Thaum tso dej thiab cua sov tshuab, fittings yuav tsum tau siv, uas tau nthuav tawm hnub no hauv ntau hom. Lawv siv los txuas ntawm cov ntsiab lus tig, ceg thiab kev hloov pauv. Cov ntsiab lus no yog qhov tseem ceeb thaum txuas cov kav dej ntawm cov kab sib txawv. Cov nodes tuaj yeem npaj rau cov kav dej polypropylene lossis cov tshuab hlau-yas.
Kev faib tawm ntawm polypropylene fittings
Yog tias koj xav tau qhov haum, lub cuab yeej no yog dab tsi, koj yuav tsum paub. Cov ntsiab lus no tso cai rau cov tshuab tso rau hauv qhov ntev, tso cai rau kev hloov pauv thiab hloov pauv. Thaum nws los txog rau polypropylene fittings, lawv tuaj yeem raug cais raws li lawv cov duab. Ntau yam ntawm cov ntsiab lus no tuaj yeem tsim cov ces kaum, ntawm lawv yuav tsum tau hais txog:
- clutch;
- pob;
- tee;
- hloov;
- adapter;
- "American";
- collector;
- bypass.
Cov kav dej txuas nrog siv fittings, lawv cov khoom yuav tsum yogtib yam li cov kav dej lawv tus kheej. Yog tias lub kaw lus muaj fiberglass-reinforced mains, ces lwm yam khoom siv tsis tau.
Polypropylene fittings ntxiv nrog fiberglass kuj tseem xav tau. Ib qho kev zam yog kev sib txuas ntawm cov khoom siv polypropylene nrog hlau lossis lwm yam khoom siv. Hauv qhov no, koj tuaj yeem siv American hom threaded element.
cais raws qhov chaw
PVC fittings kuj tseem tuaj yeem faib los ntawm qhov chaw. Hauv qhov no, nws yog qhov yuav tsum tau ua kom pom cov fittings:
- ncig.
- T-shaped.
- Y-zoo li tus.
Fittings tuaj yeem raug cais raws li hom kev sib txuas, lawv tuaj yeem raug welded lossis compression. Lub crimp version yog muag nyob rau hauv ib tug npaj-ua khoom siv, tsis tas yuav tsum tau ntxiv los ua ke. Yog hais tias peb piv nws nrog ib tug welded sib koom, ces tus thawj muaj qhov zoo. Cov txiaj ntsig tseem ceeb yog:
- easy installation;
- tsis xav tau vuam;
- muaj peev xwm ntawm kev teeb tsa hauv txhua qhov huab cua, vim tias cov khoom siv polypropylene crimp tsis ntshai ntawm qhov kub tsis zoo;
- tsis muaj kev txawj ntse los sib sau ua ke compression fittings.
Yuav ua li cas xaiv welded txuas fittings
Ib qho haum yog muag hnub no hauv ntau hom. Dab tsi yog thiab qhov twg siv lub ntsiab lus no, koj tuaj yeem paub yog tias koj nyeemtsab xov xwm. Lub luag haujlwm ntawm ib qho yooj yim fittings yog ib qho kev sib txuas, uas yog tsim nyog los txuas ob qhov kawg ntawm cov kav dej. Nws tuaj yeem siv rau vuam siv zog thiab cov kav dej zoo tib yam.
Cov haujlwm no yog ua los ntawm kev siv lub qhov (socket method). Tab sis ntawm cov khoom zoo li no, ib tus tuaj yeem paub qhov txawv ntawm cov ces kaum, manifolds, thiab tees. Thaum xaiv ib lub tee, koj yuav tsum tau them sai sai rau qhov tseeb tias nws tuaj yeem hloov pauv lossis yooj yim. Hauv thawj kis, koj tuaj yeem hloov mus rau lwm txoj kab uas hla.
lus qhia ntxiv rau kev xaiv
Yog tias tsim nyog los tso cov dej kub lossis dej txias, koj yuav tsum xaiv cov khoom siv uas tuaj yeem siv los txuas ob peb cov khoom siv rau qhov cua sov. Qee lub sij hawm nws tau ntxiv nrog pob li qub, uas ntseeg tau los tiv thaiv corrosion.
