Description
Technical field
The detection of this utility model inflammable gas and blocking vessel, belong to environmental monitoring technology field。
Background technology
Gas-fired equipment is requisite the articles for daily use in family life, including gas range, natural gas range and gas heater etc., but the problems such as leakage in use can be there is in these equipment, mainly include the toxic gas such as methane and carbon monoxide due to combustion gas, and these gases are all colorless and odorless, be difficult to be found by user after gas leakage, thus human body is caused significant impact, when indoor fuel gas reaches certain density, the accident such as can set off an explosion occurs, and causes great social danger。
In prior art, there are some gas alarm equipment, but these equipment can only play alarm function, it is impossible to automatically block combustion gas, therefore when indoor do not have personnel, or when indoor occupant is sleeping, all cannot stop the leakage of combustion gas。
Additionally, the a lot of gas-cookers used in prior art are both provided with leaking automatic blocking system, namely, when gas-cooker leaks gas, automatically block combustion gas, but this system can only block the leakage of gas-cooker itself, when there is leakage in pipeline between source of the gas and gas-cooker, this system does not just have any effect, and present stage, the pipeline adopted between source of the gas and gas-cooker is plastic flexible pipe, life-time service will necessarily be aging, thus producing leakage hidden danger；Further, blocking system needs battery to control electromagnetic valve automatically, owing to electromagnetic valve is constantly in duty, therefore battery power consumption is very big, it is necessary to often change, and when dead battery, gas-cooker also cannot employ, and affects the use of user。
Utility model content
This utility model overcomes the deficiency that prior art exists, provide a kind of inflammable gas detection and blocking vessel, gas solenoid valve is arranged at source outlet place, and adopts flammable gas detector to control the folding of gas solenoid valve, fundamentally control the leakage of combustion gas。
In order to solve above-mentioned technical problem, the technical solution adopted in the utility model is: inflammable gas detection and blocking vessel, including source of the gas and flammable gas detector, the gas outlet of described source of the gas is connected with gas-fired equipment, air delivering pipeline between described source of the gas and gas-fired equipment is provided with gas solenoid valve, described gas solenoid valve is provided with electromagnetic valve and controls switch, described electromagnetic valve controls the signal input part of switch and is connected with the signal output part of flammable gas detector, described flammable gas detector controls electromagnetic valve and controls to switch on-off electricity, described flammable gas detector controls switch with electromagnetic valve and is all connected with power supply。
Described flammable gas detector is also associated with controlling electromagnetic valve and controls the chronotron of switch。
The outfan of described flammable gas detector is also associated with the buzzer for reporting to the police。
Described power supply and flammable gas detector and electromagnetic valve control to be provided for electric switch between switch。
This utility model compared with prior art has the advantages that
1, gas solenoid valve is arranged at the exit of source of the gas, when leaking air, between block the supply of source of the gas, no matter be gas-fired equipment gas leakage or the pipeline gas leakage connecting between gas-fired equipment and source of the gas, can effectively be blocked。
2, flammable gas detector controls the folding of gas solenoid valve, and the shut-in time of gas solenoid valve is controlled by chronotron, when flammable gas detector sends gas leakage signal, buzzer first carries out alarm, if user of service controls leakage within a certain period of time in time, then gas solenoid valve will not power-off, thus do not affect user use combustion gas。
Accompanying drawing explanation
Below in conjunction with accompanying drawing, this utility model is described further。
Fig. 1 is structural representation of the present utility model。
In figure 1 be power supply, 2 for power switch, 3 for flammable gas detector, 4 for buzzer, 5 for electromagnetic valve control switch, 6 for gas solenoid valve, 7 for source of the gas, 8 be gas-fired equipment。
Detailed description of the invention
As shown in Figure 1, the detection of this utility model inflammable gas and blocking vessel, including source of the gas 7 and flammable gas detector 3, the gas outlet of described source of the gas 7 is connected with gas-fired equipment 8, air delivering pipeline between described source of the gas 7 and gas-fired equipment 8 is provided with gas solenoid valve 6, described gas solenoid valve 6 is provided with electromagnetic valve and controls switch 5, described electromagnetic valve controls the signal input part of switch 5 and is connected with the signal output part of flammable gas detector 3, described flammable gas detector 3 controls electromagnetic valve and controls the power on/off of switch 5, described flammable gas detector 3 controls switch 5 with electromagnetic valve and is all connected with power supply。
Described flammable gas detector 3 is also associated with controlling electromagnetic valve and controls the chronotron of switch。
The outfan of described flammable gas detector 3 is also associated with the buzzer 4 for reporting to the police。
Described power supply 1 and flammable gas detector 3 and electromagnetic valve control to be provided for electric switch 2 between switch 5。
Specific works process:
By this system energization, connect power switch 2, now flammable gas detector 3 and electromagnetic valve control switch 5 obtain electric, and indoor combustion gas is detected by flammable gas detector 3, and electromagnetic valve controls to switch the unlatching of 5 control gas solenoid valves 6, once inflammable gas concentration over-standard, the circuit of flammable gas detector 3 internal control buzzer 4 is powered to buzzer 4 so that buzzer 4 is reported to the police, while warning, chronotron is started working, and now electromagnetic valve control switch 5 remains powered on state。
After the chronotron time; if concentration continues to increase; flammable gas detector 3 controls switch 5 offer power-off signal to electromagnetic valve; electromagnetic valve controls the control electric current of switch 5 and is disconnected; make electromagnetic valve control to switch 5 and close gas solenoid valve 6 because of dead electricity; thus gas circuit is cut off, play safeguard protection effect。
If, in the chronotron time period, gas concentration decreases, then flammable gas detector 3 will not control switch 5 offer power-off signal to electromagnetic valve, from without gas solenoid valve 6 is closed, thus preventing flammable gas detector 3 from occurring when test errors or user block leakage in time, gas solenoid valve 6 is controlled switch 5 closedown by electromagnetic valve。
Above in conjunction with accompanying drawing, embodiment of the present utility model is explained in detail, but this utility model is not limited to above-described embodiment, in the ken that those of ordinary skill in the art possess, it is also possible to make various change under the premise without departing from this utility model objective。
