Abstract

The invention belongs to the technical field of instruments and meters, and discloses a wet-type water meter comprising a meter shell and cover glass on the top of the meter shell, wherein the cover glass is prepared from the following raw materials: cryolite, potassium permanganate, flux, zinc oxide, antimony oxide, kaolin, fluorite, calcite, boron oxide, soda ash, and quartz sand. The cover glass of the wet-type water meter in the invention is reasonable in compatibility, and such indices as rupture strength, compression resistance, and light transmittance are all greatly improved.

Description

technical field [0001] The invention belongs to the technical field of instruments and meters, and in particular relates to a wet water meter. 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 freeze and expand, which will pr...
