Problems solved by technology
Since the positioning structure of the fixed frame of this patent application runs through the entire plate body, it only plays the role of fixing the expansion valve, but does not play the role of dustproof; and additional fixed frames are required, thereby increasing the packaging cost, and, After using it to pack the expansion valve, the two expansion valves are placed facing each other, which causes the packaged expansion valve to occupy a large space, which is not convenient for packaging and transportation, thus greatly increasing the cost of packaging and transportation

Embodiment Construction
[0019] The present invention is a packaging structure for an electronic expansion valve, such as Figures 1 to 2 As shown, it includes at least two dustproof caps 1 (one end of which is open and the other end is closed, which is equivalent to a blind hole type or U-shaped), and a connecting arm 2 connected between two adjacent dustproof caps 1; The above-mentioned dust cap 1 is sleeved outside the connecting pipe 31 of the electronic expansion valve 3; center distances are equal. Since there are two connecting pipes 31 of the electronic expansion valve, one of which is an intake connecting pipe and the other is an air outlet connecting pipe, such as image 3 , 4 As shown, two sets of packing structures are needed to pack the same set of expansion valves.
[0020] Since the packaging structure adopts the dustproof cap set outside the port of the connecting pipe of the electronic expansion valve, it can play the role of dustproof and moistureproof; in addition, because the ce...

The invention discloses a packaging structure. The packaging structure adopts dustproof caps coating ports of connecting pipes of electronic expansion valves to achieve the effects of preventing dust and moisture; in addition, as the center distance between the adjacent dustproof caps is equal to the center distance between the connecting pipes between two expansion valves adhered together in the same direction and level, so that when the adjacent two expansion valves are adhered together through rotor valve cores in shells thereof, the adjacent two dustproof caps of the same packaging structure rightly coat the connecting pipes of the adjacent two expansion valves, and two sets of packaging structures can be used for respectively fixing intake connecting pipes and exhaust connecting pipes of the adjacent two expansion valves, thereby preventing the condition of valve core position deviation caused by vibration in the transportation process. Therefore, the re-debugging is not needed, the labor is saved, the cost is reduced, and the packaging structure is more reasonable in structure, and facilitates packing and transporting of the electronic expansion valves.
Description
technical field [0001] The invention relates to a valve, in particular to an electronic expansion valve for controlling fluid flow. Background technique [0002] At present, electronic expansion valves are commonly used as throttling control components in frequency conversion air conditioning systems. Electronic expansion valves control the movement of the valve core through pulse signals, and have the characteristics of high control precision and remote control. The electronic expansion valve manufacturer will adjust the valve core to the designated factory position when the product leaves the factory, and it can be directly connected and tested when it is transported to the air conditioner manufacturer for assembly. However, due to the vibration during transportation, the position of the valve core will be shifted, causing the air conditioner manufacturer to fail to test normally, and the electronic expansion valve must be reset before the test, resulting in waste of manpo...
