雙膜儲氣柜一般由內膜、外膜和氣體進出口三部分組成。內膜是與氣體接觸的部分，通常采用耐腐蝕、彈性好的材料制成，如合成橡膠。外膜則是內膜的保護層，通常由耐撕裂、耐磨損的材料制成，如聚酯纖維。內外膜之間形成密閉腔室，保持氣體與外界環境的隔離。

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.

在正常工作狀態下，雙膜儲氣柜內外膜之間的腔室是一個封閉的空間。當氣體進入雙膜儲氣柜時，通過氣體進口進入內膜。內膜的彈性使得其能夠適應氣體的動態變化，同時保持氣體與外膜之間的隔離。當氣體進一步進入內膜后，內膜會逐漸膨脹，增加了儲氣柜的容積。這樣，儲氣柜就能夠儲存更多的氣體。

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.

當氣體需要被使用時，通過氣體出口從內膜中釋放出來。內膜的彈性使得其能夠恢復到原始的狀態，并將氣體推出。同時，外膜的保護作用也有助于內膜的恢復。當氣體完全釋放后，雙膜儲氣柜的容積會變小，可用空間再次增加。

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.

雙膜儲氣柜的工作原理可以簡單描述為：通過內外膜的結構，將氣體與外界環境分隔開來，從而實現氣體的安全儲存和使用。內膜的彈性和外膜的保護作用使得儲氣柜能夠適應氣體的動態變化，并保證氣體的正常儲存和釋放。

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.
