Apparatus for alarming and processing gas leakage

Abstract

The invention discloses a gas leakage alarming and processing device. In the device, a gas detection alarm, an electromagnetic valve, an exhaust fan and an automatic telephone dialer are connected onto a controller; a commutating and voltage-stabilizing power, a circuit board and a voltage stabilizing sheet are fixed in the shell of the controller, a switch and an LBD for indication are arranged on the panel of the shell of the controller and a plurality of sockets are also opened on the panel; the exhaust fan is started for forced ventilation to the interior when the gas concentration is higher than an alarm concentration and gas supply is cut off to stop the gas leakage by the controller; if the indoor leaked gas concentration is detected to reach the alarm concentration again after thecut-off of the gas supply, the gas detection alarm sounds again, and the controller starts the exhaust fan again for ventilation and self-locking, meanwhile, the automatic telephone dialer is startedto give the remote alarm to a preset telephone number. The device has simple structure, convenient installation and use, complete function and safety and reliability and can be widely applied to the gas leakage alarm in hotels, restaurants and ordinary households.

Description

technical field [0001] The invention relates to a gas leakage alarm device, which is used for detection and alarm of gas leakage. Background technique [0002] At present, most of the gas leakage alarms sold and used in the market are individuals working independently, with a single alarm function. When an alarm is issued, only a flashing or buzzing warning signal can be issued to remind the user that the indoor gas leakage concentration has exceeded the alarm concentration, but no corresponding measures can be taken to automatically deal with the dangerous situation. However, the actual situation is that when a large amount of leaked gas accumulates indoors, it will cause fire hazards and even be life-threatening. The patent application number is 200310121948.4, and the patent application titled "gas leakage alarm safety control cooker" discloses a new gas leakage alarm device. The gas detection and alarm system is installed in the range hood, and its defect is that it can...

[0002] At present, most of the gas leakage alarms sold and used in the market are individuals working independently, with a single alarm function

When an alarm is issued, only a flashing or buzzing warning signal can be issued to remind the user that the indoor gas leakage concentration has exceeded the alarm concentration, but no corresponding measures can be taken to automatically deal with the dangerous situation

However, the actual situation is that when a large amount of leaked gas accumulates indoors, it will cause fire hazards and even life-threatening

The patent application number is 200310121948.4, and the patent application titled "gas leakage alarm safety control cooker" discloses a new gas leakage alarm device. The gas detection and alarm system is installed in the range hood, and its defect is that it cannot be detected in time. The density is higher than that of air and the liquefied gas is easy to accumulate near the ground after leakage; at the same time, the detection sensitivity and detection life of the detector element will be greatly affected by the long-term exposure to oily smoke environment; the gas shut-off system in the gas stove can only be used for The leakage caused by the accidental extinguishing of the gas stove or the lax closing of the gas stove can prevent the continuous leakage of gas, but the leakage caused by the damage of the gas hose and other non-stove appliances cannot prevent the continuous leakage of gas
