The invention relates to a drive means for a slide valve having two parallel spindles (10) which are driven in rotation by at least one motor (11), travelling nuts (12) which engage the spindles (10) and are movable in the longitudinal direction of the spindles by rotation of the spindles (10), and a cross-yoke (13) which is arranged transversely with respect to the spindles (10) and is connected to the travelling nuts (12) on the one hand and to a rod (14) on the other hand, which rod is arranged in parallel between the spindles (10) and is connected or connectible to a slide plate, the rod (14) being axially movable by the motor (11) for the actuation of the slide plate. It is distinguished by the fact that the travelling nuts (12) and the rod (14) are each articulatedly connected to the cross-yoke (13).

HOT-AIR TUYERE STOCK FOR A SHAFT FURNACE, IN PARTICULAR A BLAST FURNACE
A hot-air tuyere stock for a shaft furnace, in particular a blast furnace, consisting of at least two, in particular three, refractory-lined tube sections (10, 11, 12) with a movable connection (15), wherein each movable connection is formed as a spherical joint and comprises a compensator (16) which is similar to a corrugated-tube. The spherical-joint-type connection (15) comprises a bayonet locking mechanism (17), the complementary locking surfaces of which are each spherical segment areas (18, 19 and 20, 21) of which the centre point is the swivel point (D) of the spherical-joint-type connection (15).
The invention relates to a shutoff device for high-temperature gaseous media, in particular for cutting off the hot gas lines leading from recuperators to a blast furnace, comprising a housing having sealing seats cooled by a coolant, and a shutoff organ displaceably disposed in the housing, also cooled by a coolant, wherein except for the housing sealing seats and the sealing surfaces on the shutoff organ, all surfaces coming into contact with the hot gas have a fireproof, at least partially two-layer or multi-layer cladding, wherein lines carrying the coolant comprise at least in sections a surface and/or surface structure preventing deposits. The invention further relates to a method for producing such a shutoff device.
A double-disc gate valve is provided, the shut-off or valve discs of which are displaceable from an open position into a closed position and vice versa by means of an actuator rod, there being associated with the actuator rod a locking device by means of which the valve discs, together with the actuator rod, are fixable in the closed position. The locking device is movable in the longitudinal direction of the actuator rod relative thereto from an unlocking position into a locking position and vice versa, the locking position being variable in dependence upon the closed position of the valve with predetermined maximum pressing force of the valve discs against the associated valve housing sealing seats.

The invention relates to a slide valve, especially for regulating a catalyser flow or similar high temperature media, said valve comprising a tubular section (10) and a diaphragm (11) which is arranged therein and comprises an inlet and an outlet (12a, 12b) through which a medium flows during operation. Said valve also comprises a slide plate (13) which interacts with the outlet (12b) in order to regulate the catalyst flow and can be displaced into an open or closed position I, II. The slide plate (13) is displaceably mounted by means of meshed guiding elements (14, 15) arranged on the tube side and on the plate side. The invention is characterised in that the tube-side guiding elements (14) are arranged upstream of the outlet (12b) in the flow direction.

A double-disk slide valve (10), the shut-off plates (16, 17) of which are displaceable by means of an actuator rod (21) and which is provided with a bridging pipe (22) having two sealing rings (23, 24) that are in operative engagement with corresponding housing sealing seats (14, 15) of the slide valve housing (11) when the slide valve is in the open position. At least one of the two housing sealing seats (14, 15) rests, by the action of a resilient element (25), under predetermined pressure against the sealing ring(s) (23, 24) associated with the bridging pipe (22) when the slide valve is in the open position and against the peripheral edge of the shut-off plate(s) (16, 17) when the slide valve is in the closed position.
