Abstract

The preset character wheel return-to-zero detecting output control device includes a character wheel counter combination with raised points, a detecting board rotating around the shaft, a detecting output rod with controlling slot, a detecting output rod releasing spring, a detecting board resetting spring, a preset detecting wheel, a preset detecting wheel photo electronic sensor, a presetting or composite meshing gear, a resetting input wheel, a presetting input wheel, and a presetting drive motor. The present invention is used in passive pre-paid water meter and gas meter, and possesses precise measuring, resetting, light load presetting, reliable releasing, controlling valve and other functions.

Description

technical field [0001] The invention relates to a prepayment control device for a water meter and a gas meter without working power supply, in particular to a device for controlling the closing of a valve by detecting whether the salient points on the character wheel counter are consistent. Background technique [0002] "ZL00254209 Passive Prepaid Water Meter" patent, "ZL00254210 Passive Prepaid Gas Meter" patent, "ZL00254211 Controller Passive Prepaid Electric Meter" patent, "ZL00258037 Inverted Counter Prepaid Electric Water Gas Meter Control Device" The patents all use a character wheel counter with a groove, and use a mechanical detection device to sense whether all of them have entered the groove to determine that the remaining value is all 0, and drive the valve closing device to achieve prepaid control without working power. There is a serious technical problem in these schemes, that is, the detection device has to act on the character wheel counter group to sense whe...
