First, the external gas is transported to the interior of the high-pressure metering cabinet body through the suction fan and the top frame. When the internal sealing performance of the high-pressure metering cabinet body is good, the gas will be transported to the interior of the detection tube, thereby squeezing the piston ring to move, and the piston ring will drive the spring body to move. The displacement of the piston ring is limited by the telescopic rod, so that the piston ring will drive the spring body to squeeze the pressure sensor. When the pressure sensor senses the pressure, the pressure sensor will transmit the signal, so that the external detector obtains the signal and obtains the good sealing performance of the high-pressure metering cabinet body. Then, by starting the one-way valve, the gas inside the detection tube is discharged. At the same time, when the internal sealing performance of the high-pressure metering cabinet body is not good, the piston ring will be slightly squeezed, so that the spring body will not resist the pressure sensor, so the detector cannot obtain the signal transmitted by the pressure sensor, so that the detection result can be obtained more accurately, which reflects the practicality of the design.

The sealing detection device for the high-pressure metering cabinet is equipped with a suction fan, a suction pipe, a filter plate, a filter screen, a grip rod, a delivery pipe, a mounting pipe and an air supply hole. When in use, the suction fan is started to draw air into the interior of the suction pipe, and then the impurities in the suction process can be blocked by the design of the filter screen inside the filter plate. At the same time, when there are many impurities accumulated inside the filter screen, the filter screen can be rotated by holding the grip rod, so that the filter screen can be easily cleaned. This design can prevent impurities from entering the interior of the high-pressure metering cabinet body, and then the gas is transported through the delivery pipe and the mounting pipe, and then transported to the interior of the high-pressure metering cabinet body through the air supply holes. The detection efficiency is fast, which reflects the functionality of the design. BRIEF DESCRIPTION OF THE DRAWINGS

The high-pressure metering cabinet body 1, detection tube 2, pressure sensor 4, telescopic rod 7, air release pipe 8 and one-way valve 9 used in this application are all products that can be directly purchased on the market. Their principles and connection methods are all existing technologies well known to those skilled in the art, so they will not be repeated here. It includes a high-pressure metering cabinet body 1, a detection tube 2 is arranged on the right side surface of the high-pressure metering cabinet body 1, an adapter ring 3 is arranged on the inner wall of the detection tube 2, and a pressure sensor 4 is arranged inside the adapter ring 3, a top frame 10 is arranged on the top surface of the high-pressure metering cabinet body 1, a suction fan 11 is arranged on the top surface of the top frame 10, a suction pipe 12 is arranged on the left side of the suction fan 11, a filter plate 13 is arranged on the left side of the suction pipe 12, a filter screen 14 is arranged inside the filter plate 13, a delivery pipe 16 is arranged on the right side surface of the suction fan 11, and a lower surface of the delivery pipe 16 is arranged There is a mounting tube 17, which passes through the top frame 10 and is installed inside the high-pressure metering cabinet body 1. An air delivery hole 18 is opened on the outer surface of the mounting tube 17. The filter screen 14 is threadedly connected to the filter plate 13. A gripping rod 15 is fixedly connected to the left surface of the filter screen 14. By starting the suction fan 11 to draw air into the inside of the suction tube 12, the impurities in the air suction process can be blocked by the design of the filter screen 14 inside the filter plate 13. At the same time, when there are many impurities accumulated inside the filter screen 14, the filter screen 14 can be rotated by holding the gripping rod 15, so as to facilitate the cleaning of the filter screen 14. This design can prevent impurities from entering the inside of the high-pressure metering cabinet body 1, and then the gas is transported through the delivery pipe 16 and the mounting tube 17, and then transported to the inside of the high-pressure metering cabinet body 1 through the air delivery holes 18 respectively, so that the efficiency is faster during detection;
[0025] The piston ring 5 is installed inside the detection tube 2. The right side surface of the piston ring 5 is provided with a spring body 6. The outer surface of the piston ring 5 is provided with a telescopic rod 7. The telescopic rod 7 is provided with two groups. The front surface of the detection tube 2 is provided with a vent pipe 8. The outer surface of the vent pipe 8 is provided with a one-way valve 9. The external gas is transported to the inside of the high-pressure metering cabinet body 1 through the suction fan 11 and the top frame 10. When the internal sealing performance of the high-pressure metering cabinet body 1 is good, the gas will be transported to the inside of the detection tube 2, thereby squeezing the piston ring 5 to move, so that the piston ring 5 will drive the spring body 6 to move, and the piston ring 5 will be pressed by the telescopic rod 7. The displacement is limited, so that the piston ring 5 will drive the spring body 6 to squeeze the pressure sensor 4. When the pressure sensor 4 senses the pressure, the pressure sensor 4 will transmit the signal, so that the external detector obtains the signal, and the sealing performance of the high-pressure metering cabinet body 1 is good. Then, the one-way valve 9 is started to discharge the gas inside the detection tube 2. At the same time, when the internal sealing performance of the high-pressure metering cabinet body 1 is not good, the piston ring 5 will be slightly squeezed, so that the spring body 6 will not contact the pressure sensor 4. Therefore, the detector cannot obtain the signal transmitted by the pressure sensor 4, so that the detection result can be obtained more accurately.
[0026] Working principle: When the staff uses the device, firstly, the device is connected to an external power supply to provide power support for the device. Firstly, the external gas is transported to the interior of the high-pressure metering cabinet body 1 through the suction fan 11 and the top frame 10. When the internal sealing performance of the high-pressure metering cabinet body 1 is good, the gas will be transported to the interior of the detection tube 2, thereby squeezing the piston ring 5 to move, and the piston ring 5 will drive the spring body 6 to move. The displacement of the piston ring 5 is limited by the telescopic rod 7, so that the piston ring 5 will drive the spring body 6 to squeeze the pressure sensor 4. When the pressure sensor 4 senses the pressure, the pressure sensor 4 will transmit the signal, so that the external detector receives the signal and obtains that the sealing performance of the high-pressure metering cabinet body 1 is good. Then, the one-way valve 9 is started to discharge the gas inside the detection tube 2. At the same time, when the internal sealing performance of the high-pressure metering cabinet body 1 is not good, the piston ring 5 will be slightly squeezed, so that the spring body 6 will not contact the pressure sensor 4, so the detector cannot get the signal transmitted by the pressure sensor 4.
[0027] By starting the suction fan 11 to draw air into the suction pipe 12, the filter screen 14 inside the filter plate 13 is designed to block impurities in the suction process. At the same time, when there are a lot of impurities accumulated inside the filter screen 14, the filter screen 14 can be rotated by holding the grip 15, so as to facilitate the cleaning of the filter screen 14. This design can prevent impurities from entering the interior of the high-pressure metering cabinet body 1, and then the gas is transported through the delivery pipe 16 and the installation pipe 17, and then transported to the interior of the high-pressure metering cabinet body 1 through the gas delivery holes 18 respectively. The above is all the working principles of the present utility model.
