Description
Technical Field
The utility model relates to the technical field of valves, in particular to a full-lining ceramic blanking valve.
Background
At present, in industries such as lithium batteries and the like involving powder, a ceramic blanking valve is replacing a traditional metal blanking valve or a blanking valve made of materials such as polyurea and nylon, and the problem that the traditional blanking valve is not wear-resistant is effectively solved.
For example, chinese patent 202220301831.2 provides a full-lining ceramic blanking valve, which comprises a valve body, wherein the left and right ends of the valve body are respectively provided with a motor side end cover and a manual side end cover, the upper and lower ends are provided with an inlet flange and an outlet flange, and a ceramic rotor is arranged in a central cavity. The outside sealing surfaces of the inlet flange and the outlet flange are provided with a flange surface lining in a slotting way, and the flange surface lining is made of ceramic or high polymer materials. Ceramic lining surfaces are arranged on the inner walls of the feed inlet of the inlet flange and the discharge outlet of the outlet flange and the inner wall of the valve body. The end faces of the manual side end cover and the motor side end cover, which face the ceramic rotor, are also provided with ceramic lining surfaces.
However, the structure of the blanking valve still has the following technical defects:

Secondly, the problems of uneven thickness of the adhesive, local bubbles, empty drum caused by expansion of the bubble under the influence of temperature and extrusion of the adhesive are easy to occur between the ceramic lining and the inside of the valve body, unavoidable appearance flaws such as uneven inner holes, color spots and color differences are also caused by glue re-filling, defective products or waste products are caused, and the overall production efficiency is influenced. Again, such a dispersedly attached ceramic liner has seams, and there is a problem that the liner holes in the vertical direction and the liner holes in the horizontal direction are not aligned, resulting in uneven sealing.
And two ends of the rotating shaft are fixedly supported and installed in the left end cover and the right end cover through fixed bearings respectively. Because the clearance between the bearing and the rotating shaft is small, the matching precision is high. When the rotary shaft is required to be disassembled and assembled for maintenance, once the rotary shaft is pulled out of the bearing, the rotary shaft is offset when aligned with the inner hole of the bearing during the assembly and disassembly due to the influence of the gravity of the rotor and the rotary shaft, the inner hole of the bearing is difficult to reset, and the disassembly and inspection difficulty is increased intangibly.
