Description

Technical Field

[0001] This utility model relates to the field of valve technology, and in particular to an electronic expansion valve oiling detection and pressing device. Background Technology

[0002] Electronic expansion valves utilize electrical signals generated by the regulated parameters to control the voltage or current applied to the expansion valve, thereby regulating the refrigerant supply. Stepless variable capacity refrigeration systems require a wide range of refrigerant supply adjustment and rapid response, which traditional throttling devices struggle to meet, while electronic expansion valves effectively fulfill these requirements. Current expansion valves require oil spraying testing and press-fitting during production. Current production equipment involves numerous steps, making it difficult to guarantee oil cleanliness. Manual testing cannot meet actual testing needs and is prone to omissions. During the press-fitting process, manual assembly makes vertical installation difficult, leading to valve body misalignment and inability to lock properly, ultimately resulting in product damage.
