Cov kab xev tsis yog hlau
Nws feem ntau siv cov ntaub ntawv uas tsis yog xim hlau yog, xws li hloov tau graphite (<600 ° C), polytetrafluoroethylene (-200 ~ 260 ° C), fiber ntau reinforced roj hmab raws li kev sib xyaw board.
Ribbon ntawm Hlau
StrapsShape: V, W, wavy, thiab lwm yam Khoom siv: 0.15 ~ 0.25 tsawg carbon steel, stainless hlau, tooj liab thiab lwm yam corrosion resistant alloys, etc.Function: tswj lub compression resilience ntawm lub gasket, sealing;Ua kom lub zuag qhia tag nrho ntawm lub gasket.
Lub nplhaib puab
Lub hauv paus ntsiab lus: Lub nplhaib puab yog nyob rau hauv kev sib cuag nrog cov kua, thiab nws cov khoom yuav tsum tau resistant rau corrosion ntawm lub sealing nruab nrab.
Khoom siv: carbon hlau, stainless hlau, lwm yam corrosion resistant alloys, thiab lwm yam.
Kev Ua Haujlwm: Txhawm rau tiv thaiv qhov sib txawv ntawm qhov sib khi thiab lub thawv lossis cov yeeb nkab flange kom tsis txhob muaj qhov sib txawv no cuam tshuam cov dej ntws thiab cov kua dej yaig ntawm lub gasket.Thaum cov kua dej sab hauv siab thiab kub siab, cov kua dej sab hauv corrosion thiab abrasion yog nruj, cov kua dej tiv thaiv kom tsis txhob muaj qhov sib txawv ntawm flange, gasket loj los yog siv cov convex thiab concave flange thiab lwm zaus, lub nplhaib puab. yog teem.
Nrhiav lub nplhaib (sab nraud)
Muaj nuj nqi: txhawb thiab kho qhov chaw ntawm lub gasket lub cev, tiv thaiv kev nruj compression los ntawm kev poob lub springback lub peev xwm ntawm lub gasket thiab tiv thaiv lub gasket los ntawm xoob. Khoom siv: Lub nplhaib reinforcing los yog lub nplhaib sab nrauv yog cov khoom hlau, (xws li carbon steel, stainless hlau, lwm yam corrosion resistant alloys) lub nplhaib sab nraud yog tsis nyob rau hauv kev sib cuag nrog lub sealing nruab nrab, yog li nws tsis tas yuav tiv taus nruab nrab corrosion, yog li nws feem ntau yog ua los ntawm cov khoom siv carbon steel.Lub nplhaib sab nrauv tuaj yeem ua tau. yuav ua rau tag nrho nrog sealing ntsiab, xws li hlau toothed gasket thiab yoj toothed composite gasket.
2, polytetrafluoroethylene gasket
Nyob rau hauv kev siv tau ntawm qhov kub thiab txias (-180 - 250 ℃) tsis tuaj yeem corroded los ntawm cov tshuaj thiab cov kuab tshuaj, tab sis kuj tuaj yeem ua los tiv thaiv electrochemical corrosion yeeb nkab rwb thaiv tsev gasket.Classification (1) Polytetrafluoroethylene ca gasket: feem ntau haum rau convex thiab concave. flange thiab flange nrog cov kab dej, tsis yog rau flange dav.Feem ntau siv rau kev tiv thaiv corrosion.Yuav kom ua tiav cov nyhuv sealing zoo, lub gasket tuaj yeem coated nrog teflon muab tshuaj txhuam.Tab sis qhov to, compression tsis kam tshaj PTFE ca gasket yog superior, yuav siv tau rau dav flange.Qhov tsawg kawg nkaus preload tshwj xeeb siab y ntawm lub foob yog 11.77-19.6MPa, siv kub yog 200 ℃, siab yog hais txog 0.98MPa .
