德国奥莱斯OLES进口电动硬密封蝶阀
【进口电动硬密封蝶阀】详细说明:
本阀从设计思路上改变了传统的靠机械变速来完成蝶板开关速度变化的模式,根据蝶板不同位置的动作特点,从电动驱动控制上进行了全新的设计。电动法兰蝶阀采取改电动装置输入电流的频率,进而调整电动装置的转动速度和输出力矩,以达到控制蝶板开工关速度,实现蝶板快关、慢关两阶段关闭或慢开、快开两阶段开启的目的。与液控蝶阀具有同样的功能。本阀适用于介质为水、海水的管路的 泵出口位置,作为闭路阀兼有止回阀的特性,用以避免和减少管路系统中介质的倒流和水锤冲击,保护管路.对于电厂、水厂等工作电源十分可靠的场合尤其适用。
This valve has changed the traditional mode of changing the speed of butterfly plate switch by mechanical speed change from the design idea. According to the action characteristics of different positions of butterfly plate, a new design has been carried out from the electric drive control. The electric flange butterfly valve adopts changing the frequency of input current of the electric device, and then adjusts the rotating speed and output torque of the electric device so as to control the speed of starting and closing of the butterfly plate and realize the purpose of closing the butterfly plate in two stages of fast closing and slow closing, or opening in two stages of slow opening and fast opening. It has the same function as the hydraulic butterfly valve. This valve is suitable for outlet position of pump in pipeline with medium of water and sea water. It has the characteristics of both closed-circuit valve and check valve. It can avoid and reduce backflow of medium in pipeline system and water hammer impact, and protect pipeline. It is especially suitable for power plants and water plants where working power supply is very reliable.
【进口电动硬密封蝶阀】特点:
【进口电动硬密封蝶阀】工作原理:
1)偏离管道正中
2)偏离密封面正中
3)倾斜的锥形
当阀门开启时,蝶板与阀座在关闭时就接触,利用蝶板偏心1、偏心2迅速脱离阀座,降低了密封副的磨损,磨擦力矩小,开启灵活。偏心锥面3,使阀门在开启或关闭时蝶板能通过阀座内孔,实现接触密封。另外,锥形蝶板的旋转半径大于密封副接触位置的旋转半径,故蝶板在阀门关闭时将出现越关越紧,能够实现自锁,防止蝶板过位。
