Abstract
The utility model relates to a household electronic coal gas inductive switch. The output end of a coal gas pipeline is connected with cookware; the pipeline is sequentially provided with a manual valve and an electromagnetic valve which is in a disconnecting state; a circuit of the electromagnetic valve is connected with an electromagnetic relay and a gas sensor in series; under the general condition, when the electromagnetic valve is in the disconnecting state, the connection and the disconnection of gas are controlled by the manual valve; and when the gas leaks and the gas sensor detects that the concentration of carbon monoxide is over the upper limit set by the sensor, the circuit of the electromagnetic valve is conducted, and then the electromagnetic valve is absorbed, so that the gas output is stopped, and the safety for gas use is ensured. In the household electronic coal gas inductive switch, the leakage condition of the gas can be detected, the automatic gas cutoff is realized under the condition without persons at home, and the potential safety hazards in the gas use are effectively eliminated. The switch is simple, convenient and safe and is easy to operate.
Description
Technical field
The utility model relates to a kind of switch, especially a kind of domestic electronic coal gas induction switch.
Background technique
At present, the combustion gas in city is mainly based on piped gas, though for daily life has been brought convenience, but because coal gas flammable and contain the toxic gas carbon monoxide exists certain potential safety hazard, sometimes in the process of cooking or heating up water, because people's carelessness, having forgotten and shut gas valve and cause fire or gas poisoning, how realized dying automatically of coal gas under people forget the situation of closing valve, is a problem of needing solution badly.
The model utility content
In order to address the above problem, the utility model proposes a kind of domestic electronic coal gas induction switch, this switch can detect the leakage situation of coal gas, and realize dying automatically under the unmanned at home situation, effectively eliminated the potential safety hazard that exists during coal gas uses, and this switch is simple, convenient, safety, easy operating.
The technological scheme that its technical problem that solves the utility model adopts is: domestic electronic coal gas induction switch comprises solenoid valve, gas transducer and electromagnetic relay; The output terminal of gas pipe line is connected with kitchen range; Order is equipped with manually-operated gate and the solenoid valve that is in off state on the pipeline; Be in series with electromagnetic relay and gas transducer on the circuit of described solenoid valve; Generally speaking, solenoid valve is in off state, with the break-make of manually-operated gate control coal gas; Work as gas leakage, the concentration that gas transducer detects carbon monoxide surpasses going up in limited time of sensor settings, and the circuit of solenoid valve is connected, and makes the solenoid valve adhesive, thereby makes coal gas stop output, has guaranteed the Security that coal gas uses.
Described gas transducer is installed in apart from about 0.2 meter～0.5 meter rice of ceiling board.
The upper limit of concentration of described carbon monoxide is 50ppm.
The beneficial effects of the utility model are: this domestic electronic coal gas induction switch can detect the leakage situation of coal gas, and realize dying automatically under the unmanned at home situation, effectively eliminated the potential safety hazard that exists during coal gas uses, and this switch is simple, convenient, safety, easy operating.
