Most of existing gas leakage alarm devices adopt passive measures, after leakage occurs, an indoor alarm gives an alarm to manually cut off or automatically cut off a gas valve after detecting a certain concentration, usually because a family user neglects, under the condition that the gas valve is not closed, no people or gas appliances in a room age and leak gas, the phenomena of failure of the community power failure alarm and the like occur, explosion caused by leakage of a large amount of natural gas is caused, or due to long time when the gas is used, the phenomenon of dry burning and ignition caused by forgetting to shut off the fire or phenomenon of flash explosion caused by accumulation of gas with a certain concentration in the room when the gas alarm gives an alarm is generated.
SUMMERY OF THE UTILITY MODEL
In order to solve the technical problem, the utility model provides a cutting device is prevented leaking by gas becomes prevention in advance by the processing after the fact, when using the gas, according to the gas needs of oneself, the settlement time, time one to self-closing prevents that above-mentioned phenomenon from taking place the leakage that causes, reaches the emergence of effectively stopping the leakage, improves the purpose of using the gas security.
The technical scheme is as follows: the utility model provides a gas is prevented leaking warning cutting device, it includes the table front main valve, gas table and the gas-cooker of tube coupling, characterized by: the gas meter is characterized by further comprising a normally closed electromagnetic valve, a switch timer, a combustible gas alarm and an external power supply, wherein a gas inlet and a gas outlet of the normally closed electromagnetic valve are respectively connected with the gas meter and the gas stove pipeline, the normally closed electromagnetic valve is connected with a plug connector of the switch timer, the switch timer is connected with a plug connector of the combustible gas alarm, and the combustible gas alarm is connected with a lead of the external power supply; the combustible gas alarm comprises a detector provided with a probe and a controller, and the detector is connected with the controller plug.
Furthermore, the switch timer comprises a power indicator light, a manual switch power-on button and a timer, and the timer is connected with the controller plug.
Further, a power-off memory circuit is arranged inside the switch timer.
Has the advantages that: the utility model discloses a through the cooperation of switch timer control normally closed solenoid valve and other subassemblies, can effectively improve the security of using gas, stop the hidden danger of the long-time leakage of gas and take place, specifically speaking has following several big advantages:
1. the gas source is automatically cut off when the timer is switched off after the gas is not forgotten to be turned off.
2. Under the condition that the set time is not up, gas leakage occurs, and the alarm still sends out an alarm signal and a power-off signal to cut off the gas source.
3. Under the condition that the combustible gas alarm main machine has a fault, the switch timer can be independently used to be directly connected to the power supply, and the cooking gas is not delayed when the switch timer is continuously used.
4. The normally closed electromagnetic valve is in an automatic closing state under the condition of power failure, and the situation that the valve cannot be closed due to the failure of the power failure combustible gas alarm is avoided, so that the fuel gas is leaked for a long time.
