閥門型號(hào)通常應(yīng)表示出閥門類型、驅(qū)動(dòng)方式、連接形式、結(jié)構(gòu)特點(diǎn)、密封面材料、閥體材料和公稱壓力等元素。閥門型號(hào)的標(biāo)準(zhǔn)化對(duì)閥門的設(shè)計(jì)、選用、銷售提供了方便。當(dāng)今閥門的類型和材料越來(lái)越多，閥門的型號(hào)編制也愈來(lái)愈復(fù)雜。中國(guó)雖有閥門型號(hào)編制的統(tǒng)一標(biāo)準(zhǔn)，德國(guó)費(fèi)斯托單向節(jié)流閥，但愈來(lái)愈不能適應(yīng)閥門工業(yè)發(fā)展的需要，德國(guó)費(fèi)斯托單向節(jié)流閥。目前，德國(guó)費(fèi)斯托單向節(jié)流閥，國(guó)內(nèi)閥門制造廠通常采用JB/T

style="text-indent:25px">在眾多的閥門產(chǎn)品中，閘閥和蝶閥都是很是常用的閥門型號(hào)。然而，很多用戶在選型時(shí)因不知道閘閥和蝶閥的區(qū)別是什么，而不知道如何選擇這兩種閥門。其實(shí)吧，從定義上區(qū)分；閘閥是一種較為常見(jiàn)的啟閉閥，利用閘板(即啟閉件，在閘板中啟閉件稱為閘板或閘門，閘座稱為閘板座)來(lái)接通(全開(kāi))或截?cái)?全關(guān))管路中的介質(zhì)。它不允許作為截流用，使用中應(yīng)避免將閘板微量開(kāi)啟，因高速流動(dòng)的介質(zhì)的沖蝕會(huì)加速密封面的損壞。閘板在垂直于閘門座通道中心線的片面作為升降運(yùn)動(dòng)，像閘門一樣截?cái)喙苈分械慕橘|(zhì)，故稱做閘閥。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)。蝶閥是用圓形蝶板作啟閉件并隨閥桿轉(zhuǎn)動(dòng)來(lái)開(kāi)啟、關(guān)閉和調(diào)節(jié)流體通道的一種閥門。蝶閥的蝶板安裝于管道的直徑方向。在蝶閥閥體圓柱形通道內(nèi)，圓盤形蝶板繞著軸線旋轉(zhuǎn)，旋轉(zhuǎn)角度為0°~90°之間，旋轉(zhuǎn)到90°時(shí)，閥門則程全開(kāi)狀態(tài)。改變碟板的偏轉(zhuǎn)角度，即可控制介質(zhì)的流量。德國(guó)費(fèi)斯托單向節(jié)流閥閥門的型號(hào)那么多，該如何選擇？</p><div

style="text-indent:25px">水閥是一種閥門也稱疏水器，排水閥是將蒸汽系統(tǒng)中的凝結(jié)水、空氣和二氧化碳?xì)怏w盡**出，同時(shí)大限度地自動(dòng)防止蒸汽的泄漏。疏水閥的品種很多，各有不同的性能。選用疏水閥時(shí)，首先應(yīng)選其特性能滿足蒸汽加熱設(shè)備的運(yùn)行，然后才考慮其他客觀條件，這樣選擇你所需要的疏水閥才是正確和有效的。像自由浮球式蒸汽疏水閥就是利用浮力原理，浮球根據(jù)凝結(jié)水量的多少，隨水位的變化而作升降，自動(dòng)調(diào)節(jié)閥座孔的開(kāi)度，連續(xù)排放凝結(jié)水，當(dāng)凝結(jié)水停止進(jìn)入時(shí)，浮球降的底部，回到關(guān)閉位置，排水停止，由于排水閥座孔總是在凝結(jié)水位以下，形成水封、水、氣自然分離，達(dá)到無(wú)蒸汽泄漏。</p><p 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，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)，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。閥門的安裝應(yīng)該注意什么？</p><div

style="text-indent:25px">截止閥又稱截門閥，屬于強(qiáng)制密封式閥門，所以在閥門關(guān)閉時(shí)，必須向閥瓣施加壓力，以強(qiáng)制密封面不泄漏。當(dāng)介質(zhì)由閥瓣下方進(jìn)入閥門時(shí)，操作力所需要克服的阻力，是閥桿和填料的摩擦力與由介質(zhì)的壓力所產(chǎn)生的推力，關(guān)閥門的力比開(kāi)閥門的力大，所以閥桿的直徑要大，否則會(huì)發(fā)生閥桿頂彎的故障。截止閥的啟閉件是塞形的閥瓣，密封面呈平面或錐面，閥瓣沿流體的中心線作直線運(yùn)動(dòng)。閥桿的運(yùn)動(dòng)形式，有升降桿式（閥桿升降，手輪不升降），也有升降旋轉(zhuǎn)桿式（手輪與閥桿一起旋轉(zhuǎn)升降，螺母設(shè)在閥體上）。截止閥的作用只適用于全開(kāi)和全關(guān)，不允許作調(diào)節(jié)和節(jié)流。閥門的使用應(yīng)該注意什么？德國(guó)費(fèi)斯托單向節(jié)流閥</p><p
