ʻO ka valve Butterfly kahi ʻano valve e hoʻohana ana i ka wehe ʻana a me ka pani pani ʻana i nā ʻāpana e huli i hope a i waho ma kahi o 90° e wehe, pani a hoʻoponopono paha i ke kahe o ka waena.ʻAʻole wale ʻo Butterfly valve ka maʻalahi, ka liʻiliʻi liʻiliʻi, ke kaumaha māmā, ka hoʻohana haʻahaʻa haʻahaʻa, ka nui hoʻonohonoho liʻiliʻi, ka torque hoʻokele liʻiliʻi, ka maʻalahi a me ka wikiwiki o ka hana, akā he hana hoʻoponopono maikaʻi hoʻi a me nā hiʻohiʻona pani a hoʻopaʻa ʻia i ka manawa like.Hoʻohana nui ʻia nā kiwi kupua.
Me ka hoʻohana ʻana i ka lāʻau synthetic kūpaʻa kemika ma nā valve butterfly, ua hoʻomaikaʻi ʻia ka hana o nā valve butterfly.No ka loaʻa ʻana o nā hiʻohiʻona o ka pale ʻana i ka corrosion, erosion resistance, stable size, resilience maikaʻi, maʻalahi ka hana ʻana, a me ke kumu kūʻai haʻahaʻa, hiki ke koho ʻia ka synthetic rubber me nā waiwai like ʻole e like me nā koi noi like ʻole e hoʻokō i nā kūlana hana o nā valve butterfly.
No ka mea, hiki i ka polytetrafluoroethylene (PTFE) ke kū'ē i ka corrosion ikaika, ka hana paʻa, ʻaʻole maʻalahi i ka makahiki, haʻahaʻa haʻahaʻa haʻahaʻa, maʻalahi ke ʻano, paʻa ka nui, a hiki ke hoʻomaikaʻi ʻia kāna hana holoʻokoʻa ma ka hoʻopiha ʻana a me ka hoʻohui ʻana i nā mea kūpono e loaʻa ai ka ikaika a me ka friction.ʻO nā mea e hoʻopaʻa ai i ka valve butterfly me ka coefficient haʻahaʻa e lanakila ai i nā palena o ka rubber synthetic.No laila, ua hoʻohana nui ʻia nā mea polymer molecular kiʻekiʻe i hōʻike ʻia e ka polytetrafluoroethylene a me kā lākou hoʻopiha piha ʻana i nā mea i hoʻololi ʻia i loko o nā valve butterfly, i hiki ke hoʻomaikaʻi ʻia ka hana o nā valve butterfly.Ua hoʻomaikaʻi hou ʻia, a ua hana ʻia kahi kīwaha butterfly me ka nui o ka wela a me ke kaomi ʻana, ka hana hoʻopaʻa hilinaʻi a me ke ola lawelawe ʻoi aku ka lōʻihi.
No ka hoʻokō ʻana i nā koi o nā noi ʻoihana e like me ke kiʻekiʻe a me ka haʻahaʻa haʻahaʻa, ka ikaika o ka erosion, a me ke ola lōʻihi, ua hoʻomohala nui ʻia nā valves butterfly metal-sealed.Me ka hoʻohana ʻana i ke kūpaʻa wela kiʻekiʻe, ke kūpaʻa haʻahaʻa haʻahaʻa, ke kūpaʻa ʻana o ka corrosion ikaika, ka ikaika o ka erosion, a me ka ikaika kiʻekiʻe o nā mea hao i loko o nā kīwaha butterfly, ua hoʻohana nui ʻia nā kiwi lele i hoʻopaʻa ʻia i nā ʻoihana e like me ke kiʻekiʻe a me ka haʻahaʻa haʻahaʻa, ikaika. ka eli ana, a me ke ola loihi.Ua ʻike ʻia nā kiwi kīpē me ke anawaena nui (9~750 mm), ke kaomi kiʻekiʻe (42.0 MPa), a me ka laulā ākea ākea (-196 - 606 ° C).
Ke wehe piha ʻia ka valve butterfly, he liʻiliʻi ke kahe kahe.Ke wehe ʻia ka wehe ʻana ma waena o 15 ° ~ 70 °, hiki iā ia ke hana i ka mana kahe ʻana, no laila ma ke ʻano o ka hoʻoponopono nui-diameter, he mea maʻamau ka hoʻohana ʻana i nā kīwaha butterfly.
Ma muli o ka holoi ʻana o ka neʻe ʻana o ka pā peʻapeʻa, hiki ke hoʻohana ʻia ka hapa nui o nā kiwi lele no ka media me nā ʻāpana paʻa paʻa.Ma muli o ka ikaika o ka sila, hiki ke hoʻohana ʻia no ka media powdery a granular.
He kūpono nā kiwi kīpē no ka hoʻoponopono kahe.Ma muli o ka nui o ka nalo o ka pahu lele i loko o ka paipu, ma kahi o ʻekolu mau manawa o ka valve puka, i ke koho ʻana i kahi valve butterfly, pono e noʻonoʻo pono ʻia ka mana o ka nalo ʻana i ka ʻōnaehana pipeline, a me ka ikaika o ka pahu. e noʻonoʻo pono ʻia ka pā peʻapeʻa e kū i ke kaomi ʻana o ka paipu i ka wā e pani ʻia ai..Eia kekahi, pono e noʻonoʻo ʻia ka palena o ka wela hana o ka mea noho elastic 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 nā kiwi nui-diameter.Ke koi ʻia ka valve butterfly e hoʻohana ʻia no ka hoʻokele kahe ʻana, ʻo ka mea nui ke koho pololei i ka kikoʻī a me ke ʻano o ka valve butterfly i hiki ke hana pono a maikaʻi.
ʻO ka mea maʻamau, ʻōlelo ʻia nā kīwaha butterfly no ka throttling, ka hoʻoponopono hoʻoponopono a me ka media lepo kahi e koi ʻia ai ka lōʻihi pōkole, ka wehe wikiwiki a me ka wikiwiki pani ʻana, a me ka ʻoki haʻahaʻa haʻahaʻa (ʻokoʻa liʻiliʻi liʻiliʻi).Hiki ke koho ʻia nā kīwaha Butterfly no ka hoʻololi ʻana i nā kūlana ʻelua, nā kahawai i hoʻemi ʻia, ka walaʻau haʻahaʻa, ka cavitation a me ka vaporization, kahi liʻiliʻi o ka leakage i ka lewa, a me ka media abrasive.Hoʻoponopono throttle ma lalo o nā kūlana hana kūikawā, a i ʻole nā kūlana hana e koi ai i ka sila paʻa, ʻaʻahu koʻikoʻi, haʻahaʻa haʻahaʻa (cryogenic) a pēlā aku.
