[0002] For nitrogen transport pipeline components that require sealing performance, leakage will cause serious safety hazards. Therefore, before the pipeline leaves the factory, it is often necessary to conduct a closed inspection to test the sealing effect of the parts to detect whether there is any leakage or seepage in the hose to ensure that it can transport nitrogen normally and ensure the normal operation of the device.

DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] Embodiment 1, as Figure 1-4 As shown, a sealing detection device for nitrogen hose can be used to detect the leakage of the nitrogen delivery hose after production. Before use, the detection barrel 1 is filled with water through the water inlet 4, and the two ends of the gas delivery hose body 12 are respectively connected to the air inlet pipe 7 and the sealing measuring tube 10 at the lower end of the air valve 6. The sealing measuring tube 10 is fixedly connected to the connecting seat 8 and the air valve 6 by a threaded rod, and the gas delivery hose body 12 is sealed and connected by a clamping head 11. The top end of the gas delivery hose body 12 is connected to the inside of the clamping head 11, so as to be fixed to the fixed clamping seat 1. 5 is clamped and fixed, and the threaded layer 16 on the inner side of the clamping head 11 strengthens the sealing and fixing effect to ensure that the device will not leak during the detection process. Then, gas is input into the pipeline through the air inlet pipe 7, and the gas is input into the gas hose body 12 through the through hole inside the fixed clamping seat 15. The gas hose body 12 is immersed in the water inside the detection barrel 1. If the pipeline leaks, bubbles will be generated in the water. The measurement is convenient and the result is accurate. The detection barrel 1 is a transparent structure, and the staff can directly observe the detection situation inside the detection barrel 1, making the device more convenient to use.

[0023] Embodiment 2, as Figure 1-4 As shown, a sealing detection device for a nitrogen hose is used. The device uses a pressurizing machine 14 to pressurize and inflate the inside of the air intake pipe 7. The pressure gauge 9 connected to the outside of the air intake pipe 7 can detect the gas pressure intensity. During the detection process, the pressurizing machine 14 can adjust the input gas and pressure according to the detection situation. The air valve 6 at the end of the gas hose body 12 can seal the pipe mouth. The pressurizing machine 14 can keep the air pressure inside the gas hose body 12 at a constant value for a certain period of time, which is beneficial to the detection and makes the measurement process of the device more adjustable, thereby achieving the effect of controllable air pressure in the pipe during the measurement process.

[0024] How it works

[0025] It should be noted that the utility model is a sealing detection device for a nitrogen hose. When in use, the detection barrel 1 is filled with water through the water inlet 4, and the two ends of the gas hose body 12 are respectively connected to the air inlet pipe 7 and the sealing measuring tube 10 at the lower end of the air valve 6. The sealing measuring tube 10 is fixedly connected to the connecting seat 8 and the air valve 6 by a threaded rod, and the gas hose body 12 is sealed and connected by a clamping head 11. The top end of the gas hose body 12 is connected to the inside of the clamping head 11, so as to be clamped and fixed with the fixed card seat 15. The threaded layer 16 on the inner side of the clamping head 11 strengthens the sealing and fixing effect to ensure that the device will not leak during the detection process. Subsequently, gas is input into the pipeline through the air inlet pipe 7, and the gas is output through the through hole inside the fixed card seat 15. Into the gas hose body 12, the gas hose body 12 is immersed in the water inside the detection barrel 1. If the pipeline leaks, bubbles will be generated in the water. The compressor 14 is used to pressurize and inflate the inside of the air inlet pipe 7. The pressure gauge 9 connected to the outside of the air inlet pipe 7 can detect the gas pressure intensity. During the detection process, the compressor 14 can adjust the input gas and pressure according to the detection situation. The air valve 6 at the end of the gas hose body 12 can seal the pipe mouth. With the cooperation of the compressor 14, the air pressure inside the gas hose body 12 can be kept at a constant value for a certain period of time, which is conducive to detection, thereby achieving the effect of controllable air pressure in the pipe during the measurement process. The detection barrel 1 is a transparent structure, and the staff can directly observe the detection situation inside the detection barrel 1.
