ʻO nā loina koho a me nā manawa kūpono o nā kiwi lele

1.Where e pili ana ka valve butterfly

ʻO nā kīwī pēpēkupono no ka hooponopono kahe ana.Ma muli o ka nui o ka nalo ʻana o ka pahu lele i loko o ka pipeline, ʻoi aku ia ma kahi o ʻekolu manawa o ka valve puka.No laila, i ke koho ʻana i ka valve butterfly, pono e noʻonoʻo pono ʻia ka mana o ka nalo o ka puʻuwai o ka ʻōnaehana pipeline, a ʻo ka ikaika o ka pā butterfly e kū i ke kaomi o ka medium pipeline pono e noʻonoʻo ʻia ke pani ʻia.ka wahine.Eia kekahi, pono e noʻonoʻo i ka palena o ka mahana hana e hiki ai i ka mea noho valve elastic ke kū i nā wela kiʻekiʻe.

ʻO ka lōʻihi o ka lōʻihi a me ke kiʻekiʻe 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 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 e hana pono a maikaʻi.

ʻO ka maʻamau, i ka throttling, hoʻoponopono i ka mana a me ke ʻano o ka lepo, pono ka lōʻihi o ka hale e pōkole a wikiwiki ka wehe a me ka wikiwiki (1/4r).ʻoki ʻoki haʻahaʻa haʻahaʻa (ka ʻokoʻa ʻokoʻa liʻiliʻi), ʻōlelo ʻia ka valve butterfly.

I ka hihia o ka hoʻololi ʻana i ʻelua kūlana, ke ala liʻiliʻi, ka haʻahaʻa haʻahaʻa, ka cavitation a me ka vaporization, kahi liʻiliʻi o ka leakage i ka lewa, a me nā media abrasive, hiki ke hoʻohana ʻia i nā kiwi lele.

I ka hoʻohana ʻana i nā valve butterfly ma lalo o nā kūlana kūikawā e like me ka throttling regulation, strict sealing koi, ʻaʻahu koʻikoʻi, haʻahaʻa haʻahaʻa (cryogenic) a me nā kūlana hana ʻē aʻe. kiwikā.

ʻO ka valve butterfly 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 huahana like ʻole e pono ai ke hoʻopaʻa paʻa ʻana, ka leakage hoʻāʻo ʻole kinoea, nā koi ola kiʻekiʻe, a me ka mahana hana o -10~150 ℃.Acid-base a me nā paipu ʻē aʻe.

ʻO ka valve butterfly eccentric i hoʻopaʻa ʻia i hoʻopaʻa ʻia he kūpono ia no ka wehe ʻana a me ka pani ʻana a me ka hoʻoponopono ʻana o ka ventila a me ka lepo.Hoʻohana nui ʻia ia i nā pipeline gas a me nā ala wai i ka metallurgy, ka ʻoihana māmā, ka mana uila, a me nā ʻōnaehana petrochemical.

ʻO ka uea metala e hoʻopaʻa ʻia i ka lua eccentric butterfly valve he kūpono ia no ka hoʻomehana kūlanakauhale, ka mahu, ka wai a me ke kinoea, ka aila, ka waikawa a me nā paipu alkali, ma ke ʻano he mea hoʻoponopono a intercepting.

Ma waho aʻe o ka hoʻohana ʻia ʻana ma ke ʻano he puʻupuʻu hoʻoheheʻe nui (PSA) ka hoʻokaʻawale ʻana i ka polokalamu hoʻokaʻawale ʻana i ke kinoea, ʻo ka metal-to-metal surface seal triple eccentric butterfly valve hiki ke hoʻohana nui ʻia i ka petroleum, petrochemical, chemical, metallurgical, uila. mana a me nā kahua ʻē aʻe.He ʻīpuka ʻīpuka, pani pani, a me nā mea ʻē aʻe.

2. ʻO ke kumu koho o ka valve butterfly

1. No ka mea, he nui ka pohō o ke kaomi ʻana o ka valve butterfly i ka hoʻohālikelike ʻia me ka valve puka, ua kūpono ia no nā ʻōnaehana paipu me nā koi ʻoi aku ka liʻiliʻi.

2. No ka mea hiki ke hoʻohana ʻia ka valve butterfly no ka hoʻoponopono kahe ʻana, kūpono ia no ka hoʻohana ʻana i nā pipeline e pono ai ka hoʻoponopono kahe.

3. Ma muli o ka palena o ke ʻano o ka valve butterfly a me ka mea hoʻopaʻa paʻa, ʻaʻole kūpono ia no ke kiʻekiʻe wela a me ke kiʻekiʻe kiʻekiʻe.ʻO ka maʻamau, aia ka mahana hana ma lalo o 300 ℃, a ʻo ke kaomi nominal ma lalo o PN40.

4. Ma muli o ka pōkole o ka lōʻihi o ka pahu butterfly a hiki ke hana ʻia i ke anawaena nui, pono e hoʻohana ʻia ka valve butterfly i nā manawa e koi ʻia ai ka lōʻihi o ka hale e pōkole a i ʻole ke anawaena nui (e like me DN1000). a ʻoi aku paha).

5. No ka mea hiki ke wehe a pani ʻia paha ka valve butterfly ma ka hoʻololi wale ʻana i ka 90 °, ʻoi aku ka maikaʻi o ke koho ʻana i ka valve butterfly i nā manawa e pono ai ka wehe wikiwiki a me ka pani ʻana.
