Description

Technical Field

[0001] The utility model belongs to the technical field of gas storage tanks, in particular to a gas storage tank for storing nitrogen. Background Art

[0002] A nitrogen storage tank is a container specifically designed to store high-pressure nitrogen. Made of high-strength, corrosion-resistant materials, it can withstand the high internal pressure and prevent nitrogen leaks. Nitrogen storage tanks are typically equipped with valves, pressure gauges, safety valves, and other safety devices to ensure safe and controllable nitrogen during storage, transportation, and use. These tanks are widely used in various applications requiring nitrogen as a working medium or protective gas, such as metalworking, food packaging, medical surgery, and scientific research. By storing and releasing nitrogen in nitrogen storage tanks, a stable and reliable nitrogen supply can be conveniently provided to meet the needs of various industrial production and scientific research.

[0003] The publication number is CN210241165U, a horizontal gas storage tank that is easy to transport. The utility model discloses a horizontal gas storage tank that is easy to transport, including a tank body for storing gas, an exhaust valve for ensuring the safe use of the tank body, a tripod for supporting the tank body, and finally an outlet valve for outputting gas. A shaft tube is fixedly installed at the middle position of the front end of the outer surface of the tank body, and a positioning hole is opened at the center line position of the shaft tube. A semi-ring is provided on the periphery of the shaft tube. The horizontal gas storage tank that is easy to transport described in the above patent is fixed by connecting the rotating shaft and the folding shaft to achieve the position fixation of the semi-ring, so that the insertion rod on the semi-ring is vertically fixed to the tank body through the positioning hole, and then the fixing process of the tank body is achieved by the mutual cooperation between the upper dynamic ring and the lower fixed ring at the end of the insertion rod, thereby facilitating the transportation of the gas storage tank, improving the stability of the gas storage tank during transportation, being suitable for different working conditions, and bringing better prospects for use.

[0004] However, during the implementation of the above patent, the gas tank needs to be placed horizontally to lower the center of gravity and improve stability, but it needs to be stood up again when it is transported from the transfer tool to reduce the burden on the workers during transportation. On the other hand, nitrogen is stored under high pressure. If the internal pressure cannot be effectively monitored and regulated, it is very easy for the tank to rupture or even explode due to overpressure, which seriously threatens the safety of people and property. In addition, the impact of external temperature changes on the quality of nitrogen in the tank cannot be ignored. Temperature fluctuations may cause the performance of nitrogen to decline, affecting the subsequent use effect. Utility Model Content
