Taw qhia rau coupling
Nyob rau hauv lub tshav pob ntawm cov yeeb nkab fittings, lo lus "coupling" sawv cev rau ib tug yeeb nkab sib txuas los yog connector, uas yog ib tug tseem ceeb tivthaiv siv los txuas ob kav dej.
Kev tsim qauv ntawm cov yeeb nkab fittings no aims kom ua tiav qhov ruaj khov thiab kaw kev sib txuas ntawm cov kav dej, kom ntseeg tau tias du thiab xau tsis pub xa cov kua dej (xws li dej, roj, lossis tshuaj) hauv cov kav dej.
Muaj ntau hom kev sib txuas, uas tuaj yeem muab faib ua ntau hom raws li lawv cov qauv, cov ntaub ntawv, thiab cov ntawv thov scenarios. Piv txwv li, raws li txoj kev sib txuas, nws tuaj yeem muab faib ua threaded kev twb kev txuas, flange kev twb kev txuas, welded kev twb kev txuas, thiab clamp kev twb kev txuas, thiab lwm yam; Raws li kev faib cov khoom siv, muaj cov pob qij txha hlau (xws li stainless hlau, tooj liab, hlau, thiab lwm yam), cov pob qij txha yas (xws li PVC, PE, thiab lwm yam), thiab cov khoom sib xyaw ua ke. Txhua hom kev sib txuas muaj nws qhov tshwj xeeb zoo thiab muaj peev xwm ntawm daim ntawv thov.
Nyob rau hauv cov nqe lus ntawm cov txheej txheem kev, couplings tsim ib tug nruj mechanical kev twb kev txuas nrog cov kav dej los ntawm lawv cov qauv tsim, xws li threads, flanges, los yog clamps. Nyob rau tib lub sijhawm, qhov sib koom ua ke feem ntau yog nruab nrog cov khoom sib khi hauv, xws li roj hmab sealing rings lossis hlau sealing rings, kom ntseeg tau tias kev sib khi ntawm kev sib txuas thiab tiv thaiv cov kua dej tawm. Tsis tas li ntawd, qee qhov kev sib txuas ntawm cov yeeb nkab siab kuj tseem muaj cov yam ntxwv xws li kev kub siab thiab kev tiv thaiv corrosion kom hloov mus rau qhov chaw ua haujlwm hnyav.
Nyob rau hauv cov nqe lus ntawm daim ntawv thov scenarios, couplings yog dav siv nyob rau hauv ntau yam pipeline systems, xws li cov khoom siv dej thiab cov kav dej, HVAC systems, petrochemical systems, zaub mov, thiab lwm yam. Nyob rau hauv cov tshuab no, cov yeeb nkab txuas tsis yog tsuas yog siv los txuas cov kav dej, tab sis kuj tseem siv rau cov kav xa dej, hloov cov kav dej, lossis kho cov kav dej ntev. Piv txwv li, nyob rau hauv cov dej thiab cov kav dej, cov yeeb nkab txuas tau yooj yim txuas cov kav dej ntawm cov kab sib txawv lossis cov khoom siv los tsim cov kav dej ua tiav; Hauv cov txheej txheem petrochemical, cov yeeb nkab sib txuas tuaj yeem tiv taus kev yaig ntawm kev kub siab thiab cov kua dej corrosive, ua kom muaj kev nyab xeeb ntawm kev ua haujlwm.
Raws li cov qauv kev lag luam, kev tsim khoom thiab kev siv cov couplings yuav tsum ua raws li cov txheej txheem thoob ntiaj teb thiab cov qauv hauv tsev, xws li ISO, DIN, ANSI, thiab lwm yam. Cov qauv no qhia cov kev xav tau ntawm qhov loj, cov khoom siv, kev ua tau zoo, kev sim, thiab lwm yam ntawm cov yeeb nkab sib txuas kom zoo thiab kev nyab xeeb ntawm cov yeeb nkab txuas. Yog li ntawd, thaum xaiv cov yeeb nkab fittings, cov neeg siv yuav tsum tau them sai sai rau seb lawv puas ua raws li cov qauv tsim nyog thiab seb lawv puas tau dhau los ntawm cov ntawv pov thawj thiab kev sim.
Tsis tas li ntawd, muaj qee qhov teeb meem yuav tsum paub txog thaum siv cov couplings. Piv txwv li, ua ntej kev teeb tsa, qhov loj ntawm cov kav dej thiab cov pob qij txha yuav tsum tau kuaj xyuas kom ntseeg tau tias cov kev sib txuas yog huv thiab qhuav; Thaum lub sij hawm lub installation txheej txheem, ua raws li cov lus qhia los yog cov txheej txheem kev khiav hauj lwm kom tsis txhob nruj heev los yog puas tsuaj rau lub sealing Cheebtsam; Thaum siv, kev sib khi thiab kev ruaj ntseg ntawm kev sib koom tes yuav tsum tau kuaj xyuas kom sai sai thiab daws cov teeb meem tshwm sim.
