Embodiment Construction
[0011] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0012] Refer to attached figure 1 Marking instructions: 1. Outer casing, 2. Anti-drop ring, 3. Filling injection bolt, 4. Filling cylinder, 5. Fastening screw, 6. Sealing baffle, 7. Limiting stud, 8. Right limit method Lan, 9, moving tube, 10, left limit flange.
[0013] The pull rod limit type single sleeve expansion joint of the present invention comprises an outer sleeve 1, the right end of the outer sleeve 1 is internally connected with the moving tube 9 whose outer surface is plated with hard chrome, and the connection between the outer sleeve 1 and the moving tube 9 Between the interlayers is the stuffing tube 4, and the stuffing tube 4 is injected with a flexible graphite ring. The flexible graphite ring is characterized by high strength, small friction coefficient, no aging, good effect, and convenient maintenance. The right port of the outer casing...

The invention discloses a pull rod limiting type single sleeve expansion joint. According to the technical scheme, the pull rod limiting type single sleeve expansion joint comprises an outer sleeve, a movable pipe and a filler barrel, wherein the movable pipe is connected with the interior of the outer sleeve, the filler barrel is located in an interlayer between the outer sleeve and the movable pipe, a connection port of the outer sleeve and the movable pipe is provided with a sealing baffle, a fastening screw is arranged on the periphery of the sealing baffle, the overlapping position of the outer sleeve and the filler barrel is provided with a filler injection bolt, a left limiting flange is arranged at the right end of the outer sleeve, an anti-falling ring is arranged at the left end of the movable pipe, a right limiting flange is arranged at the right end of the movable pipe, and the left limiting flange is connected with the right limiting flange through a limiting bolt. The pull rod limiting type single sleeve expansion joint has the advantages that the double limiting flanges and the limiting bolt are used for solving the problem that under the action of heat-expansion and cold-contraction of the expansion joint, the movable pipe is prone to leakage due to internal pressure thrust; due to an injection mode, when the sealing effect is weakened, sealing filler is convenient to inject again; operation is easy, the structure is compact, and service life is long.
Description
technical field [0001] The invention relates to the field of application of telescopic joints, in particular to a pull rod-limited single-type sleeve telescopic joint. Background technique [0002] Sleeve expansion joints are often used in water pipes, gas pipes and low-pressure steam pipes because of their low price, long service life, pressure resistance, corrosion resistance, and high temperature resistance. The thermal expansion and contraction of these pipes produces a relatively large stress on the pipe wall and a large amount of compensation for the push-pull force, and the strong thermal deformation is likely to cause leakage of the moving pipe in the expansion joint. Contents of the invention [0003] The object of the present invention is to provide a single-type sleeve telescopic joint limited by a tie rod, which effectively solves the problem of leakage of the moving tube under the action of thermal expansion and contraction of the telescopic joint. At the sam...
