For example, the development and application of multi-channel plunger valves for slurry bed residue oil hydrogenation units provide a reliable solution for complex fluid control in industrial production. Medical field: Multi-channel valves also have important applications in medical equipment, such as fluid control of medical devices, drug delivery, etc. For example, multi-channel rotary valves have the advantages of ultra-long life, strong reliability, and precise switching, and are suitable for medical instruments, laboratories and other scientific research environments. Environmental protection field: In environmental protection projects such as sewage treatment and waste gas treatment, multi-channel valves can realize the switching and control of different fluids to ensure the smooth progress of the treatment process.

[0003] In terms of control technology, multi-channel valves are constantly introducing advanced control methods and technologies, such as those that can be combined with corresponding intelligent control systems and sensor technologies to achieve automatic control. However, after searching and analyzing, it was found that existing multi-channel valves are not convenient for implementing diversion control, and their complex internal structure leads to high costs. Utility Model Content

[0004] Therefore, in order to solve the above-mentioned shortcomings, the present invention provides a converging multi-channel control valve. For the converging multi-channel control valve described in this application, the position of the channel converging closing portion in the inner cavity is adjusted by controlling the up and down movement of the valve stem, thereby opening and closing the corresponding channels, such as Figure 1 As shown, the valve stem is at the uppermost position at this time, and the horizontal confluence inlet channel is closed. Figure 2 As shown, the valve stem is at the lowest position at this time, and the vertical confluence inlet channel is closed. When the valve stem is controlled in the middle position, two channels can flow at the same time, completing the confluence of the two channel loop media, making the valve confluence control easier, while also reducing the internal structure of the valve and reducing the implementation cost, so that the multi-channel valve can achieve more convenient control and automated operation, achieving the purpose of switching control and confluence of different channels.

[0005] The utility model is realized by constructing a converging multi-channel control valve, characterized in that: the multi-channel valve comprises a valve body, the valve body having a horizontal converging inlet end and a vertical converging inlet end, and a converging outlet end;

[0006] A valve stem capable of moving up and down is provided in the inner cavity of the valve body.

[0007] A horizontal converging inlet channel and a vertical converging inlet channel are provided in the inner cavity of the valve body, which are respectively used to communicate with the horizontal converging inlet end and the vertical converging inlet end; a channel converging closing portion is fixedly provided at the lower end of the valve stem, and the channel converging closing portion is in a shape in which the upper and lower ends are larger than the middle part. The valve stem moves up and down to close the horizontal converging inlet channel and the vertical converging inlet channel through the channel converging closing portion.

[0008] According to the converging multi-channel control valve of the present invention, the feature is that the inner wall of the valve body has a wear-resistant layer.

[0009] According to the utility model, a converging multi-channel control valve is characterized in that the upper end of the valve stem extends out of the valve body, which facilitates the control of the valve stem to achieve its up and down movement in the inner cavity of the valve body.

[0010] According to the utility model, a converging multi-channel control valve is characterized in that the horizontal converging inlet end, the vertical converging inlet end and the converging outlet end are flange structures respectively.

[0011] The utility model has the following advantages: for the converging multi-channel control valve described in this application, the position of the channel converging closing part in the inner cavity is adjusted by controlling the up and down movement of the valve stem, thereby opening and closing the corresponding channels, for example Figure 1 As shown, the valve stem is at the uppermost position at this time, and the horizontal confluence inlet channel is closed. Figure 2 As shown, the valve stem is now at its lowest position, and the vertical converging inlet channel is closed. When the valve stem is controlled in the middle position, both channels can flow simultaneously, completing the converging of the two channel loop media, making valve converging control easier. It also reduces the internal structure of the valve and reduces implementation costs, allowing the multi-channel valve to achieve more convenient control and automated operation, achieving the purpose of switching and converging different channels. In the implementation of the converging multi-channel control valve described in this application, the inner wall of the valve body has a wear-resistant layer that can improve the wear resistance of the valve body cavity. The upper end of the valve stem extends out of the valve body to facilitate the control of the valve stem's up and down movement within the valve body cavity. The horizontal converging inlet end, vertical converging inlet end, and converging outlet end are each flange structures, which facilitates connection to external pipelines during implementation. A slot can also be provided on the horizontal converging inlet end 1A and the vertical converging inlet end 1B, and a filter screen can be installed on the slot to filter the media accordingly.
