Manifold assembly and purging control method

The invention discloses a manifold assembly and a purging control method, and relates to the technical field of oil and gas fracturing. A manifold assembly comprises a low-pressure manifold and a flexible pipe. The fracturing equipment comprises a fracturing pump and a manifold connector, the fracturing pump is provided with a liquid feeding opening, the first end of the low-pressure manifold is connected to the fracturing pump and communicated with the liquid feeding opening, the second end of the low-pressure manifold is connected with the first end of the flexible pipe, the second end of the flexible pipe is connected to the manifold connector, and the first end of the low-pressure manifold is communicated with the liquid feeding opening. And the pipeline is communicated with the manifold joint. The purging control method is applied to the manifold assembly. The problem that the liquid feeding opening and the manifold are damaged or leaked due to vibration at least can be solved. 本申请公开了一种管汇组件及吹扫控制方法，涉及油气压裂
