Definitions

  • the invention relates to a, preferably made of plastic, non-return valve for a, preferably also made of plastic, exhaust pipe of a combustion device according to the preamble of claim 1, in particular for a heating burner, preferably for a gas burner (condensing boiler), with a valve seat, a valve seat associated, a guide portion having float and with a condensate collecting channel for collecting the exhaust pipe downwardly draining condensate.
  • a backflow valve for an exhaust pipe is known in which a float is arranged in the region of a flow constriction, guided radially inwardly directed guide webs. These narrow the free flow cross-section, which is perceived as disadvantageous.
  • a guide portion of the float is rod-shaped and closely enclosed by the guide webs, the radially inner guide surfaces are radially spaced from the peripheral surface of the flow constriction.
  • the known backflow preventer is directly part of the exhaust pipe forming pipe section and difficult to clean in the event of contamination.
  • the float is not removable.
  • the DE 100 37 967 C1 describes a non-return valve, in which the float or its guide rod is closely entwined by a guide tube which is held at radially inwardly narrowing the free flow cross-section rods.
  • the known backflow lock is not optimally cleanable.
  • a complex constructed backflow valve which comprises a two-part, telescopically extendable float, both floating body parts are guided in a central guide opening, which is held by radial webs.
  • the guide surface for guiding the floating body is formed by the inner periphery of the aforementioned guide opening and is provided on a built-in part.
  • the floats are guided exclusively on the installation part. It is felt to be disadvantageous that the free flow cross-section is narrowed by the radial webs and the central guide surface defining the guide opening.
  • the present invention seeks to provide a comprehensive a float backflow lock for an exhaust pipe, which is characterized by a good cleanability.
  • the backflow valve should provide a maximized flow area and, moreover, tilting should be avoided.
  • valve seat is formed on a built-in, releasably releasably with fixing means on a guide surface for guiding the Guide portion of the float having, releasably secured by the fitting part holding part and / or fixed.
  • the invention is based on the idea that the sealing function, i. the valve seat, and the guiding function, i. the at least one guide surface for cooperation with the guide portion of the float to be at least partially separated by the valve seat and at least one guide surface for the float are arranged on different components, namely the valve seat on a mounting part and the guide surface on a holding part, according to the invention built-in and holding part via fixing means form-fitting fixed to each other and / or fixed, thereby in turn to ensure easy disassembly and thus good cleanability. Due to the component separation of the two functions, it is in fact possible to disassemble the return flow lock manually after a certain installation or operating time in order to expose the guide surfaces and the valve seat and clean in this way.
  • the fixing means are designed as a bayonet closure or a bayonet closure, so that fitting and holding part by a combined Aufsteck- and rotational movement axially secured to each other or secured, in particular latched, are.
  • a valve seat diameter is preferably larger than a guide diameter of the guide surface.
  • the condensate collecting channel for collecting the condensate flowing down the exhaust pipe is part of the holding part, whereby even more preferably the condensate collecting channel is arranged radially adjacent and radially outside the guide surface for guiding the guide section of the floating body.
  • At least one axial stop for limiting the lifting movement of the float is formed in development of the invention on the insert, wherein the axial stop is preferably designed and arranged such that the float is held on the insert , Float and built-in component are preferably removable from the holding part with dissolved fixing means or removable. It is particularly expedient if the float, for example, by appropriate compression or elastic deformation, is removable from the mounting part to allow a further improvement of the cleanability.
  • the fixing means comprise a bayonet lock, and the mounting part and holding part by relative rotation to each other can be fixed and released again.
  • corresponding recesses are in the holding part, so that the built-in part can be inserted axially into the holding part, so that corresponding radial extensions engage in the recesses and then a fixation can be made by relative turning.
  • the condensate collecting channel is designed as a siphon, that is a condensate water column Preventing penetration of exhaust gases upstream through the exhaust gas passage prevented.
  • the formation of the condensate collecting channel as a siphon has the additional advantage that it can be dispensed with a separate from the backflow, to the condensate collecting channel via a line, in particular a hose connected siphon, as must be used in the prior art, when the siphon Even with closed backflow valve, ie even when resting on the valve seat float, a pipe region in the exhaust flow before the float with a pipe portion in the exhaust flow behind the float condensate conductively connects that so from the top into the condensate collecting water flowing water through the siphon into an area behind the valve seat, ie in the exhaust gas flow direction in front of the valve seat, can pass, then further in the direction of the burner, if necessary, a condensate collecting tray provided there can penetrate.
  • the insert axially projects into the condensate collecting channel and subdivided in principle into at least two mutually communicating tubes and communicating ring sections, wherein preferably a fluid-conducting connection of an inner ring section, in particular is arranged above the aforementioned axial gap, to a region in the exhaust gas flow direction in front of the valve seat below an inlet height for condensate in the outer ring portion, in particular such that it is ensured that flooding of the valve seat with condensate is reliably avoided.
  • the backflow lock not as in the prior art itself forms the actual exhaust pipe and is directly connected to exhaust pipes, but if further education the backflow valve, in particular the holding part, is axially inserted into an exhaust pipe and in the radial direction opposite this, in particular by means of an outer peripheral ring seal, preferably an O-ring is sealable.
  • the design of the return flow block, as an insert allows a universal arrangement and beyond a cleaning of the backflow valve is further facilitated by removal from the exhaust pipe.
  • the holding part in particular the end, an annular collar for abutment on an exhaust pipe end face or for radial engagement in a optionally provided inner groove of an exhaust pipe.
  • At least one axial stop for limiting the axial stroke movement of the insert part is provided Float is provided. It is particularly useful, if for this at least one axial stop a lateral recess in the guide portion of the float is provided through which the axial stop can reach.
  • the guide portion of the floating body preferably guided exclusively by its outer circumference comprises a plurality of, in particular uniform, circumferentially spaced axial webs, wherein recesses are provided between the axial webs, which on the one hand can serve to reach through axial stops and which, moreover, have the purpose of reducing the weight of the Float to reduce to ensure that even in operating conditions low power of a burner and thus a low gas pressure opening is ensured.
  • the axial webs form at their, more preferably curved, outer circumferential surface réellesabschnits vom for cooperation with the at least one guide surface of the holding part. Also can flow through the recesses exhaust with the backflow lock open radially outward and then further up.
  • the float has a convexly curved in the exhaust gas flow direction cover portion, which can be provided centrically indentation, which further increases the stability.
  • bits 7 is a preferred embodiment of a backflow valve for an exhaust pipe partially cut and shown in different operating states (open or closed).
  • the non-return valve consists of three main components, each of which is designed as a separate plastic injection molded part.
