Embodiment Construction
[0036] The present invention will be further elaborated below in conjunction with the accompanying drawings.
[0037] refer to figure 1 As shown, one embodiment of the present invention is a cut-off membrane gas meter, which includes a base meter body, the base meter body is provided with a gas inlet and a gas outlet, and a shut-off valve is installed on the gas inlet. The gas meter also includes a signal acquisition and processing circuit and a cut-off membrane gas meter terminal microcomputer controller. The signal acquisition and processing circuit is connected to the cut-off membrane gas meter terminal microcomputer controller. The acquisition end of the signal acquisition and processing circuit is placed At any position of the gas channel inside the base meter body, the shut-off valve is connected to the microcomputer controller of the shut-off membrane gas meter terminal through the shut-off valve control circuit;
[0038] The function of the above-mentioned gas meter s...

The invention discloses a shut-off diaphragm gas meter, and belongs to a gas meter. The shut-off diaphragm gas meter comprises a basic meter, a signal acquisition processing circuit and a microcomputer controller of a shut-off diaphragm gas meter terminal. A gas inlet and a gas outlet are formed in the basic meter, a shut-off valve is mounted on the gas inlet, the signal acquisition processing circuit is connected into the microcomputer controller of the shut-off diaphragm gas meter terminal, and the shut-off valve is connected into the microcomputer controller of the cut-off diaphragm gas meter terminal by a shut-off valve control circuit. The shut-off diaphragm gas meter has the advantages that the quantity of gas which flows through the basic meter is acquired by the signal acquisition processing circuit in real time and is timely transmitted to the microcomputer controller of the shut-off diaphragm gas meter terminal, the shut-off valve on the basic meter can be timely shut off when abnormal states such as low output flow leakage, abnormal high output flow and excessively long service time of the basic meter are detected, a warning effect can be realized by the aid of a liquid crystal display and a buzzer, accordingly, phenomena of combustion or explosion due to excessive gas leakage can be prevented, and the life and property safety of people can be protected.
Description
technical field [0001] The invention relates to a gas meter, more specifically, the invention mainly relates to a cut-off membrane gas meter. Background technique [0002] With the continuous improvement of the construction of gas projects in my country, the application range of gas has been greatly expanded, and a wider range of popularization has been achieved. However, there is no effective and reliable implementation method to deal with the abnormal state of the gas. When the gas is in an abnormal state during use, leakage, fire, explosion, etc. may occur, which is not conducive to the natural gas safety management of the gas company, and it is also harmful to people's lives and Property security brings great hidden dangers. [0003] Because the general diaphragm gas meter does not have the function of effectively collecting abnormal state information and pipeline safety cut-off, during use, when there are problems such as gas leakage of gas equipment and excessive gas co...
