A pipeline circuit switching device for a refrigeration unit of a freezing station

Abstract

The utility model relates to pipeline switching technical field, concretely is a kind of pipeline loop switching device for refrigeration station refrigerating unit, including first transfer pipe, the bottom of first transfer pipe is fixedly connected with second transfer pipe by multiple connecting arms, first transfer pipe and second transfer pipe between still fixedly installed with the adjusting mechanism that can be adjusted conveying path, and adjusting mechanism can also reduce the impact force brought when water flow flows, the bottom of second transfer pipe is fixedly installed with installation fixing mechanism, when needing to continue to limit and fix second transfer pipe, realize pipeline switching by rotating handle, both A, B unit can let the salt water overall cooling of liquid storage tank and auxiliary tank directly, C, D, E unit can also make the low-temperature salt water after A, B precooling extraction, avoid the load overproof problem when five units are started simultaneously, greatly shorten refrigeration time, improve refrigeration efficiency, reduce the loss caused by long-term high load operation of unit simultaneously.
