Background technology
Reclamation by pumping filling is an important directions for dredging industry, with the increasingly raising to environmental requirement, is provided using offshore sand
The engineering that source carries out land reclamation has been gradually decreased, and substantial amounts of heavy construction is needed using large dredger from the sea away from seashore
Area takes sand, and by dredging tube hydraulic reclamation to designated area, this kind of engineering working condition is often poor, and blows away from also more and more remote,
Therefore it is the important topic for dredging industry that sand and hydraulic reclamation how are effectively taken using dredger.
Dredger when carrying out hydraulic reclamation using dredging tube, it is necessary to the dredge pipe on ship is connected with the dredging tube in hydraulic reclamation area,
At this moment, it is filled with air in mud pipe.The dredge pump discharge capacity that dredger is used to blow mud is generally larger, and flow is usually in 10000m3/ h with
On, even up to close to 20000m3/ h, at this moment, proposes high requirement, it is necessary to which it as early as possible will to the breather valve on dredging tube
Inner air tube is discharged.
In conventional practice, a kind of breather valve of cylindricality float was designed, its shape ensure that the larger ball pressure that rises, but
It is due to employ cylindricality, float center of gravity is higher, also is difficult to ensure that float center of gravity keeps on centerline, causing in practice processing
It is crooked after float floating, it is impossible to closed ventilation mouth, cause dredging tube to leak mud.

Embodiment
Preferred embodiment of the present utility model is described in detail below in conjunction with the accompanying drawings, so that advantage of the present utility model
It can be easier to be readily appreciated by one skilled in the art with feature, so as to make protection domain of the present utility model apparent clear and definite
Define.
Refering to shown in Fig. 1-5, dredger dredging tube of the present utility model is with double float breather valves, and it includes：
Valve seat 1, bottom is connected with dredging tube 2, and the inside of valve seat 1 is additionally provided with the first dividing plate 3, and the first dividing plate 3 is provided with
First through hole 4；The first dividing plate 3 in the utility model is shaped as cross but it is also possible to be other suitable shapes, first every
The main function of plate 3 is the first float 6 of support；
Lower house 5, bottom is connected with valve seat 1, and the inside of lower house 5 is additionally provided with the first float 6 and second partition 7, the
One float 6 is movable to be arranged between the first dividing plate 3 and second partition 7, and second partition 7 is fixedly connected with lower house 5, and second
The second through hole 8 is additionally provided with dividing plate 7；
Upper shell 9, upper and lower ends are connected with permeability cell 10 and lower house 5 respectively, and the inside of upper shell 9 is additionally provided with second
Float 11, the second float 11 is connected by connecting rope 12 through second partition 7 with the first float 6, wherein, the second float 11
Entrance of the position also with permeability cell 10 is corresponding.
In the utility model, when being exhausted, larger air-flow is sequentially entered in lower house 5 and upper shell 9 through valve seat 1,
When blowing the second float 11 floating, the first float 6 can hold the second float 11, it is to avoid it closes the entrance of permeability cell 10,
Ensure smooth in exhaust.When exhaust is completed, filled in valve seat 1 after muddy water, the first float 6 floats, and connecting rope 12 loosens, so that second
Float 11, which floats, closes the entrance of permeability cell 10, will not can in advance close permeability cell 10 on the premise of capacity is met,
Ensure that the air in dredging tube 2 is normally discharged, meanwhile, it also has low cost, simple in construction, good reliability etc. excellent
Point.
Specifically, in order to increase sealing when closing permeability cell 10, it is close that the porch of permeability cell 10 is additionally provided with a taper
Seal 13, conical seal ring 13 is corresponding with the position of the second float 11.
Preferably, mount and dismount for convenience, lead between valve seat 1 and lower house 5, between lower house 5 and upper shell 9
Flange 14 is crossed with bolt 15 to be connected.In the present embodiment, the shape of the first float 6 and the second float 11 is respectively cylinder and ball
Shape.Under different use occasions, the first float 6 and the second float 11 can also be arranged to other shapes.
Specifically, in order to avoid the length of connecting rope 12 is too short, sealing of the second float 11 of influence to the entrance of permeability cell 10,
The length of connecting rope 12 is more than the spacing between conical seal ring 13 and second partition 7.
Operation principle of the present utility model is:
When enter the air velocity in valve seat 1 it is too fast when, can by rise less spherical second float 11 of ball pressure blow afloat,
But not larger cylindrical first float 6 of ball pressure will be played to blow afloat.Cylindrical first float 6 can hold ball by connecting rope 12
The second float of shape 11, makes it can not reserve enough exhaust passages close to conical seal ring 13, so that it is guaranteed that breather valve continues to arrange
Gas.
Inside the muddy water in exhaust completion, dredging tube 2 is by valve seat 1, and cross partition 3 is flowed through into lower house 5
In, at this moment muddy water begin to fill with the surrounding space of the first float 6, after buoyancy is enough, and the first float 6 starts to float, and withstands the
Two dividing plates 7.After the first float 6 floats, muddy water can be entered in upper shell 9 by the second through hole 8 of second partition 7, and be filled
The surrounding space of second float 11, because the first float 6 has floated, enough, therefore the second float 11 can be with for the length of connecting rope 12
Float always until closely knot is touched with conical seal ring 13, so as to completely close the entrance of permeability cell 10.
More than, embodiment only of the present utility model, but protection domain of the present utility model is not limited thereto,
Any change or replacement expected without creative work, should all cover within protection domain of the present utility model.Therefore,
Protection domain of the present utility model should be determined by the scope of protection defined in the claims.
