品牌：RETZ瑞茨/我们一直致力于流体控制领域的持续创新，始于2005……进口带手动控制电磁阀的性能特点与其他电磁阀性能一样，手柄开关可以在电磁阀线圈无电或烧坏时,实现手动打开或关闭电磁阀，主要用于消防系统安全防护，在各种常温、中温、常压、中压等场合的纯净气体、液体、瓦斯、油品、蒸汽、热水的管路自动控制The performance characteristics of RETZ with manual control solenoid valve are the same as those of other solenoid valves. The handle switch can manually open or close the solenoid valve when the solenoid valve coil is dead or burnt out. It is mainly used for fire protection system safety protection and automatic control of pure gas, liquid, gas, oil, steam, hot water pipelines in various normal temperature, medium temperature, atmospheric pressure, medium pressure and other occasions

进口带手动控制电磁阀工作原理--Working principle of imported manual control solenoid valve

当自动控制时When under automatic control

常闭式-手动开关指向关：线圈通电，电磁阀打开；线圈断电，电磁阀关闭 Normally closed - manual switch pointing to close: the coil is energized and the solenoid valve is opened; Coil power off, solenoid valve closed

常开式-手动开关向开的方向旋转2~4圈，电磁阀不通电为打开状态。当线圈通电时，阀关闭 Normally open - Rotate the manual switch in the open direction for 2-4 turns, and the solenoid valve is in the open state when it is not energized. When the coil is energized, the valve closes

当手动控制时 When manually controlled

旋转手动开关，常闭式手动开关指向开的方向（常开式向开的方向旋转2~4圈）电磁阀打开，介质流通；旋转手动开关，常闭式手动开关指向关的方向（常开式向关的方向旋转到不动为止）电磁阀关闭，介质截止。

Rotate the manual switch, the normally closed manual switch points towards the open direction (the normally open switch rotates 2-4 turns towards the open direction), and the solenoid valve opens, allowing the medium to flow; Rotate the manual switch, with the normally closed manual switch pointing towards the closed direction (the normally open switch rotates towards the closed direction until it remains stationary). The solenoid valve is closed and the medium is cut off.
