Abstract
A valve for a reciprocating compressor having a valve seat with a plurality of flow channels which open into an end face of the valve seat; a valve plate having a planar sealing surface which is designed to control the flow channels of the valve seat and has passage openings which are spatially offset relative to the flow channels of the valve seat, at least one projection being arranged on the end face of the valve seat, which projection projects into a passage opening of the valve plate at least in a closed valve state.
Claims13
A valve for a piston compressor, comprising
- a valve seat with a plurality of flow channels that open into an end face of the valve seat;
- a valve plate having a planar sealing surface which is designed to control the flow channels of the valve seat;
- wherein the valve plate extends in a plane parallel to the end face of the valve seat, is arranged concentrically to the valve seat and has passage openings which are spatially offset relative to the flow channels of the valve seat,
- wherein
- at least one projection is arranged on the end face of the valve seat which, at least in a closed valve state, projects into a passage opening of the valve plate, wherein the at least one projection is designed as a part that can be inserted into the valve seat and removed from the valve seat, the at least one projection is made of plastic, and the valve seat is made of metal.
A method of operating a valve for a reciprocating compressor, the valve comprising a valve seat and a valve plate,
- wherein the valve seat has a plurality of flow channels and an end face into which the flow channels open, and the valve plate has passage openings which are spatially offset relative to the flow channels of the valve seat,
- wherein in a closed valve state the valve plate blocks the flow channels and releases them in an open valve state, and wherein the valve plate assumes the open state when it automatically lifts off the valve seat due to a fluid pressure applied to the valve, so that fluid flows through the flow channels of the valve seat and downstream through the passage openings of the valve plate,
- wherein
- fluid is directed via at least one projection, arranged on the valve plate of the valve seat, into a passage opening of the valve plate, wherein the at least one projection is designed as a part that can be inserted into the valve seat and removed from the valve seat, the at least one projection is made of plastic, and the valve seat is made of metal.
