Abstract

The invention relates to a pressure testing device for a pipeline. The device comprises a connecting pipe, a pressure detector, a rough adjusting device, a fine adjusting device and a first control valve, wherein the connecting pipe is used for connecting the pipeline to be tested; the pressure detector is used for detecting the pressure in the connecting pipe; the rough pressure regulating deviceis used for conveying testing liquid to the connecting pipe and the pipeline to be tested in order to enable the connecting pipe and the pipeline to be tested to be full of liquid and keep the innerpressure at first preset pressure value; the fine pressure regulating device is used for conveying the testing liquid to the connecting pipe and the pipeline to be tested in order to enable the innerpressure of the connecting pipe to increase from the first preset pressure value to the second preset pressure value which is beyond the first preset pressure value; the first control valve is arranged at the connecting pipe and is used for opening and closing communication between the pipeline to be tested and the rough pressure regulating device as well as the communication between the pipelineto be tested and the fine adjusting device. The pressure testing device is wide in pressure regulating range, high in accuracy, and more intuitive in leaking condition observation.

Description

technical field [0001] The invention relates to the technical field of pipeline testing equipment, in particular to pressure testing equipment for pipelines. Background technique [0002] The pipeline process system is a commonly used transportation process at present. The pipeline refers to the pipeline connected with the pump, valve and control device, which is used to transport liquid, gas or powdery solid. Since the pipeline process system is used to transport substances, there will be a certain pressure in the pipeline when the system is running. If it is operated directly after the installation and connection of pipelines and other structures, especially for large-scale or important pipeline process systems, it may cause equipment damage, resulting in large economic losses. Contents of the invention [0003] Based on this, it is necessary to address the problem that direct operation after the installation and connection of the existing pipeline process system may ca...
