style="text-indent:25px">蝶閥又叫翻板閥，常用于發(fā)生爐、煤氣、天然氣、液化石油氣、冷熱空氣、化工冶煉等工程系統(tǒng)中輸送各種腐蝕性、非腐蝕性流體介質(zhì)的管道上，用于調(diào)節(jié)和截?cái)嘟橘|(zhì)的流動(dòng)。蝶閥又分為同心蝶閥、單偏心蝶閥、雙偏心蝶閥、三偏心蝶閥； ①同心蝶閥：該種蝶閥的結(jié)構(gòu)特征為閥桿軸心、蝶板中心、本體中心在同一位置上。結(jié)構(gòu)簡(jiǎn)單、制造方便。常見(jiàn)的襯膠蝶閥即屬于此類。 ②單偏心蝶閥：為解決同心蝶閥的蝶板與閥座的擠壓?jiǎn)栴}，由此產(chǎn)生了單偏心蝶閥。其結(jié)構(gòu)特征為閥桿軸心偏離了蝶板中心，從而使蝶板上下端不再成為回轉(zhuǎn)軸心，分散、減輕了蝶板上下端與閥座的過(guò)度擠壓。 ③雙偏心蝶閥：其結(jié)構(gòu)特征為在閥桿軸心既偏離蝶板中心，也偏離本體中心。雙偏心的效果使閥門被開(kāi)啟后蝶板能迅即脫離閥座，大幅度地解決了蝶板與閥座的不必要的過(guò)度擠壓、刮擦現(xiàn)象，減輕了開(kāi)啟阻距，降低了磨損，意大利迪普馬比例閥，提高了閥座壽命 ④三偏心蝶閥：其結(jié)構(gòu)特征為在雙偏心的閥桿軸心位置偏心的同時(shí)，意大利迪普馬比例閥，意大利迪普馬比例閥，使蝶板密封面的圓錐型軸線偏斜于本體圓柱軸線。第三次偏心的特點(diǎn)就是從根本上改變了密封構(gòu)造，一舉解決了金屬閥座零泄漏這一難題，并因接觸面壓與介質(zhì)壓力是成正比的，耐高壓高溫也迎刃而解。購(gòu)買閥門我們應(yīng)該注意什么？意大利迪普馬比例閥</p><div

style="text-indent:25px">分溢流閥、減壓閥、順序閥這三種閥都是壓力控制閥，他們的工作原理基本相同，都是以壓力油的控制壓力來(lái)使閥口啟閉。不同點(diǎn)的是減壓閥主要是用來(lái)降低液壓系統(tǒng)某一分支油路的壓力，使分支壓力比主油路壓力低且穩(wěn)定，在調(diào)定壓力的范圍內(nèi)，減壓閥也像溢流閥那樣是關(guān)閉的。但是隨著系統(tǒng)壓力的升高當(dāng)達(dá)到減壓閥調(diào)定的壓力時(shí)，減壓閥打開(kāi)，部分油液會(huì)經(jīng)過(guò)他返回油箱（此時(shí)有一定壓力的油回油箱，油箱的油溫會(huì)上升），這一支路的油壓是不會(huì)上升了。減壓閥起到對(duì)本支路的減壓與穩(wěn)壓作用。溢流閥則不同，它裝在泵的出口處會(huì)保證系統(tǒng)的整體壓力穩(wěn)定且不會(huì)超壓。可以說(shuō)溢流閥是被動(dòng)工作，而減壓閥是主動(dòng)工作。</p><p

不銹鋼閘閥的啟閉件是閘板，該閘板的運(yùn)動(dòng)方向與流體方向是相互垂直的。不銹鋼閘閥的閘板隨閥桿一起作直線運(yùn)動(dòng)的，叫升降桿不銹鋼閘閥(亦叫明桿不銹鋼閘閥)。一般在升降桿上會(huì)有梯形螺紋，通過(guò)閥門頂端的螺母以及閥體上的導(dǎo)槽，將旋轉(zhuǎn)運(yùn)動(dòng)變?yōu)橹本€運(yùn)動(dòng),也就是將操作轉(zhuǎn)矩變?yōu)椴僮魍屏?。不銹鋼閘閥的密封面可以只依靠介質(zhì)壓力來(lái)密封,即依靠介質(zhì)壓力將閘板的密封面壓向另一側(cè)的閥座來(lái)保證密封面的密封，這就是自密封。大部分不銹鋼閘閥是采用強(qiáng)制密封的,即閥門關(guān)閉時(shí)，要依靠外力強(qiáng)行將閘板壓向閥座, 以保證密封面的密封性。另外不銹鋼閘閥只能起到全開(kāi)和全關(guān)的作用, 不能作為調(diào)節(jié)和節(jié)流的功能。 </p> <p> <br /> </p> <p> <br /> 意大利迪普馬比例閥</p><p
