Description

Coldplate weld joint air-tight detection device
Technical field
The invention belongs to air-leakage test technical fields, and in particular to a kind of coldplate weld joint air-tight detection device.
Background technique
Weld leakage is one of frequently problem in engineering, all to be related to the system or zero of liquid (either gas) All there may be leakages for component such as vacuum system, pneumatic system, hydraulic system etc..These systems or components are proposed in engineering Certain air-tightness requirement, and carry out stringent airtight test.Immersion detection method is the main side of air-tightness detection method One of method, it is to be immersed in the water system under test (SUT) or components, then gives its inflation, and whether range estimation has leaked gas with bubble Form evolution, this method is easy to operate, can more intuitively reflect the leakage situation of components, therefore detection efficiency is higher, Testing cost is relatively low.
Cooling water passage structure is complicated inside coldplate on radar installations, and structure size is smaller, and currently available technology can not By casting and being machined monolithic molding, cooling duct can only be processed respectively by way of taking coldplate and dividing half up and down Shape, then by upper and lower two half part, for weld seam at an entirety, the premise of weld seam is to must assure that weldering by welding again The coldplate entirety air-tightness of seam is good, and there can be no the case where gas leakage and infiltration to occur.It is detected in previous weld joint air-tight During test, due to lacking coldplate weld joint air-tight auxiliary detection device, for the compactness for guaranteeing contact, two behaviour are needed Make worker and cooperate detection, air tightness detection apparatus gas transmission nozzle is directed at coldplate cooling duct entrance by a people, and another person then adjusts It saves detection gas pressure and checks weld joint air-tight implementations, generally the conventional detection devices efficiency to coldplate on radar installations Lowly, detection effect is relatively poor, and cost of labor is higher.
Summary of the invention
The present invention provides a kind of coldplate weld joint air-tight detection device, solves radar coldplate weld joint air-tight detection side Face is without mature detection device, the problem of can not carrying out efficient detection to coldplate.
In order to solve the above technical problems, the present invention provides a kind of coldplate weld joint air-tight detection device, feature It is: including posting 1, fastening screw 4, clamping steel plate 3, rubber slab 2, gas pipeline 5 and cap nut 6;The posting 1 Size match with coldplate specification, upper surface be equipped with threaded hole corresponding with multiple fastening screws;Rubber slab 2 and clamping steel 3 size of plate is identical and is bonded together, and is partially equipped with venthole in its center, and rubber slab 2 plays elastic packing and gas transmission Effect;5 lower end of gas pipeline passes through the top of posting 1 and is fixed as one with clamping steel plate 3, the other end of gas pipeline 5 with outside Nut 6 is covered to cooperate;Rubber slab 2 with the air inlet of coldplate for docking;Fastening screw 4 passes through posting and clamping steel plate connects It connects, for making rubber slab 2 and clamping steel plate 3 compress coldplate.
The utility model has the advantages that the present invention can meet different size coldplate neatly according to the size Design Orientation frame of coldplate Weld joint air-tight detection;Structure is simple, easy processing manufacture, easy to operate, shortens the time of airtight detection, significantly subtracts The workload and work difficulty when the detection of coldplate weld joint air-tight are lacked;Detection efficiently, greatly facilitates cooling plate welding seams gas The detection of close property.
