Problems solved by technology
[0003] The above-mentioned electric switching valves are directly welded on the slide plate with copper tubes. Welding will easily cause the deformation of the slide plate, resulting in poor sealing between the slide block and the slide plate. The processing technology of the slide plate is complicated, which is not conducive to mass production and control of product defect rate.
In addition, there are many types of electric valves of this type, each valve has only four working states, and the interchangeability is poor.

Embodiment Construction
[0052] The present invention will be described in further detail below in conjunction with the accompanying drawings of the description.
[0053] Such as figure 1 As shown, the electric switching valve of the present invention consists of three parts: a valve body 1 , a stator component 2 , and a mounting bracket 3 .
[0054] Such as Figure 13 As shown, the mounting bracket 3 is provided with three mounting bracket riveting positions 3a, a large through hole 3b, and a small through hole 3c.
[0055] combine figure 1 with Figure 13 , the valve body 1 and the stator part 2 are riveted and connected with the three mounting bracket riveting positions 3a on the mounting bracket 3 through the three metal bosses 2a on the stator part 2, wherein the outlet pipe C1914 in the valve body 1 passes through the mounting bracket 3 The small through hole 3c on the top, the inlet pipe A1911, the outlet pipe B1912, and the outlet pipe D1913 pass through the large through hole 3b on the mo...

The invention discloses an electric switching valve which comprises a valve body, a stator part and an installation bracket. The valve body comprises a valve shell, a motor rotor, a slide block, a slide plate and a valve seat assembly. The valve seat assembly comprises a valve seat and an inlet pipe A, three outlet pipes B, C and D. The slide plate is provided with a liquid inlet hole a, and three liquid outlet holes b, c and d. The liquid inlet hole a is aligned with the liquid inlet hole A on the valve seat, and the three liquid outlet holes b, c and d are aligned with the three liquid outlet holes B, C and D. The slide block is provided with three flow grooves, and when the motor rotor rotates, the slide block is driven to rotate. In the rotary process of the slide block, the three flow grooves can be respectively communicated with one liquid inlet hole a and the three liquid outlet holes b, c and d, so that various working states can be realized. The electric switching valve has the beneficial effects that the processing difficulty of the slide plate is solved and the process of product is improved, so that the valve is appropriate for batch production. The difficulty of poor interchangeability of the electric switching valve is solved. The electric switching valve has various working states, so that different manufacturers can realize different control requirements just by adjusting a driving program.
Description
technical field [0001] The invention belongs to refrigeration technology, in particular to an electric switching valve for refrigeration, freezing and temperature-variable refrigerators. Background technique [0002] Chinese patents CN100478596C, CN101275678B, CN101270826B, CN101230928B, and CN100478596C disclose several electric switching valves, which are all driven by a stator component to rotate the motor rotor, and the motor rotor drives the slider to rotate, and the slider rotates relative to the slide plate. Groove or hole or groove, when this groove or hole or groove is aligned with the valve port on the slide plate, the outlet pipe that is connected on this hole just conducts. By controlling the number of pulses input to the stator part to control the rotation of the slide block, the on-off switching of one inlet pipe welded on the slide plate and two or more outlet pipes is realized. [0003] The above-mentioned electric switching valves are all directly welded on...
