DESCRIPTION OF THE PREFERRED EMBODIMENTS
The present invention is blocking elements for ball trap screens that enhance the movement of the cleaning ball through the ball trap in a closed fluid flow system.
The principles and operation of blocking elements for ball trap screens according to the present invention may be better understood with reference to the drawings and the accompanying description.
Referring now to the drawings, Figure 1 illustrates a transparent view of a "T" type ball trap 2 having a ball trap housing 10 with a water inlet opening
12, a water outlet 13 and a ball trap extension lOe. Also shown is a ball trap screen 10' deployed inside the ball trap housing 10. It is understood that in such ball traps, the main fluid flow path is between water inlet opening 12, a water outlet 13 and that the cleaning balls are directed into the ball trap extension by means of a minor fluid flow path.
As mentioned above, the present inventors sought a solution to the problem of fluid flow patterns in the "T" type ball traps currently in use causing some of the cleaning balls to congregate in regions of the ball trap screen such that the cleaning balls are not drawn out of the ball trap into the ball collection chamber. The present invention is the solution to that problem.
The ball trap screen 10' is configured with a cone shaped inlet 12' that tapers inward and connects to a first screen section 10' a of the ball trap screen 10'. The first screen section 10'a extends from the inlet to an elbow with a second screen section IQ'b of the ball trap screen extending from the elbow 14 into the ball trap extension lOe that serves to connect the first 10' a and second 10'b screen sections. The ball trap screen 10' illustrated here is configured with a 90° elbow 14.
The present inventors have found that by deploying solid blocking elements on at least a portion of the cone shaped inlet 12' and on the 90° elbow 14 as illustrated in the drawings, the fluid flow patterns within the ball trap are changed sufficiently enough that the cleaning balls are directed to regions of the ball trap screen such that the cleaning balls are drawn out of the ball trap into the ball collection chamber.
While the drawings herein are intended as illustrations of a preferred embodiment of the ball trap screen blocking elements of the present invention, it will be readily understood that the size, shape and exact placement of the blocking elements on the ball trap screen may be varied within the scope of the present invention.
That said, the present inventors have found that the preferred placement of the cone blocking element 50 is on the region opposite the 90° extension 16. Preferably, but not necessarily, the cone blocking element 50 is configured to cover thirty percent of the circumference of the cone shaped inlet.
As illustrated herein at least a portion of the 90° elbow 14 includes a substantially planer solid area 14a configured at substantially 45° to both the first 10' a and second lO'b screen sections. It will be readily understood that substantially planer solid area 14a also lies at substantially 45° to the fluid flow path between water inlet opening 12 and water outlet 13 of the ball trap housing 10. The present inventors have found that extending the solid area surrounding area 14a further enhances the fluid flow patterns within the ball trap so as to better direct the cleaning balls to regions of the ball trap screen such that the cleaning balls are drawn out of the ball trap into the ball collection chamber. To that end, blocking elements 52 and 54 are deployed the first 10'a and second lO'b screen sections respectively so as to substantially circumscribe solid area 14a.
It should be noted that an innovation of the present invention is a method of enhancing the movement of the cleaning ball through the ball trap of
in a closed fluid flow system, once fluid flow is initiated, by blocking portions of the ball trap screen so as to modify the fluid flow through the ball trap.
A further innovation of the present invention is the deployment of the biocking elements on the ball trap screen. It should be noted that each of the blocking elements are individually formed and such deployment may be done at the time of fabrication of the ball trap screen. Alternatively, the blocking elements may be configured integrally with the screen. That is, the screen itself may be fabricated with solid areas such that upon fabrication of the ball trap screen element, the location of the solid portions of the screen material correspond to the preferred locations of blocking elements 50, 52 and 54.
It will be appreciated that blocking elements by be fabricated independently for installation as aftermarket components for use in retro -fitting existing ball traps used in closed fluid flow systems.
It will be appreciated that the above descriptions are intended only to serve as examples and that many other embodiments are possible within the spirit and the scope of the present invention.
