Description

Technical field

The claimed utility model relates to heating appliances, in particular, to bimetallic radiators used for space heating.

State of the art

Sectional bimetallic radiators are known and widely used. Unlike other sectional radiators, bimetallic radiators are characterized by the combination of aluminum shells of adjacent sections and embedded elements.

A known node for connecting sections of a bimetallic radiator, disclosed in RF patent 2172901 from 08.27.2001, with steel embedded elements and an aluminum alloy shell includes horizontal nipples of embedded elements of adjacent radiator sections tightened with a nipple and an annular seal compressed by the end surfaces of the aluminum shells, which are equipped, respectively , one - an annular protrusion, the other - an annular cavity, which is an annular seal. The location of the sealant implies the penetration of the coolant into the contact zone of the steel pipe and the aluminum shell and, accordingly, leads to a decrease in the quality of the joint sealing due to corrosion of the radiator sections at the junction, the reliability and service life of the radiator are reduced.

In the bimetallic radiator also known from the prior art, disclosed in RF patent No. 2351858 dated 04/10/2009, the connection unit of the bimetallic radiator sections with steel embedded elements and an aluminum alloy shell includes horizontal nipples of embedded elements of adjacent radiator sections tightened with a nipple and an annular seal compressed by end surfaces of horizontal nozzles of embedded elements and aluminum shells of adjacent sections. This well-known technical solution is the closest analogue of the claimed utility model.

At the same time, in this well-known technical solution, the location of the seal between the ends of the sections allows it to be pushed out by the coolant, which manifests itself when the seal is not compressed enough and pressure surges in the heating system, and also, as the seal loses its elasticity during operation. The penetration of the coolant into the contact zone of the steel pipe and the aluminum shell leads to premature corrosion and subsequent violation of the tightness of the connection of the sections of the radiator.

The claimed utility model is aimed at solving the technical problem of reliable sealing of the junction of the sections of the bimetallic radiator.

Utility Model Disclosure

The technical result achieved in the claimed technical solution is to increase the reliability of the tight connection of the sections of the bimetallic radiator.

The specified technical result is realized in the junction of the sections of the bimetallic radiator with steel embedded elements and a shell made of aluminum alloy, including the horizontal nozzles of the embedded elements of the adjacent sections of the radiator tightened by the nipple and an annular seal compressed by the horizontal pipes of the embedded elements of the adjacent sections, with each horizontal pipe of the embedded elements of the adjacent sections is made with an annular ledge adjacent to the end of the pipe with outer and inner diameters large, respectively, of the outer and inner diameters of the rest of the horizontal pipe, and the ring-shaped seal is located inside the ring ledges of the horizontal pipes of the embedded elements of adjacent sections.

An O-ring may be located on the outer surface of the nipple.

The protrusions made on the inner surface of the nipple and designed to twist the nipple when pulling the horizontal pipes of the embedded elements of adjacent sections of the radiator can be offset relative to the plane of the O-ring on the outer surface of the nipple.

An annular groove may be formed on the outer surface of the nipple, in which an annular seal is mounted.

Horizontal nozzles of embedded elements of adjacent sections can be joined to each other by their end surfaces. In this case, the outer surface of the annular ledges adjacent to the ends of the horizontal pipes of the embedded elements of adjacent sections may be coated with an aluminum alloy shell.

The outer surface of the annular ledges of the horizontal pipes of the embedded elements of adjacent sections can be made without an aluminum alloy shell.

Brief Description of the Drawings

In FIG. 1 shows a section through a lower joint assembly of adjacent sections of a bimetallic radiator. The outer surface of the annular ledges adjacent to the ends of the horizontal pipes of the embedded elements of adjacent sections is covered with a shell of aluminum alloy.

In FIG. 2, the connection assembly shown in FIG. 1 is shown on an enlarged scale.

In FIG. Figure 3 also shows, on an enlarged scale, a section through a lower joint assembly of adjacent sections of a bimetallic radiator, but the outer surface of the annular ledges of the horizontal branch pipes of the embedded elements of adjacent sections is made without an aluminum alloy shell.

Utility Model Implementation

The connection unit of the sections of the bimetallic heating radiator, shown in figures 1, 2 and 3, consists of horizontal pipes 1 and 2 of steel embedded elements of the adjacent sections of the radiator, nipple 3, screwed into the pipes 1 and 2 and tightening them, and an annular seal 4 mounted on nipple 3 and between nozzles 1 and 2. The connection node at the bottom of the sections of the bimetallic heating radiator shown in the drawings is identical to the connection node at the top of the sections of the bimetallic radiator.

The nozzles 1 and 2 are made with annular ledges, respectively 5 and 6, adjacent to the ends of the nozzles 1 and 2, joined to each other. The annular seal 4 is located inside the ledges 5 and 6, covering the outside of the seal 4, covering the nipple 3. When tightening the nipple 3 of the nozzles 1 and 2, the compression ratio of the seal 4 is not more than 30-35%. With increasing pressure of the coolant, the seal 4 is pressed against the walls of the annular ledges 5 and 6 and, thereby, even more tightly seals the joint of the nozzles 1 and 2, while maintaining the sealing connection of the sections of the radiator.

The formation of annular ledges 5 and 6 adjacent to the ends of the nozzles 1 and 2, perform the punch and, if necessary, the subsequent boring in a predetermined size. After the formation of annular ledges on the horizontal pipes and welding of the embedded elements, an aluminum shell is formed by injection molding, which, as shown in FIG. 1 and FIG. 2, covers the outside of the annular ledges on the horizontal nozzles. However, it is possible not to cover the annular ledges on the horizontal nozzles with an aluminum sheath, as shown in FIG. 3.
