ʻO ka pā pahu wai aluminahiki ke hoʻohana ʻia i ka mana uila, ka ʻaila, kemika, ke gula, ka mining, ka pipeline hoʻomaʻemaʻe wai a me nā ʻoihana ʻē aʻe o ka pipeline ball valve.Pīla kīwila waie like me ka ʻoki ʻia a hoʻokomo ʻia i loko o ka pipeline medium, hiki ke kūpono no ka nominal pressure PN1.6 ~ 10.0Mpa, ka mahana hana -29 ~ 540 ℃ petroleum, chemical, mining, metallurgy, power industry a me nā kūlana hana ʻē aʻe o ka pipeline ball valve .ʻOi aku no ka hoʻokuʻu ʻana o ka lehu, ka ʻōnaehana hoʻokuʻu slag, ka hoʻokuʻu ʻana, ka ʻōnaehana sege, kona ola lawelawe ma mua o ka pā wai valve maʻamau i hoʻonui ʻia ma mua o 10 mau manawa, hiki ke hoʻokō i ka hoʻohana ʻana i ka lole kiʻekiʻe, ke ʻano corrosion ikaika.ʻO nā kiko'ī penei:
1. ʻO nā ʻāpana a pau e pili ana me ka mea waena, he mau mea hana seramika, nona ka paʻa a me ka paʻakikī kemika (Rockwell hardness HRC90), a ʻo ka paʻakikī ka lua o ke daimana.No laila, ʻo kapā kīwī waii hana ʻia me nā mea seramika he kiʻekiʻe loa ka pale ʻana i ka lole, ka pale ʻana i ka corrosion, ke kū ʻana o ka erosion, ka hoʻohaʻahaʻa wela maikaʻi a me ka hoʻonui ʻana i ka wela liʻiliʻi.
2. Hana ʻia me ka alumina ceramic microporous pūʻulu ma ka ʻili o kakiwi waiHe maikaʻi ka maʻalahi a me ka lubrication pono'ī, hoʻololi i nā mea kahiko i hanaʻia me nā papa valve wai'ē aʻe a me keʻano o ka friction a me ka lubrication o ka medium transmission, hiki ke hoʻokō i ka sila maikaʻi, hoʻololi loa i ka hoʻohanaʻana i ka valve wai maʻamau e maʻalahi ka leak, sealing surface nā pōʻino ʻino.
3. Ceramic maikaʻi ʻaʻahu kūʻē, no laila kapā kīpē seramikapaʻa, hilinaʻi kiʻekiʻe.ʻO ke ola lawelawe lōʻihi, ʻo ia ka titanium alloy valve sheet a me nā mea kahiko i hana ʻia i ka pepa valve 2-4 mau manawa.
4 I loko o ka pipeline ka lawe ʻana i ka ʻeleʻele granular paʻakikī kiʻekiʻe.pā kīpē seramikaloaʻa i ka pono kūʻokoʻa like ʻole.
