[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0026] This utility model provides a simulated airtightness inspection device. Through the cooperation of the set air supply hose, connecting pipe, air cylinder, air pressure gauge and sealing monitoring component, it can detect whether the air supply joint is leaking in real time when the airtightness of the projectile under test is being tested, so as to ensure the accuracy of the airtightness test and avoid the problem of the joint leakage affecting the airtightness test results.

[0027] Figure 1 , Figure 2 , Figure 3 and Figure 4 The diagram shown is an overall structural schematic of one embodiment of the simulated airtightness inspection device of this utility model. Please refer to [link / reference]. Figure 1 , Figure 2 , Figure 3 and Figure 4 The main structure of this embodiment includes: a sealing device 1 to be tested, a first valve 2 provided on the sealing device 1, and a gas supply hose 3 connected to the first valve 2, a second valve 4 provided on the sealing device 1 to be tested, and a connecting pipe 5 provided on the second valve 4, a threaded sleeve 7 connected to the end of the gas supply hose 3, a barometer 9 connected to the end of the connecting pipe 5, a gas cylinder 6 provided on the side of the sealing device 1 to be tested, and a pipe 10 connected to the gas cylinder 6, a threaded head 8 connected to the end of the pipe 10, and a support frame 11 provided on the bottom surface of the sealing device 1 to be tested;

[0028] In actual use, the user turns on the switch of gas cylinder 6. At this time, the gas in gas cylinder 6 is transmitted to the gas delivery hose 3 through pipe 10 and finally enters the sealed device 1 to be tested. When the value of barometer 9 reaches the predetermined value, gas cylinder 6 and first valve 2 are closed, and the value of barometer 9 is recorded. After maintaining the pressure for 15 minutes, check whether the pressure value of barometer 9 is consistent with the recorded value. In this way, the airtightness can be determined. Support frame 11 supports the sealed device 1 to be tested.

[0029] A sealing monitoring component is used to monitor for gas leaks during the gas delivery process.

[0030] Specifically, the sealing monitoring assembly includes a first annular block 31 fixed to the outer wall of the gas delivery hose 3, a first annular groove 32 formed on the outer surface of the first annular block 31, a second annular block 33 fixed to the outer wall of the pipe 10, and a second annular groove 34 formed on the outer wall of the second annular block 33; the sealing monitoring assembly also includes a first arc-shaped plate 35 disposed above the first annular block 31, a second arc-shaped plate 36 disposed below the first arc-shaped plate 35, a first arc-shaped rubber pad 37 fixed to the inner side of the first arc-shaped plate 35, and a second arc-shaped rubber pad 38 fixed to the inner side of the second arc-shaped plate 36; the first arc-shaped rubber pad 37 and the second arc-shaped rubber pad 38 respectively engage with the first annular groove 32, and the first arc-shaped rubber pad 37 and the second arc-shaped rubber pad 38 are joined together to cover the first annular groove 32; the monitoring assembly also includes a connecting pipe 39 connected to the top surface of the first arc-shaped plate 35; wherein, the connecting pipe 39 is sealed by a rubber plug;

[0031] In practical use, the first arc-shaped plate 35 and the second arc-shaped plate 36 fit together and cover the outer walls of the first annular block 31 and the second annular block 33. They are then locked together by bolts passing through the first arc-shaped plate 35 and the second arc-shaped plate 36. At this time, the first arc-shaped rubber pad 37 and the second arc-shaped rubber pad 38 are inserted into the first annular groove 32 from two directions. Similarly, the second annular groove 34 also has the same rubber pad. In this way, the first arc-shaped plate 35 and the second arc-shaped plate 36 cover the connection position between the threaded sleeve 7 and the threaded head 8. At this time, the user injects liquid water into the first arc-shaped plate 35 through the connecting pipe 39 and then seals the connecting pipe 39 with a rubber stopper. During the airtightness test, if there is air leakage at the joint, air bubbles will be generated. This allows for direct observation of whether the joint is leaking, ensuring the accuracy of the airtightness test.

[0032] Furthermore, it also includes a sealing assembly, which includes a rectangular slot 351 formed on the bottom surface of the first arc-shaped plate 35 and a sealing strip 361 fixed on the top surface of the second arc-shaped plate 36.

[0033] In practical use, the sealing strip 361 is inserted into the rectangular groove 351. This way, when the first arc plate 35 and the second arc plate 36 are joined together and locked by bolts, water is prevented from overflowing through the inside of the arc plate, ensuring the normal use of the sealing monitoring component.

[0034] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
