[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] Reference Figures 1 to 3 The utility model provides an embodiment: a flat floating electronic expansion valve, including a valve body 1 and a joint pipe 3. The right side of the valve body 1 is fixedly connected with a wire head, one side of the pipe mouth 2 is in contact with one side of the joint pipe 3, and the outside of the valve body 1 is fixedly connected with two pipe mouths 2. The valve body 1 here provides a stable support for the pipe mouths 2. The other end of the joint pipe 3 is fixedly connected with a connecting pipe 4. The connecting pipe 4 here is the connection point of the external device. The outside of the joint pipe 3 is slidably connected with a clamping assembly for providing a connection function. The clamping assembly includes a collar 5. The inner wall of the collar 5 is slidably connected to the outside of the joint pipe 3. The collar 5 here provides a stable support for the joint pipe 3, and the inner side of the collar 5 is slidably connected to the outside of the pipe mouth 2.

[0033] Reference Figures 3 and 4The inner wall of the collar 5 is fixedly connected to a plurality of blocks 6. Rotating the collar 5 here can drive the blocks 6 here to rotate. The outer portion of the blocks 6 is slidably connected to the outer inner wall of the nozzle 2. The inner wall of the nozzle 2 is slidably connected to a ball 7. The nozzle 2 here provides a stable sliding space for the ball 7. The outer portion of the ball 7 is in a snap-fitting relationship with the inner wall of the blocks 6. When the balls 7 and the blocks 6 are snap-fitted, the nozzle 2 and the joint pipe 3 are installed. The inner side of the balls 7 is fixedly connected to a limit block 8. The outer portion of the limit block 8 is slidably connected to the inner wall of the nozzle 2. The limit block 8 here provides a limit for the balls 7 so that they will not easily slide off the inner wall of the block 6. One side of the limit block 8 is fixedly connected to a spring 9. One end of the spring 9 is fixedly connected to one side of the inner wall of the nozzle 2. The spring 9 here can make the balls 7 tightly snap fit to the inner wall of the block 6.

[0034] Reference Figure 3 and Figure 5 , the inner wall of the joint pipe 3 is fixedly connected with an inner ring 10, and the inner wall of the pipe mouth 2 is fixedly connected with an inner box 11. The pipe mouth 2 here provides a stable support for the inner box 11. One side of the inner box 11 is in contact with one side of the inner ring 10. The inner wall of the inner box 11 is slidably connected with a rubber pad 12. The material of the rubber pad 12 here is hard rubber. One side of the rubber pad 12 is in contact with one side of the inner ring 10. One side of the rubber pad 12 is fixedly connected with a limiting ring 13. The limiting ring 13 here can prevent the rubber pad 12 from accidentally detaching from the inner wall of the inner box 11. The outer side of the limiting ring 13 is slidably connected to the inner wall of the inner box 11;

[0035] One side of the limit ring 13 is fixedly connected to a spring 2 14, and one end of the spring 2 14 is fixedly connected to one side of the inner wall of the inner box 11. The spring 2 14 here makes the contact between the rubber pad 12 and the inner ring 10 closer, thereby improving the sealing of the electronic expansion valve, thereby improving the accuracy of flow control, and further improving the operating efficiency of the entire system.

[0036] Working Principle: First, connect the other end of the connecting tube 4 to the external device. Then, rotate the collar 5, causing the clamping block 6 to rotate with it until the clamping block 6 inside the collar 5 engages with the ball 7 outside the pipe nozzle 2. When the ball 7 and the clamping block 6 are fully engaged, the pipe nozzle 2 and the joint pipe 3 are installed. At this point, the stop block 8, through the action of the spring 9, firmly engages the ball 7 with the inner wall of the clamping block 6, ensuring the stability of the connection.

[0037] Furthermore, the inner ring 10 of the connector tube 3 contacts the inner box 11 of the nozzle 2, forming a closed space. Within this space, a rubber pad 12 made of hard rubber is fixed to the inner wall of the inner box 11 and prevented from detaching by a retaining ring 13. The retaining ring 13, acting through a spring 14, maintains tight contact between the rubber pad 12 and the inner ring 10, significantly enhancing the sealing performance of the entire device. This high sealing performance ensures accurate flow control, thereby improving the overall system's operating efficiency.

[0038] In summary, the flat-plate floating electronic expansion valve achieves excellent sealing performance and flow control capabilities through its sophisticated design and structure, providing an efficient and reliable solution for refrigeration and air-conditioning systems.

[0039] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
