SU14034A1 - Device for connecting cast iron pipe economizer with cast iron manifolds - Google Patents

Description

The present invention relates to a device for connecting cast iron economizer tubes with cast iron manifolds, using a flare ring for this purpose.

In FIG. 1-3 depict various embodiments of the above device in section. XJ FIG. 1 represents compound re-. economizer pipe 1 with a collector 3 using an iron ring 2, reinforced by flared in annular grooves, which are located both in the widened part of the pipe and in the tide of the vector. tubes with a tubular liner 4. The latter is provided with flanges that serve to remove the liner through the cleaned manhole cover by means of a screw fixture (shown in dotted lines in the drawing). In the case of galvanizing the designated iron ring or in the case of its manufacture instead of iron, for example, from red copper, stainless steel, etc. of materials, special protection is not required;

FIG. 2 depicts a modification of the proposed device, consisting in

that the pipe 4 and the collector 5 are interconnected by a flared iron ring 3, which, as in the previous case, is protected by a liner 1, and the gap between the liner and the ring is filled with cement mortar 2.

FIG. 3 represents another modification of the described device, consisting in that the flared ring 1 connecting pipe 2 and collector 3 is protected by an insert 4, which is secured on its ribs with a support surface and held in its slot with a bolt 5, which bolt passed through the cover 6 of the cleaning hatch. The seal of the joint is achieved by applying an elastic gasket 7 under the lock nut 7 Subject of the patent.

Claims (3)

1. A device for connecting cast-iron economizer tubes with cast-iron manifolds, characterized by the use (Fig. 1) of a reinforced expanding iron ring 2, covered with the purpose of eliminating corroding of this ring, with a tubular liner 4 provided with its corresponding edges. 2. A change in the device according to claim 1, characterized by the use in the gap between the iron ring 3 (Fig. 2) and the inlay 1 cement filling 2. 3. The device change according to claim 1 and 2, which can be distinguished by the fact that the insert 4 (Fig. 3), provided on the ribs with a support surface, presses against its nest by acting on this surface of a bolt 5 passing through the cleaning hatch 0 of the hatch.
