Description

/ ^ Attachment of large-lumen tubes 'on flange sleeves /,

The! Inflation deals with the fastening of large-lumen hoses medium pressure level on facing sleeves with radial ring projections and an adhesive connection between the sleeve and the hose.

Hoses with fastenings of this type are used "in the case of earth drilling or used in the bunkering of liquids. The hoses have a diameter of about 5 - 3ocm and the occurring ones Pressures range between 1o and 3 ° atu. For this Hose types and these types of stress are known for the fastening of flange sleeves in hoses in several designs. In the case of simple designs, the hose end is pushed over the sleeve up to the flange and between the radial ring projections There are wire cuffs or cuffs for fastening. The latter have the gate part that they are leaking the fastening can be retightened. However, they tend to be a hindrance to others because of the protruding reinforcements Machine parts. On the other hand, a wire winding can be so damaged by impact or blow-out that the entire wire bond is damaged detaches and thereby the attachment between the hose and the flange sleeve is canceled.

In another type of fastening, fastening means have been introduced into the walls during the manufacture of the hose. These fasteners are not superficially visible, and they in this way reduce the risk of accidents. With such fastenings, tapering of the sleeve end is sometimes provided, However, it is disadvantageous that the flowing liquid can penetrate in one direction between the hose and the sleeve and the hose wall gradually loosens under the constant pressure from the sleeve, even if a good, firmly adhering connection between Consisted of rubber and metal.

The object of the invention is to provide a secure and tight hose fastening to propose that does not have the disadvantages listed above and is suitable for the intended purposes is.

The solution to this problem is that the face sleeve on the end that extends into the hose is above the cylindrical The sleeve part has a cylindrical flange sleeve, which is connected concentrically and coaxially with a pressure-tight seal, outside the liquid space having. The flat sleeve over the flat sleeve ensures that if the rubber that adheres on all sides becomes detached the pressure in the hose blocks itself the way into the cavity between the sleeve and the sleeve. Namely, if the liquid from If you are clever, you press the rubber from the surface of the wedge sleeve, there will inevitably come a point in time when the next Separate the adhesive connection against your own pressure got to. This occurs when the separation of the adhesive connection has reached the inner edge of the flat socket. Have experience too shown that the interaction of the face sleeve and face sleeve according to the innovation significant stresses and dynamic mechanical type has grown without causing damage, as occurs repeatedly with other fastenings.

The price increase is the flat sleeve on the inside of the hose widened conically. The purpose of this design is that during the manufacture and subsequent vulcanization of the hose on the Planschmuffe the rubber compound is better pressed into the cavity. On the outside, the flat sleeve is designed to be cylindrical so the construction and the connection between the hose and the facing sleeve is facilitated.

The face sleeve has radial labyrinth grooves on the inside of the cone on. These strengthen the adhesion in local areas between rubber and metal.

The flange sleeve is conically tapered at the end on the outside below the flange socket, so that the flow processes during Assembly and vulcanization are made easier.

The double-conical cavity between the sleeve and the sleeve has a greater axial length than the maximum radial clearance Width corresponds. This measure ensures that the pressure distribution when initiating damage is sufficiently large, to effectively prevent further detachment. The ratio between the axial length and the radial width is preferably 2: 1 to 3: 1.

The sleeve part lying under the plane sleeve can be used as a separate Ring be formed. While the inner wall of this ring is aligned with the interior of the wedge sleeve, the can The outer wall can be designed to be cylindrical, conical or double-conical. The task of this sleeve is to facilitate the production of the attachment.

Figures 1 and 2 illustrate the control in cross-sections, each of which shows one half of the hose attachment.

Flange 1 and sleeve 2 together form a flange sleeve on which the hose is attached. The hose consists of an inner rubber layer 3 "reinforcement 4" another rubber layer 5, the reinforcement insert 6, the spiral 6a and the upper rubber 6b At the end of the facing sleeve 1, 2 there is a facing sleeve 7 »which is coaxial, is connected concentrically and pressure-tight with the flange sleeve 1, 2.

Sleeve 2 is conical in shape.

Flows from the adhesive bond, for example Item 15 outflowing liquid, with progressive elimination If the adhesive connection enters the space 11, the liquid medium at_Ankuft at the annular surface I4 becomes the rubber compound 11 pressed against the surface 1o. This results in a further detachment of the rubber compound from the flange socket 7 locked out. Even dynamic loads cannot affect this automatic pressure lock.

Figure 2 differs from Figure 1 in that the The sleeve part located under the flange socket 7 is designed as a separate ring 16. This will build up the hose on the flange sleeve. The ring 16 has double cones Shape and lies close to the sleeve 2.
