thib ob nrog PVC cement. Ib qho yuam kev me me txhais tau tias txiav ib feem ntawm cov yeeb nkab thiab pib dua tshiab los ntawm kos.

Cov txheej txheem teeb tsa siv cov tshuaj yaj vuam thiab muaj tsib kauj ruam tseem ceeb: txiav cov yeeb nkab kom plaub fab, tshem cov npoo, siv PVC primer rau ob qho chaw, pleev xim nrog PVC cement, thiab tom qab ntawd thawb cov khoom ua ke nrog ib feem plaub tig thiab tuav lawv kom ruaj khov.

Kev ua kom cov txheej txheem no raug yog qhov sib txawv ntawm txoj haujlwm tshaj lij thiab teeb meem yav tom ntej. Cia peb piav qhia txhua kauj ruam kom meej. Qhov no yog cov txheej txheem tseeb uas kuv muab rau Budi cov neeg siv khoom kom lav qhov foob zoo meej.

1. Txiav & Tshem Tawm:Pib nrog kev txiav kom huv si thiab plaub fab ntawm koj lub yeeb nkab. Txhua lub kaum sab xis tuaj yeem ua rau muaj qhov sib txawv hauv qhov sib koom ua ke. Tom qab txiav, siv cov cuab yeej tshem tawm cov burr lossis riam yooj yim los txiav cov yas fuzz ntawm sab hauv thiab sab nraud ntawm ntug yeeb nkab. Cov burrs no tuaj yeem khawb cov cement tawm thiab tiv thaiv cov yeeb nkab kom tsis txhob zaum tag.
2. Thawj:Thov ib lub tsho tiv no ntawmPVC primer(feem ntau nws yog xim av) rau sab nraud ntawm lub yeeb nkab thiab sab hauv ntawm lub qhov (socket). Tsis txhob hla cov kauj ruam no! Cov tshuaj primer tsis yog tsuas yog ib qho tshuaj ntxuav xwb; nws pib ua kom cov yas mos, npaj nws rau kev sib txuas tshuaj.
3. Cement:Thaum lub primer tseem ntub, thov ib txheej sib npaug ntawm cov primer.PVC cementhla cov chaw uas tau pleev xim rau saum. Thov nws rau ntawm cov yeeb nkab ua ntej, tom qab ntawd muab cov txheej nyias dua rau ntawm lub qhov (valve socket).
4. Thawb, Tig & Tuav:Tam sim ntawd thawb lub yeeb nkab mus rau hauv lub qhov (socket) nrog rau kev tig ib feem plaub ntawm lub voj voog. Qhov kev tig no pab kom cov cement nthuav dav sib npaug. Tom qab ntawd koj yuav tsum tuav lub pob qij ua ke kom ruaj khov rau tsawg kawg 30 vib nas this. Cov tshuaj lom neeg ua rau muaj kev ntxhov siab uas yuav sim thawb lub yeeb nkab rov qab tawm.

Yuav ua li cas yog txoj hauv kev zoo los teeb tsa lub pob valve?

Lub valve nyob hauv, tab sis tus kov ntaus phab ntsa. Los yog qhov phem dua, koj tau teeb tsa lub valve sib koom ua ke tiag tiag ze rau lwm qhov sib txuas uas koj tsis tuaj yeem tau txais lub wrench ntawm cov txiv ntoo.

Txoj kev "yog" los teeb tsa lub pob valve xav txog kev siv yav tom ntej. Qhov no txhais tau tias xyuas kom meej tias lub tes tuav muaj qhov chaw puv 90-degree kom tig tau thiab cov txiv ntoo sib koom ua ke ntawm lub valve sib koom ua ke tiag tiag tuaj yeem nkag tau tag nrho rau kev saib xyuas yav tom ntej.

Ib qho kev teeb tsa zoo yog ntau tshaj li ib qho xwblub foob tsis xau; nws yog hais txog kev ua haujlwm mus sij hawm ntev. Qhov no yog qhov uas kev npaj me ntsis ua rau muaj qhov sib txawv loj heev. Qhov yuam kev feem ntau uas kuv pom yog qhov tsis muaj kev npaj rau kev nkag mus. Lub pob valve yuav tsum tig 90 degrees kom mus los ntawm qhov qhib tag nrho mus rau qhov kaw tag nrho. Ua ntej koj txawm qhib lub qhov dej cement, tuav lub valve rau hauv qhov chaw thiab co lub tes tuav los ntawm nws qhov kev txav mus los tag nrho. Xyuas kom tseeb tias nws tsis ntaus phab ntsa, lwm lub yeeb nkab, lossis lwm yam. Qhov thib ob, tshwj xeeb tshaj yog rau peb Pntekqhov tseeb union valves, yog kev nkag mus rau lub koom haum. Tag nrho cov txiaj ntsig ntawm kev tsim lub koom haum tiag tiag yog tias koj tuaj yeem unscrew cov koom haum thiab tsa lub cev tseem ceeb tawm rau kev kho lossis hloov pauv yam tsis tau txiav lub yeeb nkab. Kuv ib txwm ceeb toom Budi kom hais qhov no rau nws cov neeg siv khoom cog lus. Yog tias koj teeb tsa lub valve qhov twg koj tsis tuaj yeem tau txais lub wrench ntawm cov txiv ntoo ntawd, koj nyuam qhuav tig lub valve zoo, siv tau rau hauv tus qauv, pov tseg.

