Abstract
The invention discloses a rubber expansion device, and relates to pipeline connection devices. The rubber expansion device comprises a rubber pipe, wherein bosses are formed at the two ends of the rubber pipe; flanges are arranged on the bosses; a plurality of connection holes are formed in the flanges; metal gaskets are fixedly arranged on the bosses; and an edge angle of each metal gasket is a chamfer. The rubber expansion device has a simple structure and is reasonable in design; because of the contact between one metal and another metal, the contact between the flanges and the rubber pipe is reduced while the operation is guaranteed, the damage to the rubber pipe is reduced, and the service life of the rubber pipe is prolonged, so that the service life of the whole rubber expansion device is prolonged.
Description
Technical field:
The present invention relates to pipeline connector spare, be specifically related to a kind of Rubber telescopic device.
Background technique:
Expansion bend also claims slip joint, expansion joint, compensator.Expansion bend is section's axial stretching within the specific limits, also can overcome in certain angle pipeline docking disalignment to and the skew that produces can greatly facilitate the dismounting that is installed on of valve pipe.Allowing in extending amount at pipeline can free-extension, just plays spacingly in case cross its maximal dilation amount, guarantees the safe operation of pipeline.Existing Rubber telescopic device, flange is stuck on rubber ring, and because flange is bolted, flange is metal material, bolt compresses after connecting, difference on metal and quality of rubber materials can cause rubber damaged for a long time, the flange displacement, affect the use of expansion bend, even cause flange to lose effect, thereby expansion bend loses effect, reduce working life.
Summary of the invention:
Technical problem to be solved by this invention is to overcome the defective of prior art, and the Rubber telescopic device that can increase the service life is provided.
Technical problem to be solved by this invention realizes by the following technical solutions.
A kind of Rubber telescopic device comprises rubber pipe, and rubber tube terminal is provided with Ka Tai, Ka Tai is provided with flange, and flange is provided with a plurality of attachment holes, it is characterized in that: be fixed with metal washer on described Ka Tai, the metal washer corner angle are made as chamfering, and the metal washer corner angle are round and smooth, and infringement reduces to rubber pipe.
The present invention is simple in structure, and is reasonable in design, and metal contacts with metal, guarantee work time, reduced contacting of flange and rubber pipe, reduced the damage of rubber pipe, extend the working life of rubber pipe, thereby extended the working life of whole Rubber telescopic device.
Description of drawings:
Fig. 1 is structural representation of the present invention;
Embodiment:
For technological means, creation characteristic that the present invention is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the present invention.
A kind of Rubber telescopic device, comprise rubber pipe 1 as shown in Figure 1, and rubber pipe 1 two ends are provided with card platform 2, and card platform 3 is provided with flange 3, and flange 3 is provided with a plurality of attachment holes 4, wherein blocks to be fixed with metal washer 5 on platform 2, and metal washer 5 corner angle are made as chamfering.
Above demonstration and described basic principle of the present invention, 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 describes in above-described embodiment and specification 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.
