Abstract
The present invention relates to a kind of Household electronic coal gas inductive switch, the output terminal of gas piping is connected with kitchen range；Manually-operated gate and the solenoid valve being off sequentially are installed on pipeline；Electromagnetic relay and gas sensor are in series on the circuit of the solenoid valve；Under normal circumstances, solenoid valve is off, with the break-make of manually-operated gate control coal gas；Work as gas leak, when gas sensor detects that the concentration of carbon monoxide is more than the upper limit of sensor settings, the circuit of solenoid valve can connected, is attracted solenoid valve, so as to which coal gas be made to stop output, it ensure that the safety that coal gas uses, the Household electronic coal gas inductive switch can detect the leakage situation of coal gas, and realize automatically shut down the gas piping in the case of nobody at home, effectively eliminate security risk present in coal gas use, and the switch is simply, conveniently, safely, it is easily operated.
Description
Technical field
The present invention relates to a kind of switch, especially a kind of Household electronic coal gas inductive switch.
Background technology
At present, the combustion gas in city is mainly based on piped gas, although bringing convenience for people's daily life,
Due to the combustibility of coal gas and containing toxic gas carbon monoxide, there is some potential safety problemss, are cooking or are heating up water sometimes
During, it due to the carelessness of people, has forgotten and shuts gas valve and cause fire or gas poisoning, how to forget in people
Automatically shutting down the gas piping for coal gas is realized in the case of closing valve, is a urgent problem needed to be solved.
Invention content
To solve the above-mentioned problems, the present invention proposes a kind of Household electronic coal gas inductive switch, which can detect
Go out the leakage situation of coal gas, and realize automatically shut down the gas piping in the case of nobody at home, effectively eliminate present in coal gas use
Security risk, and the switch is simply, conveniently, safely, it is easily operated.
The technical solution adopted by the present invention to solve the technical problems is：Household electronic coal gas inductive switch includes electromagnetism
Valve, gas sensor and electromagnetic relay；The output terminal of gas piping is connected with kitchen range；Manually-operated gate is sequentially installed on pipeline
With the solenoid valve being off；Electromagnetic relay and gas sensor are in series on the circuit of the solenoid valve；General feelings
Under condition, solenoid valve is off, with the break-make of manually-operated gate control coal gas；Work as gas leak, gas sensor detects
When the concentration of carbon monoxide is more than the upper limit of sensor settings, i.e., it can connect the circuit of solenoid valve, be attracted solenoid valve, so as to
Coal gas is made to stop output, ensure that the safety that coal gas uses.
The gas sensor is mounted at about 0.2 meter~0.5 meter away from ceiling.
The upper limit of concentration of the carbon monoxide is 50ppm.
The beneficial effects of the invention are as follows：The Household electronic coal gas inductive switch can detect the leakage situation of coal gas, and
It realizes and automatically shuts down the gas piping in the case of nobody at home, effectively eliminate security risk present in coal gas use, and switch letter
Singly, conveniently, safely, it is easily operated.
Description of the drawings
The invention will be further described with reference to the accompanying drawings and embodiments.
Attached drawing 1 is the example structure block diagram of the Household electronic coal gas inductive switch.
In figure：1st, pipeline, 2, solenoid valve, 3, manually-operated gate, 4, kitchen range, 5, gas sensor, 6, electromagnetic relay.
Specific embodiment
In attached drawing 1, which includes solenoid valve 2, gas sensor 5 and electromagnetic relay
6；The output terminal of gas piping 1 is connected with kitchen range 4；Manually-operated gate 3 is sequentially installed on pipeline 1 and is off
Solenoid valve 2；Electromagnetic relay 6 and gas sensor 5 are in series on the circuit of the solenoid valve 2；Under normal circumstances, solenoid valve
2 are off, and the break-make of coal gas is controlled with manually-operated gate 3；Work as gas leak, gas sensor 5 detects an oxidation
When the concentration of carbon is more than the upper limit of sensor settings, i.e., it can connect the circuit of solenoid valve 2, be attracted solenoid valve 2, so as to make
Coal gas stops output, ensure that the safety that coal gas uses.
The gas sensor 5 is mounted at about 0.2 meter~0.5 meter away from ceiling.
The upper limit of concentration of carbon monoxide that the gas sensor 5 detects is 36ppm.
