进口对夹式蝶阀(德国OLES奥莱斯阀门)
【进口对夹式蝶阀】详细说明:
是指关闭件(阀瓣或蝶板)为圆盘,围绕阀轴旋转来达到开启与关闭的一种阀,在管道上主要起切断和节流用。蝶阀启闭件是一个圆盘形的蝶板,在阀体内绕其自身的轴线旋转,从而达到启闭或调节的目的。蝶阀全开到全关通常是小于90° ,蝶阀和蝶杆本身没有自锁能力,为了蝶板的定位,要在阀杆上加装蜗轮减速器。采用蜗轮减速器,不仅可以使蝶板具有自锁能力,使蝶板停止在任意位置上,还能改善阀门的操作性能。工业蝶阀的特点能耐高温,适用压力范围也较高,阀门公称通径大,阀体采用碳钢制造,阀板的密封圈采用金属环代替橡胶环。大型高温蝶阀采用钢板焊接制造,主要用于高温介质的烟风道和煤气管道。
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.

【进口对夹式蝶阀】特性:
对夹式硬密封蝶阀采用的是三维偏心原理设计,使密封面的空间运动轨迹达到理想化,密封面相互之间无磨擦、无干涉、加之密封材料选择得当,从而使蝶阀的密封性、耐腐蚀性、耐高温性和耐磨性等得到了可靠的保证。双德对夹蝶阀结构简单、体积小、重量轻,只由少数几个零件组成。而且只需旋转90°即可快速启闭,操作简单,同时该电动阀门具有良好的流体控制特性。蝶阀处于*开启位置时,蝶板厚度是介质流经阀体时唯1的阻力,因此通过该阀门所产生的压力降很小,故具有较好的流量控制特性。蝶阀的结构原理尤其适合制作大口径阀门。由于本产品蝶阀采用的是三维偏心原理设计,使密封面的空间运动轨迹达到理想化,密封面相互之间无磨擦、无干涉、加之密封材料选择得当,从而使蝶阀的密封性、耐腐蚀性、耐高温性和耐磨性等得到了可靠的保证。双德蝶阀不仅在石油、煤气、化工、水处理等一般工业上得到广泛应用,而且还应用于热电站的冷却水系统。
