摘要:
The invention relates to a tank (10) for storing compressed gas having a pressure of at least 15 Mpa, a casing layer (11) which encloses the hollow space (13) provided for storing the compressed gas, and at least one connection for loading and/or unloading the tank (10). In order to decrease the weight of the tank, the casing layer (11) can be constructed of plastic and/or a fiber material. According the invention, supporting elements (30) which are connected to the casing layer (11) are provided in the hollow space (13) of the tank (10) such that the tank (10) can be constructed in any geometric shape and can especially store gasses under high pressure. The supporting elements (30) can be constructed as filaments which are guided through the corresponding guiding canals (31). As a result, the supporting elements (30) assume the function of a seam. A liner (14) preferably constructed of plastic can be arranged on the inner surface (12) of the casing layer (11) in order to additionally seal the tank (10).
摘要:
The invention relates to a plastic core container (2) which is reinforced with a fibre-plastic composite (1), for storing pressurised liquid and/or gaseous media. Said container (2) comprises one or more connecting parts located in the neck and/or base and/or cylindrical container part. At least one of said connecting parts (3) is configured for receiving a screw-in cylindrical or conical pressure-line feed device, such as for example, a valve or pipe connection. The invention also relates to a method for producing a plastic core container (2) of this type. According to the invention, a cylindrical insert (4) is mounted in the connection shank of the plastic core container (2), said insert having an end collar that envelops or surrounds the end of said connection shank. At least two seals are positioned in such a way that at least one seal lies between the insert and the inner surface of the plastic connecting shank of the plastic core container (2) and at least one additional seal lies between the insert and the pressure-line feed device. This guarantees a tight and permanent impermeability in the vicinity of the connecting parts, even under extreme, fluctuating thermal and operational stresses.
