Description

Technical Field

[0001] This utility model relates to the field of safety valve technology, specifically to a corrosion-resistant mini safety valve. Background Technology

[0002] In existing technology, when an electric water heater is powered on and water is flowing, if the water pressure in the inner tank becomes too high during the electric heating process, some water is discharged through an internal drain. When the pressure in the inner tank exceeds the external drain pressure, water drips from the external drain to release pressure. It is normal for water to drip during the heating process; if no water drips, it indicates that the water pressure is within the rated pressure range set by the safety valve during heating. Based on this, the applicant has made corresponding design improvements and submitted an application for a corrosion-resistant mini safety valve. Utility Model Content
