Pipeline pressure test device and pipeline pressure test system

Abstract

The invention provides a pipeline pressure test device and pipeline pressure testsystem, andrelates to the technical field of pipeline test equipment. The pipeline pressure test device comprises a pressure device, a main pressure pipe, a gauge assembly, a valve assembly and multiple connection pipes; a medium is pressed by the pressure device to enter a pipeline to be tested through a check valve,and the check valve controls the medium not to flow back; a first sluice valve separates the pipeline to be tested fromthe pressure device so as to reduce disturbance of pressure caused by the pressure devicein the pipeline to be tested; the gauge assembly is communicated with the pipeline through a second sluice valve to reduce disturbance of thepipeline system to be tested by the gauge assembly; a safety valve is communicated with the pipeline to be tested; the safety valve automatically depressurizes when the pressure of the pipeline to be tested exceeds a set pressure value, it is avoidedthat sudden change of the pressure causes damage of accessories and the valve of the tested pipeline, the damage of the tested pipeline due to the sudden change of the pressure is reduced to the maximum degree, and the technical problemsin the prior art are solved that the safety coefficient is low, the pressure stabilizing time is long and the pressure stabilizing effect and the operability arepoor.

Description

technical field [0001] The invention relates to the technical field of pipeline test equipment, in particular to a pipeline pressure test device and a pipeline pressure test system. Background technique [0002] Pressure pipelines are widely used in industrial pipelines and civil pipelines. Pipeline pressure testing after pipeline construction is the most direct and effective detection method for pipeline construction quality. The pipeline pressure test can effectively detect the strength and tightness of the welding joints and flanges, which greatly improves the success rate of the first-time startup of the system. The role of the pipeline pressure test is becoming more and more obvious. [0003] The pipeline pressure test in the prior art is to realize the pipeline pressure test by connecting the pressure pump and the test pipeline; the specific steps are to close the accessories such as the valve at the end of the pipeline after the pipeline is flushed, and pressurize the...
