AI Technical Summary

Technical Problem

Large energy station equipment is prone to water hammer effect and instantaneous pressure shock during the medium transportation process, which can lead to pipeline vibration, loose connections and local deformation, affecting the stability and safety of equipment operation.

Method used

The system employs a progressive flow guiding mechanism and a spiral guide structure. Through the flow guiding mechanism composed of a deceleration sleeve, a guide sleeve, and a rectangular hole, the medium flow rate is progressively adjusted. An insulation sleeve and a constant temperature tank are installed on the outside of the output pipe to form a circulating temperature control structure, reducing the impact caused by sudden pressure increases and temperature differences.

Benefits of technology

It effectively reduces water hammer effect, decreases impact load, improves the stability and reliability of pipeline systems, prevents latent cracks caused by thermal stress, and extends the service life of the equipment.

Abstract

The invention relates to the technical field of pipe fitting arrangement devices, in particular to a large energy station equipment pipe fitting arrangement device which comprises an installation frame, the installation frame is of a frame type bearing structure, a supporting ring is fixedly installed at the inner end of the installation frame, two distribution pipes are fixedly installed at the inner end of the supporting ring, and a plurality of output pipes are fixedly installed on the outer surfaces of the distribution pipes. According to the invention, a progressive flow guide mechanism composed of a speed reduction sleeve, a guide pipe, a rectangular hole and other structures is arranged in the output pipe, when a medium enters the output pipe from the distribution pipe, the speed reduction sleeve gradually moves under the action of medium pressure, so that the circulation cross section of the output pipe is gradually increased; therefore, the medium flow is gradually adjusted from small flow to large flow, pressure sudden increase caused by the fact that the medium instantly enters the pipeline is avoided, the water hammer effect in a pipeline system can be effectively reduced, the impact load is reduced, and the operation stability of the pipeline system is improved.
