Description

A pipe connection forged flange Technical Field

[0001] The embodiments disclosed herein relate to the technical field of flanges, and more specifically, to a pipe connection forged flange. Background Technology

[0002] In modern industrial production, flanges, as a key connecting component, are widely used in various fields. Flanges, also known as flange plates or flanges, are mainly used for connections between shafts, pipe ends, and equipment inlets and outlets, ensuring the stable transmission of media in various systems. Among numerous connection methods, flange connections have become an important choice for industrial pipelines and equipment connections due to their advantages such as detachability and sealing performance. Bolts and studs are commonly used elements for flange connections; the preload generated by tightening the bolts or nuts ensures a tight connection between the flanges.

[0003] However, traditional flange connections have many drawbacks. First, traditional flanges are mostly directly connected and fixed with bolts. In actual working conditions, pipelines or equipment are subjected to various complex external forces, such as internal medium pressure fluctuations, external environmental vibrations and impacts, and stresses generated by thermal expansion and contraction. When these external forces cause the flanges to bend, deformation can easily occur between the two flanges. This deformation not only damages the structural integrity of the flanges themselves and reduces their structural strength, but also seriously affects the sealing performance of the entire system. In systems transporting flammable, explosive, toxic, or hazardous media, loss of sealing performance can lead to serious safety accidents, threatening personnel lives, causing environmental pollution, and resulting in huge economic losses.

[0004] Secondly, due to the shortcomings of traditional flanges in terms of structural strength and sealing performance, their service life is relatively short. Frequent maintenance and replacement of flanges not only increase the company's production costs but also lead to prolonged equipment downtime, affecting production efficiency and restricting the company's economic benefits.

[0005] With the continuous advancement of industrial technology and the sustained expansion of production scale, higher requirements are being placed on the reliability, stability, and durability of flange connections. Developing a forged flange for pipe connections with high structural strength, excellent sealing performance, and long service life is urgently needed. This is of significant practical importance for ensuring the safe and efficient operation of industrial production and enhancing enterprise competitiveness. Summary of the Invention

[0006] To overcome the above-mentioned defects, the embodiments of this disclosure provide a pipe connection forged flange, which solves the technical problem in the prior art that when these external forces cause the flange to bend, deformation is easily generated between the two flanges. This deformation not only damages the structural integrity of the flange itself and reduces its structural strength, but also seriously affects the sealing performance of the entire device.

[0007] According to one aspect, at least one embodiment of this disclosure provides a pipe connection forged flange, comprising:

[0008] A pair of pipes and a flange, wherein the flange is disposed between the pipes;

[0009] A fixed connection assembly is disposed between the pipe and the flange;

[0010] A reinforcing bending component is disposed outside the pipe and the flange;

[0011] The fixed connection assembly includes a pair of mating grooves, which are formed on both sides of the flange. A sealing protrusion is provided on the side end face of the pipe, and the sealing protrusion is inserted into the mating groove. Several internally threaded pipes are provided on both sides of the flange.

[0012] As a further technical solution, several circular grooves are formed around the side surface of the pipe. The inside of the circular grooves is a stepped through structure. One end of the internally threaded pipe is inserted into the circular groove, and a bolt is inserted into the circular groove. The bolt is screwed into the internally threaded pipe.

[0013] As a further technical solution, the reinforcement and bending-resistant component includes a pair of clamps, which are attached to both sides of the pipe. Each end of the clamps is provided with an extension plate, and the opposite extension plates are connected by a pull rod through a threaded connection.

[0014] As a further technical solution, a reinforcing rod is rotatably connected to the outside of the clamping plate via a pin. An opening is provided on the side surface of the reinforcing rod, and an adjusting screw is rotatably connected inside the opening. Pressure blocks are provided at both ends of the adjusting screw.

[0015] As a further technical solution, a pair of positioning slots are provided on the side surface of the pipe, and the pressure blocks are all inserted into the positioning slots. A screwing block is provided at one end of the adjusting screw.

[0016] As a further technical solution, the thread directions at both ends of the pull rod and the thread directions at both ends of the adjusting screw are both positive and negative spirals.

[0017] As a further technical solution, both the pull rod and the screw block have polygonal surfaces.

[0018] As a further technical solution, a pair of guide rods are provided inside the opening, and the guide rods are slidably connected to the pressure block.

[0019] As a further technical solution, the portion of the clamp that fits against the outer wall of the pipe is an arc-shaped transition structure.

