Kav hlau: kev yam ntxwv, xws li ntaus, txoj kab uas hla

Lub ntsiab tivthaiv ntawm tej ntawm engineering tes hauj lwm no yeej ib cov yeeb nkab. Niaj hnub no cov loj loj muaj koob meej ntawm hlau-yas yeeb nkab. Specifications tso cai rau cov kev siv ntawm cov khoom no ob leeg nyob rau hauv tsev thiab nyob rau hauv lub chaw ua hauj lwm. Nyob rau hauv lub tsev neeg, cov khoom uas yog siv rau tso underfloor cua kub, sib ntawm cov cua kub thiab kav dej.

Yuav ua li cas yog pes tsawg leeg cov yeeb nkab

Muaj pes tsawg leeg yeeb nkab muaj ib tug txhuas cab kuj txheej thiab daim ntawv thereto nyob rau sab hauv thiab sab nraum lub tuab txheej ntawm polyethylene. Xws li ib tug qauv advantageously tso cai siv zoo qualities ntawm ob tug sib txawv cov ntaub ntawv thiab neutralize tsis zoo.

Polyethylene khaubncaws sab nraud povtseg tiv thaiv txhuas los ntawm corrosion thiab overlays nyob rau sab hauv sab, lub txhuas thiaj li tseem ceeb expansion ntawm polyethylene thiab UV kis, raws li zoo raws li stiffens cov khoom. Cov kev pab cuam lub neej thiab kev cia siab ntawm cov hlab nyob ntawm seb qhov zoo tshaj ntawm cov kua nplaum uas tuav tag nrho khaubncaws sab nraud povtseg. Adhesive eliminates stratification thaum lub sij hawm installation thiab kub ncos.

Yuav kom cov kev xaiv yog rau ib txoj kev koj yuav tsum paub dab tsi yog qhov hom yas kav thiab yuav ua li cas mus thov lawv.

1. Rau cov dej haus. Nyob rau hauv cov ntaub ntawv no nws yog tau siv tej yam khoom, txij li thaum muaj cov tsis muaj kub hloov.
2. Rau cua sov thiab kub cov dej haus. Nws yog tsim nyog them sai sai mus rau lub cim rau nws yuav tsum tau qhia lub hom PE-RT-AL-PE-RT los yog Pex-AL.

Kav hlau. kev yam ntxwv

• Tuam txhab uas muag feem ntau tsim manufacturers yeeb nkab inch 16 hli, 20 hli, 26 hli, 32 hli thiab 40 hli. Tab sis koj yuav nrhiav tau cov khoom ntawm 50 mm thiab 63 hli.
• Muaj pes tsawg leeg yeeb nkab 16 hli ntev 1 'meter' nyhav kwv yees li 100 g
• Cuab yeej khoom siab - 10 atmospheres.
• Qhov siab tshaj plaws khiav hauj lwm kub ntawm cov khoom - 95 ° C. Cov nyiaj pub them nyuag raug - 110 ° C.
• Kav tsim nrog ib lub phab ntsa thickness ntawm 2 hli, 2.5 hli thiab 3 hli.
• phau ntawv dabtsi yog khoov voos kheej-kheej yog 80-550 hli, los ntawm dabtsi yog khoov cuab tam - 45-180 hli.

Qhov tsawg kawg nkaus txoj kab uas hla ntawm yas kav yog permissible xwb nyob rau hauv lub rooj plaub uas ib txwm siab yog khaws cia nyob rau hauv lub central system. Nyob rau hauv kev tsim kho ntawm lub kim heev xov nyob rau hauv ib tug ntiav tsev yog zoo dua rau siv cov khoom nyob rau hauv caliber 32 hli thiab 40 hli.

Lub tsuas tsis zoo, uas yog puas hlab - tus nqi. Nws yog heev siab heev, tshwj xeeb tshaj yog los ntawm txawv teb chaws manufacturers. Txawm li cas los, lawv cov nqi / zoo piv zoo dua yas thiab hlau.

Qhov zoo ntawm cov yas kav

Kav hlau, yam ntxwv hais tias, txawm tus muaj koob meej ntawm cov khoom, lub npe hu tsis tau rau txhua leej txhua tus, muaj ib co kev sib tw zoo:

• durability (kev pab cuam lub neej ntawm cov yeeb nkab yuav tsum tau mus txog li 50 xyoo);
• tsis muaj toxicity;
• kuj mus txhoj puab heev kev kawm;
• lub teeb yuag, uas tso cai rau installation ntawm engineering systems nyob rau hauv ib tug luv luv lub sij hawm, nrog rau tsis muaj ruaj load rau lub hauv paus;
• yooj yim kho;
• tsis ntawm tus me nyuam - yeeb nkab dispensed los ntawm lub 'meter' loj coils uas minimizes pov tseg, ntsuas thiab txiav qhov chaw kawm;
• tsis tuaj kawm ntawv ntawm stray currents ;
• zoo ductility, ua cov yeeb nkab tsis txhob ua txhaum thaum dej uas khov lawm nyob rau hauv lawv;
• Kuv tsis xav tau welding, masking thiab painting;
• High suab nrov yuav txo tau, uas ua rau nws tau tsis txhob siv ntxiv rwb thaiv tsev;
• tsis muaj ib tug linear ncab.

