Definitions

  • the invention relates to a pipe aerator for the final line ventilation of drinking water installations according to the preamble of claim 1.
  • End-of-pipe aerators which allow air to flow into the pipe system when there is a negative pressure in the pipe system, thereby interrupting the water column in the pipe system between the drinking water supply line and the tapping point and thereby preventing dirty water from being sucked back into the pipe system flowing water, but contain a housing connected to the pipe system at a suitable location with an air outlet opening leading into the free environment, which, when water enters the aerator housing at operating pressure, is closed by a floating body on the water and when a negative pressure occurs and a water level falling in the aerator housing is opened by the closing body.
  • the common end-strand pipe aerators contain a piston as a floatable closing body, which has on its circumference upper and lower fin-like guide webs, which guide the piston on the somewhat larger diameter wall of a vertically cylindrical aerator housing so that the piston without tilting in the aerator housing along it Center line can be raised or lowered.
  • the piston carries on its upper face a disc-shaped seal, which in the exactly coaxially raised closed position of the piston has a circular, the air passage opening surrounding sealing seat edge of the cap must cooperate absolutely watertight. It has been shown in practice that deposits and other contaminants from the water, which can always occur over time, impair the functional reliability of the aerator in the conventional tube aerators.
  • the object of the invention is to improve the functional reliability, to improve the production and the feasibility of maintenance and repair, and to make the design more compact in order to reduce the installation space requirement by further developing an end-strand pipe aerator of the type mentioned at the beginning.
  • the invention solves this problem by designing the tube aerator with the characterizing features of claim 1.
  • the pipe aerator according to the invention is described in more detail with reference to the drawing, in which an advantageous embodiment is shown in axial section.
  • the end-of-pipe aerator shown contains an essentially cylindrical upright aerator housing 1, which is connected with its lower end 2 to the end strand of a drinking water installation and the upper end of which is closed by a removable screw-on cap 3 which is screwed on in a sealing manner.
  • the closure cap 3 has a central air passage opening 4.
  • the air passage opening 4 is covered by a decorative hood 5 which is attached to the closure cap 3.
  • a guide cage 6 which can be easily pulled out again and is centered on the inside of the housing and is preferably made of a plastic, is inserted from above.
  • the lower end of the guide cage 6 sits on an inner housing step 7.
  • an annular disk 8 is clamped, which also rests on the upper end of the guide cage 6 and thereby fixes it in the vertical direction in the aerator housing 1.
  • a simple floatable ball 9 is arranged as the closing body of the tube aerator, the diameter of which is matched to the inside width of the guide cage 6 so that the ball 9 is guided in the guide cage 6 on a movement line lying in the vertical longitudinal center line of the aerator housing 1 .
  • the guide cage 6 has a stop 10, on which the ball 9 sits in the lowered position so that a connection remains free between the lower housing end 2 and the air passage opening 4.
  • a disc-shaped recess 11 is formed on the underside of the closure cap 3, into which a conventional O-ring seal 12 made of an elastic material is inserted, which forms the sealing seat of the tube aerator.
  • the O-ring seal 12 is centered by the disc-shaped recess 11 exactly to the longitudinal axis of the aerator housing 1 and exactly positioned in a cross-sectional plane of the aerator at right angles to the longitudinal axis.
  • the vertical depth of the recess 11 is matched to the thickness of the O-ring seal in such a way that the washer 8 rests on the upper side against the O-ring seal 12 and thereby fixes it in the recess 11.
  • the central opening 13 of the washer 8 is dimensioned in diameter so that the central opening 13 leaves a passage of the spherical top of the ball 9 until contact with the O-ring seal 12.
  • Guide cage 6 and ball 9 can be manufactured easily and cheaply, especially when using plastic.
  • the aerator housing 1 does not need to be laboriously cleaned inside in order to restore the unobstructed mobility of the floatable closing body and the functionality of the aerator, but only requires the guide cage 6 with a handle Ball 9 is pulled out of the aerator housing and replaced by a perfectly functioning new unit consisting of a guide cage and ball.
  • the guide cage directs the ball with increasing water column in the aerator in the longitudinal axis of the aerator housing in the sealing seat formed by the O-ring seal 12, so that the ball does not need any additional time to center in the sealing seat.
  • the closing process of the tube aerator is extremely quick and no water reliably escapes through the air passage opening 4.
  • the guide cage 6 directs the ball 9 down even centrally when the water column drops, so that the flow resistance of the tube aerator prescribed by the standard is repeatedly guaranteed.
  • the ball occupies a smaller space in the tube aerator than the piston of the usual end-tube aerator, so that the volume of the closed Pipe aerator remaining air is very low and the overall height of the tube aerator can be kept small overall.
