自保持节能电磁阀 自保节能电磁阀由永久磁铁、控制线圈、弹簧、活门组件、阀座等组成。主要创新点在于与现有技术比较:现有极化式电磁阀需设置两个工作气隙才能使衔铁在对应于活门开启或关闭状态的两个位置实现自保持功能;本实用新型结构只需一个工作气隙便可具备上述功能,简化了磁路结构,并且在装配调整中没有“衔铁行程必须大于活门提升高度”的限制,因 Since the maintenance of energy-saving solenoid valve self-protection and energy-saving solenoid valve by the permanent magnet, control coil, spring, valve components, seat and other components. The main innovation point is that compared with the prior art, the existing polarized electromagnetic valve needs to set two working air gaps to enable the armature to realize the self-holding function in two positions corresponding to the open or closed state of the valve. The structure of the utility model only needs A working air gap can be equipped with the above functions, simplifying the magnetic circuit structure, and there is no assembly adjustment “armature trip must be greater than the valve lift height” of the limit, because
