ʻO ka hoʻonohonoho ʻana a me ka hana hana o ka anticorrosive fluorine plastic valve He aha ka mea e nānā pono ʻia i ka hoʻokomo ʻana i ka valve liquefied gas

ʻO ka paila anticorrosive fluorine lined plastic pump he mea maʻamau i hoʻohana ʻia no ka lawe ʻana i nā wai corrosive e like me ka waikawa, ka alkali a me ka paʻakai. I ka manawa like, i ka wā e hoʻohana ai i ka paila fluorine, pono e hoʻopili ʻia ka pipeline valve e anticorrosive. He aha ka mea e pono ai e hoʻolohe i ka hana lawelawe a me ka hoʻokomo ʻana o ka fluorine lined plastic valve? ʻO ke koho kūpono a me ka hoʻohana ʻana i ka lining fluorine plastic anti-corrosion valve, ka poʻe a pau i ka pilikia ʻenekinia, fluorine plastic anticorrosive pump a me ka valve i ka ʻaila, ʻoihana kemika, lāʻau lapaʻau, metallurgy, ʻoihana mana uila ikaika corrosive medium e like me ka mea hoʻopili acid-base. ua hoʻohana ʻia, akā no ke koho ʻana i ka maikaʻi, me ka lining fluorine plastic valves maikaʻi, e like me kā mākou mea kūʻai aku no nā makahiki he nui o ka ʻike noiʻi kahua, pono e waiho ʻia nā ʻōlelo aʻoaʻo no ka hoʻohana ʻana i ka mahana waena, ke kaomi, ka ʻokoʻa a me nā mea ʻē aʻe. nā kūlana i ka wā i koho ʻia ai ka valve anti-corrosion valve fluorine:
1, laina me ka fluorine plastic valve e hoʻohana ana i nā kūlana waena
ʻAʻole pono e loaʻa nā ʻāpana paʻakikī, nā kristal, nā haumia, a me nā mea ʻē aʻe i ke kūlana waena o ka fluorine lined plastic valve a i ʻole PTFE bellows o ka valve core a me ka noho valve i ka hana o ka wehe ʻana a me ka pani ʻana. Loaʻa nā ʻāpana paʻakikī, nā kristal, nā haumia, koho, spool, noho hiki ke hoʻohana iā Hastelloy.
2, laina me ka fluorine plastic valve mehana wela.
Hoʻopili ʻia me ka pahu fluorine plastic valve, ʻo ka fluorine plastic he F46 (FEP), ʻaʻole hiki ke hoʻohana ʻia ka mahana wela ma mua o 150 ℃ (hiki i ka mahana wela ke 150 ℃ no kahi manawa pōkole, pono e mālama ʻia ka mahana hoʻohana lōʻihi i loko o 120 ℃), inā ʻaʻole. , ka pahu o kēlā me kēia māhele lining F46 maʻalahi e palupalu, deformation, hopena i ka pahu i pani ʻia, nui leakage. Inā hoʻohana ʻia ka mahana waena no ka manawa pōkole, ʻo ka mahana ma lalo o 180 ° C, a ʻo ka mahana ma lalo o 150 ° C no ka manawa lōʻihi, hiki ke koho ʻia kekahi ʻano fluoroplastic-PFA, akā ʻoi aku ka pipiʻi o ka PFA fluoroplastic lining. ma mua o ka lining F46 i ke kumu kūʻai, a ʻo ke koho ʻana o ka mea pahū lining like.
3, ʻaʻohe pilikia ʻino.
Pono e pale aku i ka hoʻohana ʻana i ke kaomi maikaʻi ʻole i loko o ka pipeline, inā loaʻa ke kaomi maikaʻi ʻole, maʻalahi e hoʻokuʻu ʻia ka ʻōpala fluorine i hoʻopaʻa ʻia i loko o ka lua valve (drum out), peeling, e alakaʻi ana i ka wehe ʻana a me ka pani ʻana. .
4, i hoʻopaʻa ʻia me ka fluorine plastic regulating valve pono e like me ke kahe e pono ai (Cv value) koho pololei o ka nui o ka nui o ka nui.
Ke koho ʻia, e like me ka pono o ke kaʻa (Cv) a me nā ʻāpana ʻenehana ʻē aʻe e helu ʻia ka nui o ka valve e koho ʻia a me ka wehe ʻana o ka valve, e like me ka nui o ka valve, ʻoiaʻiʻo e hana i ka valve i ka wehe no kahi lōʻihi. ka manawa holo, ma lalo o ke kūlana o ka liʻiliʻi liʻiliʻi a me ke kaomi maʻamau, no laila maʻalahi ka hana ʻana i ka pahu valve a me ke koʻokoʻo valve e ka hopena o ka media a hoʻoneʻe i ka valve, ʻO ke koʻokoʻo valve i ka waena no ka manawa lōʻihi ma lalo o ka hopena, e haʻihaʻi ai ke kumu valve.
5, kaomi, ʻokoʻa ʻokoʻa pono e hoʻomalu ʻia i loko o ka pae i ʻae ʻia.
