Steam trap with egg metal control element

Steam trap with one made of bimetal discs

existing control organs are in various ways

( guide forms known. The well-known steam water

arresters of this type require a considerable amount of material and work and are therefore relatively expensive.

The innovation is therefore based on the task of one To create steam water trap of the type mentioned, which is very simple and therefore considerable Can be produced cheaper than previously known steam traps for comparable performance and Pressure areas and in which the arrangement of special guide means for the bimetal disks is unnecessary.

The solution to this problem is, according to the innovation, essentially that the housing of the arrester by a tubular steel jacket and two with the ends of this maüt / Slä vsrGCiivvsißtsii, made from blsichgefornrbfin blanks manufactured Kohrleitungs connection parts is formed.

These are the cylindrical housing designed in this way Valve closing piece and a bimetallic disk package arranged on the valve stem by a likewise arranged on the valve stem, reaching up to the inner wall of the housing shell, polygonal Disc guided centrically.

The steam water drain that is designed in this way can be made with extremely simple means and therefore extremely inexpensive produce. Time consuming and costly repairs that can occur after long periods of operation would be uneconomical in the steam water trap according to the invention; rather, in these cases there is an exchange a defective one against a new arrester easier and cheaper.

Further details of the new steam trap are available from the following description and the drawing of an exemplary embodiment as well as from the subclaims.

Fig. 1 shows a longitudinal section through the housing of a steam water formed according to the innovation arrester s ",

After the innovation, there is the housing of the steam trap from a tubular steel jacket 1 and two welded to the ends of this jacket, made of the same shape

exhibit.

In the housing constructed in this way, a valve closure piece 4 and one on its shaft 41 are arranged Biaietallscheibepaket 5 by a likewise on the Valve stem 41 arranged disc 6 guided centrally, which in the illustrated embodiment, the shape of a square with broken corners and with these corners close to the inner wall of the steel tubular jacket 1 reaches.

The disk 6 is preferably made of bimetal, like the other disks of the package 5, can but also be made of other material.

The parts 2 and 3 each have a frustoconical projection 22 and 32 on their inside. ^ n the ledge 22 of the part 2 are at least two opposite, obliquely against the inner wall of the housing part 1 directional bores 23 are provided, while the projection 32 of the part 3 slotted radially is and as an abutment for the bimetallic disk package 5 serves.

The valve seat is formed by a step 33 of the through central bore provided in the housing part 3 educated.

The threaded hole 21 of the housing part 2 is used to connect a supply line, the threaded hole 31 of the Part 3 for connecting the steam water discharge,

The bores 23 of the housing part 2 directed obliquely against the inner wall of the housing jacket 1 cause that the bimetallic disk package after derivation of the steam water is not directly affected by the dynamic pressure of the often flowing in at high speed Steam is applied, as this dynamic pressure causes an undesirable delay in sleep could be.

Commercially available seamlessly drawn steel tube that does not require any mechanical reworking can be used as the starting material for the housing jacket 1. The smooth inner wall of this steel tube runs parallel to the valve seat bore and thus forms, by means of the disk 6, a simple and perfect guide for the bimetal disk package 5 and the valve stem 4-1. The mechanical reworking of the housing parts 2 and 3 is very simple and requires only a small amount of work.
