Description
Technical field
The utility model is related to a kind of expansion joint of petrochemical industry, and especially one kind contains solid particle suitable for medium
And top-down vertical pipe is flowed to, and the erosion resistant of expansion joint can be increased and ensure the stable external pressure axial direction of velocity of medium
Type expansion joint, the outer pressure axial type expansion joint of specifically a kind of anti-throttling of erosion resistant.
Background technology
At present, outer pressure axial type expansion joint is because it absorbs larger axial displacement and is obtaining widely should in petrochemical industry
With.But, the place of taking root of the inside lining sleeve for the outer pressure axial type expansion joint that traditional flange is connected is easily by Jie containing solid particle
Matter is worn away, and it is not used normally.If, using the inside lining sleeve of heavy wall, circulation can be made again to prevent too fast abrasion
Area reduces and causes velocity of medium unstable, influences the using effect of expansion joint.Accordingly, it would be desirable to a kind of both erosion resistants are designed,
Throttling can be prevented again, while ensureing the expansion joint of medium speed stabilizing flowing, better met and contained solid particle in petrochemical industry medium
And flow to the use requirement of top-down vertical pipe.
Utility model content
The purpose of this utility model is that there is provided a kind of outer pressure axial type of the anti-throttling of erosion resistant in view of the shortcomings of the prior art
Expansion joint, on the premise of can not reducing ensuring circulation area, it is to avoid inside lining sleeve is worn and torn by particle in medium, is improved swollen
Swollen section erosion resistant energy, meanwhile, can also it avoid medium from throttling, it is ensured that flow speed stability, so as to better meet petrochemical industry
Use demand.
The technical solution of the utility model is：
A kind of outer pressure axial type expansion joint of the anti-throttling of erosion resistant, including upstream adapter, downstream adapter and outer tube, it is described on
Trip adapter is cylindrical shape, and its left end connection upstream flange, right-hand member is hanging；The downstream adapter includes raising adapter and reduced pipe；
Described to raise adapter for cylindrical shape, diameter is taken over more than the upstream, and its right-hand member connects downstream flange by the reduced pipe, its
Left end is vacantly sleeved on the upstream adapter right-hand member.
The outer tube sleeve takes over and raised the outside of adapter mounted in the upstream, and is raised described between adapter and outer tube
Provided with bellows；The left end of the outer tube is connected by the first pressure-bearing ring flat-plate with upstream adapter, and right-hand member passes through the 3rd pressure-bearing
Ring flat-plate is connected with the right-hand member of the bellows；The left end of the bellows passes through the second pressure-bearing ring flat-plate and the left side for raising adapter
End is connected.
Further, the longitudinal section of the reduced pipe is taper type, and its small end is connected with the downstream flange, its big end and
Adapter is raised to be connected.
Further, the internal diameter of the upstream flange be micro- toroidal, bell-mouthed big end outwardly, small end end and institute
Upstream adapter is stated to be connected.
The beneficial effects of the utility model：
The utility model is reasonable in design, simple in construction, not only effectively increases the wearability of expansion joint, and, it can be ensured that
Circulation area is not reduced, it is ensured that the steady flow of medium, can better meet the use demand of petrochemical industry.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.

Embodiment
The utility model is further described with reference to the accompanying drawings and examples.
Nominal purpose all for ease of description such as " left side " " right side " involved by herein, not to the limit of the utility model structure
It is fixed, illustrate hereby.
As shown in Figure 1.
A kind of outer pressure axial type expansion joint of the anti-throttling of erosion resistant, including upstream adapter 3, downstream adapter and outer tube 5.It is described
Upstream adapter 3 is cylindrical shape, and its left end is connected with upstream flange 1, and right-hand member is hanging.The downstream adapter includes raising adapter 6
With reduced pipe 9.Wherein, it is described to raise adapter 6 for cylinder barrel shaped, and diameter is taken over more than the upstream.The reduced pipe 9 it is vertical
Section is taper type, and small end is connected with downstream flange 10, and big end is connected with the right-hand member for raising adapter 6.It is preferred that, it is described different
The taper of footpath pipe can be 1:1.5 or so, it is both ensured the continuity of internal structure, ensure that the steady of media flow
It is qualitative, it is to avoid the generation of throttling.The left end for raising adapter 6 is hanging, and the right-hand member of the upstream adapter 3 is vacantly sleeved on
In it.The outer tube 5 is set in the upstream adapter 3 and raises the outside of adapter 6, and is connect in the outer tube 5 and described raise
Bellows 7 is additionally provided with the middle of pipe 6.The left end of the outer tube 5 is connected by the first pressure-bearing ring flat-plate 2 with the upstream adapter 3, right-hand member
It is connected by the 3rd pressure-bearing ring flat-plate 8 with the right-hand member of the bellows 7.The left end of the bellows 7 by the second pressure-bearing ring flat-plate 4 with
The left end for raising adapter 6 is connected, and upstream adapter 3, downstream adapter and outer tube 5 is collectively formed Jie that bellows bears external pressure
Matter flow channel, and the bellows 7 is absorbed the axial displacement from the pipeline generation that is connected with expansion joint.Further
, the internal diameter of the upstream flange 1 is micro- toroidal, bell-mouthed big end outwardly, small end end and the phase of upstream adapter 3
