Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] like Figures 1 to 5 As shown, the utility model provides a high-pressure combined sealing ring, including a fixed chamber 1, the left and right sides of the fixed chamber 1 are both threadedly connected with mounting bolts 2, the surface of the mounting bolts 2 is threadedly connected with a connecting chamber 3, the right side of the connecting chamber 3 is fixedly connected with a piston cylinder 4, the inner cavity of the piston cylinder 4 is fixedly connected with a fixing spring 5, the left side of the fixing spring 5 is fixedly connected with a piston plate 6, the right side of the piston plate 6 is fixedly connected with a piston rod 7, the right side of the piston rod 7 is fixedly connected with a movable reflective reminder plate 8, and the right side of the piston cylinder 4 is fixedly connected with a fixed reflective reminder plate 9;

[0022] When leakage occurs through the pipeline, the gas enters the inner cavity of the connecting chamber 3. When there is more gas, it will enter the inner cavity of the piston cylinder 4, thereby pushing the piston plate 6 to move, and the piston plate 6 drives the piston rod 7 to move, and the piston rod 7 drives the movable reflective reminder plate 8 to move, so that the movable reflective reminder plate 8 and the fixed reflective reminder plate 9 are staggered, and then the red reflective stickers of the movable reflective reminder plate 8 and the fixed reflective reminder plate 9 leak out, thereby reminding the inspection personnel, so that when a slight leak occurs, the inspection personnel can inspect more intuitively, reducing the labor intensity of the inspection personnel.

[0023] Among them, a sealing ring 11 is placed in the inner cavity of the fixed bin 1, a fixing ring 12 is fixedly connected to the inner cavity of the sealing ring 11, a threaded ring 13 is fixedly connected to the side of the fixed bin 1 away from the sealing ring 11, a threaded rod 14 is threadedly connected to the inner cavity of the threaded ring 13, and a threaded ring 2 15 is fixedly connected to the middle of the fixing ring 12;

[0024] When the sealing ring 11 is damaged, the threaded rod 14 is rotated, and the threaded ring 13 is engaged with the threaded rod 14, so that the threaded rod 14 rotates and moves upward, and then the threaded rod 14 is screwed out from the inner cavity of the threaded ring 2 15, and then the limit of the fixing ring 12 is released, so that the sealing ring 11 can fall off from the inner cavity of the fixed bin 1, and then the sealing ring 11 is replaced separately, thereby avoiding the need to replace the entire sealing ring 11 when it is damaged.

[0025] The inner cavity of the fixed bin 1 is fixedly connected with a heat insulation board 10, and the heat insulation board 10 is located at the center of the inner cavity of the sealing ring 11;

[0026] Since the heat insulation board 10 is located at the center of the inner cavity of the sealing ring 11, the heat insulation board 10 can be separated from the pipeline, thereby isolating the heat of the pipeline, thereby preventing the sealing ring 11 from being overheated.

[0027] The piston cylinder 4 is connected to the inner cavity of the connecting chamber 3, and the piston rod 7 passes through the piston cylinder 4 and is fixedly connected to the movable reflective reminder plate 8;

[0028] The piston cylinder 4 is connected to the inner cavity of the connecting chamber 3, so that when there is more gas in the inner cavity of the connecting chamber 3, it can enter the inner cavity of the piston cylinder 4 through the connecting chamber 3, thereby pushing the piston plate 6 in the inner cavity of the piston cylinder 4 to move, and then driving the movable reflective reminder plate 8 on the right side of the piston rod 7 to move, so that the movable reflective reminder plate 8 and the fixed reflective reminder plate 9 are staggered, and then the red reflective stickers of the movable reflective reminder plate 8 and the fixed reflective reminder plate 9 leak out, reminding the staff of the leakage here.

[0029] The piston plate 6 is attached to the inner wall of the piston cylinder 4, and the piston rod 7 is located at the center of the inner cavity of the fixed spring 5;

[0030] The piston plate 6 is fitted to the inner wall of the piston cylinder 4, so that when air enters the inner cavity of the piston cylinder 4, it can stably push the piston plate 6 to move, and then the piston plate 6 drives the moving reflective reminder plate 8 on the right side of the piston rod 7 to move. Then, through the setting of the fixed spring 5, when the leakage is discovered by the inspection personnel, the leakage point of the pipeline is processed and the air in the inner cavity of the piston cylinder 4 is discharged. At this time, the piston plate 6 can be reset by the fixed spring 5, and the piston plate 6 can be positioned and guided by the fixed spring 5.

[0031] The top of the threaded rod 14 is fixedly connected with a swivel 16, and the threaded rod 14 is threadedly connected to the inner cavity of the threaded ring 15;

[0032] Through the swivel ring 16 at the top of the threaded rod 14, it is convenient for the user to turn the swivel ring 16 to drive the threaded rod 14 to rotate, and then the threaded rod 14 is threadedly connected to the inner cavity of the threaded ring 15, so that when the threaded rod 14 rotates, it can be screwed into the inner cavity of the threaded ring 15 to fix the fixing ring 12 and the sealing ring 11, or screwed out of the inner cavity of the threaded ring 15 to release the fixing ring 12 and the sealing ring 11, so that the sealing ring 11 can be disassembled.

[0033] The fixing ring 12 is fixedly connected to the middle of the inner cavity of the sealing ring 11, and cylindrical grooves are provided on the left and right sides of the sealing ring 11, and the threaded rod 14 is located in the cylindrical grooves;

[0034] The fixing ring 12 is fixedly connected to the middle of the inner cavity of the sealing ring 11, so that the fixing ring 12 can support the sealing ring 11, so that the sealing ring 11 will not be so easily deformed, and the cylindrical groove is set so that the threaded rod 14 can move inside the cylindrical groove.

[0035] The working principle and use process of the utility model are as follows: the fixed bin 1 and the connecting bin 3 are connected by the mounting bolts 2, and the insulating plate 10 is in contact with the pipeline, and the pipeline is sealed by the sealing ring 11;

[0036] When gas leaks, the gas enters the inner cavity of the connecting chamber 3, and as the amount of gas increases, it enters the inner cavity of the piston cylinder 4, pushing the piston plate 6 to move, and the piston plate 6 drives the movable reflective reminder plate 8 on the right side of the piston rod 7 to move, so that the movable reflective reminder plate 8 and the fixed reflective reminder plate 9 are staggered, and the red reflective stickers of the movable reflective reminder plate 8 and the fixed reflective reminder plate 9 leak out, thereby reminding the inspection personnel;

[0037] When the sealing ring 11 needs to be replaced, the mounting bolt 2 is tightened to separate the fixed chamber 1 and the connecting chamber 3, and then the swivel 16 is rotated. Through the engagement of the swivel 16 and the threaded ring 13, the swivel 16 is rotated upward and unscrewed from the inner cavity of the threaded ring 2 15, thereby releasing the fixation of the fixed ring 12, and then the sealing ring 11 can fall off from the inner cavity of the fixed chamber 1, and the sealing ring 11 can be replaced.

[0038] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
