Description

f

The invention relates to hydraulic engineering, in particular to water dividers for channels with a strong flow regime.

The aim of the invention is to increase the reliability of operation of the divider by reducing hydraulic resistances in the water distribution zone due to the possibility of controlling the flow velocity structure.

FIG. t depicts a divider, a plan view; in fig. 2 shows section A-A in FIG. one; in fig. 3 shows a section BB in FIG. one; in fig. 4 shows a section B-B in FIG. 1J in FIG. 5 is a divider, in a perspective view; in fig. 6 - flow rate corrector.

The divider includes a well 3 located between the inlet channel 1 and the transit channel 2, a branch pipe 4 mated with a side discharge pipe 5. A divider 6 is placed above the well 3 and is made in the form of a horizontal partition of the flax plate mounted by the protrusions 7 attached to the walls of the well 3. The flow divider 6 fixes with between the protrusions 7 through the holes 8 with retainers 9, there is a flow rate corrector 10 mounted on it, made in the form of a moving horizontal bar, having a V-shaped notch 11 from two sides 12 and 13, which are located outside the well 3 and mate with the walls of the inlet channel 1. The corrector 10 is fixed in horizontal guides 14 mounted on the divider 6 and providing movement of the corrector 10 having holes 15, -17, made through guides 14 and divider 6. There are latches 18 in holes 15-17. Pipe 4 contains a choke valve 19 with a mechanism 20 for changing the water flow in the discharge pipe 5.

The divider works as follows.

To ensure the delivery of a predetermined flow rate of water into the well 3, a divider 6 is installed between the protrusions 7 and secured with latches 9, while depending on the hydraulic characteristics of the flow in

The feed channel 1 is pushed into it by the guides 14, the corrector 10 of the flow velocity and secured with its clips 18 (in this position, the sides 12 and 13 of the corrector 10 are mated with the side walls of the feed channel 1). The flow rate corrector 10 is in a horizontal position and enters into operation in front of the water distribution zone, having redistributed the velocity structure of the flow. Since outside the water distribution zone, the flow in the feed canap 1 has in the center of the living section

IS channel 1 speeds greater than that of its side walls, then by placing the flow rate corrector 10 in front of the well 3, with its cutout 11, it transforms from the central zone

2 (1 flow velocity components to the side zones, i.e., to the peripheral part of the living section of the flow.

After offsetting by the corrector 10 the velocity flow structure in

2 $ inlet channel 1 of the flow is directed to transit channel 2, i.e. above the divider 6, the flow channel 2 enters the flow in a parallel-jet form, which prevents the formation of faults, fountains and splash over the structure in the water distribution zone. Another part of the flow is directed under the divider 6 into the well 3, from which one part of the flow returns to the transit channel 2, and the other flows through the branch pipe 4 to the discharge pipe 5.

The parameters of the corrector 10, the velocity jTH of the flow and its expansion into the supply channel 1, ensure the division of the flow and the accuracy of stabilization of the flow entering the well 3.

When the water level in feed channel 1 changes, the position of the divider 6 between the protrusions 7 is adjusted and the corrector 10 is set.
