A fluoropolymer-valv dyafram ki aliyense yon kowozyon -rezistan fèmen-valv fèmen/regleman ak yon fluoroplastic (tankou PTFE oswa FEP) pawa andedan kò valv la (kanal koule ak sifas sele) ak ekipe ak yon dyafram fluoropolymer. Chanèl koule a louvri oswa fèmen pa ogmante oswa bese oswa peze dyafram la.
Pawa fluoropolymer la ak dyafram fluoropolymer la ansanm izole mwayen ki soti nan substra kò valv la (sitou fè jete oswa asye kabòn), anpeche korozyon. Li gen avantaj tankou "rezistans korozyon fò," "pa gen okenn sele ang ki mouri-," ak "zewo kontaminasyon medya," ki konfòme ak estanda GB/T 12239 ak HG/T 4084. Li se lajman ki itilize nan endistri chimik, métallurgique, ak pharmaceutique pou transmèt medya korozivite tankou asid fò, alkali, ak solvang òganik.

Fliyò-Estrikti valv dyafram ak prensip
Izolasyon dyafram
Yon dyafram mou ki fèt ak kawotchou oswa fluoroplastik (tankou PTFE, FEP) konplètman izole kavite entèn kò valv la soti nan konpozan kondwi yo (tankou tij valv la ak disk valv). Konpozan kondwi yo deplase tij valv la atravè lè konprese, elektrisite, oswa operasyon manyèl, sa ki lakòz dyafram nan monte, tonbe, oswa konpresyon, konsa louvri oswa fèmen chemen an koule ak anpeche kontak ant mwayen an ak pati metal yo.
Pwoteksyon pawa fliyò
Mi enteryè ak chemen koule nan kò valv la aliyen ak fluoroplastik (tankou PTFE, PFA), fòme yon baryè korozyon -rezistan. Kouch pawa fluoroplastik la gen yon epesè inifòm (2-5mm) epi li byen kole ak substra a, reziste ewozyon nan medya ki trè korozivite tankou asid idroklorik, asid silfirik, ak asid nitrique.
