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-resisting system, for safe handling and the anti-theft gaseous of indoor gas measurement instrument.
Background technology
The mounting means of existing gas meter, flow meter all adopts independent mounting means, and gas meter, flow meter, solenoid valve, antitheft, safety, exhaust system are provided by different producers, all independent installation.Be no matter in use safe or antitheftly all cannot guarantee, the malignant events such as gas leakage, blast occur in succession.Lawless person utilizes the defect in field engineering to steal repeatedly combustion gas, the generation of the theft phenomenon of having no idea fundamentally to prevent.Theft combustion gas is the arch-criminal of gas leakage, to the country and people, has caused great loss.
For all there is the behavior that hits out against theft of inspection team the gas company that avoids theft, adopt IC-card gas meter, flow meter and use battery-operatedly, all to change lithium battery every year, refuse battery is to environment, and managerial cost, Master Cost and manpower expense increase.
Summary of the invention
The present invention aims to provide a set of safety and antitheft gas meter, flow meter system, to solve prior art due to the problem that exists defective mounting to cause the safety of combustion gas in using and anti-theft gaseous all cannot guarantee.
Technical scheme of the present invention is: a kind of indoor gas safety, burglary-resisting system, comprise gas pipeline and gas meter, flow meter, and it is characterized in that, on the gas pipeline of gas meter, flow meter inlet end, be in series with solenoid valve; Gas meter, flow meter supervisory circuit is housed in gas meter, flow meter, and the input end of this gas meter, flow meter supervisory circuit is connected with the electric impulse signal end of gas meter, flow meter and the control end of solenoid valve respectively with output terminal.
Described gas meter, flow meter, solenoid valve and gas meter, flow meter supervisory circuit are by low-tension supply supply power.
Also be provided with fuel gas alarm, its control output end connected electromagnetic valve is or/and exhaust fan, once have gas leakage, fuel gas alarm shut electromagnetic valves or start exhaust fan when sending alerting signal.
Described gas meter, flow meter supervisory circuit adopts microprocessor, has or not electric impulse signal output to be converted to corresponding high and low level gas meter, flow meter, for controlling closing of solenoid valve.
Between the inlet end of described gas meter, flow meter and gas pipeline, adopt the joint with tamper function to be connected.
Advantage of the present invention is: by gas meter, flow meter, meter connector, solenoid valve, fuel gas alarm or exhaust fan being fused into an integral body, guaranteed the safe handling of combustion gas; Once there be people to attempt to usurp combustion gas by stopping gas meter counting, the present invention can cut off gas circuit by shut electromagnetic valve, has stopped technically and psychologically lawless person and has stolen the thought of combustion gas; Production cost reduces, and need not change battery, without inspection, has accomplished safe, antitheft, energy-saving and environmental protection.
Accompanying drawing explanation
Fig. 1 is overall formation schematic diagram of the present invention;
Fig. 2 is gas meter, flow 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-resisting system, comprise gas pipeline 4 and gas meter, flow meter 9, on the gas pipeline 4 of gas meter, flow meter 9 inlet ends, is in series with solenoid valve 5.Gas meter, flow meter supervisory circuit 8 is housed in gas meter, flow meter 9, the input end of this gas meter, flow meter supervisory circuit 8 is the output terminal of photoelectric receiving tube 91 in Fig. 2 with the electric impulse signal end A(of gas meter, flow meter 9 respectively), the output terminal of gas meter, flow meter supervisory circuit 8 is connected with the control end of solenoid valve 5.Described gas meter, flow meter 9, solenoid valve 5 and gas meter, flow meter supervisory circuit 8 are by low-tension supply 10 supply powers.
Also can be provided with fuel gas alarm 2, can in the control output end of described fuel gas alarm 2, be connected with solenoid valve or/and exhaust fan 3, once there be gas leakage, fuel gas alarm 2 when sending alerting signal shut electromagnetic valve 5 or/and start exhaust fan 3, cut off fuel gas source, discharge the combustion gas of revealing, guaranteed the security that combustion gas is used.
Between the inlet end of described gas meter, flow meter 9 and gas pipeline 4, adopt the existing various joint 7 with tamper function to be connected.
Referring to Fig. 2, described gas meter, flow meter supervisory circuit 8 adopts microprocessor (or PLC), has or not electric impulse signal output to be converted to corresponding high and low level gas meter, flow meter 9, for controlling closing of solenoid valve 5.
Whether gas meter, flow meter supervisory circuit 8 is turning round for monitoring the flow rotating disk of gas meter, flow meter 9, gas user is when being used combustion gas, 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 electric impulse signal, the quantity that records electric pulse by counter 92 below reaches the object of metering, and the stoichiometric number of combustion gas is shown by display 93.If someone wants to steal combustion gas, must in the situation that crossing, gas-flow make flow rotating disk stop operating.Once rotating disk stops operating, gas meter, flow meter supervisory circuit 8 output high level, control solenoid valve 5 and close cut-out combustion gas, reach the object of stealing combustion gas like this with regard to effectively having prevented by stopping gas meter, flow meter running.When user uses after combustion gas, forget closing gas valve door, the counter of gas meter, flow meter shuts down, monitoring 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, flow meter 9 also can obtain (prior art) to the induction of tongue tube by the magnet being located on flow rotating disk, is equally applicable to the present invention.Monitoring circuit 8 of the present invention also can adopt the acquisition count pulse that interacts of magnet and tongue tube, adopts the circuit pulse signals of microprocessor or other identical functions to process, and belongs to equally the technical scheme of the present invention's protection.
