三、进口氮气电磁阀工作原理：

常闭：当线圈通电时，电磁铁芯吸合，卸压孔打开，主活塞由介质压力推动，打开主阀口，介质流通。当线圈断电时，主阀口关闭，介质截止。

常开：当线圈通电时，电磁铁芯吸合，卸压孔关闭，主活塞由介质压力推动，关闭主阀口，介质截止。当线圈断电时，主阀口打开，介质流通。

3、 Working principle of inlet nitrogen solenoid valve:

Normally closed: when the coil is energized, the electromagnet core is closed, the pressure relief hole is opened, the main piston is pushed by the medium pressure, the main valve port is opened, and the medium flows. When the coil is powered off, the main valve port is closed and the medium is cut off.

Normally open: when the coil is energized, the electromagnet core is closed, the pressure relief hole is closed, the main piston is pushed by the medium pressure, the main valve port is closed, and the medium is cut off. When the coil is powered off, the main valve port opens and the medium flows.

四、进口氮气电磁阀性能特点：

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、专制线圈，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 nitrogen 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.

Roch-the imported nitrogen solenoid valve is used in the nitrogen pipeline solenoid valve, to power, through the magnet coil was sucked, to Open or close the nitrogen valve. The coil of the nitrogen solenoid valve is made of high temperature resistant material. It can be used in high temperature nitrogen medium pipeline and has long service life. Nitrogen solenoid valve can be used protection level, and can choose explosion-proof coil, can be used in complex nitrogen system environment. 2. Imported Nitrogen solenoid valve technical parameters: DIAMETER RANGE: DN3 ~ DN300 PRESSURE RANGE: 0.1 ~ 300MPa control mode: normally closed, normally open, self-maintaining power supply voltage: DC12 ~ 240V, AC220 ~ 380V valve body material: cast steel, stainless steel 304/316 applicable media: water, gas, oil, corrosive fluid temperature range:-50 ~ (+ 120, + 200, + 250) medium viscosity: less than 50C St (more than when need to be customized) protection performance: dustproof, waterproof, explosion-proof. According to the operating conditions of choice three, imported nitrogen solenoid valve working principle: normally closed: when the coil power, electromagnetic core suction, pressure relief hole open, the main piston pressure driven by the medium, open the main valve port, medium flow. When the coil power off, the main valve port closed, the media cut-off. Normally Open: When the coil is energized, the electromagnetic core is absorbed, the pressure relief hole is closed, the main piston is driven by the medium pressure, the main valve port is closed, the medium is cut off. When the coil power off, the main valve opening, medium flow. 4, Imported Nitrogen solenoid valve performance features: 1, solenoid valve internal components are made of stainless steel, made of CNC machining center, high control dimensional accuracy, good product interchangeability. 2, the Piston Ring Uses wear-resistant special material, stretch freely, will not be medium impurities stuck, with automatic gap compensation function, high dynamic sealing performance. 3, the Metal Piston and the metal valve cavity does not have the direct friction, the Piston Service Life Growth, may continue the movement million times above. 4, the valve body installation direction is not limited, vertical, horizontal, tilt can be. 5. Arbitrary coils that don't burn out easily. Reasonable sealing structure, better sealing performance. 6, long after the restart of the movement, the movement is also sensitive.