Thaum tus tswv tsev xav tau qhov haum, nws yog dab tsi thiab hom twg, nws yuav tsum paub tseeb. Piv txwv li, txhawm rau hloov cov kav dej 90 °, koj xav tau ib lub ces kaum. Nws txoj kev vuam yog ua los ntawm txoj kev socket, cov haujlwm no suav nrog cua sov cov ntsiab lus thiab txuas lawv los ntawm kev ntxig ib qho mus rau lwm qhov.
Kev faib cov khoom siv hlau
steel fittings tuaj yeem faib raws li lub hom phiaj, lawv tau nthuav tawm:
- couplings;
- tees;
- fittings;
- adapters;
- plugs.
Raws li qhov chaw siv, lawv tuaj yeem muab faib ua nruab nrab thiab sib txuas. Thaum nws los txog rau kev sib txuas cov kav dejntawm tib txoj kab uas hla, ces cov pob qij txha ncaj yuav tsum tau siv, txwv tsis pub koj yuav tsum tau khaws cov khoom hloov pauv. Lawv yog threaded.
Raws li txoj kev sib txuas, steel fittings yuav tsum muab faib ua:
- compression;
- nias fittings;
- push fittings;
- crimp;
- xov.
Yog tias koj xav tau qhov haum, qhov tsim no yog dab tsi, koj yuav tsum paub tseeb. Piv txwv li, threaded qhov chaw yog ib txwm siv ntawm kev sib txuas cov khoom. Tab sis compression fittings yog qhov nrov tshaj plaws niaj hnub no, vim tias lawv yooj yim rau nruab. Lawv tuaj yeem siv los txuas cov kav dej ntawm cov khoom sib txawv. Axial fittings yog ib txoj kev thoob ntiaj teb, uas tuaj yeem siv rau ntau hom kav dej.
Kev qhia xaiv cov xov fittings
xov fittings tuaj yeem ua los ntawm cov khoom sib txawv. Yog hais tias nws yog tooj dag, ces nyob rau hauv pem hauv ntej ntawm koj yog cov ntsiab lus uas niaj hnub no. Lub xub ntiag ntawm lub nplhaib clamping muab nruj rau txhua qhov kev sib txuas. Yog tias koj xav ua kom tiav cov khoom tiv thaiv corrosion, ces koj yuav tsum xaiv cov khoom siv coated, uas yog qhov tsim nyog thaum ua haujlwm nrog cov kav dej.
Yog tias koj xav yuav ib yam khoom ntawm tus nqi pheej yig, ces cov khoom siv tooj liab yuav tsum nyiam dua. Lawv tsis xeb thiab ua haujlwm ntev. Yog tias koj xav hloov cov kev taw qhia ntawm qhov ntws ntawm qhov nruab nrab hauv cov kav dej, ces koj yuav tsum yuav cov khoom siv hluav taws xob threaded. Tab sis los tsim ib qho ntsiab lusfaib ib kwj mus rau ob peb, tee yuav nyiam.
Yog tias tsim nyog los tsim kev sib txuas ntawm ob lub kav dej rau hauv ib qho system, kev sib txuas yuav tsum tau siv, cov khoom no yog qhov zoo tshaj plaws rau kev npaj cov kav dej los ntawm cov khoom sib txawv. Hauv qhov no, koj tuaj yeem txuas cov yeeb nkab yas nrog ib qho tooj liab. Fittings rau cov kav dej tooj liab kuj tuaj yeem ua los ntawm cov khoom zoo sib xws. Piv txwv li, plugs muaj peev xwm kaw lub kaw lus thiab thaiv qhov kawg ntawm cov yeeb nkab. Qee lub sij hawm qhov no tsis yog tsuas yog siv cov ntsiab lus ua haujlwm xwb, tab sis kuj yog cov khoom siv zoo nkauj.
Thaum xaiv fittings rau cov kav dej tooj liab, koj yuav tsum nyiam cov khoom uas ua los ntawm tib cov khoom, vim lawv yog cov ruaj khov tshaj plaws, yooj yim rau nruab thiab txhim khu kev qha. Txhawm rau txhim kho lawv cov kev ua tau zoo, lawv tau coated nrog cov ntaub ntawv tshwj xeeb, ntawm lawv:
- nickel;
- chrome;
- zinc.
Fittings price
