Problems solved by technology

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. The electronic expansion valve must be reset before the test, resulting in waste of manpower and increased costs.
In addition, due to the vibration during transportation, the valve core and valve port of the electronic expansion valve may collide and rub for a long time, which will affect the control accuracy of the electronic expansion valve and shorten its service life.

Embodiment 1

[0028] Such as figure 1 As shown, the main body is a snap ring 1, and the snap ring has two surrounding parts 11 used to surround and embrace the valve body of the electronic expansion valve as a positioning structure. The two surrounding parts are connected to form two joints. In order to ensure that the two valves After the bodies are fixed, they can be parallel to each other, so the central axes of the two surrounding parts are parallel, the valve bodies of the two electronic expansion valves cooperate with the surrounding parts one by one, and the two valve bodies are oppositely fixed in the surrounding parts. The communication between the two surrounding parts of the clasp makes the valve bodies of the two electronic expansion valves contact. It needs to be explained that the communication between the two surrounding parts means that the small area surrounded by the two surrounding parts is connected to each other and becomes a large one. area, combined figure 2 Clearer...

Embodiment 2

[0031] Such as Figure 6 As shown, the main body in this embodiment is a plate body 2, and the plate body is provided with two positioning grooves 21 as a positioning structure. The two positioning grooves are arranged in parallel and run through both ends of the plate body. The grooves are matched one by one and the two valve bodies are fixed in the positioning grooves oppositely. It is also for the maximum magnetic force that the magnetic rotors inside the two valve bodies attract each other, so the two positioning grooves of the plate are connected to make the valve bodies of the two electronic expansion valves contact. In fact, the principle of this embodiment is the same as that of Embodiment 1.

Embodiment 3

[0033] Such as Figure 7 As shown, in this embodiment, the main body is a plate body 2, and the positioning structure is a positioning frame 22 provided with two positioning grooves 21. The positioning frame is fixed on the plate body, and the two positioning grooves are arranged in parallel and run through both ends of the positioning frame. The valve bodies of the two electronic expansion valves cooperate with the positioning grooves one by one, and the two valve bodies are fixed in the positioning grooves facing each other. The communication between the two positioning slots of the positioning frame makes the valve bodies of the two electronic expansion valves contact each other, so that the magnetic force of the magnetic rotors inside the two valve bodies attracts the maximum. Since the plate body occupies a larger space than the positioning frame, it can occupy a certain storage space for the electronic expansion valve, which is convenient for stacking and storing multipl...

Abstract

The invention discloses a fixing frame for electronic expansion valves. The fixing frame is a transportation and storage auxiliary tool, and the problem of deviation of valve spools in electronic expansion valve transportation procedures can be solved by the aid of the fixing frame. The technical scheme mainly includes that the fixing frame comprises a body; positioning structures which are used for simultaneously fixing the two electronic expansion valves are arranged on the body. The fixing frame has the advantages that valve bodies of the two electronic expansion valves can be oppositely fixed into the positioning structures, and accordingly the fixing frame can be used for fixing and storing the electronic expansion valves during transportation.

Description

technical field [0001] The invention relates to the transportation and storage of an electronic expansion valve, in particular to an electronic expansion valve fixing frame. 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 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 te...
