Description

Technical Field

[0001] This utility model relates to the field of duct technology, specifically to a high-pressure lightweight duct device. Background Technology

[0002] Air ducts are pipeline devices used to transport gases. They are core components of ventilation, air conditioning, exhaust, and gas supply systems, and are widely used in building ventilation, industrial production, underground mines, and tunnel construction. The main function of air ducts is to achieve efficient gas transport. At the same time, they must have good pressure resistance and sealing performance during operation to ensure the stability and safety of the system. Especially in high-pressure environments, the performance requirements for air ducts are even more stringent.

[0003] Traditional air ducts are typically made of galvanized iron, stainless steel, or plastic. While these materials can meet basic usage requirements under low pressure and normal operating conditions, they are prone to deformation or leakage under high pressure, making it difficult to guarantee the stability and efficiency of gas delivery. To improve pressure resistance, the wall thickness of the air duct is usually increased. However, directly thickening pure metal or pure plastic air ducts would significantly increase their weight, thereby increasing the difficulty of transportation and installation.

[0004] In terms of duct connection methods, traditional ducts are usually connected and locked together with multiple bolts and nuts to ensure the stability and sealing of the connection. However, this mechanical connection method has the problems of cumbersome steps and long time, especially in confined spaces or environments that require frequent installation and disassembly, making construction difficult. In view of this, we propose a high-pressure lightweight duct device. Utility Model Content
