Detailed Description
The invention provides an electronic expansion valve fixing frame which comprises a main body, wherein the main body can simultaneously fix two electronic expansion valves, and because the valve cores are fixed by utilizing the mutual attraction of magnetic rotors in two valve bodies, the valve bodies need to be fixed in opposite directions. The structure of the main body has various forms, which will be described in detail below.
The first embodiment is as follows:
as shown in fig. 1, the main body is a snap ring 1, the snap ring has two surrounding portions 11 as positioning structures for surrounding and embracing the valve body of the electronic expansion valve, the two surrounding portions are connected to form two joints, and in order to ensure that the two valve bodies can be parallel to each other after being fixed, the central axes of the two surrounding portions are parallel, the valve bodies of the two electronic expansion valves are matched with the surrounding portions one by one, and the two valve bodies are fixed in the surrounding portions in opposite directions. The two surrounding parts of the snap ring are communicated to enable the valve bodies of the two electronic expansion valves to be in contact, and it should be noted that the communication between the two surrounding parts means that small areas surrounded by the two surrounding parts are mutually connected to form a large area, which is clear by combining fig. 2. Because the magnetic rotors in the two valve bodies attract each other to fix the valve core, the closer the valve bodies are, the larger the magnetic force of the attraction is, and the best is that the two valve bodies are in direct contact, so that the valve core is best in fixing effect. In order to facilitate the valve body to be installed in the surrounding portion and to open the surrounding portion, the opening 12 is provided at one of the joints, so that the surrounding portion can be deformed greatly. In this embodiment, the width of the snap ring is determined as required, and does not exceed the height of the valve body (see dimension H in fig. 9), the wider the snap ring is, the better the effect of fixing the valve body is naturally, and the width of the snap ring is the distance from the upper end surface (visible) to the lower end surface (invisible) of the snap ring in fig. 1 (see dimension W in fig. 1).
It is of course also possible to provide the snap ring as a closed ring, as shown in fig. 3, so that the resistance during installation is correspondingly increased due to the smaller deformation of the surrounding part. If the area enclosed by the two surrounding parts is not communicated, the opening can be formed in other parts of the surrounding parts, as shown in fig. 4, and the opening is formed in the part, away from each other, of the two surrounding parts, so that the valve body is convenient to install, the influence on the mutual attraction of the magnetic rotors is small, and the valve body is convenient to manufacture due to the symmetrical structure. If the strength of the snap ring is considered, the structure shown in fig. 5 can be adopted, the snap ring is a closed ring body, and the area enclosed by the two surrounding parts is not communicated, so that the strength of the snap ring is highest.
Example two:
as shown in fig. 6, the main body in this embodiment is a plate body 2, 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 the two ends of the plate body, the valve bodies of the two electronic expansion valves are matched with the positioning grooves one by one, and the two valve bodies are fixed in the positioning grooves in opposite directions. Similarly, the magnetic rotors in the two valve bodies attract each other to have the maximum magnetic force, so that the two positioning grooves of the plate body are communicated to enable the valve bodies of the two electronic expansion valves to be in contact. In fact, the principle of the embodiment is communicated with that of the first embodiment.
Example three:
as shown in fig. 7, the main body in this embodiment is a plate body 2, the positioning structure is a positioning frame 22 provided with two positioning grooves 21, the positioning frame is fixed on the plate body, the two positioning grooves are arranged in parallel and run through the two ends of the positioning frame, the valve bodies of the two electronic expansion valves are matched with the positioning grooves one by one, and the two valve bodies are fixed in the positioning grooves in opposite directions. The two positioning grooves of the positioning frame are communicated to enable the valve bodies of the two electronic expansion valves to be in contact, so that the magnetic force of the magnetic rotors in the two valve bodies which are mutually attracted is the largest. Because the plate body occupies a larger space than the positioning frame, the plate body can occupy a certain storage space for the electronic expansion valve, so that the plurality of fixing frames can be conveniently stacked and stored.
Example four:
as shown in fig. 8, the main body of the present embodiment is a plate body 2, two through holes 23 penetrating through the upper and lower surfaces of the plate body are provided as positioning structures on the plate body, the two through holes are disposed close to each other, and most preferably, the two through holes of the plate body are communicated with each other to make the valve bodies 8 of the two electronic expansion valves contact with each other, as shown in fig. 9. The valve bodies of the two electronic expansion valves are matched with the through holes one by one, and the two valve bodies are oppositely fixed in the through holes. The advantage of using the plate as the main body can be seen from fig. 10, which presents the advantage of orderly stacking, thereby facilitating storage, fast stacking speed, and observing the condition of the electronic expansion valve individually, which is also the advantage of the third embodiment.
Other embodiments of the present invention than the preferred embodiments described above, and those skilled in the art can make various changes and modifications according to the present invention without departing from the spirit of the present invention, should fall within the scope of the present invention defined in the claims.
