He ʻelua ʻaoʻao nā ʻūhā pepeke?

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 kinoea), Eia naʻe, ʻo kahi ʻano maikaʻi a me ka hana butterfly valve pono e hoʻolako i kahi sila maikaʻi. . He ʻelua ʻaoʻao anei nā kiwi lele? ʻO ka maʻamau, hoʻokaʻawale mākou i ka valve butterfly i nā valve butterfly Concentric a me nā 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 noho a i ʻole zero-offset butterfly valves, ʻo kā lākou mau ʻāpana he: kino Valve, disc, noho, kumu a me ke sila. Aia ke kumu a i ʻole ke kumu i waenakonu o ka diski. 'O ia ke 'ano o ka disc i loko o kahi noho palupalu, Hiki i ka mea noho ke ho'okomo i ka EPDM, NBR Viton Silicon Teflon Hypalon a i 'ole 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 ʻia ke kumu e hoʻohuli i ka disk e wehe a pani paha i ka pahu, I ka wā e hoʻohuli ai ka pahu, huli ka diski i ke kūlana hamama a i ʻole ʻāpana wehe, e ʻae ana i ka wai e kahe manuahi. Ma ke kūlana pani, hoʻololi ʻo Shaft i ka disc e pale i ke kahe holoʻokoʻa a hoʻopaʻa i ka valve.

He ʻelua ʻaoʻao anei nā kiwi 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 maikaʻi 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, hoʻolālā waiwai i loko o nā wahi neʻe liʻiliʻi, a no laila ka liʻiliʻi o nā wahi lole, e hōʻemi nui i kā lākou mālama. koi.
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 i nā ʻano valve ʻē aʻe, e like me ka puka a i ʻole nā ​​kīwaha honua, a maʻalahi ko lākou compactness. ʻo ka hoʻokomo ʻana a me ka hana ʻana, ʻo ia hoʻi ma nā ʻōnaehana paʻa 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.
