Description

Technical Field

[0001] The utility model relates to the technical field of pressure stabilizing tanks, in particular to a sealing mechanism for a hydrogen fluoride gas pressure stabilizing tank. Background Technique

[0002] Hydrogen fluoride is a colorless gas with a pungent odor. Both hydrogen fluoride and its aqueous solution are toxic, which can easily cause bone and tooth deformities. Hydrofluoric acid can be absorbed through the skin by mucous membranes, the respiratory tract, and the gastrointestinal tract, and it is a harmful substance to the human body. Therefore, when storing hydrogen fluoride, the sealing integrity of the pressure stabilizing tank should be maintained at all times to prevent leakage and cause harm to people.

[0003] The existing patent No. CN219809763U discloses a pressure stabilizing tank for compressed air, which relates to the technical field of pressure stabilizing tanks. The pressure stabilizing tank for compressed air includes a protective tank body, a lifting mechanism, and a pressure control mechanism. Connecting rings are fixedly installed on the left and right sides of the protective tank body, and an air outlet pipe is arranged at the top of the protective tank body. The lifting mechanism is arranged on the connecting ring. Through the combined use of the first support rod, the chute, the slider, the second support rod, the limiting hole, the limiting screw, the protective tank body, and the pressure stabilizing tank, the device can freely control the height of the device to a certain extent, and then can more conveniently operate the air inlet and outlet of the device. At the same time, the device can be fixed and supported. Through the setting of the protective tank body, the pressure stabilizing tank can be protected to prevent the internal mechanism of the pressure stabilizing tank from being damaged when colliding. The pressure control mechanism is arranged on the protective tank body and is used for outputting and inputting gas so that the air outlet of each air outlet pipe can be controlled separately.

[0004] The existing technology has the following problems:

[0005] 1. For the existing hydrogen fluoride gas pressure stabilizing tank, its own sealing performance is not particularly ideal, which also leads to the leakage of hydrogen fluoride from the tank body due to poor sealing during the use of the pressure stabilizing tank. Moreover, the boiling point of hydrogen fluoride itself is relatively low, and it is very easy to volatilize into the air, causing harm to the human body, reducing the safety of use, and being inconvenient to promote.

[0006] 2. The existing hydrogen fluoride gas pressure stabilizing tank does not have a cooling function, which also leads to the problem that when the pressure stabilizing tank is used in high-temperature weather, due to the relatively low boiling point of hydrogen fluoride, the internal pressure of the pressure stabilizing tank rises and becomes unstable, reducing the service life of the pressure stabilizing tank and not meeting the use requirements.
