    Abstract: The invention relates to a pressure vessel (10) for gases, in particular helium, which is characterized in that the pressure vessel has an outer casing having pressure resistance up to an internal gas pressure of at least 10 bar, in that the outer casing of the pressure vessel has at least one highly diffusion-resistant barrier layer having a leak rate for helium at an internal gas pressure of 10 bar and room temperature of preferably less than 10−2 mbar·l/s, and in that the vessel has an accommodating volume for gas at atmospheric pressure of at least 25 liters. The outer casing of the pressure vessel can comprise at least one barrier layer made of a flexible polymer film having a high barrier function or ultra barrier function or at least one highly gas-tight flexible barrier layer made of EVOH. The vessel can be bag-like or, in particular at higher pressures, inherently rigid. High-strength plastics made of fiber granular materials, for example, can be used to produce the layer, which guarantees the high pressure resistance. Seams (12) can be provided, for example in the lateral edge areas, in order to reinforce and stabilize the pressure vessel. The pressure vessel (10) according to the invention can have a ball valve (11) as a closing element in order to remove the gas.

    Abstract translation: 本发明涉及一种用于气体,特别是氦气的压力容器(10),其特征在于,所述压力容器具有外壳,所述外壳的耐压力至多达10巴的内部气体压力,其中外壳 压力容器具有在内部气体压力为10巴且室温优选小于10-2毫巴·l /秒时具有氦泄漏率的至少一个高度耐扩散阻挡层,并且该容器具有 在大气压至少25升的气体中容纳容量。 压力容器的外壳可以包括由具有高屏障功能或超屏障功能的柔性聚合物膜制成的至少一个阻挡层或由EVOH制成的至少一个高度气密的柔性阻挡层。 容器可以是袋状的,或者特别是在较高的压力下,固有刚性。 例如,可以使用由纤维颗粒材料制成的高强度塑料来生产该层,这保证了高耐压性。 可以例如在侧边缘区域中提供接缝(12),以便加强和稳定压力容器。 根据本发明的压力容器(10)可以具有球阀(11)作为关闭元件,以便除去气体。
