FIELD: training.
SUBSTANCE: invention relates to devices for training during laboratory work on the course "Hydraulics". It consists of a pressure tank with a water supply, a water meter, a piezometer-level gauge made of a transparent tube, water outlets made directly in the shield-shutter, whose axis of rotation is located with some eccentricity relative to the large main loop in the front wall of the pressure tank. Holes in the shutter-plate are located on one circle so that when the shutter-plate rotates around the axis, the centers of the water outlets coincide with the center of the large loop in the wall of the pressure tank. To avoid leakage during the experiment and during rotation of the shutter-plate, a seal is provided in the form of a cuff-torus inserted into the circular groove located on the outside of the large loop. Proper bearing of the shutter-plate to the cuff is provided by an axis-bolt with plates, a spring and a screw.
EFFECT: implementation of the invention will save time, water consumption, obtained from centralized water supply, or electrical energy in laboratory circulating water supply by means of pumps.
