Lub sealing nto yog qhov tseem ceeb tshaj plaws ua hauj lwm nto ntawm lubvalve, qhov zoo ntawm sealing nto ncaj qha cuam tshuam rau lub neej kev pab cuam ntawm lub valve, thiab cov khoom ntawm lub sealing nto yog ib qho tseem ceeb los xyuas kom meej qhov zoo ntawm sealing nto. Yog li ntawd, cov hauv qab no yuav tsum tau txiav txim siab thaum xaiv valve sealing nto cov ntaub ntawv:
① Corrosion resistant.
Nyob rau hauv qhov kev txiav txim ntawm nruab nrab, lub sealing nto yog puas. Yog tias qhov chaw puas lawm, qhov kev sib khi tsis tuaj yeem lav tau. Yog li ntawd, lub sealing nto cov khoom yuav tsum yog corrosion resistant. Lub corrosion kuj ntawm cov ntaub ntawv mas nyob ntawm lawv cov khoom thiab tshuaj stability.
② Scratch resistant.
"Scratch" yog hais txog kev puas tsuaj los ntawm kev sib txhuam thaum lub sij hawm tus txheeb ze txav ntawm sealing nto. Hom kev puas tsuaj no yuav ua rau muaj kev puas tsuaj rau lub sealing nto. Yog li ntawd, cov khoom siv sealing nto yuav tsum muaj kev khawb zoo, tshwj xeeb tshaj yog lub rooj vag valve. Kev khawb tsis kam ntawm cov ntaub ntawv feem ntau txiav txim siab los ntawm cov khoom sab hauv ntawm cov ntaub ntawv.
③ Erosion kuj.
"Erosion" yog cov txheej txheem uas lub sealing nto raug puas tsuaj thaum nruab nrab ntws los ntawm lub sealing nto ntawm kev kub ceev. Qhov kev puas tsuaj no yog pom tseeb dua nyob rau hauv lub throttle valve thiab kev nyab xeeb valve siv nyob rau hauv qhov kub thiab txias siab chav nruab nrab, uas muaj kev cuam tshuam zoo rau kev sealing kev ua tau zoo. Yog li ntawd, erosion kuj tseem yog ib qho tseem ceeb ntawm cov khoom siv sealing nto.
④ Yuav tsum muaj qee qhov hardness, thiab qhov hardness yuav txo qis heev raws li qhov ntsuas kub ua haujlwm.
⑤ Cov kab nthuav dav coefficient ntawm sealing nto thiab cov khoom siv lub cev yuav tsum zoo sib xws, uas yog qhov tseem ceeb tshaj rau cov qauv ntawm inlaid.sealing nplhaib, kom tsis txhob muaj kev ntxhov siab ntxiv thiab looseness nyob rau hauv qhov kub thiab txias.
⑥ Thaum siv qhov kub thiab txias, nws yuav tsum muaj kev tiv thaiv oxidation txaus, thermal qaug zog thiab thermal voj voog.
Nyob rau hauv cov xwm txheej tam sim no, nws yog qhov nyuaj heev los nrhiav cov ntaub ntawv sealing uas ua tau raws li cov kev xav tau saum toj no. Peb tsuas tuaj yeem tsom mus ua kom tau raws li qhov yuav tsum tau ua ntawm qee yam raws li ntau hom valve thiab kev siv. Piv txwv li, lub valve siv nyob rau hauv high-ceev nruab nrab yuav tsum tau them tshwj xeeb mloog mus rau qhov yuav tsum tau ntawm yaig tsis kam ntawm sealing nto; Thaum qhov nruab nrab muaj cov khoom impurities, cov khoom siv sealing nto nrog hardness siab dua yuav tsum raug xaiv.
