The inner part of the butterfly-shaped storage tank liner 300 is pressurized for the first time before winding, so that the possibility of wrinkling caused by instability of the container due to high winding tension in the winding process is reduced; after the carbon fiber winding is completed, the interior of the butterfly tank liner 300 is pressurized a second time, reducing the possibility of container instability due to the change in the shrinkage strength of the carbon fibers during curing. By adopting a secondary pressurizing mode, the internal pressure of the butterfly-shaped storage tank liner 300 is gradually increased, and the possibility of deformation of the butterfly-shaped storage tank liner 300 caused by excessive pressurizing is reduced.
For example, when the butterfly tank liner 300 has a diameter of 2600mm, a length of 1700mm, a straight section of 40mm, a front-to-rear head ellipsoidal ratio of 0.6, and a wall thickness of 1.5mm, the first prescribed pressure is 0.2MPa, and the second prescribed pressure is 0.5MPa.
The non-mentioned places in the application can be realized by adopting or referring to the prior art.
The foregoing are all preferred embodiments of the present application, and are not intended to limit the scope of the present application in any way, therefore: all equivalent changes in structure, shape and principle of this application should be covered in the protection scope of this application.
