Lub diaphragm valve ntawm aluminium alloy toolbox yog lub ntiaj teb valve uas siv lub diaphragm ua qhov qhib thiab kaw lub ntsiab kom kaw cov ndlwg channel, txiav tawm cov kua dej, thiab cais lub valve lub cev kab noj hniav los ntawm lub valve cover kab noj hniav. Diaphragms feem ntau yog ua los ntawm elastic, corrosion-resistant, thiab impermeable cov ntaub ntawv xws li roj hmab thiab yas. Lub cev valve feem ntau yog ua los ntawm cov yas, fiberglass, ceramic, los yog cov ntaub ntawv hlau. Cov qauv yooj yim, kev sib khi zoo thiab kev ua haujlwm tiv thaiv corrosion, thiab tsis muaj dej tsis kam. Siv rau nruab nrab uas tsis tshua muaj siab, tsis tshua muaj kub, muaj zog corrosiveness, thiab cov khoom raug tshem tawm. Raws li cov qauv tsim, nws tuaj yeem muab faib ua hom ridge, hom txiav, hom rooj vag, thiab lwm yam. Raws li kev tsav tsheb, muaj cov phau ntawv, pneumatic, thiab hluav taws xob. Diaphragm li qub siv cov khoom siv tiv thaiv corrosion-resistant lined valve lub cev thiab corrosion-resistant diaphragms es tsis txhob valve core Cheebtsam, siv lub zog ntawm lub diaphragms rau kev hloov. Lub cev lub cev cov khoom ntawm lub diaphragm valve yog ua los ntawm cam khwb cia hlau, cam khwb cia hlau, los yog cam khwb cia hlau stainless, thiab lined nrog ntau yam corrosion-resistant los yog hnav-resistant cov ntaub ntawv, diaphragm khoom roj hmab, thiab polytetrafluoroethylene. Lub diaphragm hauv ob sab phlu muaj zog corrosion kuj thiab yog tsim rau kev tswj cov corrosive media xws li muaj zog acids thiab alkalis.
Cov yam ntxwv ntawm diaphragm li qub:
(1) tuaj yeem siv rau hauv xov xwm uas muaj cov khib nyiab nyuaj; Vim tias qhov nruab nrab tsuas yog los rau hauv kev sib cuag nrog lub valve lub cev thiab lub diaphragm, tsis tas yuav tsum muaj lub thawv ntim khoom, thiab tsis muaj teeb meem rau lub thawv ntim khoom, uas yuav ua rau corrosion rau lub valve qia.
(2) Tsis tuaj yeem siv rau hauv cov xwm txheej siab.
(3) Tsis tshua muaj dej tsis kam.
(4) Haum rau corrosive, viscous, thiab slurry media.
