Abstract
The utility model relates to a gas leakage alarm and closing device. The device is provided with two mechanisms which are a gas detection alarm mechanism and a gas valve automatic closing mechanism. The main points of the utility model lie in that a gas valve automatically closes a signal line which is connected via a solenoid valve, the solenoid valve is closed and gas is cut off when the solenoid valve receives an induction signal about that gas leakage detected by a connected gas detection sensor happens to a gas pipeline, and about that concentration reaches an alarm value. Moreover, the solenoid valve cannot restore to start automatically. After a leakage fault of the pipeline is removed, the solenoid valve can be started manually to make the gas run. The gas leakage alarm and closing device effectively solves the technical problem that a gas leakage alarm gives out sound-light alarm and a problem of automatic closing of a valve, and is suitable for structural improvement of the same kind of products.
Description
Technical field
The utility model relates to a kind of detection alarm device, is a kind of gas leakage alarm and stopping device.
Background technology
The gas leakage detecting alarm of selling in the market, only have the detection alarm function, and when gas pipeline or fuel gas bottle had gas leakage, alarm can send sound and light alarm, and this need to notify the user to turn off valve by gas leakage supervision department.If the user does not exist, along with increasing of inflammable gas, the security incident such as likely blast at any time.
Summary of the invention
The utility model, in order to adapt to user's demand, is intended to provide to this area a kind of gas leakage alarm and stopping device, to solve Fuel Gas Leak Alarm, sends the technical matters of sound and light alarm and automatic-closing valve.The utility model is achieved through the following technical solutions.
A kind of gas leakage alarm and stopping device, described device is provided with two mechanisms, the one, combustion gas detection alarm mechanism, the 2nd, the burnt gas valve automatic-closing mechanism, combustion gas detection alarm mechanism comprises face-piece, drain pan, described face-piece, alarm assemblies is set between drain pan, described alarm assemblies is by alarming horn, the combustion gas acquisition sensor, signal wire, the power supply buck rectifier forms, and drawn by power lead, its main points are that burnt gas valve is closed automatically by solenoid valve and connect signal wire, described solenoid valve is received the combustion gas acquisition sensor connected and is recorded gas pipeline gas leakage is arranged, after concentration reaches the induced signal of alarming value, shut electromagnetic valve immediately, automatically cut off combustion gas.And solenoid valve is can automatically not recover to open, after pipeline is revealed the fault eliminating, manually opened enforcement ventilation.
The utility model structure is comparatively simple, and operation more for convenience, solves the technical matters that Fuel Gas Leak Alarm is sent sound and light alarm and automatic-closing valve effectively, and the scope of application is wider, also is applicable to the architecture advances of like product.
The accompanying drawing explanation
Fig. 1 is the utility model inner structure decomposing schematic representation.
Fig. 2 is the utility model embodiment schematic diagram.
Embodiment
Now by reference to the accompanying drawings the utility model is further described.As shown in Figure 1, 2, in figure, the name of sequence number is called: face-piece 1, power lights 101, button 102, trouble light 103, alarm lamp 104, drain pan 2, alarm assemblies 3, alarming horn 301, combustion gas acquisition sensor 302, signal wire 303, power supply buck rectifier 304, supply socket 4, solenoid valve 5, gas pipeline 6.
This device is provided with two mechanisms, and the one, combustion gas detection alarm mechanism, the 2nd, the burnt gas valve automatic-closing mechanism is relevance, combustion gas detection alarm mechanism comprises face-piece 1, drain pan 2, and alarm assemblies 3 is set between described face-piece, drain pan.Described alarm assemblies consists of alarming horn 301, combustion gas acquisition sensor 302, signal wire 303, power supply buck rectifier 304, and is drawn by power lead 401.Power supply buck rectifier 304 also comprises printed-wiring board (PWB), oversize because of this part name, is omitted the several words of printed-wiring board (PWB), now is illustrated.
Shown in Figure 1, face-piece 1 with drain pan 2 by self-tapping screw by both combinations.
Shown in Figure 2, detecting alarm is mounted on wall, and power supply is powered to it by the power supply buck rectifier by civil power.Solenoid valve 5 is connected on gas pipeline 6.By signal wire 303, be connected with detecting alarm.
Described alarm assemblies 3 one endpiece connecting power lines 401, another endpiece connects signal wire 303, signal wire connected electromagnetic valve 6, described solenoid valve is connected with gas pipeline 7.When detecting alarm detects gas pipeline 6, gas leakage is arranged, when concentration reaches alarming value, will send chimes of doom, the alarm lamp flicker.Synchronous signal will input to solenoid valve 5 by signal wire, and solenoid valve 5 stops fuel gas supply by shut electromagnetic valve after receiving signal.And the solenoid valve of having cut out can not recover to open automatically, after pipeline is revealed fault and is got rid of, artificial manually opened enforcement ventilation, that is to say these two mechanisms in conjunction with the complete design purpose.
