  • FLUID INJECTION SYSTEM
    Publication number: 20110162738
    Abstract: The present invention is directed toward an apparatus for efficient, durable, reliable, and cost-effective fluid injection. In particular, the present invention provides an unpowered device for automatic fluid injection dictated by pressure differential in the line. More specifically, the present invention provides a device for injecting a degreasing chemical into air relief valves in municipal wastewater systems, which operates off of the differential pressure in the pumped lines resulting from the pump operating cycles.
    Type: Application
    Filed: March 11, 2011
    Publication date: July 7, 2011
    Inventors: CARL KUHNLE, DAVID MONTEITH, Robert E. WALLACE
  • Method and apparatus for fluid pressure testing
    Patent number: 7950266
    Abstract: A method and apparatus for testing the functionality of automatic air valves positioned at high points of a pipeline system are provided. The invention generally provides a testing flange and a process for performing various fluid pressure tests to determine whether automatic air valves are properly releasing and/or stabilizing air within a pipeline system.
    Type: Grant
    Filed: January 14, 2008
    Date of Patent: May 31, 2011
    Assignee: The Wallace Group, Inc.
