Description

Technical Field

[0001] This utility model relates to the field of locking butterfly valve technology, and in particular to a locking butterfly valve that can prevent misoperation. Background Technology

[0002] In modern industry and various infrastructure constructions, valves are crucial components for controlling fluid transport, and their importance is self-evident. Butterfly valves, with their advantages of simple structure, low flow resistance, and rapid opening and closing, are widely used in many fields, such as petrochemical, water supply and drainage, and HVAC systems. They are responsible for controlling the flow of fluids such as air, water, steam, and corrosive media, and undertake the important tasks of shut-off and throttling. In these complex systems, some scenarios place extremely high demands on the operational safety and accuracy of valves, leading to the development of lockable butterfly valves. Locking butterfly valves, which are ordinary butterfly valves with added locking functions, mainly consist of a valve body, valve seat, butterfly plate, valve stem, and locking mechanism. In some special fields, such as critical safety systems, hazardous media transportation, and residential heating and water supply pipelines requiring standardized management to prevent unauthorized operation, locking butterfly valves play a crucial role in preventing safety accidents or management chaos caused by unauthorized opening and closing. However, early locking methods, such as using warning signs or simple locks, could provide some indication and restriction of operation. To overcome this drawback, current technology employs more complex mechanical locking structures, featuring specially shaped lock cylinders and multi-stage linkage mechanisms. This increases the difficulty of operation and improves the prevention of misoperation, making the locks less susceptible to damage or bypassing. However, these mechanical structures are bulky and complex to install and debug. Furthermore, during long-term use, wear and corrosion of components can lead to jamming and malfunction, causing the locking function to fail and unreliably preventing misoperation.
