Problems solved by technology

Every time the compressor is stopped and restarted, it will generate a large startup power consumption, and at the beginning of each startup, high-temperature refrigerant will first enter the evaporator and heat up first, and then refrigerate after reaching the conditions of the refrigeration cycle, saving energy. Flow is achieved using capillary tubes

Embodiment Construction

[0022] In order to make those skilled in the art better understand the technical solutions of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] Please refer to figure 1 , figure 1 It is a schematic cross-sectional view of an embodiment of the present invention. like figure 1 As shown, the electric valve provided in this embodiment includes a valve body 1 and a stator coil (not shown in the figure). The valve body 1 includes a valve seat assembly 11 , a rotor 12 , and a valve shaft 14 . The stator coil of the electric valve is connected to the drive controller. After the drive controller is energized, it will send a pulse drive signal to the stator coil, and the stator coil generates a periodically changing magnetic field, thereby driving the rotor 12 of the electric valve to rotate forward or reverse.

[0024] The rotor 12 is fixedly connected with the sun ge...

Abstract

An electric valve is characterized in that the electric valve comprises a valve body, and the valve body comprises a valve seat assembly, a sleeve part and a valve shaft; the valve seat assembly is in fixed connection or limited connection with the valve shaft, and the valve seat assembly is fixedly connected with the sleeve part; the valve seat assembly comprises a valve seat body part and a partition plate part, the valve seat body part comprises a first connecting pipe mounting part and a second connecting pipe mounting part, and the first connecting pipe mounting part and the second connecting pipe mounting part penetrate through the valve seat body part; the partition plate part comprises a partition plate body, a through partition plate part through hole is formed in the partition plate body, the partition plate part and the valve seat body part are welded and fixed, and at least part of the second connecting pipe mounting part is opposite to the partition plate body. According to the electric valve provided by the embodiment of the invention, a high-pressure refrigerant flowing in from the second connecting pipe cannot directly rush into the valve cavity, so that the direct impact of the high-pressure refrigerant on the gear sliding block can be reduced, and the working stability of the electric valve can be improved.

Description

【Technical field】 [0001] The invention relates to the technical field of refrigeration control, in particular to an electric valve. 【Background technique】 [0002] Refrigerator and other refrigeration equipment are widely used in various occasions. Taking a refrigerator as an example, each temperature zone of the refrigerator is controlled according to a certain interval of the preset temperature, that is, intermittent refrigeration. When the preset temperature is reached, the compressor stops; When the actual temperature of the temperature zone is higher than the preset temperature, the compressor starts to perform refrigeration, so that the temperature of the temperature zone reaches the preset temperature. Every time the compressor is stopped and restarted, a large startup power consumption will be generated, and at the beginning of each startup, high-temperature refrigerant will first enter the evaporator to heat up first, and then refrigerate after reaching the conditio...
