Polypropylene hauv cov xwm txheej niaj hnub no tau txais nws qhov chaw. Nws muaj qhov zoo uas ua tau raws li txhua qhov yuav tsum tau ua, yooj yim rau nruab thiab yog tus yam ntxwv los ntawm tus nqi qis.

Yog li ntawd, ntau thiab ntau zaus, cov khoom siv dej, nrog rau cov tshuab cua sov, tau sib sau ua ke siv cov khoom siv no. Polypropylene, fittings los ntawm kev sib txuas los ntawm kev sib txuas, tso cai rau koj los tsim cov qauv monolithic. Nws tsis txawv ntawm cov pob qij txha los ntawm cov kav dej khov.

Txawm li cas los xij, cov khoom siv polypropylene yuav tsum raug xaiv kom raug rau cua sov, dej phwj tuaj, kav dej.

Txoj kev xav ntawm fittings

Txhua qhov system los ntawm kev thauj dej muaj cov kav dej thiab lawv cov kev sib txuas. Cov no yog fittings. Polypropylene nyob rau hauv cov ntaub ntawv no yog suav hais tias yog ib tug zoo xaiv.

Txhais los ntawm lus Askiv, lo lus "fitting" txhais tau tias "mount", "txuas". Lawv yog siv rau folding ncaj kav, ua lem, branching. Nrog lawv cov kev pab, kev hloov ntawm ib txoj kab uas hla mus rau lwm qhov tau ua tiav.

Fittings thiab kav dej rau cov khoom siv xws li polypropylene tuaj yeem ua tauvuam. Qhov no tshwm sim sai heev thaum siv cov hlau soldering nrog nozzles. Nyob rau hauv cov ntaub ntawv no, cov pob qij txha yuav tsis to nrog ib tug high degree ntawm probability.

Cov cuab yeej no yog ib qho zoo tshaj plaws. Niaj hnub no xws li fittings yog xav tau. Polypropylene siv txhua qhov chaw.

Sizes

Cov neeg tsim khoom tsim ntau qhov sib txawv ntawm qhov haum. Qhov no ua rau nws yooj yim los xaiv qhov xav tau ntau yam. Muaj threaded thiab non-threaded kev twb kev txuas. Lawv raug xaiv los ua tus account hauv kev ua haujlwm.

Yog tias nws yog threaded haum, nws tuaj yeem sib cais thiab ruaj khov. Qhov no yuav tsum tau coj mus rau hauv tus account thaum xaiv qhov loj me.

Polypropylene, fittings los ntawm uas feem ntau siv nyob rau hauv sib txawv systems, tso cai rau zus tau tej cov ntau yam sib txawv ntawm nws.

Qhov ntau thiab tsawg yog siv feem ntau nrog ntu ntu ntawm 20, 25, 32, 40 mm. Rau kev npaj cov dej hauv cov tsev ntau-storey, txawm tias qhov loj me xws li 110 hli yog siv.

Txoj kab uas hla yog xam raws qhov ntev ntawm tag nrho cov kab ke. Qhov loj dua, qhov dav dua cov kav dej thiab fittings yuav tsum tau nruab.

Assortment

Lub hom phiaj ntawm cov ntsiab lus ntawm qhov system txawv. Fittings muaj nyob rau hauv ntau yam configuration (polypropylene).

Cov dej phwj tuaj, qhov cua, cua sov lossis dej siv lawv kom tag nrho. Cov kav dej ua los ntawm cov khoom siv no tsis khoov, yog li koj yuav tsum tau siv kev sib txuas hauv txhua rooj plaub. muaj:

  • couplings;
  • kev hloov pauv;
  • fitting;
  • hla;
  • stubs;
  • khaws.

Cov kev sib txuas yuav tso cai rau koj los txuas cov kav dej ntawm tib txoj kab uas hla, thiab kev hloov pauv - ntawm cov hlaws sib txawv. Ib qho haum yuav tsum, yog tias tsim nyog, txhawm rau txuas kev sib txuas lus nrog lub hose hloov tau yooj yim. Crosses yog siv los nqa cov ceg. Lub ntsaws yuav kaw cov yeeb nkab kawg.

Raws li, kev sib hloov tuaj yeem ua tiav siv lub ces kaum. Feem ntau lawv yog 45 thiab 90 degrees.

Marking

Txhawm rau kom tsis txhob hloov cov kav dej hauv lub sijhawm luv, koj yuav tsum xaiv lawv kom raug. Ua li no, xyuam xim rau cov cim.

