The double-side circulation structure comprises a shell with a side opening and a lower opening, a valve element sealed between the side opening and the lower opening is arranged in the shell, a first balance cavity communicated with the side opening is formed between the outer wall of the valve element and the inner wall of the shell, and a second balance cavity communicated with the side opening is formed between the outer wall of the valve element and the inner wall of the shell. The first balance cavity is located on the side, away from the lower opening, of the valve element, and a second balance cavity communicating with the lower opening is formed between the end, away from the lower opening, of the valve element and the shell. According to the utility model, a structural form of two balance cavities is adopted, when a medium flows in from the side port, the medium flows to the first balance cavity from the four directions of the valve core, a downward acting force is applied to the valve core and coun
