Water supply pipeline pressure test process

Abstract

The invention discloses a water supply pipeline pressure test process. The process comprises the steps of pressure test preparation, pipeline pressure test water injection, pipeline pressurization, standing observation and pressure test device dismounting. The pipeline assembly has the beneficial effects that the pressure gauges are installed on the main water pipe, the branch water pipes and the branch water pipes correspondingly so that the pressure values of all the pipelines of the whole pipeline assembly can be monitored, the accuracy of the monitored pressure values can be ensured, connecting pieces used for being connected with the pressure gauges do not need to be additionally installed on the pipelines, and rapid construction and installation are facilitated; the exhaust valve is installed at the water outlet end of the branch water pipe with the highest horizontal height, the stop valve is installed at the position of a pipe opening connected with the exhaust valve, air in the pipeline assembly can be exhausted in the water injection process, meanwhile, when water flows out of the exhaust valve, it is indicated that the pipeline assembly is filled with water, and then the branch water pipe can be plugged through the stop valve. And water injection cleaning is carried out on the pipeline assembly after pressure testing, and it is ensured that residual objects in the pipeline are cleaned up so that the pipeline can be delivered to a user for use.

Description

Technical field [0001] The present invention relates to a pipe trial pressure device, specifically a water supply pipe test process, belonging to the field of water pressure safety testing. Background technique [0002] The test test of the water supply pipe is one of the important testing methods of supervision projects. At present, the water supply pipeline arrangement of all kinds of buildings in my country is relatively concentrated. The large number of pipes need to be assembled through the connectors, in order to ensure the performance of the pipeline and connect The sealing property needs to be tested for water pressure or air pressure on the tube. [0003] For the existing water supply pipeline test construction, there is more to be filled with water within the pipe, and then still observe whether there is water to ooze, which can only pass the artificial judgment to ensure the sealing of the connection of the pipeline, However, due to the different material properties of...

Problems solved by technology

[0003] For the existing water supply pipeline pressure test construction method, it is mostly to fill the pipeline with water, and then observe whether there is water seepage. It can only ensure the tightness of the joint of the pipeline through artificial judgment. Due to the different material properties of the pipes, the pipes will expand after being pressurized. Although there is no water flowing out, they cannot meet the normal use requirements. That is, most of the existing pressure test methods are not accurate. In addition, after the pressure test is over, There is a lack of cleaning of the pipelines. Since most of the water supply pipelines used for pressure testing are used to supply water to residents or users, some residues will accumulate in the pipelines after the pressure testing, which poses certain safety hazards to water users.
