Operating Principle:
The gas is alternately entered into the metering chamber through the distribution valve, and at the same time, the flexible diaphragm in the metering chamber is pushed to reciprocate, and after being filled with gas, it is discharged to the air outlet, and the circulation process of the inflation and exhaust is converted into a corresponding volume by the conversion mechanism, and the transmission is transmitted to the counter.
