三偏心蝶閥的結(jié)構(gòu)優(yōu)化分析：隨著工業(yè)技術(shù)的發(fā)展,普通軟密封蝶閥已滿(mǎn)足不了工業(yè)上的需求,金屬硬密封蝶閥很快被開(kāi)發(fā)出來(lái),而三偏心結(jié)構(gòu)蝶閥是蝶閥發(fā)展、演化過(guò)程中比較高級(jí)的一種,但是目前國(guó)內(nèi)還沒(méi)有對(duì)它作深入的研究,還沒(méi)有形成一個(gè)比較完善的理論分析體系,致使三偏心蝶閥的發(fā)展及應(yīng)用受到一定程度的限制。本文主要分析了三偏心蝶閥的結(jié)構(gòu),給出了三偏心的定義,推導(dǎo)出了蝶板截面的幾何方程及其性質(zhì),結(jié)果表明,沿蝶板厚度的平行截面輪廓線為標(biāo)準(zhǔn)的橢圓形,進(jìn)而推導(dǎo)出了蝶板幾個(gè)主要截面的幾何參數(shù)(長(zhǎng)軸、短軸)與三個(gè)偏心量之間的函數(shù)關(guān)系;考慮到蝶板啟閉過(guò)程中避免與閥體及閥座發(fā)生干涉,結(jié)合蝶板的啟閉扭矩,確立了三偏心蝶閥回轉(zhuǎn)中心的適宜區(qū)域。

一般臺(tái)上式超純水機(jī)產(chǎn)水量在5升~3升/小時(shí)，落地式超純水機(jī)產(chǎn)水量則可達(dá)到每小時(shí)上百升。客戶(hù)選擇實(shí)驗(yàn)室超純水機(jī)的產(chǎn)水量不能按每天制水8小時(shí)計(jì)算（如每天用水量為4升，不能選擇每小時(shí)產(chǎn)水量5升的機(jī)型。），否則會(huì)導(dǎo)致耗材消耗過(guò)快，頻繁更換耗材的煩惱。正常情況下，實(shí)驗(yàn)室超純水機(jī)每天制水2~4小時(shí)，無(wú)論是對(duì)機(jī)器電氣元件（水泵、電磁閥等）的損耗，還是耗材更換都有好處（如每天用水量為4升，選擇每小時(shí)產(chǎn)水量1~2升的機(jī)型為宜。
