Pipeline pressure gauge assembly

The utility model relates to a pipeline pressure gauge assembly. At present, the replacement steps of an existing pressure gauge are quite tedious, and the pressure gauge is connected with a pipeline in a welding connection mode instead of a nut connection structure. A pipeline pressure gauge assembly comprises a first connecting pipe (1), the bottom of the first connecting pipe is fixedly connected with a pipe shell (4), the outer side wall of the pipe shell is fixedly connected with first clamping grooves (11) in bilateral symmetry, the bottom of the outer side wall of the pipe shell is fixedly connected with first clamping blocks (10) in bilateral symmetry, and a valve pipe (9) is arranged at the bottom of the pipe shell. The upper portion of the outer side wall of the valve pipe is fixedly connected with second clamping grooves (12) which are symmetrical left and right, the upper portion of the outer side wall of the valve pipe is fixedly connected with second clamping blocks (13) which are symmetrical le
