Electronic valve for hot water circulation

Abstract

The invention relates to the technical field of valves, and discloses an electronic valve for hot water circulation, which comprises a flow pipe and a circuit board, a detection assembly is arranged on the flow pipe, and the detection assembly is in contact with fluid in the flow pipe to measure data of the fluid; the circuit board is in electric control connection with a fluid supply system, so that the circuit board receives the fluid data sent by the detection assembly and controls the operation state of the fluid supply system according to the fluid data. The fluid temperature in the flow pipe is detected through the detection assembly, data information is transmitted into the circuit board, the circuit board judges whether the data information exceeds a set safety value or not according to the received data information, and if the data information exceeds the set safety value, the circuit board sends a stop instruction to the fluid supply system; therefore, fluid exceeding the set installation temperature value is prevented from entering the flow pipe, and the problem that hot water in the hot water pipe enters the cold water pipe due to the risk that the hot water enters the cold water pipe when the cold water is used, and scalding is caused is solved.

Description

technical field [0001] The invention relates to the technical field of valves, in particular to an electronic valve for hot water circulation. Background technique [0002] A valve is a device used to control the direction, pressure and flow of a fluid in a fluid system. A valve is a device that makes or stops the medium (liquid, gas, powder) in piping and equipment and can control its flow. Valves can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive media. The valve is a control component in the pipeline fluid conveying system. It is used to change the passage section and the flow direction of the medium. It has the functions of diversion, cut-off, throttling, check, shunt or overflow and pressure relief. [0003] In the hot water supply system, the cold water pipe and the hot water pipe are connected through a three-way valve to realize the blending of cold and hot water, and...
