一、进口两位三通电磁阀产品概述：

德国《LOCKE》洛克--进口二位三通电磁阀为双线圈控制，一个线圈瞬间通电后关闭电源、阀打开，另一个线圈瞬间通电后关闭电源、阀关闭。可以长时间保持关闭或打开状态，能使线圈寿命更长。在高温管道中使用较佳。应用范围燃气燃油、环保设备、加湿设备、暖通空调、水处理、锅炉、包装机械、纺织印染、清洗设备、园林喷灌、啤酒饮料、食品加工等控制系统。

1、 Introduction of imported two position three way solenoid valve products:

German "Locke" - imported two position three-way solenoid valve is controlled by two coils. One coil turns off the power supply and opens the valve after instant power on, and the other coil turns off the power supply and closes the valve after instant power on. It can be kept closed or open for a long time, which can make the coil life longer. It is better to use in high temperature pipeline. Application scope: gas and oil, environmental protection equipment, humidification equipment, HVAC, water treatment, boiler, packaging machinery, textile printing and dyeing, cleaning equipment, garden sprinkler, beer and beverage, food processing and other control systems.

三、进口两位三通电磁阀工作原理：

一进一出：常闭式：当线圈通电时，2通向1,1与3关闭。当线圈断电，2与1关闭，1通向3.

常开式：当线圈通电时，3与1关闭，1通向2.当线圈断电时，3通向1,1与2关闭。

一进二出：当线圈通电时，1通向2,1与3关闭。当线圈断电时，1与2关闭，1通向3.

二进一出：当线圈通电时，2通向1,3与1关闭。当线圈断电时，2与1关闭，3通向1.

注：二进一出的工作原理的电磁阀两进口端压力不相等时，需加止回阀。

3、 Working principle of imported two position three way solenoid valve:

One in one out: normally closed: when the coil is energized, 2 leads to 1, 1 and 3 close. When the coil is de energized, 2 and 1 close and 1 leads to 3

Normally open: when the coil is powered on, 3 and 1 are closed, 1 leads to 2. When the coil is powered off, 3 leads to 1, 1 and 2 are closed.

One in two out: when the coil is energized, 1 leads to 2, 1 and 3 close. When the coil is de energized, 1 and 2 are closed and 1 leads to 3

Two in and one out: when the coil is energized, 2 leads to 1, 3 and 1 is closed. When the coil is de energized, 2 and 1 are closed and 3 leads to 1

Note: when the pressure at the two inlet ends of the solenoid valve with the working principle of two in and one out is not equal, a check valve shall be added.

四、进口两位三通电磁阀性能特点：

1、电磁阀内部组件均为不锈钢制造，采用数控加工中心制成，控制尺寸精度高，产品互换性好。

2、活塞环采用耐磨特殊材料，伸展自如，不会被介质中的杂质卡死，具有自动间隙补偿功能，动密封性能高。

3、金属活塞与金属阀腔不产生直接摩擦，活塞寿命增长，可连续动作百万次以上。

4、阀体的安装方位不受限制，垂直、水平、倾斜都可以。

5、特制线圈，线圈不易烧毁。合理的密封结构，密封性能更好。

6、长期停止动作后的重新启动，动作同样灵敏。

4、 Performance characteristics of imported two position three way solenoid valve:

1. The internal components of the solenoid valve are all made of stainless steel and made of CNC machining center, with high precision and good interchangeability.

2. The piston ring is made of special wear-resistant material, which can stretch freely and will not be stuck by impurities in the medium. It has automatic clearance compensation function and high dynamic sealing performance.

3. There is no direct friction between the metal piston and the metal valve cavity, the service life of the piston increases, and the piston can move continuously for more than one million times.

4. The installation position of the valve body is not limited, vertical, horizontal and inclined.

5. Autocratic coil, coil is not easy to burn. Reasonable sealing structure, better sealing performance.

6. After a long-term stop action, restart, action is also sensitive.
