ʻO ka valve Butterfly i kapa ʻia ʻo flap valve, he ʻano maʻalahi o ka valve control, akā hiki ke hoʻohana ʻia no ka hoʻololi ʻana i ka pipeline medium switch control. ʻO ka valve Butterfly e pili ana i kahi ʻano valve nona ka ʻāpana pani (disc a disc) he diski, e kaʻapuni ana a puni ka pahu valve e wehe a pani. Hoʻohana nui ia i ka ʻoki ʻana a me ka throttling ma ka pipeline. ʻO ka ʻāpana wehe a pani ʻana o ka valve butterfly he pā pelelele i hoʻopaʻa ʻia, e hoʻololi ana a puni kona axis i loko o ke kino valve, i mea e hoʻokō ai i ke kumu o ka wehe a pani ʻana a hoʻoponopono paha. Hoʻopili ʻia ka valve Butterfly i ka pipeline e lawe ana i nā media corrosive a me ka non corrosive fluid i loko o ka generator, gas, natural gas, liquefied petroleum gas, city gas, cold and heat air, chemical smelting and power generation and environmental protection engineering systems, i hoʻohana ʻia e. hoʻoponopono a ʻoki i ke kahe o ka waena.
Ka hoʻohana ʻana i ka valve butterfly
He kūpono nā kiwi kīpē no ka hoʻoponopono kahe. Ma muli o ka nui o ka pau ʻana o ke kaomi ʻana o ka valve butterfly i loko o ka pipeline, ʻoi aku ka nui o ʻekolu mau manawa o ko ka valve gate, pono e noʻonoʻo pono ʻia ka mana o ka nalo ʻana o ke kaomi ma ka ʻōnaehana pipeline i ke koho ʻana i ka valve butterfly, a me ka paʻa ʻana o ka paʻa o ka pā pipi e lawe ana i ka pipeline. Pono e noʻonoʻo ʻia ke kaomi ʻana i ka wā pani. Eia kekahi, pono e noʻonoʻo ʻia ka palena wela hana o nā mea noho kūpaʻa i ka wela kiʻekiʻe.
ʻO ka lōʻihi o ka hale a me ke kiʻekiʻe holoʻokoʻa o ka valve butterfly he liʻiliʻi, wikiwiki ka wehe a me ka pani ʻana, a he mau hiʻohiʻona maikaʻi kona. ʻO ke kumu hoʻolālā o ka valve butterfly ka mea kūpono loa no ka hana ʻana i ka valve anawaena nui. Ke hoʻohana ʻia ka valve butterfly no ka hoʻokele kahe ʻana, ʻo ka mea nui ke koho pololei i ka nui a me ke ʻano o ka valve butterfly, i hiki ke hana pono a me ka maikaʻi.
ʻO ka maʻamau, i ka throttling, ka hoʻoponopono ʻana i ka mana a me ka medium mud, ka lōʻihi o ka hoʻolālā pōkole a me ka wehe wikiwiki a me ka wikiwiki pani (1 / 4R). ʻoki ʻoki haʻahaʻa haʻahaʻa (ka ʻokoʻa ʻokoʻa liʻiliʻi), ʻōlelo ʻia ka valve butterfly.
Hiki ke hoʻohana ʻia ka valve Butterfly i ka wā e hoʻololi ai i ke kūlana pālua, ke kahawai contraction, haʻahaʻa haʻahaʻa, cavitation a me gasification hanana, kahi liʻiliʻi o ka leakage i ka lewa, a me ka abrasive medium.
Ke hoʻohana ʻia ka valve butterfly ma lalo o nā kūlana hana kūikawā, e like me ka throttling regulation, strict sealing, aahu koʻikoʻi a me ka haʻahaʻa haʻahaʻa (hohonu hohonu), e hoʻohana ʻia ka valve butterfly kūikawā me ka hoʻolālā kūikawā metala sealing belt regulating device.
ʻO ka valve butterfly laina waena ka mea kūpono no ka wai hou, ka wai, ka wai kai, ka wai paʻakai, ka mahu, ke kinoea maoli, ka meaʻai, ka lāʻau lapaʻau, ka aila a me nā ʻano acid-base a me nā pipeline ʻē aʻe e pono ai ke hoʻopaʻa paʻa piha, zero gas test leakage, nā koi ola kiʻekiʻe. , a me ka mahana hana o – 10 ~ 150 ℃.
Hoʻohana nui ʻia ia i ka metallurgy, ka ʻoihana māmā, ka mana uila, ka pipeline gas petrochemical a me ke kahawai wai.
Metala i metala uwea sila lua eccentric butterfly valve ua kūpono no ke kūlanakauhale wela lako, mahu lako, wai a me ka kinoea, aila, waika a me ka alkali pipelines e like me ka hooponopono a me ka intercepting lako.
ʻAʻole i hoʻohana wale ʻia ka metala i ka sila metala triple eccentric butterfly valve e like me ka mana o ka papahana o ka nui o ka puʻu ʻana o ke kinoea adsorption (PSA), akā hoʻohana nui ʻia i ka petroleum, petrochemical, chemical, metallurgy, uila a me nā māla ʻē aʻe. He pani maikaʻi ia no ka valve puka a me ka valve pani.
ʻO ke kumu koho o ka valve butterfly
1. Ke hoʻohālikelike ʻia me ka ʻīpuka puka, ʻoi aku ka nui o ka nalo ʻana o ka valve butterfly, no laila ua kūpono ia no ka ʻōnaehana pipeline me ka liʻiliʻi o nā koi poho.
2. No ka mea hiki ke hoʻololi ʻia ka valve butterfly e ka kahe, ua kūpono ke koho ʻia i ka pipeline e pono ai ka hoʻoponopono kahe.
3. Ma muli o ka palena o ke kūkulu ʻana a me ka hoʻopaʻa ʻana i nā mea o ka valve butterfly, ʻaʻole kūpono ia no ke kiʻekiʻe wela a me ka ʻōnaehana pipeline kiʻekiʻe. Aia ka mahana hana maʻamau ma lalo o 300 ℃ a ʻo ke kaomi nominal ma lalo o PN40.
4. No ka mea, he pōkole ka lōʻihi o ke anawaena butterfly, a hiki ke hana ʻia i loko o ke anawaena nui, no laila i ke ʻano o ka lōʻihi pōkole a i ʻole ke anawaena nui (e like me ka ʻoi aku ma mua o DN 1000), pono e koho ʻia ka valve butterfly.
5. No ka mea hiki ke wehe a pani ʻia paha ka valve butterfly e ka 90 ° rotation wale nō, kūpono ke koho ʻana i ka valve butterfly ma ke kula me nā koi wikiwiki a me ka pani ʻana.
