Description

1 86003

This invention relates to a plastic manhole connector for a branch pipe to be attached to the side of a manhole or pipe, the manhole connector comprising an external sealing sleeve to be fitted in a standard size hole in the wall of the manhole or pipe and two fastenings extending in opposite directions from the outer jacket.

Previously known well connectors are only suitable for one-size branch pipe. As a result, there must be a separate connector size for each put dimension, which makes stock maintenance very cumbersome.

15

It is an object of the present invention to overcome this drawback by means of a well connector known from a transverse wall enclosing the flow opening of the well connector and from concentric connecting sleeves extending alternately in opposite directions. The well connector according to the invention is thus adjustably adjustable for branch pipes of different sizes.

Thanks to the invention, it is only necessary to keep in stock:. two or three special well connectors, all sizes, · *. to allow the connection of branch pipes.

Other features of the invention appear from the appended claims 2-4.

The invention will now be described in more detail with reference to the accompanying drawing, in which FIG. 1 shows an example of a well connector according to the invention as seen from the direction of the branch pipe, and FIG. 2 shows a side view of the well connector according to Fig. 1 and a partial section.

A plastic well connector according to the invention for connecting a branch pipe to a hole 2 made in the side of a well 1 or pipe can be fastened to the wall of the well 1 or pipe, for example by means of fastening screws or bolts. The well connector 10 has an external sealing sleeve 3 suitable for a standard size hole 2 made in the side of the well 1 and several easily removable sleeves 4 are arranged concentrically inside it, by means of which the well connector can be adjusted to accommodate standard pipes of different sizes than standard 15 holes. in order to accommodate as many sleeves 4 as possible in the same well connector, they can advantageously be arranged so that every other sleeve 4 protrudes from the cross wall 5 away from the well 1 and every other sleeve 4 towards the well 1, preferably so that the sealing sleeve 3 is closest to the sleeve 4 extends away from the well 1.

In order to achieve a sufficient sealing effect, the sleeves 3 and 4 of the well connector are somewhat conically tapered in the direction of the well 1 or the pipe to which the well connector is attached.

In line with the inner wall 30 of each sleeve 3, 4 of the well connector, the cross wall 5 has an annular cutting groove 6. When connecting the branch pipe to the well connector, the cross wall 5 is cut open along the cutting groove 6 located inside the sleeve 4 to which the branch pipe can be sealed. In this case, the part of the cross wall 5 inside this cutting groove 6-35a and the associated smaller-diameter sleeves are removed from the well connector.

3 86003

In order to fasten the well connector to the well 1 or the like, the well connector is provided with two fastening flaps 7 projecting in opposite directions from the sealing sleeve 3 of the well connector, mainly in the plane of the cross wall 5.

The fastening flaps 7 preferably have reinforced screw holes 8 for fastening screws or the like. In order to be able to attach the well connector to wells or main pipes of different sizes, the fastening flaps 7 are preferably at least partially of flexible material. According to one embodiment, the fastening flaps 7 have a flexible area in the vicinity of the sealing sleeve 3.

Claims (4)
