Description

Technical Field

[0001] The utility model relates to the technical field of aluminum alloy flanges, and particularly relates to a stable extrusion type aluminum alloy flange. Background Art

[0002] Aluminum alloy flanges are mainly used for connecting pipelines to ensure the stability and safety of fluid transmission. In many fields such as petrochemical industry, power industry, and food processing, aluminum alloy flanges are indispensable pipeline connection components and have excellent properties such as corrosion resistance, light weight, and good thermal conductivity.

[0003] During the implementation of this solution, the inventor found that the following problems in the prior art have not been well solved: Traditional aluminum alloy flanges are connected together by bolts and nuts in an extrusion manner. However, under the impact of vibration, the connection between the nuts and bolts will become loose. For example, in harsh environments with large temperature changes, high humidity, a lot of dust, or vibration in the working environment, and the impact force (transient flow pressure wave) of the flowing medium in the pipeline, vibration and impact will cancel the friction between the bolts and the connected parts, ultimately causing the bolts to "rotate and loosen" on the threads, and the joint loses the clamping force, resulting in an unstable connection at its joint. Summary of the Utility Model

[0004] The main purpose of the utility model is to provide a stable extrusion type aluminum alloy flange, which can effectively solve the problems in the background art.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] A stable extrusion type aluminum alloy flange includes pipelines. The number of the pipelines is two. Flange plates are fixedly arranged at the closer ends of the pipelines. A plurality of bolts are inserted through between the two flange plates. Nuts are threadedly connected to the outer walls of the ends of the bolts passing through the flange plates. Fixing seats are welded to the outer walls of the flange plates at the nut positions. Adjusting frames are arranged above the nuts at the positions of the fixing seats. Adjusting cavities are drilled at the positions above the nuts of the fixing seats and the adjusting frames. Stable tubes are fixedly arranged in the adjusting cavities of the fixing seats. Pressure columns are inserted through the interiors of the stable tubes. T-shaped clamps are fixedly arranged at the ends of the pressure columns close to the nuts. L-shaped insertion rods are fixedly arranged at the front ends of the T-shaped clamps. Fixing rods are fixedly arranged at the ends of the bolts passing through the nuts. Rod holes are drilled in the fixing rods.

[0007] Preferably, the inner dimensions of the T-shaped clamps respectively match the outer dimensions of the nuts, and the inner walls of the T-shaped clamps respectively contact the outer walls of the nuts.

[0008] Preferably, the inner diameter sizes of the rod holes respectively match the outer diameter sizes of the ends of the L-shaped insertion rods away from the T-shaped clamps, and the ends of the L-shaped insertion rods away from the T-shaped clamps are respectively inserted into the interiors of the rod holes.

[0009] Preferably, the pressure columns are respectively slidably connected after passing through the stabilizing tubes.

[0010] Preferably, ear seats are fixed on the two side walls of the adjusting cavity of the adjusting frame, spring rods are fixed on the tops of the ear seats, and a top plate is arranged above between the two spring rods.

[0011] Preferably, the ends of the pressure columns passing through the stabilizing tubes are respectively fixedly connected to the bottom of the top plate.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] 1. After the two flange plates are connected together by bolts and nuts, the T-shaped clamp covers the outer wall of the nut, the pressure column at the top is restricted by the stabilizing tube bundle, and the fixing seat is welded on the flange plate, so that the nut for connecting the bolt can be restricted, and the effect of thread loosening will not occur under the condition of vibration and impact, ensuring the stability of the connection between the two flange plates.

[0014] 2. The fixing rod fixed to the tail end of the bolt passing through one end of the nut can penetrate through the rod hole and the L-shaped insertion rod on the front side of the T-shaped clamp. The L-shaped insertion rod can achieve the effect of not moving in position due to the stability of the T-shaped clamp. When the L-shaped insertion rod is inserted into the rod hole, it can restrict the fixing rod, so that the bolt also remains in the current position. Therefore, the bolt will not have the effect of thread loosening under the condition of vibration and impact, increasing the stability of the connection between the two flange plates.

[0015] 3. When it is necessary to disassemble the bolts and nuts to separate the flange plates and the pipeline, the T-shaped clamp is pushed towards the end away from the nut, and the pressure column is restricted and moved upward through the combined use of the ear seat, spring rod and top plate. Until the T-shaped clamp is removed from the outer wall of the nut and the L-shaped insertion rod is pulled out of the rod hole, the nut can be rotated for disassembly. The operation is simple and convenient, and does not affect the normal disassembly work. BRIEF DESCRIPTION OF THE DRAWINGS

Specific embodiments

[0021] In order to make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the present utility model will be further elaborated below in conjunction with specific embodiments.

