Abstract
An improved valve is disclosed. In the preferred and illustrated embodiment, the valve utilizes a flat disk within a valve body, the disk supporting a peripheral groove having bearings therein for alignment and to enable rotation, and further includes pressure balanced opposing faces and receives a valve seat therein. The flat disk and body arrangement reduces the size of a large valve and reduces the wear occurring on the valve seat and seal mechanism. Alternate embodiments and configurations are disclosed.
Claims10
A rotary disk valve which comprises:
- (a) a hollow valve body having a at least one cavity therein with a smooth planar wall;
- (b) at least one flat circular valve disk supported in said cavity for rotary movement therein and in operative sealing engagement with said smooth planar wall, said flat valve disk having a pair of smooth parallel faces and having an opening therethrough asymmetrically positioned for rotation about the center of said disk;
- (c) said valve body having an inlet and an outlet with a passage therebetween passing through said cavity interrupted by said flat valve disk;
- (d) said valve disk being rotatable between a first position having the wall of said disk interrupting said passage and a second position having said disk opening aligned with said passage,
- (e) a removable valve sleeve insert slidably positioned in said flat valve disk opening adapted to be removed therefrom;
- and
- (f) spring means biasing said valve sleeve insert into operative sealing engagement with the smooth planar wall of said cavity, whereby said disk closes said passageway in said first position and opens said passageway in said second position.
