Definitions

  • the invention relates to a Dopppe check valve for (independent) blocking the flow of gaseous and / or liquid media in pipes, hoses or the like, with a housing for installation in a media-carrying pipeline, wherein the housing has a flow channel, the flow-through cross section through two check valves closed is, wherein the two non-return valves are mounted on an axis arranged in the flow channel and can be brought to close the flow channel for sealing engagement with a seat of the valve, according to the preamble of claim 1.
  • valves are known in practice in numerous embodiments.
  • a valve from the house of the applicant is known for example from DE 0 2007 057 663 A1.
  • the invention is based on the object to further develop valves of the type mentioned.
  • a valve for achieving this object has the features of claim 1. It is therefore provided that the check valves mounted on the axle and the seat form an assembly, and that the assembly is detachably arranged in the valve, such that the assembly without disassembly in or out of the valve is on or removable.
  • the assembly is fastened by means of a ring nut in the housing, wherein the housing has an internal thread into which an external thread of the ring nut is screwed, and wherein the assembly by the ring nut sealingly pressed against a seat in the housing becomes.
  • the assembly has a flange, via which the assembly in the region of a seat in the housing can be fastened.
  • the housing has a media-tight sealable opening for the assembly through which the assembly can be inserted into or removed from the housing.
  • the opening is preferably a separate opening, that is to say in particular independent of an inflow opening and / or an outflow opening of the housing.
  • FIG. 1 is a perspective view of a first embodiment of a valve in partial representation
  • Fig. 2 is a vertical section through the valve along section line II - II in
  • Fig. 3 is a vertical section through the valve along section line III - III in
  • FIG. 5 shows a detail of FIG. 2 on an enlarged scale
  • FIG. 6 is a perspective view of a second embodiment of a valve
  • Fig. 7 is a vertical section through the valve of FIG. 6 along
  • Fig. 8 is a vertical section through the valve of FIG. 6 along
  • Fig. 9 is a horizontal section through the valve of FIG. 6 along
  • valve 10 is intended for installation in a pipeline, not shown.
  • the pipeline can be used to transport gaseous or liquid media. In practice, solids may also be transported together with the gaseous or liquid media.
  • the valve 10 has a housing 11.
  • the housing 11 may have flanges.
  • the housing 11 is penetrated by a flow channel 12 which extends through the housing 11, namely from an inflow opening 13 to an outflow opening 14.
  • the flow channel 12 is delimited by a circumferential wall 15 of the housing 11.
  • two check valves 16 are arranged, by means of which the flow of the medium can be stopped.
  • the two check valves 16 are mounted on bushings 17 on a central axis 18. About the bushings 17, the check valves 16 between a closed position in which they lock the flow and an open position pivoted.
  • a seat 19 for the check valves 16 is further formed.
  • the seat 19 is arranged as a separate, preferably ring-like member circumferentially on the wall 15 of the housing 11 and has a seat surface 20 against which the check valves 16 in the closed position.
  • a web 21 is arranged, which extends transversely through the flow channel 12.
  • a rear side of the web 21 also serves as a seat surface 20 for facing areas of the check valves 16.
  • flap springs 22 are provided which, as usual, press the check valves 16 into the closed position. The spring force of the flap springs 22 is dimensioned so that the spring force is overcome at a predetermined media pressure and the valve 10 and the two check valves 16 are opened.
  • the housing 1 1 has an upper-side opening 25, which is closed by a cover 26 media-tight.
  • the assembly 24 is preferably media-tight with the housing 1 1 and the walls 15 thereof connected.
  • the assembly 24 can be easily attached in the housing 1 1, for example, a fitter the assembly 24 detected and inserted through the opening 25 in the housing 1 1 and there festschraubt by means of the ring nut 30.
  • a seat 29 is provided for the assembly 24 in the walls 15, which is formed accordingly and against which the assembly 24 is pressed sealingly by the ring nut 30.
  • the orientation of the assembly 24 and the flap springs 22 in the housing 1 1 can be specified by means of a projection or pin 34 which is arranged eccentrically on the housing 1 1 and engages in a corresponding bore 35 or a corresponding blind hole in the assembly 24. In this way, the correct installation of the assembly 24 can be ensured.
  • the housing 1 1 and the walls 15 thereof are constructed so that no media can accumulate, for example in the form of puddles in recesses in the housing 11. In this way it can be prevented that when passing LNG (liquefied natural gas) deposited Liquids freeze and the valve 10 or individual components thereof are damaged.
  • the assembly 24 consists at least of the seat 19 and the two non-return valves 16. It is understood, however, that other components may belong to the assembly, such as the web 21, the flap springs 22 or the like.
  • the variant of the valve 10 shown in FIGS. 6 to 10 has essentially the same features or advantages as the valve 10 shown above and differs only with regard to the assembly of the assembly 24 in the housing 11.
  • the assembly 24 instead of a thread or a ring nut 30 has a circumferential flange 32, via which the assembly 24 is fastened by means of bolts 33 on the housing 11 or in the region of the corresponding peripheral seat 29.

Abstract

L'invention concerne une soupape antiretour double servant à bloquer le passage d'un fluide gazeux et/ou liquide dans des canalisations, tuyaux flexibles et similaires, comportant un carter (11) destiné à être monté dans une canalisation d'acheminement du fluide. Le carter (11) présente un canal de passage (12) dont la section transversale traversée par le fluide peut être fermée par deux clapets antiretour (16), les deux clapets antiretour (16) étant montés au niveau d'un axe (18) agencé dans le canal de passage (12) et pouvant être amenés en appui étanche sur un siège (19) de la soupape (11) pour fermer le canal de passage (12). L'invention est caractérisée en ce que les les clapets antiretour (16) montés au niveau de l'axe (18) et le siège (19) forment un ensemble (24), et en ce que l'ensemble (24) est agencé de manière amovible dans la soupape (11) de telle manière que l'ensemble (24) peut être monté dans la soupape (11) ou en être démonté.
