SLIDE VALVE FOR A HOPPER CONTAINING POWDERED MATERIAL OR MATERIAL WITH A SMALL GRAIN SIZE
First Claim
1. A slide valve (101) for a powdered material or a material with a small grain size;
- said valve comprising a stiff frame (10), which defines a discharge mouth (OP) to discharge the material, and a shutter (40), which is activated by respective moving organs (45), said shutter (40) being mobile and having an extension that is such as to shut, in plan view, said discharge mouth (OP);
said valve being characterised in that it comprises, furthermore, a height adjusting device (20) for a sealing element (30), said height adjusting device (20) being suited to compensate the loss of sealing effect between the lower face (80) of said sealing element (30) and an upper face (40A) of said shutter (40), said loss of sealing power being due to the wear generated by the relative friction between said lower face (80) of said sealing element (30) and said upper face (40A) of said shutter (40).

Abstract
A slide valve for a powdered material or a material with a small grain size. The valve comprises a stiff frame, which defines a discharge mouth to discharge the material, and a shutter of the discharge mouth, which is activated by respective moving organs. The valve is characterised in that it comprises a height adjusting device for a sealing element. The height adjusting device is suited to compensate the loss of sealing effect between the lower face of the sealing element and an upper surface of the shutter. The loss of sealing power is due to the wear generated by the relative friction between the lower face and the surface.
