The purpose of the invention -. improving the accuracy of stabilization of the flow rate of the zod by eliminating the influence of headwater pressure and reducing the metal consumption and expanding the scope. This goal is achieved by the fact that in the system of stabilization of water flow, containing a shutter installed at outlet 1 in the form of an inverted glass 4 pivotally connected to the rocker 10, the float sensor 12 is the level of the lower pool, the stabilizer 16 of the flow rate, the bottom part of the glass 4 is made in the form of bellows 7 , the bottom of which is fixed motionless, and inside the glass 4 s there is a fixed float 5. 1 ill. “

The invention relates to hydraulic engineering, in particular to devices for stabilizing the flow, and can be applied to the tubular outlets of reservoirs with a sharp fluctuation of the water levels of the upstream basin, daily regulation pools, canals.

The purpose of the invention is to improve the quality of stabilization of water flow,

decrease in metal consumption and expansion of a scope.

The drawing schematically shows a system for stabilizing water flow.

The system of stabilization of water flow 15 contains a water outlet 1, laid into the body of the dam 2. At the outlet, a jet deflector 3 is installed, designed with a radius of curvature to provide minimum resistance 20

, of passing the flow.

A shutter is installed above the water outlet in the form of an inverted cup 4, inside of which there is an annular float 5, with an opening 6. The bottom 25 part of the cup is made in the form of a bellows 7, the bottom of which is fixed and closed by a cover 8. The cup 4 is connected with a rocker 10 by means of a pusher 9 which rotates on axis 11, and at the opposite end of the arm of the rocker arm is installed a float sensor 12 of the lower reach, installed in the still-nummer 13, which communicates with the lower reach 14 through the impulse pipe 15. In the lower reach 14 Oromo set flow regulator 16, which modifies the opening with the screw 17, the stabilizer 16, the water flow can be of any design.

The system of stabilization of water flow works as follows.

The flow rate stabilizer 16 is opened with a screw 17 to a certain opening, which corresponds to a certain water flow that comes through the stabilizer with a certain fluctuation of water levels in the lower pool 14 + dB, when the level in the lower pool decreases, the float-type sensor of the lower pool 12 lowers , hydrostatic pressure from the outlet side acts on the annular float 5, which, rising, raises the shutter. Water through the annular slot formed by the lower edge of the glass 4 and the tip of the water outlet enters the lower pool 14, the water level rises, the float sensor 12 of the lower pool floats, through the rocker 10 force is transmitted to the glass 4, which closes the annular gap, reducing throughput . The level of the lower pool decreases, the process continues until the inflow from the outlet 1 is equal to the outflow through the stabilizer 16 flow.

Claims (1)

Claim The system of stabilization of water flow, containing a shutter installed on a water outlet in the form of an inverted cup hinged to a rocker arm shoulder, on the other arm of which a float gauge of the lower pool is installed, a flow stabilizer installed behind the shutter located at the outlet of the water outlet a deflector that differs in that, in order to improve the accuracy of stabilization of water flow by eliminating the effect of headwater pressure, reducing metal consumption and expanding the scope, the bottom part of the glass in Made in the form of a cup of bellows, the bottom of which is fixed motionless, and an annular float is fixed inside the glass.
