Kub kub valve hais txog lub valve uas ua haujlwm nyob rau hauv qhov kub thiab txias, uas feem ntau yog siv hauv roj av, tshuaj lom neeg kev lag luam, metallurgy thiab lwm yam lag luam. Vim muaj ntau yam kev sib tw hauv kev hloov pauv ntawm cov khoom siv, kev ruaj ntseg ntawm cov qauv thiab kev sib khi hauv qhov kub thiab txias, kev tsim cov khoom siv kub kub yog qhov nyuaj. Kab lus no yuav yog los ntawm kev kub siab valve tsim teeb meem thiab kev xav tau ntawm ob yam ntawm kev tsom xam.
Ua ntej, kev tsim khoom nyuaj
1. Kev xaiv cov khoom siv: Nyob rau hauv ib puag ncig kub, kev ua haujlwm ntawm cov khoom siv tau yooj yim hloov, xws li oxidation tsis kam, hnav tsis kam, lub zog thiab lwm yam. Yog li ntawd, nyob rau hauv kev tsim cov kub kub li qub, nws yog ib qhov tsim nyog los xaiv cov ntaub ntawv uas zoo heev kub kev ua tau zoo, xws li superalloys, ceramics, composite cov ntaub ntawv, thiab lwm yam.
2. Cov qauv tsim: Lub siab kub valve ua haujlwm nyob rau hauv qhov chaw kub kub, thiab nws cov qauv tsim yuav tsum tau coj mus rau hauv tus account lub thermal expansion, thermal deformation thiab thermal stress thiab lwm yam ntawm cov khoom los xyuas kom meej tias lub valve muaj kev ruaj ntseg zoo. thiab sealing nyob rau hauv qhov kub thiab txias.
3. Sealing tshuab: nyob rau hauv ib puag ncig kub, kev ua haujlwm ntawm cov ntaub ntawv sealing tau yooj yim cuam tshuam, xws li oxidation, hnav thiab lwm yam. Yog li ntawd, thaum tsim lub siab kub li qub, nws yog ib qho tsim nyog yuav tsum tau siv cov khoom sib khi nrog kev ua haujlwm siab kub sealing zoo thiab txais yuav cov qauv sealing tsim nyog.
4. Cov txheej txheem tsim khoom: Cov txheej txheem ntawm kev tsim cov txheej txheem kub siab, xws li vuam, machining, sib dhos thiab lwm yam txheej txheem yuav tsum tau tswj nruj me ntsis kom ntseeg tau tias qhov zoo thiab kev ua haujlwm ntawm lub valve.
2. Kev xav tau
1. Lub zog kub kub: qhov kub thiab txias li qub yuav tsum muaj lub zog kub txaus kom ntseeg tau tias yuav tsis muaj deformation lossis kev puas tsuaj nyob rau hauv qhov kub thiab txias.
2. Oxidation tsis kam: cov khoom siv kub ntawm lub valve yuav tsum muaj oxidation zoo los tiv thaiv oxidative corrosion nyob rau hauv qhov kub thiab txias.
3. Hnav tsis kam: Kub kub li qub yuav tsum muaj kev hnav txaus kom ntseeg tau tias lawv yuav tsis poob vim hnav nyob rau hauv qhov kub thiab txias.
4. Tightness: siab kub li qub yuav tsum muaj zoo nruj kom ntseeg tau tias yuav tsis muaj to nyob rau hauv qhov kub thiab txias ib puag ncig.
5. Stability: siab kub li qub yuav tsum muaj kev ruaj ntseg zoo los xyuas kom meej tias lawv tuaj yeem ua haujlwm ib txwm nyob rau hauv qhov kub thiab txias.
Kev kub siab valve tsim muaj qee qhov teeb meem, yuav tsum tau kov yeej cov khoom xaiv, kev tsim qauv, sealing tshuab, kev tsim khoom thiab lwm yam teeb meem. Nyob rau tib lub sijhawm, lub siab kub valve yuav tsum tau ua kom tau raws li cov kev xav tau ntawm kev kub siab lub zog, oxidation tsis kam, hnav tsis kam, sealing, ruaj khov thiab lwm yam hauv cov txheej txheem tsim khoom kom ntseeg tau tias qhov zoo thiab kev ua haujlwm ntawm lub valve.
