Taw qhia:
Hauv thaj av ntawm cov kav dej, cov txheej txheem kev sib khi yog qhov tseem ceeb rau kev ua tiav kev sib txuas tsis muaj paug thiab ruaj khov hauv cov khoom siv dej thiab kev faib khoom. Kev kaw cov kav dej kom raug tsis yog tsuas yog tiv thaiv cov dej khib nyiab xwb tab sis kuj tiv thaiv kev puas tsuaj los ntawm kev xau. Kab lus no qhia txog ntau yam kev sib khi uas feem ntau ua haujlwm hauv cov kav dej phwj, qhia txog lawv qhov zoo, kev siv, thiab kev xav.
1. Threaded Sealing: Ua kom cov pob qij txha nruj
Threaded kev twb kev txuas tseem yog ib txoj hauv kev rau kev koom nrog cov kav dej fittings. Siv cov xov ntawm cov kav dej thiab fittings, cov ntaub ntawv zoo li Teflon daim kab xev los yog cov yeeb nkab dope yog siv rau cov xov. Cov ntaub ntawv no sau qhov khoob thiab tsim kom muaj kev ruaj ntseg foob, txo qhov kev pheej hmoo ntawm kev xau. Threaded sealing yog tsim rau cov ntawv thov nrog lub siab nruab nrab thiab tuaj yeem ua haujlwm nrog cov hlau thiab qee yam yas.
2. Compression Sealing: Zoo tagnrho rau kev siv ntau yam
Compression fittings cia siab rau compression txiv ntoo kom nruj cov kav dej thiab fittings ua ke. Lub nplhaib compression yog muab tso rau nruab nrab ntawm cov txiv ntseej thiab haum, tsim kom muaj kev sib khi ruaj khov thaum cov txiv ntseej nruj. Cov txheej txheem no haum rau ntau yam khoom siv, los ntawm tooj liab mus rau yas, ua rau nws muaj ntau yam rau ntau lub kav dej.
3. Welding thiab Soldering: Ua kom ruaj khov ruaj khov
Vuam thiab soldering koom nrog melting cov khoom muab tub lim los tsim kom muaj kev sib txuas ruaj khov, tsis muaj pov thawj. Nyob rau hauv vuam, hlau yog fused ua ke, thaum soldering siv ib tug qis-melting-point khoom mus koom hlau los yog tej yam yas. Cov txheej txheem no feem ntau yog siv rau cov kav dej tooj liab thiab fittings thiab tshwj xeeb tshaj yog siv tau rau hauv cov ntawv thov kub.
4. Push-Fit Sealing: Kev sib txuas nrawm thiab siv tau zoo
Push-fit fittings yog tsim los rau kev siv zog ua haujlwm tsis tas yuav muaj cov cuab yeej tshwj xeeb. Cov fittings muaj O-rings uas tsim cov dej tsis sib haum raws li cov yeeb nkab raug thawb rau hauv qhov haum. Txoj kev no yog tus neeg siv khoom zoo thiab tuaj yeem siv nrog ntau yam khoom siv yeeb nkab, suav nrog tooj liab, PEX, thiab CPVC.
5. Flanged Joints: Txhim khu kev sib khi rau cov kav dej loj
Flanged pob qij txha yog siv rau cov kav dej loj thiab cov tshuab ua haujlwm siab. Gaskets muab tso rau ntawm flanges thiab ces bolted ua ke, tsim kom muaj kev ruaj ntseg foob. Cov txheej txheem no tau txais kev pom zoo rau nws txoj kev ntseeg siab hauv cov ntawv thov kev lag luam thiab qhov twg yuav tsum tau ua kom nquag plias.
Kev txiav txim siab:
Thaum xaiv cov txheej txheem sealing, yam xws li siab, qhov kub thiab txias, cov khoom siv sib xws, thiab kev yooj yim ntawm kev teeb tsa yuav tsum tau ua tib zoo xav. Cov kev sib txuas tsis raug kaw tuaj yeem ua rau cov xau, corrosion, thiab lwm yam teeb meem, ua rau muaj kev saib xyuas ntxiv thiab kev puas tsuaj.
Xaus:
Cov txheej txheem sealing zoo yog qhov tseem ceeb hauv kev tswj xyuas kev ncaj ncees ntawm cov kav dej. Txhua txoj kev hais txog ntawm no muaj qhov tshwj xeeb zoo nyob ntawm qhov tshwj xeeb yuav tsum tau ua ntawm kev siv cov kav dej. Los ntawm kev nkag siab thiab siv cov txheej txheem sealing tsim nyog, cov kws tshaj lij cov kav dej tuaj yeem ua kom muaj kev sib txuas tsis muaj paug, ua rau muaj txiaj ntsig zoo thiab siv tau ntev ntawm cov dej xau thiab kev faib khoom.
