Koj ua tib zoo ntsia lub xov tshiab PVC valve, tab sis nws maj mam poob los ntawm cov xov. Tightening nws xav tias txaus ntshai, raws li koj paub tias ib qho tig ntau dhau tuaj yeem tawg qhov haum.
Txhawm rau kom ua tiav cov txheej txheem PVC pob valve, qhwv cov txiv neej xov nrog 3-4 txheej ntawm Teflon daim kab xev. Ib txwm qhwv nyob rau hauv cov kev taw qhia ntawm zawm. Tom qab ntawd, ntswj nws hauv tes nruj, thiab siv tus ciaj ntswj tsuas yog ib lossis ob zaug kawg nkaus.
Ib txoj xov xaim yog ib qho ntawm feem ntau thiab kev ntxhov siab ntawm kev teeb tsa tsis ua haujlwm. Nws yuav luag ib txwm tshwm sim los ntawm ib qho me me, zam tsis tau yuam kev hauv kev npaj lossis zawm. Kuv feem ntau tham txog qhov no nrog kuv tus khub hauv Indonesia, Budi, vim tias nws mob taub hau tas li nws cov neeg siv khoom ntsib. Kev ruaj ntseg, xau-dawb threaded kev twb kev txuas yog ua tau yooj yim mus cuag. Koj tsuas yog yuav tsum ua raws li ob peb yam yooj yim, tab sis tseem ceeb heev, cov kauj ruam. Cia peb npog cov lus nug tseem ceeb kom ua tiav txhua lub sijhawm.
Yuav ua li cas rau nruab threaded PVC yeeb nkab fittings?
Koj siv cov xov sealant muab tshuaj txhuam uas ua haujlwm zoo ntawm cov hlau, tab sis koj lub PVC haum tseem xau. Qhov phem tshaj, koj txhawj xeeb cov tshuaj nyob rau hauv muab tshuaj txhuam yuav ua rau cov yas puas thaum lub sij hawm.
Rau threaded PVC, ib txwm siv Teflon daim kab xev es tsis txhob cov yeeb nkab dope los yog muab tshuaj txhuam. Qhwv cov txiv neej threads 3-4 zaug nyob rau hauv tib txoj kev koj yuav zawm lub haum, xyuas kom meej daim kab xev lays tiaj tus thiab du los tsim ib tug zoo meej foob.
Qhov sib txawv ntawm daim kab xev thiab muab tshuaj txhuam yog qhov tseem ceeb rau cov khoom siv yas. Ntau yamcev dopmuaj cov roj av-raws li cov tebchaw uas tuaj yeem siv tshuaj tua kab mob PVC, ua rau nws nkig thiab yuav tawg nyob rau hauv ib txwm ua haujlwm siab.Teflon daim kab xev, ntawm qhov tod tes, yog inert kiag li. Nws ua raws li ob qho tib si sealant thiab lubricant, sau cov qhov khoob me me hauv cov xov yam tsis tsim kom muaj qhov txaus ntshai sab nraud uas muab tshuaj txhuam tau. Qhov no tiv thaiv kev ntxhov siab ntawm tus poj niam haum.
Kev xaiv Sealant rau PVC xov
| Sealant | Pom zoo rau PVC? | Vim li cas? |
|---|---|---|
| Teflon daim kab xev | Yog (Qhov Zoo Tshaj Plaws) | Inert, tsis muaj tshuaj tiv thaiv, muab lubrication thiab sealing. |
| Pipe Dope (paste) | Tsis yog (Generally) | Ntau yam muaj cov roj uas muag muag lossis ua rau PVC yas ua rau lub sijhawm. |
| PVC-Rated Sealant | Yog (Siv nrog ceev faj) | Yuav tsum tau ntsuas tshwj xeeb rau PVC; daim kab xev tseem muaj kev nyab xeeb thiab yooj yim dua. |
Thaum koj qhwv cov xov, nco ntsoov mus rau hauv ib qho kev taw qhia clockwise thaum koj saib qhov kawg ntawm qhov haum. Qhov no ua kom ntseeg tau tias thaum koj nruj lub valve, daim kab xev yog smoothed es tsis yog bunched thiab unraveled.
Yuav ua li cas rau nruab ib lub pob valve ntawm PVC yeeb nkab?
Koj muaj lub pob valve tab sis koj cov yeeb nkab yog du. Koj yuav tsum tau txuas rau lawv, tab sis koj paub tias koj tsis tuaj yeem ua cov kua nplaum los yog xov cov yeeb nkab du. Dab tsi yog qhov haum?
Txhawm rau txuas lub pob valve rau cov yeeb nkab PVC du, koj yuav tsum ua ntej hnyav-weld (kua nplaum) PVC txiv neej threaded adapter rau hauv cov yeeb nkab. Tom qab cov cement tau kho tag nrho, koj tuaj yeem nruab lub threaded valve rau ntawm adapter.
