Nā hiʻohiʻona huahana
1. ʻO nā ʻāpana a pau e pili ana me ka mea waena, he mau seramics kūkulu ʻia, nona ke kūpaʻa kemika kiʻekiʻe a me ka paʻakikī (Rockwell hardness HRC90), ʻelua wale nō i ke daimana. No laila, he kiʻekiʻe loa ka pale ʻana o ka valve, ka pale ʻana i ka corrosion, ka pale ʻana i ka erosion, a me ka insulation thermal maikaʻi, ka hoʻonui ʻana i ka wela liʻiliʻi.
2. Hana 'ia ka poepoe e na lako wili a me ka 'enehana. He kiʻekiʻe ka pōʻaiapuni pololei a me ka maikaʻi o ka ʻili. Ma hope o ka wili ʻana me ka noho valve, hiki i ka Zr02 ceramics ke hoʻokō maikaʻi i ka hana sila ʻana ma o ka lubrication ponoʻī.
3. Ua hoʻololi loa ia i nā hemahema o ka metala paʻakikī sealing ball valve, e like me ka maʻalahi leakage, kiʻekiʻe torque a me ka corrosion kū'ē o ka sila ili.
4. ʻO ke kūpaʻa maikaʻi ʻana o nā seramika e paʻa a paʻa i ka valve. He lōʻihi kona ola lawelawe, 2-4 mau manawa e like me ka lōʻihi o ka valve titanium alloy a me ka valve Monel. Loaʻa i kēia valve nā pono kūpono ʻole no ka media granular paʻakikī kiʻekiʻe a i ʻole media granular palupalu akā corrosive. ʻO ia wale nō ka valve kūpono no kēia ʻano media i kēia manawa.
