Definitions

  • the invention relates to an insert according to the preamble of claim 1 and 17 and a drain system according to the preamble of claim 23 and 29.
  • the known from DE 2522424 A insert with water level-dependent odor trap function is removably positioned in the drainage system in the drain tank on a side wall having a drain pipe in a holding structure formed there.
  • the insert is interchangeable with another insert with odor trap and backflow stop function, but requires relatively high height due to the required odor trap height. It provides the insert no security against insects coming from below, which climb out through the grate at the top of the drain tank or the attachment used in the drain tank.
  • the water level-dependent odor trap function is lost when it dries out, which easily happens during long inflow breaks, especially in warm climates.
  • an inlet funnel is fixedly installed in a masonry drainage channel, which defines a horizontal sealing seat on the underside, and on which a collecting bowl flap is pivotally mounted.
  • the collecting tray flap is loaded by a weight in the closing direction against the sealing seat via a lever arm, begins a predetermined filling volume, which finally moves the collecting tray flap so that it pivots in a train in the full open position, the inlet of waste water through the Inlet funnel allows, and automatically returns to the closed position automatically after drying of the inlet and emptying of the filling volume.
  • drainage systems should also fulfill a fire protection function.
  • the drainage system should prevent the escape of hot and significantly escalating fumes via the odor-trap function until a fire-protective measure, triggered by the temperature, intervenes and then isolate the strand.
  • fire protection inserts are integrated into the drainage system, which consist of a swelling or expanding under the action of temperature material that shuts off the drainage system in the expanded state.
  • an annular fire protection insert is clamped on the outside of the drain pipe socket of the drain tank, which constricts the expansion pipe socket and blocks during expansion.
  • the fire protection insert is mounted inside the drain pipe socket of the drain tank so that it seals the drain pipe socket in case of fire directly inside.
  • the known drainage systems contain, as inserts, water-dependent odor traps in which a water trap is provided with a specific odor trap height. In case of fire, the combustion gases first push out the water in the odor trap upwards, or evaporate it, so that the combustion gases are pushed upwards until finally the fire protection insert becomes effective. Therefore, there is a need for an insert or drainage system, in the case of fire, the escape of fumes until the effectiveness of the fire protection insert is relatively reliably prevented.
  • the invention has for its object to provide a low-build, easily removable and usable insert for at least one drain tank exhibiting drainage system, and a drainage system, the simplest handling among other insect-security and optionally provides a wide range of different functions, e.g. also a reliable fire protection.
  • the insert part takes up the functional principle of the Klenk flap, but with such a low overall height that it can subsequently be easily used in existing drainage systems (retrofitting) or can be fitted as new equipment in new drainage systems without significant changes to the proven system concept.
  • the low height is achieved in that the evasion dome in the inlet funnel allows the movement of the weight of the collecting bowl flap, so that the inlet funnel can be shallow and the collecting bowl flap can be arranged at a small distance from the top of the inlet funnel.
  • the inserted insert not only provides a trap and anti-reflux function, but also provides protection against climbing insects.
  • the combination of the sealing seat with the flap and the combined with the sealing seat fire protection charge works great in case of fire, since the flap reliably mechanically shuts off and with increasing fire gas pressure from below even more firmly pressed until the fire protection charge expands and shuts off.
  • the fire protection charge operate, so to speak, as an additional drive and Absperrmedium for the flap, because it flanking the pressure of the combustion gases presses the flap to the sealing seat and keeps firmly pressed until complete foreclosure and embeds it, so to speak.
  • the insert Since in the drainage system, the insert is secured in position only by axial impressions in the direction of the open top of the drain tank or the attachment part in the sealing position, it can be easily inserted and removed again at any time, e.g. For cleaning work, where he also allows the use of other inserts in the drain tank because of the overhead position and allows an optimal low height of the drainage system, i. a height, as has prevailed in proven drainage systems in modern design relatively thin ceilings or floors.
  • the drainage system does not require any significant preparation for the insert because it is adapted to the conditions in drainage systems.
  • the fire protection charge is conveniently accommodated in the installation space provided by the design of the combination of sealing seat and flap.
  • the flap exerts its kickback and odor trap function so that hardly any combustion gases escape upwards.
  • the fire protection charge is placed so that it acts first as a drive, the flap brings reliable in the shut-off position and holds, so to speak, blocked in the shut-off, and then seals off the entire cross-section.
  • the insert part has at least one circumferential sealing frame on the outer edge, with which the insert part is secured in position in the sealing position substantially without any other auxiliary means. Namely, it is inserted into a correspondingly shaped or, in the case of many drainage systems, already existing shaft section of the drainage container or of the attachment part.
  • the sealing frame should have a relation to the outer edge outwardly projecting sealing structure in order to compensate not only for manufacturing tolerances thanks to the elasticity, but also to allow the use of the insert in differently sized shaft sections of different drainage systems each with the required tightness. Due to the outwardly occurring sealing structure Namely, enough meat of the elastic material of the sealing frame is provided between the rigid outer edge and the rigid wall in the manhole section to achieve the said compensating effect.
  • the sealing frame itself has a support flange projecting outwardly beyond the outer edge.
  • the insert is placed with the support flange on the one hand sealing and on the other hand positioning on a shoulder of the drain tank or the attachment part.
  • a sufficient sealing effect is achieved.
  • other measures may provide for secure positioning, e.g. the weight of an overlying grate or other component of the drainage system.
  • the outer edge itself has an over the sealing structure outwardly projecting support flange which is positioned on the rigid shoulder of the drain tank or the attachment part, wherein the underlying sealing frame performs the sealing function.
