Description

Technical Field

[0001] This utility model relates to the field of tobacco production equipment technology, and in particular to a pipeline connection valve. Background Technology

[0002] Tobacco processing requires a cleaning process. The tobacco cleaning equipment has multiple branch pipelines. The existing valves control the opening and closing of the pipelines via handles or adjusting rods. However, the existing branch pipelines are arranged in a compact manner, so it is not possible to install valves on every pipeline. Only a main valve can be installed on the main pipeline. By controlling the opening and closing of the main pipeline, multiple branch pipelines can be opened or closed simultaneously. As a result, the cleaning equipment cannot be used to clean a specific part of the tobacco, which results in poor flexibility and a large waste of resources.

[0003] Therefore, there is an urgent need for a pipeline connection valve to solve the above-mentioned technical problems. Utility Model Content

[0004] The purpose of this utility model is to provide a pipeline connection valve that occupies little space and can solve the problem that existing multiple branch pipelines cannot have valves installed on each branch pipeline due to their compact layout. Instead, the main valve is used to control the opening and closing of the main pipeline, and thus the opening and closing of multiple branch pipelines are controlled simultaneously, resulting in poor flexibility of cleaning equipment and a large consumption of resources.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] A pipeline connection valve is configured to connect a first pipeline and a second pipeline, wherein the outlet of the first pipeline is opposite to the inlet of the second pipeline. The pipeline connection valve includes a fixed baffle, an opening and closing baffle, a locking element, and two fastening rings. The fixed baffle blocks the outlet of the first pipeline and has a first eccentric hole. The two fastening rings are respectively sleeved on the outer periphery of the outlet of the first pipeline and the outer periphery of the inlet of the second pipeline. The opening and closing baffle is fitted with the fixed baffle and clamped between the two fastening rings. The opening and closing baffle has a second eccentric hole. The locking element is used to lock the two fastening rings and the opening and closing baffle.

[0007] As a preferred technical solution for pipeline connection valves, the outer peripheral surface of the opening and closing baffle is provided with knurling.

[0008] As a preferred technical solution for pipeline connection valves, the outer circumferential surface of the locking ring is knurled.

[0009] As a preferred technical solution for the pipeline connection valve, the pipeline connection valve further includes two retaining rings, which are respectively sleeved on the outer periphery of the first pipeline outlet and the outer periphery of the second pipeline inlet; the fastening ring includes a retaining ring, and when the two fastening rings are respectively sleeved on the outer periphery of the first pipeline outlet and the outer periphery of the second pipeline inlet, the retaining ring is in contact with the retaining ring, and the openings of the two fastening rings are opposite to the retaining ring.

[0010] As a preferred technical solution for pipeline connection valves, the retaining ring is threadedly connected to the outer periphery of both the first pipeline outlet and the second pipeline inlet.

[0011] As a preferred technical solution for the pipeline connection valve, the pipeline connection valve further includes two sealing gaskets, which are respectively fixed to the two end faces of the opening and closing baffle. The sealing gaskets are provided with clearance holes, which correspond to the second eccentric hole.

[0012] As a preferred technical solution for pipeline connection valves, the sealing gasket is a hard rubber gasket.

[0013] As a preferred technical solution for pipeline connection valves, the locking element includes a bolt and a nut, wherein the bolt passes through the snap ring and the opening / closing baffle and is threadedly connected to the nut.

[0014] As a preferred technical solution for pipeline connection valve, the fastening ring is provided with a mounting hole, the opening and closing baffle is provided with an assembly hole corresponding to the mounting hole, and the bolt passes through the mounting hole and the assembly hole and is threadedly connected to the nut.

[0015] As a preferred technical solution for pipeline connection valves, the thickness of the opening and closing baffle is 5mm-8mm.

