Abstract
In a slide valve, especially for coating installations, for fluidic separation of two modules or chambers, interconnected through an opening, containing at least one slide plate, integrated in a housing transfixed by said opening, and which may be bidirectionally moved between an inactive position, releasing said opening, and an operating position, completely covering said opening, and at least a closing drive, which may be activated to act upon said slide plate in its operating position and for its sealing contact in a closed position against a sealing surface transfixing said housing, according to the invention, at least one of said closing drives is firmly attached inside housing, relative to the activating movement of said slide plate.
Claims20
A slide valve, for separation of two subsequent modules or chambers, having separately adjustable pressure levels, wherein said modules are adapted for coating units, comprising:
- a housing;
- an opening transfixing said housing, having a cross-sectional area and a circumference;
- a slide plate, disposed within said housing, having an area greater than said cross-sectional area of said opening, said slide plate having a first side and a second side, and being bidirectionally moveable between an inactive position wherein said opening is completely uncovered, and an operating position wherein said opening is completely covered;
- a first sealing surface integrated within said housing for engaging said first side of said slide plate;
- a second sealing surface integrated within said housing for engaging said second side of said slide plate;
- a first closing drive integrated within said housing, disposed between said first sealing surface and said opening, and operable to engage said first surface of said slide plate in said operating position wherein said second surface of said slide plate is forced against said second sealing surface;
- a second closing drive integrated within said housing, disposed between said second sealing surface and said opening, and operable to engage said second surface of said slide plate in said operating position wherein said first surface of said slide plate is forced against said first sealing surface;
- wherein said first closing drive and second closing drive function in unison or independently from each other.
An installation for processing comprising at least two adjacent modules interconnected over a passage opening and at least a slide valve, operable for closing said opening, comprising:
- a housing;
- a slide plate, disposed within said housing, having an area greater than a cross-sectional area of said opening, said slide plate having a first side and a second side, and being bidirectionally moveable between an inactive position wherein said opening is completely uncovered, and an operating position wherein said opening is completely covered;
- a first sealing surface integrated within said housing for engaging said first side of said slide plate;
- a second sealing surface integrated within said housing, for engaging said second side of said slide plate;
- a first closing drive integrated within said housing, disposed between said first sealing surface and said opening, and operable to engage said first surface of said slide plate in said operating position wherein said second surface of said slide plate is forced against said second sealing surface;
- a second closing drive integrated within said housing, disposed between said second sealing surface and said opening, and operable to engage said second surface of said slide plate in said operating position wherein said first surface of said slide plate is forced against said first sealing surface;
- wherein said first closing drive and second closing drive function in unison or independently from each other.
