[0019] In addition, although the terms “first”, “second”, etc. are used herein to describe different elements, such terms are merely used to distinguish elements or operations described with the same technical terms.

[0020] See also Figure 1 , which is a stereoscopic diagram of a fixture device for purging a thin-walled stainless steel clean pipeline according to an embodiment of the present application; as shown in the figure, the fixture device 1 for purging a thin-walled stainless steel clean pipeline according to the present embodiment is suitable for a thin-walled stainless steel clean pipeline welding test. The fixture device 1 for purging a thin-walled stainless steel clean pipeline comprises a first plugging plate 2, a second plugging plate 3, a support bracket 4 and a first driving member 5. The first plugging plate 2 is arranged vertically. One side of the first plugging plate 2 has a first plugging surface 21. The second plugging plate 3 is arranged opposite to the first plugging plate 2. The second plugging plate 3 is located on the left side of the first plugging plate 2. The second plugging plate 3 has a second plugging surface 31 on one side adjacent to the first plugging plate 2. The second plugging surface 31 is opposite to the first plugging surface 21. The support bracket 4 is arranged between the first plugging plate 2 and the second plugging plate 3. The support bracket 4 has an arc-shaped support surface 41. The first driving member 5 is connected to the second plugging plate 3. The first driving member 5 pushes the second plugging plate 3 to move relatively close to and away from the first plugging plate 2. The first driving member 5 uses a hydraulic pump.

[0021] When the clamp device 1 for purging the thin-walled stainless steel clean pipe of this embodiment is used, the thin-walled stainless steel clean pipe is placed on the arc-shaped supporting surface 41 of the supporting bracket 4, and the thin-walled stainless steel clean pipe is supported by the supporting bracket 4. Then the first driving member 5 pushes the second blocking plate 3 relatively close to the first blocking plate 2 until the second blocking plate 3 and the first blocking plate 2 are clamped on both sides of the thin-walled stainless steel clean pipe. At this time, the second blocking surface 31 of the second blocking plate 3 and the first blocking surface 21 of the first blocking plate 2 are respectively blocked on both sides of the thin-walled stainless steel clean pipe, so as to achieve the sealing of the pipe mouth of the thin-walled stainless steel clean pipe. The clamp device 1 for purging the thin-walled stainless steel clean pipe of this embodiment can improve the sealing of the thin-walled stainless steel clean pipe by clamping the second blocking plate 3 and the first blocking plate 2 on both sides of the thin-walled stainless steel clean pipe, thereby avoiding the occurrence of pressure relief.

[0022] Furthermore, the clamp device 1 for purging thin-walled stainless steel clean pipes further includes a polyethylene gasket (not shown in the figure), which is arranged between the second sealing surface 31 and one side of the thin-walled stainless steel clean pipe and between the first sealing surface 21 and the other side of the thin-walled stainless steel clean pipe, thereby further improving the sealing performance of the thin-walled stainless steel clean pipe.

[0023] In this embodiment, the first blocking surface 21 and the second blocking surface 31 are stainless steel clean plates. The main bodies of the first blocking plate 2 and the second blocking plate 3 use carbon steel plates. The first blocking plate 2 and the second blocking plate 3 have the same structure. The first blocking plate 2, the first blocking surface 21, the second blocking plate 3 and the second blocking surface 31 are all circular plates. The stainless steel clean plate and the carbon steel plate are fixed together by screws.

[0024] In this embodiment, the clamp device 1 for purging thin-walled stainless steel clean pipes also includes a supporting frame 6. The supporting frame 6 is a rectangular frame formed by welding angle steels and channel steels. The first sealing plate 2 is arranged in the supporting frame 6 and is located on one side of the supporting frame 6. The first driving member 5 is arranged on the other side of the supporting frame 6. The supporting bracket 4 is arranged in the supporting frame 6. There are two supporting brackets 4, and the two supporting brackets 4 are arranged between the first sealing plate 2 and the second sealing plate 3 at intervals and in parallel. By placing the first sealing plate 2, the second sealing plate 3 and the supporting bracket 4 in the supporting frame 6, when the thin-walled stainless steel clean pipe is placed on the supporting bracket 4 and moved, it is only necessary to move the supporting frame 6, which can reduce the wear during the movement of the pipe section.

[0025] In this embodiment, the fixture device 1 for purging a thin-walled stainless steel clean pipe further includes a second driving member (not shown in the figure). The second driving member is connected to the first blocking plate 2. The second driving member pushes the first blocking plate 2 to move relatively closer to and away from the second blocking plate 3. The position of the thin-walled stainless steel clean pipe on the support bracket 4 is adjusted by the second driving member pushing the first blocking plate 2 and the first driving member 5 pushing the second blocking plate 3.

[0026] To summarize, the present application provides a clamp device for purging thin-walled stainless steel clean pipes, in which the thin-walled stainless steel clean pipes are supported by a support frame, and the second sealing plate is pushed relatively close to the first sealing plate by a first driving member. The second sealing plate and the first sealing plate are clamped on both sides of the thin-walled stainless steel clean pipe, and the second sealing surface of the second sealing plate and the first sealing surface of the first sealing plate are respectively sealed on both sides of the pipe openings of the thin-walled stainless steel clean pipe, thereby achieving the sealing of the pipe openings of the thin-walled stainless steel clean pipe, improving the sealing performance of the thin-walled stainless steel clean pipe, and avoiding the occurrence of pressure relief.
