Technical Field
[0001] The utility model relates to the technical field of pipeline repair, in particular to a 360° internal steam joint of a FIPP thermoplastic lining forming repair pipe. Background Technique
[0002] The FIPP thermoplastic lining forming repair technology is a technology that uses a new type of polymer thermoplastic material with the characteristics of heating and softening and cooling and forming to repair pipelines in a trenchless manner. The basic principle of this technology is to prefabricate the lining pipe into a specific shape (such as "I" shape or "C" shape) in the factory and then transport it to the construction site. At the site, the pipe material is heated and softened by hot steam, and then quickly pulled into the pipeline to be repaired through an inspection well. The two ends are blocked by a high-temperature resistant airbag, and hot steam is filled to expand the lining pipe to closely fit with the original pipeline. Subsequently, cold air is injected to cool down, and the lining material is cooled and hardened to form a new lining pipe tightly attached to the pipe wall, realizing the overall repair of the pipeline. During the FIPP thermoplastic lining forming repair process, the 360° internal steam joint is a key link to ensure the tight connection between the lining pipe and the original pipeline. The existing 360° internal steam joints of FIPP thermoplastic lining forming repair pipes can basically meet the daily use requirements, but there are still some deficiencies that need to be improved.
[0003] When the existing 360° internal steam joints of FIPP thermoplastic lining forming repair pipes are in use, bolts are usually used to connect the flange and the internal steam joint. Flange connection requires relatively high skills and experience accumulation. Otherwise, it is easy to cause the danger of insecure pipeline connection and air leakage. For this reason, we propose a 360° internal steam joint of a FIPP thermoplastic lining forming repair pipe to solve the above problems. Content of the Utility Model

First springs are wound around the surfaces of the guide rods. Pull handles are provided on the surfaces of the sliders facing away from the heating pipe. Insert blocks are provided on the surfaces of the sliders facing the heating pipe. Sockets are opened on the outer walls of the heating pipe.
[0006] As a further preference of the present technical solution, a protection component is provided on the outer wall of the limiting component. The protection component includes two movable bins provided on the outer walls of the fixed frames. Connecting rods are vertically arranged on the inner walls of the movable bins. Second springs are wound around the connecting rods. Guide blocks are slidably arranged on the connecting rods. Protective covers are provided on the surfaces of the guide blocks facing the internal steam joint. Six cavities are opened in each of the protective covers. Threaded rods are provided on the surfaces of the guide blocks facing away from the internal steam joint. Threaded blocks are threadedly connected to the threaded rods. Limit grooves are opened on the surfaces of the movable bins corresponding to the inner end surfaces of the threaded blocks.
[0007] As a further preference of the present technical solution, the part of the insert block inserted into the socket is designed in a rectangular shape, and the socket is opened as a counterbore matching part of the insert block.

[0012] The utility model provides a 360° internal steam joint for a FIPP thermoplastic lining forming repair pipe, which has the following beneficial effects:
[0013] 1. By means of the limiting component arranged between the internal steam joint and the heating pipe, the plug block is aligned with the slot, and then the restoring force of the first spring is used to push the slider to slide on the guide rod, driving the plug block to slide into the slot, so as to position the internal steam joint and the heating pipe, making the thread grooves in the internal steam joint and the heating pipe align with the bolts, which is convenient for the staff to connect the internal steam joint and the heating pipe, effectively reducing the installation error between the internal steam joint and the heating pipe, and further improving the installation efficiency of the staff.

[0022] By aligning the insert block 57 with the slot groove 58, and then using the restoring force of the first spring 55 to push the slider 54 to slide on the guide rod 52 and drive the insert block 57 to slide into the slot groove 58, the purpose of positioning the internal steam joint 1 and the heating pipe 2 is achieved, so that the thread grooves in the internal steam joint 1 and the heating pipe 2 are aligned with the bolts 7, which is convenient for the staff to connect the internal steam joint 1 and the heating pipe 2, effectively reducing the installation error between the internal steam joint 1 and the heating pipe 2 and further improving the installation efficiency of the staff.
[0023] In other embodiments, a protective component 6 is provided on the outer wall of the limiting component 5. The protective component 6 includes two movable bins 61 arranged on the outer walls of the fixed frames 51. Connecting rods 62 are vertically arranged on the inner walls of the movable bins 61.

[0035] The utility model provides a 360° internal steam joint for a FIPP thermoplastic lining forming and repairing pipe. The specific working principle is as follows:
[0036] During use, first, pull the two sets of pull handles 56 in the direction away from the internal steam joint 1, so that the pull handles 56 drive the sliders 54 to slide on the guide rods 52. At the same time, the sliders 54 slide synchronously in the sliding grooves 53 and drive the insertion blocks 57 to move. Meanwhile, the sliders 54 continuously squeeze the first springs 55, causing the first springs 55 to deform. Then, place the heating pipe 2 on the internal steam joint 1, align the insertion blocks 57 with the slots 58, and then release the pull handles 56. At this time, the restoring force of the first springs 55 pushes the sliders 54 to slide on the guide rods 52, and the sliders 54 drive the insertion blocks 57 to slide into the slots 58. Then, connect the internal steam joint 1 and the heating pipe 2 through bolts 7. Next, rotate the internal steam joint 1 threadedly into the screw port 4 to connect the internal steam joint 1 with the lining pipe 3. Then, fill the heating pipe 2 with hot steam, so that the hot steam of the heating pipe 2 enters the lining pipe 3 through the internal steam joint 1, causing the lining pipe 3 to expand and fit tightly with the original pipe. Subsequently, inject cold air to cool down, so that the lining material cools and hardens to form a lining pipe 3 that adheres tightly to the pipe wall, realizing the overall repair of the pipe.
[0037] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
