Abstract

The invention relates to a relief valve for electric water heater. It includes valve body, internal relief valve seat, relainer ring, spring, internal relief valve core, external relief valve core, sealing washer, drawbar, regulating pressure cover regulating nut and screw rod, etc. Said invention also provides their connection mode and the concrete structure of the above-mentioned every component.

Description

technical field [0001] The present invention pertains to spring loaded safety valves. Background technique [0002] The safety valve on the electric water heater consists of two pressure relief parts, the internal pressure relief and the external pressure relief. The external pressure release can ensure that the pressure of the inner tank of the electric water heater is not higher than the safe setting value, and the internal pressure release can adjust the uniformity of the inner tank pressure of the water inlet pressure. When the inner tank pressure exceeds a certain value, a part of the inner tank will Water returns to the water pipe through the internal pressure relief channel, and when the water is cut off, it can ensure that the water in the inner tank remains at a certain amount, so that the electric water heater will not be empty due to water shortage. The pressure relief spool (such as image 3 (shown) is provided with a diameter-reducing groove 30, and the valve c...
