Pipeline pressure testing system and method

Abstract

The invention discloses a pipeline pressure testing system and method.The pipeline pressure testing system comprises a water feeding pump, a pressurizing pump, pressure testing pipelines, fixing pieces, a safety valve return pipe, and a pressure-resisting distribution pipe with an inlet connected with the pressurizing pump and the water feeding pump.The pressure-resisting distribution pipe is communicated with a plurality of connecting pipes, two ball valves and a safety valve are arranged on each connecting pipe in sequence, and the tail end of each connecting pipe is connected with the corresponding pressure testing pipeline.The pipeline pressure testing method includes the steps that firstly, the pressure-resisting distribution pipe and the safety valve return pipe are fixed; then, water is fed into the pressure testing pipelines under the action of control valves and the ball valves; the pressure testing pipelines are pressurized after water feeding is finished.By means of the pipeline pressure testing system and method, simultaneous water feeding and pressurizing at different pressure grades are achieved, and thus the labor intensity of workers is relieved; all steps achieve the mutual effect in the pressure testing process, and thus pressure testing accuracy is improved; meanwhile, the service life of equipment is effectively prolonged, and the later-period maintenance cost is reduced.

Description

technical field [0001] The invention belongs to the field of pipeline pressure testing, and in particular relates to a pipeline pressure testing system and method. Background technique [0002] When checking and accepting the pipeline, it is necessary to carry out a pressure test on the pipeline. The existing pipeline pressure test method is to test the pressure of pipelines with different pressure levels separately. When the number of pipelines is large, the pressure test process is cumbersome and consumes a lot of manpower and time. [0003] The patent document with publication number 204556399U discloses a multi-stage self-control pipeline pressure test device, which includes a water inlet pipeline and a water distribution pipeline connected to the water inlet pipeline. The water distribution pipeline is connected to the pressure source interface. When the pressure is detected to reach Automatically shuts off when the pressure level is reached. However, during the worki...

Problems solved by technology

However, during the working process of the pressure test device, the phenomenon of pipeline vibration will occur, which will greatly interfere with the pressure test of the pipeline, which is not conducive to improving the accuracy of the pressure test; and under the action of the interference, it is easy to cause the pressure to exceed the pressure level. , because there is no suitable pressure relief device in this pressure test device, safety accidents are likely to occur
