In order to solve the technical problem, the utility model adopts the following technical scheme:
the utility model provides a telescopic joint for pipeline, includes flexible outer tube, flexible interior sleeve pipe, flexible outer tube inner wall hug closely on flexible interior sleeve pipe outer wall, flexible outer tube and flexible interior sleeve pipe can relative slip, flexible outer tube on be provided with first flange, first flange on be provided with first connecting bolt, flexible interior sleeve pipe on be provided with second flange, flexible outer tube on be provided with first guide flange, first guide flange on be provided with guide bolt.
The telescopic inner sleeve is provided with a limiting flange, and the outer end of the guide bolt is provided with a limiting bolt.
The guide bolts are arranged in two numbers and are respectively and symmetrically arranged on the telescopic outer sleeve.
The telescopic outer sleeve is provided with a sealing ring and a sealing pressing piece, the sealing pressing piece and the sealing ring are arranged on a sealing block, and the sealing block is provided with a bolt hole.
And a compression bolt is arranged outside the sealing block and is connected to the guide bolt through threads.
And an elastic sealing gasket is arranged at the joint of the first connecting flange and the second connecting flange.
Compared with the prior art, the utility model discloses one of following beneficial effect has:
1. the utility model discloses stop device adopts flange and bolt to carry on spacingly, and the pulling force that can bear is great, uses reliably.
2. The utility model discloses the sealing washer sets up the convenient change, and at the in-process that expansion joint used, seal structure leakproofness is good.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
In the figure: 1-a first guide flange, 2-a sealing pressing sheet, 3-a sealing ring, 4-a pressing bolt, 5-a guide bolt, 6-a limiting bolt, 7-a telescopic inner sleeve, 8-a second connecting flange, 9-a telescopic outer sleeve, 10-a first connecting bolt, 11-a limiting flange, 12-a sealing block and 13-a first connecting flange.
Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Example 1
The utility model provides a telescopic joint for pipeline, includes flexible outer tube 9, flexible interior sleeve pipe 7, flexible outer tube 9 inner wall hug closely on flexible interior sleeve pipe 7 outer wall, flexible outer tube 9 and flexible interior sleeve pipe 7 can the relative slip, flexible outer tube 9 on be provided with first flange 13, first flange 13 on be provided with first connecting bolt 10, flexible interior sleeve pipe 7 on be provided with second flange 8, flexible outer tube 9 on be provided with first flange 1, first flange 1 on be provided with guide bolt 5.
The telescopic outer sleeve 9 can slide on the outer wall of the telescopic inner sleeve 7, so that the pipeline connection is extended, the guide bolt 5 can guide the telescopic outer sleeve 9 to slide on the telescopic inner sleeve 7, and the pipeline leakage caused by the fact that the telescopic outer sleeve 9 deviates from an axial path due to overlarge pressure in the pipeline is avoided.
Example 2
On the basis of embodiment 1, the telescopic inner sleeve 7 is provided with a limiting flange 11, and the outer end of the guide bolt 5 is provided with a limiting bolt 6. Can be through the flexible length of the position control expansion joint of adjusting spacing bolt 6, the length of expansion joint can effectively be injectd to the spacing flange 11 of setting, possess sufficient intensity simultaneously and avoid the expansion joint that leads to because the impact of pipeline internal pressure is pulled bad.
Example 3
On the basis of the embodiment 1-2, two guide bolts 5 are arranged and are respectively and symmetrically arranged on the telescopic outer sleeve 9. The guide bolt 5 is provided in two pieces to better protect the expansion joint from damage.
Example 4
On the basis of embodiments 1-3, the telescopic outer sleeve 9 is provided with a sealing ring 3 and a sealing pressing sheet 2, the sealing pressing sheet 2 and the sealing ring 3 are arranged on a sealing block 12, and the sealing block 12 is provided with a bolt hole. The sealing ring 3 and the sealing pressing piece 2 can avoid pipeline leakage, and the sealing ring 3 and the sealing pressing piece 2 are arranged in the sealing block 12, so that the sealing ring 3 and the sealing pressing piece 2 are convenient to replace.
Example 5
On the basis of the embodiments 1-4, the outside of the sealing block 12 is provided with the compression bolt 4, and the compression bolt 4 is connected to the guide bolt 5 through threads. The hold-down bolt 4 can better compress the seal ring 3 and the seal pressing sheet 2, and the sealing performance of the pipeline is improved.
