产品描述 Product Description

参照各系列电磁阀中的特点应用，手动柄开关可以在电磁阀线圈无电或烧毁时，实现电磁阀打开和关闭，也可以实现调节流量的功能

Referring to the characteristics and applications of various series of solenoid valves, the manual handle switch can achieve the opening and closing of the solenoid valve when the solenoid valve coil is dead or burned out, and can also achieve the function of regulating flow

常闭型：当电磁阀线圈不通电或烧坏，手动可以打开阀门。但手动处于打开状态时阀不能自动控制。

Normally closed type: When the solenoid valve coil is not energized or burnt out, the valve can be manually opened. But when manually opened, the valve cannot be automatically controlled

常开型：当电磁阀线圈不通电或烧坏，手动可以关闭阀门。但手动处于关闭状态时阀不能自动控制及线圈通电和断电阀都不能打开。

Normally open type: When the solenoid valve coil is not energized or burnt out, the valve can be manually closed. But when manually in the closed state, the valve cannot be automatically controlled, and neither the coil is energized nor the power off valve can be opened

工作原理 working principle

当自动控制时：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。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。

When under automatic control: normally closed - manual switch pointing to closed: coil energized, solenoid valve opened; The coil is de-energized and the solenoid valve is closed. 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：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。

When manually controlled: rotate the manual switch, and the normally closed manual switch points towards the open direction (the normally open switch rotates 2-4 turns towards the open direction). The solenoid valve opens and the medium flows; 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.
