Description

Straight corrugated integrated pipeline Technical Field The utility model belongs to the technical field of storage tank pipelines of flow batteries, and particularly relates to a straight corrugated integrated pipeline. Background The flow battery storage tank pipeline is a life line of energy flow and material circulation of the whole battery and bears multiple key functions of conveying, controlling (flow/pressure), connecting, monitoring, heat management, guaranteeing safety and the like, the traditional pipeline adopts two connecting modes, namely a corrugated pipe and a straight pipe, and meanwhile, the two pipelines have the following defects in the complicated flow battery pipeline: the straight pipe system depends on high-precision processing (such as welding and threaded connection), but factors such as equipment interface spacing, expansion and contraction of pipelines and the like in actual working conditions easily cause dimensional deviation, so that the installation is difficult and even leakage risks are caused; The corrugated pipe has the advantages that the turbulence degree and the along-path resistance of electrolyte (or other fluid) can be obviously increased, so that the flow speed is reduced and the energy consumption is increased; Based on the above, even if the straight pipe and the corrugated pipe are simultaneously acted in the pipeline, the corrugated pipe and the straight pipe are connected, and the transition parts such as flanges, compensators, flexible connections and the like are additionally arranged, so that the welding/bolt fixing procedure is added, the cost is high, and leakage points are easily increased due to the superposition of the parts.
