①明桿閘閥：閥桿螺母在閥蓋或支架上，開閉閘板時，用旋轉閥桿螺母來實現(xiàn)閥桿的升降。這種結構對閥桿的潤滑有利，開閉程度明顯，因此被大范圍采用。 ②暗桿閘閥：閥桿螺母在閥體內，與介質直接接觸。開閉閘板時，用旋轉閥桿來實現(xiàn)。這種結構的優(yōu)點是：閘閥的高度總保持不變，因此安裝空間小，適用于大口徑或對安裝空間受限制的閘閥。其兩個主要區(qū)別是：暗桿法蘭閘閥的提升螺桿是只旋轉而無上和下移動，外露的只是一根桿，其螺母是固定在閘板上，通過螺桿的旋轉來提升閘板，沒有可見的門架；明桿法蘭閘閥的提升螺桿是外露的，螺母緊貼手輪且是固定的（不旋轉也不軸向移動），通過旋轉螺桿來提升閘板，螺桿與閘板只有相對的旋轉運動而無相對的軸向位移，外觀為有門形支架。暗桿閥門就是看不見絲杠，而明桿的就是能看見絲桿的。說簡單點就是明桿閥門是閥瓣連著閥桿一起做上下運動，方向盤始終在固定點。德國ebro閥門價格</p><div

style="text-indent:25px">三偏心蝶閥顧名思義，三個**的偏移被設計成了閥門。三偏心蝶閥問世已經有50多年了，這50多年也在不斷的發(fā)展，使用蝶閥的應用橫跨了多個行業(yè)。原來蝶閥只用于水介質的截斷和聯(lián)通，三偏心的設計增強蝶閥的功能，已經成為工業(yè)工業(yè)管道設備中，關鍵工藝環(huán)境惡劣的條件下性能***的閥門之一。三偏心蝶閥采用精密機加工的密封面和密封環(huán)形成金屬對金屬密封。即使在高溫高壓以及其他的嚴苛的服務環(huán)境，都可以做到雙向密封零泄漏。低摩擦和流線形的標準標準直角圓錐設計，金屬對金屬能很好的解決熱脹冷縮，是在高溫高壓環(huán)境服務的重要特征。金屬對金屬密封允許應用在有防火要求的油田中。閥座密封面采用在閥門本體上堆焊司太立硬質合金，使用密封面有更長的壽命和更好的耐磨性，即使反復循環(huán)使用。這種密封結構設計減少了和蝶板的摩擦，減少了工作扭矩。特殊的閥座設計使用閥門可以自動調整閥門的密封。浮動的密封環(huán)和一個寬的密封環(huán)支撐墊片，使用密封性和啟閉更加可靠。這種閥座確保閥門有雙向密封特性。閥門的設計的定位銷在蝶板很低的位置，允許在熱膨脹時都有良好的性能，大程度的減小閥桿的擾度。因此，閥門有很長的使用壽命。</p><p style="text-indent:25px">適用于截斷流體，氣動是使用在要求環(huán)境不安全、或者自動化程度較高的位置。蝶閥適用于發(fā)生爐、煤氣、天然氣、液化石油氣、城市煤氣、冷熱空氣、化工冶煉和發(fā)電環(huán)保等工程系統(tǒng)中輸送各種腐蝕性、非腐蝕性流體介質的管道上，用于調節(jié)和截斷介質的流動。大范圍應用在化工、電力、石油、化工、天然、氣煉、造紙、制藥等諸多自動控制的工業(yè)管線上的控制終端，它通過定位器、電磁閥或其他設備控制干燥、潤滑的氣體輸入到氣動裝置的缸體，是氣動裝置按給定要求轉向，實現(xiàn)蝶閥的啟閉和調節(jié)動作：更可采用用智能型定位器與現(xiàn)場總線連接，檢測蝶閥狀態(tài)并提供診斷。</p><div

①同心蝶閥：該種蝶閥的結構特征為閥桿軸心、蝶板中心、本體中心在同一位置上。結構簡單、制造方便。常見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問題，由此產生了單偏心蝶閥。其結構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軸心，分散、減輕了蝶板上下端與閥座的過度擠壓。 ③雙偏心蝶閥：其結構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度擠壓、刮擦現(xiàn)象，減輕了開啟阻距，降低了磨損，提高了閥座壽命 ④三偏心蝶閥：其結構特征為在雙偏心的閥桿軸心位置偏心的同時，使蝶板密封面的圓錐型軸線偏斜于本體圓柱軸線。第三次偏心的特點就是從根本上改變了密封構造，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壓力是成正比的，耐高壓高溫也迎刃而解。博雷電動閥門</p><p style="text-indent:25px">羅托克電動閥門</p><p style="text-indent:25px">球閥按結構形式可分為浮動球球閥、固定球球閥、彈性球球閥； ①浮動球球閥：球閥的球體是浮動的，在介質壓力作用下，球體能產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。浮動球球閥的結構簡單，密封性好，但球體承受工作介質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受得住球體介質的工作載荷。這種結構，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，受壓后不產生移動。固定球球閥都帶有浮動閥座，受介質壓力后，閥座產生移動，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。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滑油，以形成一層油膜，即增強了密封性，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，依靠介質本身的壓力已達不到密封的要求，必須施加外力。這種閥門適用于高溫高壓介質。彈性球體是在球體內壁的下端開一條彈性槽，而獲得彈性。當關閉通道時，用閥桿的楔形頭使球體漲開與閥座壓緊達到密封。羅托克電動閥門</p><p
