Abstract
A kind of fuel gas alarm, comprises gas monitoring probe, control circuit, four Sparkles relays, loudspeaker, reset switch, conventional lamp switch.Detection signal is passed to control circuit by gas monitoring probe, provides electronic signal that loudspeaker is given the alarm after control circuit process, controls four Sparkles relays simultaneously and closes to start the equipment be connected with Sparkles relay; Its advantage is: gas monitoring probe can be separated with body, can be contained in the optional position wanting to monitor; Alarm is equipped with conventional lamp switch, and during generation gas leakage, automatically starting lamp lighting, improves security performance; Can not electric spark be produced during this alarm work, eliminate the risk that electric spark ignites combustion gas; The relay that alarm controls is in parallel with electric switch, does not affect the normal use of electrical equipment.
Description
Technical field
The utility model relates to a kind of safety interaction fuel gas alarm.
Background technology
Along with widely using of rock gas and liquefied gas, safe gas problem is more and more outstanding.And traditional fuel gas alarm can only reach certain value in indoor fuel gas concentration and gives the alarm, source of the gas can not be cut off, reduce indoor fuel gas concentration.When there is gas leakage, the electric spark produced during device for switching just likely ignites combustion gas, frees blast.Therefore the security incident occurred because of gas leakage still happens occasionally.
Summary of the invention
The technical problems to be solved in the utility model is to overcome the defect that conventional gas is reported to the police, and provides a kind of novel gas alarm, when gas leakage occurs and alarm, can not only can also start lighting device by automatic safe.Additionally provide several extra interface can to link other safety installations such as vent fan and solenoid valve simultaneously.
The technical scheme that the utility model adopts is: a kind of fuel gas alarm, comprises gas monitoring probe, control circuit, four Sparkles relays, loudspeaker, reset switch, conventional lamp switch.It is characterized in that: gas monitoring probe can be separated with body, the optional position wanting to monitor can be contained in; Detection signal is passed to control circuit by gas monitoring probe, provides electronic signal that loudspeaker is given the alarm after control circuit process, controls four Sparkles relays simultaneously and closes to start the equipment be connected with Sparkles relay; Commonly use switch in parallel with lighting, connect with light fixture for one in four Sparkles relays, its excess-three is individual can arbitrarily and vent fan, electromagnetic shut-off valve and other devices in series; Switch in parallel commonly used by Sparkles relay and electrical equipment, do not affect electrical equipment and normally uses.After danger is removed, by reset switch, alarm is removed and report to the police and get back to original state.
The utility model has the advantages that:
1, gas monitoring probe can be separated with body, can be contained in the optional position wanting to monitor;
2, alarm and lighting link, and during generation gas leakage, automatically starting lamp lighting, improves security performance;
3, alarm is equipped with conventional lamp switch, does not need additional configuration lamp switch;
4, the relay adopted is Sparkles relay, can not produce electric spark and ignite combustion gas;
5, the relay that controls of alarm is in parallel with electric switch, does not affect the normal use of electrical equipment.
Accompanying drawing explanation
Fig. 1 is the structure that relates to of the utility model and circuit connection diagram.
In figure, A-gas monitoring probe, B-reset switch, C-loudspeaker, D-vent fan, E-electromagnetic shut-off valve, other equipment of F-, G-lighting, K1-Sparkles relay, K2-commonly use lamp switch.
Specific embodiments
As shown in drawings 1, the present invention includes gas monitoring probe, control circuit, four Sparkles relays, loudspeaker, reset switch, conventional lamp switch.Detection signal is delivered to control circuit by gas monitoring probe, by control circuit, the signal received is processed, outwards sending electronic signal makes loudspeaker give the alarm, and controls four Sparkles relays and close to start the equipment be connected with Sparkles relay.
The principle of the present embodiment is as follows: resident living power utility powers to whole circuit.When combustion gas is not revealed, gas monitoring probe can't detect signal, and four Sparkles relays all do not work.The electrical equipment be connected with Sparkles relay, by conventional switch control rule, can normally work.After gas monitoring probe detects combustion gas, signal to control circuit immediately, control circuit then sends electronic signal makes loudspeaker give the alarm, and controls that four Sparkles relays are closed starts lighting, vent fan, electromagnetic shut-off valve by force, can source of the gas be cut off, reduce indoor fuel gas concentration.Adopt Sparkles relay simultaneously, whole circuit disconnect and closed time all can not produce electric spark, ensure further to use gas safety.
