Description

Technical Field

[0001] This utility model relates to the field of remote-controlled ball valve technology, specifically a remote-controlled ball valve for nuclear power plants. Background Technology

[0002] A remote-controlled ball valve is a type of ball valve that can be operated via a remote control system. This type of ball valve combines the structure of a traditional ball valve with the advantages of remote control technology, allowing the opening, closing, and regulation of the valve to be achieved via remote signals, eliminating the need for manual on-site operation.

[0003] During the operation of a nuclear power plant, valve control of the piping system is a crucial aspect of ensuring the safe and stable operation of the nuclear reactor. Traditional manual valve operation methods are inconvenient, inefficient, and pose safety risks. Therefore, there is a need to develop a remote-controlled ball valve for nuclear power plants that is easy to use.

[0004] Chinese Patent Publication No. CN216009705U discloses a remote-controlled float valve that facilitates the connection between external pipelines and the remote-controlled float valve, bringing convenience to installers and simplifying the installation process, thereby greatly improving the work efficiency of installers. The remote-controlled float valve includes a main body and a connecting device disposed at the inlet and / or outlet end of the main body for connecting an external pipeline to the main body. The connecting device includes a plug-in ring groove disposed at the inlet and / or outlet end of the main body for inserting the external pipeline, and a support seat disposed at the inlet and / or outlet end of the main body for supporting the external pipeline after it is inserted into the plug-in ring groove.

[0005] The aforementioned prior art involves inserting the external pipe into the insertion ring groove during the installation process of connecting the remote-controlled float valve to the external pipeline. After insertion, the support seat provides support for the external pipe, facilitating the connection between the external pipe and the remote-controlled float valve and providing convenience for subsequent installation by the installers. The lifting device drives and lowers the lifting seat to a predetermined position, where the lifting seat cooperates with the support seat to fix the external pipe in the insertion ring groove, completing the connection between the remote-controlled float valve and the external pipeline. The installation process is simple, simplifies the operation, and greatly improves the work efficiency of the installers. However, the existing device does not have the function of storing electrical energy to provide driving power for the valve body. During use, the remote-controlled float valve will rely entirely on an external power source for driving power. This means that if the external power source fails or is interrupted, the remote-controlled float valve will lose power and cannot work normally, thus affecting the safe operation of the nuclear power plant.
