Description

Dirt traps for pipes These are dirt traps for pipes for many years for a wide variety of operating conditions for installation in pipelines known for water, steam, gas air, etc., but which are always of particular importance a cleaning facility was laid.

Due to this requirement, there was always a cover flange arranged on the side with access to the sieve required. However, this arrangement forces constructions some of which are very bad in terms of flow.

Furthermore, these types of construction have the disadvantages that they are suitable for high operating pressures executed as a single piece, are very expensive. The cost of such mud flaps are often not wearable.

The advancing automation in the industry demands one increasing use of regulators and sensitive devices that protect against dirt are very sensitive.

Often there is only a relatively small amount of dirt, which but can still cause sensitive disturbances.

The dirt trap described below is for this application thought.

Since relatively little dirt is expected, a The possibility of cleaning from the outside is not provided. It is accepted that the entire section of pipe is removed if too much dirt has accumulated Has.

According to Fig. 1, the housing consists of a straight pipe section (1) in which a conical strainer basket (b) is used. The peculiarity of this The dirt trap lies in the good flow conditions of this design. Included It is important that the annular flow cross-section between the strainer basket and the housing is enlarged to the extent that the sieve area exposes the usable cross-section gives. At the end of the strainer basket, the circular ring should have the cross-section of the nominal width.

It is thus achieved that the flow velocity in the ring cross-section approximately the same size at every point along the length of the sieve will and no There are dead corners that can cause turbulence and thus pressure loss are.

Another construction, which also has the desired effect, is shown in Fig. 2 Here, too, the outer flow cross-section takes place in the Dimensions to7 as shown by the sieve cross-section.

This was achieved through the conical shape of the housing. The sieve itself is cylindrical and is therefore cheaper to manufacture. There The usable surface area is larger in the case of these cylindrical sieve bodies this design, the overall length can be kept shorter.

In order to also ensure a good flow path in the sieve inlet the strainer basket (b) can still be fitted with a cone (c) for the purpose of better Flow guide, instead of flanges, the dirt traps can also be manufactured with threaded sockets.

Protection claims: 1) Dirt trap for pipelines characterized by that the dirt trap consists of a piece of pipe with flanges, in which centrically a Siebkob is used without a cleaning cover to the outside.

Claims (1)

2) dirt trap for pipes according to claim 1, characterized in that that the sieve or the housing is designed conically so that the flow cross-section behind the sieve at each point of the sieve the usable cross-section of the one in front Sieve part corresponds
