Description

Technical Field

[0001] This utility model relates to the field of pipe connectors, and in particular to an anti-detachment sealing flange. Background Technology

[0002] The use of connecting components in piping systems is very important, therefore flanges play an important role in pipe connections. Flange connections are a common connection method in piping engineering, especially for high-pressure and high-temperature piping systems, and the connection of flanges affects the stability of the pipeline.

[0003] Chinese patent application number CN201220396323.3 provides a pipe connection flange. This solution installs a sealing ring in the stepped groove around the through hole in the middle of the flange. Due to the design of the stepped groove, the pipe connection leakage caused by the error when the flanges are connected between pipes is effectively avoided, thus improving the sealing performance.

[0004] Existing connecting flanges have certain drawbacks in use. First, because different connecting flanges are used in different environments for the pipes they connect, most existing connecting flanges rely on bolts for a single connection. This makes them extremely prone to detachment when the pipes are used in unstable environments, resulting in reduced stability of the connecting flanges. To address this, we propose an anti-detachment sealing flange. Utility Model Content

[0005] To overcome the shortcomings of existing technologies, the purpose of this utility model is to provide an anti-detachment sealing flange. By setting an adjusting ring and a positioning ring, after flange one and flange two are connected, a pair of reinforcing rings are connected by positioning components, thereby forming a reinforced connection structure on the outside of the connecting pipe. At the same time as the connection, the adjusting ring and the connecting ring are adjusted in position. After being adjusted to the appropriate position, the pair of positioning rings are attached to the outside of the connected flange assembly. When the positioning ring drives the sealing ring to adhere to the outside of the flange assembly, under the force of the movable rod and the elastic ring, the movable rod can be adjusted in position to drive the positioning ring, so that the positioning ring and the sealing ring are tightly attached to the outside of the flange assembly. This significantly improves the sealing effect of the connection structure, avoids the leakage problem caused by poor sealing in traditional flange connections, and the adjustable position design allows the positioning ring and the sealing ring to be adjusted according to actual needs, improving the anti-detachment effect of the flange connection and increasing the sealing performance.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A type of anti-detachment sealing flange includes a flange one, a flange two movably connected to the outer end of the flange one, a screw one threadedly connected to the inner end of the flange two, a pipe one fixedly connected to the outer end of the flange one, reinforcing rings movably connected to both sides of the flange one, an adjusting ring fixedly connected to the outer end of one side of the reinforcing ring, a movable rod fixedly connected to the inner end of the adjusting ring, a positioning ring slidably connected to the outer end of the movable rod, and a sealing ring fixedly connected to the outer end of the positioning ring.

[0008] By installing adjusting rings and positioning rings, the anti-loosening effect of the flange connection is improved, and the sealing performance is also increased.

[0009] Furthermore, the inner end of the positioning ring is provided with an adjustment groove, and the outer end of the movable rod is fitted with an elastic ring.

[0010] The practicality of this positioning ring is further improved by installing an elastic ring.

[0011] Furthermore, a guide ring is slidably connected to the inner end of the adjustment groove.

[0012] The adjustment effect of the positioning ring can be further improved by installing a guide ring.

[0013] Furthermore, the guide ring is located at the outer end of the movable rod, and a guide head is fixedly connected to the front end of the movable rod.

[0014] By installing a guide head, which works in conjunction with a guide ring, the movable rod can have multiple guiding structures, further improving its adjustment effect.

[0015] Furthermore, a pair of reinforcing blocks are fixedly connected to the outer ends of the pair of reinforcing rings, and a second pipe is fixedly connected to the outer end of the second flange.

[0016] By installing reinforcing blocks, each of the two reinforcing rings is equipped with a reinforcing block on its outside. The two reinforcing blocks are connected by a positioning component, making it easy to connect the reinforcing rings.

[0017] Furthermore, the inner end of the reinforcing block is threaded with a positioning element.

[0018] By installing positioning elements, the stability of the connection between the flange assemblies can be further improved.

[0019] Furthermore, an extension block is slidably connected to the inner end of the adjustment ring, and sliders are slidably connected to both ends of the extension block. A guide groove is provided at the inner end of the adjustment ring.

