Automatic detection control method for overflow leakage of liquid pipeline

Abstract

The invention belongs to the technical field of fluid overflow leakage detection and relates to an automatic detection control method for overflow leakage of a liquid pipeline. The automatic detection control method comprises the steps that firstly, an automatic liquid pipeline overflow leakage detection control device is installed between a heating radiator and a heating pipeline; heater flow parameters are monitored by a flow sensor in real time and uploaded to a control chip; the control chip is used for operation and processing according to a set command; and when leakage of the heating pipeline is judged, the chip is controlled to control a valve to be closed automatically, and thus the loss of a heater user is reduced. The heater user regulates the heater supply quantity according to heating requirements, the control chip is used for monitoring the temperature, flow and pressure of heating media and parameter information of the flow speed in real time according to the flow sensor and controlling the valve to operate, and the valve can be closed in time when unusual conditions happen; a heating control center can check heating fee according to temperature data recorded and stored by the control chip, and the heating fee can be refunded for overpayment or supplementary payment is demanded for shortage; and the technological process is simple, the theory is scientific and reasonable, the performance is safe and reliable, energy is saved, environmental friendliness is achieved, and the use environment is friendly.

Description

Technical field: [0001] The invention belongs to the technical field of fluid leakage detection, and relates to an automatic detection and control method for liquid pipeline leakage, which monitors heating flow parameters in real time, and can automatically control the closing of a valve when it is judged that a heating pipeline leaks, thereby reducing losses of heating users. Background technique: [0002] Heating refers to a central heating facility. The steam or hot water produced by the boiler is transported to the radiator in the room or car body by the heating pipe, and the heat is released to increase the room temperature, and then flow back to the boiler for reheating and circulation. The heating is divided into Plumbing heating and gas heating, water heating is to use wall-hung boiler or boiler to heat circulating water, and then connect to radiator through pipes, and finally output suitable temperature through radiator to form indoor temperature difference, and fina...

[0002] Heating refers to a central heating facility. The steam or hot water produced by the boiler is transported to the radiator in the room or car body by the heating pipe, and the heat is released to increase the room temperature, and then flow back to the boiler for reheating and circulation. The heating is divided into Plumbing heating and gas heating, water heating is to use wall-hung boiler or boiler to heat circulating water, and then connect to radiator through pipes, and finally output suitable temperature through radiator to form indoor temperature difference, and finally carry out thermal cycle to make the whole indoor temperature rise evenly, while gas Warm is to heat the air. As soon as the cold air comes in, it is heated by the radiator to become hot air. The hot air rises and forms convection with the cold air in the room. The cold air circulates to the heating area and is heated to become hot air. The room or car body is warmed; the advantages of central heating are good heating effect, high resource utilization rate, and low average cost. The main disadvantages are: residents have no right to choose, cannot adjust the temperature, and the heating effect of high-rise residents is relatively poor. The charges are the same, and some households owe fees, but the heating is used as usual, which is unfair; the Chinese patent 201420582125.5 with the application date of October 10, 2014 discloses an intelligent energy-saving wired control method for heating, including signals for receiving, processing Microprocessor for data and control of peripheral equipment, motor for driving the opening and closing of the heating valve, temperature sensor, display method, key module, clock chip, MAX487 communication module and power supply module, and the valve is driven by the microprocessor to drive the motor On the premise of not making major changes to the existing pipelines, the user can freely switch the heating valve according to the needs, grasp the information such as indoor temperature and heating time in real time, and can pay the heating fee by IC card prepayment; the application date A new intelligent energy-saving valve for indoor heating systems disclosed in Chinese patent 201420596980.1 on October 16, 2014 is composed of a valve switch, a pre-storage module, a photosensitive module, a trigger module and a power module, and the valve switch is connected to the pre-storage module , the pre-energy storage module is equipped with a spring spring, the other end of the pre-energy storage module is connected to the photosensitive module, the output end of the photosensitive module is connected to the trigger module, and the trigger module is connected to the power module
