Brass Compression Fittings vs Threaded Fittings: Qhov kev sib txuas zoo dua?

Xaiv hom kev sib txuas yog ib qho tseem ceeb xws li xaiv cov khoom haum nws tus kheej. Thaum koj tab tom nrhiav cov yeeb nkab tooj dag fittings rau qhov project kav dej, ib qho HVAC installation, los yog muaj kua dej system, qhov kev txiav txim siab ntawm compression thiab threaded kev sib txuas yuav cuam tshuam rau txhua yam los ntawm kev teeb tsa lub sijhawm mus rau cov nqi tu mus ntev.

Qee tus neeg yuav khoom xav tias compression fittings yog "tsis muaj zog" vim tias lawv tsis cia siab rau cov xov. Lwm tus ntseeg tias threaded tooj dag fittings yeej ib txwm muaj kev nyab xeeb thawj koom ruam rau kev ua haujlwm siab. Ob qhov kev xav tau tsim nyog saib ze dua.

Kab lus no sib piv tooj dag compression fittings vs threaded fittings nyob rau hauv lub installation, sealing kev ua tau zoo, muaj peev xwm siab, kev saib xyuas, thiab cov ntawv thov hauv ntiaj teb tiag tiag - yog li koj tuaj yeem phim txoj kev sib txuas mus rau txoj haujlwm raug.

Brass compression haum thiab threaded tooj dag haum

Dab tsi yog Brass Compression Fittings?

A tooj dag compression haum tsim ib lub foob los ntawm mechanically compressing ib lub nplhaib hlau mos-hu ua ferrule los yog txiv ntseej-tawm tsam sab nrauv ntawm cov yeeb nkab. Tsis muaj soldering, tsis muaj vuam, tsis muaj xov sealant yuav tsum tau. Cov yeeb nkab tsuas yog swb mus rau hauv lub cev haum, thiab zawm cov txiv ntoo deforms lub ferrule nyob ib ncig ntawm cov yeeb nkab, tuav nws ruaj ntseg thiab tsim ib qho dej sib koom ua ke.

Lub compression haum kev twb kev txuas yog elegant nyob rau hauv nws simplicity. Peb lub luag haujlwm ua txhua yam haujlwm:

CheebtsamMuaj nuj nqi
Compression txiv ntooTightens lub rooj sib txoos
Ferrule / Txiv ntseejDeforms los tsim lub zog sealing
Haum lub cevTsev cov yeeb nkab thiab muab sealing nto

Lub hauv paus ntsiab lus ntawm kev ua haujlwm ua raws li ib ntus ncaj qha: Cov yeeb nkab ntxig → ferrule swb rau → txiv ntseej nruj → ferrule compressed → foob tsim. Lub foob yog los ntawm lub ferrule lub deformation, tsis yog los ntawm cov xov. Qhov kev sib txawv no tseem ceeb vim tias nws txhais tau tias kev sib khi zoo nyob ntawm kev sib dhos kom raug es tsis yog xov xwm lossis daim ntawv thov sealant.

Brass compression fittings yog tus qauv xaiv rau tooj liab, tooj dag, thiab cov khoom siv yas hauv cov kav dej hauv tsev thiab lub teeb lag luam. Lawv raug ntsuas rau qhov siab txog li 200-300 psi hauv kev teeb tsa thiab kub txog li 250 ° F (121°C).

Dab tsi yog Threaded Brass Fittings?

Threaded tooj dag fittings cia siab rau interlocking txiv neej thiab poj niam threads los tsim ib qho kev sib koom ua ke. Raws li cov tapered threads koom thiab zawm, cov hlau nto wedge ua ke, thiab ib lub xov sealant-PTFE daim kab xev los yog yeeb nkab dope-sau lub microscopic khoob kom tiav lub foob.

Qhov tseem ceeb sib txawv los ntawm compression fittings: cov threads lawv tus kheej muab ob qho tib si lub zog txhua yam thiab thawj sealing nto. Yog cov threads puas, hla txoj xov, los yog kaw tsis raug, kev sib txuas yuav xau - txawm tias koj ua kom nruj npaum li cas.

Xov xwm tseem ceeb heev ntawm no. Ob tug tseem ceeb systems yog:

Xov HomTxujLub kaum sab xisThawj Thaj Tsam
NPTANSI / ASME B1.20.160°North America
BSPT / BSPPISO 228 / ISO 755°Teb chaws Europe, Asia, thoob ntiaj teb

NPT threads siv lub kaum sab xis 60 ° thiab 1.7898 ° taper ib sab, ua rau cov xov sib txuas ua ke thaum lawv nruj. BSP threads siv lub kaum sab xis 55 ° thiab tej zaum yuav sib npaug (BSPP) los yog tapered (BSPT).

Rau kev sib piv sib sib zog nqus ntawm ob lub tshuab no, saib peb phau ntawv qhia rau NPT vs BSP Xov.

Threaded tooj dag fittings yog cov khoom siv tshaj plaws hauv cov pa roj thiab dej hauv tsev. High-pressure forged tooj dag threaded fittings tuaj yeem tswj qhov siab txog 3,000-6,000 psi nyob ntawm tus qauv thiab qhov loj.

Lub rooj no ib leeg teb cov lus nug feem ntau cov neeg yuav khoom nug: qhov kev sib txuas zoo dua? Cov lus teb ncaj ncees yog tias tsis yog qhov zoo tshaj plaws hauv ntiaj teb - txhua tus yeej hauv cov xwm txheej tshwj xeeb.

Kev teeb tsa: Qhov twg yog qhov yooj yim dua?

