Definitions
- the present invention relates to the field of hydraulic techniques and can be used for the closure of waterways in dams and piers or for the regulation of the water level in basins and rivers.
- WO 2007000508 discloses an adjustable automatic valve moving between states respectively open and closed and comprising for this a body that can rotate about a horizontal axis, the body having:
- At least one filling port allowing a water supply to fill the tank and at least one emptying port) of the tank, and a counterweight below said axis, in the closed state of the valve.
- a problem to be solved is to have the power structure (intake, water / filling port) so as not to (or less than in the solution of WO 2007000508) interfere with the stability of the body , in closed positions as open.
- a proposed solution consists in that the aforementioned valve comprises a first pipe distinct from the body, connected to the filling orifice, and having a water intake located higher than the filling orifice, that the valve is open or closed. This will confer optimized hydraulic efficiency and increased stability and greater capacity for discharging floating bodies.
- the first pipe and has an end connected to the filling port of the tank, and therefore an independent end of the body, the water intake, corresponding to an increased level of filling. That is, the tank fills when the water level reaches and / or exceeds that level of filling raised relative to the level of the filling port formed in the body of the valve.
- the first pipe can be disconnectable of the filling orifice, by movement of the body.
- the first pipe is connected to the filling orifice when the valve is closed and is disconnected when the valve is open, by pivoting the body
- the valve comprises a second pipe distinct from the body, connected to the filling orifice when the valve is open and which is disconnected when the valve is closed by pivoting the body, the second pipe then having a water intake located lower than the water intake of the first pipe.
- the valve comprises a second pipe separate from the body, connected to the first pipe and connected, by a common section of the first and second pipes, to the filling orifice, permanently, that the valve is closed or open, the second pipe having a water intake located lower than the intake of the first pipe.
- the second pipe can be connected to the first pipe so that the filling port is supplied with water only after water supply of the first pipe.
- the second pipe having a water intake located lower than the intake of the first pipe, this first pipe can define, downstream of the intake of the first pipe , a siphon supplying water to the filling orifice).
- the common section of the first and second pipes can be at least locally deformable to follow the pivoting of the body) about said horizontal axis.
- at least one of the pipes is provided with a water level adjustment means above which the tank fills.
- the fixing orifice (s) filling / pipe (s) is sometimes heavy and / or bulky. It is therefore preferable to limit the change of pipe to change the level of filling.
- the water intake will have a level adjustment means, which can be housed in a stack or other remote structure, and the level of the water intake will be independent of the level of the basin.
- a structure such as a dam may comprise two walls Bajoyer (lateral retaining walls) and one or more intermediate stacks. In the case of a channel, a stack will designate the support wall on a bank.
- the water level adjustment means may be as a nozzle coming to be positioned on the filling end of the pipe.
- the tip can come to slip on the pipe and form, by contact, a sealed connection.
- the tip may have an orifice corresponding to the water intake.
- the water intake of the first pipe, when the valve is closed is located higher than the filling orifice and higher than the body of the valve in the closed position.
- the valve when the valve is open, in comparison with the prior art, the raising of the water intake relative to the position of the filling orifice when the body is horizontal allows a stop of the filling of the tank then the water level in the upstream basin is higher.
- the valve closes while the water reserves in the basin are larger.
- the water intake of the second pipe may be located higher than the filling orifice and that the body, open valve.
- the first pipe is preferably attached to a fixed support member other than the body.
- the first pipe is removably attached to a fixed support member other than the body which it will be removable.
- drain holes are also called drains or purges.
- at least one drain hole is formed at the bottom of the tank to ensure complete emptying of the tank.
- the body of the valve will have an inclination relative to the vertical when the valve is in the closed position.
- the body will be said in the vertical position, and when the valve is in the open position, the body is said to be in a horizontal position.
- the position of the axis of rotation and the inclination of the body of the valve will preferably be chosen so as to minimize the amounts of counterweight necessary to maintain the valve in the closed position and the maximum spill before tilting, namely the maximum water level that covers the valve but does not generate its opening.
- a hydraulic structure comprising an adjustable automatic valve having all or some of the aforementioned characteristics, and a fixed support member, other than the body, to which the first pipe is fixed.
- the support member may comprise at least one stack or other fixed structural element, such as a wall wall of the structure, or a side wall of a channel.
- the body of the valve can: be housed between two batteries; its axis can then be housed in the piles just as it can also be fixed on studs. be mounted directly on studs across a threshold.
