Cov saum npoo ntim yog qhov tseem ceeb tshaj plaws ua haujlwm ntawm lubib lub dab tsi uas qhib thiab kaw, qhov zoo tshaj plaws ntawm kev sib khi ncaj qha cuam tshuam rau lub neej pabcuam ntawm lub valve, thiab cov khoom ntawm cov chaw sib khi yog qhov tseem ceeb ntawm kev sib khi saum npoo. Yog li, cov hauv qab no yuav tsum txiav txim siab thaum xaiv cov khoom lag luam nto:
① corrosion resistant.
Nyob rau hauv qhov kev txiav txim ntawm nruab nrab, kev sib khi saum npoo yog rhuav tshem. Yog hais tias cov nplaim doged, kev sib khi ua tau zoo tsis tuaj yeem lav. Yog li, cov khoom sealing nto yuav tsum yog corrosion resistant. Cov corrosion tsis kam ntawm cov ntaub ntawv tsuas yog nyob ntawm lawv cov peev xwm thiab tshuaj lom neeg ruaj khov.
② Tshawb nrhiav.
"Kos" yog hais txog kev puas tsuaj los ntawm kev sib deev thaum lub sijhawm txheeb ze txav ntawm kev sib khi saum npoo. Qhov no zoo ntawm kev puas tsuaj no yuav tsis muaj kev puas tsuaj rau kev sib tsoo saum npoo. Yog li, cov khoom sealing nto yuav tsum muaj qhov zoo tsis kam, tshwj xeeb yog rooj vag valve. Cov khawb paus tiv thaiv cov khoom siv feem ntau txiav txim siab los ntawm cov khoom sab hauv cov ntaub ntawv.
③ yaig kuj.
"Yaig" yog cov txheej txheem uas kev sib khi saum npoo muaj kev puas tsuaj thaum lub nruab nrab ntws los ntawm kev sib khi saum npoo ntawm kev kub ceev. Qhov kev puas tsuaj no yog qhov pom tseeb ntau dua nyob rau hauv lub valotle valve thiab valve valve siv nyob rau hauv qhov kub thiab kub siab rau kev sib tw ua tau zoo. Yog li ntawd, yaig kuj tseem yog ib qho ntawm cov cai tseem ceeb ntawm cov khoom sib khi.
Yuav tsum muaj ib co degree ntawm hardness, thiab lub hardness yuav txo qis nyob rau hauv qhov kev ua haujlwm kub.
⑤ Cov kab nthuav dav ntawm kev sib khi ntawm cov npoo thiab cov khoom siv lub cev yuav tsum zoo sib xws, uas yog qhov tseem ceeb rau cov qauv ntawm inlaidSealing nplhaib, yog li kom tsis txhob muaj kev ntxhov siab ntxiv thiab xoob qis hauv qhov kub.
⑥ Thaum siv qhov kub thiab txias, nws yuav tsum muaj oxidation txaus tiv taus, thermal rog tsis kam thiab thermal voj voog.
Nyob rau hauv qhov teeb meem tam sim no, nws yog qhov nyuaj heev kom pom cov sorting cov ntaub ntawv nto uas ua tiav cov cai saum toj no. Peb tsuas yog tsom rau kev ua raws li cov kev xav tau ntawm qee yam raws li kev sib txawv hom valve thiab kev siv. Piv txwv li, lub pob valve nyob rau hauv nruab nrab ceev yuav tsum them nyiaj tshwj xeeb rau cov kev xav tau ntawm kev yaig tsis zoo ntawm kev sib khi saum npoo; Thaum nruab nrab muaj cov khoom siv impurities, cov khoom sib khi ua cov khoom siv saum toj uas muaj kev tawv ntau dua.
