Abstract
A sluice gate comprises a frame (10) consisting of a flat plate (11) and a door (15) movable across an opening (13) between open and closed positions by means of a threaded rod (16) and hand wheel (17, Fig. 1). Wedge seats (21, 22) on the frame cooperate with wedges (23, 24) on the door to ensure a tight seal. At least some of the parts of the frame (10) and/or door (15) which are involved in the wedge action are of a semi-rigid material which is sufficiently resilient to become deformed by the wedge action in the closed position of the door (15). <IMAGE>
Description
SPECIFICATION
A sluice gate
THIS INVENTION relates to sluice gates of the kind comprising a frame defining an opening, and a sliding closure member mounted on the frame for movement across the latter to open and close the opening. Conventionally such devices are made from cast iron or steel and include at least one wedge and wedge seat arrangement to force the closure member into sealing contact with the frame around said opening as the closure member approaches the closed position. In such an arrangement at least one part is usually adjustable to compensate for inaccuracies in the casting method used to produce the article. The adjustable feature also serves to compensate for wear in use.Furthermore, the casting method of manufacture usually requires further treatment of the interacting surfaces of the article to ensure smooth movement of the closure member relative to the frame during opening and closing.
An object of the present invention is to provide an improved sluice gate which accordingly comprises a frame defining an opening, and a sliding closure member mounted on the frame for movement across the latter to open and close said opening, there being means attached to the closure member for moving same between open and closed positions, and at least one co-operating wedge and wedge seat arrangement to force the closure member into sealing contact with the frame over the opening therein as the closure member approaches said closed position, characterised in that at least a part of the frame or at least a part of the closure member is of a material sufficiently resilient to become deformed by the wedge action in said closed position.
Two embodiments of the invention will now be described, by way of example only, with reference to the accompanying drawings in which:
Fig. 1 is an upright view of a sluice gate made in accordance with the invention, with a door in its closed position;
Fig. 2 is a section taken on line ll-ll of Fig.
1;
Fig. 3 is a section taken on line Ill-Ill of Fig.
1;
Fig. 4 is a perspective fragmentary view showing the closure member at a position just removed from its closed position; and
Fig. 5 is a perspective view of a modified form of sluice gate made in accordance with the invention.
Referring now to the drawings, the sluice gate comprises a frame generally indicated at 10 which consists of a generally flat plate 11 having an integrally formed upright portion 12 extending generally peripherally around the frame to provide rigidity therefor, and an opening 13 (visible in Fig. 3) in the central lower region of the frame 10 and defined peripherally by a rigid sealing ring 14.
A closure member or door 15 is slidably engaged within the upstanding portion 12 of frame 10 and is moved between open and closed positions with respect to opening 13, in the conventional way by means of a threaded spindle 16 and hand wheel 17. Conventionally, the door 15 may rise relative to spindle 16, or alternatively the door and spindle may rise relative to a bearing member 18 on the frame.
The frame 10 and door 15 are produced from a semi-rigid material such as a polymer or resin and preferably by an injection or a cold-pour moulding method using a pre-formed mould of, for example, glass reinforced plastics. The mould itself can be produced by forming around a wooden model or alternatively around an existing cast iron or steel sluice gate.
During production of the frame 10, the sealing ring 14 is integrally moulded therewith, or if preferred, bonded thereto, and, if required, a co-operating sealing surface can be inset into or bonded to the face of door 15 which preferably is produced by a similar moulding technique using a similar semi-rigid material.
As can be seen clearly from Fig. 4, there is provided in each side edge region of the frame 10 and extending transversely across the upstanding portion 12 thereof a pair of reinforcing ribs 20 which overhang plate 11 within upstanding portion 12 to present a pair of tapered wedge seats 21 and 22. Corresponding wedges 23 and 24 respectively are integrally moulded on the face of the door 1 5 remote from its sealing face. A further overhanging wedge seat 25 is provided at the base of the frame and corresponds with a further integral wedge 26 at the base of the door.
It will be seen that as the door approaches its closed position during operation, wedges 23, 24 and 26 engage their corresponding wedge seats and, owing to the slightly deformable nature of the material from which the frame and its integral wedge seats are formed, a firm sealing pressure is applied by the wedge action to force the door into sealing contact with the ring 14.
Referring now to Fig. 5, in larger size sluice gates, additional wedge seats 30 and 3 1 may be provided adjacent the base of the frame with corresponding wedges, one of which can be seen at 32 on the door 15a. In this embodiment a lip 33 may be provided in the upper arcuate region of sealing ring 14a, and engaged by corresponding hooks or wedge seats 35 attached to or integrally moulded with the door. In Fig. 5, the door is shown in an exploded view to illustrate the various parts adapted to ensure a tight sealing fit between the door and the sealing ring.
In the embodiments illustrated in Figs. 1 to 4 and Fig. 5 respectively, the frame plate 11, 1 1a includes a number of apertures 40 to receive fastening devices such as bolts or studs for attachment to a wall or pipe end. Alternatively, threaded studs may be integrally moulded with the frame.
A sluice gate produced in accordance with the invention is simple and inexpensive to produce, has good corrosion resistance when compared with metal equivalents and requires little or no surface treatment after moulding, and thus provides a number of clear advantages when compared with its conventional counterpart produced from cast iron or steel.
Indeed, its weight is approximately 1/5th of that of a similar sluice gate made from steel.
Whilst some of the wedge seats such as those illustrated at 30 and 31 in Fig. 5 may be bolted to the frame for easy removal for cleaning or replacement, it is generally unnecessary for the wedges or the wedge seats to be movably attached to their respective parts for adjustment, since a tight seal is ensured by the wedge action assisted by slight deformation of the co-operating parts of the frame and/or of the door.
Although the device has been described as being produced almost completely from a semi-rigid material, it is essential only that at least some of the co-operating parts involved in the wedge action be so constructed. The remainder can be of a-rigid material such as cast iron or steel.
