[0002] As the global demand for electric vehicles and portable electronic devices increases, the demand for lithium batteries is also growing rapidly. This has led to an increase in the supply demand for key battery raw materials, which has promoted the development of lithium battery recycling technology. The lithium battery recycling industry includes the entire process from the collection, classification, disassembly of waste batteries to the recycling and reuse of materials. In the processing of lithium batteries, since the positive and negative electrodes of some lithium batteries are located on the same side, a short circuit between the positive and negative electrodes will occur during processing, resulting in detonation; a plug valve is generally set on the waste lithium battery recycling line to open and close the recycling line feed port. However, the existing plug valves are generally made of metal, and sparks are easily generated when the plug is moved, which will pose a great safety hazard when processing waste lithium batteries. When the plug valve is opened, the black powder generated by the processing of waste lithium batteries will partially rise to overflow the plug valve, and the black powder is extremely valuable, so it is necessary to recycle it.

[0003] Therefore, in view of the problems existing in the prior art, it is urgently necessary to provide a gate valve suitable for a waste lithium battery recycling line to solve the problems existing in the prior art. Summary of the invention
