专利说明:

the stroke between this value C and the stabilized compression after 24 hours is very weak.
The duration of the operation between closing the mold containing the ends of the flexible pipes with the connecting device and removing the kit from is less than 1 minute.
Fig. 2 shows an internal pattern of cuttings 1 for connecting two flexible pipe joints consisting of rubber-based mixtures of the same or different shape :; Internal pipe 1 contains a flange G that serves as a stop d IKOHHOI installed flexible pipelines 1T,
Fig. 3 also shows the straight line.
internal nozzle 1. the contents of the cleaning device 3, which allows the linear connection of two flexible pipelines consisting of rubber-based mixtures of the same or different forms,
Fig. 4 clarifies the simple branching: using a T-shaped pipe 1, allowing flexible pipe to be connected to the main pipe. Internal pipe 1 is provided with recesses 4, which facilitate mechanical attachment of the main pipelines or branches to the internal pipe. 2, The number of shape, depth and location of the grooves 4 are adapted to reinforced or unsuccessful mixes of rz-based rubber. The p which consists of connected flexible pipelines to provide the best mechanical connection.
In order to increase reliability and connection, a sticky bond can be used between the internal nozzle 1 and the ends of the main flexible pipelines and branch lines,
Fig, d) shows the use of the device with the main, clean or cold cleaning device. Flexible pipes 5 are installed at the ends of the straight narpv6K3 1, containing the cleaning device 3, up to the stop in the flange 2.
After the outer covering element 6 is installed in place, the compression of the stored polymer ensures the fitting of the wall of the flexible pipelines 5, zones FK4, while the wall is clamped between the rigid internal branch pipe 1 and the external covering element 6.

FIG. 6 illustrates the use of a coupling device for branching. The main flexible pipelines and branch pipelines 5 are mounted on the corresponding branches of a rigid internal branch pipe 1 of the T-shape up to the stop on the flanges 2.
In this case, the external enclosing element 6 is formed in the described conditions for pressing the walls of the ends of the flexible pipes 5 to the rigid internal nozzle 1. In this embodiment, the internal nozzle 1 of the T-shape has recesses 4 which improve the mechanical connection with the ends of the main and return flexible pipelines 5.
FIG. Figure 7 shows the use of a compound tap device.
Between the rigid inner branch pipe 1 is X-shaped and the internal coating of the ends of the flexible pipes 5, as well as between the external enveloping element 6 and the external coating of the ends of the flexible pipes 5, there is an adhesive, and the adhesive can be identical or different in composition depending on the type of rubber-based mixtures from which flexible pipelines are made.
FIG. Figure 8 shows the use of a coupling device for mounting in the same zone of one branch and one cleaning device 3.
FIG. Figure 9 shows a device for connecting a simple pipe 5 with a conventional metal tip 8 of an instrument or engine mechanism, and the tip 9 must be removable to be placed in a mold together with the end of the flexible pipe 6, since it plays the role of an internal nozzle.

1. A method of manufacturing a connecting and / or branch device for flexible pipelines, comprising placing the end of a flexible pipe on an inner tube having annular bulges on the outer surface, casting in the form of an outer polymer element, fixing it on the outer surface of the pipeline in its zone connection and, simultaneously with this, hot fitting of a flexible tube JQ to the internal branch pipe, characterized in that, in order to increase reliability and facilitate the fitting of the ends of the flexible pipelines, the element is subjected to a thermo-15
processing and cooling until shrinkage is at least 1%.
2. A connecting and / or branch device for flexible pipelines, comprising an internal rigid branch pipe with annular bulges on the outer surface, a flexible pipe fixed thereto and a plastic crimping element, so as to increase reliability and ensure easy donning flexible pipelines, the crimping element is made of polyamide 66 with a shrinkage ratio of at least 1%.
