Title:
STEEL BALL VALVE FOR STEEL BALL DISSEMINATING DEVICE
Document Type and Number:
Japanese Patent JP2002206896
Kind Code:
A
Abstract:

To provide a steel ball valve which correctly operates always by eliminating such failure as friction, deformation, and biting of steel balls which occur at a gap part between a valve body for switching transportation direction of steel balls and a duct side wall.

A steel ball valve 1 which is provided, as a switching valve, to a duct intersection part between a steel ball supply duct 35 and a branch duct 35a comprises a plate-like valve body 2 for switching flow of steel balls and a sheathing board 5 erected on both sides of the valve body 2. The valve body 2 is rotated by a driving mechanism such as an air cylinder 49. The supply duct 35 is provided with right and left tilted side boards 3 and a tilted ceiling plate 4 for stopping down the flow of steel balls so that they flow into between the sheathing boards 5 on both sides of the valve body 2. A spacer which forms a gap between the sheathing boards 5 on both sides of the valve body 2 and a side wall of the duct intersection part is provided to prevent the steel balls from biting.
