Description
Technical field
The utility model relates to a kind of ship stabilizing device, relates in particular to a kind of antirolling tank and air valve offlet thereof.
Background technology
Antirolling tank is a kind of for reducing the special device of ship rolling, and it,, according to " double resonance " principle, has good stabilizing efficiency in the humorous region of shaking.Air valve is the core texture of antirolling tank device, the phase place for water in adjusting cabin at each oscillation period.
As shown in Figure 1, in practical work process, when the liquid level 11 in wing tank 10 vibrates with ship rolling, water often can be splashed into by the gas port 13 of air valve 12 with it in 16 air valves that are connected 12.If the water entering in air valve 12 can not be discharged in time,, when water gathers when a certain amount of, can cause air valve 12 operation irregularities.In addition, long-term ponding also can cause the part corrosion of air valve 12, affects device service life.
The antirolling tank air valve 12 of actual shipment is generally all equipped with offlet 14, and the ponding in air valve 12 is entered to water tank hold 15.Existing offlet 14 is generally straight tube, occurs sometimes that the water in hold 15 enters the phenomenon of air valve 12 by offlet 14 in real work, not only affects the life-span of air valve 12, also can affect air valve 12 and normally work.
Utility model content
Technical problem to be solved in the utility model is that the water overcoming in prior art hold can enter into the defect that air valve affects the normal work and use of air valve by offlet.
In order to solve the problems of the technologies described above, the utility model provides a kind of air valve offlet of antirolling tank, and this offlet comprises offlet, lower offlet and spherical float, wherein:
One end symmetrical openings of one end of offlet and this lower offlet on this, after connecting by flange, the opening on offlet and the open butt joint on this lower offlet form movable chamber on this, and this spherical float is arranged in this activity chamber can be up and down; In the opening of this lower offlet, be provided with at least one drain tank that leads to the hollow space of this lower offlet by the sidewall of this lower offlet.
Preferably, the diameter of this spherical float is greater than the aperture of offlet and the aperture of this lower offlet on this.
Preferably, the width in this activity chamber and be highly all greater than the diameter of this spherical float.
Preferably, this spherical float is solid sphere structure.
Preferably, this spherical float is hollow ball structure.
Preferably, when this spherical float adopts hollow ball structure, wall thickness t is:
Wherein, the external diameter that R is this spherical float, ρ is for making the density of the material of this spherical float, ρ
0density for water.
The utility model also provides a kind of antirolling tank, comprises air valve, also comprises foregoing offlet, and wherein: on this, the other end of offlet is connected with this air valve, the other end of this lower offlet is arranged in the hold of this antirolling tank.
Compared with prior art, embodiment of the present utility model is arranged to offlet upper and lower two ends and float is set therein, and the water in hold can not pour in down a chimney in air inlet valve, and the water efficiently solving in hold pours in down a chimney the problem as air valve.
Accompanying drawing explanation
Fig. 1 is the keystone configuration schematic diagram of antirolling tank in prior art.
Fig. 2 is the structural representation of the air valve offlet of the utility model embodiment.
The specific embodiment
For making the purpose of this utility model, technical scheme and advantage clearer, hereinafter in connection with accompanying drawing, embodiment of the present utility model is elaborated.It should be noted that, in the situation that not conflicting, the embodiment in the application and the feature in embodiment be combination in any mutually.
Fig. 2 is the structural representation of the air valve offlet of the utility model embodiment.As shown in Figure 2, the air valve offlet of the present embodiment mainly comprises offlet 21, lower offlet 22 and spherical float 23.Wherein, the first end of upper offlet 21 is connected with air valve, and the second end of lower offlet 22 is arranged in the hold of water tank, and the second end of upper offlet 21 adopts flange part to be connected with the first end of lower offlet 22.The second end of upper offlet 21 and the first end symmetrical openings of lower offlet 22, after connecting by flange, two open butt joints form movable chamber 24, and spherical float 23 is arranged in this activity chamber 24 can be up and down.Wherein, the diameter of spherical float 23 is greater than the aperture of offlet 21, is also greater than the aperture of lower offlet 22, the width in movable chamber and be highly all greater than the diameter of this spherical float 23.Wherein making spherical float 23 is placed on when waterborne and should swims on the water surface.
In the opening of lower offlet 22, at least one drain tank 222 that leads to lower offlet 22 hollow spaces by the sidewall of lower offlet 22 is set.
If there is ponding in air valve, when water tank rocks with ship, ponding is because the effect of gravity flows into upper offlet 21.Now spherical float 23 is because Action of Gravity Field stops up the opening of lower offlet 22, and ponding flows in lower offlet 22 by the drain tank 222 in lower offlet 22, then by lower offlet 22, flows into the hold of water tank.
If there is at work the water in hold and pour in down a chimney phenomenon in water tank, little owing to making the density of density ratio water of material of spherical float 23, in the effect of buoyancy of water, on spherical float 23, move the opening of upper offlet 21 is stopped up, anti-sealing enters into by upper offlet 23 the normal work and use life-span that air valve affects air valve.
Spherical float in the utility model embodiment can be solid sphere structure (such as baton round), can be also hollow ball structure.When spherical float adopts hollow ball structure, its wall thickness is t, and external diameter is R, and density of material is ρ, and water tightness is ρ
0, for guaranteeing that this structure normally works, spherical float 23 wall thickness must meet:
Embodiment of the present utility model can guarantee that air valve normally works effectively, guarantees that air valve can not pour in down a chimney into water and reduce service life because of offlet.
The antirolling tank of the utility model embodiment, comprises air valve and foregoing offlet, and wherein on this, the first end of offlet is connected with this air valve, and the second end of this lower offlet is arranged in the hold of this antirolling tank.The particular content of relevant the present embodiment, also please refer to the description of aforementioned offlet, does not repeat herein.
Although the disclosed embodiment of the utility model as above, the embodiment that described content just adopts for the ease of understanding the utility model, not in order to limit the utility model.Technical personnel under any the utility model in technical field; do not departing under the prerequisite of the disclosed spirit and scope of the utility model; can do any modification and variation what implement in form and in details; but scope of patent protection of the present utility model, still must be as the criterion with the scope that appending claims was defined.
