He aha ka Valve kila kila

A kiwikā kila kilahe kiwikā i hana ʻia me ke kila kila. Hiki ke hoʻohana ʻia e kāohi i ke kahe ʻana o nā ʻano wai like ʻole, me ka ea, ka wai, ka mahu, nā ʻano mea ʻino like ʻole, ka slurry, ka ʻaila, nā metala wai, a me nā mea radioactive.

1. ʻIke Kumu a me nā ʻAno Nui o nā Valves Kila Kila

Ka Wehewehena a me nā ʻAno Koʻikoʻi:

A kiwikā kila kilahe kiwikā nona nā ʻāpana nui, e like me ke kino kiwikā a me ka uhi kiwikā, i hana ʻia me ke kila kila.

He ʻano kiwikā ia ʻaʻole e maʻalahi i ka popo, kūpale i ka pala, a he kūpaʻa maikaʻi i ke kaomi.

Hiki i ka pae kaomi hana o nā kiwikā kila kila ke loaʻa mai ke kaomi haʻahaʻa loa o 0.0013MPa a i ke kaomi kiʻekiʻe loa o 1000MPa, a hiki i ka pae mahana kūpono ke loaʻa mai ka mahana haʻahaʻa loa o -269 ℃ a i ka mahana kiʻekiʻe o 1430 ℃. Hiki iā ia ke hoʻomalu i nā ʻano wai like ʻole, me ka wai, ka mahu, ka ʻaila, ke kinoea, ka slurry, nā ʻano mea ʻino like ʻole, nā metala wai, a me nā wai radioactive.

• Ke Kū'ē Mahana Kiʻekiʻe: He kiʻekiʻe ke kiko heheʻe o ke kila kila a hiki ke kū i ka hoʻohana ʻana i nā wahi wela kiʻekiʻe.
