Abstract
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
The present invention relates to slip joint application, relate in particular to tension rod locating type single entry sleeve slip joint.
Background technique
Sleeve slip joint is because of its cheap price, and in longer working life, resistance to compression, the feature such as corrosion-resistant, high temperature resistant are usually used in waterpipe, gas pipe line and low pressure steam pipeline.These pipelines expand with heat and contract with cold and produce the stress of tube wall and push-pull effort compensation rate and require greatlyr, and strong thermal distortion easily makes the movable pipe in slip joint leak.
Summary of the invention
The object of this invention is to provide a kind of tension rod locating type single entry sleeve slip joint, efficiently solve under the slip joint effect of being expanded with heat and contract with cold, there is the problem of leaking in movable pipe.Filling type design simultaneously makes to supplement stuffing box packing, and operation is simple.
To achieve these goals, technological scheme of the present invention is achieved in that tension rod locating type single entry sleeve slip joint, it comprises outer sleeve 1, inside be connected to the movable pipe 9 of described outer sleeve 1, and be positioned at described outer sleeve 1, filling tube 4 in interlayer between movable pipe 9, described outer sleeve 1 is provided with sealing baffle 6 with the port that described movable pipe 9 is connected, the outer fastening screw 5 that is arranged with of described sealing baffle 6, described outer sleeve 1 is also provided with filler with described filling tube 4 overlappings and injects bolt 3, the right-hand member of described outer sleeve 1 is provided with left limit flange 10, described movable pipe 9 left ends are provided with anti-decylization 2, right-hand member is provided with right limit flange 8, described left limit flange 10, between right limit flange 8, connect by spacing double-screw bolt 7.
Further, described filler injects bolt 3 and has two, is symmetrically distributed in the both sides of described outer sleeve 1.
Further, described filling tube 4 injects Expanded graphite ring.
Further, described tension rod locating type single entry sleeve slip joint is that metallic material is made.
Further, the slidingsurface durionise of described movable pipe 9.
The present invention has following beneficial effect: the use of two spacing flanges and spacing double-screw bolt, efficiently solves under the slip joint effect of being expanded with heat and contract with cold the problem that movable pipe is easily leaked by interior pressure thrust.The design of filling type conveniently, in the time that sealing effect weakens, is inserted one deck or two-layer stuffing box packing again, simple to operate, compact structure, and long service life, fatigue life and pipeline are suitable, and engineering cost is low.And slidingsurface is through durionise processing, smoothness is high, hardness is high, antirust, corrosion-resistant, resistance to wear, high temperature resistant.
Brief description of the drawings
Fig. 1 is structural representation of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the present invention will be further described in detail.
With reference to accompanying drawing 1 description of symbols: 1, outer sleeve, 2, anti-decylization, 3, filler injects bolt, 4, filling tube, 5, fastening screw, 6, sealing baffle, 7, spacing double-screw bolt, 8, right limit flange, 9, movable pipe, 10, left limit flange.
Tension rod locating type single entry sleeve slip joint of the present invention, it comprises outer sleeve 1, in the right-hand member of described outer sleeve 1, connect the described movable pipe 9 of outer surface durionise, between described outer sleeve 1 and the interlayer of movable pipe 9, it is described filling tube 4, described filling tube 4 injects Expanded graphite ring, and the feature of Expanded graphite ring is not that intensity is large, friction factor is little, aging, effective, easy to maintenance etc.The right output port place of described outer sleeve 1 is provided with sealing baffle 6, described sealing baffle 6 is used for stopping that extraneous foreign material enter in slip joint, the stuffing box packing that also can prevent described filling tube 4 comes off, described sealing baffle 6 is provided with described fastening screw 5, described outer sleeve 1 is also provided with filler with described filling tube 4 overlappings and injects bolt 3, after the sealability of slip joint weakens, can again inject the entrance injection stuffing box packing of bolt 3 from described filler.Described filler injects bolt 3 and has two, be symmetrically distributed in the both sides of described outer sleeve 1, the right-hand member of described outer sleeve 1 is provided with left limit flange 10, and described movable pipe 9 right-hand members are provided with right limit flange 8, and described left limit flange 10, right limit flange 8 connect by spacing double-screw bolt 7.That described left and right spacing flange, spacing double-screw bolt 7 play in the time that movable pipe 9 is expanded with heat and contract with cold effect to-and-fro motion is spacing, Drop-proof, anti-leak effect.Described tension rod locating type single entry sleeve slip joint is that metallic material is made, long service life, and overall cost is cheap.
Finally explanation is, above embodiment is only unrestricted in order to technological scheme of the present invention to be described, other amendments that those of ordinary skill in the art make technological scheme of the present invention or be equal to replacement, only otherwise depart from the spirit and scope of technical solution of the present invention, all should be encompassed in the middle of claim scope of the present invention.
