ʻO ka nui o ka nui o nā pahu lele e pili ana i nā valves butterfly me ke anawaena ʻoi aku ka nui ma mua o DN500, pili pinepine ʻia e nā flanges, wafers.ʻElua ʻano o nā ʻūhā lele lele nui: concentric butterfly valve a me eccentric butterfly valve.
Pehea e koho ai i ka valve butterfly nui nui?
1. Ke liʻiliʻi ka nui o ka valve ma mua o DN1000, aia ke kaomi hana ma lalo o PN16, a ʻo ka mahana hana ma lalo o 80 ℃, ʻoi aku ka maʻamau no ka concentric line butterfly valve e ʻoi aku ka waiwai.
2. ʻO ka mea maʻamau, ke ʻoi aku ka nui o ke anawaena ma mua o 1000, paipai mākou i ka hoʻohana ʻana i ka valve butterfly eccentric, i hiki ke hoʻemi pono ʻia ka torque o ka valve ma muli o ke kihi eccentric o ka valve, kahi kūpono i ka wehe a me ka pani ʻana o ka pahu. kiwikā.Eia kekahi, hiki i ka eccentric butterfly valve ke hōʻemi a hoʻopau paha i ka friction ma waena o ka pā valve a me ka noho valve ma muli o ke kihi eccentric, a hoʻomaikaʻi i ke ola lawelawe o ka valve.
3. I ka manawa like, ʻo ka hoʻokomo ʻana i nā noho metala e hoʻomaikaʻi i ka mahana a me ke kūpaʻa paʻa o nā kiwi lele a hoʻonui i ka laulā noi o nā kiwi.No laila, hiki ke ho'ohana 'ia ka valve butterfly anawaena nui i loko o nā kūlana ha'aha'a e like me ka wai, a'o ka valve butterfly eccentric hiki ke ho'ohana 'ia ma nā wahi me nā kūlana hana pa'akikī.

Ma hea kahi i hoʻohana ʻia ai ʻo Big Size Butterfly valve
Hoʻohana ʻia nā valve butterfly nui ma kahi ākea o nā noi ʻoihana kahi e koi ʻia ai kahi kahe kahe nui.ʻO kekahi mau noi maʻamau no nā valve butterfly nui:
1. Nā mea kanu hoʻomaʻemaʻe wai: Hoʻohana maʻamau ʻia nā kīwaha butterfly i nā hale mālama wai e hoʻomalu i ke kahe o ka wai ma o nā paipu nui.
2. Nā mea kanu mana: Hoʻohana ʻia nā kīwī Butterfly i nā mea kanu mana e hoʻomalu i ke kahe o ka wai a i ʻole ka mahu ma o nā paipu e hānai ai i nā turbines.
3. Nā mea kanu hana kemika: Hoʻohana ʻia nā kīwaha Butterfly i nā mea kanu hana kemika e hoʻomalu i ke kahe o nā kinikona ma o nā paipu.
4. ʻOihana ʻaila a me ke kinoea: Hoʻohana ʻia nā valve Butterfly i ka ʻoihana ʻaila a me ke kinoea e hoʻokele i ke kahe ʻana o ka aila, kinoea, a me nā wai ʻē aʻe ma o nā pipeline.
5. Pūnaehana HVAC: Hoʻohana ʻia nā valve Butterfly i nā ʻōnaehana hoʻomehana, ea, a me ka ea ea (HVAC) e hoʻomalu i ke kahe ʻana o ka ea ma o nā auwai.
6. ʻOihana meaʻai a me nā mea inu: Hoʻohana ʻia nā valve butterfly i ka ʻoihana meaʻai a me nā mea inu e hoʻomalu i ke kahe o nā wai a me nā kinoea ma o nā lako hana.
ʻO ka holoʻokoʻa, hoʻohana ʻia nā valve butterfly nui i kekahi noi kahi e pono ai ke kaohi ʻana o ka kahe kahe nui a pani koke a me ka maikaʻi.
He aha ke ʻano o nā mea hoʻokele e hoʻohana mau ʻia no nā kiwi lele lele nui-diameter?
