Loaʻa pinepine ka valve palekana i ka hoʻoholo hewa a me ka mālama ʻana i nā ʻōlelo aʻoaʻo e hoʻohana ai i ka valve lining fluorine

Loaʻa pinepine ka valve palekana i ka hoʻoponopono hewa a me ka mālama ʻana
1. Mai wehe i ka wā i kuhikuhi ʻia ai ke kaomi
ʻO ke kumu o kēia kūlana no ka pololei ʻole o ke kaomi mau. Pono e hoʻoponopono hou ʻia ke kaomi ʻana o ka pūnāwai a i ʻole ke kūlana o ka hāmare; Pili ka diski i ka noho. Pono e ho'āʻo maʻamau ka pahu palekana i ka ea a i ʻole ka wai; Hoʻopaʻa ʻia ka lever valve palekana ʻano lever a hoʻoneʻe ʻia ka hāmare kaumaha. Pono e hoʻoponopono hou ʻia ke kaumaha a neʻe wale ka lever.
2, emi iho ma mua o ke kaomi i hoakakaia e wehe
ʻAʻole pololei ke kaomi nui; E emi ana ka elasticity punawai kahiko. Pono e hoʻopaʻa pono ʻia ka wili hoʻoponopono a i ʻole ka punawai.
3. ʻAʻole hoʻi ka diski i ka noho ma hope o ka hoʻokuʻu ʻana
ʻO ka kumu nui kēia ma muli o ke kumu piko o ka puna, ʻaʻole pololei a paʻa paha ke kūlana hoʻonohonoho disc. Pono e hui hou.
4, lele alapine disc a haʻalulu paha
ʻO ke kumu nui, ʻo ia ka nui o ka ʻoʻoleʻa o ka puna. Pono e hoʻohana ʻia ka pūnāwai me ka ʻoʻoleʻa kūpono; ʻAʻole i hoʻoponopono pono ʻia ka pōʻai hoʻoponopono, no laila ua kiʻekiʻe ke kaomi. Pono e hoʻoponopono houʻia ke kūlana o ke apo hoʻoponopono; ʻOi aku ka nui o ke kūʻē ʻana o ka paipu hoʻokuʻu, e hopena i ka nui o ka hoʻokuʻu hope. Pono e hoʻemi ʻia ke kūʻē ʻana o ka pipeline.
5. Ke piʻi mau nei ke kaomi ma hope o ka pau ʻana
ʻO kēia ka mea nui no ka mea ke koho ʻana i ka hoʻoneʻe ʻana o ka pahu palekana Xiaoping mea hoʻokuʻu palekana, pono e koho hou ʻia i ka valve palekana kūpono; ʻO ka laina waena a i ʻole ka puna puna, i hiki ʻole ke wehe ʻia ka disc i ke kiʻekiʻe kūpono, pono e hui hou ʻia ke kumu a hoʻololi paha i ka pūnāwai; Inā ʻaʻole lawa ka ʻoki ʻana i ka paipu hoʻopau, pono e hoʻopaʻa ʻia ka paipu hoʻopau i ka laina me ka wahi hoʻokuʻu palekana.
6, leakage
Ma lalo o ke kaomi hana maʻamau o nā mea hana, ʻoi aku ka leakage ma waena o ka disc a me ka ʻili hoʻopaʻa o ka noho ma mua o ke degere ʻae ʻia. ʻO ke kumu: aia ka lepo ma waena o ka disc valve a me ka ʻili o ka noho. Hiki ke hoʻohana i ka wīwī hāpai e wehe i ka valve i nā manawa he nui, holoi ʻia ka lepo; Poino i ka ili ili. Pono e hoʻoponopono ʻia ma ka wili ʻana a wili paha ma hope o ka huli ʻana e like me ke kiʻekiʻe o ka pōʻino. ʻO ke kuʻi ʻana o ke kumu, hili ʻana, a i ʻole ka lever a me ka fulcrum deflection, ka hopena i ka spool a me ka disc misalignment. Pono e hui hou a hoʻololi paha; Hoʻemi a nalowale ka elasticity puna. Pono e lawe ʻia nā ana e like me ka hoʻololi ʻana i ka pūnāwai a me ka hoʻoponopono hou ʻana i ke kaomi wehe.
Nā ʻōlelo aʻoaʻo no ka hoʻohana ʻana i nā kiwi fluorine
ʻO nā hiʻohiʻona nui o ka fluorine lined valve:
ʻO ka mea mua, ka hana kemika fluorine lined valve:
ʻO ke kūpaʻa kahiko o ka lewa: ka pale ʻana i ka radiation a me ka haʻahaʻa haʻahaʻa: ʻike lōʻihi i ka lewa, ʻaʻole i loli ka ʻili a me nā waiwai.
ʻAʻole hiki ke hoʻopau ʻia: ka helu helu palena oxygen ma lalo o 90.
ʻAkika a me ke kūpaʻa alkaline: hiki ʻole ke hoʻoheheʻe ʻia i nā waikawa ikaika, nā kumu a me nā mea hoʻoheheʻe organik.
