Description

Technical Field

[0001] The utility model relates to the technical field of pipeline pressure detection, in particular to a pressure detector. Background Art

[0002] Plastic pipes are a common type of pipe and pipe fitting in our daily life. They are widely used in sewers, chemical transportation and other fields. They have the advantages of long service life and are not prone to rust. After the pipes are produced, they need to be pressure tested to determine whether the product is qualified.

[0003] At present, when using a pipeline pressure detection device, during the static pressure test of the pipeline, both ends of the pipeline will be blocked, such as a pressure detector disclosed in Chinese patent application No. 202121940716.1. The patent discloses a pressure detector, including a frame, a pull-type movable structure is provided on the frame, a plugging and exhausting component is provided on one end of the pull-type movable structure, and a pressure detection component is provided on the other end of the pull-type movable structure. The pressure detection component and the plugging and exhausting component are symmetrically arranged. The patent relates to the field of plastic pipe processing technology. One end of the pipe to be detected is inserted into the plugging and exhausting component, and the two sides of the pull-type movable structure are controlled to approach each other, and effective blocking of both ends of the pipe is achieved. After the blocking is completed, the pressure detection component is controlled to inject water into the pipe, and the plugging and exhausting component is opened to exhaust. After the gas is completely discharged, the plugging and exhausting component is closed, and then water is continuously injected and pressurized, and the pressurized pressure is detected, thereby realizing rapid detection of the internal pressure index of the pipe. The structure is simple and the reliability is high.

[0004] Although the above patent can insert one end of the pipe to be tested into the sealing exhaust component, and control the two sides of the pulling movable structure to approach each other, and realize effective sealing of both ends of the pipe, and open the sealing exhaust component to exhaust at the same time, after the gas is completely discharged, close the sealing exhaust component, and then continue to inject water to pressurize, and detect the pressurized pressure, but in actual use, the pressure inside the pipeline will increase due to the pressure buildup in the pipeline. If the pipeline is improperly designed or has insufficient bearing capacity, the high pressure will cause the pipeline to rupture or explode. The patent lacks a corresponding protective structure, which will make it easy for the ruptured pipeline debris and water to splash everywhere, which not only pollutes the working environment, but is also more troublesome to clean up, and is also easy to accidentally injure staff, thus posing a safety risk to a certain extent.

[0005] Therefore, it is necessary to modify the pressure detector in the above patent to effectively prevent high pressure from causing pipeline rupture or explosion due to improper pipeline design or insufficient bearing capacity, making it easy for ruptured pipeline debris and water to splash everywhere, which not only pollutes the working environment and is more troublesome to clean up, but also easily injures workers by mistake, thus posing a safety risk to a certain extent.
