Description

Collection container for separated pieces of water

The invention relates to a collecting container for separated water fractions according to the preamble of claim Is

For devices for processing compressed air and similar media or the like, the water contained in the gaseous media must be separated and emptied from time to time, common constructions apart from a collecting vessel generally require four parts, namely a part mostly made of brass, which is inside pushed through the bottom wall of the collecting container, screwed from the outside with a brass nut and with a relatively large O-ring is sealed against the collecting container, as well as a fourth part in the form of a drainage screw, which is against an inclined surface of the first mentioned brass part seals. This means that there are two sealing points, on the one hand the static seal between the brass part and Collecting container and, on the other hand, the seal to be loosened during emptying between the emptying screw, which is preferably made of plastic and a part made of brass. It is also disadvantageous that I. there is only a single sealing surface between brass and plastic, | which in the event of scratches or other damage does not guarantee a reliable seal in the long term. In addition, this construction is on- | reason de ** relatively large number of parts expensive.

The object of the invention is therefore to provide a collecting container according to the upper I

concept of claim 1 to create, both in relation to the We- f

method of sealing and emptying is improved, as well as with we- %

niger parts. F.

This object is achieved according to the characterizing part of claim 1 I. I.

Further refinements of the invention can be found in the description below and to be found in the subclaims.

The present invention will be illustrated with reference to the accompanying figure, FIG shows detail and section of a collecting container, described.

The illustrated collecting container 3, also called "bell", only has two further parts, an emptying screw 1, preferably made of plastic, and a flexible sealing element 2, preferably one O-ring. The bottom of the collecting container 3 has an opening with a stepped sealing seat with a flat and a cylindrical sealing surface 4 or 5 and a stepped thread offset from the sealing seat. the The drain screw 1 is stepped accordingly, the sealing element 2 being clamped between the stepped sealing seat and the stepped drain screw 1. Due to the graduated design of the sealing surfaces 4 and 5 on the collecting container 3 and 6 and 7 on the drain screw 1, a double sealing effect is achieved. Not just each of them seal planar sealing surfaces 4 and 6, but also the cylindrical sealing surfaces 5 and 7.

So should one of the sealing surfaces no longer seal properly or should dirt particles temporarily impair the sealing function, the second sealing surface is still available Disposal. In this way, the sealing effect is guaranteed for a longer period of time and with greater security.

To make the drain screw captive, it has one elongated approach 8 which protrudes into the collecting container 3. The approach 8 is designed to be compressible by a longitudinal slot 12. Farther has the approach 8 at the point 9 is greater than that Bore 10 of the collecting container 3. By a bevel 11 at the free end of the projection 8, however, together with the flexibility due to the Slit 12 achieved easy insertion of the drain screw 1, but falling out due to the larger dimension of the cam-shaped End and prevented by its plane there, that is, surface perpendicular to the axis.

Furthermore, it is desirable that when emptying the water, which is contaminated with dirt particles, does not pass through the thread, at least not to a large extent *

For this purpose, the drain screw has 1 below the sealing ring 2, but above the thread a transverse bore 13, which is in connection with an axial bore 14 attached underneath and open to the outside stands. In this way it is achieved that when draining the water this for the most part axially through the bore 14 downwards escapes and does not splash out of the threads in an uncontrolled manner, so that the deposition of dirt particles in the thread is largely prevented.

In order to make this emptying as resistance-free as possible, the approach is 8 of the drain screw 1 in the area of the bore 10 of a significantly smaller diameter than this *

Finally, there is another major economic benefit except to mention the reduction from four to two parts. If you have all the different collection containers 3, which are for a certain range of applications come into question, standardized in the area of the seal and the thread, a single type of drainage screw 1 is sufficient to to equip all collecting containers with it and accordingly less Having to keep parts in stock.
