Method for judgement by using valve use condition and valve device

Abstract

The invention relates to the field of energy-saving and environment-friendly natural gas heating stoves and household building water circulation, in particular to a method for judgement by using a valve use condition and a valve device. A time sequence control part is further included and can record the time when a cold and hot water terminal valve (11) is opened at the hot water side and conductjudgement; when the time is shorter than three seconds including three seconds, it is judged to be false trigger, and natural gas heating is still not started even if a flow sensor detects flow data in a hot water demand pipeline; and when the time is longer than three seconds, it is judged that hot water is needed, and natural gas heating is started. By the adoption of the technical scheme, compared with the prior art, the method and the valve device have the advantages of being multifunctional, capable of saving energy and water, environment-friendly, safe, capable of protecting a gas stoveand breaking through a plurality of technical link channels, and capable of achieving high intelligence.

Description

technical field [0001] The invention relates to the fields of energy-saving and environment-friendly natural gas heating furnaces and domestic building water circulation, in particular to a method for judging the use of valves and a valve device. Background technique [0002] Gas water heater, also known as gas water heater, refers to a gas appliance that uses gas as fuel to transfer heat to cold water flowing through a heat exchanger through combustion heating to achieve the purpose of preparing hot water. [0003] At present, there are brands such as Haier and Smith on the market. [0004] The defective of prior art is: [0005] 1. Situation 1: When a person opens the valve, sometimes they need cold water, but they open it wrongly, they open the hot water side, and then they quickly turn off the hot water side and turn it to the cold water side. If there is water flowing in the water, the natural gas gas furnace starts immediately, and the fan starts accordingly. Even if...

Problems solved by technology

[0005] 1. Situation 1: When a person opens the valve, sometimes they need cold water, but they open it wrongly, they open the hot water side, and then they quickly turn off the hot water side and turn it to the cold water side. If there is water flowing in the water, the natural gas gas furnace starts immediately, and the fan starts accordingly. Even if it is turned off immediately, the ignition has already been carried out. The gas furnace must ring for a while before it can stop (the minimum safe time for the fan to blow); mainly: 1. Waste of gas ;2. Waste of fans and electricity; 3. Frequent ignition is not good for the machine;

[0006] 2. Situation 2: When people open the valve and need hot water, the water in the original pipe needs to be drained before cold water can come out, so this part of cold water is wasted; it does not meet the needs of water saving at all;

[0007] 3. Situation 3: The community often cuts off water or some units often have insufficient water pressure;

[0008] 4. Situation 4: If the temperature control is not in place, people will be scalded while taking a bath;

[0009] 5. Situation 5: I don’t know about water leakage at home, and I haven’t taken emergency measures;

[0010] 6. Situation 6: Ordinary people don't always pay attention to how long their valves have been used, and once they leak, it will be very serious;

[0011] 7. Situation 7: When people take a bath, they need to adjust the valve to mix hot and cold water to adjust to the temperature that suits them best. The problem that arises in this way is that the water is heated first and then cooled, which belongs to Energy waste, typical non-energy saving and environmental protection

[0012] There are still many shortcomings, which will not be described in detail here, and will be compared and elaborated in the following expressions
