Background
The base meter is an original meter for gas flow, and the metering accuracy of the intelligent gas meter is mainly ensured by the base meter. The principle of the base meter of the gas meter is that the gas meter uses the pressure difference of gas in the flowing process of the gas in the meter body as power, and the distribution of the gas flow direction is controlled by the relative positions of the valve seat and the valve cover. The bellows of the gas meter consists of two gas measuring chambers which are the same left and right, and each gas measuring chamber is divided into two identical small measuring chambers by a soft diaphragm. When the dispensed gas enters the four small metering chambers in sequence, the diaphragm is forced to swing freely. The movement of the diaphragm assembly drives a connecting rod mechanism (double crank rocker mechanism) through a rocker to enable the valve cover to rotate, so that the charging and discharging of each metering chamber are sequentially controlled, and the gas meter is enabled to continuously circulate. Meanwhile, the eccentric rotary gear of the connecting rod mechanism drives the mechanical unidirectional counter to count through the transmission of the gear, and finally the displacement of the gas meter is displayed through the counter.
