进口气体电磁阀 德国洛克气体电磁阀

一、进口气体电磁阀产品概述：

德国《LOCKE》洛克--进口气体电磁阀(Gas solenoid valve )是用电磁控制的工业设备，用在工业控制系流中调整介质的方向，流量，速度和其它的参数。电磁阀是用电磁阀的效应进行控制，主要的控制方式由继电器控制。这样电磁阀可以配合不同电路来实现预期的控制，而控制的精度和灵活性都能够保证。电磁阀有很多种，不同的电磁阀在控制系统的不同位置发挥作 用，较常用的是单向阀，安全阀，方向控制阀，速度调节阀等等。 

1、 Overview of imported gas solenoid valve products:

German "LOCKE" Rock -- Gas solenoid valve (imported solenoid valve) is an electromagnetic controlled industrial equipment, which is used to adjust the direction, flow, speed and other parameters of the medium in the industrial control system. Solenoid valve is controlled by the effect of solenoid valve, and the main control mode is controlled by relay. In this way, the solenoid valve can cooperate with different circuits to achieve the desired control, and the control accuracy and flexibility can be guaranteed. There are many kinds of solenoid valves, different solenoid valves play a role in different positions of the control system, the more commonly used are one-way valve, safety valve, direction control valve, speed control valve and so on.

三、进口气体电磁阀工作原理：

常闭：当线圈通电时，先导阀芯吸合，先导孔打开，阀上腔卸压，活塞靠下腔介质压力推动，电磁阀打开。

当线圈断电时，先导阀芯靠弹簧复位，先导孔关闭，阀上腔由活塞节流孔增压和复位弹簧的推力，电磁阀关闭。

常开：当线圈通电时，先导阀芯靠弹簧复位，先导孔关闭，阀上腔由活塞节流孔增压和复位弹簧的推力，电磁阀关闭。

当线圈断电时，先导阀芯靠弹簧复位，先导孔打开，阀上腔卸压，活塞靠下腔介质压力推动，电磁阀打开。

3、 Working principle of inlet gas solenoid valve:

Normally closed: when the coil is energized, the pilot valve core is closed, the pilot hole is opened, the pressure in the upper chamber of the valve is relieved, the piston is pushed by the medium pressure in the lower chamber, and the solenoid valve is opened.

When the coil is powered off, the pilot valve core is reset by the spring, the pilot hole is closed, the upper chamber of the valve is pressurized by the piston orifice and the thrust of the reset spring, and the solenoid valve is closed.

Normally open: when the coil is energized, the pilot valve core is reset by the spring, the pilot hole is closed, the upper chamber of the valve is pressurized by the piston orifice and the thrust of the reset spring, and the solenoid valve is closed.

When the coil is powered off, the pilot valve core is reset by the spring, the pilot hole is opened, the pressure in the upper chamber of the valve is relieved, the piston is pushed by the medium pressure in the lower chamber, and the solenoid valve is opened.

四、进口气体电磁阀产品特点：

4、 Features of imported gas solenoid valve:

The imported gas solenoid valve can also open the main valve with zero pressure, low pressure difference, large flow and wide application range. The valve core seal can automatically compensate, improve the service life and reliability of the valve, and can be continuously electrified for a long time in special occasions.
