Wellhead throttle valve circulating cooling device

The utility model relates to the technical field of cooling and heat exchange, in particular to a circulating cooling device for a wellhead throttle valve. Comprising a first water tank and a second water tank, a throttle valve body is arranged in the second water tank, two connecting pipes are arranged between the first water tank and the second water tank, and the first water tank and the second water tank form a circulation path through the connecting pipes; the connecting pipes are respectively a first connecting pipe and a second connecting pipe, and the water flow direction of the circulating path is that liquid in the first water tank flows into the second water tank through the first connecting pipe; then, liquid in the second water tank flows into the first water tank through the second connecting pipe; a refrigerator is arranged on the first connecting pipe and used for cooling liquid flowing through the first connecting pipe. According to the circulating cooling device for the throttle valve, physi
