Schematic diagram of the training tower shown in the drawing.
Training tower consists of a cylindrical body 1 filled with water, dried podveshennogo compartment 2 with the upper bulkhead 3, which is a rescue hatch 4, with the top 5 and bottom 6 of the lid. The upper cover 5 is equipped with pneumatic actuator double acting 7, and the rescue hatch - pneumatophora 8, the fill system rescue manhole and water valve 9 and pipe 10, the system of water discharge from the rescue hatch with valve 11 and pipe 12, derived outside podveshennogo compartment 2. The pipe 13 is common to the filling systems and discharge from the rescue hatch.
System air vent of the rescue hatch includes a valve 14 and line 15 and 16. The pipe 15 is displayed in the upper part of the rescue hatch, and the pipeline 16 - beyond podveshennogo compartment.
Air rescue gear 17, provided with an etching valves 18, is from avtomatprom 22 with pneumatic actuator double acting 7 and the pipe 23 with pneumatophores 8.
On the housing rescue hatch has portholes 24.
The air flow in the cavity 25, 26, 27, 28 of the actuator 7 is accomplished by valves 29, 30, 31, 32 through the pipes 33, 34, 35. The air to the automatic unit 19 is supplied by pipeline 36.
To hold diver, wearing safety equipment, surfacing under the top cover is used restraint FAL 37.
The operation of this device is as follows.
Trainees are podmochennyi compartment 2 under normal pressure, open the bottom cover 6 rescue hatch 4. First, the learner enters rescue hatch 4, connects the hose 21 of the gear 17 with the pipe 20, the gears holding the carbine FAL 37 per stem pneumatophora 8, after which the bottom cover 6 is closed.
In Padmasana compartment 2 open the valve 31 and serves the air from the pipe 33 through line 34 into cavity 25 and 28 of the actuator 7, while communicating with the atmosphere of the cavity 26 through line 35 and valve 29. Then open the valve 14 and begin filling the rescue hatch water from a cylindrical body of the tower 1 through the pipes 10 and 13 by opening valve 9. At the same time begin to feed air into the gear 17 from the pipe 36 through avtok air which is etched through the etching valves 18.
As the filling of a rescue hatch 4 water air cushion in it decreases and fully etched through the pipe 15, the valve 14 and pipe 16 beyond podveshennogo compartment 2. When the water from the pipe 16, the report provides personnel, closes the valve 14 and begin compression of the learner by increasing the air supply to the gear 17 from the automatic block 19. The pressure in the rescue hatch 4 begins to rise and is compared with the pressure of the water column in the tower. When pressure equalization between the rescue hatch 4 and the column of water in the cylindrical housing 1, the air pressure in the cavity 25 pneumatophora 7 opens the top cover 5, and the air from the cavity 28 is bypassed into the cavity 27 from which the pipe 22 is supplied to the disable automatic block 19, and the pipe 23 is fed to disable pneumatophora 8. Holding FAL 37 (not allowing the learner to pop up when filling out a rescue hatch water) is released and the learner emerges due to its positive buoyancy. When the tension of the hose 21 is automatically removing it from the pipeline 20. The actions and status of a student is under constant observation che who apanov 29, 31 and opening valves 30, 32. Rescue Luke 4 ready for sluicing another student, who along with the rest of them were all the time under normal pressure.
In the event of an emergency with the student when the locking instructor-diver immediately relieve pressure and water rescue hatch 4 the opening of the valves 11 and 14, while air cushion equipment 17, from which the breath of the learner, is ventilated by dumping excess air through etching valves 18. Because the air vent and water from a rescue hatch in the pipes 16 and 12 is outside podveshennogo compartment 2, the pressure in Padmasana compartment does not change (remains normal and does not affect other students.
The effectiveness of the training tower is in full security of all students, in Padmasana compartment, as well as in quality improvement tasks, the output of modern rescue hatch with two covers.

SUBSTANCE: mode of decompression of divers includes step-by-step, phased reducing of pressure in an altitude chamber with endurance under pressure at stoppages. At the final stage of decompression the pressure in the altitude chamber is reduced lower than atmospheric by one step of decompression, sustained under that pressure and then the pressure is raised until atmospheric and the process of decompression is accomplished.
EFFECT: increases reliability of moving-off of inert gas out of an organism and prevention of developing of caisson disease.
FIELD: transportation, diving equipment.
SUBSTANCE: training tower has a dry under-tower compartment and an escape hatch with an airport, lower and upper covers, systems of filling and releasing water and air. The escape hatch is furnished with a union coupled with a hose coupler of the diver isolating breathing apparatus. Manifold is arranged outside the tower and is connected by pipes with the breathing system arranged in the under-tower compartment and communicating, via a pipeline, with the hatch inner space. A depth meter is arranged before air port.
EFFECT: chances of training the divers with simulation of separate diver submersion and submersion in underwater apparatus conditions.
SUBSTANCE: air under regulated excess pressure is supplied to the chamber along the input channel through a reducing device from a source of compressed air. Using a system of valves, relief pressure is established and air is let out through the output channel to the relief system. When there is a pre-calculated positive or negative fall of regulated pressure inside the decompression chamber, the input and output valves are closed simultaneously using a device for protection from prohibitive pressure fall.
EFFECT: automatic blocking off of input and output air channels of a chamber when there is a sharp pressure fall inside a chamber and more reliable operation.
