Abstract
A novel corrugated compensator comprises a corrugated pipe, a support and a lining. The corrugated pipe is arranged on the support, and a flow guide cylinder is arranged in the corrugated pipe and arranged on the support through a flange. The outer diameter of the flow guide cylinder is slightly smaller than the inner diameter of the corrugated pipe, and the height of the flow guide cylinder is slightly smaller than that of the corrugated pipe. The lining is arranged between the flow guide cylinder and the corrugated pipe and attached to the corrugated pipe. The novel pipeline corrugated compensator can support lining material of a corrugated pipe with lining material in a large-aperture negative-pressure pipeline so that the lining material can be effectively protected in a negative pressure environment and it can be avoided that because the negative pressure is too large, the flexible lining material is disengaged from a threaded pipe, then, the lining material occupies the area of a channel, and internal resistance of the channel is increased. The novel corrugated compensator can make air flow in the pipeline smooth, stop turbulence from being formed, and the service life of the lining material is effectively prolonged.
Description
Technical field
The utility model belongs to chemical industry, metallurgical technology field, is specifically related to a kind of novel pipeline FlexbleJoint.
Background technique
In Chemical Manufacture, for the problem of stress concentration that relieving system process pipeline expands with heat and contract with cold and causes, the stress that often can use FlexbleJoint to produce process pipeline discharges, to guarantee the stable operation of system process pipeline.Existing FlexbleJoint is normally used is with the compensator of guide shell and the compensator of inside lining anti-corrosive material.According to pipeline, the different and interior medium difference of pipe, can adopt different compensators to be connected with pipeline conventionally.The compensator of inside lining anti-corrosive material is generally used for to carry to be had on the pipeline of Korrosionsmedium.Because compensator inner lining material and the rigidity bellows material property of inside lining anti-corrosive material are different, and in order not affect the normal use of compensator, can not adhesion between inner lining material and bellows.Different according to carried medium, in pipeline, have two kinds of pressure condition, when carrying liquid or slurry, most of pipeline is under barotropic state, and the inside liner of FlexbleJoint can be close to bellows, well uses; And in heavy caliber gas transmission pipeline, most of pipeline is in negative pressure state, because the inside liner of FlexbleJoint is directly connected with bellows, very easily the breakage due to bellows causes inside liner and rigidity bellows come off and are inhaled into pipeline, results in blockage.
Model utility content
Technical problem to be solved in the utility model is for shortcoming of the prior art, to provide a kind of inner lining material of pipeline FlexbleJoint that makes under subnormal ambient, to be effectively protected, to avoid to make because negative pressure is excessive flexible lining material and threaded pipe disengaging to cause inner lining material to occupy the novel pipeline FlexbleJoint of aisle spare, increase channel interior resistance.
For solving technical problem of the present utility model, adopt following technological scheme:
A kind of New type corrugated compensator, comprise bellows, support and liner, described bellows is located on support, in described bellows, guide shell is set, described guide shell arranges on support by flange, the external diameter of described guide shell is slightly less than the internal diameter of bellows, is highly slightly less than the height of bellows, between described guide shell and bellows, liner is set, and described liner is mounted on bellows.
The material of described guide shell is the corrosion-resistant material of rigidity.
The utility model provides a kind of New type corrugated compensator; this equipment can be to there being the inner lining material of the bellows of inner lining material to support in heavy caliber negative-pressure pipeline; make inner lining material under subnormal ambient, be effectively protected, avoid to make because negative pressure is excessive flexible lining material and threaded pipe to depart from and cause inner lining material to occupy aisle spare, increase channel interior resistance; make pipeline internal gas flow unobstructed; stop turbulent flow to form, effectively extended inner lining material working life.
accompanying drawing explanation:
Fig. 1 is the utility model structural representation.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in Figure 1, a kind of New type corrugated compensator, comprises bellows 1, support 4 and liner 2, and bellows 1 is arranged on support 4, and at the interior installation guide shell 3 of bellows 1, guide shell 3 is fixed on support 4 with flange at feedstock direction.Wherein the external diameter of guide shell 3 is slightly less than the internal diameter of bellows 1, is highly slightly less than the height of bellows 1, between guide shell 3 and bellows 1, liner 2 is installed, and liner 2 is mounted on bellows 1.The material of guide shell 3 is the corrosion-resistant material of rigidity.
The utility model guide shell 3 can be to there being the liner 2 of the bellows 1 of liner 2 to support in heavy caliber negative-pressure pipeline; make liner 2 under subnormal ambient, be effectively protected, avoid to make because negative pressure is excessive flexible lining 2 and bellows 1 to depart from and cause liner 2 to occupy aisle spare, increase channel interior resistance; make pipeline internal gas flow unobstructed; stop turbulent flow to form, effectively extended the working life of liner 2.
