Description

Large-drift-diameter manual butterfly valve handle locking device for fracturing construction

Technical Field

The utility model relates to the field of installation and use of butterfly valves, in particular to a handle locking device of a large-drift-diameter manual butterfly valve for fracturing construction.

Background

In large-scale hydraulic fracturing construction, large-diameter liquid supply pipelines are more in use, and because of large liquid supply discharge capacity and large vibration amplitude of the liquid supply pipelines during fracturing construction, a manual butterfly valve installed on the liquid supply pipelines in series is influenced by long-time large vibration of the pipelines to cause failure of a locking device, so that a valve core is closed by large-discharge liquid impact pushing in the pipelines, and liquid supply interruption is caused to influence normal construction.

In order to overcome the problems, after the large-diameter liquid supply pipeline and the manual butterfly valve are installed, the manual butterfly valve handle is wound, bound and fixed by using steel ropes, iron wires and the like, and the steel ropes and the iron wires are repeatedly bound for many times to achieve the handle limiting effect, so that the operation is complicated. When the manual butterfly valve is required to be closed, the steel rope and the iron wire bound on the handle are required to be removed, the operation is also tedious and time-consuming, and the manual butterfly valve is not suitable for being used for rapidly closing the liquid supply pipeline on site. Meanwhile, the large-drift-diameter liquid supply pipeline frequently shakes for a long time to cause abrasion to steel ropes and iron wires wound and bound on the butterfly valve handle, and potential safety hazards exist, so that the utility model provides the hand-operated butterfly valve handle locking device for the large-drift-diameter fracturing construction.
