Abstract

The invention is a component of a subsurface traveling barrel bottom anchor pump comprising a traveling valve assembly which includes: a cylindrical valve body having a lower section, the lower section having a central bore therethrough and external threads which interact with a threaded connection on a traveling barrel to removably attach the valve body to the traveling barrel; an upper section having a rod connection externally threaded for attachment to a pumping rod; a center section having a fishing neck portion and cage portion; a valve cage accommodated entirely within the internal portion of the cage portion; a valve ball positioned within the valve cage; a valve seat abutting the valve cage; and a ball and seat plug threaded into the lower section of the valve body for retaining the valve seat in the valve body.

Claims

1. In a subsurface traveling barrel, bottom anchor pump for pumping fluid from an oil and gas reservoir, the improvement comprising a traveling valve assembly which includes:

a cylindrical valve body having a lower section, said lower section having a central bore therethrough and external threads which interact with a threaded connection on a traveling barrel to removably attach said valve body to said traveling barrel and adjacent internal threads;

an upper section having a rod connection externally threaded for attachment to a pumping rod, a center section having a fishing neck portion and a cage portion;

a valve cage accommodated entirely within the internal portion of said cage portion;

a valve ball positioned within said valve cage;

a valve seat abutting said valve care; and

a ball and seat plug threaded into said internal threads of the lower section of said valve body for retaining said valve seat in said valve.
