Description

Environment-friendly anti-freezing water meter

Technical Field

The utility model relates to the technical field of metering equipment, in particular to an environment-friendly antifreezing water meter.

Background

Every time winter, the chill comes, the frost crack of the small-caliber resident water meter is extremely easy to cause, and normal water supply is influenced. The antifreeze method adopted for the method comprises the following steps: firstly, wrap up heat preservation material outside water pipe or water gauge, secondly let the tap of family open, keep the trickle state. The two methods have unsatisfactory effects when the temperature is low or poorer effects when the temperature is low because residents do not pay attention to or do not get in place, and the meter reading personnel cannot read the water meter after the water meter is wrapped. To thoroughly solve the problem of freezing prevention, only the water in the volume expansion part of the water meter before freezing is emptied or a storable space is provided.
