Description

The utility model relates to a double-walled pipe or Vessel made of glass or a glass-like, brittle material, in particular is intended for operational use and for this purpose, in contrast to laboratory devices with correspondingly large Dimensions to be made. :

In order to be able to control arm tensions occurring when double-walled devices made of glass are loaded with media of different temperatures, it has already been suggested that the outer jacket of such double-walled glass tubes or feet should only be on to fused one end to the .ioiir- or vessel wall, him at the other hn-1!

occur, it is known to be the outer tube or an outer Vessel jacket at both ends by means of stuffing boxes and union nuts or to seal clamping rings on the inner tube or on the inner vessel so that the possibility of separate expansion of the adjacent Parts is secured. The well-known elastic connections by means of glands and union nuts or Clamping rings are cumbersome and have the disadvantage that at each end of the outer jacket by the required length the stuffing boxes or other elastic seals a viesential Part of the pipe or vessel length for the heat transfer is lost,

The utility model is based on the task of double-walled tubes or vessels made of glass or glass-like materials to be designed so that the outer jacket zvrisehen separately from the pipe or vessel and dispensing with a fusible link The parts can be manufactured and the parts are connected at one or both ends by elastic seals that only require a small axial length4 ^ and the Heat transfer between the pipe or vessel and its outer jacket not significantly impaired

This object viira achieved according to the invention in that the Outer jacket closes the pipe or vessel wall without contact at both ends with drawn-in edges and the elastic one Connection made by seals cast into these countries is. Stuffing boxes, union nuts or clamping rings thus come to an end.

In a preferred version of the utility model is the Außenmanbel designed so that he the pipe or vessel wall at one or both ends with an edge of V-shaped cross-section, in which the seals from the outside and / or are cast from the inside.

V / eist the outer jacket at least one lateral itohrstutzsn on, it can be sufficient if it has no outer openings at its ends and the seals for both ends of the outer jacket are introduced into the outer jacket through the lateral pipe socket.

The drawing shows examples of the execution of double funds. Glass tubes or vessels according to the utility model, and ' although show

Pig. 1 shows a double-walled glass tube in longitudinal section with seals arranged within the glass jacket ^; and :

The glass fitting nac ^H h Figure 1 consists of a technical operating in% dimensions nergestellten inner tube 1 which is provided with a likewise made of glass, however, produced separately from the inner tube outer shell. 2 The outer jacket is provided at both ends with drawn-in edges 3 »^ which enclose the inner tube 1 without contact at a small distance. The gap between the ends of the outer jacket and the

Inner tube 1 are closed by elastic seals 5, which are inserted through the lateral connection pieces of the outer jacket in the jacket space k »The seals are preferably made of silicone rubber, If necessary, the annular gaps can be temporarily closed from the outside by a collar when pouring the sealing material. Pouring; the seals in the shell space and their inner support on; <i |, i, the drawn-in ends of the outer shell 2 has the advantage that the seals are pressed against their seating surfaces when pressures occur in the shell space k, increasing the seal pressure.

In the embodiment according to Pig, 2, the outer jacket 2 sitting on the inner tube 1 'is provided at its ends with drawn-in edges, which have a V-shaped cross-section on v / iron and into a -; Skip outer extension 6 «The sealant 7 is here; cast from the outside into the conical extensions 6 of the drawn in] bands. The manufacture of the glass fitting is carried out here- | facilitated by and is particularly suitable for those cases in which the medium to be conducted through the jacket space k is exposed to fine pressures, which could impair the durability of the seal »

The outer shell V / eist the embodiment of FIG. 2, so also the seals of FIG. 1 and FIG 2 can come _c as inner and outer seals together for use in case of need "
