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...
