Lub tswvyim
Cia peb saib ze dua ntawm "ductile hlau yeeb nkab fittings". Qhov no yog ib lub tswv yim tseem ceeb heev vim hais tias nyob rau hauv qhov tseeb pipeline engineering, cov kav dej ncaj nraim yog lub hauv paus xwb; ntau yam yeeb nkab fittings yog tus yuam sij rau kev hloov cov kev taw qhia ntawm lub raj xa dej, branching, txo txoj kab uas hla, thiab kev sib txuas.
Ductile hlau yeeb nkab fittings yog cov yeeb nkab sib txuas ua los ntawm cov hlau ductile. Lawv muab cov khoom siv tib yam li cov kav hlau ncaj ncaj (lub zog siab, siab tawv, tiv thaiv corrosion) thiab txuas nrog cov kav dej ncaj nraim lossis lwm cov yeeb nkab fittings los ntawm kev sib txuas lus tshwj xeeb (xws li T- hom, K- hom, thiab flange hom) los tsim kom tiav thiab kaw cov kav dej.
Cov yam ntxwv tseem ceeb
01. Cov khoom siv zoo heev: Nws tau txais txhua qhov zoo ntawm cov hlau nplaum, nrog lub zog siab thiab zoo toughness, thiab tuaj yeem tiv taus siab sab hauv thiab sab nraud load.
02. Kev ruaj ntseg sealing: Thaum siv cov kav dej ncaj ntawm cov khoom siv tib yam thiab cov qauv, kev sib khi ua haujlwm ntawm cov kev sib tshuam zoo ib yam, kom ntseeg tau tias tsis muaj qhov xau hauv tag nrho cov kav dej.
03. High durability: Ntev tsim lub neej, feem ntau synchronized nrog ncaj kav, mus txog 50-100 xyoo.
04. Ua kom tiav ntau yam ntawm cov kev qhia tshwj xeeb: Muaj ntau ntau hom muaj los ua kom tau raws li ntau yam kev xav tau ntawm cov raj xa dej.
05. Standardization: Kev tsim khoom ua raws li cov qauv thoob ntiaj teb (xws li ISO 2531) lossis cov qauv hauv tebchaws (xws li GB / T 13295) kom ntseeg tau tias muaj kev sib hloov thiab kev sib raug zoo.
Hom thiab siv
1. Kev Taw Qhia Hloov Fittings
Siv los hloov cov kev taw qhia ntawm cov kav dej.
Luj tshib: Feem ntau siv yeeb nkab fittings.
90℃Luj tshib: Hloov cov kev taw qhia ntawm cov yeeb nkab los ntawm 90 degrees.
45℃Luj tshib: Hloov cov kev taw qhia ntawm cov yeeb nkab los ntawm 45 degrees.
22.5℃Luj tshib, 11.25℃Luj tshib: Siv rau cov xwm txheej uas yuav tsum tau hloov lub kaum sab xis.
2. Hom kev faib thiab hloov pauv
Siv los txuas cov kav dej los ntawm cov yeeb nkab loj.
Tees:
Equal Diameter Tees: Tag nrho peb qhov hluav taws xob muaj tib txoj kab uas hla.
Txo Tees: Cov ceg yeeb nkab txoj kab uas hla yog me dua lub ntsiab yeeb nkab txoj kab uas hla.
Plaub-Txoj Kev Tees: Cov ceg ntoo hauv plaub txoj kev; tsawg dua, siv nyob rau hauv txoj kev sib tshuam cov yeeb nkab sib txuas.
3. Txo cov fittings
Siv los txuas cov kav dej sib txawv.
Reducers (Uniform Reducers):
Concentric Reducers: Cov kab nruab nrab yog ua raws; siv rau cov kav dej ntsug lossis cov xwm txheej xav tau kev sib tw.
Eccentric Reducers: Ib sab ntawm cov yeeb nkab phab ntsa yog ntws; Feem ntau siv rau cov kav dej kab rov tav kom tswj tau cov yeeb nkab zoo ib yam hauv qab lossis saum toj kawg nkaus thiab tiv thaiv cov hnab ris huab cua lossis cov khoom seem.
4. Kev sib txuas thiab kev txiav tawm
Siv rau kev sib txuas tshwj xeeb lossis kaw cov kav dej.
