Therefore, they are widely used in various pipeline systems that need to withstand high pressure and temperature. However, under high pressure and temperature conditions, the butt-welding flanges are easily oxidized after long-term use, resulting in corrosion. When corrosion occurs, the existing technology is inconvenient to maintain the corrosion. In severe cases, the butt-welding flanges need to be replaced, which is inconvenient to operate and costly. In view of the shortcomings of the existing technology, the utility model provides a corrosion-resistant butt-welding flange to solve the above problems. Utility Model Content

[0020] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0021] The embodiments of the present application provide corrosion-resistant butt-weld flanges, thereby solving the problem that under high pressure and temperature conditions, the butt-weld flanges are easily oxidized after long-term use, thereby causing corrosion. When corrosion occurs, the existing technology is relatively inconvenient to maintain the corrosion. In severe cases, the butt-weld flanges need to be replaced, which is inconvenient to operate and costly.

[0022] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0023] The utility model embodiment discloses a corrosion-resistant butt welding flange, according to the attached Figure 1-4 As shown, it includes a flange body 1, a clamping base 2 is provided on the flange body 1, a zinc block 3 is embedded and clamped inside the clamping base 2, and a clamping sealing unit 4 for limiting the position of the zinc block 3 is provided on the clamping base 2. The design of the clamping base 2 and the clamping sealing unit 4 makes it easy to clamp the zinc block 3 inside the flange body 1;

[0024] When the zinc block 3 is embedded in the clamping base 2, it mainly plays the role of sacrificial anode protection. When the flange body 1 is exposed to a corrosive environment, the zinc block 3 will corrode first, thereby protecting the flange body 1 from corrosion.

[0025] The clamping and sealing unit 4 is used to limit and seal the zinc block 3, ensuring that the zinc block 3 can be firmly fixed inside the clamping base 2 and preventing corrosive substances from entering.

[0026] The clamping and sealing unit 4 includes a guide rail frame 41 provided on the clamping base 2 and a clamping platform 42 movably clamped on the guide rail frame 41 . The clamping platform 42 is provided with a sealing block 43 movably clamped inside the clamping base 2 .

[0027] The guide rail frame 41 is a part of the clamping sealing unit 4, which provides a sliding track so that the clamping platform 42 can move on it. This helps to adjust the position of the clamping platform 42 so that the zinc block 3 is better fixed.

[0028] The clamping platform 42 is a part that is slidably connected to the guide rail frame 41 and is used to carry and fix the sealing block 43. By adjusting the position of the clamping platform 42, the zinc block 3 can be tightly fixed.

[0029] The sealing block 43 is arranged on the clamping platform 42 , and its main function is to provide a sealing effect to prevent corrosive substances from entering the interior of the clamping base 2 , while fixing the zinc block 3 .

[0030] A screw rod 44 is threadedly connected to the guide rail frame 41 and is rotatably connected to the clamping platform 42. Screw rod 44 is threaded onto the guide rail frame 41, and rotating screw rod 41 drives the clamping platform 42 on the guide rail frame 41. This provides a simple and effective way to adjust the position of the clamping platform 42. A rotating handle 441 is provided on screw rod 44, which makes rotation of screw rod 44 effortless and convenient.

[0031] An adjustment platform 45 is slidably connected to the clamping platform 42. The adjustment platform 45 is rotatably connected to the screw 44. An elastic member 46 is provided between the adjustment platform 45 and the clamping platform 42. The device includes the adjustment platform 45 and the elastic member 46. The elastic member 46 is disposed between the adjustment platform 45 and the clamping platform 52, and the elastic member 46 provides a buffering and elastic support effect. This helps ensure that the clamping platform 42 can maintain appropriate pressure when securing the zinc block 3, and the zinc block 3 fits well within the clamping base 2, thereby improving the corrosion protection of the flange body 1 and preventing damage to the zinc block 3 caused by overtightening.

[0032] The elastic member 46 is a stainless steel arc-shaped spring piece. The material of the stainless steel arc-shaped spring piece has good corrosion resistance and elasticity, good stability, and long service life, and meets the use requirements of buffering and elastic support.

[0033] The clamping platform 42 is provided with a support column 421, which passes through the adjustment platform 45 and is fixedly connected to a stopper 422. The support column 421 is mounted on the clamping platform 42, passes through the adjustment platform 45, and is fixedly connected to the stopper 422. The support column 421 and the stopper 422 provide additional support, helping to maintain the stability and positional accuracy of the clamping platform 42. The stopper 422 is used to limit the range of movement of the clamping platform 42, preventing it from sliding excessively.

[0034] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and improvements are intended to fall within the scope of the present invention.
