Embodiment 1

[0042] A heat exchange structure of an ultra-low temperature solenoid valve, wherein, such as figure 1 As shown, it includes: valve seat 10 , moving core 20 , static core 30 , and coil 40 .

[0043] like figure 1 As shown, the valve seat 10 has a movable cavity 11 and an annular structure 13 . The movable cavity 11 is located in the valve seat 10 . The annular structures 13 are distributed on the outer surface of the valve seat 10 , and the annular structures 13 are located on the side of the movable cavity 11 .

[0044] The moving core 20 is slidably arranged in the movable cavity 11 , the moving core 20 and the side wall of the movable cavity 11 form a movement gap 12 , and heat exchange with the outside air is realized through the movement gap 12 . The static core 30 is fixedly arranged on the movable cavity 11 , and the static core 30 is located on the side of the moving core 20 . There is a gap between the static core 30 and the moving core 20 , and the static core 30 a...

Embodiment 2

[0057] A heat exchange method for an ultra-low temperature solenoid valve, comprising the following steps:

[0058] When the ultra-low temperature medium gradually flows close to the coil 40 through the moving gap 12 around the moving core 20, during this process, the medium continuously exchanges heat with the outside air when it contacts the side wall of the movable cavity 11, and the ultra-low temperature medium heats up, making the coil 40 The temperature of the medium at the place rises to the extent that the coil can withstand;

[0059] At the same time, a plurality of rings of annular structures 13 are processed on the valve seat 10, so that there is a heat exchange space between each annular structure 13, and when the outside air is passed into the heat exchange space, it can be carried out with each annular structure 13. The heat exchange greatly increases the contact area with the outside air, improves the heat exchange efficiency, and realizes the temperature rise f...

Abstract

The invention discloses a heat exchange structure of an ultra-low temperature electromagnetic valve, which relates to the technical field of ultra-low temperature gas storage devices, and comprises a valve seat, a moving core, a static core and a coil. First, by setting a movement gap between the movable cavity and the moving core, the ultra-low temperature medium flowing in the solenoid valve can continuously exchange heat with the outside air through the movement gap, and the temperature is continuously taken away from the inside. The outer surface of the heat exchanger is set into a multi-circle annular structure to form multiple heat exchange spaces, which greatly increases the contact area with the outside air, and cooperates with the interior to take away the temperature from the outside and improve the heat exchange efficiency. The distance will be shorter, which can reduce the height requirements of the solenoid valve. To solve the problem in the prior art that the ultra-low temperature electromagnetic valve will lengthen the height of the ultra-low temperature electromagnetic valve itself in order to protect the coil for air heat exchange, which limits the application range.

Description

technical field [0001] The invention relates to the technical field of ultra-low temperature gas storage devices, in particular to a heat exchange structure of an ultra-low temperature electromagnetic valve. Background technique [0002] Solenoid valve (Electromagnetic valve) is an industrial equipment controlled by electromagnetic. It is an automated basic component used to control fluids. It belongs to an actuator and is not limited to hydraulic and pneumatic. It is used in industrial control systems to adjust the direction, flow, speed and other aspects of the medium. parameter. The solenoid valve can be matched 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 most commonly used solenoid valves include check valves, safety valves, electromagnetic directional valves, and speed co...
