Puka kupua , i ʻike ʻia ʻo flap valve, he valve hoʻoponopono maʻalahi. I ka manawa like, hiki ke hoʻohana ʻia no ka hoʻololi ʻana i ka mana o ka medium pipeline haʻahaʻa. ʻO ka valve Butterfly e pili ana i ka valve nona ka ʻāpana pani (disc a disc) he disiki a kaʻapuni a puni ka ʻāpau valve e wehe a pani. Hoʻokani nui ia i ke ʻano o ka ʻoki a me ka throttling ma ka pipeline. ʻO ka wehe ʻana a me ka pani ʻana o ka valve butterfly he pā palapa i ke ʻano diski, e hoʻohuli a puni kona axis i loko o ke kino valve, i mea e hoʻokō ai i ke kumu o ka wehe, pani ʻana a hoʻoponopono paha. Hoʻohana ʻia ka valve Butterfly i nā pipelines e lawe ana i nā ʻano like ʻole o ka corrosive a me ka noncorrosive fluid media i nā ʻōnaehana ʻenehana e like me ka generator, gas, natural gas, liquefied petroleum gas, urban gas, ea wela a me ke anuanu, hoʻoheheʻe kemika, hana mana a me ka palekana o ke kaiapuni, a hoʻohana ʻia. e hooponopono a oki i ke kahe ana o ka media.
Ka hoʻohana ʻana i ka valve butterfly
He kūpono nā kiwi kīpē no ka hoʻoponopono kahe. Ma muli o ka nui o ka nalo ʻana o ka valve butterfly i loko o ka pipeline, ʻoi aku ia ma kahi o ʻekolu mau manawa o ka valve valve, i ke koho ʻana i ka valve butterfly, pono e noʻonoʻo pono ʻia ka hopena o ka nalo ʻana o ke kaomi ma ka ʻōnaehana pipeline, a me ka paʻa ʻana o ka paʻa 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 elastic i ka wela kiʻekiʻe.
He liʻiliʻi ka lōʻihi o ka pahu butterfly a me ke kiʻekiʻe holoʻokoʻa, ka wehe wikiwiki a me ka wikiwiki o ka pani ʻana, a me nā ʻano hoʻokele wai maikaʻi. ʻO ke kumu hoʻolālā o ka valve butterfly ka mea kūpono loa no ka hana ʻana i nā kiwi nui-diameter. Ke koi ʻia ka valve butterfly e hoʻomalu i ke 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 maikaʻi.
ʻO ka maʻamau, i ka throttling, ka hoʻoponopono a me ka hoʻomalu a me ka medium mud, pono ka lōʻihi o ka hale pōkole a me ka wehe wikiwiki a me ka wikiwiki pani (1 / 4R). ʻO ke kaomi ʻoki haʻahaʻa haʻahaʻa (ke kaomi ʻokoʻa liʻiliʻi), ʻōlelo ʻia ka valve butterfly.
Hiki ke hoʻohana ʻia ka valve Butterfly i ke kahawai me ka hoʻoponopono ʻana i ke kūlana pālua a me ka ʻāʻī, haʻahaʻa haʻahaʻa, cavitation a me ka gasification, 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 a i ʻole nā ʻaʻahu koʻikoʻi, haʻahaʻa haʻahaʻa (cryogenic) a me nā kūlana hana ʻē aʻe, pono e hoʻohana i ka ʻekolu eccentric a i ʻole pālua ʻelua eccentric butterfly valve me ka metala i hoʻolālā ʻia. sila a me ka mea hooponopono.
ʻO ka valve lele waenapili i ka wai hou, ka wai, ka wai kai, brine, ka mahu, ke kinoea maoli, ka meaʻai, ka lāʻau lapaʻau, nā huahana aila, nā waikawa like ʻole a me ka alkali a me nā pipeline ʻē aʻe e pono ai ke hoʻopaʻa piha ʻana, ka leakage hoʻāʻo ʻole, ke ola lawelawe kiʻekiʻe a me ka mahana hana o - 10 ~ 150 ¡æ.
sila palupalu eccentric butterfly valve He kūpono ia no ka wehe ʻana i nā ala ʻelua, ka pani ʻana 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 ka uwea metala i hoʻopaʻa ʻia i ʻelua pahu lele lelekūpono no ka lako wela o ke kūlanakauhale, ka lako mahu, ka wai, ke kinoea, ka aila, ka waikawa a me ka alkali a me nā paipu ʻē aʻe e like me ka hoʻoponopono ʻana a me nā mea hoʻopili.
Ma waho aʻe o ka hoʻohana ʻia ʻana e like me ka ʻōnaehana hoʻokele polokalamu o ka nui o ka puʻuwai swing adsorption (PSA) hoʻokaʻawale kinoea, ʻo ka metala imetala i hoʻopaʻa ʻia i ʻekolu pahu eccentric butterfly valve hiki ke hoʻohana nui ʻia i ka ʻaila, petrochemical, kemika, metallurgy, mana 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. No ka mea, he nui ka poho o ke kaomi o ka valve butterfly i ka hoʻohālikelike ʻia me ka valve puka, ua kūpono ia no ka ʻōnaehana pipeline me ka lax pressure loss loss.
2. No ka mea hiki ke hoʻololi ʻia ka valve butterfly e ka kahe, ua kūpono ia no ke koho ʻana i ka pipeline e koi ana i ka hoʻoponopono kahe.
3. Ma muli o ka kaupalena ʻana o ka ʻōnaehana valve butterfly a me nā mea sealing, ʻaʻole kūpono ia no ke kiʻekiʻe wela a me ka ʻōnaehana pipeline kiʻekiʻe. ʻO ka mahana hana maʻamau ma lalo o 300 ¡æ a ʻo ke kaomi nominal ma lalo o PN40.
4. No ka mea, he pōkole ka lōʻihi o ka pahu butterfly a hiki ke hana ʻia i ke anawaena nui, pono e koho ʻia no nā manawa i koi ʻia ai ka lōʻihi o ka lōʻihi e pōkole a i ʻole no nā valves nui anawaena (e like me ka DN1000 ma luna aʻe).
5. No ka mea hiki ke wehe ʻia a pani ʻia paha ka valve butterfly ma ka hoʻololi ʻana i ka 90 ¡ã, kūpono ke koho ʻana i ka valve butterfly ma ke kahua me nā koi wikiwiki e wehe a pani.
