Description

Technical Field

[0001] The utility model belongs to the technical field of mechanical valves, and in particular relates to a valve hand wheel anti-touch device. Background Art

[0002] A valve is a device used to control the flow of a fluid, usually by opening, closing or adjusting its opening to control the flow, pressure or direction of the fluid. Most valves require frequent operation, inspection and maintenance. Placing the valve in a location that is easy to observe and monitor helps operators check the status, flow and operation of the valve at any time. This is essential to ensure the safe operation of the system and to respond immediately to abnormal situations. In some occasions, such as industrial equipment and large piping systems, space may be limited. Placing the valve directly on the pipeline or equipment can save space and simplify the piping layout, making the system more compact and efficient.

[0003] In an open environment, valves may be accidentally touched or misoperated by people or equipment passing by. Such misoperation may cause the valve to open or close unexpectedly, thus affecting the normal operation of the pipeline system or even causing an accident, especially in industrial and high-pressure pipeline systems, where this situation is particularly serious and may cause personal injury and property loss. In an open environment, valves may be accidentally touched or misoperated by people or equipment passing by. Such misoperation may cause the valve to open or close unexpectedly, thus affecting the normal operation of the pipeline system or even causing an accident.

[0004] In summary, existing valves have the problem of being easily touched by mistake, which may lead to accidents. Utility Model Content
