摘要:
A drain for the purpose of discharging, for instance, sewage water, industrial wastewater and/or surface water, which drain (10) is at least provided with a drainage channel (1) extending substantially in vertical direction, wherein the drain (10) is provided with a valve (3) comprising a floating body (4) which, under the influence of rising water, is movable from a release position to a closing position in order to close a respective drain passage (5), characterized in that, both in the closing position and the release position, the floating body (4) extends inside the said drainage channel (1). The invention further provides valve, evidently intended for such a drain (10).
摘要:
A device for shutting off or regulating a medium flow, such as, for instance, a shutoff or an overflow slide, provided with a sliding plate (2) which is movably set up and which is connected with an adjusting mechanism (3, 4, 5) by means of which the sliding plate (2) can be set in different positions, characterized in that the device is further provided with a mounting plate (7) in which a passage opening (8) is provided, of which passage opening (8) the passage area can be shut off or regulated with the sliding plate (2), while the mounting plate (7) further serves for guiding the sliding plate (2), and to that end the sliding plate (2) is U-shaped at two opposed, first longitudinal edges (2a, 2a'), the two U-shaped parts embracing the corresponding longitudinal edges (7a, 7a') of the mounting plate (7).
摘要:
An apparatus for controlling and/or closing a passage (6) in a watercourse, such as, for instance, a ditch, canal, conduit or pipe, which apparatus is provided with a plate (5) and a frame (2), the plate (5) and the frame (2) being connected with an adjusting element (16,26) which is drivable by a drive, for the purpose of adjusting the position of the plate (5) relative to the frame (2), the apparatus being further provided with at least one adjusting element (16,26) and with an aligning shaft (18) with two gear wheels (15), the distance between the gear wheels (15) substantially corresponding to the width of the plate (5), while further gear racks or chains (12) are provided which the gear wheels (15) engage, the aligning shaft (18) and the gear racks or chains (12) being coupled to the frame (2) and the plate (5), such that a displacement of the plate (5) on the right-hand side of the plate (5) results in a corresponding displacement of the left-hand side of the plate (5) and vice versa.
摘要:
An apparatus (1) for closing or controlling the passage area of a passage (19), such as for instance a valve or a weir gate, wherein the apparatus is provided with a sliding plate (3) which is adjustable from an opened position to a closed position and any positions therebetween, wherein the sliding plate (3) is slidable with respect to a frame (2), which frame (2) is mountable on a wall (W) or the like in which the passage (19) closable and/or controllable with the apparatus (1) is included, wherein the apparatus (1) is further provided with a driving facility for adjusting the sliding plate (3) with respect to the frame (2), wherein the driving facility comprises a screw spindle (6) which is, near a lower side thereof, rotatably bearing-mounted in a lower bearing block (9) which is, preferably, connected with the frame (2), wherein the sliding plate (3) is provided with a threaded block (10) provided with internal screw thread which is arranged for cooperation with the screw spindle (6).
