The flange body 100 is circumferentially arranged outside the inner tube 10, and the fluid in the outer tube 20 can flow in the gap between the flange body 100 and the inner wall of the outer tube 20. A part of the fastening structure 200 is detachably connected to the flange body 100, and another part of the fastening structure 200 is inserted between the inner wall of the flange body 100 and the outer wall of the inner tube 10, and the inner diameter of the fastening structure 200 can be adjusted. In other words, the flange body 100 can be detachably positioned on the outer wall of the inner tube 10 through the fastening structure 200, which simplifies the installation process, avoids the welding process, effectively avoids the safety problems caused by welding, and enhances the replaceability of the support member. And the inner diameter of the fastening structure 200 can be adjusted to adapt to the positioning and installation of the flange body 100 with different inner diameters on the inner tube 10 with different inner diameters, thereby enhancing the applicability of the support member.

[0042] Specifically, the support member further includes a heat insulating structure 300. The heat insulating structure 300 is detachably connected to the side of the flange body 100 away from the fastening structure 200, a part of the heat insulating structure 300 is supported on the inner wall of the outer tube 20, and another part is spaced apart from the inner wall of the outer tube 20. In other words, the heat insulating structure 300 has both a supporting function for the outer tube 20 and a heat insulating function.

[0043] More specifically, the heat insulation structure 300 includes a support portion 310 and an escape portion 320. The support portions 310 are two and are respectively disposed on both sides of the escape portion 320 and protrude from the escape portion 320 so as to abut against the inner wall of the outer tube 20. A gap is left between the escape portion 320 and the inner wall of the outer tube 20, so that the fluid in the outer tube 20 can flow between the escape portion 320 and the inner wall of the outer tube 20.

[0044] More specifically, there are multiple thermal insulation structures 300. Multiple thermal insulation structures 300 are evenly arranged on the flange body 100 along the circumferential direction to achieve uniform support for the outer tube 20. In this embodiment, there are two thermal insulation structures 300, which are arranged opposite to each other and connected to the flange body 100 by bolts.

[0045] Reference Figure 4 and Figure 5 The fastening structure 200 includes a first fastening member 210 and a second fastening member 220. The first fastening member 210 and the second fastening member 220 are arranged opposite to each other and are respectively connected to one side of the flange body 100.

[0046] Specifically, the first fastener 210 includes a first wedge-shaped portion 211 and a first connecting portion 212 that are integrally formed at an angle or fixed to each other. The first connecting portion 212 is connected to the flange body 100, and the first wedge-shaped portion 211 is sandwiched between the flange body 100 and the inner tube 10. In the direction away from the first connecting portion 212, the thickness of the first wedge-shaped portion 211 gradually decreases.

[0047] Similarly, the second fastener 220 includes a second wedge-shaped portion 221 and a second connecting portion 222 that are integrally formed at an angle or fixed to each other; the second connecting portion 222 is connected to the flange body 100, and the second wedge-shaped portion 221 is clamped between the flange body 100 and the inner tube 10, and the thickness of the second wedge-shaped portion 221 gradually decreases in the direction away from the second connecting portion 222.

[0048] Specifically, the first connection portion 212 is connected to the flange body 100 through a first adjusting bolt 213, and the depth of the first wedge-shaped portion 211 inserted between the flange body 100 and the inner tube 10 can be adjusted by the first adjusting bolt 213.

By deepening the threading depth of the first adjusting bolt 213 on the flange body 100 and the threading depth of the second adjusting bolt 223 on the flange body 100, the depth of the first wedge-shaped portion 211 inserted between the flange body 100 and the inner tube 10 can be deepened, and the depth of the second wedge-shaped portion 221 inserted between the flange body 100 and the inner tube 10 can be deepened, thereby reducing the inner diameter of the fastening structure 200 and assisting the flange body 100 to be fastened to the outside of the inner tube 10. Conversely, by operating the first adjusting bolt 213 and the second adjusting bolt 223, the depth of the first wedge-shaped portion 211 inserted between the flange body 100 and the inner tube 10 can be reduced, and the depth of the second wedge-shaped portion 221 inserted between the flange body 100 and the inner tube 10 can be reduced, thereby increasing the inner diameter of the fastening structure 200, making it easier to disassemble or suitable for installation of the flange body 100 on the inner tube 10 with a larger inner diameter.

[0049] More specifically, there are a plurality of first adjusting bolts 213, and the plurality of first adjusting bolts 213 are evenly distributed on the first connecting portion 212. There are a plurality of second adjusting bolts 223, and the plurality of second adjusting bolts 223 are evenly distributed on the second connecting portion 222. Through the above arrangement, the installation reliability of the first fastener 210 and the second fastener 220 on the flange body 100 can be enhanced.

[0050] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention.
