双膜储气柜一般由内膜、外膜和气体进出口三部分组成。内膜是与气体接触的部分，通常采用耐腐蚀、弹性好的材料制成，如合成橡胶。外膜则是内膜的保护层，通常由耐撕裂、耐磨损的材料制成，如聚酯纤维。内外膜之间形成密闭腔室，保持气体与外界环境的隔离。

Double membrane gas storage cabinets generally consist of three parts: inner membrane, outer membrane, and gas inlet and outlet. The inner membrane is the part in contact with gas, usually made of corrosion-resistant and elastic materials, such as synthetic rubber. The outer membrane is the protective layer of the inner membrane, usually made of tear resistant and wear-resistant materials, such as polyester fiber. A closed chamber is formed between the inner and outer membranes to maintain gas isolation from the external environment.

在正常工作状态下，双膜储气柜内外膜之间的腔室是一个封闭的空间。当气体进入双膜储气柜时，通过气体进口进入内膜。内膜的弹性使得其能够适应气体的动态变化，同时保持气体与外膜之间的隔离。当气体进一步进入内膜后，内膜会逐渐膨胀，增加了储气柜的容积。这样，储气柜就能够储存更多的气体。

Under normal working conditions, the chamber between the inner and outer membranes of the double membrane gas storage cabinet is a closed space. When gas enters the double membrane gas storage cabinet, it enters the inner membrane through the gas inlet. The elasticity of the inner membrane enables it to adapt to the dynamic changes of gas while maintaining isolation between the gas and the outer membrane. As the gas further enters the inner membrane, it gradually expands, increasing the volume of the gas storage cabinet. In this way, the gas storage cabinet can store more gas.

当气体需要被使用时，通过气体出口从内膜中释放出来。内膜的弹性使得其能够恢复到原始的状态，并将气体推出。同时，外膜的保护作用也有助于内膜的恢复。当气体完全释放后，双膜储气柜的容积会变小，可用空间再次增加。

When gas needs to be used, it is released from the inner membrane through the gas outlet. The elasticity of the inner membrane allows it to return to its original state and expel gas. Meanwhile, the protective effect of the outer membrane also contributes to the recovery of the inner membrane. After the gas is completely released, the volume of the double membrane gas storage tank will decrease and the available space will increase again.

双膜储气柜的工作原理可以简单描述为：通过内外膜的结构，将气体与外界环境分隔开来，从而实现气体的储存和使用。内膜的弹性和外膜的保护作用使得储气柜能够适应气体的动态变化，并保证气体的正常储存和释放。

The working principle of a double membrane gas storage cabinet can be simply described as: by using the structure of the inner and outer membranes, the gas is separated from the external environment, thereby achieving safe storage and use of gas. The elasticity of the inner membrane and the protective effect of the outer membrane enable the gas storage cabinet to adapt to the dynamic changes of gas and ensure the normal storage and release of gas.
