Abstract

The invention belongs to the technical field of instruments and meters and discloses an anti-freezing wet water meter with meter glass, comprising a meter shell, meter glass and a meter enclosure, and the meter glass is fixedly clamped between the meter enclosure and the top of the meter shell; the anti-freezing wet water meter is characterized in that the meter glass is produced via the steps of 1) preparing a cosolvent; 2) crushing, and grinding; 3) stirring and grinding; 4) casting, annealing and cooling; 5) pickling, boiling and cooling. The anti-freezing wet water meter is suitable for use in extreme cold weather; the meter glass has good anti-freezing property and rarely breaks.

Description

technical field [0001] The invention belongs to the technical field of instruments and meters, and in particular relates to an antifreeze wet water meter with a watch glass. Background technique [0002] A wet water meter is a water meter with a counter immersed in water. The glass on the watch is subjected to water pressure. The transmission of the sensor and the counter is a gear linkage. The existing wet water meter is mainly composed of a watch case, a metering part installed in the watch case, an impeller part, and a master-slave transmission magnet. The chamber of the component and the impeller component are installed in the water flow chamber. After all the components are installed, the space in the watch case is basically fixed, that is, its volume remains unchanged. This constant volume is convenient for water meter measurement and installation, but When the outside temperature is lower than zero degrees Celsius, the accumulated water in the watch case is easy to f...