[0020] The beneficial effects of the embodiments disclosed herein are as follows:

[0021] 1. The beneficial effects of the fixed connection assembly in this disclosure are that the mating groove and the sealing protrusion fit tightly, initially preventing media leakage and defining the connection position. The internally threaded pipe, the circular groove, and the bolt work together, and the tightening force generated when the bolts are tightened ensures a tight connection between the pipe and the flange. This design enhances the stability and sealing of the connection. At the same time, the assembly is easy to install, achieving a reliable connection without complex operations. Whether under normal operating conditions or in environments with some vibration, it ensures the stability of the pipeline connection and effectively reduces media leakage problems caused by loose connections.

[0022] 2. The reinforcing bending-resistant component disclosed herein offers significant advantages. The arc-shaped transition structure of the clamping plate against the outer wall of the pipe increases the contact area and improves the firmness of the fixation. The positive and negative spiral threads at both ends of the tie rod allow the extension plate to move closer or further away synchronously during rotation, quickly clamping or releasing the pipe. The polygonal structure of the tie rod and the screw block facilitates operation with tools. The adjusting screw, pressure block, positioning slot, and guide rod work together to effectively disperse external forces when the pipe is subjected to bending forces. The pressure block provides support within the positioning slot, and the guide rod ensures stable movement of the pressure block. Overall, this enhances the bending resistance of the pipe connection, prevents bending deformation caused by external forces, and extends the service life of the pipe connection system.

[0034] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0035] As shown in Figures 1-4, a pipe connection forging flange according to an embodiment of this disclosure is illustrated, comprising:

[0036] A pair of pipes 1 and a flange 2, wherein the flange 2 is disposed between the pipes 1;

[0037] A fixed connection assembly 3 is disposed between the pipe 1 and the flange 2;

[0038] A reinforcing bending component 4 is disposed outside the pipe 1 and the flange 2;

[0039] The fixed connection assembly 3 includes a pair of mating grooves 3-1, which are formed on both sides of the flange 2. A sealing protrusion 3-2 is provided on the side end face of the pipe 1, and the sealing protrusion 3-2 is inserted into the mating groove 3-1. Several internally threaded pipes 3-3 are provided on both sides of the flange 2. Several circular grooves 3-4 are formed around the side surface of the pipe 1. The circular grooves 3-4 have a stepped through structure inside. One end of the internally threaded pipe 3-3 is inserted into the circular groove 3-4. A bolt 3-5 is inserted into the circular groove 3-4 and screwed into the internally threaded pipe 3-3.

[0040] In some examples, during the connection of pipes 1, a fixed connection assembly 3 is designed to securely connect the two pipes 1 together. This assembly includes a pair of mating grooves 3-1 on both sides of the flange 2, which cooperate with the sealing protrusions 3-2 on the side end face of the pipe 1. The sealing protrusions 3-2 are inserted into the mating grooves 3-1, forming a preliminary sealing and positioning structure, effectively preventing gas or liquid leakage, and ensuring the accuracy of the connection position of the pipes 1. Several internally threaded pipes 3-3 on both sides of the flange 2 are adapted to the stepped circular grooves 3-4 on the side surface of the pipe 1. One end of the internally threaded pipe 3-3 is inserted into the mating groove 3-1, and bolts 3-5 inserted in the mating groove 3-1 are screwed into the internally threaded pipe 3-3. By tightening the bolts 3-5, the flange 2 and the pipe 1 can be firmly fixed together, making the pipe 1 and the flange 2 fit tightly together, achieving a stable and secure connection between the two pipes 1.

[0041] Through the coordinated work of components such as the mating groove 3-1, the sealing protrusion 3-2, the internal threaded pipe 3-3, the mating groove 3-1, and the bolt 3-5, the fixed connection assembly 3 achieves the function of tightly and firmly connecting the two pipes 1.

[0042] As shown in Figures 1 to 4, this embodiment proposes that the reinforcing and bending-resistant component 4 includes a pair of clamping plates 4-1, which are attached to both sides of the pipe 1. Extension plates 4-2 are provided at both ends of the clamping plates 4-1. A pull rod 4-3 is threadedly connected between the opposite extension plates 4-2. A reinforcing rod 4-4 is rotatably connected to the outside of the clamping plates 4-1 by a pin. An opening 4-5 is provided on the side surface of the reinforcing rod 4-4. An adjusting screw 4-6 is rotatably connected in the opening 4-5. Pressure blocks 4-7 are provided at both ends of the adjusting screw 4-6. A pair of positioning slots 4-8 are provided on the side surface of the pipe 1. The pressure blocks 4-7 are inserted into the positioning slots 4-8. A screwing block 4-9 is provided at one end of the adjusting screw 4-6.

