Description
Technical field
The utility model relates to cushion technique field, particularly a kind of for delivery of concrete rubber shock-absorbing larynx.
Background technique
Rubber shock-absorbing larynx, for playing the hollow rubber goods of immunity connection function between metallic conduit, is called again rubber compensator, and rubber shock absorber etc., are a kind of high elasticity, high-air-tightness, the pipe coupling of resistance to medium and weathering resistance.This product takes full advantage of the advantages such as elasticity, high-air-tightness, media-resistant type, weatherability and the radiation resistance of rubber.Be divided into three kinds of lap joint flange formula, fastening flange formula and thread types by Placement, can be divided into five kinds, single spheroid, two spheroid, reducing body, curved spheroid and blast coil pipe etc. by structure.Generally form tubular rubber part by rubber and steel traveler, after high pressure, die material sulfidization molding, form with metal flange or splice combinations again.This product can reduce vibration and noise, and can, to the redeeming of expanding with heat and contract with cold causing because of temperature variation, be widely used in various pipe-line systems.
But the rubber shock-absorbing larynx that market produces is at present all by forming with metal flange or splice combinations after tubular rubber part sulfidization molding again, in concrete course of conveying, shake very large, be easy to cause rubber shock-absorbing larynx to break at the place of being connected, sealing and damping effect obviously decline, and also can make concrete flow out, not only cause concrete loss, and in building-site construction, be easy to cause construction dangerous, to site operation personnel's the personal injury that causes.
Summary of the invention
Object of the present utility model is in order to solve above-mentioned the deficiencies in the prior art, thus provide that a kind of damping effect is obvious, sealing is reliable and stable for delivery of concrete rubber shock-absorbing larynx.
To achieve these goals, the designed one of the utility model is for delivery of concrete rubber shock-absorbing larynx, comprise ring main body, the upper and lower two ends of described main body are respectively equipped with main body coaxially with the O ring joint of internal diameter, on described joint, be evenly distributed with some fixed holes, described main body is respectively equipped with interior glue wearing layer outward by interior, main body enhancement layer, middle glue framework layer, main body enhancement layer and outer compound protective layer, described joint is by the interior steel disc layer that is respectively equipped with outward, joint enhancement layer, steel disc layer, joint enhancement layer, steel disc layer and joint protective layer, described joint enhancement layer is extended out by main body enhancement layer and is one-body molded, described joint protective layer is extended out by interior glue wearing layer and is one-body molded, described joint protective layer is also coated on joint excircle.Due to joint protective layer and interior glue wearing layer, joint enhancement layer and main body enhancement layer one-body molded; and joint protective layer also butt joint cylindrical protect; instead of form with metal flange or splice combinations again after tubular rubber part sulfidization molding; greatly improve the tightness of damping larynx, and ensured the damping effect of damping larynx.
Further, the thickness in the middle of the Thickness Ratio at described middle glue framework layer two ends is little, and the thickness in the middle of the Thickness Ratio at described outer compound protective layer two ends is large, and this is provided with the moulding being beneficial between damping larynx main body and joint.
Preferably, in described middle glue framework layer, be evenly distributed with steel wire, improve the damping effect of damping larynx.
Preferably, described enhancement layer adopts nylon cord fabrics rubberizing to form.
Further; described main body enhancement layer has four layers; and be uniformly distributed in middle glue framework layer both sides; thereby make described main body by interior interior glue wearing layer, main body enhancement layer, main body enhancement layer, middle glue framework layer, main body enhancement layer, main body enhancement layer and the outer compound protective layer of being respectively equipped with outward, in described joint has, be respectively equipped with outward steel disc layer, joint enhancement layer, steel disc layer, joint enhancement layer, steel disc layer, joint enhancement layer, steel disc layer, joint enhancement layer, steel disc layer and joint protective layer.Multilayer enhancement layer is set, is conducive to improve the anti-stress ability of damping larynx, thereby improve the damping effect of damping larynx.
Should be for delivery of the preparation method of concrete rubber shock-absorbing larynx: first by the interior glue wearing layer vulcanizating, main body enhancement layer, middle glue framework layer, main body enhancement layer and outer compound protective layer are arranged outward by interior, by the joint protective layer being extended out by glue wearing layer in main body vulcanizating, steel disc layer, the joint enhancement layer being extended out by main body enhancement layer, steel disc layer, the joint enhancement layer being extended out by main body enhancement layer and steel disc layer ecto-entad arrange, and joint protective layer covers on joint excircle, adopt the hot sticky compacting of adhesive one to form, the length of the Length Ratio main body enhancement layer of described interior glue wearing layer is long, in the Length Ratio of described main body enhancement layer, the length of glue framework layer and outer compound protective layer is long.The rubber shock-absorbing larynx forming by the hot sticky compacting of the method does not have gap, long service life, reliable in quality.
In the time having concrete to pass through in damping larynx, owing to there are many angular sandstone etc. in concrete, can cut damping larynx, greatly reduce the working life of damping larynx, at internal layer, interior glue wearing layer is set, and can increase the working life of damping larynx; In middle glue framework layer, being provided with steel wire, there is certain elasticity in steel wire, can improve the damping effect of damping larynx.
The one that the utility model obtains is for delivery of concrete rubber shock-absorbing larynx; its technique effect is: this rubber shock-absorbing larynx; main body enhancement layer and joint enhancement layer are one-body molded; interior glue wearing layer and joint protective layer are one-body molded; joint protective layer butt joint excircle is protected; can improve tightness and the damping effect of damping larynx, and the risk causing can reduce delivering concrete time.
