Definitions

  • the invention relates to a check valve for an indirectly controlled solenoid valve for a vacuum toilet according to the preamble of claim 1 .
  • valves which are connected to the normal water supply, for example in a household, wherein the occurring pressure ensures that the valve closes itself, i.e. locks the device located behind it against the water pressure from the water supply.
  • the locking part of said valve may be opened so that water can flow through it.
  • the valve will automatically return to the closed position. This is the usual requirement for example for a household washing machine.
  • a simple remedy for the indirectly controlled solenoid valves shall be provided by the present invention, which makes it possible to ensure in case of pressure surges that these pressure surges or a pressure build-up in general can not open the series valve under any circumstances.
  • the inven- tion thus provides for a check valve according to claim 1 .
  • the solution according to the invention consists in that a so-called indirectly controlled solenoid valve, a kind of check valve, is provided behind the shut-off valve.
  • a so-called indirectly controlled solenoid valve a kind of check valve
  • the non-return flap of the check valve assumes the opened position, which can be achieved in the easiest way by placing a tongue-shaped part in a kind of rubber ring out of the barrier position against the walls of the tubular housing of the valve, such that liquid can flow through.
  • the check valve part consists mainly of a rubber ring, out of which a tongue-shaped part or a flap is formed by a punching process.
  • the punching does not achieve a complete 360°, but leaves a bridge between the flap and the surrounding ring part in a range of 30° to 60°, such that the root part of the flap serves as a hinge, to enable a transfer of the flap to a locking position at a valve seat or to an open position, respectively.
  • Fig. 1 shows a longitudinal cross section through a check valve according to the invention
  • Fig. 2 shows a plane view of the non-return flap according to the invention.
  • connection piece 10 In Fig. 1 and Fig. 2 the part of a connection piece of a solenoid valve (not shown) is indicated by reference numeral 10. This is a connection piece, which faces away from the approach flow side.
  • a double sleeve 1 1 is provided on, advantageously screwed onto the connection piece 10.
  • a counter plate 14 having a passage 1 3 and abutting with the connection piece 10 is arranged inside the double sleeve 1 1 .
  • the counter plate consists of metal or a different somewhat flexible plastic material. Starting from the outside the counter plate 1 4 arches towards the passage 13, such that a conical projection 1 5 is formed.
  • a non-return flap 1 2 of flexible material advantageously of rubber or a flexible plastic.
  • the non- return flap 1 2 and the counter plate 1 4 are locked closely adjacent inside the double sleeve 1 1 through a screw coupling.
  • the non-return flap 1 2 may consist of a rubber disc, out of which a circular area, not extending over 360°, however, has been punched out. In Fig. 2 this area of the non-return flap 1 2 is hatched for illustration purposes.
  • the non-return flap 1 e.g. in the form of a rubber disc, is formed with a passage inside it, in which in turn a supporting plate 1 6 is received.
  • the supporting plate consists of two conical parts extending away from each other and a cylindrical part, wherein it is possible, to insert said supporting plate 1 6 due to the elasticity of the non-return flap 1 2 into the passage of the non-return flap 1 2.
  • the conical projection 1 5 effects that the non-return flap 1 2 is not to be seen in the completely sealed position, although it is the pressureless state.
  • This construction is preferred, because a low-flow resistance can be obtained this way, namely when the non-return plate shall be transferred into the opened position.
  • the non-return flap 1 2 deforms so that the supporting plate 1 6 abuts at the top against the walls of the screwing piece and the liquid can flow in unhindered.

Abstract

L'invention concerne un clapet de non-retour destiné à une vanne électromagnétique commandée indirectement, elle-même destinée à une toilette à aspiration. Pour éviter un fonctionnement défectueux pendant les changements de pression, un manchon double (11) est disposé sur une pièce de connexion (10) de la vanne électromagnétique. Un battant de non-retour (12) en matériau flexible est disposé à l'intérieur de cette pièce de connexion et forme un ensemble de non-retour avec une contreplaque (14) pourvue d'un passage (13).
