ABSTRACT:
A ball valve type injector and catcher apparatus is formed of a valve body with a generally spherical internal cavity and a diametrical bore defining an axial flow passage therethrough. A generally spherical valve member in the valve body rotates about an axis perpendicular to the axis of the flow passage. A diametrical bore of the valve member has an axis perpendicular to the pivot axis thereof. A ball entry and removal passage is perpendicular to the diametrical bore of the rotatable spherical valve member. A doll cap seals off the ball entry and removal passage. A retainer carried within the diametrical bore of the rotatable valve member captures a paraffin cutting ball. A bypass fluid passage within the valve body opens at opposite ends. A knockout rod projectable into the interior of the diametrical bore of the rotatable valve member mechanically drives the paraffin cutting ball through the ball entry and removal passage after removal of the doll cap. A drain passage to the valve cavity permits draining of accumulated liquid escaping through seals to the valve body cavity. An adjustable needle valve permits the bypass passage to be completely closed off.
