Sliding disk valve for pneumatic conveyance of abrasive material
First Claim
1. A linear actuated disk valve for a fluid conveyance system comprising:
- a valve body having an internal chamber and a passage through the valve body, the valve body having opposite ends with external connectors that continue the passage and that are connectable to other components in the fluid conveyance system;
a displaceable closure member in the chamber of the valve body, the closure member having a disk retainer assembly with a disk retainer and at least one circular closure disk engageable with the disk retainer, wherein the valve body includes an internal circular opening with a lip having a seating surface around the passage, and the disk has a perimeter rim with a seating surface contactable with the seating surface of the lip to seal the passage, wherein the engagement of the disk with the retainer is formed by a cam structure on the retainer and a cam tracking surface on the disk, the disk being laterally displaced on initial linear displacement of the disk retainer, and wherein the retainer assembly has a connector member constructed to connect with a reciprocal linear displacement actuator that linearly displaces the disk between a closed position with the disk located over the lip of the opening in the valve body that seals the passage, and an open position with the disk displaced from the opening in the valve body that opens the passage.

Abstract
A linear actuated disk valve for a fluid conveyance system constructed with a valve body having an internal chamber and a passage through the valve body, the valve body having opposite ends with external connectors that continue the passage and that are connectable to other components in the fluid conveyance system, the improvements being a displaceable cam action closure member in the chamber of the valve body, the closure member having a disk retainer assembly with a disk retainer and at least a pair of circular closure disks engageable with the disk retainer formed by a cam on the retainer and a cam track on the disk being laterally displaced on initial linear displacement of disk retainer with the disk retainer being connected to an actuator shaft with an improved sealing assembly for sealing the shaft at the top of the valve body.
