ʻOkoʻa ma waena o Ball Valve a Butterfly Valve

ʻOkoʻa ma waena o Ball Valve a Butterfly Valve

ʻO ka ʻokoʻa nui ma waena o nā kiwi lele a me nā kiwi pōpō, ʻo ia ka wehe piha ʻana a pani ʻia paha o ka valve butterfly ma o ka hoʻohana ʻana i kahi diski ʻoiai ke hoʻohana nei ka valve pōleʻa i ka pōlele ʻāwīwī a pivoting e hana i kēlā.ʻO ka disc o ka valve butterfly a me ka valve core o ka valve poepoe e hoʻohuli a puni ko lākou axis.Hiki i ka valve butterfly ke hoʻoponopono i ke kahe ʻana ma kona degere hāmama ʻoiai ʻaʻole maʻalahi ka valve pōlele e hana i kēia.

Hōʻike ʻia ka valve Butterfly e ka wehe wikiwiki ʻana a me ka pani ʻana, ke ʻano maʻalahi a me ke kumu kūʻai haʻahaʻa, akā ʻaʻole maikaʻi kona paʻa a me ka hiki ʻana.ʻO nā hiʻohiʻona o nā kiwi pōleʻa e like me nā kiwi o ka ʻīpuka, akā ma muli o ka palena o ka leo a me ka wehe ʻana a me ka pani ʻana i ke kūpaʻa, paʻakikī ke ʻano o ke anawaena nui.

ʻO ke kumu o ka hoʻolālā ʻana o nā valve butterfly he mea kūpono ia e hana ʻia i loko o nā anawaena nui.Hoʻokomo ʻia ka disc o ka valve butterfly ma ke anawaena o ka pipeline.Ma ka ʻaoʻao cylindrical o ke kino valve butterfly, kaʻapuni ka disc a puni ke axis.Ke hoʻohuli ʻia i ka hapahā huli, ua hāmama loa ka pahu.He ʻano maʻalahi ko ka valve butterfly, ke kumu kūʻai haʻahaʻa a me ka laulā hiki ke hoʻololi.Hoʻohana mau ʻia nā kiwi pōkā no nā wai a me nā kinoea me ka ʻole o nā ʻāpana a me nā haumia.ʻO kēia mau valve me ka liʻiliʻi liʻiliʻi o ke kaomi wai, ka hana hoʻopaʻa sila maikaʻi a me ke kumukūʻai kiʻekiʻe.

I ka hoʻohālikelike ʻana, ʻoi aku ka maikaʻi o ka hoʻopaʻa ʻana i ka valve ball ma mua o ka valve butterfly.Ke hilinaʻi nei ka seal valve ball i ka paʻi ʻana ma ka ʻili spherical e ka noho valve no ka manawa lōʻihi, ʻo ia ka mea e ʻoi aku ka wikiwiki ma mua o ka valve semi-ball.Hoʻohana pinepine ʻia ka pahu pōpō me nā mea hoʻopaʻa hoʻopaʻa maʻalahi, a paʻakikī ke hoʻohana ʻia i nā pipeline kiʻekiʻe a me ke kiʻekiʻe.He noho wili ko ka pahu lele, kahi mamao loa mai ka hana hoʻopaʻa metala paʻakikī o nā kiwipa semi-pope, nā kiwi pōpō a me nā kiwi puka.Ma hope o ka lōʻihi o ka hoʻohana ʻana i ka valve semi-ball, e hoʻopau 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 paʻi ʻana, pono e hoʻohuli ke kumu i hoʻokahi hapaha huli.Ke loaʻa kekahi hōʻailona o ka leakage, e kaomi i ka bolt o ka ʻeke packing e ʻike ʻaʻole leakage.Eia nō naʻe, ʻaʻole hoʻohana ʻia nā kiwi ʻē aʻe me ka liʻiliʻi liʻiliʻi, a ua hoʻololi ʻia nā kiwi me ka leakage nui.

I ke kaʻina hana o ka wehe ʻana a me ka pani ʻana, e hana ana ka pahu pōpō ma lalo o ka ikaika paʻa o nā noho valve ma nā ʻaoʻao ʻelua.Ke hoʻohālikelike ʻia me ka valve semi-ball, ʻoi aku ka nui o ka puka ʻana a me ka pani pani ʻana o ka pā.A ʻoi aku ka nui o ke anawaena nominal, ʻoi aku ka maopopo o ka ʻokoʻa o ka wehe ʻana 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 ʻīpuka puka a me nā kīwaha honua a paʻakikī hoʻi e hana i kēlā.

ʻO ke ʻano like ke ʻano o ka pahu kinipōpō a me ka pā kī.ʻO ka pāpū kinipoe wale nō ka pōleʻa puka e hoʻomalu i ke kahe ʻana ma loko.Hoʻohana nui ʻia nā kiwi pōleʻa e ʻoki, puʻunaue a hoʻololi i ke ala kahe o ka waena i nā pipelines.