Installation ntawm yas kav

Yuav kom sau high-quality system, nws yog tsim nyog los paub yuav ua li cas mus cuag yas kav. Installation yuav siv cov tshwj xeeb fittings, uas yog muab faib ua ob hom:

• Xovxwm-haum, los yog crimping.
• Compression los yog cov ntsia hlau.

Mounting ntawm yas kav los ntawm xovxwm haum

Kev siv cov xovxwm-haum, ib tug-piece thiab muab ib tug heev robust tsim, uas ua rau nws tau kom tsis txhob txia. Yog li ntawd, thaum lub zais thaiv cov kws txawj qhia kom ua hauj lwm nrog hom kev sib txuas.

Rau nruab cov compression haum, koj yuav tsum Tshuag li on nias lub puab tsaig. Qhov no tshwj xeeb cov cuab tam yuav ua tau phau ntawv los yog hydraulic. Ua ntej koj yuav pib, koj yuav tsum to taub yuav ua li cas mus cuag yas kav nrog kev pab los ntawm ib tug xovxwm haum.

• Yuav pib qhov khoom txiav los ntawm tshwj xeeb txiab.
• End khoom ua calibrator - tshwj xeeb scan uas ib txhij raws tus txiav thiab tshem tawm puab chamfer.
• Pav ca skimmers tiav los ntawm cov txheej ntug ntawm lub raj.
• Nrog rau haum lub tes tsho yog muab tshem tawm thiab ces ua tib zoo ntsuam xyuas kev sib khi rings. Lawv yuav tsum dawb ntawm kev puas tsuaj thiab tsis xws luag. Tom qab xyuas lub tes tsho yog teev nyob rau hauv qhov chaw.
• Connector haum yog tso tag nrho txoj kev mus rau hauv cov yeeb nkab.
• Xovxwm zuam ntsia saum lub liner, thiab ces txuas tus cwj mem tuam.

Re-crimping ntawm tib lub tes tsho yog txwv tsis pub, yog li yog hais tias tus haum tau ntsia tsis zoo, nws yuav tsum tau hloov.

Tshwj xeeb yog tsim xovxwm fittings, thaum ib tug txawv txoj kab uas hla hlau kav yuav tsum tau koom ua ke. Txhawb, fastening cov khoom uas muaj cov tib caliber, hu ua kab. Thiab cov neeg uas txuas seem ntawm txawv diameters, - kev hloov.

Installation ntawm yas yeeb nkab fittings posredstvomkompressionnyh

Qhov no kev twb kev txuas txoj kev yog tshwj xeeb tshaj yog nrov rau nws tus kheej-los ua ke, vim hais tias nws tsis xav mus rau chaw uasi rau tshwj xeeb cov cuab yeej rau nws siv. Ceev ceev yuav ua tau ob pa wrenches. Cov kab sab ntawm lub lag luam yog sawv cev los ntawm cov nram qab no daim ntawv teev:

• Yeeb Nkab, raws li nyob rau hauv cov ntaub ntawv nrog xovxwm haum, yuav tsum xub npaj.
• Shear yog Ameslikas muab tso rau hauv lub noob txiv, ces ferrule.
• Cov khoom no yog tso rau hauv kev twb kev txuas socket.
• Lub compression nplhaib yog coj mus rau lub haum, lub qhov cim tseg txav noob txiv uas overlaps ib lub nplhaib.
• Los ntawm txhais tau tias ntawm ob lub lag luam cov noob txiv yog nruj.

Tsis muaj fittings yuav tsis ua tsis muaj leej twg ntawm lub rooj sib txoos, nrog kev koom tes ntawm yas kav. Tus nqi ntawm cov xovxwm qhov chaw yog ib nyuag ntau dua, kuj yog xws li installation yog xav tau pov tseg, vim hais tias cov kev twb kev txuas yog nonseparable. Thiab qhov no yog tej zaum qhov tseem ceeb drawback ntawm xws fittings, nyob rau hauv cov kev phem ntawm no, lawv ncaj qha hauj lwm lawv ua tau zoo.

Kav hlau, yam ntxwv uas yog heev txaus nyiam, yog ua nce nrov. Niaj hnub no, khoom kab npog lawm 25% ntawm lub lag luam ib tug hlau-khoom, uas yog muab kev koom tes nyob rau hauv ib tug ntau yam ntawm kev tsim kho thiab installation tej hauj lwm.
