The utility model is simple in structure, reasonable in design, tightness test is easy to operate, test findings accurately and reliably, can use same set of device to carry out the air-tight test of different size and airtight grade in the time of cost, effectively satisfy the air-tight test of used in nuclear power station different brackets gas-tight door (X, Y, Z), can be widely used in nuclear power station gas-tight door air-tight test.
Description of drawings
Fig. 1 is the structural representation of an embodiment of the utility model.
Fig. 2 is that the A of Fig. 1 is to structural representation.
Embodiment
Embodiment one
Below in conjunction with embodiment the utility model is further described.
The structure of the air tightness tester of the present embodiment nuclear power station gas-tight door as depicted in figs. 1 and 2, test casing 1 is that the Plate Welding of 4mm-10mm forms by thickness, around test casing 1, weld rigidity ribbed stiffener 2, the rigidity ribbed stiffener can be hot rolling joist steel or angle steel, but the strength and stiffness of the structure of warranty test casing.The one side welding U-shaped pressure gauge 3 of test casing 1, U-shaped pressure gauge 3 is to be made of U-shaped glass tube and plastic union pipe, U-shaped glass tube is fixed on the scaleplate with liquid level, one end of its opening passes into test casing 1 by plastic union pipe, whether the other end communicates with atmosphere, calculate the test gas-tight door by manometric reading according to computing formula and meet design requirement in the leakage rate of per hour marking condition.Casing 1 below U-shaped pressure gauge 3 has perforation, and this perforation is punching press perforation 4, and punching press perforation 4 is communicated with air lift pump 6 by adapter 5.Be connected with stop valve 7 control aeration quantitys in the outer end of taking over 5 by screw thread, the other end of stop valve 7 connects plastic tube 8 by punching press and connects air lift pump 6, thereby realizes that air lift pump 6 carries out plenum in test casing 1.Front at test casing 1 is provided with rectangular aperture, before the use, the corresponding test of the specification welding doorframe 9 of the door leaf of testing on demand at the rectangular aperture place, and coat fluid sealant in bearing, further guarantee the sealing of air tightness tester, make the detection data more accurate, pass through the hinged test door leaf 10 of hinge means in a side of test doorframe 9.
During use, at first gas-tight door is tested door leaf 10 and closed, make chamber 1 consist of the casing of a sealing, then use air lift pump 6 to chamber 1 interior plenum, reach the upper limit P of test door leaf 10 design pressures when U-shaped pressure gauge 3 shows test casing 1 internal pressure
