detailed description

Below in conjunction with accompanying drawing, the utility model is further described.

As shown in Figure 2, a multi-joint pipeline pressure test device is mainly composed of a pressure pump 1, a water inlet pipe 2, a pressure relay 3, a water inlet gate valve 4, a pressure gauge with a buffer pipe 7, a branch outlet pipe 13 and The branched water pipe gate valve 9 and the pressure gauge 11 are composed. The pressure pump 1 is connected to the pressure relay 3 through the water inlet pipe 2 and the water inlet gate valve 4. The pressure gauge 7 with a buffer pipe is provided with a buffer pipe 5 and a ball valve 6. It is fixed on the Above the pressure relay 3, the pressure pump 1 injects water into the pressure relay 3 through the water inlet pipe 2 to increase the pressure, and the pressure gauge 7 with a buffer tube reflects its internal pressure. In actual work, because the internal pressure fluctuation of the pressure relay 3 is large, it will form an instantaneous impact on the pressure gauge 7 with the buffer tube, so the buffer tube 5 is installed under the pressure gauge 7 with the buffer tube. A plurality of branched water pipes 13 are fixed around the pressure relay 3, the branched water pipes 13 are flexible pipes, both ends are equipped with joints 12, one end is connected with the connecting steel pipe 8 equipped with branched water pipe gate valves 9 and pressure gauges 11, and the other One end is connected with the pressure test pipeline 10, and each pressure gauge 11 is equipped with a ball valve 6, and the connecting steel pipe 8 is fixedly connected with the pressure relay 3. The pressure relay 3 is a pressure-checked sealed cylinder, and its inner chamber has a through hole to communicate with the water inlet pipe 2 and the connecting steel pipe 8.

When it is necessary to carry out hydrostatic test on multiple pipelines with the same test pressure at the same time, open the water inlet gate valve 4 and the branch outlet water pipe gate valve 9, and turn on the pressure pump 1 to fill the pipeline with water and increase the pressure until the pressure gauge reading reaches the test pressure requirement. , close pressure pump 1, branch outlet water pipe gate valve 9 to maintain pressure. If there is no abnormality in the readings of each pressure gauge, then the pressure test is successful. If the reading of the pressure gauge on the water pipe 13 of a certain branch is abnormal, then the pipeline is checked and processed. until qualified.

When it is necessary to carry out hydrostatic tests on multiple pipelines with different test pressures at the same time, open the water inlet gate valve 4 and the branch outlet water pipe gate valve 9, and turn on the pressure pump 1 to fill the pipeline with water and boost the pressure. Pay attention to the changes in the readings of the pressure gauge 11 on each branch outlet pipe 13, and when the reading of the pressure gauge on the branch reaches the test pressure, close the branch outlet water pipe gate valve 9 on the branch to maintain pressure. Continue to pressurize other pipelines until the pressure of each pipeline reaches the test pressure respectively. If the readings of the pressure gauge 11 on each branch are normal, the test is successful. The pipeline is inspected and treated, and after the treatment is completed, the pressure test of the branch can be carried out separately until it is qualified.
