Description

Technical Field

[0001] The utility model relates to the field of detection devices, in particular to a large-size composite material cylinder water pressure airtight tooling. Background Art

[0002] Composite materials, with their advantages of high specific modulus, high specific strength, and good designability, are widely used in engineering and aerospace, including common composite cylinders and pressure vessels. While providing sufficient strength, these composite cylinders must also consider the specific conditions and environments of their application, often requiring the storage of special substances or pressure requirements.

[0003] While there are currently sufficient facilities and resources for hydraulic and airtightness testing of small composite cylinders, there is a shortage of such equipment. This often requires temporary modifications or the costly establishment of dedicated test sites and equipment, which is both costly and time-consuming. Furthermore, due to the large volume of large composite cylinders, the required water injection volume is large, making it impossible to fill them upright like smaller containers. Conventional tooling for water injection ports lacks specialized design and may even be integrated with the pressurization port, resulting in slow water injection and significantly increased testing time. Therefore, a hydraulic and airtightness tooling for large composite cylinders has been proposed to address these issues. Utility Model Content

[0006] Preferably, the plurality of groups of mounting holes are distributed in a ring shape on the saddle seat and the upper bracket, so that the plurality of groups of connecting rods are cylindrical.
