Abstract

Control valve for controlling the flow of material, the valve including a body with an inlet and an outlet, a disc mounted in the body for closing and opening the valve, the disc mounted on a guide which is secured to the body, the guide mounted on a support, and slots extending through the guide and support for the flow of material therethrough. The valve is particularly useful for controlling the flow of erosive and corrosive material.

Claims

1. A valve, the valve having

body means,

the body means having

inlet means,

outlet means, and

disc means,

the disc means disposed within the body means and movable to close off or open the valve,

the disc means movably mounted on guide means, the guide means secured to the interior of the body means,

the guide means having slot means therethrough for conducting through the guide means material falling thereon, and

the guide means mounted on shelf means for supporting and mounting the guide means, the shelf means mountable to the valve body means and having shelf slot means disposed so that material flowing through the guide slot means then flows into and through the shelf slot means.

2. The valve of claim 1 wherein the guide means has recess means therealong for receiving material deposited on the guide means.

3. The valve of claim 2 wherein the slot means extend from the recess means to the bottom of the guide means.

4. The valve of claim 1 wherein the guide means is a continuous integral single member.

5. The valve of claim 1 wherein the portions of the guide means which come into contact with the disc means are protected with hardfacing material on those portions.

6. The valve of claim 1 wherein the shelf means is a continuous integral single member.

7. The valve of claim 1 wherein the guide means are mounted to the shelf means by an indexing tang connected to and extending downwardly from the guide means, the indexing tang receivable and received within a tang recess formed in the shelf means.

8. The valve of claim 7 wherein the guide means is mounted to the shelf means solely by the indexing tang.

9. The valve of claim 1 wherein the body means is lined with refractory material.

10. a valve, the valve having

body means,

the body means having

inlet means,

outlet means, and

disc means,

the disc means disposed within the body means and movable to close off or open the valve,

the disc means movably mounted on guide means, the guide means secured to the interior of the body means,

the guide means having guide slot means therethrough extending from the recess means to the bottom of the guide means for conducting through the guide means material falling thereon, the guide means having recess means therealong for receiving material deposited on the guide means, the guide means mounted on shelf means for supporting and mounting the guide means, the shelf means mounted on the body means and having shelf slot means therethrough and disposed so that material flowing through the guide slot means flows into and through the shelf slot means.

11. A guide means for guiding a gate means in a valve, the valve having body means, the body means having inlet means, outlet means and the disc means, the gate means disposed within the body means and movable to close off or open the valve, the gate means movably mounted on the guide means, the guide means comprising,

guide member means secured to the interior of the body means, the gate means movably disposed on the guide member means,

the guide member means having guide slot means therethrough for receiving and transmitting beyond the guide means material deposited thereon, and

the guide means mounted on shelf means for supporting and mounting the guide means, the shelf means mountable to the valve body means and having shelf slot means disposed so that material flowing through the guide slot means then flows into and through the shelf slot means.

12. The guide means of claim 11 wherein the guide member means has recess means therealong for receiving the material, the guide slot means communicating with the recess means.

13. The guide means of claim 11 wherein the guide member means is a continuous integral single member.

14. The guide means of claim 11 wherein the portions of the guide member means which are contacted by the gate means are protected with hardfacing material.

15. A guide means for guiding a gate means in a valve, the valve having body means, the body means having inlet means, outlet means, and disc means, the gate means disposed within the body means and movable to close off or open the valve, the gate means movably mounted on the guide means, the guide means comprising,

guide member means secured to the interior of the body means, the gate means movably disposed on the guide member means, the guide member means having recess means therealong for receiving the material,

the guide member means having guide slot means therethrough for receiving and transmitting beyond the guide means material deposited thereon, the guide slot means communicating with the recess means, and

the guide means mounted on shelf means for supporting and mounting the guide means, the shelf means mountable to the valve body means and having shelf slot means disposed so that material flowing through the guide slot means then flows into and through the shelf slot means.
