Description
Technical field
The utility model relates to a kind of leakage detection apparatus, belongs to by the appearance in leak detection point test fluid to come detecting device impermeability technical field.
Background technology
At present, in the work flow of refrigeration welded articles, need to detect product, to characterize its welding effect.Yet conventional technology adopts the complex way such as some ultrasound waves to detect more, and this detection means is complex operation not only, and the testing environment and the testing cost that need are all higher, is not suitable for the actual detection demand of welded articles.
Have based on this, make the utility model.
The utility model content
The purpose of this utility model is to provide a kind of simple in structure, leakage detection apparatus accurately of hunting leak fast.
For achieving the above object, the technical scheme of employing is as follows:
Leakage detection apparatus comprises frame, and described upper rack is provided with sample stage, the corresponding packoff of connecting source of the gas that is provided with in sample stage top; Frame lower is provided with the leak detection groove, and the leak detection groove passes through air cylinder driven.
For realizing better result of use, further arrange as follows:
Described leak detection groove is transparent cell.
Described packoff is airtight bolt.
Described sample stage top is provided with several major lights, opens major light by control panel, light direct projection leak detection groove, and whether in the leak detection process, can tell more clearly test sample to be checked has bubble to occur.
Described leak detection trench bottom is provided with heating tube.
Weld complete test sample to be checked such as sample plasma bottle or pipe sample cooling after, be placed on the sample stage of the utility model leakage detection apparatus, and at its opening, gas check be installed.Control panel is installed on frame, and control panel is controlled leak detection gas, cylinder, major light etc., by control panel, makes leak detection gas enter test sample to be checked; And by the air cylinder driven groove of hunting leak, leak detection liquid that the leak detection groove is risen in it floods whole test sample to be checked, keeps 30-90 second.If the welding position of test sample to be checked is equipped with bubble, show that there is defective in the welding position of this sample to be hunted leak, this sample to be hunted leak is unacceptable product, on the contrary if overflow without bubble the welding position, this sample to be hunted leak is certified products.
For convenience of observing, several major lights can be set above sample stage, the high light direct projection enters liquid to be measured like this, makes the state on test sample to be checked surface more clear, and the effect of hunting leak is more definite; The heating tube that the leak detection trench bottom arranges can heat the liquid in the leak detection groove, makes fluid temperature increase, and is conducive to leak detection.
The utility model leakage detection apparatus is simple in structure, and is easy to operate, can be used in conjunction with Automaticflame Brazing or stove weldering process, leak detection is fast and accurate, and cost is lower, and leak detection liquid wherein can get final product with common water source, get final product and source of the gas has certain pressure, all can as high pressure gas or pressurized air.