[0016] The beneficial effects of this utility model are as follows:

[0017] The pipeline connection valve provided in this embodiment seals the outlet of the first pipeline with a fixed baffle, and two locking rings are respectively fitted around the outer periphery of the first pipeline outlet and the outer periphery of the second pipeline inlet. The opening and closing baffle is attached to the fixed baffle and clamped between the two locking rings. At the same time, the two locking rings and the opening and closing baffle are locked with a locking device. When it is necessary to control the opening and closing of the branch pipeline, the operator only needs to rotate the locking ring to make the opening and closing baffle rotate. The second eccentric hole on the opening and closing baffle will coincide with or offset the first eccentric hole in the fixed baffle, so that the first pipeline and the second pipeline are connected or disconnected, thereby realizing the control of the opening and closing of the branch pipeline. Compared to existing valves, this valve allows for control of branch pipe flow without the need for handles or adjusting rods. It also occupies less space, enabling the installation of a valve on each branch pipe even in compact layouts, allowing for individual control of each branch's flow. This solves the problem of existing cleaning equipment only being able to control the main pipe's flow through the main valve, thus limiting the simultaneous control of multiple branch pipes. This makes the cleaning equipment more flexible to use and effectively reduces resource waste. Attached Figure Description

[0026] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0027] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; 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; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0028] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0029] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, 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 utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0030] like Figures 1 to 4As shown, this embodiment provides a pipeline connection valve configured to connect a first pipeline 100 and a second pipeline 200 to form a branch pipeline that is easy to control for opening and closing. The outlet of the first pipeline 100 is opposite to the inlet of the second pipeline 200. The pipeline connection valve includes a fixed baffle 1, an opening and closing baffle 2, a locking member 3, and two fastening rings 4. The fixed baffle 1 blocks the outlet of the first pipeline 100 and has a first eccentric hole 11. The two fastening rings 4 are respectively fitted around the outer periphery of the outlet of the first pipeline 100 and the outer periphery of the inlet of the second pipeline 200. The opening and closing baffle 2 fits against the fixed baffle 1 and is clamped between the two fastening rings 4. The opening and closing baffle 2 has a second eccentric hole 21. The locking member 3 is used to lock the two fastening rings 4 and the opening and closing baffle 2. When the locking ring 4 is rotated by external force, the opening and closing baffle 2 will rotate. During the rotation of the opening and closing baffle 2, the second eccentric hole 21 will coincide with or be offset from the first eccentric hole 11. When the first eccentric hole 11 coincides with the second eccentric hole 21, the first pipeline 100 and the second pipeline 200 are connected, that is, the branch pipeline is connected. When the first eccentric hole 11 and the second eccentric hole 21 are offset, the first pipeline 100 and the second pipeline 200 are disconnected, that is, the branch pipeline is closed.

[0031] The pipeline connection valve provided in this embodiment seals the outlet of the first pipeline 100 with a fixed baffle 1, and places two locking rings 4 on the outer periphery of the outlet of the first pipeline 100 and the outer periphery of the inlet of the second pipeline 200 respectively. The opening and closing baffle 2 is attached to the fixed baffle 1 and clamped between the two locking rings 4. At the same time, the locking member 3 locks the two locking rings 4 and the opening and closing baffle 2. When it is necessary to control the opening and closing of the branch pipeline, the operator only needs to rotate the locking ring 4 to make the opening and closing baffle 2 rotate. The second eccentric hole 21 on the opening and closing baffle 2 will coincide with or offset the first eccentric hole 11 in the fixed baffle 1, so that the first pipeline 100 and the second pipeline 200 are connected or disconnected, thereby realizing the control of the opening and closing of the branch pipeline. Compared to existing valves, this valve allows for control of branch pipe flow without the need for handles or adjusting rods. It also occupies less space, enabling the installation of a valve on each branch pipe even in compact layouts, allowing for individual control of each branch's flow. This solves the problem of existing cleaning equipment only being able to control the main pipe's flow through the main valve, thus limiting the simultaneous control of multiple branch pipes. This makes the cleaning equipment more flexible to use and effectively reduces resource waste.

