He ʻelua ʻaoʻao anei nā kiwi lele?

ʻO ka Butterfly Valve kahi ʻano o ka mana kahe me ka hāhā-turn rotational motion, Hoʻohana ʻia ia i nā pipelines e hoʻoponopono a hoʻokaʻawale paha i ke kahe o nā wai (wai a i ʻole nā kinoea), Eia nō naʻe, ʻo ka valve butterfly maikaʻi maikaʻi e hoʻolako i kahi sila maikaʻi. He ʻelua ʻaoʻao anei nā ʻūhā lele? ʻO ka maʻamau, hoʻokaʻawale mākou i ka valve butterfly i nā valve butterfly Concentric a me ka valve butterfly eccentric.
E kūkākūkā mākou e pili ana i ka concentric butterfly valve bidirectional e like me lalo:

He aha ia Concentric butterfly valve?

ʻIke ʻia ʻo Concentric butterfly valve e like me ka resilient seated a i ʻole zero-offset butterfly valves, ʻo kā lākou mau ʻāpana: kino Valve, disc, noho, kumu a sila. ʻO kēia ke ʻano o ka disc i loko o kahi noho palupalu, Hiki i ka mea noho ke komo i ka EPDM, NBR Viton Silicon Teflon Hypalon a i ʻole elastomer.

Pehea e hana ai i ka valve concentric butterfly?

He mea maʻalahi ke kūkulu ʻana i ka valve butterfly, aia ʻekolu mau ʻano o ka mea hoʻokele no ka hana ʻana: Lever Handle no ka liʻiliʻi liʻiliʻi, Worm Gear box no nā valves nui e maʻalahi ai ka hoʻokele a me ka hana Automated (e komo pū me Electric and Pneumatic Actuators)
Hoʻohana ʻia ka valve butterfly ma ka hoʻohuli ʻana i kahi disk (a i ʻole vane) i loko o ka paipu e hoʻomalu i ke kahe o ka wai. Hoʻokomo ʻia ka diski ma luna o kahi kumu e hele ai i loko o ke kino valve, a hoʻohuli i ke kumu e hoʻololi i ka disk e wehe a pani paha i ka pahu, E like me ka holo ʻana o ka pahu, huli ka diski i ka wehe a i ʻole ka wehe ʻana i kahi kūlana, e ʻae ana i ka wai e kahe manuahi.

He ʻelua ʻaoʻao anei nā ʻūhā lele?

Bidirectional -means hiki ke hoʻomalu i ke kahe i nā ʻaoʻao ʻelua, E like me kā mākou i kamaʻilio ai, hiki i nā ʻōkuhi hana valves ke hiki i nā koi.
1 ʻOi aku ka waiwai ma mua o nā ʻano valve ʻē aʻe ma muli o kā lākou hoʻolālā maʻalahi a me nā mea liʻiliʻi e pono ai no ke kūkulu ʻana. Hoʻomaopopo nui ʻia ka mālama ʻana i ke kumukūʻai ma nā nui valve nui.
2 Hoʻohana maʻalahi, hoʻonohonoho a mālama ʻia, ʻo ka concenric butterfly valve maʻalahi e maʻalahi a wikiwiki hoʻi e hoʻokomo, hiki ke hōʻemi i ke kumukūʻai hana, He hoʻolālā maʻalahi, hoʻokele waiwai i loaʻa i nā wahi neʻe liʻiliʻi, a no laila ʻoi aku ka liʻiliʻi o nā wahi lole, e hōʻemi nui i kā lākou mau koi mālama.
3 ʻO ka māmā a me ka hoʻolālā paʻa a me ka liʻiliʻi liʻiliʻi o ke alo i ke alo o ka concentric butterfly valve, hiki ke hoʻokomo a hoʻohana ʻia i nā wahi i kaupalena ʻia, makemake lākou i ka liʻiliʻi liʻiliʻi e hoʻohālikelike ʻia me nā ʻano valve ʻē aʻe, e like me nā ʻīpuka a i ʻole nā ​​pahu honua, a ʻo kā lākou compactness e hoʻomaʻamaʻa i ka hoʻonohonoho ʻana a me ka hana ʻana, ʻoi aku ka nui o nā ʻōnaehana paʻa.
4 ʻO ka hana wikiwiki, hāʻawi ka hoʻolālā rotary ʻākau (90-degree) me ka wehe wikiwiki a me ka pani ʻana. He mea waiwai kēia hiʻohiʻona i nā noi kahi e pono ai ka pane wikiwiki, e like me nā ʻōnaehana pani ulia pōpilikia a i ʻole nā ​​kaʻina hana me nā koi mana pololei. ʻO ka hiki ke wehe a pani koke e hoʻonui i ka pane ʻana o ka ʻōnaehana, e hana ana i nā valve concentric butterfly kūpono loa no ka hoʻoponopono kahe ʻana a me ka mana on/off i nā ʻōnaehana e koi ana i ka manawa pane kiʻekiʻe.

ʻO ka hope, ʻo ka valve butterfly bidirectional me ke ʻano sealing ʻaoʻao ʻelua ma muli o kona ʻano elastic sealing ma waena o ka noho valve a me ka disc butterfly, e hōʻoia i ka hoʻopaʻa paʻa ʻana me ka nānā ʻole i ke kahe kahe wai.
