DE7830483U1 - FILTER OR SCREENING STATION FOR A PIPING SYSTEM FLOWING LIQUID OR GASEOUS MEDIA WITH INTERCHANGEABLE FILTER OR. SIEVE - Google Patents

Description

description

The invention relates to a filter or sieve station for liquid or gaseous flowing through a line system Media with exchangeable filter or sieve.

Especially when liquid and gaseous media are supplied to the processing station through a line system The medium is usually filtered again immediately before the processing station in order to impair the processing To remove or remove foreign substances but also residues or excretions (flocculation and the like) from the medium hold back.

For this purpose, a filter or sieve has been provided so far in the line releasably associated mouthpiece, which at intervals must be replaced. To do this, the supply line must be shut off. Located between the stopcock and the mouthpiece Medium still occurs when the mouthpiece is removed to replace or clean the filter or sieve the end.

The invention is based, in particular, on the problem of preventing the medium from escaping when the filter or the filter is replaced. to prevent the sieve.

The task is carried out with a filter or sieve station for liquid or gaseous media flowing through a line system solved with a replaceable filter or sieve, the invention consists of a multi-way valve housing to be inserted into the pipe system with two aligned nozzles, to which a plug releasably receiving the filter or the sieve is assigned with a smooth passage.

The plug, which forms part of the housing of the multi-way valve and has a smooth passage, is used for replacement or cleaning of the insert is transferred into the closed position, the smooth passage containing the insert then being perpendicular to the aligned connections of the pipe system in the alignment of the third or the third and fourth connection of the multi-way valve housing extends, whereupon the insert located in the plug through the now with the plug passage removed from the aligned socket and inserted a new or cleaned filter or sieve insert into the chick can be, which is then transferred back to the open position.

Since the line for changing the insert is shut off immediately before the use, there is no longer any undesired occurrence Leakage of medium in the line. A separate shut-off device is not necessary. Also need to Replacing the insert, no more parts are loosened. The replacement can thus practically under operating conditions take place.

Appropriately, the insert sits with a collar on one Ring shoulder in the passage of the chick. The insert can also be a cartridge.

The intended purpose is already achieved with the housing of a three-way valve. In particular then one becomes by default the direction of rotation of the plug ensure that when the tap is closed, the replacement position of the chick is controlled.

The explanation of the invention on the basis of the known construction element '-Multi-way valve "excludes custom-made products not enough for such a station. The construction principle of the multi-way valve is retained nonetheless.

The transitions from sieve to pilter stations are fluid. The invention extends to the full scope of Filtering and sieving.

The station can be used for both open and closed systems, for example for dispensing points, spray guns and the like as well as for cooling, flushing, lubrication circuits and the same.

In the drawing, the invention is based on an embodiment shown in a very schematic manner further explained. Show it:

Figure 1 the new screening station in section,

FIG. 2 shows a representation corresponding to FIG. 1, the chick in the replacement position.

According to FIG. 1, a screening station is inserted into the line 11, 12 through which the flow is directed in the direction of arrow A.

The screening station is formed by a housing 21 of a three-way valve which is connected to the aligned connecting pieces 211 and is connected to the lines 11, 12. Part of the three-way valve is a plug 22 with a smooth passage 221,

ill that the sieve cartridge 31 is inserted. It supports itself the sieve cartridge 31 with a collar 311 on a ring shoulder 222 in the passage 221 of the plug 21.

To replace the sieve cartridge 31, the plug 22 in the direction of arrow B in FIG. 2 changes to that shown in FIG Position transferred, with the passage 221 aligned with the third connection piece 213 of the tap housing 21, through which then the replacement of the sieve cartridge 31 takes place (double arrow C).
