[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] Please see Figure 1-6 This utility model provides a technical solution: a high-pressure gas insulating container with pressure balancing function, comprising: an insulating tank 1, and a high-pressure regulating device 2. A gas exchange tank 3 is fixedly connected to the outer wall of the high-pressure regulating device 2, and a low-pressure regulating device 6 is fixedly connected to the inner wall of the gas exchange tank 3. A pressure monitoring gauge 4 is fixedly connected to the top of the insulating tank 1, and an alarm device 5 is fixedly connected inside the pressure monitoring gauge 4. Through the high-pressure regulating device 2 and the low-pressure regulating device 6, the internal pressure of the insulating tank 1 can be balanced, making it difficult for the insulating tank 1 to deform or fail to insulate due to excessive or insufficient pressure.
[0028] The high-pressure regulating device 2 includes a first air supply pipe 20, a piston 21 slidably connected to the inner wall of the first air supply pipe 20, a first spring 22 fixedly connected to the outer wall of the piston 21 near the first air supply pipe 20, a first air outlet pipe 23 fixedly connected to the outer wall of the first air supply pipe 20, the side of the first air outlet pipe 23 away from the insulating tank 1 fixedly connected to the air exchange tank 3, the outer wall of the first air supply pipe 20 fixedly connected to the inner wall of the insulating tank 1, and the end of the first spring 22 away from the piston 21 fixedly connected to the inner wall of the first air supply pipe 20. When the internal pressure of the insulating tank 1 is too high, the piston 21 will be pushed open, and high-pressure gas will be introduced into the air exchange tank 3 to relieve the pressure of the insulating tank 1, so that the internal pressure of the insulating tank 1 can be maintained in balance, preventing the pressure from being too high and making it difficult for the insulating tank 1 to be damaged.

When the internal pressure of the insulating tank 1 is low, the valve 61 is opened to introduce high-pressure gas from the air exchange tank 3 into the insulating tank 1, thereby increasing the internal pressure of the insulating tank 1 and preventing the internal pressure of the insulating tank 1 from being too low, making it difficult for insulation failure to occur.

Through the linkage between the pressure monitoring gauge 4 and the alarm device 5, an alarm can be triggered in time when the internal pressure of the insulating tank 1 drops, reminding the staff to make timely adjustments.
[0032] Working principle
[0033] In use, high-pressure gas is introduced and sealed through the gas supply pipes on the back of the insulating tank 1 and the air exchange tank 3, so that the pressure of the insulating tank 1 and the air exchange tank 3 is the same. When the insulating tank 1 is heated by the high temperature of the circuit, the temperature of the insulating tank 1 will also rise, and the internal pressure of the insulating tank 1 will also rise. The high-pressure gas will push the high-pressure regulating device 2 to open, and the high-pressure gas inside the insulating tank 1 will flow into the air exchange tank 3, so that the pressure inside the insulating tank 1 is kept balanced. When the outside temperature drops, the temperature of the insulating tank 1 will also drop, and the internal pressure of the insulating tank 1 will also drop. The pointer 43 inside the pressure monitoring gauge 4 will rotate counterclockwise, which will activate the alarm device 5 to remind the staff that the internal pressure of the insulating tank 1 is too low. After the staff opens the low-pressure regulating device 6, the high-pressure gas inside the air exchange tank 3 will be introduced into the insulating tank 1 to maintain the pressure balance inside the insulating tank 1.
[0034] Since the internal pressure of insulating tank 1 and air exchange tank 3 is the same, when the internal pressure of insulating tank 1 is affected by the high temperature of the circuit, the temperature of insulating tank 1 rises, and the internal pressure of insulating tank 1 will rise accordingly. This increases the density of high-pressure gas inside insulating tank 1. As the density of high-pressure gas increases, the piston 21 inside the first air supply pipe 20 will be pushed by the gas pressure, causing the first spring 22 to be stretched. After the piston 21 is pushed out of the first air supply pipe 20, the high-pressure gas inside insulating tank 1 will enter the first air outlet pipe 23 and enter the air exchange tank 3 through the first air outlet pipe 23. At this time, the internal pressure of insulating tank 1 is reduced. When the internal pressure of insulating tank 1 drops to a level that is insufficient to push the piston 21, the piston 21 will enter the first air supply pipe 20 under the action of the first spring 22, blocking the first air supply pipe 20, maintaining the pressure balance inside insulating tank 1, preventing excessive pressure, and making it difficult for insulating tank 1 to be damaged.
[0035] When the temperature of insulating tank 1 returns to normal, because the temperature of insulating tank 1 had previously increased, some high-pressure gas was sent into the ventilation tank 3. Therefore, after the temperature of insulating tank 1 returns to normal, the volume of high-pressure gas inside it decreases, resulting in a decrease in the internal pressure of insulating tank 1. This causes the pointer 43 to rotate counterclockwise. The baffle 44 prevents the pointer 43 from rotating clockwise, causing the rotating shaft 42 to rotate accordingly. The rotation of the rotating shaft 42 will pull the spring 50 to rotate, causing the rotating rod 51 to rotate, which in turn causes the first gear 52 to rotate. Since the first gear 52 meshes with the second gear 53, the rotation of the first gear 52 will drive the second gear 53 to rotate, causing the hammer 54 to rotate. When the hammer 54 strikes the alarm bell 55, it will sound an alarm, reminding the staff that the internal air pressure of insulating tank 1 is too low. When the hammer 54 strikes the alarm bell 55, it will come into contact with the push plate 57, causing the push plate 57 to press against the first gear 54. When the second spring 56 is compressed, due to the large tooth spacing of the first gear 52, the second spring 56 will quickly extend after the first gear 52 separates from the second gear 53, pushing the push plate 57 to push the hammer 54 towards the other alarm bell 55 on the top of the outer casing 40, causing the hammer 54 to repeatedly strike the alarm bell 55 to alert the staff. When the staff sees through the transparent cover 41 that the pressure shown by the pointer 43 is low, they can turn the valve 61. Since the pressure of the insulating tank 1 has increased previously, some high-pressure gas has been sent into the air exchange tank 3, so the pressure inside the insulating tank 1 will be lower than that of the air exchange tank 3. Turning the valve 61 will send the high-pressure gas inside the air exchange tank 3 into the second air supply pipe 60, and then into the insulating tank 1 through the second air outlet pipe 62, so that the pressure inside the insulating tank 1 increases, maintaining the pressure balance inside the insulating tank 1 and preventing the pressure inside the insulating tank 1 from being too low, making it difficult for the insulation to fail.
