Description
Technical field
The present invention relates to a kind of rubber flexible connecting pipe, especially a kind of rubber damping adapter with Large travel range compensation rate, high temperature resistant, corrosion-resistant medium.
Background technique
Rubber flexible connecting pipe is the key element of pipe-line system isolating technique, has excellent effect of vibration and noise reduction, also has the positional deviation compensated because temperature, pressure and external impact cause simultaneously.But the impact of temperature in steam, condensate line, the corrosion impact of the chemical mediators such as soda acid, greatly limit the using scope of rubber flexible connecting pipe and the performance of advantage.
The bit shift compensation scope of existing temperature resistant rubber flexibility connection pipe is 6 ~ 8mm, effectiveness in vibration suppression 5 ~ 7dB, rated pressure PN=0.6MPa, without balance requirement, purity requirements and corrosion-resistant requirement.
The major defect of existing temperature resistant rubber flexibility connection pipe is that displacement compensation amount is little, poor corrosion resistance, balance are poor, can not meet the requirement of the compensation of pipe-line system Large travel range and vibration and noise reducing.
Summary of the invention
The present invention will provide warm vibration damping adapter in one, innovated by structural type, give full play to plastics and rubber material advantage separately, rubber damping is taken over not only there is excellent effect of vibration and noise reduction, also there is Large travel range compensation rate, high temperature resistant, balance quality, cleaning and corrosion resistant feature, improve usefulness and the using scope of rubber flexible connecting pipe; By joint pipe structure optimal design, improve sealing and the balance quality of adapter; By optimization design, improve the adhesion strength of rubber and plastics, improve curability.
For achieving the above object, technological scheme of the present invention is: warm vibration damping adapter in one, comprise the rubber flexible connecting pipe of anti-DNA releaxed circular DNA, flange, cord, liner, outer layer glue, hose lining, steel ring composition, it is characterized in that: described rubber flexible connecting pipe is the vibration damping adapter with self-equilibrium characteristic, and the extended length depressed in medium remains on less than 2% of whole vibration damping connecting pipe length.
Rubber flexible connecting pipe two ends are connected with flange seal respectively, and flange is provided with anti-DNA releaxed circular DNA, and anti-DNA releaxed circular DNA is fixedly connected with rubber flexible connecting pipe, vibration damping is taken over and does not leak under vibration.
Liner is made up of polytetrafluoroethylmaterial material, and cord is that Kev draws enhancing cord, and be provided with cord in the middle of liner, the inside and outside both sides of liner are surrounded by hose lining and outer layer glue respectively, and liner embeds steel ring in two ends respectively.
The displacement compensation amount of vibration damping adapter is 18 ~ 25mm.
The invention has the beneficial effects as follows:
1. the present invention by installing vibration damping adapter in pipeline, can the mechanical vibration of effective isolated tube line structure, compensates because the pipeline temperature difference, impact such as to wave at the pipeline displacement that reason causes.Compared with existing temperature resistant rubber flexibility connection pipe, displacement compensation amount improves 200%; Effectiveness in vibration suppression improves 1 times; Balance quality reaches less than 2% of connecting pipe length; Heatproof 120 DEG C; Withstand voltage 1.6MPa; Sealability is obviously improved; Acid resistant alkali and other chemical mediators, clean water quality.
2. vibration damping adapter is provided with anti-DNA releaxed circular DNA, can improve the specific pressure of sealing surface and limit pretension distortion.
3. vibration damping adapter hose lining and outer layer glue between be provided with cord, the intensity needed for adapter is provided, by cord layout angle design can reach adapter balance.Liner is made up of polytetrafluoroethylmaterial material and is bondd with hose lining sulfuration, can keep dielectric clean, seal in end.Inside, two ends embeds steel ring, fixes cord together with flange.
Therefore, vibration damping adapter of the present invention can be applied to be had in the special pipe-line system such as temperature, corrosion, has the features such as Large travel range compensation, heatproof, corrosion-resistant, clean and excellent effect of vibration and noise reduction.

Fig. 2 is the principle schematic of adapter balance.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the invention will be further described.
As shown in Figure 1, middle temperature vibration damping adapter of the present invention, comprises anti-DNA releaxed circular DNA 1, flange 2, cord 3, liner 4, outer layer glue 5, hose lining 6, steel ring 7.
Flange 2, cord 3, liner 4, outer layer glue 5, hose lining 6, steel ring 7 form rubber flexible connecting pipe.Be provided with cord 3 in the middle of outer layer glue 5, hose lining 6, cord 3 embeds steel ring 7 in two ends respectively.Rubber flexible connecting pipe is the vibration damping adapter with self-equilibrium characteristic, and the extended length depressed in medium remains on less than 2% of whole vibration damping connecting pipe length.The displacement compensation amount of vibration damping adapter is 18 ~ 25mm.Liner 4 is made up of polytetrafluoroethylmaterial material, and cord 3 draws enhancing cord for Kev.
Rubber flexible connecting pipe two ends are connected with external flanges by flange 2, are provided with anti-DNA releaxed circular DNA 1 between flange 2 and external flanges, vibration damping is taken over and does not leak under vibration.
Anti-DNA releaxed circular DNA 1 Main Function is the specific pressure of raising sealing surface and limits pretension distortion; Cord 3 is that framework material plays humidification, can reach adapter balance (Fig. 2) by the design of cord 3 layout angle; Liner 4 is made up of polytetrafluoroethylmaterial material, and Main Function is clean and corrosion-resistant, also has the effect of heatproof.
As shown in Figure 2, be subject to the effect of three power: blind flange force T1 makes adapter extend during vibration damping adapter work, tube wall expansion counter-force T2 makes adapter shorten, and adapter pressure medium P.Wherein tube wall expansion counter-force T2 is relevant with the angle a of cord warp direction.When blind flange force T1 is greater than tube wall expansion counter-force T2, vibration damping adapter is extended, and angle a reduces, and tube wall expansion counter-force T2 is increased, until balance with blind flange force T1.The balance of warm vibration damping adapter in can being controlled by the angle a of design cord warp direction.
