Intelligent control system of valve

Abstract

The invention relates to an intelligent control system of a valve, which is suitable for a warming system for residents. The intelligent control system is characterized by comprising a temperature controller and an executer which are connected, wherein the temperature controller comprises a singlechip which is respectively connected with a clock chip module, a liquid crystal display module, a key module, a temperature sensor module and a power supply module; and the executor comprises a motor drive circuit and a direct current motor which are connected, the signal input end of the motor drive circuit is connected with the signal output end of the singlechip, and the power supply end of the motor drive circuit is connected with the power supply module. The intelligent control system has the beneficial effects that the valve is opened automatically by outage, indoor temperature is effectively prevented from being overflow or a pipe is prevented from being frost-split; the valve is controlled to be flexibly opened, impact caused by water current to the pipe is avoided; the valve is rotated once every other a time interval, and is prevented from being corroded; and the valve is automatically opened, closed or rotated according to a power supply condition, an indoor temperature and a set time interval.

Description

technical field [0001] The invention relates to a valve intelligent control system suitable for residential heating systems. Background technique [0002] In recent years, valve control systems have been widely used in shopping malls, office buildings, supermarkets and home heating systems. At present, most valve control systems include two parts: a thermostat and an electric valve (including electric actuators and valves). The indoor thermostat collects the room temperature and compares it with the set temperature value. The output signal controls the electric actuator to perform corresponding actions according to the comparison value. This action drives the valve to open or close, and then the circulating fluid with a certain amount of heat is sent from the pipeline to the heat sink. system, so that the cooling system starts or stops working, and finally achieves the purpose of regulating the indoor temperature. [0003] There is a serious deficiency in the above-mention...

AI Technical Summary

Problems solved by technology

[0003] There are serious deficiencies in the above-mentioned valve control system, which cannot solve the problem of power failure and heating

After the power failure, the valve always maintains the state before the power failure, which often makes the valve closed for a long time, and then the indoor temperature continues to drop, and even the indoor temperature is too low, the water pipe freezes and cracks, etc.