Koj tsis tuaj yeem tsim cov xov ntawm tus qauv, du PVC yeeb nkab; phab ntsa yog nyias thiab nws yuav poob tam sim ntawd. Kev sib txuas yuav tsum tau ua nrog lub adapter haum. Rau txoj haujlwm no, koj xav tau aPVC Txiv neej Adapter(feem ntau hu ua MPT lossis MIPT adapter). Ib sab muaj lub qhov (socket) du, thiab lwm yam yog molded txiv neej threads. Koj siv tus txheej txheem PVC primer thiab cement txheej txheem rau chemically weld lub qhov (socket) kawg rau koj cov yeeb nkab, tsim ib qho, fused piece. Qhov tseem ceeb ntawm no yog kev ua siab ntev. Koj yuav tsum cia qhov ntawdhnyav-weld khokiag li ua ntej siv tej torque rau cov threads. Kev siv quab yuam ntxov dhau tuaj yeem rhuav tshem cov tshuaj lom neeg tshiab, tsim kom muaj cov pa tawm ntawm qhov sib koom ua ke. Kuv ib txwm qhia Budi cov neeg siv khoom kom tos tsawg kawg 24 teev kom muaj kev nyab xeeb.
Yuav ua li cas rau nruab ib threaded valve?
Koj tau ceev koj cov xov tshiab tshiab kom txog thaum nws hnov zoo li pob zeb, tsuas yog hnov mob tawg. Tam sim no lub valve puas lawm, thiab koj yuav tsum txiav nws tawm thiab pib tag nrho.
Txoj kev nruj nruj yog "tes nruj ntxiv rau ib mus rau ob zaug." Tsuas yog ntsia hlau lub valve ntawm tes kom txog thaum nws snug, ces siv ib tug ciaj ntswj los muab nws tsuas yog ib los yog ob zaum kawg lem. Nres qhov ntawd.
Tshaj-tightening yog tus thib ib ua rau tsis ua hauj lwm rau threaded yas fittings. Tsis zoo li cov hlau, uas tuaj yeem ncab thiab deform, PVC yog nruj. Thaum koj crank down ntawm ib tug threaded PVC valve, koj tab tom tso lub zog sab nraud ntawm tus poj niam haum cov phab ntsa, sim faib nws qhib. Qhov "tes nruj ntxiv ib mus rau ob zaug"Txoj cai yog tus qauv kub vim yog vim li cas, tes-tightening ib leeg tau txais cov xov zoo sib xws. Qhov kawg ib los yog ob lub lem nrog ib tug ciaj ntswj yog txaus los compress cov khaubncaws sab nraud povtseg ntawm Teflon daim kab xev, tsim ib tug zoo meej, dej-nruj foob yam tsis muaj kev nyuaj siab rau cov yas.
Yuav ua li cas txuas lub kaw valve rau PVC?
Koj yuav tsum tau ntxiv qhov kaw rau ib kab PVC uas twb muaj lawm. Koj tsis paub meej tias koj yuav tsum siv lub valve los yog tus qauv glued valve rau daim ntawv thov tshwj xeeb no.
Txhawm rau ntxiv qhov kaw rau ntawm cov kab PVC uas twb muaj lawm, qhov tseeb lub pob valve yog qhov kev xaiv zoo tshaj plaws. Nws tso cai rau kev saib xyuas yav tom ntej. Siv cov kuab tshuaj-weld (socket) version rau cov tshuab PVC ntshiab, lossis cov xov xov yog txuas ze ntawm cov khoom siv hlau.
Thaum koj yuav tsum tau txiav rau hauv ib txoj kab ntxiv rau kev kaw, xav txog yav tom ntej yog qhov tseem ceeb. Lub union pob valve yog qhov kev xaiv zoo tshaj ntawm no. Koj tuaj yeem txiav cov yeeb nkab, nplaum ob lub koom haum xaus rau, tom qab ntawd nruab lub valve lub cev ntawm lawv. Qhov no yog qhov zoo dua li tus qauv valve vim tias koj tuaj yeem yooj yim unscrew lub union txiv ntseej kom tshem tawm tag nrho lub cev lub cev rau kev ntxuav lossis hloov tsis tau txiav cov yeeb nkab dua. Yog tias koj qhov system yog 100% PVC, qhov hnyav-weld (socket) qhov tseeb union valve yog zoo meej. Yog tias koj ntxiv qhov kaw-tawm ntawm ib sab ntawm lub twj tso kua mis lossis lim nrog cov xov hlau, ces ib lub xovtiag union valveyog txoj kev mus. Koj yuav muab cov hlua khi rau ntawm cov yeeb nkab PVC ua ntej, tom qab ntawd nruab lub valve. Qhov kev hloov pauv no yog vim li cas peb ntawm Pntek hais txog kev tsim lub koomhaum tiag tiag.
Xaus
Yuav kom txhim kho ib tug threaded zooPVC pob valve, siv Teflon daim kab xev, tsis muab tshuaj txhuam. Tighten los ntawm tes ua ntej, tom qab ntawd ntxiv ib los yog ob zaug ntxiv nrog ib tug ciaj ntswj rau lub foob zoo meej.
