Description

Technical Field

[0001] This utility model relates to the field of valve technology, specifically a novel one-to-many pipeline valve. Background Technology

[0002] Since the early 20th century, pigging technology has emerged in various forms. Today, pigging technology is used in a wide range of sectors, industries, and applications that handle liquids and powders to recover liquids and powders from pipelines, reduce waste, and improve the efficiency of manufacturing and production processes. The main purpose of pigging is to remove or recover residual product left in the pipeline after being transported from one location to another in a production line. In its simplest form, a pigging system consists of a flexible ejector, slightly larger in diameter than the pipeline to be pigged, which pushes even the product being processed through the pipeline to remove or recover high-value products.

[0003] Valves are an important component of pipeline cleaning systems. Products in pipelines mainly use valves to select the flow direction. Most existing valves are single-way or double-way valves. When completing the task of connecting a single source to multiple targets or multiple sources to a single target, multiple valves are required. Traditional multi-valve groups require multiple independent actuators, resulting in higher equipment costs and more complicated construction.

[0004] Therefore, this utility model provides a novel one-to-many pipeline valve. Utility Model Content

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0020] Please see Figures 1 to 3 This utility model provides a technical solution: a novel one-to-many pipeline valve, including a valve body 6 and a valve core 1. The valve core 1 is rotatably fitted inside the valve body 6. A first sealing structure is installed between the valve body 6 and the valve core 1. A fixing cover 20 and a first fixing plate 7 are respectively fixed on the upper and lower sides of the valve body 6. A second sealing structure is installed between the first fixing plate 7 and the valve core 1 and the valve body 6. A third sealing structure is installed between the fixing cover 20 and the valve core 1 and the valve body 6. A drive connection structure is installed on the valve core 1. Multiple first connecting structures are installed on the periphery of the valve body 6. The first connecting structures correspond to the first sealing structures. A second connecting structure is installed on the first fixing plate 7. A through groove 21 is opened inside the valve core 1. The through groove 21 corresponds to the second connecting structure and the first connecting structure.

[0021] In this embodiment, the drive connection structure includes a drive block 3, a drive rod 2 is fixed on the drive block 3, and a snap-fit ​​fixing structure is installed between the drive block 3 and the valve core 1. The snap-fit ​​fixing structure includes multiple snap blocks 4 fixed on the drive block 3, and multiple snap slots 5 are opened on the valve core 1, with the snap slots 5 corresponding to the snap blocks 4.

[0022] Specifically, the valve core 1 is connected to the pneumatic actuator above via the drive rod 2. The control system issues commands to the pneumatic actuator to control the rotation of the valve core 1, so that the through groove 21 is connected to one of the second connectors 8, thereby controlling the flow direction of the product in the pipeline.

[0023] The second connecting structure includes a first connector 10 fixed on the first fixing plate 7. The first connector 10 is connected to the through groove 21. Multiple first fixing bolts 11 are fixed between the first fixing plate 7 and the valve body 6. The product enters the through groove 21 through the first connector 10 and is then sent out through the second connector 8.

[0024] The first connecting structure includes four second fixing plates 9 fixed around the valve body 6, and a second connector 8 fixed on the second fixing plate 9. The second connector 8 is connected to the through groove 21, and a plurality of second fixing bolts 12 are fixed between the second fixing plate 9 and the valve body 6.

[0025] Specifically, rotating the valve core 1 causes it to rotate within the valve body 6, thereby driving the through groove 21 to rotate and connecting it to different second connectors 8, thus changing the direction of product flow. This allows the valve to input and output in a one-to-many or many-to-one manner, greatly improving the flexibility of the device.

[0026] The first sealing structure includes a first sealing ring 14 and a first sealing gasket 15, the second sealing structure includes a second sealing ring 16 and a second sealing gasket 17, the third sealing structure includes a third sealing ring 18 and a third sealing gasket 19, and a plurality of third fixing bolts 13 are fixed between the fixed cover 20 and the valve body 6.

[0027] Specifically, the sealing effect between the valve core 1, valve body 6, fixed cover 20, second fixed plate 9 and first fixed plate 7 can be ensured by the first sealing ring 14, the first sealing gasket 15, the second sealing ring 16, the second sealing gasket 17, the third sealing ring 18 and the third sealing gasket 19, so as to prevent air leakage, water leakage and other situations.

[0028] Workflow: Connect the first connector 10 and the second connector 8 to the pipeline, and connect the drive rod 2 to the pneumatic actuator above. The product can be input through the first connector 10 and output through the second connector 8, or input through the second connector 8 and output through the first connector 10. The pneumatic actuator can drive the valve core 1 to rotate, causing the through groove 21 to rotate, thereby connecting the through groove 21 to another second connector 8, which can change the product flow direction. This allows the valve to be used for one-to-many input or many-to-one output, expanding the applicability of the device.

[0029] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
