Description
Technical field
The utility model relates to a kind of Leakage Test device, is specifically related to a kind of Leakage Test device for flange assembly.
Background technology
Along with the continuous progress of science and technology, people require more and more higher to the impermeability of some machineries and equipments, and flange assembly is one of them.When flange and end cap are assembled into flange assembly, whether the position that the bolt of joint flange and end cap and end cap upper screwed hole are installed leaks gas, whether flange and end cap surface of contact leak gas is the key factor checking flange subassembly product quality.Once flange assembly leaks air, just can there are the quality problems such as damage in the complete machine so installing this flange assembly because of gas leakage, thus product is faced reprocess and the consequence such as to be recalled in market.
For this reason, also method or the device of a variety of guarantee flange assembly sealing property have been there is at present, such as: sealing strip, O-ring seal, fluid sealant, sealant, automatically engagement and welding etc., but sometimes very can not be ensured the sealing of product by these approach.Therefore, the Leakage Test for product just seems particularly important.
There is a kind of method of in-water survey product hermeticity at present, by product by being placed on in-water survey after pressurization, but its operation is cumbersome, and sometimes because of water environment or can think the factors such as interference, make assay occur deviation, therefore testing accuracy cannot ensure.
