Abstract
The utility model relates to a vent pipe dual float-valve of a shallow water type diving apparatus, consisting of an air cylinder, a float chamber, four floating ball chambers, an inlet pipe, and a seawater communicating pipe. When the dual float valve is exposed on the surface of the sea completely, the air flowing from an air port and a top air port of the floating ball chamber flows into the inlet pipe to supply air for the diving apparatus. The seawater infrequently entering into the air cylinder flows into the floating ball chamber from the top air port of the floating ball chamber, and then is discharged through a keyhole. When the floating ball chamber goes into the seawater, the floating ball floats off automatically and clogs the top air port of the floating ball chamber tightly keeping the seawater from entering into the air cylinder. When the air port of the air cylinder is flooded completely by the ocean waves, the float clogs the air port completely so that the seawater can not flow into the inlet pipe through the air cylinder, and the floating ball clogs the top air port of the floating ball chamber keeping the seawater from entering into the air cylinder through the top air port of the floating ball chamber. The dual float valve is under clog state. As long as the air port is flooded incompletely by the ocean waves, the float can not clog the air port and the air can flow into the inlet pipe. The entering seawater through the air port flows down along the gap between the float and the sidewall of the float chamber, and then the entering seawater is discharged into the sea via the seawater communicating pipe.
Description
Technical field
The utility model relates to a kind of submersible float valve, and especially a kind of dual float valve of breather pipe that is used for shallow water type submersible belongs to the equipment in the technical field of ships under water.
Background technology
Present known submersible ventilation breather pipe owing to be provided with unlimited gas port, can not prevent water from flowing into; Breather pipe does not possess the function of sluicing again, so that special-purpose plate washer also will be set to intercept the intrusion of seawater on follow-up admission line.This breather pipe sinks to the sea when following, avoid huge sea pressure in order to make air inlet pipe, have to guide seawater to enter breather pipe, allow seawater all be full of breather pipe, the inside and outside pressure of air inlet pipe is cancelled out each other, structure causes quitting work for a long time of air inlet pipe with the structural destruction of avoiding air inlet pipe, so can not be applicable to the running needs of shallow water type submersible.
Summary of the invention
Can not intercept the deficiency of seawater in order to overcome the ventilation of existing submersible fully with breather pipe, the utility model provide a kind of be applicable to shallow water type submersible can windproof anti-rain, the dual float valve of breather pipe that the opposing wave is attacked.This utility model mainly comprises: inflator, float bowl, four float chambers, air inlet pipe, seawater communicating pipe.Wherein float bowl is the first heavy float valve, and four float chambers are second heavy float valves.Inflator is the cylindrical housings of hollow and thin-walled, and its sidewall is the face of cylinder, and end face is a circular conical surface.The bottom surface is made up of the inflator base plate and the cylindrical-conical inflator base cone face two parts on annular arrangement plane, has circular gas port in the centre of end face.The central vertical of breather pipe and inflator base cone face is joined.Around inflator base cone face, be evenly equipped with four seawater communicating pipes.Uniform four float chambers below annular arrangement inflator base plate.
The base angle is that the round basin shape float bowl at right angle places in the inflator.Interval between the thin-walled upper edge of float bowl and the end face of inflator is narrow and small, air can be passed through smoothly, and seawater seldom enters in the inflator.Seawater communicating pipe is passed the bottom surface of inflator base cone face and float bowl with 45 ° of oblique cuttings, and be connected with the bottom surface soldering of inflator base cone face and float bowl, float bowl is by four seawater communicating pipes and inflator base cone face firm support, and seawater can flow in the float bowl swimmingly from seawater communicating pipe.Placing the float in the float bowl, is the hollow circular cylinder that a thin-walled constitutes, and its bottom surface is the plane, end face be one with the identical circular conical surface of inflator taper end face tapering.The diameter of float is less than the internal diameter of float bowl, greater than the diameter of gas port.When the hollow float rises to the top, can tightly stop up the gas port at inflator end face center.
The first half of float chamber is a cylinder-shaped thin wall, and lower part is the semisphere thin-walled, the two equal diameters and be equal to the width of annular arrangement inflator base plate, and the first half of float chamber is connected by soldering with lower part.The top of four float chambers is connected with annular arrangement inflator base plate by soldering.Center at the annular arrangement inflator base plate that is connected with the float chamber has top, float chamber gas port.Have some apertures on the hemisphere face of float chamber, seawater can be from the random inflow and outflow of aperture.All place a hollow ball float in each float chamber, the diameter of hollow ball float is greater than the diameter of top, float chamber gas port, less than float chamber's internal diameter.
When dual float valve all exposes the sea, from gas port and top, float chamber gas port leaked-in air can be unobstructed the inflow air inlet pipe to the submersible air feed.The seawater that enters inflator once in a while will pass top, float chamber gas port, and to enter the second heavy float valve be in the float chamber, excreted out by the aperture on float chamber's hemisphere face again.When the sea is exposed on dual float valve top, and the float chamber is when invading in the seawater, and the ball float of hollow floats automatically, makes ball float tightly stop up top, float chamber gas port, enters inflator to stop seawater by top, float chamber gas port.Because the bottom surface of inflator is a conical suface, the seawater of Liu Ruing can only stockpile at the minimum position of inflator promptly on the annular arrangement inflator base plate of outer, bottom occasionally, when the float chamber emerges once more, is discharged by the aperture in the float chamber.When wave flooded the gas port of inflator fully, the first heavy float valve was that the float in the float bowl is upwards praised the position of stopping up gas port fully, and seawater impassabitity inflator flows into air inlet pipe.At this moment, the float chamber also is immersed in the seawater, and the ball float of hollow floats, and tightly stops up top, the float chamber gas port at top, float chamber, stops seawater to enter inflator by top, float chamber gas port.The dual float valve of this breather pipe is in blocked state.As long as wave not exclusively floods the gas port of inflator, the first heavy float valve is that the float in the float bowl just can upwards not praised the position of stopping up gas port, and air just can flow into air inlet pipe swimmingly.And will under the gap of float and float bowl sidewall, drop down by the seawater that gas port enters, through seawater communicating pipe leaking into the sea.
The beneficial effects of the utility model are: the complete windproof and rain proof of air system that makes submersible; Resist the attack of wave, guaranteed the functional reliability of shallow water type submersible; And, increase the disguise of operation across the sea because inflator and float bowl have adopted the thin-walled moulding, further improved the survivability of submersible.
