Dynamic voltage stabilizer

The utility model relates to a dynamic pressure stabilizing device which comprises a first container connected to a feeding pipe and communicated with the interior of the feeding pipe, and the first container is not communicated with atmospheric pressure; the second container is a sealed container arranged in the first container, liquid or gas is contained in the second container, the second container comprises at least one flexible side wall capable of generating deformation, and the second container is communicated with a squeezing cavity through a pressure stabilizing pipe and is used for being squeezed by the feed liquid in the first container when the pressure in the feed pipe is increased; and liquid or gas is introduced into the squeezing cavity. The device has the effects of dynamically balancing the pressure of the squeezing cavity and the filter chamber and reducing the damage probability of the filter plate caused by overlarge feed liquid conveying pressure. 本申请涉及一种动态稳压装置，其包括第一容器，连接在进料管上且与进料管内部连通，所
