Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] The utility model provides Figure 1-3 A nitrogen recovery pressure alarm device is shown, comprising:

[0024] An installation sleeve 1 is installed, and a mounting plate 2 is fixedly connected to the top of the installation sleeve 1. A detection component 3 is arranged between the installation plate 2 and the installation sleeve 1. An alarm 5 is fixedly connected to one side of the installation sleeve 1. When the second conductive ring 35 contacts one of the first conductive rings 34, the alarm 5 is powered on and works, and the model of the alarm 5 is LTE-1101. A barometer 6 is fixedly connected to the bottom of one side of the installation sleeve 1. The barometer 6 can detect the air pressure at the bottom of the inner cavity of the installation sleeve 1, thereby detecting the gas pressure inside the nitrogen recovery pipeline.

[0025] The detection component 3 includes an airbag cover 33, which is fixedly installed at the bottom of the inner cavity of the installation sleeve 1. Two first conductive rings 34 are fixedly installed in the inner cavity of the installation sleeve 1. A second conductive ring 35 is slidably connected between the two first conductive rings 34. A spring 36 is arranged on the top of the airbag cover 33. The second conductive ring 35 is located between the airbag cover 33 and the spring 36. The airbag cover 33 has a certain length. When the air pressure inside the airbag cover 33 changes, the spring 36 can compress or stretch the airbag cover 33 through the connecting plate 37, thereby changing the position of the second conductive ring 35. The air pressure inside the airbag cover 33 is the same as the pressure inside the nitrogen recovery pipeline. When the pressure inside the nitrogen recovery pipeline is not within the safe range, the connecting plate 37 can drive the second conductive ring 35 to contact one of the first conductive rings 34, thereby causing the alarm 5 to sound an alarm. When the pressure inside the nitrogen recovery pipeline is within the safe range, the airbag cover 33 and the spring 36 can give the connecting plate 37 a balancing force, thereby causing the second conductive ring 35 to be between the two first conductive rings 34. The first connecting sleeve 31 and the second connecting sleeve 32 are fixedly connected to the bottom of the mounting plate 2 between the rings 34. The first connecting sleeve 31 is slidably sleeved in the inner cavity of the mounting sleeve 1. The second connecting sleeve 32 is located inside the first connecting sleeve 31.

When the mounting sleeve 1 is installed on the nitrogen recovery pipeline under the action of the flange 7, the bottom of the inner cavity of the mounting sleeve 1 has the same pressure as the inside of the nitrogen recovery pipeline, so that the airbag sleeve 33 The internal pressure is the same as the pressure inside the nitrogen recovery pipeline, so that the airbag cover 33 and the spring 36 give a balancing force to the connecting plate 37, so that the connecting plate 37 drives the second conductive ring 35 to be located between the two first conductive rings 34 through the two fixing blocks 38. When the pressure inside the nitrogen recovery pipeline exceeds the safety range value, the force exerted by the airbag cover 33 and the spring 36 on the connecting plate 37 changes, and then the connecting plate 37 drives the second conductive ring 35 to contact one of the first conductive rings 34, so that the alarm 5 is powered on and an alarm is sounded.

[0027] A threaded hole matching the spring 36 is provided on the top of the mounting plate 2, and the inner cavity of the threaded hole is threadedly sleeved with a limiting end cover 4, and the bottom of the limiting end cover 4 fits with the spring 36. The limiting end cover 4 is rotated to remove the spring 36, and the spring 36 can be taken out of the threaded hole. By replacing the spring 36 with different elastic forces, the position of the airbag cover 33 and the spring 36 when they are in a balanced state with respect to the connecting plate 37 can be changed, and the internal pressure range of the airbag cover 33 can be changed when the second conductive ring 35 contacts the first conductive ring 34, thereby changing the range of its internal pressure detection of the nitrogen recovery pipeline.