Lub tes tsho (Short Pipe): Siv los txuas ob lub kav dej ncaj nraim uas tsis tuaj yeem cuam tshuam ncaj qha.
Yeeb Nkab Plug (Dig Muag Flange): Siv mus tas li lossis ib ntus kaw qhov kawg ntawm cov kav dej.
Flange / Socket: Ib kawg yog qhov sib txuas ntawm cov yeeb nkab txheem (socket lossis spigot), thiab lwm qhov kawg yog flange. Siv los txuas rau li qub, twj tso kua mis, lossis lwm yam khoom siv flanged, ua tiav kev hloov ntawm cov kav dej mus rau cov khoom siv.
Kho clamps: Tsis yog - qauv yeeb nkab fittings, tab sis tseem ceeb heev. Siv rau kev kho sai thaum cov kav dej xau vim yog kev puas tsuaj, tsis tas yuav hloov tag nrho cov yeeb nkab seem. Hom kev sib txuas yog tib yam li cov kav dej ncaj, thiab cov fittings yog nruab nrog cov sib txuas sib txuas uas yuav tsum tau sib xws nrog cov kav dej ncaj nraim los yog cov khoom siv sib txuas.
T- hom swb- hauv interface:
Qhov feem ntau saj zawg zog interface. Ib qho kawg ntawm qhov haum yog lub qhov (socket) ua tau - hauv cov nplhaib roj hmab), thiab lwm qhov kawg yog lub qhov ncauj. Nws muab kev yooj yim installation thiab sealing zoo heev.
K- hom mechanical interface:
Lub foob tau ua tiav los ntawm kev zawm lub nplhaib roj hmab nrog bolts thiab caj pas, uas muab kev sib txuas ntau dua rigidity thiab rub - tawm tsis kam.
Flange kev twb kev txuas: Ob lub flanges yog fastened ua ke nrog bolts, thiab ib tug gasket yog sandwiched nyob rau hauv nruab nrab ntawm sealing. Feem ntau yog siv los txuas rau cov khoom siv lossis cov kav dej uas yuav tsum tau ua kom nquag plias. Ntau cov yeeb nkab fittings yog kev sib txuas; Piv txwv li, ib lub tee yuav muaj ob lub T-socket pob qij txha thiab ib tug T-spigot sib koom, los yog ib tug flange sib koom.
Sib piv txoj cai
Cov ntaub ntawv thiab cov qauv:
Nws yuav tsum xyuas kom meej tias cov fittings thiab cov kav dej ncaj nraim ua raws li cov qauv qub (xws li ISO, GB, EN, thiab lwm yam).
01
Qib siab:
Lub siab ntsuas ntawm cov fittings (piv txwv li, K9) yuav tsum tsis txhob qis dua ntawm cov yeeb nkab txuas ncaj nraim.
02
Hom interface:
Hom haum yuav tsum yog ib qho zoo meej match rau cov yeeb nkab ncaj. Ib qho T-kho yuav tsum haum nrog ib lub T-socket.
03
Sab hauv thiab sab nraud tiv thaiv corrosion:
Zoo ib yam li cov kav dej ncaj, cov yeeb nkab hlau txuas rau cov khoom siv dej feem ntau muaj cov cement mortar hauv ob sab phlu thiab cov epoxy asphalt lossis zinc txheej + asphalt pleev xim rau kev tiv thaiv corrosion ntawm phab ntsa sab nrauv. Hauv qhov tshwj xeeb corrosive ib puag ncig (xws li cov av acidic), kev tiv thaiv corrosion yuav tsum tau teev tseg.
04
Installation Notes:
Kev Tu: Nco ntsoov ntxuav lub qhov (socket), lub taub hau thiab lub nplhaib roj hmab ua ntej kev teeb tsa kom tsis txhob muaj impurities cuam tshuam rau lub foob.
Lubrication: Siv lub siab, tsis yog{0}} cov roj nplua nyeem ua kom yooj yim installation thiab tiv thaiv lub nplhaib roj hmab.
Marking: Kos qhov tob tob ntawm lub qhov (socket) kom paub meej tias kev teeb tsa kom raug.
Alignment: Thaum siv cov cuab yeej tsim nyog (xws li cov pas tuav los yog cov tensioners), xyuas kom cov kav dej thiab cov khoom sib txuas kom tsis txhob muaj kev sib tsoo lossis sib tw ntawm cov roj hmab nplhaib.
