Description

Technical Field

[0001] The utility model relates to the technical field of container heads, in particular to a double-layer container head. Background Art

[0002] At present, double-layer container heads are a common container sealing structure, usually used in industrial equipment, pressure vessels, storage tanks and other fields. This head structure consists of two layers. The inner layer is responsible for sealing, which can effectively prevent medium leakage and ensure the safety inside the container. The outer layer is a reinforcement layer to improve the overall strength and pressure resistance of the head and ensure the safe operation of the container under high pressure environment.

[0003] A double-layer container head is disclosed in the Chinese utility model patent application disclosure CN 214358042 U. The device is provided with an outer circle of an internal elastic head as a rigid end, so it can be used to install a sealing gasket and a compression spring to maintain deformation, and the middle part is provided as an elastic part, which has the ability to deform. When the head is installed, if the pressure inside the container changes, the elastic part will be directly pressed outward, and the elastic part will deform to play a buffering role. Therefore, the inner and outer double-layer head structure in this device can effectively increase the pressure resistance, but there is no certain sealing device at the welding connection, so the device is not stable to install, and there is no certain support capacity inside.