Compression Installation Cov kauj ruam

  1. Txiav cov yeeb nkab squarely thiab deburr kawg.
  2. Xaub lub txiv ntoo compression, ces lub ferrule, rau lub cev.
  3. Ntxig cov yeeb nkab tag nrho rau hauv lub cev haum.
  4. Tighten lub txiv ntseej ntawm tes, ces ua kom tiav nrog ib tug ciaj ntswj-feem ntau 1 mus rau 1½ tig dhau los ntiv tes nruj.
  5. Tshawb xyuas cov dej xau hauv qhov system siab.

Tag nrho cov txheej txheem yuav siv sijhawm feeb. Tsis muaj cua sov, tsis muaj tshuaj, tsis muaj xov npaj. Qhov no yog vim li cas compression fittings dominate DIY kho thiab chaw ua hauj lwm.

Threaded Installation cov kauj ruam

  1. Ntxuav thiab tshuaj xyuas cov xov.
  2. Siv PTFE daim kab xev nyob rau hauv cov kev taw qhia ntawm xov rotation (2- 3 qhwv rau me me fittings).
  3. Tighten tus txiv neej rau hauv poj niam.
  4. Cov ciaj ntswj-tighten mus rau qhov tsim nyog kev sib koom ua ke qhov tob - tsawg dhau thiab nws ntws, ntau dhau thiab koj pheej hmoo tawg qhov haum.
  5. Kuaj nyob rau hauv siab.

Hom kev ua tsis tiav ntawm no yog kev zam txim tsawg dua. Overtightening ib tug tapered xov tuaj yeem deform lub cev haum los yog ua rau muaj kev ntxhov siab tawg, tshwj xeeb tshaj yog nyob rau hauv cov tooj dag me me. Hauv qab-tightening tawm qhov sib txawv uas sealant ib leeg yuav tsis txuas.

Sealing Performance thiab Kev Tiv Thaiv Leak

Compression fittings foob ​​los ntawm deformation. Lub ferrule conforms rau cov yeeb nkab nto, tsim kom muaj kev sib txuas sib txuas uas ua tau zoo dua qub thaum lub siab sab hauv nce ntxiv-lub siab zoo li nthuav dav lub raj tiv thaiv lub ferrule. Hom tsis ua haujlwm feem ntau tsis yog sealing tsis muaj zog tab sis kev teeb tsa yuam kev: over-tightening deforms lub ferrule tshaj rov qab, los yog nyob rau hauv-tightening nplooj tsis txaus compression.

Threaded fittings foob ​​los ntawm interlocking threads thiab sealant. Lub sealant sau qhov sib txawv helical ntawm txiv neej thiab poj niam xov. Qhov teeb meem yog tias cov xov tapered ib txwm muab txoj hauv kev uas muaj peev xwm xau - lub hauv paus ntawm cov xov tsis zoo kawg nkaus kaw yam tsis muaj sealant. Xov puas, sealant tsis txaus, los yog incompatible sealant rau hom kua dej tag nrho ua rau xau.

FAQ

Q1: Dab tsi yog qhov txawv ntawm tooj dag compression fittings thiab threaded fittings?

A: Brass compression fittings foob los ntawm compressing lub ferrule nyob ib ncig ntawm cov yeeb nkab sab nrauv; threaded fittings foob los ntawm interlocking tapered threads nrog sealant. Compression yog ceev rau nruab thiab yooj yim rau disassemble. Threaded ua haujlwm siab dua thiab nyiam rau kev siv roj thiab kev lag luam.

Q2: Yog tooj dag compression fittings txhim khu kev qha?

A: Yog lawm, thaum ntsia kom raug. Qhov teeb meem kev ntseeg siab tshaj plaws yog over-tightening, uas deforms lub ferrule thiab tuaj yeem ua rau xau. Ua kom zoo compression fittings ntawm huv, round yeeb nkab muab kev pabcuam txhim khu kev qha hauv cov dej thiab cov kua dej tsis zoo.

Q3: Yog threaded tooj dag fittings muaj zog tshaj compression fittings?

A: Threaded tooj dag fittings feem ntau muaj kev ntsuas siab dua - txog li 3,000 psi los yog ntau tshaj nyob rau hauv forged configurations-piv rau 200-300 psi rau raug compression fittings. Txawm li cas los, “muaj zog dua” nyob ntawm cov khoom tshwj xeeb thiab daim ntawv thov. Rau qhov chaw muaj kev vibration siab, threaded kev sib txuas kuj tiv taus loosening zoo dua.

Q4: Cov compression fittings tuaj yeem rov qab siv dua?

A: Lub cev haum thiab cov txiv ntoo tuaj yeem siv tau ntau zaus, tab sis lub ferrule feem ntau yuav tsum tau hloov vim nws twb tau deformed kom phim cov yeeb nkab tshwj xeeb. Reusing ib tug deformed ferrule rau ntawm ib tug sib txawv cov yeeb nkab seem yog ib qho ua rau kom muaj pa. Hloov ferrules yog dav muaj thiab pheej yig.

Q5: Qhov twg haum zoo dua rau cov kav dej?

A: Rau cov kab dej hauv tsev, compression feem ntau yog qhov kev xaiv zoo-ceev, huv si, thiab kho tsis tau cov cuab yeej tshwj xeeb. Rau roj kab, high-pressure systems, los yog kev sib txuas uas yuav nyob twj ywm tsis muaj kev cuam tshuam rau ntau xyoo lawm, threaded fittings yog tus qauv. Cov lus teb yog nyob ntawm lub siab, nruab nrab, thiab kev cia siab rau kev kho.
