Kiwikā pulelehua i hoʻopaʻa ʻia me ka popopoʻO ke kau ʻana i ka resin polytetrafluoroethylene (a i ʻole ka ʻaoʻao i hana ʻia) ma ka paia o loko o ke kila a i ʻole ka hao butterfly valve pressure-bearing a i ʻole ka ʻili o waho o nā ʻāpana o loko o ka butterfly valve ma ke ʻano hoʻoheheʻe (a i ʻole inlay). ʻO nā waiwai kūikawā o nā butterfly valves e kūʻē i nā mea corrosive ikaika e hana ʻia i nā ʻano like ʻole o nā butterfly valves a me nā kīʻaha kaomi.
I loko o nā mea anti-corrosion, loaʻa iā PTFE ka hana maikaʻi loa. Ma waho aʻe o ka metala hoʻoheheʻe ʻia, ka fluorine elemental a me nā hydrocarbons ʻala, hiki ke hoʻohana ʻia i nā ʻano like ʻole o ka waikawa hydrochloric, ka waikawa sulfuric, ka waikawa nitric, aqua regia, ka waikawa organik, ka oxidant ikaika, ka i hoʻopaʻa ʻia, ka waikawa dilute alternating, ka alkali alternating a me nā mea organik like ʻole he mau hopena random. ʻO ka uhi ʻana o ka PTFE ma ka paia o loko o ka valve butterfly ʻaʻole wale e lanakila i nā hemahema o ka ikaika haʻahaʻa o ka mea PTFE, akā e hoʻoponopono pū i ka pilikia o ke kūpaʻa ʻana i ka corrosion o nā mea kumuhana valve butterfly. Hana maikaʻi ʻole a me ke kumukūʻai kiʻekiʻe. Eia kekahi, ma waho aʻe o kona kūpaʻa kemika maikaʻi loa, loaʻa iā PTFE nā waiwai antifouling maikaʻi a me nā waiwai anti-stick, nā coefficients friction dynamic a me static liʻiliʻi loa, a me ka hana anti-friction a me ka lubrication maikaʻi. Hoʻohana ʻia ia ma ke ʻano he hui sila no ka wehe ʻana a me ka pani ʻana o nā valve butterfly, a pono e hoʻemi i ka ʻili sila. Hiki ke hoʻemi ʻia ka friction ma waena o nā valves butterfly, hiki ke hoʻemi ʻia ka torque hana o ka valve butterfly, a hiki ke hoʻomaikaʻi ʻia ke ola lawelawe o ka huahana.
Kiwikā pulelehua i uhi ʻia me ka fluorine, i ʻike ʻia hoʻi ʻo ka valve butterfly anti-corrosion, hoʻohana pinepine ʻia i nā kūlana hana ʻino, ʻo ia hoʻi nā kemika ʻawahia a me nā mea ʻino, a i ʻole nā ʻano mea hoʻoheheʻe waikawa a i ʻole nā mea hoʻoheheʻe organik. ʻO ka hoʻohana pono ʻole e hopena i nā pohō waiwai nui a me ka hopena koʻikoʻi. Hiki i ka hoʻohana pono ʻana a me ka mālama ʻana i ka valve butterfly ke hoʻolōʻihi i ke ola lawelawe o ka valve butterfly i uhi ʻia i ka fluorine, no laila he aha nā kikoʻī e hiki ke hana ʻia e pale pono ai?
1. Ma mua o ka hoʻohana ʻana, e heluhelu pono i ka manual kuhikuhi no ka valve pulelehua i uhi ʻia i ka fluorine.
2. E hoʻohana iā ia i loko o ka pae 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 i ka valve butterfly i uhi ʻia me ka fluorine mai ka hoʻoulu ʻana i ke kaumaha nui o ka pipeline ma muli o nā loli o ka mahana, e hōʻemi i nā loli o ka mahana, a e hoʻohui i nā hui hoʻonui ʻano U ma mua a ma hope o ka valve butterfly.
4. Kapu ka hoʻohana ʻana i ka lever e wehe a pani i ka valve butterfly i uhi ʻia me ka fluorine. E makaʻala i ke kūlana hōʻike wehe a pani ʻana a me ka mea palena o ka valve butterfly i uhi ʻia me ka fluorine. Ma hope o ka wehe ʻana a me ka pani ʻana, mai koi i ka valve e pani, i ʻole e hōʻino mua ʻia ka ʻili sila plastik fluorine.
5. No kekahi mau media i paʻa ʻole a maʻalahi hoʻi e palaho (no ka laʻana, ʻo ka palaho ʻana o kekahi mau media e hoʻonui ai i ka nui a hoʻonui i ke kaomi maʻamau i nā kūlana hana), kahi e hōʻino ai i ka valve butterfly a i ʻole ka leakage, pono e hana ʻia nā hana e hoʻopau a kaupalena paha i nā mea e hoʻopilikia ai i ka palaho ʻana o nā media paʻa ʻole. . I ke koho ʻana i kahi valve butterfly, pono e koho ʻia ka valve butterfly i uhi ʻia me ka fluorine me kahi mea hoʻomaha kaomi aunoa me ka noʻonoʻo ʻana i nā loli hiki ke hana i nā kūlana hana i hoʻokumu ʻia e ka palaho ʻole a maʻalahi o ka medium.
6. Noka kiwikā pulelehua i uhi ʻia i ka fluorinema ka pipeline me ka mea ʻawahia, lapalapa, pahū a me ka mea ʻino ikaika, ua kapu loa ke hoʻololi i ka ʻūlū ma lalo o ke kaomi. ʻOiai ʻo ka valve butterfly i hoʻopaʻa ʻia me ka fluorine he hana sila luna i ka hoʻolālā ʻana, ʻaʻole ia e ʻōlelo ʻia e hoʻololi i ka ʻūlū ma lalo o ke kaomi.
7. No nā paipu me ka mea puhi kūlohelohe, pono e hana ʻia nā hana e hōʻoia i ka mahana o ka ambient a me ke ʻano hana ʻaʻole e ʻoi aku ma mua o ke kiko puhi kūlohelohe o ka mea hana e pale aku ai i ka pōʻino i hoʻokumu ʻia e ka lā a i ʻole ke ahi o waho.
Mea pili: nā ʻano like ʻole o nā paʻakai waikawa-kumu a me kekahi mau mea hoʻoheheʻe organik.
