Gas valve is a common safety device used to control the supply and shutdown of gas. It is usually installed at the entrance of the gas pipeline and can manually or automatically control the flow of gas. The types and functions of gas valves vary, but their common goal is to ensure the safety and reliability of gas supply.
Types of gas valves
The type of gas valve depends on their function and purpose. Here are some common types of gas valves:
1. Manual gas valve: Manual gas valve is the most common type, usually used for household gas supply. They can control the gas flow by rotating the handle or turning the manual switch. Manual gas valves are suitable for low-pressure gas pipelines.
2. Automatic gas valve: The automatic gas valve can control the flow of gas through electrical or pneumatic signals. They are commonly used in industrial and commercial gas pipelines to achieve more precise control and monitoring.
3. Emergency shutdown of gas valve: Emergency shutdown of gas valve can automatically close the gas pipeline to prevent dangerous accidents such as fire and explosion. They are usually integrated with monitoring systems and can automatically trigger when gas leaks or fires are detected
