Problems solved by technology

However, the conventional multi-way reversing valve cannot be applied to the continuous extraction process, which reduces its application range
Furthermore, the design of the conventional multi-way reversing valve is relatively complicated, which may easily cause solvent leakage
[0004] In addition, because the conventional multi-way reversing valve cannot be used in the continuous extraction process, when the extraction process is performed, the extractant often has to be discharged from the system before reaching saturation, which increases the extraction cost and reduces the extraction efficiency

Abstract

The invention discloses a multi-way reversing valve. The multi-way reversing valve comprises a shell and a rotary core structure, wherein the shell is provided with at least three input pipelines and at least three output pipelines; the rotary core structure is assembled in the shell in a close fit way and comprises a connecting shaft and a body; the body is fixedly connected with the connecting shaft, is of an inversed circular truncated cone shape, and comprises an input part and an output part; the input part is arranged at the top end of the body and is provided with at least three inlets and at least three first channel structures communicated with the inlets in a one-to-one manner; the output part is arranged adjacent to the downside of the input part and comprises at least three circles of grooves and at least three second channel structures; the three circles of grooves are concentrically formed along the position, facing the downside of the body, on the connecting shaft; the diameters of the grooves are gradually reduced towards the downside of the body; each groove is provided with an outlet; the second channel structures are communicated with the outlets and the first channel structures in a one-to-one manner; the input pipelines are communicated with the inlets in a one-to-one manner and the output pipelines are communicated with the grooves in a one-to-one manner. During rotation, the connecting shaft drives the body to rotate together, and the flowing path of liquid can be changed.

Description

technical field [0001] The present invention relates to a reversing valve, and in particular to a multi-way reversing valve. Background technique [0002] In the common extraction or chromatography process, it is often necessary to use a storage tank with a large volume to store a variety of solvents to meet various extraction or chromatography processes. However, the complex process conditions and the order of adding solvents often make personnel make mistakes and cause industrial safety accidents. [0003] The general solution is to use a multi-way reversing valve to adjust the flow path of the solvent to simplify the operating conditions. However, the conventional multi-way reversing valve cannot be applied to the continuous extraction process, which reduces its application range. Furthermore, the design of the conventional multi-way reversing valve is relatively complicated, which may easily cause solvent leakage. [0004] In addition, since the conventional multi-way...
