Problems solved by technology
[0004] However, there are defects in this test method. First, if a product with a complex structure is immersed in water, it may carry gas, and the flip position will cause air bubbles; second, if it is a product with high precision, it will cause corrosion and damage. It will affect the accuracy; moreover, the detection process is cumbersome, the cost is high, and the accuracy is low

The invention relates to the technical field of air tightness testing, in particular to an air tightness testing device. The device comprises an oil pressure packaging module, the oil pressure packaging module at least internally comprises two I-shaped steel frames, packaging air cylinders are fixedly connected to the top ends of the two I-shaped steel frames, an air cylinder push plate is fixedlyconnected to the front end of each packaging air cylinder through an air cylinder push rod, a push baffle is fixedly connected to the front end of the air cylinder push plate, a mounting block is fixedly connected to the middle of the push baffle, the mounting block is of a hollow structure, an exhaust pressure measuring valve is fixedly mounted in a hollow inner cavity of the mounting block, a second fixed row plate is fixedly connected to the front end of the mounting block through bolts, a third fixed row plate is fixedly connected to the top of the mounting block through bolts, and a first fixed row plate is fixedly connected to the rear end of the mounting block through bolts. The device is smaller in size, the whole test time is shorter, the detection cost is lower, the detection precision and efficiency are higher, and the device can be compatible with products with different specifications and has high applicability.
Description
technical field [0001] The invention relates to the technical field of air tightness testing, in particular to an air tightness testing device. Background technique [0002] The air tightness test is mainly to detect whether there is gas leakage in the corresponding part of the product. Air tightness testing is mainly used in pressure vessels that will come into contact with fluids and gases during use. With the rapid development of modern science and technology, the production level of human beings is rapidly improving, and the quality of products has attracted more and more attention. Tightness testing has also been gradually applied to the production process of various related products, and has gradually become an indispensable testing process before products leave the factory. [0003] Nowadays, the method of soaking in water is generally used for the air tightness test of products. As the name implies, this method first fills the product to be tested with a certain am...
