Description

Technical Field

[0001] The utility model relates to the field of pressure relief valves, in particular to a pressure relief valve which is easy to install. Background Art

[0002] The pressure relief valve, also known as the safety valve, can automatically open and close according to the working pressure of the system. It is usually installed on the equipment or pipeline of the closed system to protect the safety of the system. When the pressure in the equipment or pipeline exceeds the set pressure of the pressure relief valve, it will automatically open to release the pressure, ensuring that the pressure of the medium in the equipment and pipeline is below the set pressure, protecting the equipment and pipeline and preventing accidents. The most common one is the water heater pressure relief valve, which is a multifunctional water storage type electric water heater safety pressure relief valve, suitable for electric water heaters and air energy water heaters. It also has the functions of a check valve and a pressure relief valve, which can prevent the water entering the electric water heater from flowing back and discharge excess pressure when the pressure in the electric water heater tank is high, so as to ensure the life of the tank and avoid explosion accidents.

[0003] The existing pressure relief valve for water heaters is easy to install and can be installed by oneself when replaced. However, during installation, a wrench is needed to tighten the pressure relief valve and the butt pipe to ensure the sealing of the butt joint. Therefore, a wrench and other installation tools need to be prepared before installation. Therefore, the installation is not convenient enough. In addition, some users do not have suitable tools such as wrenches at home. If they directly tighten it by hand, it is difficult to ensure the tightness of the tightening, which will cause poor sealing of the pressure relief valve connection and easy leakage.

[0004] Therefore, we have made improvements to this and proposed a pressure relief valve that is easy to install. Utility Model Content
