Definitions
- the invention relates to a check valve with a housing having a valve seat, a valve closure piece interacting with the valve seat and an upstream dirt trap, in particular for sanitary water fittings.
- check valves e.g. to prevent air from entering a supply line or sucking back liquid that has already passed through into a supply line in the event of negative pressure.
- check valves there is great interest in preventing water from flowing back into the supply line since the water may no longer be of food quality.
- check valves whose movable valve connecting piece is spring-loaded in the direction of a valve seat, which is formed in the housing of the check valve.
- the invention has for its object to eliminate this disadvantage and to create a check valve of the type mentioned, which can be manufactured at a relatively low cost, is easy to assemble and in particular ensures extremely safe functioning even after a long period of operation.
- the dirt trap is preferably formed in one piece with the housing. It is also advantageous if the dirt trap has a conical shape and its largest diameter is smaller than the outer diameter of the housing.
- the subject of the invention is shown in an exemplary embodiment, namely the figure shows a longitudinal section through a check valve according to the invention, which e.g. can be arranged in the supply lines to a sanitary mixer tap, e.g. within the connection point between the "S" connections and an Aüfputzmi battery.