[0020] The protective effect of this anti-detachment sealing flange is further improved by installing adjusting rings and extension blocks.

[0021] Furthermore, a connecting ring is fixedly connected to the other end of the extension block, and one end of the connecting ring is connected to a reinforcing ring at one end.

[0022] The protective effect of the flange assembly can be increased by installing a connecting ring, which, together with an adjusting ring.

[0023] In summary, this utility model has the following beneficial effects:

[0024] 1. By setting adjustment rings and positioning rings, after flange one and flange two are connected, a pair of reinforcing rings are connected by positioning components, thereby forming a reinforced connection structure on the outside of the connected pipe. At the same time as the connection, the adjustment rings and connecting rings are adjusted in position. After being adjusted to the appropriate position, a pair of positioning rings are attached to the outside of the connected flange assembly. When the positioning rings drive the sealing rings to adhere to the outside of the flange assembly, under the force of the movable rod and elastic ring, the movable rod can be adjusted in position to drive the positioning rings, so that the positioning rings and sealing rings are tightly attached to the outside of the flange assembly. This significantly improves the sealing effect of the connection structure, avoids the leakage problem caused by poor sealing in traditional flange connections, and the adjustable position design allows the positioning rings and sealing rings to be adjusted according to actual needs, improving the anti-detachment effect of the flange connection and increasing the sealing performance.

[0025] 2. By setting an elastic ring, the elastic ring can move together with the adjustment of the movable rod. When the positioning ring contacts the outside of the flange, the elastic ring works with the movable rod to adjust its position, making the positioning ring easy to adjust and the position easy to reset, thus further improving the practicality of the positioning ring.

[0026] 3. By setting an adjusting ring and an extension block, when a pair of flange assemblies are connected, the adjusting ring works with the connecting ring to form a protective structure on the outside of the flange assembly. The connecting ring can be adjusted in position by sliding the extension block inside the adjusting ring. This allows the flange assembly to have a protective structure on the outside, and the protective structure can be adjusted according to the actual installation position. When the flange assembly is connected, it avoids direct impact from external forces, further improving the protective effect of the anti-detachment sealing flange. Attached Figure Description

Detailed Implementation

[0033] The present invention will be further described in detail below with reference to the accompanying drawings.

[0034] Identical parts are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "bottom surface," "top surface," "inner," and "outer" refer to directions toward or away from the geometric center of a specific part, respectively.

[0035] Reference Figure 1-5 As shown, a preferred embodiment of the present invention is a non-detachable sealing flange, including flange 1, flange 2 3 movably connected to the outer end of flange 1, screw 4 threadedly connected to the inner end of flange 2 3, pipe 2 fixedly connected to the outer end of flange 1, reinforcing rings 6 movably connected to both sides of flange 1, adjusting ring 9 fixedly connected to the outer end of one side of reinforcing ring 6, movable rod 12 fixedly connected to the inner end of adjusting ring 9, positioning ring 13 slidably connected to the outer end of movable rod 12, and sealing ring 14 fixedly connected to the outer end of positioning ring 13.

[0036] Reference Figure 3-4 As shown, the inner end of the positioning ring 13 is provided with an adjustment groove 15, and the outer end of the movable rod 12 is fitted with an elastic ring 16.

[0037] Reference Figure 3-4 As shown, a guide ring 18 is slidably connected to the inner end of the adjusting groove 15.

[0038] Reference Figure 4 As shown, the guide ring 18 is located at the outer end of the movable rod 12, and the front end of the movable rod 12 is fixedly connected to the guide head 17.

