Description
Technical field
The utility model is related to a kind of flange assembly, more precisely, being a kind of cooling tower cooling water pipe double containment method
Blue component.
Background technology
Cooling tower is by the use of water as circulating coolant, is absorbed in heat dissipation to air from a system, to reduce water temperature
Device；It is to carry out cold and hot exchange after contacting with air flowing using water to generate steam that its is cold, and steam volatilization is taken away heat and reached
The principles such as evaporative heat loss, convection current heat transfer and radiant heat transfer reduce water temperature to disperse the waste heat generated in industrial or refrigeration air-conditioner
Evaporating radiator, to ensure the normal operation of system, device is generally tubbiness, and therefore named is cooling tower.Cooling tower is that collection is empty
Aerodynamics, thermodynamics, fluidics, chemistry, biochemistry, materialogy, quiet, a variety of such as dynamic structure mechanics, processing technology
The condensation products that section is integrated.
The connecting flange of cooling tower cooling water pipe is easily influenced to cause the sealing ring elasticity that becomes fragile to subtract by cryogen in water pipe
It is weak, and then influence the overall tightness of flange or even cause the leak of cooling water pipe.
Utility model content
The technical issues of the utility model is mainly solved present in the prior art, so as to provide a kind of cooling tower cooling water
Effective double containment flange assembly.
The above-mentioned technical problem of the utility model is mainly what is be addressed by following technical proposals：
A kind of cooling tower cooling water pipe double containment flange assembly, comprising a first flange piece, first flange on piece is equipped with
Multiple first screw holes, first flange on piece weld an outer tube, and the end of outer tube is inwardly formed a contraction flow region, is welded in contraction flow region
One inner tube forms an annular cavity between inner and outer tubes, is equipped with one first seal washer in annular cavity, the flange assembly is also
Comprising a second flange piece, second flange on piece is equipped with multiple second screw holes, and first flange piece and second flange piece match, the
One screw hole and the second screw hole match, and second flange on piece welds a central tube, after first flange piece is connected with second flange piece
Central tube stretches into annular cavity and compresses the first seal washer, and second flange on piece is additionally provided with one second seal washer.
As the utility model preferred embodiment, first seal washer is butadiene rubber washer.
As the utility model preferred embodiment, second seal washer is graphite gasket.
The cooling tower cooling water pipe of the utility model uses bilayer sleeve and Double seal ring structure with double containment flange assembly,
On the one hand the cryogen that can be reduced in cooling water pipe directly acts on the area of sealing ring, another aspect double-layer sleeve structure
Also insulating effect is played to cryogen, makes sealing ring more flexible, sealing effect is more preferably.
Description of the drawings
It in order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only
It is some embodiments of the utility model, for those of ordinary skill in the art, in the premise not made the creative labor
Under, it can also be obtained according to these attached drawings other attached drawings.
Fig. 1 is the structure diagram of the cooling tower cooling water pipe double containment flange assembly of the utility model.
Specific embodiment
The preferred embodiment of the utility model is described in detail below in conjunction with the accompanying drawings, so that the advantages of the utility model
It can be easier to be readily appreciated by one skilled in the art with feature, it is apparent clear and definite so as to be made to the scope of protection of the utility model
Define.
As shown in Figure 1, a kind of cooling tower cooling water pipe double containment flange assembly 1, comprising a first flange piece 10, first
Flange plate 10 is equipped with multiple first screw holes 11, welds an outer tube 20 on first flange piece 10, the end of outer tube 20 is inwardly formed
One contraction flow region 30, one inner tube 40 of welding, forms an annular cavity 41, annular cavity in contraction flow region 30 between inner tube 40 and outer tube 20
One first seal washer 50 is equipped in 41, also comprising a second flange piece 60, second flange piece 60 is equipped with the flange assembly
Multiple second screw holes 61, first flange piece 10 and second flange piece 60 match, and the first screw hole 11 and the second screw hole 61 match,
A central tube 70 is welded on second flange piece 60, first flange piece 10 and second flange piece 60 connect rear center's pipe 70 and stretch into annular
In inner cavity 41 and the first seal washer 50 is compressed, one second seal washer 80 is additionally provided on second flange piece 60.
It is further improved as to the utility model, first seal washer 50 is butadiene rubber washer.
It is further improved as to the utility model, second seal washer 80 is graphite gasket.
The cooling tower cooling water pipe of the utility model uses bilayer sleeve and Double seal ring structure with double containment flange assembly,
On the one hand the cryogen that can be reduced in cooling water pipe directly acts on the area of sealing ring, another aspect double-layer sleeve structure
Also insulating effect is played to cryogen, makes sealing ring more flexible, sealing effect is more preferably.
Only illustrate the mentality of designing of the utility model in one embodiment above, in the case where system allows,
