During the flood period, the head pressure in the turbines is 1 ;; rostany; th bympo; n: ii: i / is repaired, thanks to the increase in the level of roj) H3O: iTa pgg / booklet. and s.udozhestvenno, and goes down

If the outlet is a typical Typ6i tube; i; b; ..; ag; 1ts under the water of the dam) to: with a weir, then dad;) p in the turbines can be increased by forming from a .mill jump of the water flow in the lower pool. In this case, the pressure at the outlet of the suction pipe and, consequently, the pressure in the turbine depends, among other things, on the height e / iiusa above the orifice of the all-in-one pipe n from the discharge of the river.

In order to maintain the laxim. 15.P1Phg.no nanoiia at one of the river discharge costs, it is necessary to replace the height of the discharge.

D, in order to install a kapa in a naiv-odiysssa too.Hi in any mode without any calculations, it is necessary to bring the display of the manometer attached to the mouth of the suction pipe to the place of control of the valve, and, changing the position of the tanana, achieve minimum pressure P1 gauge. This process can be automated.

Valve construction should be simple but sturdy. Cladding is made from thick planks or bars that can withstand ice hits quite easily and easily allow for the replacement of damaged elements. In order to see the blows, it is desirable to include a spring 4 in tu 3 (Fig. 1). Seals should not be arranged, since water leakage is in no way dangerous.

The described device can also be used in the case of a stream jumping off, exit through a nanor hole or a siphon tube. This process can also be automated. At low floods, jump jumps may lead to a lowering of the water level at the end of the water flow, which exposes the suction pipe, which is unacceptable. In order to avoid the possibility of this, the valve can also be used, raising it is easy to maintain the level in front of the suction pipes, ensuring their flooding, of course, by reducing the pressure to the calculated value.

PRIORITY AREA

The weir at the hydroelectric station, characterized in that, as a weir, at its surface, is installed rotatable relative to the horizontal axis to the clans, designed to regulate the distillation of the water leap, thereby obtaining the minimum pressure in the suction pipes and maintaining the nanoshe in the turbines for flood time.
