Abstract
The invention discloses an indoor gas safety anti-theft system, which comprises a gas pipeline and a gas meter, and is characterized in that an electromagnetic valve is connected in series to the gas pipeline at the inlet end of the gas meter; a gas meter monitoring circuit is arranged in the gas meter; and the input end and the output end of the gas meter monitoring circuit are connected with the electric pulse signal end of the gas meter and the control end of the electromagnetic valve respectively. The indoor gas safety anti-theft system has the advantages that the gas meter, an anti-detaching meter joint, the electromagnetic valve, a gas alarm or an exhaust fan are integrated, so that safe use of gas is ensured; once someone tries to stop counting of the gas meter for embezzling gas, the electromagnetic valve can be closed for cutting off a gas circuit, so that the gas embezzling idea of a lawbreaker is avoided technologically and psychologically; and if a user forgets to close the valve after use of gas, the electromagnetic valve is closed automatically through a monitoring circuit of the system, gas is prevented from leaking, the production cost is lowered, a battery is not required to be replaced, inspection is not required, and safety, theft prevention, energy saving and environmental friendliness are realized.
Description
Technical field
The present invention relates to a kind of indoor gas safety, burglary protection system, be used for the 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.No matter be that safety or antitheft all can't guarantee in use, malignant events such as combustion gas leakage, blast take place in succession.The lawless person utilizes the defective on the mounting technique to steal combustion gas repeatedly, the generation of the theft phenomenon of having no idea fundamentally to prevent.The theft combustion gas is the arch-criminal that combustion gas is revealed, and 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 pollutes to environment, and administration expenses, Master Cost and manpower expense increase.
Summary of the invention
The present invention aims to provide the gas meter system of cover safety and antitheft, to solve existing technology because the problem that exists defective mounting to cause safety and anti-theft gaseous in the combustion gas use all can't guarantee.
Technological scheme of the present invention is: a kind of indoor gas safety, burglary protection system, comprise gas pipeline and gas meter, and it is characterized in that, on the gas pipeline of gas meter entry end, be in series with solenoid valve; The gas meter supervisory circuit is housed in gas meter, and the input end of this gas meter supervisory circuit is connected with the electrical pulsing signal end of gas meter and the control end of solenoid valve respectively with output terminal.
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 connects solenoid valve or/and ventilating fan, in case there is combustion gas to reveal, fuel gas alarm is closed solenoid valves or started ventilating fan when sending alarm signal.
Described gas meter supervisory circuit adopts microprocessor, has or not electrical pulsing signal output to convert corresponding high and low level into gas meter, is used for closing of control electromagnetic valve.
Adopt joint to be connected between the entry end of described gas meter and the gas pipeline with tamper function.
Advantage of the present invention is: through 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 have the people to attempt to usurp combustion gas through stopping the gas meter counting, the present invention can close the solenoid valve shuts gas circuit, has stopped the lawless person technically and psychologically and has stolen the thought of combustion gas; Cost of production reduces, and need not change battery, need not inspection, has accomplished safety, antitheft, energy-saving and environmental protection.
Description of drawings
Fig. 1 is an overall formation schematic representation of the present invention;
Fig. 2 is a gas meter supervisory circuit block diagram of the present invention.
Embodiment
Referring to Fig. 1 and Fig. 2, a kind of indoor gas safety of the present invention, burglary protection system comprise gas pipeline 4 and gas meter 9, on the gas pipeline 4 of gas meter 9 entry ends, are in series with solenoid valve 5.Gas meter supervisory circuit 8 is housed in gas meter 9; The input end of this gas meter supervisory circuit 8 respectively with the electrical pulsing signal end A (being the output terminal of photoelectric receiving tube 91 among Fig. 2) of gas meter 9, 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 there is combustion gas to reveal, fuel gas alarm 2 is closed solenoid valve 5 or/and start ventilating fan 3 when sending alarm signal, cut off fuel gas source; Discharge the combustion gas of revealing, guaranteed the Security that combustion gas is used.
Adopt existing various joints 7 to be connected between the entry end of described gas meter 9 and the gas pipeline 4 with tamper function.
Referring to Fig. 2, described gas meter supervisory circuit 8 adopts microprocessor (or PLC), has or not electrical pulsing signal output to convert corresponding high and low level into gas meter 9, is used for closing of control electromagnetic valve 5.
Whether the flow rotating disk that gas meter supervisory circuit 8 is used to monitor gas meter 9 is in running; The combustion gas user is when using combustion gas; The flow rotating disk should turn round, and light-emitting tube is transmitted into photoelectric receiving tube 91 through the aperture of flow rotating disk, and 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 electromagnetic valve 5 is closed the cut-out combustion gas, reaches the purpose of stealing combustion gas with regard to effectively having prevented through stopping the gas meter running like this.After the user uses combustion gas, to forget and close gas valve, the counter of gas meter shuts down, monitoring circuit 8 output high level, control electromagnetic valve 5 is closed and is cut 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 equally applicable to the present invention by being located at magnet on the flow rotating disk to the induction of dry reed-pipe and obtain (existing technology).Monitoring circuit 8 of the present invention 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 handle, and belongs to the technological scheme of the present invention's protection equally.