[0043] In some examples, to ensure the stability of the pipe 1 connection, a fixed connection assembly 3 is further designed to enhance the firmness between the two pipes 1 and make it resistant to bending. This assembly includes a pair of clamps 4-1 that fit against both sides of the pipe 1. Extension plates 4-2 at both ends of the clamps 4-1 are connected to the opposite extension plates 4-2 by threaded rods 4-3, which can firmly fix the clamps 4-1 to the pipe 1, providing initial reinforcement. A reinforcing rod 4-4 is rotatably connected to the outside of the clamps 4-1 by a pin, and an adjustment rod is rotatably connected to the opening 4-5 on its side surface. The screw 4-6 and the pressure blocks 4-7 set at both ends of the adjusting screw 4-6 cooperate with a pair of positioning slots 4-8 opened on the side surface of the pipe 1. By rotating the screw block 4-9 at one end of the adjusting screw 4-6, the pressure block 4-7 can be moved in the positioning slots 4-8 and pressed against the pipe 1, so that the reinforcing rod 4-4 is tightly connected to the pipe 1. When the pipe 1 is subjected to bending force, this structure can effectively disperse the external force, enhance the strength of the connection part of the pipe 1, prevent the pipe 1 from bending and deforming due to force, thereby strengthening the firmness between the two pipes 1 and achieving the purpose of anti-bending.

[0044] Through the coordinated work of components such as clamping plate 4-1, extension plate 4-2, tie rod 4-3, reinforcing rod 4-4, through port 4-5, adjusting screw 4-6, pressure block 4-7, positioning slot 4-8, and screwing block 4-9, the reinforcement and anti-bending component 4 achieves the function of strengthening the connection of pipe 1 and improving its anti-bending ability.

[0045] For example, as shown in Figure 1, the thread directions at both ends of the pull rod 4-3 and the thread directions at both ends of the adjusting screw 4-6 are both positive and negative helical.

[0046] In some examples, by using opposite thread directions, the connected parts can be driven to move synchronously toward each other or toward each other, achieving the effect of synchronous control.

[0047] For example, as shown in Figure 1, the surfaces of the pull rod 4-3 and the screw block 4-9 are both polygonal structures.

[0048] In some examples, the polygonal structure facilitates the use of a wrench to clamp and tighten the screw rod 4-3 and the screw block 4-9.

[0049] For example, as shown in Figure 1, a pair of guide rods 5 are provided inside the opening 4-5, and the guide rods 5 are slidably connected to the pressure block 4-7.

[0050] In some examples, the guide rod 5 provides sliding stability for the pressure block 4-7, ensuring accurate insertion into the positioning slot 4-8.

[0051] For example, as shown in Figure 1, the part of the clamp 4-1 that fits against the outer wall of the pipe 1 is an arc-shaped transition structure.

[0052] In some examples, the curved transition structure allows for a tight fit with the outer wall of pipe 1, improving the stability of the fixation.

[0053] In actual use: First, place the flange 2 between the two pipes 1, so that the sealing protrusion 3-2 on the side end face of the pipe 1 is accurately inserted into the mating groove 3-1 on both sides of the flange 2 to complete the initial positioning and sealing. Then, insert the internal threaded pipe 3-3 into the circular groove 3-4 on the side surface of the pipe 1, and then screw the bolt 3-5 through the circular groove 3-4 into the internal threaded pipe 3-3. Tighten the bolt 3-5 to further secure the connection between the pipe 1 and the flange 2. Then, attach a pair of clamping plates 4-1 to both sides of the pipe 1 respectively. Rotate the pull rod 4-3, and use its positive and negative spiral threads to bring the extension plates 4-2 at both ends of the clamping plate 4-1 closer to each other, thereby clamping the pipe 1. Then, rotate the reinforcing rod 4-4 so that the pressure blocks 4-7 at both ends of the adjusting screw 4-6 are aligned with the positioning slots 4-8 on the side surface of the pipe 1. Rotate the screwing block 4-9 to adjust the adjusting screw 4-6. Under the guidance of the guide rod 5, the pressure blocks 4-7 are tightly inserted into the positioning slots 4-8.

Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
