Basic Introduction
Hardfaced valve balls yog tsim los ntawm kev siv siab -kev ua tau zoo cemented carbide txheej (xws li Stellite, tungsten carbide, chromium carbide, thiab lwm yam) mus rau lub sealing nto ntawm lub kheej kheej substrate los ntawm cov txheej txheem saum npoo ntxiv dag zog, tsim cov qauv sib xyaw nrog metallurgical bonding los yog high-strength.{2} Cov qauv tsim tshwj xeeb no khaws cov tawv tawv zoo heev thiab cuam tshuam tsis zoo ntawm cov khoom siv hauv paus thaum muab cov tawv tawv hnyav, hnav tsis kam, tiv taus yaig, siab -kub tsis kam, thiab corrosion kuj rau saum npoo. Nws tiv taus ntev - lub sij hawm sib xyaw tawm tsam los ntawm cov xov xwm uas muaj cov khoom muaj zog, siab - cov kua dej nrawm, thiab cov tshuaj corrosive heev. Cov txheej tawv tawv tuaj yeem ncav cuag millimeter-theem thickness nrog adhesion muaj zog, tiv taus tev thiab tawg. Muaj ntau yam khoom siv carbide kom haum rau cov kev pabcuam tshwj xeeb. Cov khoom lag luam yog qhov tshwj xeeb tshaj yog rau cov ntawv thov hnyav hauv cov tshuaj coal, slurry thauj, tsim hluav taws xob, thiab roj av refining industries qhov twg muaj kev puas tsuaj, khaus erosion, kub siab, thiab siab siab ntau, ua rau nws yog ib qho tseem ceeb tivthaiv rau ncua kev pab cuam valve lub neej thiab ua hauj lwm kev cia siab rau.

FAQ
Dab tsi yog qhov tseem ceeb ntawm hardfaced valve pob?
Hardfaced valve npas tsim cov cemented carbide reinforced txheej rau ntawm qhov chaw sib khi los ntawm kev sib tshooj vuam lossis thermal txau, xa cov khoom hnyav, yaig, kub kub, thiab corrosion kuj thaum lub substrate tawv absorbs cuam tshuam loads. Cov qauv sib xyaw ua tau zoo tshaj plaws nyob rau hauv cov xwm txheej hnyav uas muaj kev puas tsuaj thiab kev cuam tshuam, cuam tshuam rau lub neej kev pab cuam valve thiab kev ntseeg siab.
Dab tsi yog cov khoom siv tawv tawv thiab xaiv lawv li cas?
Cov ntaub ntawv muaj xws li Stellite (cobalt-based), tungsten carbide (WC), chromium carbide (Cr₃C₂), thiab nickel-based carbides. Stellite muaj qhov sib npaug ntawm qhov kub thiab txias, corrosion, thiab cuam tshuam tsis kam; WC muab qhov siab tshaj plaws hardness rau abrasive hnav; CrC ua tau zoo nyob rau hauv high-sulfur, oxidizing ib puag ncig ntawm qhov kub thiab txias. Kev xaiv nyob ntawm seb muaj pes tsawg leeg, qhov kub thiab txias, qhov loj me, thiab qhov cuam tshuam loj. Peb pab neeg tuaj yeem pab nrog cov lus pom zoo.
Dab tsi yog qhov txawv ntawm hardfaced valve pob thiab khoom tungsten carbide (TCC) valve pob?
Cov khoom tungsten carbide yog homogeneously nyuaj tab sis nkig, nrog kev cuam tshuam tsis zoo - lawv nquag tawg hauv qhov poob siab loj. Hardfaced npas, nyob rau hauv sib piv, feature ib tug tawv steel substrate nrog ib tug nyuaj nto txheej, combining siab deg hardness nrog zoo heev tej yam toughness. Ntxiv mus, txheej tawv tawv tuaj yeem kho tau los ntawm kev rov ua dua thaum hnav, txo cov nqi hloov. Yog li, cov khoom siv tawv tawv zoo dua rau cov xwm txheej uas muaj kev cuam tshuam thiab puas, thaum TCC cov khoom zoo dua rau kev puas tsuaj tsis muaj kev cuam tshuam loj.
Puas yuav cov txheej tawv tawv tawv los yog tawg thaum ua haujlwm?
Nrog rau kev xaiv cov khoom tsim nyog thiab kev tswj cov txheej txheem paub tab, cov txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej hlau los yog cov khoom siv muaj zog sib cuam tshuam nrog cov substrate, ua tiav los ntawm cov txheej txheem hloov pauv thiab kev ntsuas kev ntxhov siab, ua rau muaj kev cuam tshuam zoo heev. Raws li kev ua haujlwm ib txwm muaj, txheej yuav tsis tev lossis tawg thiab tuaj yeem muab kev pabcuam ruaj khov mus ntev. Rau kev hloov pauv huab cua lossis kev caij tsheb kauj vab thermal, peb muab cov txheej txheem kho kom haum rau kev txhim kho kom ruaj khov.
