Intelligent heat distribution device

Abstract

The invention relates to an intelligent heat distribution device which comprises a flow regulating valve and an electric actuator fixedly connected with the flow regulating valve. The electric actuator is used for controlling the opening degree of the flow regulating valve, and comprises a controller, a motor for providing power and electrically connected with the controller, a drive shaft for transmitting the power to the flow regulating valve, a grating positioning device for controlling the opening degree of the flow regulating valve, and a maximum opening degree detection device; the grating positioning device comprises a grating plate, a light-emitting component and a light-sensitive component; the light-emitting component and the light-sensitive component are arranged on two sides ofthe grating plate and are electrically connected with the controller; the maximum opening degree detection device comprises a touch device and a switch; the touch device can rotate along with the drive shaft; the switch is arranged in the electric actuator and is electrically connected with the controller; and when the touch device rotates to a certain position, the touch device can touch the switch, the motor stops rotating at the moment, and the place is the maximum opening degree position of the flow regulating valve.

Description

technical field [0001] The invention relates to the technical field of intelligent control, in particular to the technical field of intelligent control of central heating network balance, in particular to an intelligent heat distribution device. Background technique [0002] As we all know, in winter, the weather in the northern region is colder, and the main means of heating is central heating. For areas with central heating, during the period of central heating, this situation often occurs: the heating temperature difference between buildings is large, or the heating temperature difference between units is large, so that some building users can wear pajamas indoors, Barefoot, while some building users have to wear thicker clothes and cotton slippers indoors. The main reason for the large difference in the heating effect of this kind of community is the unbalanced distribution of heat in the buildings or units of the community. [0003] The balance adjustment of the heati...
