Alumina dej valve phaj

Alumina dej valve phajtuaj yeem siv rau hauv hluav taws xob, roj av, tshuaj, kub, mining, dej phwj kho kav dej thiab lwm yam kev lag luam ntawm cov raj xa dej.Dej valve ceramic phajRaws li kev txiav tawm lossis muab tso rau hauv cov kav dej nruab nrab, tuaj yeem tsim nyog rau lub siab nominal PN1.6 ~ 10.0Mpa, ua haujlwm kub -29 ~ 540 ℃ roj av, tshuaj lom neeg, mining, metallurgy, fais fab kev lag luam thiab lwm yam kev ua haujlwm ntawm lub raj xa dej. .Tshwj xeeb tshaj yog rau cov hmoov tshauv tawm, slag paug system, tso tawm, dej phwj system, nws cov kev pab cuam lub neej tshaj li zoo tib yam alloy dej valve phaj nce ntau tshaj 10 lub sij hawm, muaj peev xwm ua tau raws li kev siv siab hnav, muaj zog corrosion ib puag ncig.Cov ntsiab lus yog raws li nram no:

1. Tag nrho cov khoom nyob rau hauv kev sib cuag nrog nruab nrab yog cov khoom siv ceramic, uas nws cov tshuaj stability thiab hardness siab heev (Rockwell hardness HRC90), thiab hardness yog thib ob tsuas yog pob zeb diamond.Yog li ntawd, lubdej valve phajua los ntawm cov ntaub ntawv ceramic muaj qhov hnav tsis kam, corrosion kuj, yaig tsis kam, rwb thaiv tsev zoo thiab thermal expansion me me.

2. Ua los ntawm alumina ceramic microporous pawg rau ntawm qhov chawdej valveNws muaj qhov smoothness zoo thiab nws tus kheej lubrication, hloov cov khoom siv ib txwm ua los ntawm lwm cov dej valve daim hlau thiab cov txheej txheem ntawm kev sib txhuam thiab lubrication ntawm kev sib kis nruab nrab, tuaj yeem ua tiav zoo sealing, hloov tag nrho cov kev siv cov tsoos dej valve yog ib qho yooj yim los mus, sealing nto. corrosion tsis xws luag.

3. Ceramic zoo hnav tsis kam, kom lubceramic valve phajruaj, siab ntseeg.Lub neej ua haujlwm ntev, yog titanium alloy valve daim ntawv thiab lwm yam khoom siv ua los ntawm cov ntawv valve 2-4 zaug.

4 Nyob rau hauv kev thauj mus los ntawm lub raj xa dej ntawm lub siab hardness granular nruab nrab, hmoov nruab nrab los yog mos hais tab sis corrosive nruab nrab,ceramic valve phajmuaj incomparable kiag li kom zoo dua.
