ʻO ka pāpū lele lele ʻo Fluoroplastic lined corrosion-resistant butterfly valvee kau i ka polytetrafluoroethylene resin (a i ʻole profile processed) ma ka paia o loko o ke kila a i ʻole ka hao butterfly valve ʻāpana kaomi a i ʻole ka ʻili o waho o nā ʻāpana butterfly valve i loko ma ke ʻano o ka hoʻoheheʻe ʻana (a i ʻole inlay). Hana ʻia nā ʻano ʻokoʻa like ʻole o nā kīwaha butterfly e kūʻē i ka media corrosive ikaika i nā ʻano ʻano like ʻole o nā kiwi lele a me nā moku kaomi.
I nā mea anti-corrosion, ua hoʻokō maikaʻi ʻole ʻo PTFE. Ma waho aʻe o ka metala i hoʻoheheʻe ʻia, elemental fluorine a me nā hydrocarbons aromatic, hiki ke hoʻohana ʻia i nā ʻano ʻokoʻa like ʻole o ka waika hydrochloric, sulfuric acid, nitric acid, aqua regia, organic acid, ikaika oxidant, concentrated, alternating dilute acid, alternating alkali a me nā ʻano mea like ʻole. he mau hana like ole. Lining PTFE ma luna o ka paia o loko o ka lele lele ʻaʻole i lanakila wale i nā hemahema o ka ikaika haʻahaʻa o ka PTFE mea, akā hoʻoponopono pū i ka pilikia o ka corrosion kūʻē o nā mea kumuhana butterfly valve. Hana maikaʻi ʻole a me ke kumukūʻai kiʻekiʻe. Eia kekahi, ma waho aʻe o kona kūpaʻa kemika maikaʻi loa, he mau antifouling maikaʻi a me nā waiwai anti-stick ka PTFE, liʻiliʻi liʻiliʻi liʻiliʻi a me nā coefficient friction static, a me ka hana anti-friction a me ka lubrication maikaʻi. Hoʻohana ʻia ia e like me ka hoʻopaʻa paʻa ʻana no ka wehe ʻana a me ka pani ʻana o nā kiwi lele, a pono e hōʻemi i ka ʻili o ka sila. Hiki ke hoʻemi ʻia ka friction ma waena o nā valve butterfly, hiki ke hoʻemi ʻia ka torque hana o ka valve butterfly, a hiki ke hoʻomaikaʻi ʻia ke ola lawelawe o ka huahana.
ʻO ka pāpū lele lele ʻo Fluorine, ʻike ʻia hoʻi ʻo anti-corrosion butterfly valve, hoʻohana pinepine ʻia i nā kūlana hana koʻikoʻi, nā mea ʻawaʻawa a me nā mea ʻino, a i ʻole nā ʻano corrosive nui o nā ʻano acid-base a i ʻole nā mea hoʻoheheʻe organik. ʻO ka hoʻohana pono ʻole ʻia e hopena i nā poho waiwai nui a koʻikoʻi ma muli o ka. ʻO ka hoʻohana pono ʻana a me ka mālama ʻana i ka valve butterfly hiki ke hoʻolōʻihi i ke ola lawelawe o ka valve butterfly-lined fluorine, no laila he aha nā kikoʻī e hiki ke hana i mea e pale pono ai?
1. Ma mua o ka hoʻohana ʻana, e heluhelu pono i ka ʻōlelo aʻo o ka valve butterfly-lined fluorine.
2. E hoʻohana iā ia i loko o ka laulā o ke kaomi, ka mahana a me ka waena i kuhikuhi ʻia ma ka papa inoa a i ʻole ma ka manual.
3. I ka wā e hoʻohana ʻia ai, e pale aku i ka hoʻoulu ʻana i ke koʻikoʻi pipeline ma muli o ka hoʻololi ʻana o ka mahana, e hōʻemi i ka hoʻololi ʻana o ka mahana, a e hoʻohui i nā hui hoʻonui U-like ma mua a ma hope o ka valve butterfly.
4. ʻAʻole ʻae ʻia ka hoʻohana ʻana i ka lever e wehe a pani i ka valve butterfly-lined fluorine. E nānā pono i ke kūlana hōʻailona wehe a pani ʻana a me ka hāmeʻa palena o ka valve butterfly-lined fluorine. Ma hope o ka wehe ʻana a me ka pani ʻana, mai hoʻoikaika i ka pahu e pani, e pale i ka pōʻino mua o ka fluorine plastic sealing surface.
5. No kekahi mau mea paʻa paʻa ʻole a maʻalahi hoʻi e hoʻoheheʻe ʻia (no ka laʻana, ʻo ka decomposition o kekahi mau media e hoʻonui i ka leo a hoʻonui i ke kaomi ʻokoʻa i nā kūlana hana), ka mea e hōʻino ai i ka valve butterfly a leakage paha, pono e lawe ʻia nā hana e hoʻopau ai. a i ʻole e kaupalena i nā kumu e hoʻopōʻino ai ka media paʻa ʻole. . I ke koho ʻana i ka valve butterfly, pono ke koho ʻia ka valve butterfly fluorine-lined me kahi mea hoʻoluʻu kaomi maʻalahi i ka noʻonoʻo ʻana i nā loli hiki ke hana ʻia e ka paʻa ʻole a me ka maʻalahi o ka decomposition o ka waena.
6. No ka meaʻo ka valve lele lele fluorinema luna o ka pipeline me nā mea ʻawaʻawa, ʻāʻā, pahū a me ka ikaika corrosive medium, ua kapu loa ia e pani i ka paʻi ma lalo o ke kaomi. ʻOiai ʻo ka valve butterfly-lined fluorine he hana sila i luna i ka hoʻolālā ʻana, ʻaʻole ia e ʻōlelo ʻia e hoʻololi i ka paʻi ma lalo o ke kaomi.
7. No nā paipu me ka mea hoʻoheheʻe kuʻuna, pono e hana ʻia e hōʻoia ʻaʻole hiki ke ʻoi aku ka mahana o ka ambient a me ke kūlana hana ma mua o ka wela wela o ka mea e pale ai i ka pōʻino i hana ʻia e ka lā a i ʻole ke ahi o waho.
Mea kūpono: nā ʻano ʻokoʻa o nā paʻakai acid-base a me kekahi mau mea hoʻoheheʻe organik.
