The invention discloses an electric adjusting device of a thermal regenerative system, and relates to the technical field of thermal regenerative systems. The electric adjusting device comprises a shell, an automatic plugging mechanism, a flow adjusting mechanism and a pressure adjusting mechanism, wherein the shell is arranged between a first connecting tube and a second connecting tube, the shell communicates with the second connecting tube; a conical opening in butt joint with the first connecting tube is formed in the shell; the automatic plugging mechanism comprises an elastic reset assembly and a circular-truncated-cone-shaped plugging block, and the elastic reset assembly is connected with the circular-truncated-cone-shaped plugging block so that the circular-truncated-cone-shaped plugging block can plug the conical opening under the action of the elastic reset assembly; the flow adjusting mechanism achieves the purpose of adjusting the gas flow by changing the size of a gap between the circular-truncated-cone-shaped plugging block and the conical opening; the pressure adjusting mechanism is connected with the elastic reset assembly to adjust the elastic force of the elastic reset assembly, and the situation that the elastic force becomes weak after the elastic reset assembly is used for a long time is prevented, so that the conical opening can be stably blocked by the circular-truncated-cone-shaped plugging block.
Description
technical field [0001] The invention relates to the technical field of thermal recuperation systems, in particular to an electric regulating device for thermal recuperation systems. Background technique [0002] In the heat supply system of thermal power plants, a thermal recovery system is required. Since the peak heat supply during the day exceeds the heat supply capacity of the unit, the heat supply pressure drops, and the heat supply quality cannot meet the needs of heat users. It can be used when the heat load is low When the air flow rate is reduced, the high additional steam consumption can be reduced to improve the heating capacity of the unit. [0003] However, since the high-intake steam electric valve set on the connecting pipeline is a gate valve, which is a shut-off valve, it cannot remotely control and adjust the air flow according to the needs of use, which will affect the use, and it is not convenient to stop the gas supply in time. Automatic plugging cannot...
