Description

Technical Field

[0001] The present invention relates to the technical field of pipeline airtightness detection equipment, and particularly relates to an automatic detection device for the airtight detection of connecting pipes. Background Art

[0002] Pipeline airtightness detection machines are mainly used to detect whether there are micro holes in the pipeline wall causing air leakage. Since pipelines are usually used to transport various gases (including toxic and polluting gases) or various liquids (including toxic and polluting liquids), the airtightness detection of the pipeline wall is very important. Therefore, the use of pipeline airtightness detection machines is very extensive. However, at present, for the detection of pipeline airtightness, it is mainly carried out by filling high-pressure gas in the pipeline and then immersing the pipeline in water or foaming agent for detection.

[0003] The existing pipeline airtightness detection equipment has the following problems: 1. The existing pipeline airtightness detection equipment realizes airtightness detection by injecting gas into the connecting pipe. Since it is difficult to complete airtightness detection if the connecting pipe is not placed in water when gas is injected into the connecting pipe. 2. When the detection of the connecting pipe is completed, it is necessary to manually take out the connecting pipe from the detection box, thereby reducing the use efficiency. 3. When the connecting pipe is being detected, it is necessary to manually place the connecting pipe in water. Since the connecting pipe is filled with gas, its density is lower than that of water, so it takes a lot of effort to immerse the connecting pipe in water. Therefore, we propose an automatic detection device for the airtight detection of connecting pipes. Summary of the Invention

[0035] It should be noted that the present invention is an automatic detection device for airtight detection of connecting pipes. By providing the support plate 9 and the first hydraulic cylinder 8, when in use, when the connecting pipe needs to be subjected to airtightness detection, first, gas is injected into the connecting pipe, and then the third hydraulic cylinder 91 drives the second push rod 93 to connect the sealing cover 94 to the connecting pipe, so that the connecting pipe forms a closed state. At the same time, it is necessary to drive the first push rod 81 and the connecting plate 82 through the first hydraulic cylinder 8, so that the connecting pipe can easily invade the water, thereby reducing the labor consumption.

Then the third hydraulic cylinder 91 drives the second push rod 93 to seal the connecting pipe with the sealing cover 94, so that the connecting pipe reaches a sealed state. Then, with the double assistance of water and gas, it can quickly detect whether the airtightness of the connecting pipe is intact. When the connecting pipe filled with gas invades the water, for the bad connecting pipe that invades the water, the gas will leak from the bad connecting pipe, thus forming bubbles. However, for the good connecting pipe that invades the water, the gas will not leak, so as to distinguish whether the connecting pipe is good or bad. The baffle 122 is driven to move to the right by the regulating rod 124 and the slider 123, so that the connecting pipe can fall from the support plate 12 into the detection box 7.
