Ball and seat-type valve for downhole rod pump

The plunger of the valve has a ball of reduced diameter, so that it is inwardly spaced from the ribs of the cage. The plunger is centralized and guided by top and bottom stems attached to the ball and working in apertured webs carried by the cage and seat member. The cage has 3 ribs only, so that th...

Beschreibung
Zusammenfassung:	The plunger of the valve has a ball of reduced diameter, so that it is inwardly spaced from the ribs of the cage. The plunger is centralized and guided by top and bottom stems attached to the ball and working in apertured webs carried by the cage and seat member. The cage has 3 ribs only, so that the windows are wider. As a result of these features the areas of the flow passage through the valve are increased. The stems are straight-sided and the web openings are circular so fluid may flush out solids packing between the stems and webs. The valve has been improved to increase flow capacity.
