Definitions

  • the invention relates to a backflow safety valve for Exhaust systems with one as insertion into an exhaust pipe insertable valve carrier, one end face of a in its upper area hinged check valve wearing.
  • Boilers and other condensing boilers in which the Exhaust gases are discharged with excess pressure into the exhaust system need to be connected to a backflow preventer after the Be equipped exhaust system, if several such Condensing boilers to a common exhaust pipe are connected.
  • the return flow fuse ensures in the switched-off state, one of the condensing boilers no exhaust gases generated by the other condensing appliances the exhaust pipe and the switched-off condensing boiler through into the environment.
  • a rigid Non-return valve which in its upper area over a Hinge is hinged to the valve carrier.
  • This hinge or joint in which surfaces slide relative to each other can be moved in its function by the out of the Exhaust gas condensed condensate and similar Impurities are impaired in its function.
  • the object of the invention is therefore, a Backflow safety valve of the type mentioned so train that with simple construction and easier Mounting a safe function even under the influence of Condensate deposits is ensured.
  • non-return flap made of flexible Material may be on a separate joint or hinge be waived.
  • the deformability of the non-return valve itself forms the joint necessary for the valve function. Therefore, the connection with the valve carrier in very simpler and easier to assemble by a Latching done.
  • the mobile storage of Check valve thus has no sliding on each other or rubbing parts and is therefore not against Condensate deposits sensitive.
  • the support webs are at their the Non-return flap facing side with protruding nubs or projections provided. This becomes a flat Avoiding the non-return flap on the supporting webs, which lead to condensation in case of condensation could.
  • the flexible non-return flap at its edge a to Valve carrier towards projecting and frontally thereto has adjacent rib, which is also in this edge area a flat and therefore prone to stick concerns avoids.
  • FIG. 1 Backflow safety valve is in an exhaust pipe 1 of a Brennwertêts arranged, in Fig. 1 with dash-dotted lines is only hinted at.
  • the condensing boiler is connected; leads to the right the exhaust pipe to a common exhaust pipe string, are connected to the other condensing boilers. each the condensing boiler is by such Backflow safety valve against backflow of the exhaust gas secured.
  • the illustrated backflow safety valve has a sleeve-shaped valve carrier 2, which has a circumferential Seal 3 carries and as a slot in the exhaust pipe. 1 is used.
  • the right in Fig. 1 end face 4 of Valve carrier 2 is designed inclined. She has one Passage opening 5 for the exhaust gas.
  • This passage opening 5 is through a check valve 6 closed, the in Fig. 1 in its closed Position is shown.
  • the check valve 6 is made made of flexible material, such as rubber, and is close its upper edge by means of a latching connection 7 am Valve carrier 2 attached.
  • the Rastharm 7 two each with a thickened head. 8 provided latching pin 9, each in a detent opening 10 of the valve carrier 2 are engaged.
  • the closable with the flexible non-return valve 6 Passage opening 5 on the end face 4 of the valve carrier 2 has a plurality of support webs 11, which at their the Check valve 6 facing side with protruding Nubs 12 or projections are provided. At these pimples 12 comes the flexible non-return valve 6 in the closed Condition to the plant, so that a prone to sticking flat system is avoided.
  • the check valve 6 has at its edge a to Valve carrier 2 protruding and frontally thereto adjacent rib 13 on.
  • This rib 13 is also used a flat and therefore prone to sticking concerns to prevent.
  • the support webs 11 (at illustrated embodiment, three support webs 11) arranged parallel and at a distance from each other. she extend from an upper, the locking connection. 7 having surface piece 14 obliquely down to the bottom Area of the front side of the valve carrier. 2
  • the flexible Non-return valve 6 thus forms by their flexible Execution itself a joint or hinge for the Opening movement.
  • the embodiment shown in Fig. 3 differs from the embodiment according to the Fig. 1 and 2 only in that the flexible Non-return valve 6 stiffening ribs 15, which at the illustrated embodiment on the of Valve carrier 2 facing away from the outside 16 of the flexible Non-return valve 6 are formed.
