Description

Technical Field

[0001] The utility model relates to the technical field of leakage prevention detection of control valves, in particular to a leakage prevention detection device for control valves. Background Technique

[0002] Control valves play a crucial role in industrial automation. Usually, by controlling parameters such as the flow rate, pressure, and liquid level of the medium, control valves can adjust various indicators in the process flow, making the production process more stable and reliable. Secondly, control valves can promptly adjust abnormal situations in the production process to prevent safety accidents, thus ensuring production safety. A leakage prevention detection device for control valves is a device used to monitor and prevent the leakage of control valves. Its main purpose is to improve the safety and reliability of the system, reduce losses and environmental pollution caused by leakage. The leakage prevention detection device for control valves can effectively prevent leakage accidents in industrial production and ensure production safety.

[0003] When the existing leakage prevention detection device for control valves is actually used, it is not convenient to provide green and sustainable energy for the detection components, and it is difficult to increase the battery life of the leakage prevention detection device for control valves.

[0004] After searching for existing patents: A leakage prevention detection device for a control valve of a municipal road water supply and drainage inspection well (publication number: CN210154754U), including a main valve body and pipelines connected to both sides of the main valve body. Control valves are provided on both sides of the main valve body. The pipelines between the two control valves are connected through flanges. The heights of the two exposed wires are different and are insulated with paraffin. The power supply and the buzzer adopt waterproof models. The volume of the quicklime solid is larger than the volume of the water collecting tank. In the utility model, due to the sliding connection between the slider and the card slot, the vertical limit of the two clamping plates is realized. Also, due to the connection between the water collecting tank and the quicklime solid, the reaction between water and quicklime releases heat to melt the paraffin to connect the buzzer. At the same time, due to the coincidence of the upper end surface of the floating block and the upper end surface of the arc-shaped shell, the control of the water level inside the lower shell is realized.

[0005] Although the above patent realizes the reaction between water and quicklime to release heat to melt the paraffin to connect the buzzer, and at the same time, due to the coincidence of the upper end surface of the floating block and the upper end surface of the arc-shaped shell, the control of the water level inside the lower shell is realized, it is not convenient to quickly and conveniently disassemble and assemble the leakage prevention detection device.
