[0027] Refer to Figures 1-4 is a structural schematic diagram of the present utility model. An audible and visual alarm emergency closing system for harmful gas leakage includes an electric valve 1 and an audible and visual alarm 2. When harmful gas leakage occurs, the audible and visual alarm 2 performs an alarm operation. During the alarm process, the electric valve 1 is controlled to perform an emergency closing operation through a signal control unit. The audible and visual alarm 2 is arranged on the front surface of the electric valve 1. A support member 3 is arranged at the bottom end of the electric valve 1. The support member 3 is used to provide support for the fixing member 4. The fixing member 4 is used to support and install the first conveying pipeline 5. The support member 3 is arranged at the bottom end of the fixing member 4, and the first conveying pipeline 5 is arranged inside the fixing member 4.

[0028] Filter components are arranged on both sides of the first conveying pipeline 5. A connecting pipeline 9 is arranged at the bottom end of the first conveying pipeline 5. A collection component is arranged between the connecting pipelines 9. The collection component is used to collect the leaked harmful gas while the audible and visual alarm 2 is alarming. After collection, it can be filtered by the filter component and then discharged.

[0029] Specifically, the filtering component includes a filter pipe 6. A filter element 7 is arranged inside the filter pipe 6.
