Embodiment 1

[0031] like figure 1 shown.

[0032] A rotary compensator for corrosion-resistant pipelines, comprising a rotary connecting pipe 1, a sealing gland 3, a sealing seat 4 and a cone connecting pipe 7, one end of the rotary connecting pipe 1 is welded with a connecting flange 8 (this is for It is convenient for the sealing seat 4 to be conveniently set on the rotating connecting pipe 1. Only when the sealing seat 4 is set on the rotating connecting pipe 1 can the connecting flange 8 be connected to the rotating connecting pipe 1 by welding, and then through the connecting flange when in use. 8 is connected with the delivery pipeline), its other end is conical and is provided with a step surface 9, and the conical end stretches into the conical connecting pipe 7 that is also conical, and the two ends of the sealing seat 4 are respectively provided with a connecting method It is set on the rotating connecting pipe 1. When compensation is required, the sealing seat 4 and the rotatin...

Embodiment 2

[0043] like figure 2 , 3 shown.

[0044] A linear length compensation system equipped with a corrosion-resistant pipeline compensator, which includes two corrosion-resistant pipeline rotary compensators 11 and a connecting pipe 12, the center line of the corrosion-resistant pipeline rotary compensator 11 is connected to the The center line of the conveying pipeline 13 is perpendicular, and the two ends of the connecting pipe 12 pass through respective elbows (which can be connecting elbows or integral structure elbows, figure 2 What is shown is a connecting pipe (12) with a connecting elbow connected to the inlet or outlet of the corresponding corrosion-resistant pipeline rotary compensator 11. The delivery pipeline 13 is connected to the inlet or outlet of the corresponding corrosion-resistant pipeline with the rotary compensator 11 through a connecting elbow, such as figure 2 as shown, figure 2 The conveying pipelines 13 described in are parallel but not on the same ...

Embodiment 3

[0047] like Figure 4 shown.

[0048] The difference between the present embodiment and the second embodiment is that the medium delivery pipes 13 are located on the same straight line.

Abstract

The invention discloses a rotary compensator used for anti-corrosion piping and a system thereof. The rotary compensator comprises a rotary connecting pipe (1), a sealing gland (3), a sealing seat (4) and a conical connecting pipe (7). The invention is characterized in that one end of the rotary connecting pipe (1) is welded with a coupling flange (8), the other end thereof is equipped with a terrace (9) and is inserted into a taper connecting pipe (7). The sealing seat (4) is covered on the rotary connecting pipe (1), the internal surface of the sealing seat (4) is equipped with an internal convex ring (10), one side of one end surface (1001) of the internal convex ring (10) is equipped with a high pressure resistant sealing gasket (6), and the side of the other end surface (1002) of theinternal convex ring (10) is equipped with a low pressure sealing gasket (6'), the flange end of the sealing gland (3) is inserted into the sealing space of the ring surface and touches against the sealing gasket (6'), and the sealing gland (3) and the sealing seat (4), the sealing seat (4) and the taper connecting pipe (7) are all connected via the flange connection structure. The compensation system comprises at least two compensators. The rotary compensator has the advantages of long service life, good pressure resistance and large compensation rate.

Description

technical field [0001] The invention relates to a compensator for corrosive medium conveying pipelines, especially a compensator and its system used in high-pressure corrosive medium conveying pipelines in petrochemical, smelting and other industries, specifically a rotary compensator for corrosion-resistant pipelines and Manufacturing method and compensation system. Background technique [0002] As we all know, in petrochemical, special chemical, metallurgical and other industries, it is often necessary to use corrosion-resistant pipelines to transport corrosive liquids such as strong alkali and strong acid, or corrosive gases such as chlorine and ammonia, and most of these pipelines are suspended or shallow buried. Due to the influence of seasons, temperature difference between day and night and internal medium temperature, its length will change, so a pipeline compensator must be used. At present, the most commonly used compensation device is the bellows. Due to the limi...
