Abstract

The invention discloses a transmission matching device suitable for a flow equalizing pore plate type adjusting baffle, and relates to a transmission matching device of a baffle. The device aims to solve the problems that the follow-up flow field of a baffle with a traditional louver structure is not uniform, the distribution area at the baffle cannot be flexibly converted, and the flow cannot bewell adjusted, the transmission matching device comprises a frame and a plurality of pore plates, the pore plates are vertically installed in the frame side by side, the transmission matching device suitable for the flow equalizing pore plate type adjusting baffle further comprises a transmission assembly and two limiting pulley assemblies, and the two limiting pulley assemblies are symmetricallyinstalled at the two ends of the frame; the two ends of each pore plate are connected with the two limiting pulley assemblies respectively, the transmission assembly is installed at one end of the frame, and the conveying assembly is connected with the ends of the pore plates. The device belongs to the technical field of industrial automation process control.

Description

technical field [0001] The invention relates to a transmission matching device of a baffle, in particular to a transmission matching device suitable for an equalizing orifice type regulating baffle, and belongs to the technical field of industrial automation process control. Background technique [0002] The orifice-type regulating baffle is a new type of regulating device that can be applied to all pipelines. It uses several groups of orifice plates instead of the blades of the baffle as the regulating element, and uses different combinations of orifice plates instead of the rotation of the baffle blades as the means of adjustment. , not only will not cause turbulence to the downstream medium flow field, but also have an obvious flow equalization effect on the distribution of the pipeline flow field, especially suitable for the outlet of the supply and induced draft fan, so that the velocity distribution of the baffle and its downstream medium is even. [0003] The working ...
