ʻO ka valve butterfly, ʻike ʻia hoʻi ʻo flap valve, he valve hoʻoponopono maʻalahi, hiki ke hoʻohana ʻia no ka hoʻomalu ʻana i ka ʻenehana paipu haʻahaʻa haʻahaʻa. ʻO ka valve Butterfly kahi ʻano valve nona ka ʻāpana pani (disc or butterfly plate) he diski a kaʻapuni a puni ke axis valve e wehe a pani. Hoʻohana nui ia i ka ʻoki ʻana a me ka throttling i ka pipeline. ʻO ka ʻāpana wehe a pani ʻana o ka valve butterfly he pā pelelele ʻano disc, e hoʻohuli ana a puni kona axis i loko o ke kino valve, i hiki ai ke hoʻokō 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 ʻano like ʻole corrosive a me ka noncorrosive fluid medium i ka ʻōnaehana ʻenekinia o ka generator, gas, kūlohelohe kino, liquefied petroleum gas, city gas, anu a me ka ea wela, ka hoʻoheheʻe kemika, ka hana mana a me ka pale o ke kaiapuni. Hoʻohana ʻia ia e hoʻoponopono a ʻoki i ke kahe o ka waena.
Ka hoʻohana ʻana i ka valve butterfly
He kūpono ka valve butterfly no ka hoʻoponopono kahe. E like me ka nui o ka nalo ana o ka valve butterfly i loko o ka pipeline, he ʻekolu paha ia o ka valve puka, i ke koho ʻana i ka valve butterfly, pono e noʻonoʻo pono ʻia ka hopena o ka nalo ʻana i ka ʻōnaehana pipeline, a ʻo ka paʻa o ka pā palapa 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.
Loaʻa i ka valve butterfly ka maikaʻi o ka lōʻihi o ka hale liʻiliʻi a me ke kiʻekiʻe holoʻokoʻa, ka wehe wikiwiki ʻana a me ka wikiwiki pani ʻana, a me nā hiʻohiʻona hoʻokele wai maikaʻi. ʻO ke kumu hoʻolālā o ka valve butterfly ka mea kūpono loa no ka hana ʻana i ka valve anawaena nui. Ke koi ʻia ka valve butterfly e hoʻomalu i ke kahe ʻana, ʻo ka mea nui loa ke koho pono ʻana i ka nui a me ke ʻano o ka valve butterfly.
ʻO ka maʻamau, i ka throttling, ka hoʻoponopono ʻana i ka mana a me ka medium mud, pono ka lōʻihi o ka hale pōkole a me ka wikiwiki wikiwiki a me ka wikiwiki pani (1 / 4R). ʻoki ʻoki haʻahaʻa haʻahaʻa (ʻokoʻa haʻahaʻa haʻahaʻa), ʻōlelo ʻia ka valve butterfly.
Hiki ke hoʻohana ʻia ka valve Butterfly i ka hoʻololi ʻana i ke kūlana ʻelua, ke kahawai ʻāʻī, ka leo haʻahaʻa, ka cavitation a me ka gasification, kahi liʻiliʻi o ka leakage i ka lewa a me ka abrasive medium.
I ka hoʻohana ʻana i ka valve butterfly ma lalo o nā kūlana hana kūikawā, e like me ka throttling regulation, strict sealing requirement, aahu koʻikoʻi, haʻahaʻa haʻahaʻa (cryogenic), etc., kūikawā tri eccentric a i ʻole Bi eccentric butterfly valve me kahi mea hoʻopaʻa metala kūikawā.
ʻO ka valve butterfly mid line he kūpono ia no ka wai maʻemaʻe, ka wai, ka wai kai, ka brine, ka mahu, ke kinoea maoli, ka meaʻai, ka lāʻau lapaʻau, ka aila, nā ʻakika like ʻole a me nā kumu a me nā pipeline ʻē aʻe e koi ai i ka hoʻopaʻa piha ʻana, ʻaʻohe leakage i ka hoʻāʻo kinoea, ola lawelawe kiʻekiʻe. a me ka mahana hana o - 10 ~ 150 ℃.
He kūpono ia no ka wehe ʻana a me ka pani ʻana o ka lua a me ka hoʻoponopono ʻana i ka ventila a me ka hoʻohemo ʻana i ka lepo. Hoʻohana nui ʻia ia i ka pipeline gas a me ke kahawai wai o ka metallurgy, ka ʻoihana māmā, ka mana uila a me ka ʻōnaehana petrochemical.
Metala i metala uwea sila lua eccentric butterfly valve ua kupono no ke kulanakauhale mehana, ka mahu lako, ka wai a me ke kinoea, aila, waika a me ka alkali pipelines, e like me ka hooponopono a me ka intercepting mea.
Hiki ke hoʻohana nui ʻia i ka petroleum, petrochemical, chemical, metallurgy, uila a me nā māla ʻē aʻe ma ke ʻano o ka hoʻohana ʻana i ka valve control program o ka nui PSA gas separation unit. He pani maikaʻi ia no ka valve puka a me ka valve pani.
ʻO ke kumu koho o ka valve butterfly
1. Hoʻohālikelike ʻia me ka valve puka, ʻoi aku ka nui o ka poho o ka butterfly valve, no laila ua kūpono ia no ka ʻōnaehana pipeline me ka lax pressure loss loss.
2. No ka hiki ke hoʻohana ʻia ka valve butterfly no ka hoʻoponopono kahe ʻana, kūpono ke koho ʻia i ka pipeline e pono ai ka hoʻoponopono kahe.
3. Ma muli o ka palena o ka hoʻokumu ʻana o ka valve butterfly a me ka mea hoʻopaʻa, ʻaʻole kūpono ia no ke kiʻekiʻe wela a me ka ʻōnaehana pipeline kiʻekiʻe. ʻO ka maʻamau, aia ka mahana hana ma lalo o 300 ℃ a ʻo ke kaomi nominal ma lalo o PN40.
4. No ka mea, he pōkole ka lōʻihi o ke anawaena, a hiki ke hana ʻia i loko o ke anawaena nui, no laila, i ke ʻano o nā koi 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 ʻia a pani ʻia paha ka valve butterfly e ka 90 ° rotation, ua kūpono ke hoʻohana ʻana i ka valve butterfly ma ke kahua kahi e wikiwiki ai ka wehe a me ka pani ʻana.
