Abstract
The invention relates to a slide valve (20) having a slide valve plate (32) movable in a slide valve rail (29) between a locked position and an open position in a slide valve casing (26), said slide valve rail (29) being provided with a slide valve seal for attaining a gas-proof locked position, said slide valve rail (29) being connected to the slide valve casing (26) via a flange connection in such a manner that the slide valve rail (29) is removable from the slide valve casing (26) radially to a flow axis of the slide valve (20).
Claims20
A slide valve (20, 25) having a slide valve plate (32, 63) movable in a slide valve rail (29, 67) between a locked position and an open position in a slide valve casing (26, 78), said slide valve rail (29, 67) being provided with a slide valve seal for attaining a gas-proof locked position, characterized in that the slide valve rail (29, 67) is connected to the slide valve casing (26, 78) via a flange connection in such a manner that the slide valve rail (29, 67) is removable from the slide valve casing (26, 78) radially to a flow axis (60, 95) of the slide valve (20, 25) so that the slide valve casing (26, 78) may remain in place while the slide valve seal is exchanged, wherein the slide valve rail (29, 67) has two rail halves (30, 31;
- 68, 69), each including a seal element (33, 34;
- 70, 71) for sealing against a slide valve plate surface (45, 46) to form the slide valve seal, wherein the rail halves (30, 31) are removable from the slide valve casing (26) independently of each other.
A slide valve (20, 25) having a slide valve plate (32, 63) movable in a slide valve rail (29, 67) between a locked position and an open position in a slide valve casing (26, 78), said slide valve rail (29, 67) being provided with a slide valve seal for attaining a gas-proof locked position, characterized in that the slide valve rail (29, 67) is connected to the slide valve casing (26, 78) via a flange connection in such a manner that the slide valve rail (29, 67) is removable from the slide valve casing (26, 78) radially to a flow axis (60, 95) of the slide valve (20, 25) so that the slide valve casing (26, 78) may remain in place while the slide valve seal is exchanged, wherein the slide valve rail (29, 67) has two rail halves (30, 31;
- 68, 69), each including a seal element (33, 34;
- 70, 71) for sealing against a slide valve plate surface (45, 46) to form the slide valve seal, wherein that the rail halves (30, 31;
- 68, 69) each comprise an axial support device (47, 48) for supporting against the slide valve plate surfaces (45, 46) on both sides.
A slide valve (20, 25) having a slide valve plate (32, 63) movable in a slide valve rail (29, 67) between a locked position and an open position in a slide valve casing (26, 78), said slide valve rail (29, 67) being provided with a slide valve seal for attaining a gas-proof locked position, characterized in that the slide valve rail (29, 67) is connected to the slide valve casing (26, 78) via a flange connection in such a manner that the slide valve rail (29, 67) is removable from the slide valve casing (26, 78) radially to a flow axis (60, 95) of the slide valve (20, 25) so that the slide valve casing (26, 78) may remain in place while the slide valve seal is exchanged, wherein the slide valve rail (29, 67) has two rail halves (30, 31;
- 68, 69), each including a seal element (33, 34;
- 70, 71) for sealing against a slide valve plate surface (45, 46) to form the slide valve seal, wherein at a casing connection side, the rail halves (30, 31;
- 68, 69) have a circular flange (49, 50;
- 83, 84) for forming the flange connection as a clamp connection (51, 52;
- 79, 80) using a circular flange (53, 54;
- 81, 82) formed at a casing part (27, 28;
- 76, 77) of the slide valve casing (26, 78).
