Description

Technical Field

[0001] The utility model relates to the technical field of airtight detection and testing, in particular to airtight detection and testing equipment. Background Art

[0002] Airtightness testing equipment is a kind of equipment used to test the air sealing ability of the equipment or parts to be tested. With the continuous development of society and the continuous improvement of production level, people pay more and more attention to the airtightness of parts. Good parts have relatively high airtightness, which can prevent the internal part from exchanging substances with the outside world. Airtightness testing equipment usually puts the object to be tested into water, adds high-pressure air into the object to be tested, and observes whether there are bubbles leaking from the object to be tested. This method requires the object to be tested to contact with the fluid medium, which inevitably leaves the fluid medium outside the object to be tested. Therefore, people have explored a second detection method, which is to place the object to be tested in a closed container and inject high-pressure air into it. The air pressure sensor is used to detect whether the air pressure inside the closed container changes within a certain period of time. If it changes, it means that there is a risk of exchanging substances between the inside of the object to be tested and the outside world. This method will not leave fluid medium outside the object to be tested.

[0003] However, when the existing airtight detection test equipment is detecting the objects to be detected, due to the different volumes of the objects to be detected, when detecting the objects to be detected with larger volumes, only a small amount of air needs to be injected into the detection box of the airtight detection test equipment to make the air pressure in the detection box reach the specified value. When the volume of the objects to be detected is small, a large amount of air needs to be injected into the detection box of the airtight detection test equipment to make the air pressure in the detection box reach the specified value, which seriously wastes the detection time and reduces the detection efficiency. At the same time, the air pump also needs to work for a long time, which increases the detection cost. Therefore, it does not meet the existing needs. In this regard, we propose a valve mouth joint sealing structure. Utility Model Content
