1. Installation steps of electric water heater safety valve - STEP 1

There is an arrow on the water heater safety valve, which is the direction of adding water to the water heater, and it is a one-way valve. Remember not to install in reverse. The upper end is connected to the water tank, and the lower end is connected to the mixing valve, both of which are positive buckles. The pressure relief outlet cannot be blocked. When the water temperature is high and the pressure is large, it must be used to relieve the pressure to ensure safety. When the water pressure is too high, the safety valve of the water heater will automatically open to reduce the water pressure in the water tank and keep the water heater in a safe state.

when the pressure of the container exceeds the design requirements, the safety valve will automatically open, and the exhaust gas will reduce the excessive pressure in the device to prevent damage to the container or pipeline. And when the pressure in the container drops to the normal operating pressure, it automatically shuts down to avoid all the gas being discharged due to the overpressure of the container, thus causing waste and production interruption. The safety valve is mainly composed of three parts: valve seat, valve disc (valve core) and loading mechanism.
