PVC-U cov kav dej yog ib yam ntawm cov kav dej nrog cov thev naus laus zis. Nws muaj cov yam ntxwv ntawm lub neej ntev kev pab cuam, corrosion kuj, lub teeb yuag thiab yooj yim tuav thiab installation. Nws yog dav siv nyob rau hauv sab hauv tsev thiab sab nraum zoov lub raj xa dej engineering hauv industrial thiab civil vaj tse. Muaj peb hom PVC-U cov kav dej: cov yeeb nkab ncaj, cov yeeb nkab flared, thiab cov yeeb nkab flared, nrog rau ntau txoj kev sib txawv ntawm cov yeeb nkab txuas.
Cov kauj ruam txuas ntawm PVC-U cov kav dej:
So cov qhov (sockets) thiab qhov (socket) ntawm cov kav dej thiab fittings kom huv si ua ntej kev sib txuas; ntsuas qhov tob ntawm lub qhov (socket) thiab kos cov yeeb nkab chaw nres nkoj; dipped ib qho txhuam me me rau hauv qhov tsim nyog ntawm cov nplaum, thiab pleev xim rau qhov sib koom ua ke ntawm cov kav dej thiab fittings. Ua ntej siv lub qhov (socket) rau lub qhov (socket), qhov kev txiav txim yog sai thiab sib npaug; Tom qab siv cov nplaum nplaum, tam sim ntawd ntxig lub raj rau hauv lub qhov (socket) mus rau lub cim nyob rau hauv qhov tseeb, tig 1/4 tig thiab khaws cia rau 2-3 feeb kom tsis txhob cuam tshuam qhov cuam tshuam; Tom qab lub qhov (socket) muab tso rau hauv, so cov nplaum nplaum rau ntawm lub qhov (socket) nrog paj rwb xov paj los yog ib daim ntaub qhuav dipped nyob rau hauv ib tug tu tus neeg sawv cev; cov yeeb nkab sib txuas yuav tsum tau tso cai kom sawv ntsug kom txog thaum lub interface kho tau raws li qhov ua tau zoo ntawm cov nplaum thiab cov xwm txheej huab cua. Piv txwv li, thaum lub sij hawm tsim kho nyob rau hauv lub caij ntuj no los yog los nag, lub sij hawm kho yuav tsum tau ncua kom tsim nyog.
Kev ceev faj rau PVC-U kua kav dej installation:
Cov nplaum nplaum thiab cov tshuaj ntxuav tes yuav tsum tau qhib thiab siv tam sim ntawd, thiab cov neeg ua haujlwm tsis yog yuav tsum tsis txhob siv lawv ntawm qhov siab; hnav hnab looj tes thaum siv cov nplaum nplaum, thiab yog tias lawv yuam kev lo rau ntawm lub qhov muag, yaug nrog dej kom ntau thiab xa mus rau kws kho mob kom kuaj xyuas; Cov cuab yeej siv cov yeeb nkab yuav tsum tau siv Rau cov cuab yeej xws li cov hniav zoo nkauj, cov cutters thiab cov yeeb nkab cutters, cov txiav yuav tsum tiaj tus thiab perpendicular rau cov yeeb nkab lub cev, thiab yuav tsum tsis txhob muaj deformation ntawm seem; lub qhov (socket) yuav tsum tau ua ntaub ntawv nrog ib tug nruab nrab phaj ntaub ntawv los ua ib tug zawj ntawm 15 ° -30 °, thiab lub thickness ntawm lub zawj yuav tsum yog 1/3-1/2 ntawm cov yeeb nkab phab ntsa thickness, thiab qhov ntev yog feem ntau tsis tsawg. tshaj 3mm. Tom qab qhov zawj tiav lawm, cov khib nyiab yuav tsum tau muab tshem tawm.
