Definitions

the invention relates to a depth-controlled blow-out valve device for ejection and drain pipes of submarines, in which a body is pressed out of the pipe by an air blast.
a blow-out device in which a control piston arrangement is used in a compressed air reservoir arranged in the blow-out pipe with a blow-out valve located on it.
oil flows from one side of the control piston to the other side, a throttle which can be adjusted by hand according to the depth of the plunger being arranged in the overflow channel and by means of which the opening speed of the blow-off valve can be influenced.
the control piston arrangement forms a closed hydraulic system together with a low-pressure accumulator.
the known device also has a safety circuit against excessive pressure in the pipe when blowing out.
the invention has for its object to provide a blow-out valve device, in particular for a discharge pipe, which has a blow-out valve which cannot be arranged directly on the compressed-air reservoir and / or pipe in a compact design and a hydraulic system with an adjustable throttle for adjusting the opening speed of the blow-off valve , the throttle adjusts itself automatically according to the diving depth and, if necessary, a constant operational readiness is guaranteed.
the blow-out air can be supplied from any sufficiently large compressed air store.
the blow-out valve is actuated via a control air valve, to which the air is supplied from another pneumatic valve in the boat.
the valve plate of the blow-out valve is in direct connection with the hydraulic system and, when opened, displaces oil from an oil chamber connected to the valve plate.
the oil flows through an adjustable throttle into a variable oil reservoir.
the throttle is adjusted by the external water pressure corresponding to the diving depth, but this is counteracted by a disc spring pact in order to keep the movement of the piston generated by the water pressure small.
a device is preferred as a throttle in which a narrow bore, preferably at right angles, opens into a cylindrical channel in which a piston can be displaced.
the piston merges with a particularly curved transition curve into a piston rod which is connected to a drive piston on which the water pressure can act.
the piston releases the cross-section of the mouth of the narrow bore, whereby the transition curve, depending on the position, provides resistance to the oil flow opposed.
the oil in the hydraulic system can push the valve plate back onto the valve seat. For this purpose, it is pushed back into the oil chamber by spring pressure bypassing the throttle.
blow-out valve device has further details resulting from the subclaims and the exemplary embodiment described with reference to the drawing, such as e.g. a safety circuit to close the valve.
the single drawing shows in part only in a simplified and schematic manner a blow-out valve and a depth-controlled throttle device, which in practice are designed as a composite, compact component and shows the functionally adjacent elements, such as compressed air reservoir and blow-out pipe.
the individual parts are not drawn to each other to scale. Other details that are usually used, such as shut-off valves, pressure gauges, etc., have been omitted.
the blow-out valve device shown comprises the blow-out valve 3, a control air valve 5 and a throttle device 6, the blow-out valve 3 being arranged between a compressed air reservoir 2 and the discharge pipe 1.
a control piston 31 is displaceable by means of control air supplied into the space 35 through a cover 36 from the control air valve 5 via line 51, which is connected via a piston rod 32 through the valve space 34 to a valve plate 33, which seals on a valve seat 37.
the blow-out air flows via the pipe socket 38 and the line 15 or preferably directly from the socket 38 to the discharge pipe 1.
an oil chamber 40 is arranged, the valve plate 33 and the nut 41 of the piston rod 32 sitting on it simultaneously acting as a displacement piston and oil from the oil chamber 40 via lines 42, 43 and can push the bore 64 to the throttle 61.
the oil passes through channels 65, 75 into the oil reservoir 62, where it can move the piston 72 against the pressure of the spring 63.
a proximity switch 74 which reports a possible lack of oil and triggers a warning sign.
the opening of the blow-out valve is visually indicated by the movement of the piston rod 73.
the throttle device 61 is e.g. designed so that the narrow bore 64 opens vertically into a channel 65 and that a piston 66 in the channel 65 has a transition curve 67 at the mouth. Depending on the position of the piston 66, the mouth of the bore 64 is closed or more or less opened and, in conjunction with the transition curve 67, allows oil to flow into the channel 65 in a throttled manner.
a drive piston 68 At the other end of the piston rod 77 there is a drive piston 68, on which the external water pressure acts according to the arrow 70 via a line, not shown.
the piston 68 is displaceable against a set of disc springs 69, in accordance with the water pressure, in a manner in which the throttle 61 is opened accordingly.
the piston 68 is sealed by a bellows 78.
the interior of the bellows 78 and thus also the rear of the piston 68 are connected to the line 51 and the control air valve 5 via the two parallel lines 52, 53 and a further line 54.
air with a pressure of, for example, 25 bar does not only enter the Space 35 of the blow-off valve 3, but also via lines 54, 52 and channel 55 into the bellows 78.
a check valve 56 is arranged in line 52 and opens at a pressure of, for example, at least 10 bar.
a further check valve 57 is located in line 53, which opens at, for example, 0.3 bar when the pressure in the bellows 78 or in the channel 55 is higher than in line 54, and which enables the bellows 78 to be vented.
a throttle 58 can be provided in the line 52 behind the check valve 56. Depending on the setting of the throttle 58, the opening time of the throttle 61 can be influenced. As a result, the final speed of an ejected body can be limited without influencing a necessary initial acceleration.
a throttle 59 can also be useful in line 54.
the blow-out valve device is provided with a safety shutdown, which closes the blow-out valve 3 when an impermissibly high pressure occurs in the discharge pipe 1.
a safety valve 13 the displacement of which creates a connection between the compressed air reservoir 2 and an air chamber 12 via line 14.
the chamber 12 is located next to the oil chamber 40 on the side of the valve plate 33 opposite the valve chamber 34.
the valve 13 When the valve 13 is open, air pushes the valve plate out of the compressed air reservoir 2, in which a pressure of approximately 100 to 250 bar can prevail, against the control air pressure e.g. 25 bar in room 35 in the closed position, so that the inflow of blow-out air to tube 1 is interrupted.
the safety valve 13 is closed, the chamber 12 is kept depressurized via the line 14 and the valve 13.
the invention provides the advantages of the compact design of the throttle device (61) and blow-out valve (3) with the accommodation of this device outside the tube, which is also space-saving due to the compactness and independent of Compressed air reservoir (2) can be connected in a favorable manner.
