Reciprocating piston pump adjustable inlet ball travel

摘要

A ball stop valve ( 10 ) allows liquid to enter a reciprocating piston pump when internal suction is great enough to raise the ball ( 13 ) and create a space between the ball ( 13 ) and a seat ( 9 ). This invention allows the user to easily insert or remove rings ( 15 ) into the ball inlet valve, either above or below the ball ( 13 ), so that the space between the ball ( 13 ) and the seat ( 9 ) can be adjusted. The valve ( 10 ) is easily accessible to the user and all components of the ball valve ( 10 ) are removable.
