摘要： A reversible valve ball assembly for use in a down-hole pump oil field check valve. The reversible valve ball can be removed, inverted and reinserted into the check valve to provide a new valve ball sealing surface. The reversal of the valve ball is performed after the original valve ball sealing surface has worn and deteriorated so that it can no longer seat properly to form a seal between the valve ball surface and a valve seat. The valve seat is also reversible. A set of irregularly shaped valve ball guide arms are provided which rotate within valve guide apertures to provide a cleaning action between the valve guide apertures and valve ball arms to prevent accumulation of debris which tends to immobilize the reciprocating valve ball. An elongated gas-breaker fin is provided and can be used to prevent gas lock. The gas-breaker fin enables a reduced vertical length for the valve ball arms so that a reversible symmetric valve ball assembly can be utilized. The gas-breaker fin enables manufacture of a pump using closer valve spacing thereby reducing the compression chamber volume and increasing the compression in the pump chamber, to reduce gas lock and increase durability of the apparatus.
