Kev txhim kho ntawm PEX compression fittings muaj keeb kwm ntev thiab nplua nuj. Thawj qhov hais txog PEX (cross-linked polyethylene) yog nyob rau xyoo 1950, tab sis nws tsis yog txog thaum xyoo 1980s uas PEX kav thiab fittings tau qhia rau lub lag luam thoob ntiaj teb. Txij thaum ntawd los, PEX tau dhau los ua qhov kev xaiv nrov rau cov kav dej hauv ntau lub tebchaws.
Thaum ntxov ntawm PEX, fittings feem ntau yog ua los ntawm tooj dag, uas yog cov khoom siv txhim khu kev qha tab sis kim. Txawm li cas los xij, nyob rau xyoo 1990, cov khoom siv yas tau pib muaj koob meej vim lawv cov nqi qis thiab siv tau yooj yim. PEX compression fittings tau qhia nyob rau lub sijhawm no, thiab lawv tau dhau los ua qhov kev xaiv zoo tshaj plaws rau ntau tus installers.
PEX compression fittings yog tsim los tsim cov dej tsis sib haum ntawm PEX yeeb nkab thiab qhov haum nws tus kheej. Qhov haum muaj ob qhov chaw - lub nplhaib compression thiab lub txiv ntoo compression. Lub nplhaib compression yog muab tso rau ntawm qhov kawg ntawm PEX yeeb nkab, thiab cov txiv ntoo compression yog threaded mus rau lub cev haum. Raws li cov txiv ntseej nruj, nws compresses lub nplhaib, tsim kom muaj kev sib khi ntawm cov yeeb nkab thiab qhov haum.
Ib qho zoo ntawm PEX compression fittings yog tias lawv tuaj yeem ntsia tau yooj yim yam tsis tas siv cov cuab yeej tshwj xeeb. Tsis zoo li crimp fittings, uas yuav tsum tau ib tug crimping cuab tam los tsim ib tug kev twb kev txuas, PEX compression fittings yuav nruj nreem siv ib tug wrench los yog pliers. Qhov no ua rau lawv muaj kev xaiv nrov rau DIY cov kav dej.
Tau ntau xyoo, PEX compression fittings tau hloov kho thiab txhim kho. Cov ntaub ntawv tshiab tau tsim los txhim kho cov kav ntev thiab ntev, thiab cov tuam ntxhab tau qhia cov qauv tshiab uas ua rau kev teeb tsa yooj yim dua. Piv txwv li, qee qhov PEX compression fittings tuaj nrog cov txiv ntseej ua ntej thiab lub nplhaib, uas tshem tawm qhov xav tau rau cov neeg tsim khoom kom xaub lub nplhaib mus rau hauv cov yeeb nkab ua ntej kev teeb tsa.
Lwm qhov kev hloov tshiab tsis ntev los no hauv PEX compression fittings yog qhov ntxiv ntawm qhov nres nres. Qhov no feature tiv thaiv lub installer los ntawm overtightening lub txiv ntoo, uas yuav ua rau lub compression nplhaib deform thiab cuam tshuam lub foob. Nrog rau qhov nres feature, lub installer tsuas yog zawm lub txiv ntoo kom txog thaum nws nres, kom ntseeg tau tias qhov haum ruaj ntseg yam tsis muaj kev puas tsuaj rau lub nplhaib.
Hauv kev xaus, kev txhim kho ntawm PEX compression fittings tau ntev thiab tsis tu ncua. Cov fittings no tau dhau los ua qhov kev xaiv nrov rau cov kav dej vim lawv qhov yooj yim ntawm kev teeb tsa, tus nqi pheej yig, thiab kev ua tau zoo. Raws li kev siv thev naus laus zis txuas ntxiv mus, peb tuaj yeem cia siab tias yuav pom cov qauv tsim tshiab thiab cov khoom siv yav tom ntej.
