ʻIke kumu o nā gaskets maʻamau

Lipine metala ʻole

ʻO kāna mau mea metala maʻamau, e like me ka graphite maʻalahi (<600 ° C), polytetrafluoroethylene (-200 ~ 260 ° C), fiber reinforced rubber based composite board.

Lipine Metala

StrapsShape: V, W, wavy, etcMaterial: 0.15 ~ 0.25 haʻahaʻa kalapona kila, kuhiliʻole kila, keleawe a me ka corrosion kū'ē nā alloys, etc.Function: hoʻomalu i ka compression resilience o ka gasket, sila;E hoʻonui i ka ʻoʻoleʻa holoʻokoʻa o ka gasket.

apo i loko

Kumu: Ua pili ka apo i loko me ka wai, a ʻo kāna mea pono e kū i ka corrosion o ka mea hoʻopili.

Nā mea waiwai: carbon steel, stainless steel, corrosion resistant alloys, etc.

Hana: No ka pale ʻana i ke āpau ma waena o ka ʻāpana hoʻopaʻa a me ka ipu a i ʻole ka flange paipu e pale ʻia.Ke kiʻekiʻe ka paʻakikī o ka wai o loko a me ka mahana, ʻoi aku ka ikaika o ka wai o loko a me ka abrasion, pale ʻia ka wai mai ka waiho ʻana i ka flange gap, nui ka nui o ka gasket a i ʻole ka hoʻohana ʻana i ka convex a me ka concave flange a me nā manawa ʻē aʻe, ke apo o loko. ua hoonohoia.

Loaʻa i ke apo (outer apo)

Hana: hoʻoikaika a hoʻonohonoho pololei i ke kino gasket, pale ʻana i ka hoʻopaʻa paʻa ʻana mai ka nalowale ʻana o ka hiki o ka springback o ka gasket a me ka pale ʻana i ka gasket mai ka hemo. ke kila kalapona, ke kila kuhiliʻole, nā'āpana pale'ē aʻe)ʻaʻole i pili ka apo hoʻoikaika i waho me ka mea hoʻopaʻa, no laila,ʻaʻole pono e pale i ka corrosion medium, no laila, hana pinepineʻia me ka mea hao kalapona. Hiki ke apo hoʻoikaika i waho. e hana ʻia i mea holoʻokoʻa me nā mea e hoʻopaʻa ʻia ai, e like me ke kinoea niho metala a me ke kinoea hoʻohuihui niho hawewe.

2, polytetrafluoroethylene gasket

I ka hiki ke hoʻohana i ka wela wela (-180 — 250 ℃) hiki ole ke corroded e kemika a me ka solvents, akā, no hoi hiki ke hana anti-electrochemical corrosion paipu insulation gasket.Classification(1) Polytetrafluoroethylene flat gasket: maʻamau kūpono no ka convex a me ka concave. flange a me flange me ka laina wai, ʻaʻole no ka lau ākea.Hoʻohana hou ʻia no nā manawa kūʻē corrosion.No ka loaʻa ʻana o kahi hopena sila maikaʻi, hiki ke uhi ʻia ke kino me ka paʻi teflon.Akā ʻoi aku ka maikaʻi o ka leakage, ʻoi aku ka maikaʻi ma mua o ka PTFE flat gasket, hiki ke hoʻohana ʻia no ka laula ākea. .

Nā laʻana o nā hōʻailona:

ʻAno Gasket: me ke apo i loko a hoʻonohonoho ʻia e like me ke ʻano apo;ʻO ke apo mea he kila kalapona haʻahaʻa, ʻo ka mea kāʻei metala ʻo OCr18Ni9;Nominal anawaena 150mm;Nominal kaomi 4.OMPa(40bar);Gasket nui maʻamau GB/T4622.2-2003;

Ua hōʻailona ʻia: D 1222-DN150-PN40 GB/T4622.2

Keʻano o ka gasket: keʻano kumu;Gasket mea: metala kāʻei mea 0Cr18Ni9, ʻO ka mea hoʻopiha kāʻei mea he graphite maʻalahi;Nominal anawaena 150mm;Nominal kaomi 4.OMPa(40bar);Gasket nui maʻamau GB/T4622.2-2003;
