Drawings
The utility model is further illustrated by the following examples in conjunction with the accompanying drawings:
FIG. 1 is a block diagram of the present utility model;
fig. 2 is a top view of the present utility model.
In the figure: the device comprises a supporting cross beam 1, a hinge shaft 2, a balance rod 3, a first suspender 41, a second suspender 42, a pontoon 5, a centering valve cover 6, a drain pipe 7, an adjusting tank 8 and a pontoon adjusting groove 9.
Detailed Description
Example 1:
for example: in Nile region, operation and maintenance cost and the like need to be considered when hydraulic equipment is selected. In order to conveniently and rapidly adjust the downstream water level in agricultural water intaking, the device capable of automatically adjusting the water quantity is required to be installed for irrigation, so that the agricultural production requirement is met, and the specific scheme is as follows:
the preferred scheme is as shown in fig. 1-2, and the automatic float-type regulating valve comprises a supporting cross beam 1, wherein the supporting cross beam 1 is connected with a balance rod 3 through a hinge shaft 2, one end of the balance rod 3 is connected with a float 5 through a first suspender 41, the other end of the balance rod 3 is connected with a centering valve cover 6 through a second suspender 42, and the centering valve cover 6 is used for plugging a drain pipe 7. The utility model is mainly used for adjusting the irrigation water level in the adjusting tank 8, water flows out of the conical adjusting port of the drain pipe 7, the water outlet is closed when the centering valve cover falls down, the outlet is opened when the valve cover rises up, and irrigation water enters the adjusting tank.
The water outlet end of the drain pipe 7 is provided with an adjusting tank 8, a pontoon adjusting groove 9 is arranged in the adjusting tank 8, the pontoon 5 is positioned in the pontoon adjusting groove 9, the pontoon adjusting groove 9 is provided with a water permeable hole or a water permeable net, and the water permeable hole or the water permeable net is used for enabling the water level of the pontoon adjusting groove 9 to be communicated with the adjusting tank 8.
The moment arm of the pontoon 5 is longer than the moment arm of the middle valve cover 6. The supporting beam 1 is fixed with the adjusting tank 8. The whole valve body is in the equalizing basin, and concrete supporting beam is spanned in equalizing basin both sides, and pre-buried pipeline i.e. drain pipe 7 gets into from the bottom, is cylindric flotation pontoon adjustment tank in the middle of the equalizing basin, and there is the inlet port in the bottom in order to guarantee to be unanimous with the equalizing basin water level, and the most downstream side is the export of connecting irrigation canal.
The working principle is as follows:
the supporting cross beam is used as a hinge point, moment at one end of the pontoon is larger than that of the centering valve cover in a water-free state, the valve cover is in a fully-opened state, irrigation water enters the regulating tank at the moment, the water level starts to rise, the water level of the pontoon regulating tank is consistent with that of the regulating tank, moment on two sides is balanced when the water level reaches the lowest water level of the regulating tank, the centering valve cover starts to slowly fall along with the rising water level, water enters the regulating tank due to water pressure at an outlet, when the water level reaches the highest water level, the movable centering valve cover is in butt joint with the conical regulating port to close the outlet, water in the regulating tank is discharged from a downstream outlet to the irrigation canal, the water level of the regulating tank starts to fall, the pontoon also starts to fall, and the water outlet is opened again.
And closing the regulating valve until the maximum water storage level of the downstream water is reached. The above embodiments are only preferred embodiments of the present utility model, and should not be construed as limiting the present utility model, and the scope of the present utility model should be defined by the claims, including the equivalents of the technical features in the claims.
