Abstract

A fluid flow control valve utilizes a ball which is rotated about an axis greater than 0 degrees and less than 90 degrees to the direction of fluid flow. The ball member utilizes a fluid flow conduit through its center with a flat surface disposed at an angle to the fluid flow conduit. When in the closed position, the flat surface is disposed flush with a valve face on one port of the valve. The ball is also disposed so that its center is less than a radius length from the surface defined by the valve face.

Claims

1. A valve for controlling the flow of fluid through an opening in a barrier wall comprising

means defining a valve body comprising

means defining spaced first and second parts, said parts having a central axis, said body including a valve face defining an imaginary geometric surface generally flush with the surface of said barrier wall, and generally perpendicular to said central axis, said second port passing through said barrier wall,

a flow control member disposed between said first and second ports comprising

a ball member having a center and means defining a conduit therethrough, said central axis being coincident with the axis of said conduit when said ball member is in the open position,

a seal bearing member adapted to hold said ball member between said first and second ports, with the center of said ball member located along said conduit axis such that the distance measured along said central axis of said parts from said geometric surface defined by said valve body face to said center of said ball member is less than the radius of said ball member when said ball member is in the closed position,

means defining a generally flat surface on said ball member, and

means for rotating said ball member between an open position in which said conduit in said ball is in fluid communication with said first port and said second port and a closed position in which said flat surface of said ball member is flush with said valve body face and said second port,

said means for rotating said ball member having an axis of rotation bisecting the angle defined by the intersection of the axis of said conduit through said ball member and the axis perpendicular to and passing through the center on said flat surface of said ball member.

2. The valve as claimed in claim 1 further comprising

means for draining fluid from said conduit through said ball member when said ball member is in the closed position.

3. The valve as claimed in claim 2 wherein said means for draining said conduit in said ball member comprises

a first drain port,

a second drain port,

a syphon connected to said second drain port having its opening proximate the lower portion of said conduit.