Ke kū'ē i ka oxidation: kū'ē i ka corrosion e nā oxidants ikaika.
ʻElua mau hiʻohiʻona hana fluorine lined valve:
Hana: ʻO ka mahana hana maʻamau: -100 ℃ ~ -150 ℃
ʻO ke kaomi hana maʻamau: ke kaomi maikaʻi: 2.5mpa, ke kaomi ʻino i ka lumi wela 70KPa
Corrosion kū'ē: kila PTFE composite paipu, i ka hoʻoheheʻe 'ia me ka lithium metala, potassium, sodium, chlorine trifluoride, oxygen trifluoride i ke kiʻekiʻe wela, kiʻekiʻe kahe kahe wai fluorine, hiki ke pale aku kokoke i na mea a pau kemika Media, me concentrated nitric acid a me ka wai aliʻi corrosion. , hiki ke hana i ka mahana o 230 ℃-250 ℃ no ka manawa lōʻihi. ʻO ke kila polyvinylidene fluoride a i ʻole nā ​​mea ʻē aʻe vinylidene fluoride composite paipu, halogen, halogenated hydrocarbons, oxidants ikaika, wai paila, alkali, nā ʻano mea hoʻoheheʻe kūlohelohe maikaʻi i ka corrosion kūpaʻa, akā ʻaʻole kū i ka uahi sulfuric acid, concentrated hot sulfuric acid a me nitric acid, ketones , esters, amines a me ka wela wela sulfonating agent corrosion ma luna o 90 ℃.
ʻO nā pono nui o ka fluorine lined valve:
ʻO ka mahana hana pale wela kiʻekiʻe a hiki i 250 ℃
ʻO ke kūpaʻa haʻahaʻa haʻahaʻa me ka ikaika mechanical maikaʻi; ʻOiai ke hāʻule ka mahana i -196 ℃, hiki ke mālama ʻia ka elongation o 5%.
ʻO ka pale ʻana i ka corrosion i ka hapa nui o nā kemika a me nā solvents, e hōʻike ana i ka inertia, ka waikawa ikaika a me ka alkali, ka wai a me nā ʻano mea hoʻoheheʻe organik.
Kūleʻa ka lewa me ke ola ʻelemakule i loko o nā plastic.
ʻO ka lubrication kiʻekiʻe ka mea haʻahaʻa haʻahaʻa haʻahaʻa i nā mea paʻa.
ʻO ka non-adhesion ka haʻahaʻa haʻahaʻa haʻahaʻa i nā mea paʻa, ʻaʻole pili i kekahi mea.
ʻAʻohe mea ʻawaʻawa me ka physiological inertia, ʻaʻohe mea ʻawaʻawa i nā mea ola.
ʻO nā noi nui o ka fluorine lined valve:
KUKULU KA VALVE LINED FLUORINE NO ke kinoea kino a me ka wai, ʻaʻole kūpono nā ʻano ʻano ʻano like ʻole o ka paipu kila kila a me ka paipu metala no ka lawe ʻana i ka medium, kila PTFE complex. ʻO ke kila polyvinylidene fluoride composite pipe he kūpono ia no ka lawe ʻana i nā media corrosive me ka mahana hana mai -40 ℃ a + 150 ℃.
ʻO ka hoʻomaka ʻana o ka ʻenehana hana ʻenehana fluorine lining valve
A, tetrafluoroethylene (PTFE)- ke ʻano hoʻopaʻa hoʻopaʻa ʻana i ka solution solution sodium naphthalene
Polytetrafluoroethylene (PTFE) - ka sodium naphthalene solution treatment bonding method: sodium naphthalene solution treatment of fluorine in materials, mostly through corrosion wai a me PTFE plastic chemical reaction, haehae i kekahi hapa o ka fluorine atoms ma ka ili o ka mea, pela ma ka ili hema. he papa kalapona a me kekahi mau pūʻulu polar. Hōʻike ka spectrum infrared i ka hoʻokomo ʻana o ka hui hydroxyl, ka hui carbonyl a me ka paʻa unsaturated a me nā pūʻulu polar ʻē aʻe ma ka ʻili, hiki i kēia mau pūʻulu ke hoʻonui i ka ikehu o ka ʻili, hoʻemi i ka Angle pili, hoʻomaikaʻi i ka wettability, mai ka paʻakikī a paʻa. ʻO kēia ke ala ʻoi loa a hoʻohana mau ʻia ma waena o nā ʻano hana a pau i aʻo ʻia i kēia manawa. Hoʻohana pinepine ʻia ka sodium naphthalene tetrahydrofuran ma ke ʻano he hopena corrosion. Penei ke kaʻina hana hoʻopaʻa.
(1) Hoʻomākaukau i ka hopena lapaʻau: hoʻohui i kahi nui o ka metala sodium i loko o ka hopena o ka tetrahydrofuran a me ka naphthalene, hoʻomalu ʻia ka hapa nui o ka metala sodium ma 3% -5%, hoʻoulu i ka lumi wela no kahi 2h, a hiki i ke kala o ke kala. ʻeleʻele a ʻeleʻele paha ka hopena;