[0039] A pair of reinforcing rings 6 are connected by positioning element 8, thereby forming a reinforced connection structure on the outside of the connecting pipe. Simultaneously, adjusting ring 9 and connecting ring 11 are adjusted to their proper positions. After adjustment, a pair of positioning rings 13 adhere to the outside of the connected flange assembly. When the positioning rings 13 drive the sealing ring 14 to adhere to the outside of the flange assembly, under the force of the movable rod 12 and the elastic ring 16, the elastic ring 16 can move together with the adjustment of the movable rod 12. When the positioning rings 13 contact the outside of the flange, the elastic ring 16, in conjunction with the movable rod 12, adjusts its position, allowing for convenient positioning and resetting of the positioning rings 13. The position adjustment is also convenient. The guide ring 18 can move simultaneously with the movement of the movable rod 12. The moving guide ring 18 slides at the inner end of the adjustment groove 15. The adjustment groove 15 guides and restricts it, effectively preventing the guide ring 18 and the movable rod 12 from falling off or shifting during movement. The movable rod 12 can be adjusted to drive the positioning ring 13, so that the positioning ring 13 and the sealing ring 14 fit tightly on the outside of the flange assembly, which significantly improves the sealing effect of the connection structure and avoids the leakage problem caused by poor sealing in traditional flange connections. Moreover, the adjustable position design allows the positioning ring 13 and the sealing ring 14 to adjust their tightness according to actual needs.

[0040] Reference Figure 1-2 As shown, further, a pair of reinforcing blocks 7 are fixedly connected to the outer ends of a pair of reinforcing rings 6, and a pipe 5 is fixedly connected to the outer end of flange 2 3.

[0041] Reference Figure 1 As shown, the inner end of the reinforcing block 7 is further threaded with a positioning element 8.

[0042] Reference Figure 1 , Figure 2 and Figure 5 As shown, further, an extension block 10 is slidably connected to the inner end of the adjusting ring 9, and sliders 101 are slidably connected to both ends of the extension block 10. A guide groove 102 is provided at the inner end of the adjusting ring 9.

[0043] Reference Figure 1 As shown, the other end of the extension block 10 is further fixedly connected to a connecting ring 11, one end of which is connected to a reinforcing ring 6 at one end.

[0044] By installing a pair of reinforcing rings 6, each of which is equipped with a reinforcing block 7, and connecting the pair of reinforcing blocks 7 through a positioning element 8, a connecting and reinforcing structure can be formed between the pair of reinforcing rings 6. This structure forms a reinforcing structure on the outside of the flange. When a pair of flange assemblies are connected, the adjusting ring 9 cooperates with the connecting ring 11 to form a protective structure on the outside of the flange assembly. The connecting ring 11 can be adjusted in position by sliding the extension block 10 inside the adjusting ring 9. This allows the flange assembly to have a protective structure on the outside, and the distance of the protective structure can be adjusted according to the actual installation position, so that the flange assembly is protected from direct impact from external forces when it is connected.

[0045] Specific implementation process: When connecting the flange assembly, flange 1 and flange 3 are first connected by screw 4. After connection, a pair of reinforcing blocks 7 are passed through by positioning piece 8, which allows a connection and reinforcement structure between the pair of reinforcing rings 6. The reinforcing rings 6 are detachable, which is convenient for positioning or separation from the pipeline assembly. After the positioning piece 8 is connected, a reinforcement structure can be formed on the outside of the flange. When the reinforcing rings 6 are connected, the adjusting ring 9 cooperates with the connecting ring 11 to form a protective structure on the outside of the flange assembly. The connecting ring 11 can be adjusted in position by sliding the extension block 10 inside the adjusting ring 9. This allows the flange assembly to have a protective structure on the outside, and the distance of the protective structure can be adjusted according to the actual installation position, so that the flange assembly is connected without direct impact from external forces.

[0046] After adjusting ring 9 and connecting ring 11 are adjusted to the appropriate position, a pair of positioning rings 13 are attached to the outside of the connected flange assembly. When the positioning rings 13 drive the sealing rings 14 to adhere to the outside of the flange assembly, under the force of the movable rod 12 and the elastic ring 16, the movable rod 12 can be adjusted to move the positioning rings 13. The elastic ring 16 can move together with the adjustment of the movable rod 12. When the positioning rings 13 contact the outside of the flange, the elastic rings 16 cooperate with the movable rod 12 to adjust their position. This makes it convenient to adjust and position the positioning rings 13, and also convenient to reset and adjust their position. This ensures that the positioning rings 13 and the sealing rings 14 are tightly attached to the outside of the flange assembly, which significantly improves the sealing effect of the connection structure and avoids the leakage problem caused by poor sealing in traditional flange connections. Moreover, the adjustable position design allows the positioning rings 13 and the sealing rings 14 to adjust their tightness according to actual needs, which improves the sealing connection effect of the assembly.
