Embodiment 1

[0027] like figure 1 , 2 shown.

[0028] A safe explosion-proof high-pressure resistant self-sealing rotary compensator, which includes a different-diameter outer tube 1 and an inner tube 2. One end of the different-diameter outer tube 1 is connected to the delivery pipeline, and the other end is sleeved on the inner tube 2. The inner tube 1 One end is inserted into the outer pipe of different diameter 1, and the other end is connected with another section of delivery pipeline, such as figure 2 shown. One end of the inner tube 2 is positioned in the outer tube 2 with a different diameter, and at least one end face sealing cavity with a seal 5 is formed between the inner tube 2 and the outer tube 1 with a different diameter. The end face of the annular outer boss 3, the end face of the annular inner boss 4 on the inner tube 1 of different diameter adjacent to the annular outer boss 3, the outer surface of the inner tube 1 and the inner surface of the outer tube 1 of the dif...

Embodiment 2

[0033] like image 3 shown.

[0034] The difference between this embodiment and Embodiment 1 is that the flange for positioning the annular sealing ring 6 is positioned by an elastic positioning device composed of a spring and a guide rod. The spring is set on the guide rod, and the guide rod is installed on the end face of the flange. superior. like image 3 shown.

Embodiment 3

[0036] like Figure 4 shown.

[0037]A safe explosion-proof self-sealing rotary compensator, which is suitable for compensating pipelines with low pressure, it includes a different-diameter outer tube 1 and an inner tube 2, and one end of the inner tube 2 is positioned in the different-diameter outer tube 2. Between the inner tube 2 and the outer tube 1 with a different diameter is formed at least one annular sealing cavity equipped with a ring sealing ring 6, and at least one explosion-proof structure is provided between the inner tube 2 and the outer tube 1 with a different diameter. The explosion-proof structure is composed of an annular outer shoulder 9 on the outer surface of the inner tube 1 and an annular inner shoulder 10 on the inner surface of the outer tube 1 with different diameters. The explosion-proof structure of this embodiment must be located between the ring surface sealing ring 6 and the end of the special-shaped outer tube 1 with the insertion hole. the p...

Abstract

The invention relates to a safety anti-explosion self-sealing rotary compensator. The compensator comprises a reducing outer pipe (1) and an inner pipe (2), wherein one end of the inner pipe (2) is positioned in the reducing outer pipe (1); at least one end face sealing cavity provided with a sealing piece (5) is formed between the inner pipe (2) and the reducing outer pipe (1); and the sealing cavity consists of the end face of an annular outer boss (3) on the inner pipe (2), the end face of an annular outer boss (4) on the reducing outer pipe (1), which is adjacent to the annular outer boss(3), the external surface of the inner pipe (1) and the internal surface of the reducing outer pipe (1). The compensator is characterized in that: at least one anti-explosion structure is arranged between the inner pipe (2) and the reducing outer pipe (1) and is formed by matching an annular outer convex shoulder (9) on the external surface of the inner pipe (1) with an annular inner convex shoulder (10) on the internal surface of the reducing outer pipe (1). The safety of the rotary compensator is radically improved, and the application range of the rotary compensator is further expanded.

Description

technical field [0001] The invention relates to a pipeline length compensation device, especially an explosion-proof rotary compensator that can improve the safety level and prevent the medium from leaking due to the separation of the inner tube and the outer tube of the rotary compensator when an explosion occurs. Explosion-proof and self-sealing rotary compensator. Background technique [0002] At present, as a new pipeline length compensation device, the rotary compensator has been widely used in petrochemical, metallurgy, heating and other industries, fully demonstrating its advantages of large compensation length, simple structure, convenient installation and use, and low cost. The existing structure of the rotary compensator has only one end face sealing structure, which can fully meet the requirements of use under normal circumstances, but from the perspective of safety, especially in some high-temperature and high-pressure pipelines and pipelines with frequent te...
