Description
Technical field
The utility model relates to the intelligent gas meter field, relates in particular to a kind of gas meter, flow meter antiwithdrawal device.
Background technology
The means of stealing gas have now got more and more, and its purpose has only one, is exactly the profit for oneself, ignore the interests of infringement gas company.At present, take the needle except adopting magnet absorption gas meter, flow meter, be taking the needle of metering gas static outside, What is more, directly the mode by demolition diaphragm gas meter reaches the purpose of gas steathily.How suppressing the loss that steathily gas behavior brings to gas company is urgent problem.
The utility model content
Embodiment of the present utility model provides a kind of gas meter, flow meter antiwithdrawal device, is used to solve owing to damage the problem that gas meter, flow meter causes combustion gas to be revealed.
For achieving the above object, embodiment of the present utility model adopts following technical scheme:
A kind of gas meter, flow meter antiwithdrawal device, comprise tamper circuit and touch-pressure switch, described tamper circuit comprises control single chip computer, one end of described touch-pressure switch is connected with the table of gas meter, flow meter lid, the other end of described touch-pressure switch is connected with the signal input part of described control single chip computer, and the pass valve signal output terminal of described control single chip computer is connected with the motor that drives air-supplying valve by amplifying circuit.
Further, in order to realize to open once more after the described motor that removes to drive air-supplying valve is with valve closing the valve of air feed, described control single chip computer is provided with the valve opening signal output terminal, and described valve opening signal output terminal is connected with the motor that drives air-supplying valve by described amplifying circuit.
The gas meter, flow meter antiwithdrawal device that the utility model embodiment provides, end at described touch-pressure switch is connected with the table lid of gas meter, flow meter, when the other end of described touch-pressure switch is connected with the signal input part of described control single chip computer, air-supplying valve is in opening, when described gas meter, flow meter is disassembled, one end of described trigger switch and the table of described gas meter, flow meter lid disconnect, make the magnitude of voltage of described trigger switch change, and then changed the signal that trigger switch provides for the signal input part of described control single chip computer and changed, make the pass valve signal output terminal output of control single chip computer close valve signal, close valve signal and amplify the motor of controlling described driving air-supplying valve afterwards by amplifying circuit, make described air-supplying valve close, thereby solved owing to damage the problem that gas meter, flow meter causes combustion gas to be revealed.
Description of drawings
The structural representation of the gas meter, flow meter antiwithdrawal device that Fig. 1 provides for the utility model embodiment;
Fig. 2 is the circuit diagram one of gas meter, flow meter antiwithdrawal device shown in Figure 1;
Fig. 3 is the circuit diagram two of gas meter, flow meter antiwithdrawal device shown in Figure 1.
Embodiment
The utility model embodiment provides a kind of gas meter, flow meter antiwithdrawal device, is used to solve owing to damage the problem that gas meter, flow meter causes combustion gas to be revealed.
Below in conjunction with accompanying drawing the gas meter, flow meter antiwithdrawal device that the utility model embodiment provides is described in detail.
Shown in Fig. 1-2, the gas meter, flow meter antiwithdrawal device that the utility model embodiment provides, comprise tamper circuit 1 and touch-pressure switch 2, described tamper circuit 1 comprises control single chip computer 11, one end of described touch-pressure switch 2 is connected with the table of gas meter, flow meter lid 3, the other end of described touch-pressure switch 2 is connected with the signal input part 111 of described control single chip computer 11, and the pass valve signal output terminal 112 of described control single chip computer 11 is connected with the motor 4 that drives air-supplying valve by amplifying circuit 12.
In the present embodiment, described touch-pressure switch is fixed on the described tamper circuit, described tamper circuit is the form of pcb board, when carrying out gas meter, flow meter dress table, strength by the table lid is pressed touch-pressure switch, make the signal input part that links to each other with described touch-pressure switch place 0, when gas meter, flow meter is destroyed or is dismantled, external force from watchcase on the described touch-pressure switch disappears, and makes described touch-pressure switch reset, and described signal input part puts 1, at this moment described control single chip computer can be read gas meter, flow meter and unusual condition occur, need to produce immediately to interrupt, make that closing the valve signal output terminal is high level, high level amplifies rear drive motor valve-off through amplifying circuit.
Further, in order to realize to open once more after the described motor that removes to drive air-supplying valve is with valve closing the valve of air feed, as shown in Figure 3, described control single chip computer 11 is provided with valve opening signal output terminal 113, and described valve opening signal output terminal 113 is connected with the motor 4 that drives air-supplying valve by described amplifying circuit 12.
The gas meter, flow meter antiwithdrawal device that the utility model embodiment provides, end at described touch-pressure switch is connected with the table lid of gas meter, flow meter, when the other end of described touch-pressure switch is connected with the signal input part of described control single chip computer, air-supplying valve is in opening, when described gas meter, flow meter is disassembled, one end of described trigger switch and the table of described gas meter, flow meter lid disconnect, make the magnitude of voltage of described trigger switch change, and then changed the signal that trigger switch provides for the signal input part of described control single chip computer and changed, make the pass valve signal output terminal output of control single chip computer close valve signal, close valve signal and amplify the motor of controlling described driving air-supplying valve afterwards by amplifying circuit, make described air-supplying valve close, thereby solved owing to damage the problem that gas meter, flow meter causes combustion gas to be revealed.
The gas meter, flow meter antiwithdrawal device that the utility model embodiment provides can be applied in the intelligent gas meter.
The above; it only is embodiment of the present utility model; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the variation that can expect easily or replacement all should be encompassed within the protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of claim.
