Description

Technical Field

[0001] The utility model belongs to the technical field of end caps, and more specifically, particularly relates to an anti-deformation end cap. Background Art

[0002] A head refers to a component used to seal the end of a container to isolate the internal and external media, also known as an end cover. The heads of cylindrical containers are generally rotating shells. The shapes of the head surfaces can be divided into convex, conical, flat and combined shapes. A convex head refers to a head with a convex outer surface, such as a hemispherical, elliptical, dish-shaped and spherical head without folded edges. Some gas cylinders use a combined bottom head with the convex surface inward, which can ensure strength and meet the needs of safe use. However, some heads are now used on pressure vessels as the main pressure-bearing components. When the pressure is too high, it is easy to cause the head to deform, and most of the current heads are directly welded on and cannot be disassembled, replaced or repaired. Therefore, a pressure-resistant, anti-deformation and removable head is needed. Utility Model Content
