Description

Technical Field

[0001] This application belongs to the field of pipeline technology, specifically relating to an externally connected pipeline for a device cover plate. Background Technology

[0002] Pipe connection refers to linking two or more pipe sections together to form a complete piping system. When selecting a pipe connection method, factors such as pipe material, pipe size, operating conditions, safety, and maintenance requirements need to be considered. It is crucial to choose a suitable connection method and ensure the quality and reliability of the connection.

[0003] Traditional pipe covers, such as Figure 1 As shown, the flange plate on the outside of the pipe opening cover is bolted to a second flange to increase the stability of the connection. However, the threads of the flange plate are susceptible to corrosion, which can cause problems in the connection with the second flange. In such cases, the entire flange plate needs to be replaced, which is not conducive to future maintenance and replacement. Utility Model Content

[0004] This application provides a device cover plate for connecting to an external pipe to solve the above-mentioned technical problems.

[0005] To solve the above-mentioned technical problems, the present application adopts the following technical solution: a device cover plate for connecting external pipelines, including a flange plate, a connecting cylinder, and a movable flange; the end cap of the connecting cylinder has a discharge port at its center and a feed port at its side end; the flange plate is fixedly connected to the end cap and the central hole of the flange plate is sleeved on the outside of the discharge port; a movable flange sleeved on the outside of the discharge port is movably disposed in the central hole; the discharge port is connected to a second flange; wherein, the through hole on the outer side of the center of the second flange is connected to the movable flange by a first bolt.

[0006] Furthermore, an annular groove is provided on the side end of the central hole near the connecting cylinder, and the movable flange is disposed in the annular groove.

[0007] Furthermore, the outer diameter of the movable flange is larger than the inner diameter of the central hole and smaller than the inner diameter of the annular groove; the inner diameter of the movable flange is larger than the outer diameter of the discharge port.

[0008] Furthermore, the flange connection hole of the movable flange is projected onto the end cover in the orthographic projection of the center hole onto the end cover.

[0009] Furthermore, a first connection hole is provided on the outer side of the flange plate.

[0010] Furthermore, the outer side of the second flange is provided with a second connecting hole corresponding to the first connecting hole, and the second connecting hole is connected to the first connecting hole by a second bolt.

[0011] The beneficial effects of this application are as follows: By incorporating a movable flange plate within a conventional flange plate, the installation angle can be flexibly adjusted when connecting the second flange to the movable flange, facilitating the overall connection and installation. Furthermore, if the connection hole of the movable flange is damaged by corrosion, only the movable flange needs to be replaced, without replacing the entire flange plate, thus simplifying future maintenance.

[0015] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0016] like Figure 1-3 As shown, this application provides an external connection pipeline for an equipment cover plate, including a flange plate 1, a connecting cylinder 2, and a movable flange 3; the end cap 21 of the connecting cylinder 2 has a discharge port 22 at its center, and a feed port 23 at its side end; the flange plate 1 is fixedly connected to the end cap 21, and the central hole 11 of the flange plate 1 is sleeved on the outside of the discharge port 22; the movable flange 3, sleeved on the outside of the discharge port 22, is movably disposed in the central hole 11; the discharge port 22 is connected to a second flange 4; wherein, the through hole 41 on the outer side of the center of the second flange 4 is connected to the movable flange 3 by a first bolt 5. In the above design, the flange plate 1 is fixedly connected to the end cap 21 of the connecting cylinder 2 by welding or threaded connection. By setting the movable flange 3 at the center of the flange plate 1, the second flange 4 can be connected to the movable flange 3, thereby connecting the second flange 4 to the flange plate 1. When the movable flange 3 is damaged, only the movable flange 3 needs to be replaced in time, without replacing the entire flange plate 1, thus reducing maintenance costs.

[0017] An annular groove 12 is provided on the side end of the central hole 11 near the connecting cylinder 2, and the movable flange 3 is disposed in the annular groove 12. The annular groove 12 in the above design is used to house the movable flange 3.

[0018] The outer diameter of the movable flange 3 is larger than the inner diameter of the central hole 11 and smaller than the inner diameter of the annular groove 12; the inner diameter of the movable flange 3 is larger than the outer diameter of the discharge port 22. The above design prevents the movable flange 3 from falling out of the central hole 11, while providing a certain amount of room for movement to facilitate adjustment of the connection angle, thereby connecting it in parallel with the through hole 41 of the second flange 4, thus fixing the position of the second flange 4.

[0019] The flange connection hole 31 of the movable flange 3 is projected onto the end cover 21 in the projection of the central hole 11 onto the end cover 21. In the above design, the first bolt 5 can pass through the central hole 11 and connect to the flange connection hole 31 of the movable flange 3. At the same time, tightening the first bolt 5 allows the second flange 4 to be indirectly connected to the flange plate 1 through the movable flange 3.

[0020] The outer side of the flange plate 1 is provided with a first connection hole 13, which can be connected to the outer side of the second flange 4.

[0021] The outer side of the second flange 4 is provided with a second connecting hole 42 corresponding to the first connecting hole 13. The second connecting hole 42 and the first connecting hole 13 are connected by a second bolt 6. The above design allows for a primary connection between the through hole 41 in the middle of the second flange 4 and the movable flange 3. Then, by passing the second bolt 6 through the first connecting hole and the second connecting hole 42, the outer plate of the second flange 4 can be connected to the flange plate 1, further stabilizing the overall connection of the flange.

[0022] The specific working principle is as follows: the interface in the second flange 4 is connected to the outlet 22 of the connecting cylinder 2. The first bolt 5 is passed through the through hole 41 of the second flange 4 and connected to the flange connection hole of the movable flange 3. Simultaneously, the first bolt 5 is tightened, causing the movable flange 3 to press against the bottom of the annular groove 12, thus indirectly connecting the flange plate 1 and the second flange 4. Then, the second flange 4 is further connected to the flange plate 1 using the second bolt 6. When the threads of the movable flange 3 are corroded and damaged, the first bolt 5 and the second bolt 6 are loosened, the second flange 4 is removed, and the flange plate 1 can be separated from the end cover 21 of the connecting cylinder 2 to replace the movable flange 3. The second flange 4 is then reconnected using the same method.

[0023] The above description is merely an embodiment of this application and does not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
