Capillary Fire Valves
A capillary fire valve is a safety device commonly used in heating oil systems to prevent fires and leaks of flammable liquids, such as heating oil. It consists of a capillary tube that is sensitive to changes in temperature. Here’s how it typically works:
1. Temperature Sensing: The capillary tube is positioned usually within the boiler housing where it can detect temperature changes. If the temperature in the area where the capillary tube is located rises significantly, it indicates a potential fire hazard or excessive heat. 2. Valve Actuation: When the capillary tube senses a critical temperature threshold, it triggers the fire valve to act. The valve can be set to close, cutting off the flow of fuel (in this case, heating oil) to the burner or heating system. 3. Fire Prevention: The primary purpose of a capillary fire valve is to prevent the continued flow of flammable fuel in the event of a fire or overheating. By shutting off the fuel supply, it helps prevent the spread of the fire and reduces the risk of further damage. Capillary fire valves are an essential safety component in oil heating systems, especially in situations where there’s a risk of fire due to system malfunctions or overheating. They are designed to provide an automatic response to temperature changes, enhancing the overall safety of the heating system and the property it serves.
