Abstract

The invention relates to a multichannel even-shunting electronic expansion valve. The downstream part of a refrigerant fluid channel flows to shunting outlets and are separated by a first valve arranged in a valve main body. The first valve is provided with first valve holes corresponding to all the shunting outlets. The first valve holes are provided with valve cores matched with the first valve holes. First throttling parts are formed between the valve cores and the first valve holes. The valve cores are provided with drive parts. The drive parts can drive the valve cores to advance and retreat simultaneously relative to the first valve holes, so that the opening degree of the first throttling parts is changed. The multichannel even-shunting electronic expansion valve is simple in structure and convenient to operate. The structure design from the expansion valve to a shunt loop is omitted, thus an expansion valve machine achieves a throttling effect and also has an even shunting effect, shunting accuracy is improved, and production cost is reduced.

Description

technical field [0001] The invention relates to an expansion valve, in particular to an electronic expansion valve with multi-channel equalization. Background technique [0002] In block ice making equipment, there are cases where the ice making mold is composed of multiple passages. During the ice making process, the refrigerant pressurized by the compressor is condensed in the condenser and sent to the expansion valve through the accumulator. , the refrigerant decompressed by the expansion valve is sent to the refrigerant distributor through the refrigerant piping, and is divided in the refrigerator distributor, and then sent to multiple passages of the ice-making mold. After the mold is gasified, it is returned to the compressor. In such a cycle, after the expansion valve is decompressed, the refrigerant is called a low-pressure gas-liquid two-phase flow refrigerant. When the internal flow is easy to become plug flow and plug flow containing a large number of air bubble...
