ʻEhia ka nui o nā huli e pani ai i kahi ʻūpepa Butterfly?Pehea ka lōʻihi?

No ka laʻana, inā makemake ʻoe e wehe i ka valve butterfly DN100, PN10, ʻo ka torque waiwai he 35NM, a ʻo ka lōʻihi o ka lima he 20cm (0.2m), a laila ʻo 170N ka ikaika i makemake ʻia, e like me 17kg.
ʻO ka valve butterfly he valve hiki ke wehe a pani ʻia ma ka hoʻohuli ʻana i ka pā valve 1/4 huli, a ʻo ka helu o ka huli ʻana he 1/4 huli hoʻi.A laila hoʻoholo ʻia ka manawa e pono ai e wehe a pani ʻia e ka torque.ʻO ka ʻoi aku ka nui o ka torque, ʻoi aku ka lohi o ka wehe a pani ʻana o ka valve.kaʻina ʻēkoʻa.

 

2. ʻO ka valve butterfly i hoʻohana ʻia i ka ilo:

i hoʻolako ʻia ma nā kiwi lele me DN≥50.ʻO kahi manaʻo e pili ana i ka helu o nā huli a me ka wikiwiki o ka worm gear butterfly valve i kapa ʻia ʻo "speed ratio".
ʻO ka lakio wikiwiki e pili ana i ka ratio ma waena o ka hoʻololi ʻana o ka mea hoʻoheheʻe mea hoʻoiho (handwheel) a me ka hoʻololi ʻana o ka pā kīpē lele.No ka laʻana, ʻo ka 24:1 ka nui o ka wikiwiki o ka DN100 turbine butterfly valve, ʻo ia hoʻi, ʻo ka huila lima ma ka pahu turbine e hoʻohuli i 24 mau manawa a hoʻololi ka papa pelepepa i 1 pōʻai (360°).Eia naʻe, ʻo 90° ka huina wehe kiʻekiʻe o ka pā peʻapeʻa, ʻo ia ka 1/4 pōʻai.No laila, pono e hoohuli i ka huila lima ma ka pahu turbine i 6 manawa.I nā huaʻōlelo ʻē aʻe, ʻo 24: 1 ʻo ia ka mea pono ʻoe e hoʻohuli i ka huila lima o ka turbine butterfly valve 6 e hoʻopau i ka wehe a pani ʻana paha o ka valve butterfly.

ʻO "The bravest" ka kiʻiʻoniʻoni kaulana loa a hoʻopā i ka makahiki 2023. Aia kahi kikoʻī i komo nā mea puhi ahi i ke kikowaena o ke ahi a hoʻohuli lima i ka 8,000 huli e pani i ka valve.ʻO ka poʻe ʻike ʻole i nā kikoʻī e ʻōlelo paha "ua hoʻonui loa kēia."ʻO kaʻoiaʻiʻo, ua hoʻoikaika ka mea puhi ahi i ka moʻolelo "The bravest" ma ka moʻolelo " hoʻohuli i ka valve 80,000 huli, 6 mau hola ma mua o ka pani ʻana.

Mai pīhoihoi i kēlā helu, ma ke kiʻiʻoniʻoni he ʻīpuka puka, akā i kēia lā ke kamaʻilio nei mākou e pili ana i ka valve butterfly.ʻAʻole pono ka nui o nā kipi e pani ai i ka valve butterfly o ka DN like.

I ka pōkole, ʻo ka helu o ka wehe ʻana a me ka pani ʻana a me ka manawa hana o ka valve butterfly e hilinaʻi ʻia i nā kumu he nui, e like me ke ʻano o ka actuator, medium flow rate and pressure, etc., a pono e koho ʻia a hoʻoponopono ʻia e like me ke kūlana maoli. .

Ma mua o ke kamaʻilio ʻana i ka helu o nā huli e pono ai e pani i ka valve butterfly, e hoʻomaopopo mua kākou i ka mea hana e pono ai no ka wehe ʻana i ka valve butterfly: ka mea hana.He ʻokoʻa nā helu o nā mea hoʻololi i hoʻohana ʻia no ka pani ʻana i ka valve butterfly, a ʻokoʻa hoʻi ka manawa e pono ai.

ʻO ke ʻano helu helu ʻana o ka valve butterfly e pili ana ka manawa wehe a pani ʻia o ka valve butterfly i ka manawa e hoʻopau ai ka valve butterfly mai ka hāmama a paʻa a i ʻole mai ka paʻa a hiki i ka hāmama.ʻO ka manawa wehe a me ka pani ʻana o ka valve butterfly e pili ana i ka wikiwiki o ka hana o ka mea hana, ke kaomi wai a me nā mea ʻē aʻe.

t=(90/ω)*60,

Ma waena o lākou, ʻo t ka manawa wehe a me ka manawa pani, ʻo 90 ka huina hoʻololi o ka valve butterfly, a ʻo ω ka wikiwiki angular o ka valve butterfly.

1. Hoʻohana ʻia i ka valve butterfly:

Hoʻolako maʻamau i nā ʻūhā butterfly me DN ≤ 200 (hiki i ka nui ke kiʻekiʻe ke DN 300).I kēia manawa, pono mākou e haʻi i kahi manaʻo i kapa ʻia "torque".

ʻO ka Torque e pili ana i ka nui o ka ikaika e pono ai e wehe a pani paha i kahi valve.Hoʻopili ʻia kēia torque e nā ʻano mea like ʻole, me ka nui o ka valve butterfly, ke kaomi a me nā ʻano o ka media, a me ka friction i loko o ka hui valve.Hōʻike pinepine ʻia nā koina Torque ma Newton mika (Nm).

3. Kiwikā lele lele uila:

Ua lako me DN50-DN3000.ʻO ke ʻano kūpono no nā kīwaha butterfly he mea uila ʻehā-hoʻololi (ke kihi ʻo 360 degere).ʻO ka mea nui ka torque, a ʻo ka hui ʻo Nm

Hiki ke hoʻololi ʻia ka manawa pani o ka valve butterfly uila, ma muli o ka mana, ka ukana, ka wikiwiki, a me nā mea ʻē aʻe o ka mea hana, a ʻaʻole ma mua o 30 kekona.
No laila, ʻehia ka nui o ka huli ʻana e pani ai i ka valve lele?ʻO ka wehe ʻana a me ka manawa pani o ka valve butterfly e pili ana i ka māmā holo kaʻa.ʻO ka māmā puka o kaZFA valveno nā mea uila maʻamau he 12/18/24/30/36/42/48/60 (R/min).
No ka laʻana, inā he poʻo uila me ka māmā holo o 18, a me ka manawa pani o 20 kekona, a laila ʻo ka helu o nā huli e pani ai he 6.
