Problems solved by technology
[0003] In order to ensure the sealing requirements of conventional valves, multi-layer packing structures are often designed on the valve shaft. Due to the friction between the valve shaft and the packing, the driving torque of the valve is large, which does not meet the low driving torque requirements of the sequential booster system for high-temperature valves.

The invention provides a baffle valve bearing structure, comprising a left outer split ring, a left inner split ring, a left valve shaft, a right outer split ring, a right inner split ring, a right valve shaft, the left valve shaft and the right valve shaft are fixedly connected with the left and right ends of the valve plate respectively, and are used to fix the valve plate in the valve body; the left valve shaft is installed in the valve body through the left outer split ring and left inner split ring set ; The right valve shaft is installed in the valve body through the nested right outer split ring and right inner split ring. The bearing structure of the baffle valve of the present invention only has the contact between the protruding circular ring cone of the left inner split ring and the concave tapered groove of the left outer split ring, and the protruding circular ring cone of the inner right inner split ring and the right The outer contact with the concave tapered groove of the open ring, so the contact area is small, and the driving torque of the valve is reduced when the valve is opened and closed.
Description
technical field [0001] The invention belongs to the field of electromechanical technology, and in particular relates to a baffle valve bearing structure. Background technique [0002] For engines equipped with a sequential supercharging system, the compressor control valve usually uses a flapper valve, which needs to be able to be opened and closed in accordance with the engine control strategy, flexible in action, and the driving torque is less than 0.5N·M. [0003] In order to ensure the sealing requirements of conventional valves, multi-layer packing structures are often designed on the valve shaft. Due to the friction between the valve shaft and the packing, the driving torque of the valve is large, which does not meet the low driving torque requirements of the sequential booster system for high-temperature valves. Contents of the invention [0004] In view of this, the present invention aims to provide a baffle valve bearing structure, which can not only reliably seal...
