SU57707A1 - Valve device for hard pontoon - Google Patents

Description

in rigid pontoons used for lifting ships, the mouth holes in the lower part of the pontoons are blocked by ordinary sheet steel covers, which are attracted from the outside by bolts. The cap should be fixed, attached, as well as removed should be done by the diver, moreover, in a very uncomfortable position for him.

The large pontoon has four mouths. Before towing the pontoons to the work site, the necks are covered with covers, and upon arrival at the work site they are opened. In addition, it is almost always necessary to block the openings of the throats during work. The work of installing and removing covers on pontoons is very laborious (from 3 to 4 hours) and is not feasible in any weather.

The proposed valve device is intended to eliminate this inconvenience, for which the valve water discharge valve plate is provided with a central pipe in which valves for filling the pontoon with water are prevented, whereby the opening and closing of the mouth of the neck occurs automatically.

In FIG. 1 shows a vertical section of the valve device along the line AB in FIG. 2 and FIG. 2 - view from above.

To the casing / bolts 19 P1 attached ring 2, surrounding the opening of the neck at the top, and ring 3 surrounding it at the bottom, with a rubber gasket 7. To the last is pressed a movable valve plate 4 of the exhaust valve, fitted along the edge with a rubber gasket 5, pressed to the plate by a plate 21 and bolts 20. Plate 4 is provided with a pipe 6 with an upper disk 10 attached to it, through which edges bolts 9 are held, fixed with their lower ends in ring 5. A lower disk 8 is put on the same bolts 9, between which and the disk 10 there is a spring 11 Inside the center A flax pipe 6 has a disk 16, the stem 17 of which passes through the partition 15 attached to the walls of the pipe 6 and is equipped with a valve 12 with a rubber gasket 13, resting it on the ring stop 14. A spring 18 is placed between the movable disk 16 and the fixed partition 15.

Valve 12 is opened by the pressure of water in that case.

when this pressure exceeds the pressure inside the pontoon, paprnmer, at 0.1 atm. With a smaller difference in pressure, the valve 12 is closed by the action of the spring 18.

Water is removed from the pontoon with the exhaust valve plate 4 open.

All control of the valves is reduced to the air inlet to the pontoon or the release of it from the latter, and the diver’s work at THIS is unnecessary.

The subject matter of the invention.

Valve device for a rigid pontoon, characterized in that the valve plate of the valve outlet for water is provided with a central tube containing valve for it. filling the pontoon with water.
