Detailed Description
Detailed description of the preferred embodiment 1
The utility model discloses a device is applicable to the community of living in the present era, and under the old trend of keeping good at home, it is high-rise house mostly, and it is fairly intensive to live in, and fire control safety pressure is fairly serious, in order to improve current house life's safety demand, is necessary to warn the daily use of domestic gas management and remind the self-closing management under the unexpected condition. The device monitors the use of the household gas facility from two levels of daily users and a network monitoring center (which needs external hardware support), improves the safety of the whole community building, and reduces the fire-fighting hidden danger of a high-rise building.
As shown in figures 1-2, the household gas safe use reminding and emergency self-closing device comprises a household alternating current 220v power supply conversion device, a reminding emergency device and an intrinsically safe power-off self-closing electromagnetic valve.
The intrinsically safe power-off self-closing electromagnetic valve is arranged on a gas main pipeline; the household alternating current 220v power supply conversion device is connected with a reminding emergency device, and the reminding emergency device controls the electromagnetic valve to work.
The reminding emergency device comprises an SW 2-reset key, an SW 3-start/stop key, a BZ 1-buzzer and an RL 1-time delay relay, wherein the RL 1-time delay relay controls the working time of the electromagnetic valve and controls the BZ 1-buzzer to work.
The household alternating current 220v power supply conversion device comprises: SW 1-power key, SW 4-optional power key and T1-small transformer 220V/24V, wherein the SW 1-power key and the SW 4-optional power key are connected in parallel and then connected with the T1-small transformer 220V/24V.
The SW 4-optional power key is used for intelligent remote control.
The three keys of the SW 1-power key, the SW 2-reset key and the SW 3-start/stop key are arranged on the small control circuit panel.
When the device is used, a 'power supply' key is firstly pressed down, so that the control circuit is electrified and then is pressed down: when the key starts/stops, the electromagnetic valve in the gas pipeline is powered on, so that the pipeline is switched on, at the moment, a user can normally use various gas equipment at home, meanwhile, the time relay in the control circuit starts timing (the timing time can be manually set on the time relay body, generally 20-30 minutes), when the user uses the gas time to reach a set value, the electromagnetic valve is powered off to cut off a gas pipeline gas source, and meanwhile, the buzzer sounds to give an alarm to remind the user to reset to confirm the alarm. When the user presses the 'reset' key, the buzzer stops and the gas supply resumes. When the user does not use the gas equipment for a short time, the start/stop button can be pressed again to power off the electromagnetic valve and close the gas pipeline, and the function corresponds to that when the gas equipment is frequently used in daytime. If the household gas equipment is not used at night or for a long time, a power key can be pressed to close the control circuit (the function is also suitable for remotely closing the household power supply, so that the control function is connected to a network control center), and finally, the gas main valve is manually closed to ensure safety.
The alarm device also comprises a second-stage delay relay to realize a delay function, and only the buzzer alarms at the moment, but the electromagnetic valve is not closed.
And the gas pipeline electromagnetic valve is closed when the main power supply is powered off. The function is for access when upgrading to the network version for intelligent control in the future.
The utility model discloses only need install an essence safety type solenoid valve (normally closed type) additional in domestic gas pipeline house steward export to through a control circuit, just can realize helping the user to monitor the result of use of gas equipment, avoided losing effective supervision of gas equipment and lead to catching fire the explosion and the gas leakage leads to the vicious circle of indoor personnel poisoning. Through the interlocking relation with the circuit, further intelligent monitoring becomes possible, and the daily operation of a user is facilitated.
