Ka hopena o ka wela a me ke kaomi ʻana i ka hana ʻana o ka balve butterfly
He nui nā mea kūʻai e hoʻouna mai iā mākou i nā nīnau, a e pane mākou iā lākou e hāʻawi i ke ʻano waena, ka mahana wela a me ke kaomi, no ka mea, ʻaʻole pili wale kēia i ke kumukūʻai o ka valve butterfly, akā he kumu nui hoʻi ia e pili ana i ka hana o ka valve butterfly.ʻO kā lākou hopena i ka valve butterfly he paʻakikī a paʻa.
1. Ka hopena o ka Mahana ma ka hana ʻana o ka ʻūpā ʻo Butterfly:
1.1.Na waiwai waiwai
Ma nā wahi wela wela, pono e loaʻa i nā mea e like me ka butterfly valve body a me ka valve stem ke kū maikaʻi i ka wela, i ʻole e hoʻopilikia ʻia ka ikaika a me ka paʻakikī.Ma kahi haʻahaʻa haʻahaʻa haʻahaʻa, e lilo ka mea kino valve i palupalu.No laila, pono e koho ʻia nā mea hoʻoheheʻe wela wela no nā wahi wela kiʻekiʻe, a pono e koho ʻia nā mea me ka paʻakikī pale anu maikaʻi no nā kaiapuni haʻahaʻa haʻahaʻa.
He aha ka pālākiō wela no ke kino valve butterfly?
ʻO ka pahu lele lele hao: -10 ℃ a 200 ℃
WCB butterfly valve: -29 ℃ a 425 ℃.
ʻO ka valve lele SS: -196 ℃ i 800 ℃.
LCB lele lele: -46 ℃ i 340 ℃.
1.2.Hana Sila
ʻO ka wela kiʻekiʻe e hoʻonāwaliwali, hoʻonui a hoʻololi i ka noho valve palupalu, sealing ring, etc.ʻoiai ʻo ka haʻahaʻa haʻahaʻa hiki ke paʻakikī i ka mea hoʻopaʻa paʻa, e hopena i ka emi ʻana o ka hana sila.No laila, i mea e hōʻoiaʻiʻo ai i ka hana hoʻopaʻa ʻana ma nā wahi wela kiʻekiʻe a haʻahaʻa paha, pono e koho i nā mea hoʻopaʻa i kūpono no nā wahi wela kiʻekiʻe.
Aia ma hope iho ka laulā wela hana o ka noho valve palupalu.
• EPDM -46 ℃ - 135 ℃ Anti-kahiko
• NBR -23 ℃-93 ℃ Paʻa ʻaila
• PTFE -20 ℃-180 ℃ Ke kūʻē i ka ʻino a me nā mea hoʻoheheʻe kemika
• VITON -23 ℃ - 200 ℃ Anti-corrosion, pale wela kiʻekiʻe
• Silica -55 ℃ -180 ℃ Pale wela kiʻekiʻe
• NR -20 ℃ - 85 ℃ Kiʻekiʻe elasticity
• CR -29 ℃ - 99 ℃ Paʻa ʻaʻahu, kū i ka wā kahiko
1.3.Ka ikaika hana
Manaʻo wau ua lohe nā kānaka a pau i ka manaʻo i kapa ʻia ʻo "thermal expansion and contraction".ʻO ka hoʻololi ʻana i ka wela ke hoʻololi ʻia a i ʻole nā māhā i nā hui valve butterfly, bolts a me nā ʻāpana ʻē aʻe.No laila, i ka hoʻolālā ʻana a me ka hoʻokomo ʻana i nā valve butterfly, pono e noʻonoʻo i ka hopena o ka hoʻololi ʻana o ka mahana ma ke ʻano o ka valve butterfly, a e hana i nā ʻano kūpono e hōʻemi i ka hopena o ka hoʻonui ʻana a me ka hoʻohaʻahaʻa.
