Temperature reducing device for protecting steam pipeline

The utility model discloses a temperature reducing device for protecting a steam pipeline. the device comprises a steam pipeline and nozzles, the number of the nozzles is two. An included angle of 90degrees is formed in the same cross section, and the cross section is arranged on the steam pipeline in a penetrating manner; wherein a bushing is arranged in the steam pipeline, the bushing and the steam pipeline are coaxially arranged, the outlet part of the nozzle extends into the bushing, the inlet part of the nozzle is positioned outside the steam pipeline, and the inlet part of the nozzle isprovided with a flange plate connected with a temperature reducing water pipe. The steam pipeline has the advantages that desuperheating water is prevented from being directly sprayed to the inner wall of the pipeline, the spray desuperheating effect is improved, and finally the major potential safety hazard that the steam pipeline generates plastic deformation is avoided. 本实用新型公开了一种保护蒸汽管道的减温装置，其特征在于：包括蒸汽管道、喷嘴，其中所述喷嘴数量为两个
