The bottom end of a gas inlet pipe of the traditional gas meter is provided with a through hole valve seat; a pressure sensor is arranged above the valve seat; the valve seat is internally provided with an electric control valve; the inner side of a panel in front of a meter body is provided with a control circuit board, a liquid crystal instrument and an IC card circuit; the control circuit board is connected with the liquid crystal instrument, the IC card circuit and the electric control valve respectively by circuits; and the circuit board consists of a CPU, a valve circuit, a display circuit, the IC card circuit and signal acquisition. The intelligent IC card gas meter eliminates much inconvenience caused by manual meter reading. A user can buy gas by an IC card, the bought gas quantity can be input into the gas meter through an IC card seat, and the control valve is automatically opened, so that the gas meter can work normally. Simultaneously, the user can inquire by keys, and the bought gas quantity and the rest gas quantity can be displayed by a liquid crystal display screen, so that the intelligent gas meter brings greater convenience to the user.
Description
Technical field
The utility model belongs to measurement of gas flow technology, specifically, is a kind of intelligent gas meter that electronics demonstration and code-disc Presentation Function are arranged.
Background technology
The gas meter, flow meter that tradition is used mainly is made up of draft tube, escape pipe, air bag, table body, tolerance counter, code-disc.When gas from the draft tube air bag of flowing through, when being flowed out by the gas outlet then, the tolerance counter carries out flow metering, the user can recognize gas consumption by code-disc, but the user can't learn the tolerance of buying and the residue tolerance, there is defective like this in traditional gas meter, flow meter, and is unsatisfactory.
The utility model content
The purpose of this utility model is, a kind of simple in structure, practical, gas meter, flow meter easily is provided, the user in the process of using gas meter, flow meter, the institute's tolerance of buying of plug-in card inquiry at any time and remain tolerance.
The utility model has been achieved in that draft tube, escape pipe, air bag, table body, tolerance counter, code-disc, in the bottom of the draft tube 1 of gas meter, flow meter the port valve seat is installed, and is provided with motor-operated control valve 12 in the valve seat; In the panel of table body 9 front portions, control circuit board 11, LCDs 4, IC-card seat 14 are installed, this control circuit board 11 is connected with LCDs 4, IC-card seat 14, motor-operated control valve 12 respectively.Said control circuit board 11, mainly be made up of CPU, valve circuit, display circuit, IC-card circuit, signal acquisition circuit, the valve circuit that is connected with motor-operated control valve 12, the display circuit that is connected with LCDs 4, the IC-card circuit that is connected with IC-card seat 14, the signal acquisition circuit that is connected with tolerance counter 3, the warning circuit that is connected with alarm socket 6 are connected with cpu circuit respectively.
The IC-card intelligent gas meter of the utility model has been removed the inconvenience that manual metering brings from.The gas quantity that the tolerance counter is gathered is handled through CPU, is shown by the liquid crystal instrument.The user buys combustion gas by IC-card, and will buy in the tolerance input table by the IC-card seat, and operation valve is just opened automatically, and gas meter, flow meter just can normally use.Simultaneously, the user can inquire about by button, LCDs also can show the tolerance of buying and the residue tolerance.Tolerance is used up in table, and LCDs shows that purchase volume is 0, send instructions to valve circuit under the CPU, and the closed control valve valve, LCDs prompting user in time purchases gas.The user is bought tolerance and residue tolerance by inquiry, only needs plug-in card in the IC-card circuit, just can obtain the electronics demonstration of two apparent intelligent display-----liquid crystal and the machinery of code-disc and show, greatly facilitates the user.
