Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Example (b): the utility model provides a shock attenuation sealing tube connects, as shown in figure 1, includes that flexible body 1 and cover establish the sleeve pipe 2 at flexible body 1 both ends, and in actual installation, operating personnel only need locate two sections ports of waiting to connect the body with flexible body 1 cover to realize fixing through sleeve pipe 2 can.

Because circulation medium can produce a large amount of fluctuations and vibrate when passing through pipe connection head in the pipeline, flexible pipe has included to inhale shake tub 4 and has set up in inhaling the fixed pipe 5 at shake tub 4 both ends among this pipe connection head, utilizes fixed pipe 5 to cup joint with treating the connecting tube mouth, and the shake of flexible pipe middle part is managed 4 and then can be realized the buffering and inhale the shake effect.

Be equipped with elasticity cavity 3 in the pipe wall of flexible pipe body 1, wherein be located and be equipped with shock-absorbing assembly in the elasticity cavity 3 of fixed pipe 5, shock-absorbing assembly includes a plurality of 3 chamber wall fixed connection's of elasticity cavity function blocks 7 of moving away to avoid possible earthquakes, shock-absorbing function blocks 7 are the wedge, and be located the 3 both sides chamber wall of elasticity cavity function blocks 7 of moving away to avoid possible earthquakes of moving away to the contrary distribution mutually, when fixed pipe 5 is in to the pipe orifice cup joint fixed time, operating personnel application of force makes fixed pipe 5 compress, the wedge shock-absorbing block that 3 chamber walls of elasticity cavity set up offsets after the extrusion, can ensure stable sealed conflict. And be equipped with restriction ear piece 10 in the outside of fixed pipe 5, be equipped with in the sleeve pipe 2 with restriction ear piece 10 complex lasso 11, can ensure sleeve pipe 2 and wait to cup joint the abundant stable fixed between the mouth of pipe, reduce the great relative sliding displacement that appears between sleeve pipe 2 and the fixed pipe 5.

The inner wall of the shock absorbing pipe 4 positioned between the fixed pipes 5 is in an inner arc shape, the shock absorbing pipe 4 contracts towards the inside of the pipe, meanwhile, an energy absorbing block 8 is arranged in the cavity of the elastic cavity 3 positioned on the shock absorbing pipe 4, the energy absorbing block 8 is in a hemispherical shape, and as the shock absorbing pipe 4 contracts towards the inside of the pipe, the hemispherical energy absorbing block 8 on the wall of the elastic cavity 3 close to one side in the pipe is in an extrusion contraction state, so that the shock absorbing pipe has expansion potential energy in an outward expansion recovery state; meanwhile, the hemispherical energy absorption block 8 on the other side cavity wall of the elastic cavity 3 is in an open state and has contraction potential energy in a contraction recovery state.

When the flowing medium in the pipe passes through the shock absorbing pipe 4, the flowing medium contacts with the inner wall of the shock absorbing pipe 4 firstly, so that the shock absorbing pipe 4 which contracts in the pipe is extruded and deformed outwards, the energy absorbing block 8 in the elastic cavity 3 synchronously acts along with the stress deformation of the shock absorbing pipe 4, the energy absorbing block 8 close to one side in the pipe is in an extruded shape under the normal state of the energy absorbing block, once the energy absorbing block is extruded by the flowing medium in the pipe, the energy absorbing block has the tendency of getting rid of the extrusion and contraction to restore to a hemispherical state, the impact force of the flowing medium is absorbed along with the deformation of the shock absorbing pipe 4 and is converted into the expansion energy of the hemispherical energy absorbing block 8, and in order to quickly and effectively realize the shock absorbing effect of a first shock absorbing line, the sphere diameter of the energy absorbing block 8 on the wall of the elastic cavity 3 close to one side in the pipe is larger than that of the energy absorbing block 8 on the wall of the other side, the external force of the medium flowing in the pipe under the first action can be eliminated effectively and immediately by the energy absorption block 8 with the larger ball diameter.

When the impact force of the circulating medium in the tube continuously applies pressure to the shock-absorbing tube 4, so that the energy-absorbing block 8 close to one side in the tube has the tendency of expanding and expanding at the same time, the requirement that the energy-absorbing block 8 with the smaller spherical diameter on the other side on the inner wall of the elastic cavity 3 is extruded is met, because the energy-absorbing block 8 on the side wall of one side in the tube 3 is kept expanding and expanding in a normal state, the energy-absorbing block shrinks and recovers to the hemispherical shape in the extrusion process, the impact potential energy of the transmitted circulating medium is absorbed immediately, and the outer wall of the shock-absorbing tube 4 which shrinks originally in the tube is also expanded outwards under the force, the requirement that the circulating medium in the tube continuously applies force to the shock-absorbing tube 4 is met, the side wall on the outer side of the shock-absorbing tube 4 continuously expands outwards, the elastic cavity 3 is far away from the energy-absorbing block 8 on the inner cavity wall of the tube and shrinks and extrudes, and when the flowing medium in the tube finally impacts back, the shock absorption tube 4 can utilize the contraction and expansion recovery potential energy of the self energy absorption block 8 to drive the whole shock absorption tube 4 tube wall to continuously keep the recovery process of the contraction in the tube, and finally the stable fall-back of the shock absorption tube 4 is realized.

As shown in fig. 1 and 2, considering that the impact force and the impact process of the medium flowing in the tube are uncontrollable in the actual use process, the thickness of the tube wall of the shock absorbing tube 4 is greater than that of the tube wall of the fixed tubes 5 at the two ends, and the good extension performance of the shock absorbing tube 4 is ensured. The liquid flow dredging layer 12 is also arranged in the shock absorption tube 4, the density of the liquid flow dredging layer 12 positioned in the middle of the shock absorption tube 4 is greater than that of the liquid flow dredging layers 12 on the two sides, and the liquid flow dredging layers 12 with different dredging densities can effectively guide and dredge the passing of a circulating medium in the tube, so that the turbulence phenomenon caused by the concentrated impact of the instantaneous circulating medium is reduced; and still be equipped with spacing guard circle 13 between sleeve pipe 2, spacing guard circle 13 inner wall is equipped with elastic buffer 14, can realize reliable stable outside weakening when can be acted on shock-absorbing pipe 4 department to some too big impact, reduces the too big atress deformation of energy-absorbing pipe part, ensures lasting reliable shock attenuation performance of weakening.

Because this coupling adopts flexonics, can take place the dislocation between energy-absorbing pipe and the fixed pipe 5 and slide, in order to reduce the leakproofness influence to the pipe connection head that this dislocation slides and probably bring, this fixed pipe 5 is equipped with cascaded buffer segment 6 with inhaling 4 junctions of shake pipe, can effectively reduce and inhale 4 partial shock attenuations of shake pipe and weaken the great displacement fall influence of in-process, be equipped with vacuum layer chamber 9 at the both ends of flexible body 1 simultaneously, the unnecessary shock wave of transmission in the whole flexible hose can effectively be absorbed in vacuum layer chamber 9, reduce this shock wave and act on between sleeve pipe 2 and fixed pipe 5, influence the connection sealing degree of the fixed pipe 5 department in both ends.

The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications of the present embodiment without inventive contribution as needed after reading the present specification, but all of them are protected by patent law within the scope of the claims of the present invention.
