Description

Technical Field

[0001] This utility model relates to the field of switching valve technology, and in particular to a split-type valve core switching valve. Background Technology

[0002] Switching valves are key components in industrial pipelines used to change the direction of media flow. Three-way switching valves are a common type, controlling fluid direction through three ports. These valves typically consist of a valve body, valve core, and drive mechanism. During operation, rotating or translating the valve core switches the medium between two pathways. For example, in heating systems, a three-way valve can switch hot water to different radiator groups as needed, or in chemical production, it can direct raw materials to different reaction tanks. Compared to complex multi-way valves, three-way valves are more compact, have a lower failure rate, and are particularly suitable for scenarios requiring frequent flow direction switching. Many newer models are now equipped with electric or pneumatic control modules, enabling remote adjustment, retaining the reliability of mechanical valves while improving automation levels.

[0003] Patent document CN217898903U discloses a split-type three-way ball valve, including a valve body, a three-way ball, a valve stem, and a handle. One end of the valve stem extends into the valve cavity of the valve body and connects to the three-way ball valve, while the other end is placed outside the valve body and connects to the handle. The valve body has three medium inlets and outlets communicating with the valve cavity. A bottom cover is provided at the bottom of the valve body, which is connected to the valve body by bolts. The end face of the bottom cover that mates with the valve body has two raised ridges, and the valve body has grooves for the aforementioned raised ridges to be inserted. This utility model, by providing a detachable bottom cover at the bottom of the valve body, allows for cleaning of the inside of the ball valve by removing the bottom cover, preventing valve blockage and improving service life. Since the bottom cover is located at the bottom, its removal does not affect the various components of the ball valve, allowing for convenient and quick individual disassembly and assembly.

[0004] As in the prior art of the aforementioned patent, the split-type three-way valve uses a ball valve core. However, this type of ball valve cannot control the water flow of each channel during use. Furthermore, the disassembly of the ball valve is relatively complicated, and only the bottom shell can be disassembled, making it impossible to thoroughly clean the valve core inside the valve body. Utility Model Content

[0005] Purpose of the utility model: The purpose of this utility model is to provide a split-type valve core switching valve to solve the above-mentioned shortcomings in the prior art.

[0006] Technical solution: A split-type valve core switching valve includes a connecting pipe, an input end connected to the top of the connecting pipe, and a first output end and a second output end fixedly installed at the bottom of the connecting pipe. The first output end and the second output end are respectively located on both sides of the input end. A valve core is slidably installed inside the connecting pipe. The valve core is cylindrical and tightly attached to the inner wall of the connecting pipe. A sealing assembly is provided at one end of the connecting pipe. An adjusting rod is provided on the sealing assembly. One end of the adjusting rod is connected to the valve core, and a rotating disk is fixedly installed at the other end of the adjusting rod.

[0007] As a further description of the above technical solution: the width of the valve core is greater than the inner diameter of the input end.

[0008] As a further description of the above technical solution: the sealing assembly includes a hexagonal connector and a sealing nut fixedly installed on the hexagonal connector, and the sealing nut is threadedly connected to one end of the connecting pipe.

[0009] As a further description of the above technical solution: the adjusting rod is provided with a second threaded section, the valve core is threadedly connected to the adjusting rod through the second threaded section, and the adjusting rod is set to rotate clockwise in the screwing direction.

[0010] As a further description of the above technical solution: the adjusting rod is provided with a first threaded section, which is threadedly connected to the inner hole of the sealing nut and the hexagonal connector, and the adjusting rod is set to rotate clockwise as the screw-in direction.

[0011] As a further description of the above technical solution: the adjusting rod is provided with a through groove, which is located between the first threaded section and the second threaded section.

[0012] As a further description of the above technical solution: multiple scraping teeth are provided on both circular end faces of the valve core, and the multiple scraping teeth are arranged in a ring array with the center line of the valve core as the axis.

[0013] As a further description of the above technical solution: a wear-resistant rubber layer is provided at the contact points between the multiple scraping teeth and the inner wall of the connecting pipe.

[0014] Beneficial effects: The initial position of the valve core is between the input end and the second output end. At this time, water can enter the connecting pipe through the input end. With the valve core blocking the flow, it can be output through the first output end. When it is necessary to adjust the flow direction, the valve core is pushed towards the first output end by rotating the adjusting rod. When the valve core is below the input end, the input end can be completely blocked. At this time, no water will flow from either the first or second output end. When the valve core moves further towards the first output end, the water flowing in from the input end can flow out through the second output end, thereby realizing the switching from the first output end to the second output end. Since the width of the valve core is larger than the inner diameter of the input end when the valve core moves below the input end, the flow rate can be controlled at each output end while maintaining a constant flow rate.

