Title: Innovations by John N Scapes

Introduction

John N Scapes is a notable inventor based in Schaumburg, IL (US). He has made significant contributions to the field of valve technology, holding a total of six patents. His innovative designs focus on enhancing the functionality and reliability of valves used in various applications.

Latest Patents

One of his latest patents is for an external valve operating means. This invention forms a seal around the rotating valve stem of a valve operating under internal pressure. The design prevents the escape of fluids should the valve's primary seals fail. The external valve operating means allows for the rotation of the valve stem without removal or compromise of the seal. A stationary operating seal cap is in threaded and sealed engagement with the valve body. Upon partial disengagement of the stationary operating seal cap, the pressure within the external valve operating means is vented. An external valve stem drive protrudes through the top of the stationary operating seal cap, with an O-ring forming a seal between the two. The bottom of the external stem drive mates with the rotating valve stem while the top is shaped for gripping by a tool. This design ensures that the rotation of the external stem drive via the tool effectively rotates the valve stem while maintaining the surrounding seal.

Another significant patent by Scapes is the stem seal configuration for ball valves. This invention addresses the issue of O-rings in ball valves used in refrigeration systems, which can fail when exposed to new EPA-correct refrigerants and blends. The quarter turn ball valve features a valve stem seal configuration that protects the O-ring from contact with the refrigerant fluid. The design includes a valve stem receiving passageway with annular recesses, where a primary seal washer and an O-ring are seated. The configuration minimizes wear by maintaining the O-ring in a state of 'controlled squeeze,' ensuring it is subjected only to radial compression.
