AI Technical Summary
Technical Problem
Conventional valve plates are prone to accumulation of materials, dust and condensation media, resulting in an increase in the valve opening pressure and affecting the safety of the storage tank.
Method used
A structure including a valve stem, a tapered ash-dropping disc and a valve plate is designed. The tapered ash-dropping disc guides materials and dust through its tapered side walls to prevent material accumulation and further improves the guidance effect through the backlash edge.
Benefits of technology
It effectively prevents the weight of the valve disc, maintains the stability of the pressure when the valve is opened, avoids the risk of the valve not being opened in time to relieve pressure, and ensures the safety of the storage tank.

Abstract
The utility model relates to the technical field of valves, in particular to a valve disc structure capable of preventing material accumulation, which comprises a valve rod, a conical ash falling disc and a valve disc, the valve rod is arranged in a round hole in the middle of the valve disc, the valve rod is matched with a positioning round hole in the top end of the conical ash falling disc in an inserted mode, and the diameter of the top end of the conical ash falling disc is smaller than that of the bottom end of the conical ash falling disc. The inner wall of the bottom end of the conical ash falling disc is in contact fit with the edge of the top face of the valve disc, the conical ash falling disc is arranged, materials, dust and media easy to condense and crystallize can be guided through the conical side wall of the conical ash falling disc, the weight of the valve disc can be further prevented from being increased, and when the valve disc needs to be opened in the valve, the pressure for opening the valve disc is kept unchanged. And the safety of the storage tank is not influenced because the valve cannot be timely opened for pressure relief.
