Description

Technical Field

[0001] This utility model belongs to the field of gas storage cylinder technology, specifically a leak-proof silane gas storage cylinder. Background Technology

[0002] Silanes are important specialty gases with wide applications in many industrial fields such as semiconductors and photovoltaics. However, silane gas is flammable, explosive, and toxic, which makes its storage and transportation processes pose high safety risks.

[0003] In existing silane gas cylinder technology, valves are typically installed at the outlet to control the inflow and outflow of gas. However, in actual use, these valves may age due to prolonged use or be improperly tightened, leading to leaks at the outlet. Once silane gas leaks, it not only wastes valuable gas resources but also causes serious safety accidents such as fires and explosions. Furthermore, the release of toxic silane gas poses a significant threat to the surrounding environment and human health. In addition, changes in ambient temperature during storage affect the temperature of the gas inside the cylinder. When the ambient temperature is too high, the gas inside the cylinder expands due to heat, increasing pressure, which may exceed the cylinder's tolerance limit, causing the cylinder to explode and resulting in a large-scale silane gas leak.

The gas inlet / outlet pipe is connected to a connecting pipe via a first flange and a second flange. A valve for controlling the gas inlet / outlet is disposed on the connecting pipe. A leak-proof component is disposed on the connecting pipe.

[0007] The leak-proof component includes a sealant storage cylinder, on which a delivery pump is installed, and the delivery pump is connected to a connecting pipe via a delivery pipe.

[0029] In this embodiment, the tank 1 is provided with a handle 17 to facilitate the transport of the tank 1.

[0030] Example 2:

[0031] Based on Embodiment 1, the outer side of the tank 1 is covered with heat insulation cotton 23, which can effectively reduce the heat exchange between the gas storage tank and the external environment, reduce heat loss, thereby maintaining the temperature of the gas inside the tank is stable, reducing the risk of explosion caused by excessive pressure inside the tank 1 due to external factors, which could lead to leakage of toxic silane, harm the environment, and even cause poisoning of personnel.

[0032] In this embodiment, a connecting plate 18 is detachably installed on the tank body 1. A sliding groove 19 is provided on the connecting plate 18. Two symmetrically arranged limiting blocks 20 are slidably connected inside the sliding groove 19. A guide hole 21 is provided on the limiting block 20. By passing the end of the heat insulation cotton 23 through the guide hole 21, the heat insulation cotton 23 is clamped by the two limiting blocks 20 to prevent the heat insulation cotton 23 from falling off.

[0033] In this embodiment, a plurality of compression springs 22 are provided between the two limiting blocks 20, and the plurality of compression springs 22 are arranged at equal intervals to clamp the two limiting blocks 20 together and compress the heat insulation cotton 23, thereby fixing the heat insulation cotton 23 and making the heat insulation cotton 23 adhere to the outer wall of the tank 1.
