Control circuit of heater control valve

Abstract

A control circuit of a heater control valve comprises a motor (M1) used for controlling on / off of switches, a microprocessor (IC) used for receiving signals and driving the motor (M1) to rotate and a super capacitor (E1) which stores electric energy and provides the electric energy for the motor (M1) after power-down. The control circuit employs the super capacitor instead of common batteries and can freely switch on and switch off the heater valve and set temperature, thereby reducing cost and operating frequency, saving plenty of energy, lowering use cost of users and enjoying high popularization value.

Description

technical field [0001] The invention relates to a control circuit of a heating control valve, which can be applied to a household heating metering system of a new building, or an existing building heating household metering and energy-saving renovation, and is particularly a matching device for a heating intelligent energy-saving metering device. Background technique [0002] my country is a big energy-consuming country, and building energy consumption is a large energy-consuming household in society. Heating energy consumption in northern my country accounts for 25% of local social energy consumption, and heating energy conservation is urgent. my country has taken some measures in terms of heating and energy saving, such as adopting centralized heating and installing heat meters for each household, which has reduced some waste. [0003] However, there are still many problems. Because the traditional heating fee is charged according to the area, users have no enthusiasm for ...

AI Technical Summary

Problems solved by technology

Its control valve control circuit uses mains electricity without batteries, and the closing of the valve relies on large capacitor discharge, which solves the problem of short power supply life of heat metering devices that has plagued our country for many years
