As the saying goes, there is no small matter of safety, especially the small matter of taking a bath. There are news of water heater explosions every year, which makes people feel a little worried when taking a bath. Today I will teach you a component that is easy to be ignored. It can help you at critical moments, that is, the safety valve of the electric water heater .
safety valve is mainly suitable for electric water heaters and air energy water heaters . It is an safety switch installed near the water inlet of the water heater. Its main function is check and pressure relief . By eliminating the excess pressure on the inner liner of the water heater, the life of the inner liner is ensured and explosion accidents are avoided.
Check function refers to the water in the water heater may flow backward when the water in the water heater is shut down, so the safety valve will act as a check function in time to keep the inner liner pressure at a stable value.
Pressure relief function refers to the reaction action when the inner liner of the water heater is too high. For example, when the inner liner is constantly heated, the inner liner pressure is too high, and the excess pressure is discharged through the safety valve, so that the inner liner will not have an explosion accident.
combines the safety valve with check and pressure relief functions. It is really important, so the safety valve of the electric water heater must be checked regularly!
If there is a slight leakage in your safety valve, it is normal. This is when the pressure of the inner liner exceeds the threshold, the safety valve will be activated, and water will flow out of the safety valve; but if it is continuous dripping, it is abnormal. It is very likely that it is caused by the excessive water pressure of the water heater or the damage to the safety pressure relief valve, so it must be taken seriously.
In addition, if your water heater has been used for a long time, there are rust stains and yellowing in the inner liner, poor sealing will also lead to leakage of the safety valve.
So finally I would like to remind you that the safe use period of electric water heaters is 8 year. When it is time to retire, you must regularly inspect and replace them to ensure the safety of bathing. The safety valve of the water heater is really important. It can help you at critical moments. It is safe and no small matter, so the safety valve of the electric water heater must be checked regularly!
