[0023] A cabin penetration component air tightness test system comprises a gas tank 2, both ends of the gas tank 2 are provided with open ends, the open ends are divided into a test state and a non-test state, when the open end is in the non-test state, a detachable sealing component is installed on the open end through a connector 5, when the open end is in the test state, a test component is installed on the open end through the connector 5;

[0024] The test assembly includes a sealing ring 6 and an adapter flange 7 assembly. The sealing ring 6 is sleeved between the connecting piece 5 and the gas tank 2. The connecting piece 5 is connected to the adapter flange 7 assembly. The adapter flange 7 assembly is connected to the cabin penetration assembly to be tested. The gas tank 2 is provided with an air inlet valve 201, a pressure gauge air inlet valve 203 and an electronic pressure gauge.

[0025] Before the test, it is necessary to test the air tightness of the gas tank 2. Both ends of the opening are sealed by sealing components. The air inlet valve 201 is connected to the air compressor 1. The air inlet valve 201 and the electric meter air inlet valve 201 are opened. The air compressor 1 supplies air to the gas tank 2. The air pressure value is read by the electronic pressure gauge. After the set air pressure is reached, the air supply is stopped and the test time is waited for. After the test time is reached, the change of the pressure value in the electronic pressure gauge 202 is observed. If it is within the preset range, it means that the air tightness of the gas tank 2 meets the standard. If it is lower than the preset pressure value, it means that the air tightness of the gas tank 2 does not meet the standard. At this time, the air tightness test of the cabin penetration component cannot be carried out.

[0026] When conducting an air tightness test on a cabin penetration component, if only one cabin penetration component is to be tested for air tightness, select one of the opening ends, remove the sealing assembly and replace it with a test assembly, and keep the sealing assembly installed on the other opening end. When conducting an air tightness test on two cabin penetration components, replace the sealing assemblies at both opening ends with test assemblies.

[0027] Before using the air tightness test system for the penetration component, the air tightness of the gas tank 2 is first inspected. After ensuring that the gas tank 2 has no leakage, the air tightness test of the penetration component can be carried out. During the test, the sealing component at the open end that needs to be tested is removed, the experimental component is installed, and the penetration component with test is connected to the adapter flange 7 component. The air inlet valve 201 and the pressure gauge air inlet valve 203 are opened, and air is charged into the gas tank 2 from the air inlet valve 201. The air pressure value is read through the pressure gauge air inlet valve 203. The air supply is stopped after the air pressure reaches the set air pressure for the air tightness test, and the timing is started. After the test time is reached, the pressure value change in the electronic barometer is observed. The air tightness of the cabin penetration component to be tested is judged by the electronic pressure gauge. If the pressure value of the electronic pressure gauge is within the preset range, it means that the air tightness of the cabin penetration component to be tested meets the standard. If the pressure value is less than the preset range, it means that the air tightness of the cabin penetration component to be tested does not meet the standard. In the utility model, the gas tank 2 is provided with two open ends, which can meet the requirements of air tightness test of two cabin penetration components at the same time, thereby improving the test efficiency. Moreover, according to the size of the cabin penetration component, the adapter flange 7 of the corresponding size can be separately set, so as to carry out air tightness test on cabin penetration components of different sizes. The scope of application is wider, which has positive significance for improving the flange sealing level of the cabin penetration component and the quality reliability of the cabin penetration component.

[0028] In the utility model, the sealing assembly includes a sealing gasket 3 and a flange plate 4. The sealing gasket 3 is sleeved between the connecting piece 5 and the gas tank 2 to play a sealing role. The flange plate 4 is connected to the connecting piece 5 to close the open end to facilitate the subsequent air tightness test.

[0029] In the utility model, the connecting member 5 is a bolt. In the utility model, a plurality of connecting seats are provided on the gas tank 2, and threaded holes are provided on the connecting seats. The plurality of connecting seats are arranged at intervals around the open end, and a plurality of assembly holes 701 corresponding to the threaded holes are provided on the flange plate 4. The assembly holes 701 are connected by bolts, and the threaded holes are connected to fix the flange plate 4 to the gas tank 2, and the open end is sealed.

[0030] In the present invention, a plurality of assembly holes 701 are also provided on the adapter flange 7, and the plurality of assembly holes 701 correspond to the plurality of threaded holes one by one, so as to facilitate fixing the adapter flange 7 to the gas tank 2 by bolts.

[0031] In the utility model, the adapter flange 7 includes a potting glue 702, a pressure plate 703, and a threading hole 704. The potting glue 702 is arranged around the threading hole 704. One end of the pressure plate 703 is fixed to the potting glue 702, and the other end forms a free end extending to the threading hole 704. The head of the cabin penetration component to be tested passes through the threading hole 704, and the cabin penetration component to be tested is connected to the gas tank 2. The pressure plate 703 positions the cabin penetration component to be tested at the threading hole 704. When the gas tank 2 supplies gas, the gas enters the cabin penetration component to be tested, and the pressure value is read by the electronic pressure gauge 202 to judge the air tightness of the cabin penetration component to be tested.

[0032] In the utility model, the gas tank 2 also includes an exhaust valve 205 and a safety valve 204. After the gas tank 2 is tested for air tightness, the gas in the gas tank 2 needs to be discharged through the exhaust valve 205. After the cabin penetration component to be tested is installed, the gas is filled in to measure the cabin penetration component. The safety valve 204 is an opening and closing component that is in a normally closed state under the action of external force. When the pressure in the gas tank 2 rises and exceeds a specified value, a special valve is used to prevent the medium pressure in the pipeline or equipment from exceeding a specified value by discharging the medium outside the system, thereby ensuring the safety of the entire test system.

[0033] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
