Safety valve with anti-blocking structure for electric water heater

Abstract

The invention discloses a safety valve with an anti-blocking structure for an electric water heater. The safety valve comprises a check valve. An external thread is integrally formed in the outer surface of the bottom end of the check valve. A pressure relief valve is welded to the right side of the check valve. A pressure discharge pipe and a fixed pile are integrally connected with the lower surface of the pressure relief valve. The fixed pile is arranged on the right side of the pressure discharge pipe. A safety handle is arranged on the right side of the fixed pile. An inner cylinder is connected with inner side of the check valve through threads. A connecting rod and a first check ring are welded to the inner side of the inner cylinder. The first check ring is arranged on the upper side of the connecting rod. A connecting sleeve is welded to the inner side of the connecting rod in a penetrating mode. A first valve element is arranged on the inner side of the connecting sleeve in apenetrating mode. A water wheel is arranged on the outer surface of the first valve element in a sleeving mode. A cleaning rod is integrally connected with the outer surface of the water wheel. The safety valve has the anti-blocking structure, the limit to the safety handle can be conveniently removed, and the operation convenience is improved.

Description

technical field [0001] The invention relates to the technical field of safety valves, in particular to a safety valve for an electric water heater with an anti-blocking structure. Background technique [0002] When the electric water heater is working, if the temperature inside the heating cylinder is too high, hot pressure will be generated. If the hot pressure is too high, there will be certain safety hazards. The safety valve can automatically discharge the pressure to ensure the safety of the electric water heater. [0003] When the existing safety valve is used in an electric water heater, because the electric water heater is heated with tap water, some tap water with poor water quality will produce scale after being heated by the electric water heater, and some fine scale will fall into the safety valve under the influence of the heat flow in the water. In the valve, the safety valve is blocked, which affects the normal use of the safety valve, and the existing safety ...
