The auxiliary alarm component 2 is arranged on the outer surface of the gas cut-off valve body 1, and the auxiliary connection component 3 is installed at one end of the second gas pipeline 5. The arranged auxiliary alarm component 2 can protect the interface of the gas cut-off valve body 1 and can also perform auxiliary alarm, making its overall safety performance better. At the same time, the arranged auxiliary connection component 3 can connect pipelines at different angles, making its overall installation more convenient.

[0023] As Figure 4As shown in the figure, the auxiliary alarm component 2 includes a first gas pipeline 4 and a second gas pipeline 5, and a reinforcing sleeve 201 is provided on the outer surface of both. External threads 202 are provided on the outer surfaces of the first gas pipeline 4 and the second gas pipeline 5. One end of the reinforcing sleeve 201 is screwed onto the upper part of the external thread 202. A groove 203 is provided inside the reinforcing sleeve 201. A square sleeve 204 is fixedly installed between the inner and outer walls of the reinforcing sleeve 201. One end of the square sleeve 204 communicates with the inner cavity of the reinforcing sleeve 201. A natural gas filter element 205 is installed inside the square sleeve 204. A gas alarm 206 is fixedly installed at the port of the square sleeve 204. Threads 207 are provided on the outer surface of the gas cut-off valve body 1. The inner wall of the reinforcing sleeve 201 is screwed onto the threads 207. The user screws the first gas pipeline 4 onto both ends of the gas cut-off valve body 1.

[0025] When the utility model is in use, when a user installs the gas cut-off valve body 1, by screwing the first gas pipeline 4 onto both ends of the gas cut-off valve body 1, and at the same time screwing the reinforcement sleeve 201 onto the thread 207 in a threaded manner to seal and protect the gas interface. The provided reinforcement sleeve 201 can reinforce and protect the interface, thus alleviating the problem that the interface is prone to looseness after long-term use, resulting in natural gas leakage and other problems. After the leakage occurs, the natural gas is diverted through the installed square sleeve 204, and the gas flows through the natural gas filter element 205 for filtration to reduce the damage caused by the gas to the human body. At the same time, the provided gas alarm 206 immediately gives an alarm after detecting the gas to remind the user of gas leakage. Through the dual reminder function, its safety is better, thus avoiding the problem that the user is at risk of use due to the inability of the gas valve to give an alarm after power failure.