1.4.Hoʻololi i nā ʻano kahe
Hiki i nā loli wela ke hoʻololi i ka mānoanoa a me ka viscosity o ka mea hoʻoheheʻe wai, a laila e pili ana i nā ʻano kahe o ka valve butterfly.Ma nā noi kūpono, pono e noʻonoʻo ʻia ka hopena o ka hoʻololi ʻana o ka mahana ma nā ʻano kahe e hōʻoia i ka hiki ke hoʻokō i ka valve butterfly i nā pono no ka hoʻoponopono ʻana i ke kahe ma lalo o nā ʻano wela like ʻole.
2. Ka hopena o ke kaomi ʻana i ka hana ʻana o ka pāpaʻi kipi
2.1.Hoʻokō sila
Ke piʻi aʻe ka puʻe o ka wai, pono ke kū ʻana o ka valve butterfly i kahi ʻokoʻa ʻoi aku ka nui.I loko o nā kaiapuni kiʻekiʻe, pono e loaʻa i nā kīwaha butterfly ka hana sila e hōʻoia i ka hiki ʻole o ka leakage ke pani ʻia ka valve.No laila, hana pinepine ʻia ka ʻili o nā valve butterfly me ka carbide a me ke kila kila e hōʻoia i ka ikaika a me ke kūpaʻa ʻana o ka ʻili.
2.2.Ka ikaika hana
ʻO ka valve Butterfly I loko o kahi kaiapuni kiʻekiʻe, pono e kū i ka valve butterfly i ke kaomi ʻoi aku ka nui, no laila pono i ka mea a me ke ʻano o ka valve butterfly e lawa ka ikaika a me ka rigidity.ʻO ke ʻano o ka valve butterfly ka mea maʻamau e pili ana i ke kino valve, ka pā valve, ke kumu valve, ka noho valve a me nā mea ʻē aʻe.ʻAʻole lawa ka ikaika o kekahi o kēia mau mea hiki ke hoʻopau i ka valve butterfly ma lalo o ke kaomi kiʻekiʻe.No laila, pono e noʻonoʻo i ka mana o ke kaomi i ka wā e hoʻolālā ai i ka ʻōnaehana valve butterfly a lawe i nā mea kūpono a me nā ʻano hana.
2.3.Ka hana ʻana o ka valve
Hiki paha i ke kaiapuni kiʻekiʻe ke hoʻopili i ka torque o ka valve butterfly, a makemake paha ka valve butterfly i ka ikaika hana e wehe a pani paha.No laila, inā he kiʻekiʻe ke kiʻekiʻe o ka valve butterfly, ʻoi aku ka maikaʻi o ke koho ʻana i ka uila, pneumatic a me nā mea hana ʻē aʻe.
2.4.Pilikia o ka leakage
I loko o nā kaiapuni kiʻekiʻe, piʻi ka pilikia o ka leakage.Hiki i nā liʻiliʻi liʻiliʻi ke alakaʻi i ka ikehu a me nā pōʻino palekana.No laila, pono e hōʻoia i ka hana hoʻopaʻa paʻa maikaʻi o ka valve butterfly i nā wahi kiʻekiʻe e hōʻemi i ka hopena o ka leakage.
2.5.Kūleʻa kahe waena
He hōʻailona koʻikoʻi o ka hana ʻana o ka valve.He aha ke kūpaʻa kahe?E pili ana ia i ke kū'ē i loaʻa i ka wai e hele ana ma ka valve.Ma lalo o ke kaomi kiʻekiʻe, piʻi ka paʻi o ka mea waena ma ka pā valve, e koi ana i ka valve butterfly e loaʻa i ka mana kahe kiʻekiʻe.I kēia manawa, pono e hoʻomaikaʻi ka valve butterfly i ka hana kahe a hoʻemi i ka pale ʻana.
Ma keʻano laulā, he nui ka hopena o ka mahana a me ke kaomi i ka hana o ka valve butterfly, e like me ka hana sealing, ka ikaika o ka hana, ka valve valve, a me nā mea'ē aʻe. nā mea kūpono, ka hoʻolālā ʻana a me ka hoʻopaʻa ʻana, a e hana i nā ʻano kūpono e hoʻokō ai i nā loli o ka mahana a me ke kaomi.
