Arrangement for the end-face connection of tubular parts

The invention relates to an arrangement for connecting axially aligned tubular parts of all kinds, for example insulating cladding parts for pipelines.

The invention is intended to be an easy to install and remove Connection arrangement created for tubular parts xerden, which seals the joint between the parts made possible with simple means and very low costs.

According to the invention, this object is achieved by an arrangement which has the following features: resilient metallic material clip in the form of a split ring; to the to be connected

Means disposed ends of the tubular members encompassed by the built-in bracket; at the Clamp provided means which come into engagement with the means of the tubular members so that they move the ends of these parts in the longitudinal direction and bring them into face-to-face contact; and means to releasably attaching the bracket to the circumference of the tubular parts.

The means provided on the clamp are preferably those arranged at the ends of the tubular parts Means include opposing baffles disposed on the inside of the central bracket area.

Those arranged at the ends of the tubular parts to be connected Devices can consist of radially extending flanges.

The deflection surfaces arranged in the middle area of the clamp are preferably arranged in a V-shape, while the side areas adjoining the central area of the clamp are ring flanges resting on the outside of the tubular parts.

Preferred embodiments of the invention are set out below described with reference to the drawing. In the drawing is:

Pig. 4 is a sectional view similar to FIG. 3 a modified embodiment of the insulating parts; and

5 is a sketch-like representation of the mode of operation of the assembly of the arrangement parts to be connected;

When building nuclear power plants and other plants in which longer pipelines are provided with insulating cladding are, the pieces of insulation must be able to be joined together in a simple manner so that their opposite ends are close together.

To make it easier to attach the insulation to the lines, the cladding is made of preformed, stretched lengthways the line extending portions formed, the ends of which must be firmly connected to each other. To do this achieve, an arrangement is provided according to the invention, in which a band-shaped clamp the abutting one another Overlaps ends of the sections.

Figure 3 shows a pipe 10 of circular cross-section, which is surrounded by lining pieces 11, which consist of a Number of insulating mats 12 are made. The sections are outside and inside of metallic wall covers 13 and and 13 'and 14' respectively.

The trim pieces 11 are normally made up of spacers 15 held at a certain distance from the tube 10.

The outer turning cover 13 of the cladding piece shown on the left in FIG. 3 has a radially protruding end flange 15 which is opposite a corresponding radially protruding end flange 16 ^{1 of} the outer wall covering 13 ′ of an axially adjoining cladding piece 11. The cladding piece is made of metal on its front side

existing cover plate 17 provided with the inner surface the inner wall cover 14- 'by a splash 18 connected is. The cover plate is located near the end flange 16 ' 17 with an angled stiffening ring 19 Mistake.

The opposing, outwardly bent flanges 16 and 16 ^{f of} the cladding piece 11 are encompassed by a band-shaped or clamp-shaped clamp 20 in the form of a split ring. The bracket 20 consists of a strip of resilient metal. The radius of the ring clip is preferably equal to or slightly larger than that of the insulation. The clip can consist of a single metal strip or, if this is necessary because of its size, of two strips connected by a hinge.

As shown in FIG. 1, the band-shaped clamp 20 has an outwardly projecting central region 21 with a triangular cross-section, the inner walls of which form cam or deflection surfaces 22 and 23, which lie opposite one another. At their lower ends, the deflecting surfaces 22 and 23 merge into annular flanges 24 and 25 which extend laterally in opposite directions. These hanging flanges 24 and 25 lie on the outside of the outer wall coverings 13 ″ and 13 ′ and contribute to better thermal insulation at the junction of the cladding pieces when the clamp is installed (see Fig. 3-5)

When the band-shaped clip 20 is placed around the junction of two axially aligned trim pieces

is and is then contracted, the arrive radially projecting planes 16 and 16 'in contact with the deflecting surfaces 22 and 23 and are moved towards each other until they hit each other. The bracket is then properly attached. The insulating lining pieces 11 are now in the axial direction with each other aligned and form a continuous insulation for the pipe 10.

A spring lever-like locking device is used to tighten the band-like clamp 20 on the circumference of the cladding pieces 11. This device has a closing plate 26, which by means of a U-shaped bracket 27 on the Annular flanges 24 and 25 of the clip near one end thereof is attached. Near the other end of the bracket 20, a U-shaped plate 28 is attached, on which a locking plate with two radially outwardly projecting paddles 30 and sits.

On one between the paddles 30 and 31 extending Shaft 32 is a locking lever 34 with a locking hook 33 arranged. The free end of the locking hook is designed so that it fits into an opening 36 of the locking plate can enclose. If the locking lever 34- then in a position adjacent to the clamp is pivoted, the two ends of the clamp take the position shown in Pigur 1, overlapping position. When the clamp is closed, the radially bent puddles move 16 and 16 'in the manner already described relative to the baffles.

In Pigur 4 there is a modified embodiment of the one end of an insulating panel covering device is shown. In this embodiment is at one end of an insulating cladding piece 37, a metallic face plate 38 is arranged, the one

Legs of an angled profile ring 39 engages behind. These Arrangement is covered by a second metal plate 4-0, which has a flange attached to the inner wall cover 4-2 41 has.

The invention can also be used for rigid tubular components Find use and is not limited to the embodiment described limited. Many modifications to the embodiment described are possible. So can parts the locking device arranged to be adjustable or exchangeable (for example locking hooks of different Length) be formed around the bracket tubular components to be able to adapt with different diameters. If necessary, seals can also be used in the connection arrangement be provided.
