Description

Technical Field

[0001] This utility model relates to a dual-valve linkage structure of a combined three-way valve. Background Technology

[0002] Currently, complex fluid distribution systems often require multiple three-way valves to work together to achieve flexible switching and diversion of fluid between different pipelines. However, most of these three-way valves are currently controlled independently. This approach is not only complex and inefficient, but also makes it difficult to ensure the coordination of valve actions, easily leading to uneven fluid distribution and even pipeline pressure imbalances. Furthermore, independent control structures occupy a large amount of space, increasing the difficulty of equipment layout and installation.

[0003] In view of the above-mentioned shortcomings, the designer actively researched and innovated in order to create a new type of combined three-way valve with a dual-valve linkage structure, making it more valuable for industrial applications. Utility Model Content

[0004] To solve the above-mentioned technical problems, the purpose of this utility model is to provide a dual-valve linkage structure for a combined three-way valve.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A dual-valve linkage structure of a combined three-way valve includes a first three-way valve and a second three-way valve with the same structure. The first three-way valve and the second three-way valve are respectively connected to a first valve disc and a second valve disc. A first valve stem and a second valve stem are respectively connected to the first valve disc and the second valve disc. A handwheel is connected to both the first valve stem and the second three-way valve. The first three-way valve and the second three-way valve are connected to each other through a connecting member and form a parallel structure. A first gear and a second gear are respectively connected to the first valve stem and the second valve stem, which rotate with their respective valve stems. A synchronization chain is connected between the first gear and the second gear to realize the synchronous opening and closing of the first three-way valve and the second three-way valve.

[0007] Preferably, in the dual-valve linkage structure of the combined three-way valve, the first three-way valve and the second three-way valve are connected in parallel through a connector, gear and synchronous chain to form a dual-valve linkage structure.

[0008] Preferably, in the dual-valve linkage structure of the combined three-way valve, the first three-way valve, the second three-way valve, and the connecting parts constitute a combined integrated module.

[0009] Preferably, in the dual-valve linkage structure of the combined three-way valve, the synchronization chain is an adjustable synchronization chain.

[0010] Preferably, in the dual-valve linkage structure of the combined three-way valve, the connecting component is a two-way pipe or a three-way pipe.

[0011] By means of the above solution, this utility model has at least the following advantages:

[0012] This utility model adopts a dual-valve linkage structure to better facilitate the flow of complex pipelines. Secondly, the dual-valve linkage structure achieves synchronization through gear and chain connection, synchronously driving the opening and closing of the two valve discs to realize the synchronous opening and closing or flow direction switching of two parallel pipelines, achieving a better linkage effect. The parallel combined valve body structure reduces the risk of external leakage. Compared with the traditional control method of multiple independent three-way valves, it greatly saves space, facilitates equipment layout, installation and maintenance, and reduces the overall cost of the system.

[0013] The above description is only an overview of the technical solution of this utility model. In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, the preferred embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0020] Example

[0021] like Figure 1 , Figure 2 and Figure 3 As shown, a dual-valve linkage structure of a combined three-way valve includes a first three-way valve 1 and a second three-way valve 6 with the same structure. The first three-way valve 1 and the second three-way valve 6 are respectively connected to a first valve disc and a second valve disc. The first valve disc and the second valve disc are respectively connected to a first valve stem 8 and a second valve stem 9. A handwheel 3 is connected to both the first valve stem 8 and the second valve stem 9. The first three-way valve 1 and the second three-way valve 6 are connected through a connecting member 4 and the first three-way valve 1 and the second three-way valve 6 form a parallel structure. The first valve stem 8 and the second valve stem 9 are respectively connected to a first gear 2 and a second gear 7 that rotate with their respective valve stems. A synchronization chain 5 is connected between the first gear 2 and the second gear 7 to realize the synchronous opening and closing of the first three-way valve 1 and the second three-way valve 6.

[0022] Example 1

[0023] Based on the embodiment, the first three-way valve 1 and the second three-way valve 6 form a parallel dual-valve linkage structure through the connector 4, gears and synchronous chains. Combined with the first three-way valve 1, the second three-way valve 6 and the connector 4, a combined integrated module can be formed, which can realize the dual-valve linkage structure and also realize synchronous opening and closing, realize the synchronous opening and closing or flow direction switching of two parallel pipelines, and achieve a better linkage effect.

[0024] Meanwhile, the integrated module approach can reduce the risk of external leakage, and compared with the traditional control method of multiple independent three-way valves, it greatly saves space and facilitates equipment layout.

[0025] In accordance with Embodiment 1 and Embodiment 2, the synchronization chain 5 described in this invention is an adjustable synchronization chain. The synchronization chain can be adjusted to accommodate different gear spacings, achieving a reasonable and suitable distance to ensure synchronization.

[0026] The connector 4 described in this utility model is a two-way pipe or a three-way pipe. The connector can be assembled as needed to install two three-way valves.

[0027] The specific installation is as follows: First, install the two three-way valves using the connecting assembly, then connect the gears below the handwheels of the two three-way valves with a chain, and finally install the two combined three-way valves on the pipeline.

[0028] The working principle of this utility model is as follows:

[0029] In actual operation, simply rotate one of the handwheels of the first or second three-way valve. The rotation of the handwheel drives the corresponding gear to engage, and the other three-way valve operates synchronously under the drive of the synchronous chain.

[0030] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0031] In the description of this application, it should be noted that the terms "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product is in use. They are used only for the convenience of describing this application and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application. Furthermore, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0032] Furthermore, terms such as "horizontal" and "vertical" do not imply that components must be absolutely horizontal or vertical, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0033] In the description of this application, it should also be noted that, unless otherwise expressly specified and limited, the terms "set up," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0034] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
