Description

Technical Field

[0001] The utility model belongs to the technical field of pipeline regulation, and in particular relates to a pipeline regulating device. Background Art

[0002] In the high-voltage switch industry, gas pipes are commonly and widely used. For example, different gas chambers that share a SF6 density controller are connected in series with stainless steel gas pipes with a diameter of 10 mm. The lower lead of the SF6 density controller needs to be connected through a gas pipe. The length of the gas pipe varies greatly depending on the high-voltage switch. The general length is between 1 meter and 2 meters, and the longest can reach 3 meters or even longer. However, due to the large difference in the positions of the two ends of the gas pipe, the installation parts at both ends of the gas pipe cannot be strictly aligned during installation.

[0003] Since the installation position cannot be aligned, the upper installation end and the lower installation end of the pipeline are misaligned during installation. If the pipeline is to be assembled in place, the pipeline must be forcibly moved. Although the upper installation end and the lower installation end can be assembled after the pipeline is forcibly moved, the pipeline is under stress for a long time, which is seriously detrimental to the welding parts of the pipeline. Long-term operation may cause cracks in the pipeline itself and cracks in the welding parts, which will eventually lead to air leakage.

[0004] At present, in order to solve the above problems, the existing technology sets a U-shaped bend on the air pipe and adjusts the U-shaped bend to achieve the adjustment of the installation end; however, this adjustment method is still another operation method of turning the pipeline, and actually the adjustment is achieved by turning the pipeline.

[0005] Based on the above problems, the utility model proposes a pipeline regulating device. Utility Model Content

[0006] The utility model aims to provide a pipeline adjustment device, which can adjust the direction and length of the pipeline by adjusting the adjustment member and the flexible tube, so as to avoid the pipeline being moved during the pipeline adjustment process, thereby causing problems such as complete deformation of the pipeline, stress concentration, cracks in the welding parts, etc.

[0015] Furthermore, a plurality of opposite holes are arranged around the upper fixing plate and the lower fixing plate, and the adjusting member passes through the opposite holes to connect the upper fixing plate and the lower fixing plate.

[0026] The following will be combined with the accompanying drawings to describe the preferred embodiments of the present invention in detail, so as to more clearly understand the purpose, characteristics and advantages of the present invention. It should be understood that the embodiments shown in the accompanying drawings are not intended to limit the scope of the present invention, but are only intended to illustrate the essential spirit of the technical solution of the present invention.

[0027] like Figure 3 As shown, the prior art achieves adjustment of the mounting end by setting a U-shaped bend A on the air pipe and adjusting the U-shaped bend; however, this adjustment method is still another operation method of turning the pipeline, and actually the adjustment is still achieved by turning the pipeline.

[0029] The flexible tube 3 is arranged between the upper fixing plate 1 and the lower fixing plate 2, and the flexible tube 3 is sleeved outside the end to be connected of the first pipeline and the end to be connected of the second pipeline. The upper fixing plate 1 and the lower fixing plate 2 are provided with opposite through holes at their central positions, the through hole of the upper fixing plate 1 is connected to the first pipeline, and the through hole of the lower fixing plate 2 is connected to the second pipeline; the first pipeline and the second pipeline are both welded to the upper fixing plate 1 and the lower fixing plate 2 by solder 9, and the upper fixing plate 1 and the lower fixing plate 2 are connected by the flexible tube 3.

[0030] Specifically, the flexible tube 3 includes an inner flexible tube 301 and an outer flexible tube 302. The inner flexible tube 301 is arranged between the upper fixed plate 1 and the lower fixed plate 2. The inner flexible tube 301 is sleeved on the outside of the end to be connected of the first pipeline and the end to be connected of the second pipeline. The outer flexible tube 302 is arranged between the upper fixed plate 1 and the lower fixed plate 2. The outer flexible tube 302 and the inner flexible tube 301 are gap-ringed, and the outer flexible tube 302 is arranged between the peripheries of the relative through holes.

[0031] As a preferred embodiment, the inner flexible tube 301 and the outer flexible tube 302 are preferably metal corrugated tubes. The inner flexible tube 301 and the outer flexible tube 302 may also be other elastic tubes.

[0032] As a preferred embodiment, a spring is also sleeved on the outer circumference of the outer flexible tube 302, which can further protect the outer flexible tube. The inner flexible tube and the outer flexible tube can be tilted or stretched or shortened to the direction to be adjusted, so as to achieve the purpose of adjusting the pipeline.

[0033] In the present application, pipelines are welded on the upper fixed plate and the lower fixed plate, and the gas in the pipeline circulates through the inner bellows, which is mainly responsible for sealing the gas; the two ends of the inner flexible tube are respectively connected to the through holes of the upper fixed plate and the lower fixed plate, and the inner flexible tube is welded to the upper fixed plate and the lower fixed plate by a solder welding annular seam method; the outer flexible tube is welded to the outer periphery of the through holes of the upper fixed plate and the lower fixed plate by a solder welding annular seam method, and the outer flexible tube also has a sealing function.
