Component of a tubular switchgear. - Construction and maintenance of the vehicle.

In current pipe installation technology, especially in HVAC installations, there is a common method of installation in which the connecting cables are distributed from the central location of the applications to the applications, faucets or radiators.

At the junction / branch point of the supply lines and connecting lines, a multi-branch pipe section is used - a manifold.

The manifold can be one-piece, one- or two-sided branching, or two-piece one- or two-sided branching. In the case of tubular manifolds, the need to use two wrenches when tightening the connecting nuts is a disadvantage of the installation phase. The other holds the connector body attached to the manifold so that the manifold is not damaged by another torque of the wrench tightening the nut.

20 In the case of two-piece manifolds, there is a need to keep the parts together so that they form a fixed, durable assembly that is easy to handle and fasten.

The invention relates to a component and a way of assembling the manifolds so that the disadvantages described above can be eliminated.

The features of the invention to achieve this object are set out in the appended claims.

The structure according to the invention will now be described with reference to the accompanying drawings, in which Figure 1 shows a two-part, double-sided manifold provided with a component according to the invention as seen from the side and end.

Figure 2 shows a side and end view of a two-part, one-sided manifold provided with a component according to the invention.

Figure 3 shows 5 sections taken along the line III-III in Figure 1.

Figure 4 shows the manifold according to Figure 3 in the direction IV-IV.

The structure according to the invention will now be described with reference to the accompanying Figure 1, which shows a two-part, double-sided manifold. Parts 1 and 2 are the manifold body parts supply / return or hot and cold water pipes. Part 3 is branch pipes which are crosswise symmetrical in pairs 15 in the supply / return line, whereby the connecting nipples 4 of the connecting lines come into line with each other.

In the embodiment according to the invention, the base part of the nipple 4 is extended at an angle so long that grooves 6 can be made in it for the retaining rings 6a. The distance between the grooves 6 should be so large that there is a connecting rail 5 between them with holes corresponding to the base of the nipple 4 and which in turn is so strong that it receives the forces from tightening the nut 7 preventing the branch pipe 3 from rotating. The distance between the grooves 6 and the thickness of the connecting rail 5 should be chosen so that the retaining rings 6a prevent the rail 5 from moving and tilting relative to the nipple.

The shape of the rail 5 is most preferably bent at an angle, 30 forming a mounting bracket for the manifold, in which dimension 9 can be chosen as appropriate and the desired fastening screw holes 8 are obtained on the bent side.
