Abstract
Official abstract text for this publication.
The present invention concerns a valve ( 1 ), a valve closing body ( 14 ) and use of a valve ( 1 ) and a valve closing body ( 14 ) of the type used for injecting dry powder which is mixed with liquid, and where the dry powder is supplied under the liquid surface in a mixing vessel ( 11 ) in which a vacuum is typically maintained. The novel feature of a powder valve ( 1 ) according to the invention is that a closing body ( 14 ) of the valve in the closed position extends through the valve seat ( 13 ) of the valve and into the wet environment. It is hereby achieved that when the valve ( 1 ) is opened, powder or dust from powder is not deposited on the valve closing body ( 14 ). This is in spite of the valve closing body ( 14 ) being wet, due to contact with the liquid to which the powder is added. Due to its elongated shape, the valve closing body ( 14 ), which in the withdrawn position opens for inflow of powder, has the property that the inflowing powder dries the valve closing body ( 14 ) at first and keeps it dry subsequently.
First claim
Opening claim text (preview).
The invention claimed is: 1. A system for injecting dry powder into a wet environment, the system comprising: a mixing vessel containing liquid under vacuum conditions, the liquid having a liquid surface; and a valve connected to a powder feed pipe for feeding powder into the valve and connected to the mixing vessel at a level under the liquid surface, such that the valve is in contact with the liquid, and the valve, when open, connecting the powder feed pipe with the liquid for…
