Description

Technical Field

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

[0002] Currently, the combined structure of three-way ball valves on the market has not completely solved the problem of asynchronous switching of parallel three channels. At the same time, because there is no rotation limit structure (such as mechanical limit block) on the valve stem or actuator, the rotation angle of the ball cannot be accurately controlled, resulting in inaccurate switching position and cross-flow of media.

[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 ball 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 ball valve.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A dual-valve linkage structure for a combined three-way ball valve includes a left positioning plate and a right positioning plate. A connecting shaft connects the left and right positioning plates, forming a concave structure between the connecting shaft, the left positioning plate, and the right positioning plate. A left three-way ball valve is connected to the left positioning plate within the concave structure, and a right three-way ball valve is connected to the right positioning plate. A left valve stem and a right valve stem are respectively connected to the left and right three-way ball valves. The left and right valve stems are opposite to each other and synchronously connected by a rotatable synchronous connecting rod, thereby enabling the left and right three-way ball valves to form a dual-valve linkage structure.

[0006] Preferably, in the dual-valve linkage structure of the combined three-way ball valve, a handle is connected to the synchronous connecting rod.

[0007] Preferably, in the dual-valve linkage structure of the combined three-way ball valve, the left three-way ball valve and the right three-way ball valve are arranged in parallel and side by side.

[0008] Preferably, in the dual-valve linkage structure of the combined three-way ball valve, the left valve stem and the right valve stem are connected and fixed to the synchronous connecting rod by fastening screws.

[0009] Preferably, in the dual-valve linkage structure of the combined three-way ball valve, a positioning block for limiting the rotation angle is connected to the left valve stem.

[0010] Preferably, in the dual-valve linkage structure of the combined three-way ball valve, a positioning block for limiting the rotation angle is connected to the right valve stem.

[0011] Preferably, in the dual-valve linkage structure of the combined three-way ball valve, the positioning plate and the connecting shaft are connected by studs.

[0012] Preferably, in the dual-valve linkage structure of the combined three-way ball valve, the rotation angle of the synchronous connecting rod is between 0° and 90°.

[0013] Preferably, in the dual-valve linkage structure of the combined three-way ball valve, both the left three-way ball valve and the right three-way ball valve are connected to the corresponding positioning plate by fastening bolts.

[0014] By means of the above solution, this utility model has at least the following advantages: This utility model adopts a dual-valve linkage structure to cooperate with complex pipelines and achieve better flow. Secondly, the dual-valve linkage structure achieves synchronization through a mechanical rigid connection. When rotating 90°, it synchronously drives the two balls to rotate, realizing the synchronous opening and closing or flow direction switching of two parallel pipelines, achieving a better linkage effect. The integral valve body structure reduces the risk of external leakage, and the size is compatible with traditional three-way ball valves, making it easy to replace, disassemble, and maintain.

[0015] 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.

It should be understood that the following drawings only show some embodiments of this utility model and should not be regarded as a limitation on the scope.

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0019] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0020] Example like Figure 1 , Figure 2 and Figure 3 As shown, a dual-valve linkage structure of a combined three-way ball valve includes a left positioning plate 1 and a right positioning plate 6. A connecting shaft 3 connects the left positioning plate 1 and the right positioning plate 6. The connecting shaft 3, the left positioning plate 1, and the right positioning plate 6 form a concave structure. A left three-way ball valve 2 is connected to the left positioning plate 1 within the concave structure, and a right three-way ball valve 7 is connected to the right positioning plate 6. The left three-way ball valve 2 and the right three-way ball valve 7 are parallel and arranged side by side. A left valve stem 8 and a right valve stem 9 are respectively connected to the left three-way ball valve 2 and the right three-way ball valve 7. The left valve stem 8 and the right valve stem 9 are opposite each other and synchronously connected by a rotatable synchronous connecting rod 10. The synchronous connecting rod 10 enables the left three-way ball valve 2 and the right three-way ball valve 7 to form a dual-valve linkage structure.

[0021] The synchronous connecting rod 10 described in this utility model is connected to a handle 4, which facilitates the operation of the operator.

[0022] In this invention, the left valve stem 8 and right valve stem 9 are connected and fixed to the synchronous connecting rod 10 by fastening screws; the left three-way ball valve 2 and right three-way ball valve 7 are both connected to the corresponding positioning plates by fastening bolts; the positioning plate 1 and the connecting shaft 3 are connected by studs. This allows for quick installation, disassembly, and replacement.

[0023] Example 1 Based on the embodiment, the rotation angle of the ball can be precisely controlled to ensure accurate switching position and avoid media crossflow. The left valve stem 8 is connected to a positioning block 5 for limiting the rotation angle.

[0024] In actual operation, the rotation angle of the synchronous connecting rod 10 is between 0° and 90°, that is, 0° is the closed state and 90° is the open state. The rotation of the synchronous connecting rod is driven by the handle. After the synchronous connecting rod rotates, it will drive the rotation of the left valve stem and the right valve stem connected to it synchronously, thereby realizing the synchronous opening and closing or flow direction switching of the left and right three-way ball valves. During this process, the positioning block will be fixed at the specified angle, that is, at 90°, so that the angle after opening can be precisely controlled.

[0025] A positioning block 5 is connected to the right valve stem 9 to limit the rotation angle. The positioning block 5 can be installed on the left valve stem, the right valve stem, or both; there are no restrictions on its installation position. Figure 1 As shown, this utility model is only installed on the left valve stem.

[0026] For specific installation, the positioning plate and connecting shaft are installed using studs. Then, the two three-way ball valves are connected using the handle assembly, and both ends are locked to the left and right valve stems with fastening screws. Finally, the two combined three-way ball valves are installed on the positioning plate.

[0027] The working principle of this utility model is as follows: In actual operation, the handle drives the rotation of the synchronous connecting rod. After the synchronous connecting rod rotates, it will drive the rotation of the left valve stem and the right valve stem that are connected to it synchronously, thereby realizing the synchronous opening and closing or flow direction switching of the left and right three-way ball valves.

[0028] 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.

[0029] 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.

[0030] 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.

[0031] 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.

[0032] 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.
