PPR yeeb nkab yog cov khoom siv dav siv nyob rau xyoo tas los no, dav siv hauv cov dej thiab cov kav dej, roj, hluav taws xob thiab lwm yam haujlwm. PChouse yuav saib seb PPR raj feem ntau txuas nrog koj li cas hnub no.
1. Kub yaj kev twb kev txuas
Txoj kev sib txuas no yuav tsum tau siv tib hom thermoplastic yeeb nkab fittings. Ua ntej, siv lub tshuab cua sov tshwj xeeb los ua kom sov qhov sib txuas kom yaj nws, thiab tom qab ntawd nias ob lub kav dej los txuas rau lawv ua ke. Txoj kev no kuj muaj ntau heev thiab yooj yim.
Ob leeg PPR kav thiab PPR ntxig cov pob qij txha tuaj yeem txuas ncaj qha los ntawm cov qhov hluav taws xob kub.
2. Kev sib txuas hluav taws xob
Thaum txuas tib hom thermoplastic yeeb nkab, muab ib qho tshwj xeeb electrofusion yeeb nkab haum rau nws, energize lub electrofusion yeeb nkab haum, thiab lub tshav kub generated los ntawm cov kuj hlau nyob rau hauv lub electrofusion yeeb nkab haum yuav welded. Tom qab txias, cov yeeb nkab haum thiab electrofusion yeeb nkab haum yuav txuas nrog tag nrho.
3. Flange kev twb kev txuas
Flange kev twb kev txuas yog kho ob lub kav dej, cov yeeb nkab fittings lossis cov khoom siv ntawm lub phaj flange, tom qab ntawd ntxiv lub flange gasket ntawm ob lub flange daim hlau, thiab thaum kawg nruj ob lub flange daim hlau nrog bolts Ib qho kev sib koom ua ke uas yog nruj nreem kaw. Kev sib txuas los ntawm cov kav dej nyob ruaj ruaj mus rau cov khoom sib hloov lossis cov khoom siv sib txuas tau ua tau. Thaum sib txuas, koj tuaj yeem siv kub yaj los yog kev sib txuas.
4. Mechanical kev twb kev txuas
Thaum cov khoom siv hlau los yog cov yas muaj zog siv los ua cov yeeb nkab fittings, cov cuab yeej tshwj xeeb yog siv los txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhuam cov yeeb
