Description
Technical field
This utility model relates to fuel gas alarm technical field, especially relates to a kind of time-controlled type flammable gas alarm.
Background technology
Resident's gas safe is always the emphasis of governments at all levels, enterprise security manager, is also a difficult point, although do simultaneously
Substantial amounts of precaution by persons, equipment and techniques work, but the accidents such as the leakage poisoning caused during natural gas motorcar, blast
Emerge in an endless stream.At present resident family is generally mounted with flammable gas alarm, prevents the generation of gas accidents.This report
Alert device is made up of combustible gas detection device and the electromagnetic valve being arranged on gas pipeline mostly, when detection device detects can
When the concentration of combustion gas body reaches alarming value, produce a signal to electromagnetic valve by valve closing, play blocking-up natural gas leaking
Effect.Existing alarm is in use primarily present the problem of four aspects, and one is to detect plant failure rate relatively
Height, wrong report, the not phenomenon such as report are frequent, cause electromagnetic valve to be closed the most without reason or inoperative during concentration over-standard；Two is to visit
Survey device sometimes because installation site or other problem cause the natural gas to revealing insensitive, automatic interlock disabler
Cause the generation of some accidents；Three is solenoid valve failure, and when having alarm signal, electromagnetic valve does not cuts out；Four is in not close chamber
Interior main valve occurs to leak and in the case of alarm fault without effective control device.For this, our utility model is a kind of new
Time-controlled type flammable gas alarm, solves above technical problem.
Utility model content
The purpose of this utility model is to provide a kind of increase time control on the basis of existing alarm electromagnetic valve automatic interlock is protected
The time-controlled type flammable gas alarm of automatic interlock function.
The purpose of this utility model can be achieved by the following technical measures: time-controlled type flammable gas alarm, this time-controlled type
Flammable gas alarm include combustable gas concentration probe, central processing unit, time switch, gas leakage control circuit and
Electromagnetic valve, this combustable gas concentration probe is connected to this central processing unit, the concentration of detection combustion gas, and surpasses in gas concentration
Timestamp, the signal that will exceed standard is transferred to this central processing unit, and this central processing unit sends alarm signal after receiving the signal that exceeds standard
Number giving this gas leakage control circuit, this gas leakage control circuit is connected to this central processing unit and this electromagnetic valve, and
Shutoff signal being transferred to after receiving alarm signal this electromagnetic valve cut off by this electromagnetic valve, this time switch is connected to this electricity
Magnet valve and this central processing unit, and in the given time this electromagnetic valve is cut off under the control of this central processing unit.
The purpose of this utility model realizes also by following technical measures:
This time-controlled type flammable gas alarm also includes LCDs, and this LCDs is connected to this central processing unit,
This central processing unit sends alarm signal to this LCDs when gas concentration exceeds standard, and makes this LCDs display report
Alarming information.
This time-controlled type flammable gas alarm also includes audible-visual annunciator, and this audible-visual annunciator is connected to this central processing unit,
This central processing unit sends alarm signal to this audible-visual annunciator when gas concentration exceeds standard, and makes this audible-visual annunciator carry out sound
Light is reported to the police.
Time-controlled type flammable gas alarm in this utility model, mainly by detection alarm device, electromagnetic valve two large divisions's group
Become.Wherein detection alarm part is mainly made up of timed unit, gas concentration probe, electromagnetic valve control part, plays master
The time control wanted, leakage alarm automatic interlock function；Electromagnetic valve is arranged in fuel gas pipeline, receives the closedown of detection device
During signal, electromagnetic valve is automatically switched off.Just commonly using gas time generation leakage preferential execution leakage alarm automatic interlock defencive function.
Time-controlled type flammable gas alarm in this utility model increases time control automatic interlock merit on the basis of former detectors
Can, user can arbitrarily set closedown and the opening time of plurality of electromagnetic valve.Time control automatic interlock function can allow resident arrange early,
In, evening use the gas time, other times are automatically switched off, and reduce the time of natural gas leaking to greatest extent；When just commonly using gas
Between occur that leakage is preferential performs leakage alarm automatic interlock defencive function.When combustible gas probe is detected with gas leakage
Time, alarm sends sound and light alarm, and electromagnetic valve is automatically switched off.The very convenient resident of integrated setting uses, particularly convenient
Busy young and old people, directly reduces the security risk forgetting to close the band of gas.
Accompanying drawing explanation
Fig. 1 is the structure chart of a specific embodiment of time-controlled type flammable gas alarm of the present utility model.
Detailed description of the invention
For making above and other objects, features and advantages of the present utility model to become apparent, cited below particularly go out preferable reality
Execute example, and coordinate shown in accompanying drawing, be described in detail below.
As it is shown in figure 1, the structure chart that Fig. 1 is time-controlled type flammable gas alarm of the present utility model.This time-controlled type combustible gas
Body alarm by combustable gas concentration probe 2, central processing unit 3, LCDs 4, audible-visual annunciator 5, time switch 6,
Gas leakage control circuit 7 and electromagnetic valve 8 form.
Combustable gas concentration probe 2 is connected to central processing unit 3, detects the concentration of combustion gas 1, and when gas concentration exceeds standard,
The signal that will exceed standard is transferred to central processing unit 3, and central processing unit 3 is connected to LCDs 4, receive exceed standard signal time
