Rheid leakage testing device

Abstract

The invention relates to a rheid leakage testing device and is characterized by comprising a case, a test-piece lock mechanism and an air-pressure balancing and testing system; the front panel of the case is provided with a power switch, a manual valve for selecting, an aeration timer and a test control element; the test-piece fastening mechanism comprises at least two groups of lock sleeve, cone plug, aeration cone tube, lock cylinder and electromagnetic valve; the air-pressure balancing and testing system comprises an observation tube arranged on the case, an air source pressure regulating valve arranged on one side of the case, a standard air bottle in the case, an air bag aerating tube communicated with the standard air bottle and the observation tube, and a test-side aerating tube connected with the observation tube. The invention has the advantages that whether the test-piece has leakage is tested by observing the change of air pressure inside the standard air bottle and the test-piece and whether bubbles are generated in the water in the observation tube, the automation degree is high, the testing operation is simple and quick, the test precision is reliable, the testing quality of the test-piece is improved, the test-piece is prevented from being contaminated in the testing process, and the product quality is ensured.

Description

technical field [0001] The invention belongs to the technical field of air pressure leak detection, in particular to a software leak detection device. Background technique [0002] At present, all kinds of pipelines used in clinical medicine and the connectors connected with the pipelines need to be tested for trachoma or leakage of the connectors themselves before they can be put into use. The traditional detection method is to seal the two ends of the pipeline to be tested, fill one end with a certain pressure of gas, and soak it in water. If bubbles occur, it means that the pipeline is leaking, and then the qualified pipeline is Road and then dry. The disadvantage of this detection method is that it is difficult to observe and detect when the bubbles are small; when soaking in water for air leakage, someone needs to observe whether there are bubbles, which is not only cumbersome to operate, but also time-consuming and inconvenient. Moreover, it is easy to cause the test...

The disadvantage of this detection method is that it is difficult to observe and detect when the bubbles are small; when soaking in water for air leakage, someone needs to observe whether there are bubbles, which is not only cumbersome to operate, but also time-consuming and inconvenient. Moreover, it is easy to pollute the tested part during the testing process, which will affect the quality of the product.
