style="text-indent:25px">閥門(mén)的密封性能是指閥門(mén)各密封部位阻止介質(zhì)泄漏的能力，它是閥門(mén)比較重要的技術(shù)性能指標(biāo)。閥門(mén)的密封部位有三處：?jiǎn)㈤]件與閥座兩密封面間的接觸處；填料與閥桿和填料函的配合處；閥體與閥蓋的連接處。其中前一處的泄漏叫做內(nèi)漏，也就是一般所說(shuō)的關(guān)不嚴(yán)，它將影響閥門(mén)截?cái)嘟橘|(zhì)的能力。對(duì)于截?cái)嚅y類(lèi)來(lái)說(shuō)，內(nèi)漏是不允許的。后兩處的泄漏叫做外漏，即介質(zhì)從閥內(nèi)泄漏到閥外。外漏會(huì)造成物料損失，污染環(huán)境，嚴(yán)重時(shí)還會(huì)造成問(wèn)題。對(duì)于易燃易爆、有害或有放射的介質(zhì)，外漏更是不能允許的，所以閥門(mén)需要具有可靠的密封性能。美國(guó)MAC比例閥閥門(mén)的工作原理是什么？</p><div

氣動(dòng)蝶閥是由氣動(dòng)執(zhí)行器和蝶閥主要部件構(gòu)成。氣動(dòng)蝶閥是通過(guò)隨閥干轉(zhuǎn)動(dòng)的圓形蝶板動(dòng)作實(shí)現(xiàn)啟閉的,目前蝶閥在低壓大中口徑管道上的使用越來(lái)越多。蝶閥的蝶板安裝于管道的直徑方向。在蝶閥閥體中蝶板繞著閥門(mén)中軸線(xiàn)旋轉(zhuǎn)，旋轉(zhuǎn)到90°時(shí)，閥門(mén)則處于全開(kāi)狀態(tài)。氣動(dòng)蝶閥擁有結(jié)構(gòu)簡(jiǎn)單、體積小、重量輕，在動(dòng)作時(shí)只需旋轉(zhuǎn)90°即可快速啟閉，操作十分簡(jiǎn)單，同時(shí)該閥門(mén)具有良好的流體介質(zhì)控制性。基本無(wú)流阻，閥門(mén)處于完全開(kāi)啟位置時(shí)，蝶板的厚度便是介質(zhì)流經(jīng)閥體時(shí)阻力，因此通過(guò)該閥門(mén)所產(chǎn)生的壓力降很小，也就是為什么有較好的流量控制特性了。其有金屬密封和軟性密封兩種形式，其中采用金屬密封的閥門(mén)一般比彈性密封的閥門(mén)壽命長(zhǎng)，但缺點(diǎn)是不能做到完全的密封，不過(guò)金屬密封能適應(yīng)較高的工作溫度環(huán)境下，軟性密封則具有受溫度的局限。 </p> <p> <br /> </p> <p> <br /> </p> <p> <br /> </p><p style="text-indent:25px">在眾多的閥門(mén)產(chǎn)品中，閘閥和蝶閥都是很是常用的閥門(mén)型號(hào)。然而，很多用戶(hù)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(mén)。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(chēng)為閘板或閘門(mén)，閘座稱(chēng)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(mén)座通道中心線(xiàn)的片面作為升降運(yùn)動(dòng)，像閘門(mén)一樣截?cái)喙苈分械慕橘|(zhì)，故稱(chēng)做閘閥。而蝶閥是指關(guān)閉件(閥瓣或蝶板)為圓盤(pán)，圍繞閥軸旋轉(zhuǎn)來(lái)達(dá)到開(kāi)啟與關(guān)閉的一種閥，在管道上主要起切斷和節(jié)流用。蝶閥啟閉件是一個(gè)圓盤(pán)形的蝶板，在閥體內(nèi)繞其自身的軸線(xiàn)旋轉(zhuǎn)，從而達(dá)到啟閉或調(diào)節(jié)的目的。蝶閥全開(kāi)到全關(guān)通常是小于90°，蝶閥和蝶桿本身沒(méi)有自鎖能力，為了蝶板的定位，要在閥桿上加裝蝸輪減速器。采用蝸輪減速器，不僅可以使蝶板具有自鎖能力，使蝶板停止在任意位置上，還能改善閥門(mén)的操作性能。閥門(mén)的維護(hù)方面我們應(yīng)該注意什么？</p><div

style="text-indent:25px">球閥按結(jié)構(gòu)形式可分為浮動(dòng)球球閥、固定球球閥、彈性球球閥； ①浮動(dòng)球球閥：球閥的球體是浮動(dòng)的，在介質(zhì)壓力作用下，球體能產(chǎn)生一定的位移并緊壓在出口端的密封面上，保證出口端密封。浮動(dòng)球球閥的結(jié)構(gòu)簡(jiǎn)單，密封性好，但球體承受工作介質(zhì)的載荷全部傳給了出口密封圈，因此要考慮密封圈材料能否經(jīng)受得住球體介質(zhì)的工作載荷。這種結(jié)構(gòu)，大范圍用于中低壓球閥。 ②固定球球閥:球閥的球體是固定的，受壓后不產(chǎn)生移動(dòng)。固定球球閥都帶有浮動(dòng)閥座，受介質(zhì)壓力后，閥座產(chǎn)生移動(dòng)，使密封圈緊壓在球體上，以保證密封。通常在與球體的上、下軸上裝有軸承，操作扭距小，適用于高壓和大口徑的閥門(mén)。為了減少球閥的操作扭矩和增加密封的可靠程度，出現(xiàn)了油封球閥，密封面間壓注特制的潤(rùn)滑油，以形成一層油膜，即增強(qiáng)了密封性，又減少了操作扭矩，更適用高壓大口徑的球閥。 ③彈性球球閥:球體和閥座密封圈都采用金屬材料制造，密封比壓很大，依靠介質(zhì)本身的壓力已達(dá)不到密封的要求，必須施加外力。這種閥門(mén)適用于高溫高壓介質(zhì)。彈性球體是在球體內(nèi)壁的下端開(kāi)一條彈性槽，而獲得彈性。當(dāng)關(guān)閉通道時(shí)，用閥桿的楔形頭使球體漲開(kāi)與閥座壓緊達(dá)到密封。美國(guó)VICKERS減壓閥</p><p
