Description

Technical Field

[0001] This utility model relates to the field of laboratory gas supply technology, specifically a centralized laboratory gas supply device. Background Technology

[0002] Centralized gas supply systems, also known as centralized gas supply systems, are an increasingly common gas supply method. They mainly consist of a gas source, switching devices, pressure regulating devices, end-user gas points, and monitoring and alarm systems. In short, a centralized gas supply system delivers gas from a central gas storage facility to various decentralized end-user gas points via pipelines after switching and pressure regulation. This is useful in laboratories where various analytical instruments are required for different experiments.

[0003] Some instruments require high-purity gases. The traditional method is to place gas cylinders directly next to the instruments and connect them to the instruments with hoses for gas supply. This method of gas supply is unsafe and has been gradually replaced by centralized gas supply systems. However, traditional centralized gas supply systems have many problems. They cannot prevent gas from flowing back into the gas cylinders, which can easily contaminate the gas inside the cylinders. They also cannot be quickly disassembled and assembled, and are inconvenient for testing and maintenance. Therefore, there is an urgent need to propose a centralized gas supply device for laboratories. Utility Model Content
