Problems solved by technology

So there is a problem here: while forming a pitch rigid enough to accommodate a threaded connection, the plastic material does not provide much flexibility to the resulting tube due to the sheathing of the rigid metal helical tube

Embodiment Construction

[0032] figure 1 A one-piece flexible hydraulic connection is shown in , which consists of a deformable tube 1 and two rigid casing sleeves 2 to which a female joint for longitudinal connection is glued. The deformable pipe 1 consists of a part 3 which is a flexible pipe with a smooth inner wall and a thermoplastic pipe of the flexible PVC (polyvinyl chloride) type, which is inserted between two terminal sleeves 2 by mixing in during the production of this connection . The section 3 of the flexible pipe is surrounded by a series of hoops made of a rigid PVC-type thermoplastic. These hoops constitute support means, essentially enabling the flexible pipe part 3 to maintain its diameter during the connecting operation, regardless of the mechanical stresses exerted on the connection. Both rigid and flexible PVC according to the invention are chemically compatible, that is to say they can permanently anchor a series of rigid PVC hoops 4 in the section 3 of the flexible pipe of fle...

Abstract

The invention concerns a flexible hydraulic connection comprising a deformable tube (1) and two rigid sleeves (2). The invention is characterised in that the deformable tube (1) comprises a plastic pipe portion (3) with smooth inner wall, made of flexible thermoplastic material or thermoplastic or thermosetting elastomer, and a retaining device, enclosing said flexible pipe portion (3), consisting of a rigid plastic material and formed with a plurality of rings (4) or at least a helical coil.

Description

technical field [0001] The present invention relates to hydraulic connections, especially flexible hydraulic connections, such as drainpipe connections, which are used for the discharge of sanitary water, waste water, rainwater or toilet excrement and the like. [0002] A flexible hydraulic connection of this type therefore consists at least of a deformable tube and two sleeves or rigid pin or box for end connections. [0003] The invention also relates to a method of producing such a hydraulic connection. Background technique [0004] Hydraulic connections for hydraulic piping connections are usually all made of rigid material by molding PVC, ABS, polyethylene, polybutylene or polypropylene etc. They are usually made in one piece such as elbows, branches, Ys, sleeves, and more. In the case that the connection has an angle, when the angle of the connection is inconsistent with the current standard, such as 30°, 45°, 60°, 90°, in order to achieve coaxiality, the connection ...