[0023] To make the technical solution of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] Reference Figure 1-6A split-type valve core switching valve includes a connecting pipe 1. An input end 2 is connected to the top of the connecting pipe 1, and a first output end 3 and a second output end 4 are fixedly installed at the bottom of the connecting pipe 1. The first output end 3 and the second output end 4 are respectively located on both sides of the input end 2. A valve core 11 is slidably installed inside the connecting pipe 1. The valve core 11 is cylindrical and tightly attached to the inner wall of the connecting pipe. A sealing assembly is provided at one end of the connecting pipe 1, and an adjusting rod 7 is provided on the sealing assembly. One end of the adjusting rod 7 is connected to the valve core 11, and a rotating disk 13 is fixedly installed at the other end of the adjusting rod 7. The initial position of the valve core 11 is between the input end 2 and the second output end 4, at which point water can flow into the connecting pipe 1 through the input end 2. With the valve core 11 blocked, water can be output through the first output end 3. When the flow direction needs to be adjusted, the valve core 11 is pushed towards the first output end 3 by rotating the adjusting rod 7. When the valve core 11 is below the input end 2, the input end 2 can be completely blocked. At this time, no water will flow from the first output end 3 or the second output end 4. When the valve core 11 moves further towards the first output end 3, the water flowing into the input end 2 can flow out through the second output end 4, thereby realizing the switching from the first output end 3 to the second output end 4. Since the width of the valve core 11 is greater than the inner diameter of the input end 2 when the valve core 11 moves below the input end 2, the water flow can be controlled at each output end when the valve core 11 is in different positions, with the flow rate remaining constant.

[0025] As a preferred technical solution in this embodiment, the width of the valve core 11 is greater than the inner diameter of the input end 2. When the valve core 11 is located below the input end 2, it can completely block the input end 2. At this time, neither the first output end 3 nor the second output end 4 will produce water. As the valve core 11 moves from the first output end 3 to the second output end 4, adjusting the position of the valve core 11 below the input end 2 can gradually reduce the water flow at the second output end 4. The closer the valve core 11 is to the second output end 4, the smaller the water flow at the second output end 4 becomes until the water flow stops, and vice versa.

[0026] As a preferred technical solution of this embodiment, the sealing assembly includes a hexagonal connector 5 and a sealing nut 6 fixedly installed on the hexagonal connector 5. The sealing nut 6 is threadedly connected to one end of the connecting pipe 1. The sealing nut 6 can be removed from the connecting pipe 1 by rotating the hexagonal connector 5.

[0027] As a preferred technical solution of this embodiment, the adjusting rod 7 is provided with a second threaded section 10, and the valve core 11 is threadedly connected to the adjusting rod 7 through the second threaded section 10. The adjusting rod 7 is set to rotate clockwise in the screwing direction. By rotating the valve core 11, the valve core 11 can be separated and disassembled from the adjusting rod 7.

[0028] As a preferred technical solution of this embodiment, the adjusting rod 7 is provided with a first threaded section 9, which is threadedly connected to the inner hole of the sealing nut 6 and the hexagonal connector 5, and the adjusting rod 7 is configured to rotate clockwise in the screwing direction; the adjusting rod 7 can be separated and disassembled from the sealing assembly by rotating the adjusting rod 7 counterclockwise.

[0029] As a preferred technical solution in this embodiment, the adjusting rod 7 is provided with a through groove 8, which is located between the first threaded section 9 and the second threaded section 10. The through groove 8 is provided to ensure that while the input end 2 outputs water to the second output end 4, the presence of the adjusting rod 7 reduces the impact on the flow of water.

[0030] As a preferred technical solution in this embodiment, multiple scraping teeth 12 are provided on both circular end faces of the valve core 11. The multiple scraping teeth 12 are arranged in a circular array with the axis of the valve core 11 as the axis. When the valve core 11 rotates with the adjusting rod 7, it will also rotate. The rotation of the valve core 11 enables the multiple scraping teeth 12 to perform circular scraping on the inner wall of the connecting pipe 1, scraping off the scale on the connecting pipe 1 and letting it flow out along the output end, without causing accumulation inside the pipe.

[0031] As a preferred technical solution in this embodiment, a wear-resistant rubber layer 14 is provided at the contact points between the plurality of scraper teeth 12 and the inner wall of the connecting pipe 1; the wear-resistant rubber layer 14 can increase the wear resistance of the scraper teeth 12, and on the other hand, can prevent the scraper teeth 12 from generating noise during the scraping process.

[0032] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
