Embodiment Construction

[0020] Attached below Figure 1-5 The present invention is described in further detail with the specific embodiment:

[0021] The plastic liner wraps the gas cylinder, including the bottle body and the bottle mouth. The bottle mouth includes the metal bottle mouth 1. The metal bottle mouth 1 is equipped with an injection molded part 2. The vertical height of the metal bottle mouth 1 and the injection molded part 2 is the same. The metal bottle mouth 1 is provided with an annular boss 11 on the outer side of the bottom. The upper surface of the annular boss 11 is a downwardly inclined surface. The injection molded part 2 is in the shape of a ring, and the inner shape of the ring matches the outer shape of the metal bottle mouth 1. The top of the boss 11 is provided with an outer edge body 21, the upper surface of the outer edge body 21 is inclined downward, and the thickness of the outer edge body 21 gradually decreases to 3mm-20mm along with the radial outer edge, and the lowe...

Abstract

The invention relates to a plastic liner wound cylinder for liquefied petroleum gas, in particular to a plastic liner wound cylinder and a manufacturing process. The plastic liner wound cylinder comprises a metal bottle opening. An injection molding piece is arranged outside the metal bottle opening. The metal bottle opening and the injection molding piece are identical in vertical height. A circular bump is arranged outside the lower of the metal bottle opening. The upper surface of the circular bump is a downwards-inclined surface. The injection moulding piece is circular. The shape of the inner side of the circle is matched with that of the outer side of the metal bottle opening. The position of the injection molding piece, relative to the circular bump, is provided with an outer edge body. The upper surface of the outer edge body is a downwards-inclined surface. The thickness of the outer edge body is radially and gradually reduced to 3-20mm. An embedded ring is arranged on the lower surface of the outer edge body. Seal rings are arranged on both sides of the embedded ring. The outer side surface below the outer edge body of the injection molding piece is a blow molding plastic liner. A winding layer is arranged above the outer edge body. The winding layer is distributed at the outer side of the plastic liner to fasten the plastic liner and the metal bottle opening.

Description

technical field [0001] The invention relates to a storage bottle for liquefied petroleum, in particular to a gas bottle wrapped with a plastic liner and a manufacturing process thereof. Background technique [0002] Plastic liner wound gas cylinders have broad prospects for replacing traditional metal gas cylinders due to their light weight, high strength, corrosion resistance and other excellent properties. However, due to the limitation of the strength of the plastic itself, the gas outlet of the plastic liner cylinder is usually made of metal materials. Due to the large difference in modulus and thermal expansion rate of the two materials, the joint of the two materials will be damaged when subjected to cyclic loads. Cracks appear due to discontinuous rigidity; under the action of ambient temperature, thermal stress will be generated, and cracks will appear at the joint, resulting in gas cylinder leakage. [0003] The sealing force between the metal bottle mouth of the p...
