PEX Cov Cuab Yeej

PEX yeeb nkab cov cuab yeej yog cov cuab yeej tshwj xeeb uas siv los txhim kho thiab kho cov kab txuas txuas txuas nrog polyethylene (PEX) kav. Cov cuab yeej no yog tsim los txiav, crimp, khoov, thiab txuas PEX kav dej sai thiab ua tau zoo. PEX yeeb nkab cov cuab yeej suav nrog cov yeeb nkab cutters, cov cuab yeej crimping, cov cuab yeej khoov, cov cuab yeej nthuav dav, thiab li qub thiab fittings. Cov cuab yeej no feem ntau yog siv los ntawm cov kav dej, HVAC cov kws tshaj lij, thiab cov neeg nyiam DIY rau ntau yam kev siv, xws li cov kav dej, cua sov, thiab cua txias.

Kev txheeb xyuas qhov sib txawv ntawm Pex Tubing
Muaj peb hom PEX tubing muaj rau cov kav dej: PEX A, PEX B, thiab PEX C. Qhov sib txawv ntawm peb cov ntaub ntawv no yog cov txheej txheem uas cov chaw tsim khoom siv los tsim lawv. PEX, tau kawg, yog lub sijhawm kev lag luam rau kev sib txuas ntawm polyethylene. Cov txheej txheem uas lub chaw tsim khoom ua qhov sib txuas yog qhov qhia tias hom PEX (A, B, lossis C) yog dab tsi.
Qhov sib txawv ntawm peb tsis tas yuav yog qib lossis kev ua tau zoo. PEX A tsis yog qhov zoo dua li PEX C. Qhov sib txawv ntawm PEX pab cov kav dej txiav txim siab seb hom kev haum rau siv thiab cov yam ntxwv ntawm lub raj yuav muaj dab tsi.
Feem ntau, hom PEX tus kav dej siv feem ntau los ntawm tus kheej nyiam. Vim tias tag nrho peb hom PEX tubing yuav tsum ua tau raws li ASTM F876 thiab NSF / ANSI / CAN 61 tus qauv, cov kav dej tuaj yeem tso siab tau tias lawv cov kev xaiv yuav yog raws li txoj cai. Koj yuav pom qhov sib txawv me me hauv qhov ntom ntom, tawg qib siab thiab khoov lub vojvoog ntawm PEX yeeb nkab hom, tab sis lawv tsis tsim nyog.
Tsis muaj delving deb dhau mus rau cov ntaub ntawv xov xwm zoo heev txog cov txheej txheem siv los ua cov hom sib txawv ntawm PEX, ntawm no yog qhov nrawm nrawm ntawm cov yam ntxwv tseem ceeb tshaj plaws ntawm txhua hom, thiab vim li cas koj thiaj li xav xaiv ib qho ntawm lwm tus.

●Pex A
Yooj yim tshaj plaws
Nws muaj "nco" uas txhais tau tias nws thim rov qab mus rau qhov loj me
Nws muaj qhov zoo tshaj plaws "kink" tsis kam
Yuav tsum tau siv thaum ua kev sib txuas ntawm qhov txias txias (CEP).
Feem ntau ntau yam, ntau txoj hauv kev los ua ib qho kev sib koom ua ke (txias nthuav dav, crimp nplhaib, pinch clamp, thawb-haum, compression lossis twist & xauv)
●Pex B
Feem ntau siv rau crimp hom fittings vim nws yog qhov kev xaiv pheej yig tshaj plaws
Ntau txoj hauv kev los ua ib qho kev sib koom ua ke (crimp nplhaib, pinch clamp, laub-fit, compression lossis twist & xauv)
Kev nruj dua li PEX A & PEX C
Tsawg "kink" tsis kam
●Pex C
Siv tib txoj kev sib txuas xws li PEX B sib koom ua ke (crimp nplhaib, pinch clamp, laub-fit, compression lossis twist & xauv)
Yam tsawg kawg nkaus ntawm PEX piping siv
Ib qho nruj dua li PEX A, qee lub npe tau ua rau muaj kev txhim kho ntawm cov kab nrib pleb
Tsawg "kink" tsis kam tshaj PEX A
Yog tias koj tab tom pib los ntawm kos rau ntawm txoj haujlwm kav dej tshiab, koj tuaj yeem xaiv hom PEX koj xav siv raws li qee qhov txiaj ntsig saum toj no. Tau kawg, yam uas koj lub khw muag khoom kav dej hauv zos nqa yuav cuam tshuam rau koj qhov kev txiav txim siab.
Yog tias koj tab tom kho rau PEX system uas twb muaj lawm, koj yuav xav txheeb xyuas seb hom PEX tam sim no siv li cas thiaj li tuaj yeem phim nws. Tsuas yog saib ib ntu ntawm cov kav dej uas tsis zoo, tshwj xeeb tshaj yog nyob ib puag ncig cov pob qij txha. Yog tias lawv yog cov khoom siv txias txias, koj paub tias PEX A tau siv los ntawm cov yas PEX-A Ntiv nplhaib / lub tes tsho. Yog hais tias lawv yog fittings ntawm ze li lwm yam, koj yuav paub tias nws yog feem ntau yuav PEX B los yog tej zaum PEX C, thiab koj yuav tau raws li.

