Description

technical field [0001] The invention relates to a safety valve for an electric water heater, in particular to a safety valve for an electric water heater with end face sealing. Background technique [0002] The existing electric water heater safety valve has partly adopted the end face sealing structure. When the safety valve of this structure is connected with the water heater, it is sealed by a flat gasket, and the sealing effect is better. However, its internal leakage structure uses a copper insert with a boss to connect the safety valve through threads. Due to the complicated production process of the copper internal leakage insert with a boss, there are problems such as difficult quality assurance, heavy weight, and high cost. , In addition, the copper insert and the safety valve are connected by threads, the assembly method is inefficient, and there may be hidden dangers such as improper installation. Contents of the invention [0003] The object of the present inv...