Yuav ua li cas txuas lub valve rau PVC yeeb nkab?

Koj lub qhov dej muaj xov, tab sis koj lub yeeb nkab du. Koj xav paub seb koj puas yuav tsum nplaum nws, xov nws, lossis yog tias ib txoj kev zoo dua li lwm txoj kev rau kev sib txuas ruaj khov.

Muaj ob txoj kev tseem ceeb: kev vuam siv cov tshuaj yaj (gluing) rau qhov ruaj khov, sib txuas ua ke, thiab kev sib txuas xov rau qhov sib koom ua ke uas tuaj yeem rhuav tshem tau. Rau cov kab ke PVC-rau-PVC, kev vuam siv cov tshuaj yaj yog txoj kev muaj zog dua thiab siv ntau dua.

Kev xaiv hom kev sib txuas zoo yog qhov tseem ceeb. Feem ntau ntawm cov kab ke PVC vam khomkev vuam tshuaj, thiab rau qhov laj thawj zoo. Nws tsis yog tsuas yog lo cov khoom ua ke xwb; nws sib xyaw ua ke lawv rau hauv ib daim yas uas muaj zog heev thiab tsis xau. Cov xov sib txuas muaj lawv qhov chaw, tab sis lawv kuj muaj qhov tsis muaj zog. Lawv muaj txiaj ntsig thaum txuas lub valve PVC rau lub twj tso kua mis hlau lossis lub tank uas twb muaj xov lawm. Txawm li cas los xij, cov xov yas sib txuas tuaj yeem yog qhov chaw xau yog tias tsis kaw kom zoo nrog daim kab xev Teflon lossis nplaum. Qhov tseem ceeb tshaj, kev nruj dhau ntawm cov yas sib txuas yog qhov yuam kev uas tuaj yeem tawg qhov txuas poj niam, ua rau tsis ua haujlwm.

Kev Sib Piv Txoj Kev Txuas

Cov pob valve PVC puas yog directional?

Cov cement twb npaj txhij lawm, tab sis koj ua siab deb, nrhiav tus xub ntawm lub cev valve. Kev nplaum lub valve uas tig mus rau sab nraud yuav yog qhov yuam kev kim heev, yuam kom koj rhuav tshem nws.

Tsis yog, lub pob valve PVC txheem yog ob txoj kev thiab yuav kaw qhov dej ntws zoo sib npaug los ntawm ob txoj kev. Nws txoj haujlwm tsis yog nyob ntawm qhov kev taw qhia ntawm qhov dej ntws. Tsuas yog "kev taw qhia" uas tseem ceeb yog kev teeb tsa nws kom koj tuaj yeem nkag mus rau qhov kov thiab cov txiv ntoo sib koom ua ke.

Qhov no yog ib lo lus nug zoo heev uas qhia txog kev xav zoo. Koj hais yog lawm kom ceev faj, vim qee lub valve yeej muaj kev taw qhia.lub valve, piv txwv li, tsuas yog tso cai rau ntws mus rau hauv ib qho kev taw qhia thiab yuav muaj tus xub pom tseeb luam tawm rau nws. Yog tias ntsia rov qab, nws tsuas yog yuav tsis ua haujlwm. Txawm li cas los xij, iblub pob valvetsim yog symmetrical. Nws muaj ib lub pob nrog ib lub qhov hla nws uas kaw rau ntawm lub rooj zaum. Vim tias muaj ib lub rooj zaum ntawm ob sab saud thiab sab hauv qab, lub valve kaw zoo kawg nkaus tsis hais qhov twg dej ntws. Yog li, koj tsis tuaj yeem teeb tsa nws "rov qab" hauv cov nqe lus ntawm kev ntws. Raws li kuv tau hais ua ntej, tsuas yog "kev taw qhia" koj yuav tsum txhawj txog yog qhov kev taw qhia siv rau kev siv lub valve. Koj puas tuaj yeem tig lub tes tuav? Koj puas tuaj yeem nkag mus rau cov koom haum? Qhov ntawd yog qhov kev sim tiag tiag ntawm kev teeb tsa kom raug rau lub valve zoo li cov uas peb tsim ntawm Pntek.

Xaus lus

Yog xav kom lub pob valve PVC zoo meej, siv cov primer thiab cement kom raug. Npaj kom muaj qhov nkag mus rau ntawm tus kov thiab lub union nut kom ntseeg tau tias muaj kev sib txuas zoo, tsis xau, thiab siv tau.