Yuav Ua Li Cas Txiav Txim Qhov Loj ntawm Koj Pex Piping
Kev txiav txim siab qhov loj ntawm koj lub PEX yog qhov yooj yim heev, nws tau luam tawm nyob rau sab ntawm PEX yeeb nkab.
Thaum lub tshuab luam ntawv tau ploj mus, tsis muaj kev txhawj xeeb. Sab nraud txoj kab uas hla tuaj yeem ntsuas tau siv lub vernier caliper.
Thaum PEX nyob ntawm 3/8 "mus rau 1", qhov ntau thiab tsawg uas koj yuav pom hauv cov ntawv thov hauv vaj tse yog 1/2 "thiab 3/4" thaum 1" feem ntau siv rau cov kab noj loj. Feem ntau, peb xav kom sib piv dab tsi twb muaj nyob rau hauv koj qhov system.
Nco ntsoov txog kev hloov diameters:
Hauv cov ntawv thov feem ntau, nws yuav yooj yim dua nrog tib txoj kab uas hla PEX cov yeeb nkab siv yav dhau los hauv koj lub cev. Txawm li cas los xij, yog tias koj tab tom ntsib teeb meem ntws los yog lub siab tsis zoo nws yuav ua rau muaj txiaj ntsig zoo rau txoj kab uas hla. Ib qho yuav tsum paub tias PEX piping muaj qhov me me hauv txoj kab uas hla tshaj li cov yeeb nkab tooj liab ntawm tib lub npe loj.

Sib piv cov hom Pex Connections muaj
Tam sim no koj tau txheeb xyuas hom PEX koj siv, peb tuaj yeem pib tshuaj xyuas seb hom haum twg yuav ua rau muaj txiaj ntsig zoo rau koj cov kev xav tau.

