Technical Field
[0001] The utility model relates to the technical field of gas storage tanks, in particular to a sealed gas storage tank. Background Art
[0002] A gas storage tank is a device used to store and transport gas. Early gas storage tanks were mainly simple steel storage tanks. This method has a simple structure and low cost, but low storage efficiency and certain safety hazards. The liquefied natural gas storage tanks currently used have gas valves that can supply or stop gas to the gas-using device after the gas supply valve is connected to the gas-using device by switching the valve.
[0003] However, the connection between the gas transmission valve and the gas-using device is directly exposed to the environment. During long-term use, the internal sealing plug is prone to aging, resulting in reduced sealing of the connection, which in turn makes natural gas leakage prone. The natural gas in the storage tank will leak directly into the environment, posing a major safety hazard.
[0004] Therefore, it is necessary to invent a sealed gas storage tank to solve the above problems. Utility Model Content

[0007] By adopting the above technical solution, the first connecting shell and the second connecting shell are arranged on the outside of the connection between the first connecting pipe and the second connecting pipe, and the connection between the first connecting pipe and the second connecting pipe is sealed to prevent natural gas from leaking into the external air. At the same time, the monitoring module continuously monitors the interior of the connecting shell to detect gas leakage in time.
[0008] Optionally, the third connecting shell is fixedly connected to the rear end of the second connecting shell, a positioning clamp ring is fixedly connected to the rear end of the third connecting shell, and the sealing ring is fixedly connected to the rear end of the positioning clamp ring.
[0009] Optionally, the sealing groove is provided at the front end of the first connecting shell, and the sealing ring is fixedly engaged with the sealing groove.
[0010] By adopting the above technical solution, the sealing ring is clamped in the sealing groove, thereby improving the sealing performance of the connection between the first connecting shell and the third connecting shell.
[0011] Optionally, a first locking block is slidably connected to the surface of the third connecting shell.
[0012] By adopting the above technical solution, the first locking block slides back and forth on the surface of the third connecting shell, and the positioning clamp ring limits the position of the first locking block.
[0013] Optionally, a thread groove is provided on the surface of the first connecting shell near the front side, and the rear end of the first locking block is threadedly connected to the thread groove.
