The stator component is cylindrical in appearance, a rectangular junction box and a junction box cover are arranged on one side of the circumference, compared with the traditional stator structure, the stator component is only provided with a slot for mounting a positioning arm at the position of the junction box, and the metal of a stator framework on the inner side of the slot is exposed and is used as a welding point fixedly connected with the positioning arm. The valve body appearance be round platform step form, the shoulder hole is established to the inner chamber, its difference with traditional valve body is equipped with the a set of locating hole that corresponds with the locating head on the circumference in valve body and rotor part border region. When the electronic expansion valve is installed, the stations can be fixed in the selected direction according to the working conditions under the action of the positioning head and the positioning hole.
Description
Technical Field
The utility model relates to a simple and easy location structure of electronic expansion valve rotor stator.
Background
The existing electronic expansion valve rotor stator positioning structure is roughly divided into two modes of directional fixation with only one fixed position and direction selection fixation for selecting a plurality of fixed positions, however, the structure of each mode has various types, and the structure characteristics of the direction selection fixed mode are that most of them are that a fixed frame with selectable gears is arranged on the expansion valve rotor, a positioning head corresponding to a positioning hole of the fixed frame gear is arranged on the end surface of the expansion valve stator, and the relative position of the positioning head and the positioning holes can be changed by rotating the rotor stator during assembly, so as to be beneficial to the installation and debugging of equipment. Generally, the structure of the directional fixed mode is relatively complex, the manufacturing cost is higher than that of the directional fixed mode, and users often select an economical and practical structural mode according to working condition requirements. Therefore, optimizing the product structure, reducing the production cost and improving the economic benefit are the constant subjects of people.
Disclosure of Invention
The utility model discloses the system is selected to the optimization structure of fixed mode, does the comparison with traditional type, and it will be originally the location head of arranging perpendicularly and design into the level and arrange, fixes on stator part through the registration arm to directly set up the locating hole that corresponds with it on the circumference that the valve body corresponds, its advantage has saved the mount, has simplified the preparation process, thereby has reduced manufacturing cost, has enlarged the competitive advantage.
The utility model discloses constitute by location arm, location head, stator part, junction box cover, rotor part, valve body. The positioning arm is a Z-shaped metal stamping part, one end of the positioning arm is provided with a mounting hole for fixing the positioning head, the other end of the positioning arm is provided with a welding cavity for fixedly connecting the stator part, and the center line of the middle section of the positioning arm is provided with a long groove, so that the rigidity of the middle section of the positioning arm is weakened to increase the elastic deformation of the positioning arm. The positioning head is a round head rivet-shaped part and is made of metal materials. The stator part is cylindrical in appearance, a rectangular junction box and a junction box cover are arranged on one side of the circumference, a through hole for mounting the rotor part is formed in the center of the stator part, compared with the traditional stator structure, only a slot for mounting a positioning arm is formed in the junction box, and the metal of a stator framework on the inner side of the slot is exposed and serves as a welding point fixedly connected with the positioning arm. The valve body appearance be round platform step form, the inner chamber is established the shoulder hole, is equipped with parts such as disk seat, needle, the valve body upper end is connected with the rotor part, the lower extreme is equipped with the refrigerant output tube, the valve body middle part position is equipped with the refrigerant input tube, its difference lies in being equipped with a set of locating hole that corresponds with the locating head on the circumference of valve body and rotor part border region with traditional valve body. When the electronic expansion valve is installed, the stations can be fixed in the selected direction according to the working conditions under the action of the positioning head and the positioning hole.
