Abstract
The invention discloses a gas meter capable of automatically cutting off water inflow. The gas meter comprises a basic meter body, wherein a floating ball, an upper valve device and a lower valve device are arranged in the basic meter body. The upper valve device is in the shape of a small-end-up horn mouth and is connected to a gas inlet of the basic meter body in a sealed mode. The lower valve device is in the shape of a small-end-down horn mouth and is fixedly connected to the end, opposite to the gas inlet, of the basic meter body. The floating ball is arranged between the upper valve device and the lower valve device. The horn mouth of the upper valve device and the horn mouth of the lower valve device are symmetrical about the horizontal line.
