High-temperature resistant pneumatic globe valve

The utility model relates to a high-temperature resistant pneumatic globe valve. The high-temperature resistant pneumatic globe valve comprises a first valve body; the first valve body is connected with a sleeve; through holes are formed in the periphery of the sleeve wall from bottom to top, wherein the inner diameters of the through holes, within the range of 3 to 11.5 mm, are unequal to each other; the through holes are used for controlling the flow and uniformly formed in the sleeve wall; the sizes of every circle of through holes are equal to each other; a valve clack is arranged in the sleeve; the front side of the valve clack is provided with a plurality of small holes for the flow; the lateral side of the valve clack is provided with a flow line groove. According to the high-temperature resistant pneumatic globe valve, the problems that the valve clack is slow in cooling and easy to deform and damage when being heated at the high temperature are solved; the valve clack is provided with a first valve r
