Description

Technical Field

[0001] This utility model relates to the field of flame arrester technology, specifically a novel flame arrester. Background Technology

[0002] Flame arresters are primarily used to prevent the spread of flames from flammable gases and liquid vapors. Their working principle typically relies on special materials or structural designs to block fire propagation, such as flame-retardant expanding materials, fire-resistant barriers, or fusible partitions. These flame arresters are usually installed in pipelines transporting flammable gases or on ventilated tanks to prevent the rapid spread of flames to other areas in the event of a leak or explosion, thereby reducing the risk and damage of a fire. Some existing flame arresters are complex in structure, cumbersome to install and maintain, and their flame-retardant performance may decrease in high-temperature environments. Therefore, a new type of flame arrester is needed to address these issues. Utility Model Content

[0003] The purpose of this utility model is to provide a new type of flame arrester, which aims to solve the above-mentioned technical problems. This utility model has a simple overall structure, is resistant to high temperature, has good performance, and ensures safe operation by automatically draining water through a solenoid valve and automatically releasing pressure through a pressure relief valve.
