Cov yam ntxwv ntawm cov khoom
1. Tag nrho cov khoom nyob rau hauv kev sib cuag nrog nruab nrab yog structural ceramics, uas muaj tshuaj stability thiab hardness (Rockwell hardness HRC90), thib ob tsuas yog pob zeb diamond. Yog li ntawd, lub valve muaj siab hnav tsis kam, corrosion kuj, yaig kuj, thiab zoo thermal rwb thaiv tsev, me me thermal expansion.
2. Lub kheej kheej yog tsim los ntawm kev sib tsoo cov cuab yeej siv siab heev thiab siv tshuab. Lub kheej kheej muaj siab roundness raug thiab zoo nto zoo. Tom qab sib tsoo nrog lub rooj zaum valve, Zr02 ceramics tuaj yeem ua tiav kev sib khi zoo los ntawm nws tus kheej lubrication.
3. Nws hloov tag nrho cov tsis xws luag ntawm hlau nyuaj sealing pob valve, xws li yooj yim to, siab torque thiab corrosion kuj ntawm sealing nto.
4. Kev hnav zoo ntawm ceramics ua rau lub valve ruaj khov thiab txhim khu kev qha. Nws lub neej kev pab cuam ntev, 2-4 zaug ntev li ntawm titanium alloy valve thiab Monel valve. Lub valve no muaj qhov sib piv tsis zoo rau qhov siab hardness granular media lossis mos granular tab sis corrosive media. Nws tseem yog tib lub valve tsim nyog rau hom kev tshaj tawm tam sim no.
