AI Technical Summary

Technical Problem

The existing mechanical valves are linked to the refrigeration and heating components, which means that the mechanical valves cannot switch when the refrigeration and heating components fail. In addition, the numerous parts result in low assembly efficiency and easy wear.

Method used

The system employs a solenoid valve based on solid-state spring-loaded refrigeration. Through control logic combining electromagnetic drive with elastic element reset, switching is determined by the energization/de-energization of the electromagnetic drive. The rod moves by magnetic attraction and elastic force to achieve pipeline switching, avoiding reliance on component stroke signals.

Benefits of technology

Even if the cooling and heating components malfunction, the solenoid valve can independently complete the switching, avoiding the failure of mechanical valve switching, reducing the number of parts, improving assembly efficiency, and avoiding mechanical wear.

Abstract

The utility model provides a kind of electromagnetic valve based on solid-state elastic card refrigeration, belong to electromagnetic valve technical field, including valve main body, connecting pipe group and switching execution component. First chamber and second chamber are sequentially communicated in valve main body inside;Connecting pipe group includes first pipeline, second pipeline and third pipeline, the side wall of second chamber is communicated to first pipeline, the side wall of first chamber is communicated to second pipeline, and one end of third pipeline is communicated to second chamber away from first chamber direction;Switching execution component includes electromagnetic drive part and stem, one end of stem is inserted into second chamber and is connected with plugging part, and the other end of stem is provided with elastic member. The utility model provides a kind of electromagnetic valve based on solid-state elastic card refrigeration, when power on, magnetic attraction stem overcomes elastic force to move and realize that first pipeline is communicated with third pipeline, when power off, elastic member pushes stem to move and realize that first pipeline is communicated with second pipeline. This electromagnetic valve can replace mechanical valve, ensure switching its function, and assembly is simple, not easy to wear.
