Abstract
An indoor gas safety and anti-theft system comprises a gas pipeline and a gas meter and is characterized in that a magnetic valve is in series connection with the gas pipeline at an inlet end of the gas meter. A gas meter monitoring circuit is installed in the gas meter, and an input end and an output end of the gas meter monitoring circuit are respectively connected with an electric pulse signal end of the gas meter and a control end of the magnetic valve. The indoor gas safety and anti-theft system has the advantages that the gas meter, an anti-dismounting meter joint, the magnetic valve, a gas alarming device or a ventilator are integrated, so safe utilization of gas is ensured. The indoor gas safety and anti-theft system turns off the magnetic valve and cuts a gas circuit immediately once a person tries to steal the gas by stopping the counting of the gas meter, so thoughts of a lawless person to steal the gas are eradicated in both the technique aspect and the mentality aspect. When a user turns off the valve in a wrong way after using the gas, the indoor gas safety and anti-theft system can automatically turn off the magnetic valve so as to ensure that the gas cannot leak. The production cost is lowered, a battery does not need to be changed, no monitoring is necessary, and safety, prevention of thievery, energy conservation and environmental protection are achieved.
Description
Technical field
The utility model relates to a kind of indoor gas safety, burglary protection system, is used for safe handling and the anti-theft gaseous of indoor gas measurement instrument.
Background technique
The mounting type of existing gas meter all adopts independent mounting type, and gas meter, solenoid valve, antitheft, safety, exhaust system are provided by different producers, all independent the installation.In use no matter be safe or antitheftly all can't guarantee, the malignant events such as gas leakage, blast occur in succession.The lawless person utilizes the defective on the mounting technique to steal repeatedly combustion gas, the generation of the theft phenomenon of having no idea fundamentally to prevent.The theft combustion gas is the arch-criminal of gas leakage, has caused great loss to the country and people.
For the gas company that avoids theft all has the behavior that hits out against theft of inspection team, to adopt the IC-card gas meter and use battery-operatedly, all will change lithium cell every year, and used battery is to environment, and administration expenses, Master Cost and manpower expense increase.
Summary of the invention
The utility model aims to provide a cover safety and antitheft gas meter system, to solve prior art owing to the problem that exists defective mounting to cause safety in the combustion gas use and anti-theft gaseous all can't guarantee.
The technical solution of the utility model is: a kind of indoor gas safety, burglary protection system, comprise gas pipeline and gas meter, and it is characterized in that, be in series with solenoid valve at the gas pipeline of gas meter entry end; The gas meter supervisory circuit is housed in gas meter, and the input end of this gas meter supervisory circuit is connected with output terminal and is connected control end with solenoid valve with the electrical pulsing signal end of gas meter and is connected.
Described gas meter, solenoid valve and gas meter supervisory circuit are by the low tension power supply supply power.
Also be provided with fuel gas alarm, its control output end connected electromagnetic valve is or/and ventilating fan, in case gas leakage is arranged, fuel gas alarm shut electromagnetic valves or start ventilating fan when sending alarm signal.
Described gas meter supervisory circuit adopts microprocessor, has or not electrical pulsing signal output to be converted to corresponding high and low level gas meter, is used for closing of control solenoid valve.
Adopt the joint with tamper function to be connected between the entry end of described gas meter and the gas pipeline.
The utility model has the advantages that: by gas meter, meter connector, solenoid valve, fuel gas alarm or ventilating fan being fused into an integral body, guaranteed the safe handling of combustion gas; In case there is the people to attempt to usurp combustion gas by stopping gas meter counting, the utility model can cut off gas circuit by shut electromagnetic valve, has stopped technically and psychologically the lawless person and has stolen the thought of combustion gas; Cost of production reduces, and need not change battery, need not inspection, has accomplished safe, antitheft, energy-saving and environmental protection.
Description of drawings
Fig. 1 is overall formation schematic representation of the present utility model;
Fig. 2 is gas meter supervisory circuit block diagram of the present utility model.
Embodiment
Referring to Fig. 1 and Fig. 2, a kind of indoor gas safety of the utility model, burglary protection system comprise gas pipeline 4 and gas meter 9, are in series with solenoid valve 5 at the gas pipeline 4 of gas meter 9 entry ends.Gas meter supervisory circuit 8 is housed in gas meter 9, the input end of this gas meter supervisory circuit 8 is the output terminal of photoelectric receiving tube 91 among Fig. 2 with the electrical pulsing signal end A(of gas meter 9 respectively), the output terminal of gas meter supervisory circuit 8 is connected with the control end of solenoid valve 5.Described gas meter 9, solenoid valve 5 and gas meter supervisory circuit 8 are by low tension power supply 10 supply powers.
Also can be provided with fuel gas alarm 2, can be connected with solenoid valve in the control output end of described fuel gas alarm 2 or/and ventilating fan 3, in case gas leakage is arranged, fuel gas alarm 2 when sending alarm signal shut electromagnetic valve 5 or/and start ventilating fan 3, cut off fuel gas source, discharge the combustion gas of revealing, guaranteed the Security that combustion gas is used.
Adopt existing various joints 7 with tamper function to be connected between the entry end of described gas meter 9 and the gas pipeline 4.
Referring to Fig. 2, described gas meter supervisory circuit 8 adopts microprocessor (or PLC), has or not electrical pulsing signal output to be converted to corresponding high and low level gas meter 9, is used for closing of control solenoid valve 5.
Whether gas meter supervisory circuit 8 is used for the flow rotating disk of monitoring gas meter 9 in running, gas user is when using combustion gas, the flow rotating disk should turn round, light-emitting tube is transmitted into photoelectric receiving tube 91 by the aperture of flow rotating disk, the latter exports continuous electrical pulsing signal, reach the purpose of metering by the quantity of the counter 92 record electrical pulses of back, the stoichiometric number of combustion gas is shown by display device 93.If someone wants to steal combustion gas, must the flow rotating disk be stopped operating.In case rotating disk stops operating, gas meter supervisory circuit 8 output high level, control solenoid valve 5 cuts out the cut-out combustion gas, reaches the purpose of stealing combustion gas with regard to effectively having prevented by stopping the gas meter running like this.After the user uses combustion gas, forget the closing gas valve door, the counter of gas meter shuts down, gas meter supervisory circuit 8 output high level, control solenoid valve 5 cuts out and cuts off the electricity supply, and so just guarantees that combustion gas can not leak from pipeline, guarantees the safe handling of combustion gas.The count pulse of gas meter 9 also can be by being located at magnet on the flow rotating disk to the induction of dry reed-pipe and is obtained (prior art), is equally applicable to the utility model.Gas meter supervisory circuit 8 of the present utility model also can adopt the acquisition count pulse that interacts of magnet and dry reed-pipe, adopts the circuit pulse signals of microprocessor or other identical functions to process, and belongs to equally the technological scheme of the utility model protection.
