Fluid pressure detection device

The utility model belongs to the technical field of pipeline pressure detection, and particularly relates to a fluid pressure detection device which comprises a bourdon tube pressure gauge body, a connecting seat is arranged at the bottom of the bourdon tube pressure gauge body, a through groove is formed in the connecting seat, a plurality of connecting frames are arranged on the outer side of the connecting seat, and the connecting frames are connected with the bourdon tube pressure gauge body. A fixing ring plate is arranged on the outer side of the bottom of the connecting base, a plurality of telescopic rods are arranged at the bottom of the fixing ring plate, and the outer threaded pipe and the flow guide pipe can be buffered through the telescopic rods, springs and telescopic air bags. According to the bourdon tube pressure gauge, the influence of vibration of the pipeline and the external threaded pipe on the bourdon tube pressure gauge body can be reduced while the smoothness of a flow channel betwee
