Normally-closed intelligent management device for domestic gas system

Abstract

The invention provides a normally-closed intelligent management device for a domestic gas system. The normally-closed intelligent management device comprises a gas flow meter (1), a microelectronic processor (2), a wireless signal receiver (3), a built-in electric valve (4), a gas appliance (5), electronic switch annunciators (6) and a gas pipeline (7). The normally-closed intelligent management device is characterized in that an integrated circuit board is integrated through the wireless signal receiver (3) and the microelectronic processor (2), the integrated circuit board is arranged in thegas flow meter (1), the built-in electric valve (4) is arranged in the gas flow meter (1) and is in a closed state, one end of the built-in electric valve is externally connected with a municipal gaspipe, and the other end of the built-in electric valve is connected with the gas pipeline (7) and the gas appliance (5); the electronic switch annunciators (6) are connected with a burner switching valve and an ignition switching valve which are driven by a thermocouple in a flame-out protection device of the gas appliance (5) in parallel; and the gas appliance (5) comprises a gas cooker (51) anda gas water heater (52), and the electronic switch annunciators (6) comprise a gas cooker electronic switch annunciator (61) and a gas water heater electronic switch annunciator (62).

Description

technical field [0001] The invention relates to an intelligent management device, in particular to an intelligent management device for a normally closed household gas system. Background technique [0002] With the promotion and use of piped gas, the issue of safe use of gas has received more widespread attention. At present, household gas safety devices mainly include: gas leakage alarms, flameout protection devices that come with gas appliances (including gas stoves, gas water heaters, etc.). Among them, the former uses the working principle of semiconductors to detect the gas with sufficient concentration leaked from the pipeline system in the detectable effective area, so as to issue a gas leakage alarm in the form of sound and light alarm; the latter only uses the principle of heat conduction , to provide safety self-locking protection to cut off the gas supply for gas appliances that are not in use. This type of single safety device has a single safety measure, is not...