ʻOi aku ka bellows seal lined fluorine plastic regulating valve, globe valve. No ka mea, ua hana ʻia nā bellows i nā mea tetrafluoric, ʻoi aku ka nui o ke kaomi a me ka ʻokoʻa, hiki ke alakaʻi maʻalahi i ka haki ʻana o ka bellows. ʻO Bellows seal lined fluorine plastic regulating valve, ka hoʻohana ʻana i ke kaomi kūlana, nui ka ʻokoʻa o ke kaomi, hiki ke hoʻololi ʻia i PTFE packing sila.
E hoʻomaopopo i ka hoʻokomo ʻana i ka valve LPG i ke ʻano o ka valve LPG he pahu hoʻopaʻa hoʻopaʻa paʻa, no laila ke pani ʻia ka valve, pono e hoʻopili ʻia ke kaomi i ka disc valve e hoʻoikaika i ka ʻili o ka sila ʻaʻole e kahe. Ke komo ka mea waena i ka valve mai lalo mai o ka diski, ʻo ke kūʻē ʻana e lanakila ʻia e ka mana hana ʻo ia ka ikaika friction o ke kumu a me ka paʻi ʻana a me ka pahu i hana ʻia e ke kaomi o ka medium. ʻOi aku ka ikaika o ka pani ʻana i ka valve ma mua o ka ikaika o ka wehe ʻana i ka valve, no laila ua nui ke anawaena o ke kumu valve, i ʻole e hiki mai ka hewa o ka piko o luna. He aha kā mākou e hoʻolohe ai i ka wā e hoʻokomo ai i ka valve liquefied gas? Na ka Xiaobian pūnaewele o ka valve e pane iā ʻoe.
ʻO ka pahu LPG he pahu hoʻopaʻa hoʻopaʻa paʻa, no laila ke pani ʻia ka valve, pono e hoʻopili ʻia ke kaomi i ka disc e hoʻoikaika i ka ʻili o ka sila ʻaʻole e kahe. Ke komo ka mea waena i ka valve mai lalo mai o ka diski, ʻo ke kūʻē ʻana e lanakila ʻia e ka mana hana ʻo ia ka ikaika friction o ke kumu a me ka paʻi ʻana a me ka pahu i hana ʻia e ke kaomi o ka medium. ʻOi aku ka ikaika o ka pani ʻana i ka valve ma mua o ka ikaika o ka wehe ʻana i ka valve, no laila ua nui ke anawaena o ke kumu valve, i ʻole e hiki mai ka hewa o ka piko o luna. He aha kā mākou e hoʻolohe ai i ka wā e hoʻokomo ai i ka valve liquefied gas? Na ka Xiaobian pūnaewele o ka valve e pane iā ʻoe.
Nā memo no ka hoʻokomo ʻana a me ka mālama ʻana i ka valve gas liquefied:
Hiki ke hoʻokomo ʻia ka pahu pahu pahu palaoa e hoʻohana ʻia e ka huila lima a me ka lima ma kēlā me kēia kūlana i loko o ka paipu.
ʻAʻole ʻae ʻia ka hoʻohana ʻana i ka huila lima, ka lima a me ka ʻenekini hāpai no ka hāpai ʻana.
E kūlike ke kahe o ka mea waena me ke kuhikuhi o ka pua i hōʻike ʻia ma ke kino valve.
ʻO ka pahu wai wai, i ʻike ʻia ʻo ka pani puka, kahi ʻano valve i hoʻohana ʻia. He mea kaulana ia no ka mea he liʻiliʻi ka friction ma waena o ka ʻili hoʻopaʻa i ke kaʻina o ka wehe ʻana a me ka pani ʻana, ʻano lōʻihi, ʻaʻole nui ke kiʻekiʻe o ka wehe, maʻalahi e hana, mālama pono, ʻaʻole kūpono wale no ka haʻahaʻa a me ka haʻahaʻa haʻahaʻa, akā kūpono hoʻi. kaomi kiʻekiʻe. ʻO kāna kumu pani e hilinaʻi ma luna o ke kaomi pahu pahu, no laila e pili pono ka ili hoʻopaʻa paʻa a me ka ili hoʻopaʻa noho, pale i ka kahe o ka media.
ʻO ka valve LPG wale nō e ʻae i ka holo unidirectional o ka waena a loaʻa ke kuhikuhi i ka wā i hoʻokomo ʻia. ʻOi aku ka lōʻihi o kona lōʻihi ma mua o ka valve puka, i ka manawa like, nui ke kūpaʻa o ka wai, ka hana lōʻihi, ʻaʻole ikaika ka hilinaʻi ʻana.
Hoʻokaʻawale ʻia nā ʻāpana LPG i ʻekolu mau ʻāpana: pololei ma, ʻākau ʻākau a me nā kīwaha oblique honua holo pololei.
Ke wehe ʻia ka pahu LPG, ʻo ke kiʻekiʻe o ka wehe ʻana o ka disc valve he 25% ~ 30% o ke anawaena nominal, a ua hōʻea ke kahe kahe i kahi ʻano nui, e hōʻike ana ua hōʻea ka valve i kahi kūlana ākea. No laila, pono e hoʻoholo ʻia ke kūlana hāmama piha o ka valve honua e ka hahau ʻana o ka disc valve.
