[0020] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0021] In the drawings, the same reference numerals all refer to the same components.

[0022] Example 1

[0023] Reference Figure 1 The utility model provides an embodiment: a helicopter pipeline joint leakage detection device, including a high-pressure air pipe 1, high-pressure joints 2 are arranged on the surfaces of both ends of the high-pressure air pipe 1, a helicopter pipeline 3 is arranged on the surface of the high-pressure joint 2 at one end of the high-pressure air pipe 1, a plug 4 is arranged on the bottom end surface of the helicopter pipeline 3, a pipeline ball 5 is arranged in the middle of one side surface of the helicopter pipeline 3, an adapter 6 is arranged on the surface of one end of the helicopter pipeline 3, a leak detector 7 is arranged on the surface of one end of the adapter 6, and a guide port 8 is arranged on the surface of one end of the leak detector 7.

[0024] The high-pressure air pipe 1 and the high-pressure joint 2 are fixedly connected. The high-pressure air pipe 1 is a pipe made of a mixture of high-strength rubber layer and metal wire mesh, with a maximum pressure resistance of 14.4Mpa. The high-pressure joint 2 is set in two groups, which are respectively placed at the two ends of the high-pressure air pipe 1, and the high-pressure joints 2 are all stainless steel copper-plated joints.

[0025] The high-pressure air pipe 1 and the helicopter pipeline 3 are connected and fixed by a high-pressure joint 2. The helicopter pipeline 3 is T-shaped. The helicopter pipeline 3 and the plug 4 are threadedly connected. The plug 4 is made of aluminum alloy.

[0026] The helicopter pipeline 3 and the pipeline ball 5 are fixedly connected, and the pipeline ball 5 is a bidirectional movable ball setting, which is placed in the middle of the inner side of the helicopter pipeline 3. The helicopter pipeline 3 and the adapter 6 are spliced ​​and assembled, and the adapter 6 is a stainless steel copper-plated joint setting, which has two settings, namely a male head and a female head.

[0027] The adapter 6 and the leak detector 7 are spliced ​​and assembled, and the leak detector 7 and the diversion port 8 are spliced ​​and assembled. The leak detector 7 includes an impeller, a micro generator and a display screen.

[0028] Specifically, its structure consists of a high-pressure air pipe 1, a high-pressure joint 2, a helicopter pipeline 3, a plug 4, a pipeline ball 5, an adapter 6, a leak detector 7 and a diversion port 8 to form a helicopter pipeline joint leakage detection device. The helicopter pipeline joint leakage detection device is formed by modifying a fuel flow meter, and then installing the joint to be tested on the flow meter inlet joint, connecting the joint to a self-made high-pressure air pipe 1, and connecting the high-pressure air pipe 1 to the required pressure gas source. The value change of the flow meter is observed, and a reading indicates leakage. The high-pressure gas pipe 1 is used to connect the high-pressure gas source and withstand the high-pressure gas. The male or female head of the high-pressure connector 2 can be determined according to the connected end and is used to connect the north side pipeline. The helicopter pipeline 3 contains a two-way movable ball, which can be replaced with other types of helicopter pipelines 3 for detection according to detection requirements. The plug 4 is used to block the air outlet of another pipeline to facilitate the detection of pipeline leakage. The pipeline ball 5 is a sealing ball that comes with the pipeline. When gas enters the pipeline, the pipeline ball 5 is subjected to pressure and automatically moves to the other side to play a sealing role. The adapter 6 is generally configured with two, male heads at both ends, female heads at both ends, or one male head and one female head, which can be determined according to the male and female conditions of the pipeline connector of the helicopter to be tested. One is used to connect the leak detector 7 with the tested helicopter pipeline, and the other is used to connect the high-pressure air pipe 1 with the tested helicopter pipeline. The leak detector 7 is designed according to the principle of a flow meter. The main principle is that there is a small impeller inside. If gas flows through, the impeller will rotate, and the impeller will drive the micro generator. The generator outputs a current signal, which is linearly proportional to the current according to the relay, and then converted into a flow model on the display screen, that is, the flow value is linearly proportional to the gas flow rate. The gas is discharged from the rear end of the leak detector 7 through the guide port 8, and foreign objects can be prevented from entering the leak detector 7, so that the helicopter pipeline joint leakage detection device can accurately sense the gas leakage and have an accurate leakage value, which provides convenience for leakage detection of helicopter precision pipelines.

[0029] Working principle: When in use, connect two high-pressure connectors 2 to the helicopter pipeline 3 under test, connect the adapter 6 at the other end of one high-pressure connector 2 to the leak detector 7, connect the other end connector of the other high-pressure connector 2 to the high-pressure gas pipe 1, connect the high-pressure connector 2 of the high-pressure gas pipe 1 to the high-pressure gas source, turn on the leak detector 7, and the surface of the leak detector 7 is provided with a debugging button. Press calibration to return the reading to zero and turn on the gas source. At this time, the pipeline ball 5 of the helicopter pipeline 3 under test moves to one side of the leak detector 7, observe the reading on the display screen of the leak detector 7, and record the flow value, which is the leakage value of the helicopter pipeline 3. If there is a reading, it means there is a leakage, and maintenance can be carried out in time to ensure the overall working efficiency of the helicopter.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents.
