Pipe network hydraulic detection device

Abstract

The invention relates to the field of hydraulic pipe application, and discloses a pipe network hydraulic detection device. The pipe network hydraulic detection device is characterized in that the pipenetwork hydraulic detection device comprises a main body pipe (1), a conveying pipe (2) and a conveying mechanism installed at a pipe opening of the conveying pipe (2), and the two ends of the main body pipe (1) are connected with a movable connector (3) and a fixed connector (4) which can be in threaded connection with the two sides of a detection part of a to-be-detected pipeline respectively.The conveying pipe (2) is communicated with the middle of the main body pipe (1), an etalon is conveyed into the conveying pipe (2) through the conveying mechanism, and a probe of the etalon faces downwards and is located at the joint of the main body pipe (1) and the conveying pipe (2). According to the invention, the standard device can be stably transmitted to a verification position, parameterchange caused by the fact that a probe of the standard device touches the inner wall of the conveying pipe can be effectively avoided, the placement position of the standard device can be flexibly adjusted, and the situation of inaccurate measurement result caused by standard device fluctuation due to manual operation is reduced.

Description

technical field [0001] The invention relates to the application field of hydraulic pipes, in particular to a pipe network hydraulic detection device. Background technique [0002] In today's pipeline industry, if you want to measure the pressure of the liquid in the pipeline, you usually reserve the measurement section of the pipeline in the required measurement section when installing the pipeline. When you need to measure, remove the measurement section of the pipeline and install it on the detection The device is used for detection at this part. Usually, the standard device in the detection device needs to be manually inserted into the verification position in the pipeline to be tested through a standard device delivery pipe on the detection device, and the standard device is manually inserted into the standard device delivery pipe. When using it, it is unavoidable that hand shaking will occur, so that the bottom probe of the standard is attached to the inner wall of the ...

[0002] In today's pipeline industry, if you want to measure the pressure of the liquid in the pipeline, you usually reserve a measurement section of the pipeline in the required measurement section of the pipeline when installing the pipeline. The device is used for detection at this part. Usually, the standard device in the detection device needs to be manually inserted into the verification position in the pipeline to be tested through a standard device delivery pipe on the detection device, and the standard device is manually inserted into the standard device delivery pipe. When using this method, it is inevitable that hand shaking will occur, so that the bottom probe of the standard device is attached to the inner wall of the standard device delivery pipe, or the relative shaking between the bottom probe of the standard device and the water flow in the pipeline to be tested will affect the measurement accuracy

[0003] At present, in metrological verification activities or experiments, personnel have relatively high requirements for experimental results, but the current detection devices on the market, the placement of standard devices under human operation will cause many irregular problems, resulting in inaccurate measurements or parameters. Inconsistency with the actual value and other issues
