Description

Technical Field

[0001] This utility model relates to the field of gas ball valves, and in particular to fireproof and self-cleaning gas ball valves. Background Technology

[0002] Gas ball valves are key control components in gas transmission systems. They are valves that open and close by rotating a ball 90° around the axis of the valve stem. When the ball rotates 90° and the channel is perpendicular to the pipeline axis, the gas flow is cut off, completing the closing operation. Gas ball valves have advantages such as low fluid resistance, rapid opening and closing, and good sealing performance. They are widely used in urban gas transmission and distribution networks, industrial gas application scenarios, and household gas appliance connections.

[0003] However, current gas ball valves are unable to detect gas leaks at the connection between the ball valve and the pipeline. Gas is flammable and explosive. Once a large leak occurs, it mixes with air to form a combustible mixture. If it comes into contact with an open flame, electric spark, or other ignition source, it can easily cause a combustion or even an explosion. Due to the lack of a reliable leak detection structure, potential gas leak points cannot be detected in time, and the ideal monitoring and fire prevention pretreatment effect cannot be achieved. Therefore, we propose a fireproof self-cleaning gas ball valve to solve the above problems. Utility Model Content

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This device uses a gas sensor mounted on a monitoring plate to monitor the concentration of gas in the air in real time. The collected data is then transmitted to a data processor for analysis, improving the accuracy and timeliness of gas leak detection. In the event of a gas leak, a flashing indicator light and a voice broadcast alert the surrounding personnel. The device can also send alarm information to mobile terminals and system terminals via a wireless communication module, facilitating timely action by relevant personnel and effectively reducing the probability of fire accidents, thus achieving a pre-treatment fire prevention effect.
