Abstract

A sliding plate is located across a pipe body to form a sliding plate valve having two positions: a through position and a flush position. In the through position, material flows through the pipe body. In the flush position, the flow of material is diverted so it goes out a side opening in the pipe body. An opening in the sliding plate permits material to pass through the plate only when the valve is in the through position, not when the valve is in the flush position. A side cut-out section of the body is attached to the sliding plate so that the section blocks the side opening when the valve is in the through position, but not when the valve is in the flush position.

Claims

1. A sliding plate valve having a through position and a flush position, the valve comprising:

(a) a pipe body having a side opening;

(b) a sliding flat plate located across the pipe body, the sliding plate having an opening located in the plate such that material can pass through the opening in the plate when the valve is in the through position, but material cannot pass through the opening in the plate when the valve is in the flush position; and

(c) a side cut-out section of the body attached to the sliding plate and located on the sliding plate such that the side cut-out section blocks the side opening when the valve is in the through position, but the side cut-out section does not block the side opening when the valve is in the flush position.

2. A valve according to claim 1 wherein the side opening of the body is formed from a cut of the body.

3. A valve according to claim 2 wherein the cut of the body is angular.

4. A valve according to claim 1 wherein the side cut-out section further comprises a sealing strip.

5. A valve according to claim 1 further comprising a locking means that is capable of locking the valve in the through position.

6. A valve according to claim 5 wherein the locking means is a lever locking means.

7. A valve according to claim 1 further comprising a locking means that is capable of locking the valve in the flush position.

8. A valve according to claim 7 wherein the locking means is a lever locking means.
