[0035] The present application is further described in detail below with reference to the accompanying drawings.
[0036] The embodiment of the present application discloses a stainless steel pipe sealing mechanism, which is used to ensure the sealing of the connection between adjacent stainless steel pipes, thereby preventing fluid leakage.
[0037] Reference Figure 1 and Figure 2 A stainless steel pipe sealing mechanism includes a sealing sleeve 1 for fitting around the joints of adjacent stainless steel pipes, with an annular groove 11 being provided on the inner wall of the sealing sleeve 1; the sealing sleeve 1 is also provided with a filling assembly 2, which is used for a user to fill sealing filler into the annular groove 11 to seal the joints of adjacent stainless steel pipes.
[0038] Reference Figure 2 and Figure 3 In this embodiment, to facilitate the installation of sealing filler, two filling assemblies 2 are provided. These two filling assemblies 2 are arranged opposite each other. The structure of the taller filling assembly 2 is used as an example: The filling assembly 2 includes a feed hole 12 formed on the outer wall of the sealing sleeve 1. The feed hole 12 is vertically arranged and communicates with the annular groove 11. The sealing sleeve 1 is also connected to a feed pipe 21, which is located within the feed hole 12. The feed pipe 21 is detachably provided with a closure cap 22. Specifically, the feed pipe 21 and the closure cap 22 are threadedly connected. Furthermore, to prevent the feed pipe 21 from rotating excessively and separating from the sealing sleeve 1, a mounting ring 23 is provided on the outer wall of the feed pipe 21, and a stopper 24 is provided on the outer wall of the sealing sleeve 1. The stopper 24 can limit the mounting ring 23, thereby preventing the feed pipe 21 from moving upward and separating from the sealing sleeve 1.
[0039] The usage of this application is as follows: first, put this application on the connection between adjacent stainless steel pipes, and ensure that the annular groove 11 is adjacent to the docking position, then rotate and open the closing cover 22, and inject sealing filler into the feed pipe 21. The material of the sealing filler can be graphite or ceramic. After the annular groove 11 is filled, reinstall the closing cover 22.
[0040] Reference Figure 3 In order to ensure the sealing performance of the sealing filler at the connection between adjacent stainless steel pipes, the feed pipe 21 and the sealing sleeve 1 are threadedly connected. After the annular groove 11 is filled, the sealing filler can be initially compacted by rotating the feed pipe 21 so that the feed pipe 21 moves downward.
[0041] Reference Figure 2 To ensure that the sealing filler can be further compacted, the annular groove 11 includes a first end 111 and a second end 112. In this embodiment, both the first end 111 and the second end 112 are provided with a pushing mechanism 3, which can push the sealing filler in the annular groove 11 to tighten the sealing filler. In other embodiments, the pushing mechanism 3 may be installed only at the first end 111 or only at the second end 112.
[0042] Reference Figure 4 , take the pushing mechanism 3 on the left as an example: the pushing mechanism 3 includes a horizontally arranged sliding member 31, a first end 111 of which is provided with a sliding groove 32, the sliding member 31 is arranged in the sliding groove 32 and the sliding member 31 and the sliding groove 32 are slidingly connected, and the sliding member 31 is provided with a push ring 33 at one end close to the annular groove 11, the push ring 33 is located in the annular groove 11 and the outer wall of the push ring 33 fits the inner wall of the annular groove 11, the aperture of the push ring 33 is the same as the aperture of the sealing sleeve 1, and a pushing assembly 34 is provided at the left end of the sliding member 31, the pushing assembly 34 can drive the sliding member 31 to slide to the right, thereby driving the push ring 33 to move to the right to compact the sealing filler in the annular groove 11.
[0043] Reference Figure 4 The push assembly 34 includes a rotating ring 341. A mounting groove 13 is defined at the left end of the sealing sleeve 1. The rotating ring 341 is threadedly connected to the mounting groove 13. A bearing 342 is located within the mounting groove 13, between the rotating ring 341 and the sliding member 31. The bearing 342 may be a tapered roller bearing or a thrust bearing. The left end of the bearing 342 is connected to the rotating ring 341, and the right end is connected to the sliding member 31. The rotating ring 341 can rotate to move the sliding member 31 to the right. Furthermore, to facilitate the rotation of the rotating ring 341, two mounting posts 343 are provided on the end of the rotating ring 341 away from the groove 11.
[0044] After the annular groove 11 is filled, the rotating ring 341 is driven to rotate by grasping the mounting post 343. At this time, the rotating ring 341 will move to the right, thereby driving the sliding member 31 to move to the right through the bearing 342 and then driving the push ring 33 to move to the right. The push ring 33 will further compact the sealing filler in the annular groove 11.
[0045] Reference Figure 4 In order to prevent the rotating ring 341 from rotating too far and detaching from the sealing sleeve 1, a limiting ring 4 is further provided on the sealing sleeve 1 on the left side of the rotating ring 341. The aperture of the limiting ring 4 is smaller than the outer diameter of the rotating ring 341. The limiting ring 4 can limit the rotating ring 341 and prevent the rotating ring 341 from moving left and detaching from the sealing sleeve 1.
[0046] In addition, for adjacent stainless steel pipes connected horizontally, the present application is relatively stable after installation. However, for adjacent stainless steel pipes connected vertically, the present application may move after long-term use. In order to prevent the above situation from happening, before installing adjacent stainless steel pipes connected vertically, refer to Figure 5 , it is necessary to open a groove on the outer wall of the connection position of adjacent stainless steel pipes. The axial cross-section shape of the groove can be any shape, such as a triangle, trapezoid or rectangle. Then, at this time, the sealing filler will also enter the groove during filling. After the sealing filler is compacted, this application will be difficult to fall off.
[0047] The implementation principle of a stainless steel pipe sealing mechanism in an embodiment of the present application is: first, the present application is placed on the connection between adjacent stainless steel pipes, and the annular groove 11 is ensured to be adjacent to the docking position, and then the closing cover 22 is rotated to open and the sealing filler is injected into the feed pipe 21. After the annular groove 11 is filled, the closing cover 22 is reinstalled; then the mounting column 343 is grasped to drive the rotating ring 341 to rotate, and the rotating ring 341 moves, thereby driving the sliding member 31 to move toward the annular groove 11 through the bearing 342, and then driving the push ring 33 to move toward the annular groove 11. The push ring 33 will further compact the sealing filler in the annular groove 11.
[0048] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
