Electric water heaters are the most common types of water heaters in life, and safety valves are one of the important accessories for electric water heaters. Many people do not understand them. What is the role of electric water heater safety valves ? What is the principle of the electric water heater safety valve? Let's take a look at the decoration home decoration network Xiaobian. What is the role of the electric water heater safety valve? The electric water heater safety valve is suitable for the electric water heater and the air energy water heater. At the same time, it has the function of the check valve and the pressure relief valve, which can prevent the water flowing into the electric water heater and prevent the pressure of the electric water heater from being high, excreting excess pressure to ensure The life of the liner and the avoidance of a blast accident occur . It is a multi-function water storage type electric water heater safety relief valve. The valve body tee is divided into a water inlet chamber, a water outlet chamber and a safety chamber, and the safety chamber is provided with a drainage hole. Place the check valve core and the outer adjustment spring in the water outlet cavity, and define it with the adjustment limit piece. Place the elastic pad, safety valve core and drain rod, safety pressure adjustment spring in the safety cavity, and adjust the cover to screw in the safety through the drain rod. There is a protective cover on the cavity and the outside, and a drain ear is connected at the end of the drain rod, the drain ear is fastened with a protective buckle, and the protection buckle is fixed on the drain hole seat by the drain pipe joint. It has the functions of backflow backflow, safe pressure relief, drainage cleaning, etc., and it is convenient to adjust. The safety valve should be installed vertically and installed at the gas phase interface of the vessel or pipe. The principle of electric water heater safety valve: Safety valves are safety devices designed to prevent pressure equipment and containers from rupturing due to pressure build-up or pressure inside the container. The safety valve is a safety device widely used in pressure systems such as pressure vessels, boilers and pressure pipes to ensure the safe operation of the pressure system. When the pressure of the container exceeds the design specification, the safety valve is automatically opened to discharge the high pressure inside the gas reducer to prevent damage to the container or pipeline. When the pressure in the container drops to the normal operating pressure, it is automatically closed to avoid exhausting all the gas due to overpressure of the container, resulting in waste and production interruption. The safety valve is mainly composed of a valve seat, a valve disc ( spool ) and a loading mechanism. The valve seat is integral with the valve body, and is assembled with the valve body to communicate with the device. The valve flap is often attached with a valve stem that snaps onto the valve seat. Above the valve flap is the loading mechanism, and the size of the load can be adjusted. When the pressure in the device is within a certain working pressure range, the force acting on the valve disc by the internal medium is less than the force exerted on the valve by the loading mechanism, and the difference between the two constitutes the sealing force between the valve flap and the valve seat. The valve flap is pressed against the seat and the media of the device cannot be discharged. When the pressure in the device exceeds the specified working pressure and reaches the opening pressure of the safety valve, the force exerted by the internal medium on the valve is greater than the force exerted by the loading mechanism on the valve, so that the valve flap leaves the valve seat and the safety valve opens. The medium inside is discharged through the valve seat. If the displacement of the safety valve is greater than the safety relief of the equipment, the pressure inside the equipment gradually decreases, and after a short period of exhaust, the pressure drops back to the normal working pressure. At this time, the internal pressure acts on the valve flap and the force applied to the valve is smaller than the force applied by the loading mechanism. The valve flap is pressed against the valve seat, the medium stops discharging, and the device maintains normal working pressure to continue to operate. Suitable for chemical, environmental, food and other industries. The above is what is the role of the electric water heater safety valve brought by Xiaobian?
