Abstract

The invention discloses an electronic expansion valve. The electronic expansion valve comprises a valve base, a first pipe connecting part and a second pipe connecting part, wherein the valve base comprises a peripheral wall part and a valve port part, the electronic expansion valve comprises a first valve cavity and a second valve cavity, the first valve cavity is located on the valve port part,the second valve cavity is located below the valve port part, the valve port communicates with the first valve cavity and the second valve cavity, the first pipe connecting part is fixedly connected with the valve base and directly communicates with the first valve cavity, the second pipe connecting part is fixedly connected with the valve base, the second pipe connecting part and the valve base define the second valve cavity, and the inner diameter of the valve port is smaller than that of the second valve cavity. The electronic expansion valve comprises the first valve cavity and the secondvalve cavity, a refrigerant enters the second valve cavity after passing through the valve port from the first valve cavity, due to the fact that the inner diameter of the valve port is smaller than that of the second valve cavity, the flowing speed and pressure of the refrigerant can be reduced after the refrigerant flows through the valve port, and therefore noise generated when the refrigerantpasses through the electronic expansion valve is reduced, and the requirement of reducing the noise in some systems is met.

Description

【Technical field】 [0001] The invention relates to the technical field of refrigeration control, in particular to an electronic expansion valve. 【Background technique】 [0002] A refrigeration system usually includes a compressor, a throttling element, an outdoor heat exchanger, and other components. The throttling element can use an electronic expansion valve to regulate the flow of refrigerant. When the refrigerant enters the electronic expansion valve, some noise may be generated. The noise of the refrigerant passing through the electronic expansion valve has been a technical subject that has been studied by technicians related to electronic expansion valves and refrigeration systems for a long time. Therefore, the structure of the electronic expansion valve can be optimized to reduce the noise when the refrigerant flows through the electronic expansion valve. 【Content of invention】 [0003] The purpose of the present invention is to provide an electronic expansion val...