[0022] As Figures 1-4 shown, a stable extrusion - type aluminum alloy flange includes pipelines 1, and the number of pipelines 1 is two. Flange plates 2 are fixed to the adjacent ends of the pipelines 1. A plurality of bolts 12 are inserted through between the two flange plates 2. Nuts 13 are thread - connected to the outer walls of the ends of the bolts 12 passing through the flange plates 2. Fixed seats 3 are welded to the outer walls of the flange plates 2 at the positions of the nuts 13. Adjusting frames 4 are arranged above the nuts 13 at the positions of the fixed seats 3. Adjusting cavities 5 are drilled at the positions of the fixed seats 3 and the adjusting frames 4 above the nuts 13. Stabilizing pipes 10 are fixed in the adjusting cavities 5 of the fixed seats 3. Pressing columns 9 are inserted through the interiors of the stabilizing pipes 10. T - shaped clamps 11 are fixed to the ends of the pressing columns 9 close to the nuts 13. L - shaped insertion rods 16 are fixed to the fronts of the T - shaped clamps 11. Fixed rods 14 are fixed to the ends of the bolts 12 passing through the nuts 13. Rod holes 15 are drilled in the fixed rods 14.

[0023] Specifically, the inner dimensions of the T - shaped clamps 11 respectively match the outer dimensions of the nuts 13, and the inner walls of the T - shaped clamps 11 are respectively in contact with the outer walls of the nuts 13, which can limit the nuts 13.

[0024] Specifically, the inner diameter dimensions of the rod holes 15 respectively match the outer diameter dimensions of the ends of the L - shaped insertion rods 16 far from the T - shaped clamps 11, and the ends of the L - shaped insertion rods 16 far from the T - shaped clamps 11 are respectively inserted into the interiors of the rod holes 15, which can stably limit the fixed rods 14.

[0025] Specifically, the pressing columns 9 are respectively slidably connected after passing through the stabilizing pipes 10, making the descent of the T - shaped clamps 11 vertical.

[0026] Specifically, ear seats 6 are fixed to the two side walls of the adjusting frame 4 located inside the adjusting cavity 5. Spring rods 7 are fixed to the tops of the ear seats 6. Above the two spring rods 7, a top plate 8 is arranged. One ends of the pressing columns 9 passing through the stabilizing tubes 10 are respectively fixedly connected to the bottom of the top plate 8, so that the pressing columns 9 can be limited to rise when the nuts 13 and bolts 12 are disassembled.

[0027] Working principle: After the bolt 12 and the nut 13 connect the two flange plates 2 together, the T-shaped clamp 11 covers the outer wall of the nut 13. The pressing column 9 at its top is restricted by the stabilizing tube 10, and the fixing seat 3 is welded to the flange plate 2. Thus, the nut 13 for connecting the bolt 12 can be restricted. In the case of vibration and impact, there will be no effect of the thread backing out, ensuring the stability of the connection between the two flange plates 2. The fixing rod 14 fixed to the tail end of the bolt 12 passing through the nut 13 can penetrate through the rod hole 15 and the L-shaped insertion rod 16 on the front side of the T-shaped clamp 11. The L-shaped insertion rod 16 can achieve the effect of staying in place due to the stability of the T-shaped clamp 11. When the L-shaped insertion rod 16 is inserted into the rod hole 15, it can restrict the fixing rod 14, so that the bolt 12 also stays in its current position. Thus, the bolt 12 will not have the effect of the thread backing out under vibration and impact, increasing the stability of the connection between the two flange plates 2. When it is necessary to disassemble the bolt 12 and the nut 13 to separate the flange plate 2 and the pipeline 1, the T-shaped clamp 11 is pushed towards the end away from the nut 13. The pressing column 9 is restricted to move upward through the combined use of the ear seat 6, the spring rod 7, and the top plate 8. Until the T-shaped clamp 11 is removed from the outer wall of the nut 13 and the L-shaped insertion rod 16 is pulled out of the rod hole 15, the nut 13 can be rotated for disassembly. The operation is simple and convenient, without affecting the normal disassembly work.
