Abstract
The invention discloses a rubber expansion device with high elasticity. The rubber expansion device comprises an elastic rubber pipe body, clamping steps are arranged on the outer walls of the two ends of the elastic rubber pipe body, loose metal flanges are connected to the clamping steps, and the elastic rubber pipe body is formed by a rubber sphere formed by an inner rubber layer and an outer rubber layer in a composite mode. The rubber expansion device with the high elasticity has the advantages of being resistant to high pressure, good in elasticity, large in displacement, good in vibration absorption and noise reduction effect, convenient to mount and the like. The rubber expansion device can be widely used in pipe systems of water supplying and drainage, water circulation, heat ventilation, air-conditioning, fire fighting, paper making, pharmacy, petrochemical engineering, ships, water pumps, compressors, fans and the like.
Description
Technical field
The present invention relates to valve technology field, be specifically related to the Rubber telescopic device that a kind of elasticity is strong.
Background technique
Expansion bend also claims slip joint, expansion joint, compensator.Expansion bend within the specific limits can axial stretching, also can in certain angle, overcome pipeline docking disalignment to and the skew that produces, can greatly facilitate the installation and removal of valve pipe, at pipeline, allowing in extending amount can free-extension, once cross its maximal dilation amount, just play spacingly, guarantee the safe operation of pipeline.Be mainly and ensure pipe safety operation, there is following effect: compensation extraction duct is axial, horizontal, angle thermal distortion; Absorption equipment vibration, reduces the impact of vibration equipment on pipeline; Absorb earthquake, the amount of deformation of earth subsidence to pipeline.
Summary of the invention
It is a kind of simple in structure that technical problem to be solved by this invention is to provide, the strong Rubber telescopic device of elasticity that practicability is good.
Technical problem to be solved by this invention realizes by the following technical solutions:
The Rubber telescopic device that elasticity is strong, comprises elastic caoutchouc body, and the outer wall at described elastic caoutchouc body two ends is provided with Ka Tai, is connected with pine cover metal flange on described Ka Tai, and described elastic caoutchouc body consists of inner glue layer and the compound rubber ball body of outer glue-line.
The thickness of described inner glue layer is 1/2 of outer bondline thickness.
The invention has the beneficial effects as follows: the present invention has high pressure resistant, good springiness, displacement amount is large, absorb vibration and reduce the advantages such as noise result is good, easy for installation, can be widely used in the pipe-line systems such as water supply and drainage, circulating water, Heating,Ventilating and Air Conditioning (HVAC), fire-fighting, papermaking, pharmacy, petrochemical industry boats and ships water pump, compressor, blower fan.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
For technological means, creation characteristic that the present invention is realized, reach object and effect is easy to understand, below in conjunction with concrete diagram, further set forth the present invention.
As shown in Figure 1, the Rubber telescopic device that a kind of elasticity is strong, comprise elastic caoutchouc body 1, the outer wall at elastic caoutchouc body 1 two ends is provided with card platform 2, on card platform 2, be connected with pine cover metal flange 3, elastic caoutchouc body 1 consists of inner glue layer 102 and the compound rubber ball body of outer glue-line 103, and the thickness of inner glue layer 102 is 1/2 of outer glue-line 103 thickness.
More than show and described basic principle of the present invention and major character and advantage of the present invention.The technician of the industry should understand; the present invention is not restricted to the described embodiments; that in above-described embodiment and specification, describes just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
