He aha ke ʻano o ke kila kila kila?
Abstract: Hōʻike pōkole kēia ʻatikala i ka loina hana, nā ʻāpana, nā mea maikaʻi a me nā hemahema, a me nā pilikia hewa maʻamau o nā kiwi lele kila kila, me ka manaʻo e kōkua i ka poʻe a pau e aʻo maikaʻi e pili ana i nā kiwi lele kila kila.
ʻO nā kiwi lele kila kila (ʻike pū ʻia ʻo nā kiwi flap stainless steel) he mau kiwi e hoʻohana ana i nā ʻāpana ʻano disc e pānaʻi ma 90° e wehe, pani, a hoʻoponopono i nā kahawai wai. Ma ke ʻano he ʻāpana i hoʻohana ʻia e ʻike ai i ka on-off a me ka hoʻokele kahe o nā ʻōnaehana pipeline, hiki ke hoʻohana ʻia nā ʻūhā butterfly stainless steel e hoʻokele i ke kahe o nā ʻano wai like ʻole e like me ka ea, ka wai, ka mahu, nā media corrosive like ʻole, ka lepo, nā huahana aila, nā metala wai, a me nā pāpaho radioactive. Hoʻohana nui lākou i ka ʻoki ʻana a me ka throttling ma nā pipeline. Ua hoʻohana nui ʻia nā kīwī pēpē kila kila ma nā ʻano he nui e like me ka petroleum, ʻoihana kemika, metallurgy, a me ka hydropower.
ʻO ka loina hana o nā kiwikā lele lele

ʻO nā kiwipa lele kila kila, ʻike ʻia hoʻi ʻo nā kiwi flap stainless steel, he kila kila kila maʻalahi hiki ke hoʻohana ʻia no ka hoʻomalu ʻana o ka media pipeline haʻahaʻa. Hoʻokumu nui ʻia ia me kahi kino valve, kahi pahu pahu, kahi pā lele, a me ke apo hoʻopaʻa. ʻO ke kino valve he cylindrical, me ka lōʻihi axial pōkole a me kahi pā papale i kūkulu ʻia.
ʻO ke kumumanaʻo hana o ka valve butterfly stainless steel ka mea e hoʻokō ai i ke kumu o ka wehe a pani ʻana a i ʻole ka hoʻoponopono ʻana ma o ka ʻāpana wehe a pani ʻia (kahi pā pelelele ʻano diski) e hoʻohuli ana a puni kona axis i loko o ke kino valve.
Nā Pōmaikaʻi a me nā pōʻino o ka Valve Butterfly Steel
Nā pono
1. ʻO ka torque hana liʻiliʻi, maʻalahi a me ka wikiwiki o ka wehe ʻana a me ka pani ʻana, 90 ° reciprocating rotation, labor-saving, small fluid resistance, a hiki ke hana pinepine ʻia.
2. Hoʻolālā maʻalahi, wahi hoʻokomo liʻiliʻi a me ke kaumaha māmā. ʻO ka lawe ʻana i ka DN1000 ma ke ʻano he laʻana, ʻo ke kaumaha o ka valve kila kila ma kahi o 2T ma lalo o nā kūlana like, aʻo ke kaumaha o ka valve kila kila ma kahi o 3.5T.
3. He mea maʻalahi ka huila butterfly e hui pū me nā mea hoʻokele like ʻole a maikaʻi ka lōʻihi a me ka hilinaʻi.
4. E like me ka ikaika o ka ili hoʻopaʻa, hiki ke hoʻohana ʻia no ka media me nā ʻāpana paʻa paʻa i hoʻokuʻu ʻia, a me ka pāpaʻi paʻa a me ka granular.
5. ʻO ka pahu valve he hale ma waena o ke kumu, i hoʻonāukiʻia a loaʻa iā ia nāʻano mechanical piha maikaʻi, ka paleʻana i kaʻino, a me ke kū'ēʻana. Ke wehe ʻia a pani ʻia ka valve butterfly, huli wale ke kumu o ka valve ma mua o ka hāpai ʻana a me ka hoʻohaʻahaʻa ʻana. ʻAʻole maʻalahi ka pōʻino o ka hoʻopili ʻana o ke kumu valve a hilinaʻi ke sila.
Nā pōʻino
1. He liʻiliʻi ke kaomi hana a me ke ana wela hana, a aia ka mahana hana maʻamau ma lalo o 300 ℃ a ma lalo o PN40.
2. He ʻilihune ka hana hoʻopaʻa ʻana, ʻoi aku ka maikaʻi ma mua o nā kiwi pōpō kila kila a me nā kiwi hoʻomaha kila. No laila, hoʻohana ʻia ia i nā wahi haʻahaʻa haʻahaʻa kahi i kiʻekiʻe ʻole ai nā koi sila.
3. ʻAʻole nui ka laulā hoʻoponopono kahe. Ke hiki i ka weheʻana i ka 30%, ke kahe e komo ma mua o 95%;
