進口對夾式蝶閥(德國OLES奧萊斯閥門)
【進口對夾式蝶閥】詳細說明:
是指關閉件(閥瓣或蝶板)為圓盤,圍繞閥軸旋轉來達到開啟與關閉的一種閥,在管道上主要起切斷和節(jié)流用。蝶閥啟閉件是一個圓盤形的蝶板,在閥體內繞其自身的軸線旋轉,從而達到啟閉或調節(jié)的目的。蝶閥全開到全關通常是小于90° ,蝶閥和蝶桿本身沒有自鎖能力,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,還能改善閥門的操作性能。工業(yè)蝶閥的特點能耐高溫,適用壓力范圍也較高,閥門公稱通徑大,閥體采用碳鋼制造,閥板的密封圈采用金屬環(huán)代替橡膠環(huán)。大型高溫蝶閥采用鋼板焊接制造,主要用于高溫介質的煙風道和煤氣管道。
It refers to a kind of valve whose closure part (disc or butterfly plate) is a disc and rotates around the valve axis to open and close. It is mainly used for cutting and throttling in the pipeline. The opening and closing part of butterfly valve is a disc-shaped butterfly plate, which rotates around its own axis in the valve body to achieve the purpose of opening and closing or regulating. Butterfly valves are usually less than 90 degrees open to close. Butterfly valves and butterfly rods have no self-locking ability. In order to locate the butterfly plate, worm gear reducer should be installed on the valve stem. The use of worm gear reducer can not only make butterfly plate have self-locking ability, make butterfly plate stop at any position, but also improve the operation performance of the valve. Industrial butterfly valves are characterized by high temperature resistance, high pressure range, large nominal diameter, carbon steel body and metal ring instead of rubber ring. Large high temperature butterfly valve is welded by steel plate, mainly used for flue gas duct and gas pipeline of high temperature medium.

【進口對夾式蝶閥】特性:
對夾式硬密封蝶閥采用的是三維偏心原理設計,使密封面的空間運動軌跡達到理想化,密封面相互之間無磨擦、無干涉、加之密封材料選擇得當,從而使蝶閥的密封性、耐腐蝕性、耐高溫性和耐磨性等得到了可靠的保證。雙德對夾蝶閥結構簡單、體積小、重量輕,只由少數幾個零件組成。而且只需旋轉90°即可快速啟閉,操作簡單,同時該電動閥門具有良好的流體控制特性。蝶閥處于*開啟位置時,蝶板厚度是介質流經閥體時唯1的阻力,因此通過該閥門所產生的壓力降很小,故具有較好的流量控制特性。蝶閥的結構原理尤其適合制作大口徑閥門。由于本產品蝶閥采用的是三維偏心原理設計,使密封面的空間運動軌跡達到理想化,密封面相互之間無磨擦、無干涉、加之密封材料選擇得當,從而使蝶閥的密封性、耐腐蝕性、耐高溫性和耐磨性等得到了可靠的保證。雙德蝶閥不僅在石油、煤氣、化工、水處理等一般工業(yè)上得到廣泛應用,而且還應用于熱電站的冷卻水系統(tǒng)。
