A kind of novel airtight leak-checking apparatus, including tested container, water tank, water inlet, air charging system, cylinder and test fill It sets, water inlet is set on the water tank wall, the water tank upper surface installs pressing plate, clamp lever and fixture is installed in water tank, Described clamp lever one end connects cylinder by chain lock, and on other end fixation clip, the fixture, which is fixedly mounted on pressing plate, to be connected Air charging system is connect, and has ventilation pipe in fixture, the air charging system air accumulator, two breather valves, air inlet pipeline and air inlet Mouth, the air accumulator and two breather valves are ventilated by air inlet into the fixture being connect with pressing plate after being connected by air inlet pipeline Interior ventilation pipe, the test device include gas chamber, pressure sensor, water level sensor, pressure gauge and safety valve, described Gas chamber is mounted on pressing plate, and gas chamber bottom is communicated with water tank, and the water level sensor is mounted on the bottom of gas chamber sidewall, described Pressure sensor, pressure gauge and safety valve pass sequentially through tracheae and are connected with gas chamber;
Further, camera is installed in trepanning on the water tank wall, and the trepanning inner wall installation glass is convenient for shooting;
Further, the camera be mounted on the corresponding water tank wall of tested container cental axial position on, this position with Tested container is parallel;
Further, gasket is installed on the fixture and tested container contact surface;
Further, the chain lock installs sealing ring with junction of the cylinder on pressing plate, and leak, gas leakage effect is avoided to survey Test result;
The utility model judges whether tested container has hole leakage by detecting the pressure change of a small gas chamber, this As long as the leakage that sample container there are some small will be such that the pressure of small gas chamber changes, the detection essence of whole device is improved in this way Degree.
Description of the drawings
Fig. 1 is the surface structure schematic diagram that the utility model is implemented;
Fig. 2 is the structure A sectional views that the utility model is implemented;
Fig. 3 is the structure B sectional views that the utility model is implemented.
Specific implementation mode
The utility model is described in further detail below in conjunction with the accompanying drawings.
Such as Fig. 1, Fig. 2, shown in Fig. 3, a kind of novel airtight leak-checking apparatus, including tested container 1, water tank 2, water inlet 3, Air charging system 4, cylinder 5 and test device 6, water inlet 3 is arranged on 2 wall of the water tank, and pressing plate is installed in 2 upper surface of water tank 7, the interior installation clamp lever 8 of water tank and fixture 9,8 one end of the clamp lever connect cylinder 5 by chain lock 10, and the other end is fixed On pressing plate 7, the chain lock 10 installs sealing ring 17 with junction of the cylinder 5 on pressing plate 7, avoids leak, gas leakage effect test As a result;The fixture 9 is fixedly mounted on connection air charging system 4 on pressing plate 7, and has ventilation pipe 11 in fixture 9, the fixture 9 With installation gasket 16 on tested container contact surface;The air charging system 4 includes air accumulator 12, two breather valves 13, air inlet Pipeline 14 and air inlet 15, the air accumulator 12 and two breather valves 13 by air inlet pipeline 14 connect after by air inlet 15 Ventilation enters the ventilation pipe 11 in the fixture 9 being connect with pressing plate 7, and the test device 6 includes gas chamber 19, water level sensor 20, pressure sensor 21, pressure gauge 22 and safety valve 23, the gas chamber 19 are mounted on pressing plate 7,19 bottom of gas chamber and water tank 2 communicate, the water level sensor 20 be mounted on 19 side wall of gas chamber bottom, the pressure sensor 21, pressure gauge 22, and Safety valve 23 passes sequentially through tracheae and is connected with gas chamber 19;Camera 24, the trepanning inner wall are installed in trepanning on 2 wall of water tank Glass 25 is installed convenient for shooting;The camera 24 is mounted on the corresponding water tank wall of tested container cental axial position, this position It sets parallel with tested container;Sealing ring 18 is installed at the sealing of pressing plate 7 Yu the water tank;
