Intelligent valve and control method thereof

Abstract

The invention provides an intelligent valve and a control method thereof, and belongs to the technical field of valves. The problem of large energy consumption caused by inconvenient valve adjustment of current heating and air conditioning system is solved. The intelligent valve comprises a valve body, a valve rod and a valve element, wherein the inner end of the valve rod is fixedly connected with the valve element, and the outer end of the valve rod stretches out of the valve body and is connected with an actuator which can drive the valve rod to move; the intelligent valve further comprises a controller, a pressure difference detecting unit capable of detecting the pressure difference of the valve body before and after valving, a display and a key unit capable of inputting set flow into the controller or setting valve opening information, wherein the actuator, pressure difference detecting unit, display and key unit are all connected with the controller, and the controller can receive and process the set parameter input by the key unit and the pressure difference value detected by the pressure difference detecting unit, and can transmit a corresponding control signal to control the actuator to drive the valve rod to move. The intelligent valve and the control method thereof have the advantages of convenience to manage and adjust.

Description

technical field [0001] The invention belongs to the technical field of valves, and relates to an intelligent valve and a control method thereof. Background technique [0002] With the development of cities, buildings will surpass industry, transportation and other industries to rank first in social energy consumption, reaching more than 30% to 40%. Building energy conservation will become the focus of energy conservation and consumption reduction. Large-scale public buildings have large total energy consumption, high unit energy consumption, great energy-saving potential, and easy implementation of work. According to research, it is found that large-scale public buildings generally have energy-saving potentials of 10% to 30%. [0003] Among them, the heating and air conditioning system in the building is the part that consumes a lot of energy, and it mainly achieves the purpose of heat energy transmission through the transportation of water flow. During the delivery of the ...

AI Technical Summary

Problems solved by technology

[0004] However, in the current heating and air conditioning systems, the valves are rarely adjusted after setting, even if the user's heating demand or seasonal changes

When adjusting the valve, it is necessary for the management personnel to carry special instruments and equipment to adjust. There are problems such as inflexible flow adjustment, untimely adjustment, resulting in waste of energy, high energy consumption, single adjustment method and inconvenient management.
