SU43140A1 - Method of making radiator element from etternit consisting of separate pressed halves - Google Patents

Description

Eternite (asbestos-cement) radiator elements for central heating replace cast iron elements and can be used both for water heating and steam heating with a working pressure of steam or water up to three atmospheres.

The thermal effect of eternit radiators approaches that of cast iron radiators.

The proposed method for fabricating FROM eternit of a radiator element from individual pressed halves consists in that the halves of extrusion pressed from sheets of etternit are stamped along the seams into a whole radiator element section. This achieves the correct distribution of asbestos fibers in the mass and obtaining, due to this, dense and fine adhesions.

In FIG. I depicts a front view of a rvdator made from individual elements of eternite; FIG. 2 is a top view of it with a partial section; FIG. 3 is a cross-section of the section according to AB in FIG. one; FIG. 4 is a view of half of the element from the inside.

The radiator shown in the drawing is, like the cast iron one, of the individual sections assembled in any quantity, depending on the required heating area and does not require any (364.)

POINT, no cuts, no metal nipples with left and right threads.

Radiators can be made of different heights, which is not revoked on their resistance to internal pressure. Each section consists of two halves I, 2, which are pressed separately from sheets of eternit. The two halves of the stamps are then put together with the help of special stamps by the planes 3 left in the manufacture of the halves not stamped.

For a better and more durable flatness of the 3 planes in the stamps, recesses and bulges are arranged in these places so that the recess of one half corresponds to the bulge in the other, which gives the planes with better grip.

To connect the individual elements of the sections to the radiator, take two ends of gas pipes 4 of length corresponding to the number of sections of which the radiator is to be composed. A cork 5 with an internal thread is screwed onto one end of each pipe and metal curved washers are strung on thin rubber or cardboard gaskets 7. Then they are strung on these pipe sections, placed between the dogs.

in joints with the same gaskets 7. After that, pressed metal washers b are laid and ordinary couplings 8 are screwed up, which press the linen strand on the minium to the washers and compress the sections between themselves.

The left free ends of the threaded pipes 4, coming out of the sleeves 8, serve to connect to the heating network. The ends of the gas pipes are drilled

in several places 9 and serve simultaneously as clamping bolts and for the passage of water or steam into the radiator.

The subject matter of the invention.

A method of making a radiator from a etnite, consisting of individual pressed halves, characterized in that these halves are stamped along the seams into a whole radiator element - a section.