[0032] Preferably, the outer circumferential surface of the opening / closing baffle 2 is knurled to facilitate the operator's rotation of the baffle 2, thereby more conveniently controlling the opening and closing of the branch pipeline. And / or, the outer circumferential surface of the locking ring 4 is knurled to facilitate the operator's rotation of the locking ring 4, causing the opening / closing baffle 2 to rotate, thus controlling the opening and closing of the branch pipeline. Knurling can be applied to the outer circumferential surface of the opening / closing baffle 2 or the outer circumferential surface of the locking ring 4, or simultaneously to both; no specific limitation is made here.

[0033] In this embodiment, as Figures 3 to 5 As shown, the pipeline connection valve also includes two retaining rings 5, which are respectively fitted around the outer periphery of the outlet of the first pipeline 100 and the outer periphery of the inlet of the second pipeline 200. The locking ring 4 also includes a retaining ring 41. When the two locking rings 4 are respectively fitted around the outer periphery of the outlet of the first pipeline 100 and the outer periphery of the inlet of the second pipeline 200, the retaining ring 41 is in contact with the retaining ring 5. The retaining ring 5 limits the locking ring 4, preventing misalignment of the locking ring 4 when the operator rotates it, which could cause gaps between the first pipeline 100 and the second pipeline 200, leading to the outflow of cleaning water and improving the safety of the branch pipeline connection process. For example, the retaining ring 5 is threaded to both the outer periphery of the outlet of the first pipeline 100 and the outer periphery of the inlet of the second pipeline 200, allowing the operator to quickly disassemble the retaining ring 5 and replace it periodically, ensuring the safe use of the pipeline connection valve. During specific assembly, the two locking rings 4 are not configured with the openings of the retaining ring 41 facing each other. Specifically, external threads are provided on the outer periphery of the outlet of the first pipeline 100 and the outer periphery of the inlet of the second pipeline 200, and internal threads are provided on the retaining ring 5. Through the mutual screwing of the external threads and the internal threads, the retaining ring 5 is threadedly connected to the outer periphery of the outlet of the first pipeline 100 and the outer periphery of the inlet of the second pipeline 200.

[0034] Furthermore, the pipeline connection valve also includes two sealing gaskets 6, which are fixed to the two end faces of the opening and closing baffle 2 respectively. Each sealing gasket 6 has a clearance hole, which corresponds to the second eccentric hole 21. The sealing gaskets 6 further improve the sealing performance of the connection between the first pipeline 100 and the second pipeline 200, reducing the risk of leakage between them. In this embodiment, the sealing gasket 6 is made of hard rubber. When the operator rotates the locking ring 4 to control the connection or disconnection of the first pipeline 100 and the second pipeline 200, friction occurs between the fixed baffle 1 and the sealing gasket 6. Since hard rubber has good wear resistance, this further improves the service life of the sealing gasket 6, avoiding frequent replacements and reducing the workload of the operator.

[0035] For example, the locking component 3 includes a nut 32 for a bolt 31. The bolt 31 passes through the retaining ring 4 and the opening / closing stop 2 and is threadedly connected to the nut 32, thereby locking the retaining ring 4 and the opening / closing stop 2 together. Specifically, the retaining ring 4 has a mounting hole, and the opening / closing stop 2 has an assembly hole corresponding to the mounting hole. The bolt 31 passes through the mounting hole and the assembly hole and is threadedly connected to the nut 32. The mounting hole is located on the side of the retaining ring 4 and avoids the stop ring 5, preventing interference between the bolt 31 and the stop ring 5, which would affect the operator's rotation of the retaining ring 4 and make the design of the pipeline connection valve more reasonable.

[0036] In this embodiment, the thickness of the opening / closing baffle 2 is 5mm-8mm to ensure its rigidity, thereby ensuring the service life of the pipeline switching valve. The thickness of the opening / closing baffle 2 needs to be selected according to the specifications of the branch pipeline, and no specific limitations are made here.

[0037] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
