Description

Technical Field

[0001] The utility model relates to the technical field of oxygen gate valves, in particular to an oxygen gate valve. Background Art

[0002] An oxygen gate valve is a valve used to control and regulate the flow of oxygen. It is usually designed for use in oxygen systems, such as oxygen delivery lines in industrial applications or medical equipment. The role of an oxygen gate valve is to control the flow of oxygen by opening or closing the valve to ensure that an appropriate supply of oxygen is available when needed, and to be able to effectively close the oxygen passage when it is not needed, ensuring safety and efficiency. These valves are usually required to meet specific safety and standard requirements to prevent oxygen leaks or other potential safety issues.
