This invention discloses a gas ball valve with automatic shut-off function for gas leak detection, relating to the field of gas ball valves. Addressing the problems of existing gas ball valves having limited functionality, lacking gas leak detection, failing to provide timely feedback on gas leaks, and exhibiting low safety, this invention proposes the following solution: It includes a ball valve protective tube body, within which a valve ball is disposed. A first valve stem is mounted on the top of the valve ball. A detection frame is mounted on the side of the first valve stem away from the valve ball. A second valve stem is mounted on the side of the detection frame away from the first valve stem. A rotating handle is mounted on the side of the second valve stem away from the detection frame. A threaded rotating rod is mounted inside the valve ball body. This invention features a novel structure, is easy to use, provides thorough gas leak detection with high accuracy and good detection effect, and promptly shuts off the gas ball valve upon gas leak, thus improving the safety of the gas ball valve.

This invention discloses a method and system for detecting internet link quality based on the browser's HTTP protocol, within the field of computer network quality detection technology. The method includes: obtaining the public IP address and geographical location of the target terminal by calling a public IP query interface based on the HTTP protocol; constructing an HTTP request Uniform Resource Locator (URL) containing random path parameters and timestamps; initiating asynchronous TCP connection test requests to multiple pre-configured target nodes using a first object; receiving and storing the response status of each test request; and obtaining latency data for each test request using a timestamp acquisition program. This invention, by constructing an HTTP request with dynamically generated random path parameters, added timestamp query parameters, set request timeout thresholds, and disabled caching mechanisms, probes TCP ports and can monitor latency data through statistical analysis of quality indicator data, effectively improving the testing efficiency of TCP ports and reducing internet usage costs.
