代理德国哈威换向阀,哈威换向阀全系列*
德国哈威HAWE换向阀又称克里斯阀,阀门的一种,具有多向可调的通道,可适时改变流体流向。
工作时借着阀外的驱动传动机构转动驱动轴,带动摇拐臂,启动阀板,使工作流体时而从左入口通向阀的下部出口,时而从右入口变换通向下部出口,实现了周期变换流向的目的。

德国哈威HAWE换向阀主要由阀体、密封组件、凸轮、阀杆、手柄和阀盖等零部件组成(图1)。阀门由手柄驱动,通过手柄带动阀杆与凸轮旋转,凸轮具有定位驱动与锁定密封组件的开启与关闭功能。手柄逆时针旋转,两组密封组件分别在凸轮的作用下关闭下端的两个通道,上端的两个通道分别与管道装置的进口相通。反之,上端的两个通道关闭,下端两个通道与管道装置的进口相通,实现了不停车换向。 换向阀是具有两种以上流动形式和两个以上油口的方向控制阀。是实现液压油流的沟通、切断和换向,以及压力卸载和顺序动作控制的阀门。可分为手动换向阀、电磁换向阀、电液换向阀等。
这种变换阀在石油、化工生产中有着广泛的应用,在合成氨造气系统中zui为常用。此外,换向阀还可作成阀瓣式的结构,多用于较小流量的场合。工作时只需转动手轮通过阀瓣来变换工作流体的流向。
BEM - 截止阀
These 2/2-way ball seated directional valves are either directly or pilot actuated by a solenoid. With the directly actuated version the valve passage is opened or closed by a cone whereas with the piloted a piloting duct of a stepped piston is opened or closed generating a pressure difference at the opposing facial areas of the piston forcing it in the open or closed position. Type EMP is a proportional valve, acting like a throttle but with zero leakage in blocked position. The dampened version will increase the switching time for on/off controls (hydraulic ramp). The wet armature solenoids for the valve actuation are pressure resistant, where all moving internal parts are flushed by oil. There is a wide range of connection blocks either for pipe connection or for banjo bolt mounting, which may feature optional elements such as drain valve, by-pass throttle, pressure switch, 2-way flow control valve etc.