- the water level adjusting means may comprise a plate comprising a hole.
- connection between the first pipe and the filling orifice will preferably be direct, that is to say that the filling orifice will be a hole to which the first pipe will be connected, with, if necessary, an intermediate element, serving for example seal, or extending out of the tank filling port.
- an intermediate element serving for example seal, or extending out of the tank filling port.
- a fastener will connect the first pipe to an element other than the body of the valve, for example a stack of a structure in which the valve would be installed.
- the filling orifice will be located in a lateral face of the body of the valve. Such a positioning makes it possible to isolate the basin filling orifice and to avoid any accidental feeding of the tank. In addition, it is then possible to position the pipe out of the flow. The pipe is thus less eroded by the current.
- the second pipe it will preferably have a water intake located at a lower rating than the water intake of the first conduct.
- the first and second pipes are provided with a water level adjustment means above which the tank fills, for the same reasons as above.
- the counterweight holds the valve in the closed position, that is to say the body in a vertical position.
- the valve behaves like a bulkhead. Water is retained upstream.
- the water For levels between the peak and a first level (high level), located above the peak, the water pours overflowing over the body of the valve. The intake of the first pipe will thus correspond to the "high level".
- the tank fills.
- the filling of the tank combined with the hydrostatic and dynamic forces, causes the valve to tilt, which is then in the open position.
- the minimum volume of the tank is calculated so that once filled via the first pipe, it triggers the rotation of the body from its vertical position to horizontal. Once tilted, the flow above the body and the water in the tank hold the body in its horizontal position.
- the reservoir is then fed through the second pipe until the level has dropped below a second level (low level).
- the presence of the first pipe and allows to fill the tank, and thus open the valve, for large floods during which the overflow is not enough to restore the desired water level.
- the second pipe then has an end which receives water through the tank filling orifice, valve open, and a filling end corresponding to an enhanced drain level, also called “low level” (its grip of water, located higher as the filling port, valve open.
- an enhanced drain level also called “low level” (its grip of water, located higher as the filling port, valve open.
- the tank continues to fill up when the water level reaches and / or exceeds this increased drain level.
- the filling end of this second pipe corresponds to the "low level”.
- the reservoir As the water level does not fall below the low level, the reservoir is saturated and the valve remains open. Once the water level below the low level, the tank gradually empties, then the body of the valve is recovering and the valve closes.
- the presence of the second pipe stops the filling of the tank while the water level is higher.
- the reserves of water carried out before a flood are thus not lost following a flood.
- the counterweight will be dimensioned so as to bring the body of the valve in a vertical position while the reservoir is empty but the flow still exerts efforts on the body of the valve. So, substantially the passage of the body of the flat position towards the erect position will not be brutal.
- the valve When the water level reaches or exceeds the high level (water intake of the first pipe) while the valve is in the closed position, it will preferably overflow over the body of the valve, and the tank fills with its orifice opening into the first pipe. Once the tank is filled, the valve will swing open and remain substantially flat, allowing the water to drain. The filling port will then supply the second pipe, and the tank will continue to be fed until the water level reaches or exceeds the low level (water intake of the second pipe). As the water level drops below the low level, the tank will empty while the flow will continue over the body of the valve. Once the tank emptied, the valve will close, by the counterweight.
- the high level water intake of the first pipe
- the first pipe will be at least partially integrated in the support structure, such as a battery, so that its end forming the water intake will then be further upstream. Thus, as long as the upstream water level exceeds the intake of the first pipe, the reservoir will be fed.
- the filling orifice of the reservoir may be formed in a lateral face of the body.
- the valve may be dimensioned such that at the time of tilting of the valve the level in the reservoir remains below the filling orifice. It is then preferable that the filling orifice is formed at the top of the tank. The water losses in the reservoir are thus limited during rotation of the panel.
- the filling orifice is in sealing contact with the second pipe and the filling process starts again. Given the intake position of the second pipe, it is possible to provide that water will exit through the lower end of the second pipe (ie the end in contact with the tank filling orifice when the body is horizontal) before contact has been made between this end and the port of filling. But this shift does not affect the functioning of the valve.
- the water level adjustment means may be as a tip coming to be positioned on the filling end of the pipe.
- the tip will preferably take the form of a cavity covered with a plate extending the end of the pipe.
- the plate will then include a hole.
- a plate is easily changeable, and one can have a set of plates each having a hole in different positions.