1.Worm Gear-Ua kūpono ka mea ilo no nā kiwi lele lele nui.A he koho waiwai a palekana, ʻAʻole pono e hilinaʻi i ke kaiapuni pūnaewele, lawa ka lumi e hana ai.Hiki i ka pahu worm gear ke hoʻonui i ka torque, akā e hoʻolohi i ka wikiwiki hoʻololi.Hiki ke hoʻopaʻa paʻa ponoʻī ʻo Worm gear butterfly valve a ʻaʻole e hoʻohuli i ke kaʻa.Aia paha kahi hōʻailona kūlana.
2.Pono e hāʻawi i ka wiliwila ʻo Electric Actuator-Electric nui-diameter butterfly valve e hāʻawi i ka volta ala hoʻokahi a i ʻole ʻekolu-phase volta ma ka pūnaewele, maʻamau he ala hoʻokahi ala uila o 22V, ʻekolu-phase voltage o 380V, maʻamau ka ʻoi aku ka maikaʻi o nā hōʻailona. Rotork.Hoʻohana ʻia i nā noi hydropower, nā noi metallurgical, nā noi kai, nā meaʻai a me nā noi lāʻau lapaʻau, etc.
3.Hydraulic Actuator-ʻO ka valve hydraulic butterfly valve nui me ka hydraulic station, ʻo kāna mau mea maikaʻi he haʻahaʻa haʻahaʻa, hana paʻa a hilinaʻi, hana palekana, a me ka hiki ke wehe a pani koke.
4.Pneumatic Actuator-Nui Pneumatic butterflykoho i ekolu eccentric multi-level metala paakiki sila pepeke valve, he kiʻekiʻe wela kū'ē, maʻalahi, oluolu e wehe a pani, a paa paa.Nui-diameter butterfly valve actuator, e like me ka paena hana kūlana e hana ai i kahi koho.Hydraulic mana hoʻohana 'ia ma ka laulā hydropower mea kanu..ka mea i hoʻohana nui ʻia i ka ʻoihana metallurgical ma ka blast furnace gas pipeline system e pale aku i ke kinoea tempering i ka paipu.
ʻO ka hoʻohana ʻana i ka valve butterfly nui
Hoʻohana nui ʻia ka valve lele lele nui i ka ʻōnaehana hoʻomehana mana a me ka catalytic cracking main fan duct system a me ke kila, metallurgy, kemika a me nā ʻōnaehana ʻoihana ʻē aʻe, a me ka mālama ʻana i ke kaiapuni, mālama wai, kiʻekiʻe kiʻekiʻe kiʻekiʻe hale lako wai a me ka paipu wai. no ka ʻoki ʻana a i ʻole ka hoʻoponopono ʻana i ke kuleana kahe.
E like me ke koho o nā mea hiki ke hoʻohana 'ia i non-corrosive kūlana kalapona kila: -29 ℃ ~ 425 ℃ kuhiliʻole kila: -40 ℃ ~ 650 ℃;e pili ana i ka media no ka ea, ka wai, ka wai, ka mahu, ke kinoea, ka aila, etc. Uila flange type paakiki sila butterfly kiwi no ka metala paakiki sila pepe kiwipa, me ka hoʻohana holomua multi-level ekolu eccentric hale, ua haku ia o DZW uila actuator Flange mea. metala paakiki sila pepeke kiwi.ʻO ka pae kaomi PN10-25=1.02.5MPa;kaliber: DN50-DN2000mm.mea: WCB hoolei kila kalapona kila;304 kila kuhiliʻole/316 kuhiliʻole kila/304L kuhiliʻole kila/316L kuhiliʻole kila.
ʻO ke anawaena nui o ka pahu lele lele he ʻano hoʻopaʻa hoʻopaʻa hilinaʻi no ka ʻoki ʻana o ka media ʻelua ala, ʻaʻohe ona leakage;ʻaʻole pono e wehe i ka valve mai ka pipeline e pani i ka sila (ʻoi aku ka nui ma mua o DN700);nā bearings no ka lubricating bearings, ʻaʻohe ʻaila ʻaila, haʻahaʻa haʻahaʻa;vertical, horizontal elua ano o ka hoonoho ana, e like me ka pono o ka lako;kino kiwi, hiki ke hoʻohana ʻia nā mea pālolo papale i ka hao hao, e hoʻopili ai i ka media kai.