Cov kav dej thiab fittings ua los ntawm polypropylene rau dej tsis haum rau cua sov. Kev cim yog siv rau txhua qhov chaw.

PN10 belongs rau nyias-walled qhov chaw rau dej txias txog +20 degrees. Ua haujlwm siab - 1 MPa.

PN16 yog tsim los rau cov dej txias txias.

PN20 qhia tias cov khoom tuaj yeem tiv taus cua sov mus txog +80 degrees, thiab siab mus txog 2 MPa.

Rau cov dej kub thiab cua sov, cov khoom cim PN25 yuav tsum tau siv. Lawv muaj peev xwm tuav tau kub txog +95 degrees. Nyob rau tib lub sijhawm, lub siab tso cai hauv lub cev tuaj yeem ncav cuag 2.5 MPa.

Yog tias cov kua dej uas muaj qhov kub siab dua yog muab tso rau hauv cov kav dej rau cov dej txias, lawv yuav pib deform. Yog li ntawd, txawm hais tias tus nqi ntawm cov chav sib txawv ntawm cov kav dej sib txawv heev, koj yuav tsum tau yuav cov khoom uas tsim nyog rau qhov tsis muaj qhov system.fittings thiab kav.

Nyob zoo ib tsoom niam txiv kwv tij neej tsas sawv daws.

Polypropylene fittings rau cua sov, dej dej muaj ntau qhov zoo.

  1. Lub teeb hnyav ua haujlwm yooj yim dua.
  2. Long service life. Hauv cov tshuab cua sov, polypropylene yuav kav ntev txog 25 xyoo, thiab hauv cov kav dej txias sib txuas - 50 xyoo.
  3. Tus nqi qis.
  4. Quick installation.
  5. Aesthetic tsos.

Txhua yam zoo li no ua rau cov khoom nrov heev. Nws cov koob meej yog nce yuav luag txhua hnub. Fittings yog resistant rau corrosion thiab chemical influences. Lawv tsis tso cov txiv qaub tso tseg, tsis txhob yug cov kab mob.

Flaws

Polypropylene fittings rau cov kav dej thiab lwm cov tshuab muaj ntau yam tsis zoo. Lawv suav nrog rigidity zoo. Lawv tsis tuaj yeem khoov. Yog li ntawd, thaum lub sij hawm installation, yuav tsum muaj ib tug loj tus naj npawb ntawm kev sib txuas.

Qhov tsis zoo kuj suav nrog qhov yuav tsum tau siv cov cuab yeej tshwj xeeb. Nws yuav tsum tau yuav los ua ke.

Ua li no, koj yuav tsum tau yuav cov hlau tshwj xeeb uas muaj cov nozzles ntawm txoj kab uas hla. Nws yog ib qho tsim nyog los txiav cov kav dej nrog txiab tshwj xeeb. Tsis tas li ntawd, lub trimmer, ib daim kab xev ntsuas, ib lub cim tau npaj ua ntej.

Rau kev sib dhos, qhov kub ntawm 240-260 degrees yog teem rau hauv hluav taws xob soldering hlau. Siv lub trimmer, txheej nruab nrab ntawm cov ntawv ci raug tshem tawm ntawm cov yeeb nkab los ntawm 2 hli.

Ib lub yeeb nkab tau muab tso rau ntawm ib sab ntawm lub taub hau ntawm lub taub hau, thiab muab tso rau ntawm lwm qhov. Lub sijhawm cua sov yog khaws cia rau 3-5 s. Lawv raug muab tshem tawm ib txhij thiab cov yeeb nkab txuas nrog qhov haum. Cia lub ntsiab kom txias thiab xyuas qhov sib koom ua ke. Qhov no yog ib qho yooj yim thiab yooj yim installation, siv tau txawm rau beginners.

Tau paub txog cov khoom siv xws li polypropylene, fittings los ntawm qhov xav tau zoo niaj hnub no, koj tuaj yeem sib sau ua ke ntau hom tshuab. Tom qab xaiv tag nrho cov ntsiab lus kom raug thiab sib sau ua ke kom raug, koj tuaj yeem suav nrog lub neej ua haujlwm ntev ntawm lub system. Raws li ib qho ntawm cov khoom siv feem ntau siv, polypropylene muaj ntau yam zoo. Yooj yim ntawm installation, durability thiab tus nqi qis nce qhov kev thov rau fittings los ntawm nws.
