ʻOkoʻa ma waena o ka Ball Valve a me ka Butterfly Valve
ʻO ka ʻokoʻa nui ma waena o nā kiwikā pepeke a me nā kiwikā pōpō, ʻo ia ka wehe piha ʻana a pani ʻia paha o ka kiwikā pepeke ma ka hoʻohana ʻana i kahi diski ʻoiai ʻo ka kiwikā pōpō e hoʻohana ana i kahi pōpō hakahaka, puka a pivoting e hana i kēlā. ʻO ka diski o ka kiwikā pepeke a me ke kumu kiwikā o ka kiwikā pōpō e hoʻohuli a puni ko lākou axis ponoʻī. Hiki i ka kiwikā pepeke ke hoʻoponopono i ke kahe ma o kona kekelē hāmama ʻoiai ʻaʻole kūpono ka kiwikā pōpō e hana i kēia.
ʻO ke ʻano o ka valve butterfly he wehe wikiwiki a pani ʻia, maʻalahi ke ʻano a me ke kumukūʻai haʻahaʻa, akā ʻaʻole maikaʻi kona paʻa a me ka hiki ke hāpai. Ua like nā hiʻohiʻona o nā valves pōpō me nā valves puka, akā ma muli o ka palena o ka nui a me ke kū'ē ʻana i ka wehe a me ka pani ʻana, he paʻakikī no ka valve pōpō ke lilo i valve nui ke anawaena.
ʻO ke kumumanaʻo o ke ʻano o nā kiwikā pepeke e kūpono loa ai lākou e hana ʻia i mau kiwikā nui. Hoʻokomo ʻia ka diski o ka kiwikā pepeke ma ke kuhikuhi anawaena o ka pipeline. Ma ke ala cylindrical o ke kino kiwikā pepeke, hoʻohuli ka diski a puni ke axis. Ke hoʻohuli ʻia i ka hapaha huli, ua wehe piha ʻia ka kiwikā. He ʻano maʻalahi ka kiwikā pepeke, haʻahaʻa ke kumukūʻai a ākea ka laulā hiki ke hoʻololi ʻia. Hoʻohana pinepine ʻia nā kiwikā pōpō no nā wai a me nā kinoea me ka ʻole o nā ʻāpana a me nā haumia. He liʻiliʻi ka pohō kaomi wai o kēia mau kiwikā, hana sila maikaʻi a kiʻekiʻe ke kumukūʻai.
I ka hoʻohālikelike ʻana, ʻoi aku ka maikaʻi o ke sila ʻana o ka valve pōpō ma mua o ka valve butterfly. Hilinaʻi ka sila valve pōpō i ke kaomi ʻana ma ka ʻili poepoe e ka noho valve no ka manawa lōʻihi, kahi e ʻoi aku ka wikiwiki o ka ʻaʻahu ma mua o ka valve semi-ball. Hana pinepine ʻia ka valve pōpō me ka mea sila palupalu, a he paʻakikī ke hoʻohana ʻana i nā pipeline wela kiʻekiʻe a me ke kaomi kiʻekiʻe. Loaʻa i ka valve butterfly kahi noho laholio, kahi mamao loa mai ka hana sila paʻakikī metala o nā valves semi-ball, nā valves pōpō a me nā valves puka. Ma hope o ka hoʻohana lōʻihi ʻana o ka valve semi-ball, e ʻaʻahu iki ʻia ka noho valve, a hiki ke hoʻohana mau ʻia ma o ka hoʻoponopono ʻana. Ke wehe ʻia a pani ʻia ke kumu a me ka hoʻopaʻa ʻana, pono wale ke kumu e hoʻohuli i ka hapaha. Ke loaʻa kekahi hōʻailona o ka leakage, e kaomi i ka bolt o ka gland packing e ʻike ʻaʻohe leakage. Eia nō naʻe, ʻaʻole i hoʻohana nui ʻia nā valves ʻē aʻe me ka leakage liʻiliʻi, a ua pani ʻia nā valves me ka leakage nui.
I ke kaʻina hana o ka wehe ʻana a me ka pani ʻana, hana ka valve pōpō ma lalo o ka ikaika paʻa o nā noho valve ma nā wēlau ʻelua. Ke hoʻohālikelike ʻia me ka valve semi-ball, ʻoi aku ka nui o ka torque wehe a me ka pani ʻana o ka valve pōpō. A ʻo ka nui o ke anawaena nominal, ʻoi aku ka maopopo o ka ʻokoʻa o ka torque wehe a me ka pani ʻana. Hoʻomaopopo ʻia ka wehe ʻana a me ka pani ʻana o ka valve butterfly ma ka lanakila ʻana i ka deformation o ka rubber. Eia nō naʻe, lōʻihi ka manawa e hana ai i nā valves puka a me nā valves globe a he hana paʻakikī hoʻi ka hana ʻana i kēlā.
ʻO ke kiwikā pōpō a me ke kiwikā plug he ʻano like. ʻo ke kiwikā pōpō wale nō ka pōpō hakahaka e kāohi i ke kahe ʻana ma o ia mea. Hoʻohana nui ʻia nā kiwikā pōpō e ʻoki, hoʻolaha a hoʻololi i ke kuhikuhi kahe o ka medium i loko o nā pipelines.
