Abstract
The utility model discloses a full mechanical prepaid quantitative water meter, which comprises a water meter shell (1), a water meter shell cover (6) and a reading dial. When users use water, water flow drives a fluid driving wheel (2) to rotate, the fluid driving wheel drives a metering wheel system (3) to rotate and begin to meter, a transitional gear (4) drives a quantitative wheel system (13) to rotate under action of a quantitative spring (8), the quantitative wheel system (13) rotates to drive a rotating shaft (7) to rotate reversely so that a reading dial transitional gear (5) is driven to rotate reversely and the reading dial displays volume of residual water, and when water usage reaches 10% of a preset water volume, a valve spool (11) is cut off and a valve port is turned down, thereby making early warning. Further, water usage is equal to the preset water volume, the valve spool slides downwards along a guide groove in the water meter shell (1) under action of a return spring (14), and the valve port is turned off, so that the water meter stops working. After one working circulation is completed, readings of the water meter are adjusted to the prepaid water volume by working staff of a water supply department if the users need to use water continuously.
