In the process of transporting high-temperature gases, the pipelines are easily deformed under high temperature conditions, and the safety accidents caused are becoming more and more frequent.

[0003] At present, most high-temperature gas transmission pipelines use methods such as reinforcing pipeline supports, building Π-shaped bends, and installing metal compensators to reduce pipeline deformation. Although these methods have reduced material deformation to a certain extent, the effect is not obvious, and the cost is constantly increasing, which is not conducive to the production efficiency of the enterprise.

The two limiting nuts are used to limit the two adjusting plates, and the movement range of the adjusting plates can be changed by the two adjusting nuts, so that the appropriate movement range of the adjusting plates can be set in advance according to the deformation amount of the high-temperature gas transmission pipeline. The deformation of the high-temperature gas transmission pipeline is controllable within a reasonable range, ensuring the safety of the transportation pipeline.

[0009] Further preferably, the two ends of the ceramic fiber cloth are respectively fixedly connected to the symmetrically arranged movable plate and the adjustment plate through connecting pieces. The ceramic fiber cloth itself has a certain ductility and can move left and right along with the movable plate and the adjustment plate on the movable connecting rod of the adjustment assembly.

[0010] Further preferably, the ends of the symmetrically arranged end connectors that are away from each other are respectively provided with connecting flanges, and the circumferential surfaces of the connecting flanges are evenly provided with a plurality of connecting holes. The two end connectors are connected to the high-temperature gas delivery pipeline through the multiple connecting holes evenly provided on the circumferential surfaces of the connecting flanges.

[0011] Further preferably, the movable plate, the partition plate and the ceramic fiber cloth surround and form a heat-insulating cavity, and the interior of the heat-insulating cavity is filled with heat-insulating cotton.

[0012] Preferably, the outer side of the connection between the end connector and the movable plate is provided with reinforcing ribs, and the reinforcing ribs are in an annular structure as a whole.

The overall safety is high.

[0015] The flexible pipe flexible connection joint is connected between two pipes, and the overall structure is relatively simple. Compared with methods such as reinforcing pipe supports, the flexible pipe flexible connection joint is easy to make, relatively low in cost, and has a wide range of uses.

[0020] See also Figure 1-Figure 2 , the utility model provides a technical solution:

[0021] A flexible pipe soft connection joint, comprising symmetrically arranged end connectors 1, the end connectors 1 are respectively connected with movable plates 3 on the sides close to each other, a plurality of partitions 4 are arranged between the movable plates 3 close to the end connectors 1, a ceramic fiber cloth 6 is arranged between the movable plates 3 away from the end connectors 1, an adjustment plate 8 is arranged outside the movable plates 3, and a plurality of adjustment components are also arranged on the surface of the adjustment plate 8;

[0022] The adjustment component includes a plurality of movable connecting rods 9 uniformly penetrating the surface of the adjustment plate 8, and two adjusting nuts 10 and two limiting nuts 11 are symmetrically screwed on the surface of each movable connecting rod 9. The adjusting nuts 10 and limiting nuts 11 are respectively arranged on both sides of the adjustment plate 8, and the two adjusting nuts 10 are arranged between the two adjustment plates 8, and the two limiting nuts 11 are respectively arranged on the outside of the two adjustment plates 8. The two limiting nuts 11 are used to limit the two adjustment plates 8, and the two adjusting nuts 10 can change the movement range of the adjustment plate 8, so as to set the appropriate movement range of the adjustment plate 8 in advance according to the deformation amount of the high-temperature gas transmission pipeline. The deformation of the high-temperature gas transmission pipeline can be controlled within a reasonable range to ensure the safety of the transportation pipeline.

[0023] In the present invention, both ends of the ceramic fiber cloth 6 are respectively fixedly connected to the symmetrically arranged movable plate 3 and the adjusting plate 8 through the connecting piece 7. The ceramic fiber cloth 6 itself has a certain ductility and can move left and right with the movable plate 3 and the adjusting plate 8 on the movable connecting rod 9 of the adjusting assembly.

[0024] In the present invention, the ends of the symmetrically arranged end connectors 1 that are far away from each other are respectively provided with connecting flanges 2, and a plurality of connecting holes are evenly arranged on the circumferential surface of the connecting flanges 2. Through the plurality of connecting holes evenly arranged on the circumferential surface of the connecting flanges 2, the two end connectors 1 are connected to the high-temperature gas delivery pipeline.

[0025] In the utility model, the movable plate 3, the partition plate 4 and the ceramic fiber cloth 6 surround and form a heat preservation cavity 5, and the interior of the heat preservation cavity 5 is filled with heat preservation cotton.

[0026] In the present invention, a reinforcing rib 12 is provided outside the connection between the end connector 1 and the movable plate 3, and the reinforcing rib 12 is annular in structure. The reinforcing rib 12 can strengthen the structure of the connection between the end connector 1 and the movable plate 3, thereby ensuring that the device can be used for a long time.

[0027] Embodiment: When in use, first connect the two end connectors 1 to the high-temperature gas delivery pipeline through a plurality of connection holes evenly arranged on the circumferential surface of the connecting flange 2. During installation, ensure that the opening direction of the innermost baffle 4 is away from the end of the end connector 1 that is close to the flow direction of the high-temperature gas. The movable plate 3, baffle 4 and ceramic fiber cloth 6 surround and form an insulation cavity 5, and the insulation cavity 5 is filled with insulation cotton. Then, according to the deformation of the high-temperature gas delivery pipeline, adjust the position of the limit nut 11 and the adjustment nut 10 on the movable connecting rod 9 to ensure that the reserved movement range of the adjustment plate 8 can meet the deformation of the high-temperature gas delivery pipeline. During long-term use, according to the deformation of the material, the end of the high-temperature gas delivery pipeline connected to the end connector 1 creeps in the direction of the high-temperature gas under the action of high temperature, and the creep gradually accumulates at the flexible pipe flexible connection joint. The movable plate 3 can move to both sides at the same time under the drive of the high-temperature gas, and the entire adjustment component is in an active state and can move with the movement of the high-temperature gas, thereby transforming "preventing deformation" into the current "controlling deformation", setting a specific deformation direction and deformation threshold for the transportation of the high-temperature gas delivery pipeline, thereby achieving effective control of the deformation of the high-temperature gas delivery pipeline, eliminating the metal creep of the high-temperature gas delivery pipeline under high temperature, and keeping the deformation of the high-temperature gas delivery pipeline "within a safe range". At the same time, the multi-layer partitions 4 are cross-arranged to form a maze structure, and the movable plate 3 and the ceramic fiber cloth 6 are combined to form an insulation cavity 5, and the insulation cavity 5 is filled with insulation cotton. The entire flexible pipe soft connection joint can prevent the leakage of high-temperature gas, improve the sealing of the entire high-temperature gas delivery pipeline, and also have a good insulation effect.
