Embodiment 1

[0028] refer to Figure 1 to Figure 3 , a telescopic device with self-compensating function for conveying pipelines, including a telescopic sleeve 10 and a telescopic core tube 20 with a relative movement tendency:

[0029] One end of the telescopic sleeve is the connecting end 101 of the delivery pipeline, the other end of the telescopic sleeve is the insertion end 102 of the telescopic core tube, and a first connecting flange 103 is arranged on the connecting end of the delivery pipeline of the telescopic sleeve. The above-mentioned telescopic sleeve and the first connecting flange 103 can be of an integrated structure, or a welded structure can be adopted; the preferred welding structure is: on the end face of the first connecting flange on the side connected to the telescopic sleeve An annular positioning groove is provided, and the connecting end of the transmission pipeline of the telescopic sleeve is inserted into the annular positioning groove, so that the inner and ou...

Embodiment 2

[0038] see Figure 6 and Figure 7 In this embodiment, the sealing assembly 30 includes a packing gland 301 integrally arranged at the insertion end of the telescopic core tube of the telescopic sleeve, and a packing positioning ring 302 is arranged at the inner bottom of the packing gland, and the packing gland and the telescopic core A stuffing seal cavity 303 is formed between the tubes, and an oil injection hole is arranged in the radial direction of the stuffing seal sleeve corresponding to the position of the stuffing seal cavity. The oil injection hole is equipped with a grease nozzle 304, and several A packing seal 305, between the packing seals is installed a grease retaining ring 306 that transports the lubricating grease from the grease nozzle to both ends of the entire circumferential direction; the end of the packing seal sleeve is installed with packing through fastening bolts Gland 307; other structures are the same as in Embodiment 1.

Abstract

The invention discloses a telescopic device with a self-compensation function for a conveying pipeline. The telescopic device comprises a telescopic sleeve and a telescopic core pipe which have relative movement trends, wherein one end of the telescopic sleeve is a conveying pipeline connecting end; the other end of the telescopic sleeve is a telescopic core pipe inserting end; a first connectingflange is arranged on the portion, at the conveying pipeline connecting end, of telescopic sleeve; one end of that telescopic core pipe is the other conveying pipeline connecting end; the other end ofthe telescopic core pipe is a telescopic sleeve inserting end; a second connecting flange is arranged on the portion, at the conveying pipeline connecting end, of telescopic core pipe; the outer diameter of the telescopic core pipe is smaller than the inner diameter of the telescopic sleeve; the telescopic core pipe is inserted into the telescopic sleeve; the telescopic sleeve and the telescopiccore pipe are relatively provided with telescopic spaces in the axial direction; and sealing assemblies are arranged between the telescopic sleeve and the telescopic core pipe. The telescopic device solves the problem of damage to conveying equipment or pipelines caused by overlarge stress resulting from working condition changes, equipment vibration, positive and negative pressure and other factors when pipeline conveying equipment runs.

Description

technical field [0001] The invention belongs to the technical field of pipeline conveying medium, and in particular relates to a telescopic device with self-compensating function used on conveying pipelines. Background technique [0002] At present, most pipeline transportation systems are rigidly connected by steel pipes, and some equipment uses soft connections (such as rubber pipe connections, etc.) in a certain area. cause destructive damage. Although the soft connection can absorb most of the equipment vibration, it cannot balance the axial and radial push and pull forces of the equipment, and the soft connection has certain requirements for the medium to be transported, so it is not suitable for any working conditions; in addition, in the pipeline laying process Due to installation errors, the splicing cannot be closed. [0003] For another example, some transportation pipelines erected in places with strong wind and waves, when encountering strong winds and waves, t...
