Description
Technical field
This utility model relates to the technical field of gas-fired equipment, is especially a kind of bottle gas security alarm and cuts
Disconnected device.
Background technology
Bottle gas brings conveniently to the life of people due to its portability, has substantial amounts of use at home
Family, and usage amount will not be reduced within considerably long period.But, in recent years, the blast fire of bottle gas
Calamity accident occurs again and again, causes great harm to the security of the lives and property of people.Trace it to its cause the old of mainly rubber tube
Change to cause and rupture, or rubber tube comes off, and cylinder valve or pressure regulator valve leakage etc. cause gas leak to be caused.Therefore,
Prior art occurs in that some leakage warning devices for bottled gas.
As disclosed on State Intellectual Property Office website " a kind of Intelligent gas switch " of Publication No. CN104062936A
Patent, this jet is that collection information is passed to single-chip microcomputer by sensor unit, and single-chip microcomputer is simultaneously connected with alarm, motor；
Single-chip microcomputer judges flame combustion state by the switching-state information collected of sensor unit, gas concentration information, controls
Driven by motor jet is automatically switched off and reports to the police.But, it there is the problem that first, and this device is to open at coal gas
Shutting and be provided with shut-off mechanism, as controlled motor, sensor unit, single-chip microcomputer and intervalometer etc., numerous parts are installed in

The closedown of gas tank valve processed and unlatching.But, it there is the problem that first, and servomotor is the most just arranged on gas tank
Switch on, when servomotor starts, can the switch of moment swivel gas tank, no matter be to rotate forward or reversion, all cannot essence
Really controlling the rotating cycle of gas bottle switch, so, gas bottle switch there will be the phenomenon of excessively rotation, thus causes gas tank
The damage of switch, causes bigger security incident on the contrary；Second, this device monitoring is the gas pressure in gas pipe, and nothing
Method monitors the gas concentration of the leakage accumulated in daily life in using environment, therefore, when in gas pipe, gas pressure does not has
Change and time in surrounding, gas concentration reaches dangerous degree, this device cannot monitor and cannot take to cut off
The action of gas passage.