Sib piv cov khoom ntawm ntau yam fittings
PEX fittings feem ntau yog tsim los ntawm ib qho ntawm peb hom khoom sib txawv: Yas, tooj dag, lossis Stainless hlau. Xwb, lub laub haum haum siv cov khoom sib xyaw ua ke. Raws li koj tuaj yeem xav, muaj qhov zoo thiab qhov tsis zoo rau txhua qhov kev xaiv uas peb yuav piav qhia luv luv hauv qab no.
●Yas
Yog tias tus nqi yog koj qhov tseem ceeb tshaj plaws, nws tsis tuaj yeem tuav cov yas fittings hauv PEX system. Cov fittings no kuj zoo kawg nkaus tiv taus corrosion.
Kev lag luam tawm yog tias hom crimp PEX lawv muaj cov phab ntsa tuab dua li cov hlau fittings, txij li qhov haum mus rau hauv cov yeeb nkab PEX, cov dej ntws tuaj yeem raug txwv hnyav heev. Ib tug puv tes ntawm cov yas fittings yuav tsis ua ib qho tseem ceeb sib txawv, tab sis nyob rau hauv lub chav kawm ntawm ib tug tag nrho cov system, qhov poob nyob rau hauv txaus thiab los yog siab yuav yeej ntxiv.
Nco ntsoov tias cov yas Cold Expansion PEX (CEP) fittings muaj qhov zoo sib xws hauv cov kab uas hla rau cov hlau txias nthuav dav PEX fittings thiab tsis cuam tshuam rau qhov ntws.
●tooj dag
Hlau crimp fittings, xws li tooj dag, daws qhov teeb meem ntawm thickness head-on. Vim tias cov hlau muaj zog dua li cov yas, cov hlau nyias nyias tuaj yeem siv tau thiab tseem muaj zog tshaj lub zog ntawm cov yas haum. Lub zog tseem ceeb npaum li cas? Qhov no yuav yog qhov sib txawv nyob ntawm koj qhov kev siv tshwj xeeb, tab sis rau kev tiv thaiv cov khoom xws li dej rauj (shockwaves xa los ntawm koj lub kav dej thaum lub valve raug kaw sai dhau) lossis kev tsim khoom tsis xws luag, hlau yog qhov kev xaiv zoo tshaj.
Qhov loj tshaj plaws poob nrog tooj dag yog nws susceptibility rau corrosion. Tshwj xeeb tshaj yog vim hais tias PEX nws tus kheej tsis corrode (feem ntau), tsuas muaj ib qho chaw uas corrosion yuav tsom: koj fittings. Cov tooj dag yog qhov cuam tshuam rau dezincification, thiab hauv qee qhov dej nws tau paub tias yuav ua rau muaj teeb meem loj uas ua rau cov khoom puas tsuaj vim yog cov khoom tawg los yog tawg. Yuav ua li cas koj yuav caij nplooj ntoos hlav xau? Qhov ntawd tag nrho nyob ntawm qhov zoo ntawm koj cov dej thiab dab tsi hauv nws. Muaj cov sijhawm xa cov qauv ntawm koj cov dej tawm mus rau chav kuaj sim, tab sis rau tus neeg nruab nrab, qhov no muaj kev koom tes ntau dua li lawv xav tau.
●Stainless hlau
Thaum koj xav tau ib yam khoom uas muaj corrosion-resistant yas thiab lub zog uas yog superior rau tooj dag, stainless hlau fittings yog los ntawm tag nrho cov txhais tau tias qhov zoo tshaj plaws kev xaiv muaj. Nrog lub zog uas tau raug sim rau ob zaug lub zog ntawm tooj dag, stainless hlau haum tiag tiag yog qhov zoo tshaj plaws ntawm ob lub ntiaj teb, tsis muaj lwm yam haum rau kev ua lag luam uas tuaj yeem phim nws qhov tshwj xeeb-rau-feature.
Qhov kev txwv rau cov hlau tsis muaj steel fittings (yog tias koj tuaj yeem hu rau nws) yog qhov txias expansion fittings tsis muaj, lawv tsuas muaj nyob rau hauv Crimp PEX fittings (ASTM-F1807) fastened los ntawm tooj liab crimp rings los yog SS pinch clamps. Boshart Industries yog thawj-rau-ua lag luam nrog Stainless Steel kuj txhais tau tias koj tsuas tuaj yeem pom cov khoom no nrog peb.

Cov cuab yeej los ua cov kev sib txuas no
Yog tias koj tshiab rau cov kav dej, kev nqis peev hauv cov cuab yeej los pib nrog ib qho ntawm cov tshuab no yog lwm qhov yuav tsum tau xav txog. Yog tias koj tsuas yog ua ib qho me me, ib qho kev ua haujlwm lossis kho, cov cuab yeej siv phau ntawv lossis lub tshuab haum uas tsis xav tau cov cuab yeej tshwj xeeb yog qhov koj xaiv zoo tshaj. Tej zaum nws yuav tsis muaj txiaj ntsig rau kev nqis peev hauv lub tshuab hluav taws xob ua tiav uas yuav ua rau lub txhab nyiaj tawg. Tab sis, yog tias koj tab tom npaj ua cov kav dej niaj hnub, nws yuav muaj txiaj ntsig rau koj los saib cov cuab yeej tshwj xeeb uas yuav txo tau lub sijhawm teeb tsa thiab siv yooj yim dua.
