Detailed Description
For the connected mode who solves plate-fin heat exchanger among the prior art and pipeline, there is the technical problem who occupies the bigger technical problem of space ratio, the utility model provides a flange subassembly.
Referring to fig. 1 and 2, a flange assembly is characterized by comprising a first flange part 1 and a second flange part 2;
the second flange part 2 is provided with a flange plate 201 and a first annular part 202, wherein the first annular part 202 has a first annular end surface and a second annular end surface, an accommodating cavity is formed between the first annular end surface and the second annular end surface, and the flange plate 201 can cover the accommodating cavity;
the first flange part 1 may be disposed in the receiving cavity.
The first flange part 1 is actually arranged on the plate-fin heat exchanger, and the second flange part 2 can cover the first flange part 1; specifically, the first flange member 1 can be actually welded to the mouth of the plate-fin heat exchanger by brazing, and the receiving cavity of the second flange member 2 is used for receiving the first flange member 1.
The center of the second flange part 2 is provided with a through hole, and in practical use, the pipeline is welded or fixedly arranged at the through hole, that is, the pipe cavity of the pipeline is communicated with the through hole, but the edge of the pipe orifice of the pipeline is sealed with the through hole.
The center of the first flange part 1 is also provided with a through hole, when in actual use, the through hole is communicated with the mouth of the plate-fin heat exchanger, and a gap between the first flange part 1 and the plate-fin heat exchanger is in a sealing state; if the first flange part 1 is soldered to the mouth of the plate fin heat exchanger by means of brazing, the brazing solder should be a sealing structure sealing the aforementioned 'gap'.
In the prior art, the thickness of the mounting flange arranged on the plate-fin heat exchanger and the mounting flange of the pipeline is as follows: the thickness sum of the connecting flange and the mounting flange or the thickness sum of the connecting flange, the sealing gasket and the mounting flange. In the present embodiment, the thicknesses of the first flange part 1 and the second flange part 2 disposed on the plate-fin heat exchanger are: the thickness of the second flange part 2, or the sum of the thicknesses of the second flange part 2 and a part of the first flange part 1.
As is apparent, in the flange assembly provided by the present embodiment, the thickness of the first flange part after the first flange part and the second flange part are actually mounted is smaller than the thickness of the connecting flange and the mounting flange in the prior art under the condition that the thickness of the first flange part is the same as the thickness of the connecting flange in the prior art and the thickness of the second flange part is the same as the thickness of the mounting flange in the center of the prior art.
Therefore, the flange assembly provided by the embodiment can be accommodated in the accommodating cavity of the second flange component through the first flange component, and compared with the connecting flange and the mounting flange in the prior art, the combined thickness of the first flange component and the second flange component is obviously reduced, so that the occupied space of the connecting mode of the plate-fin heat exchanger and the pipeline is actually reduced, and the technical problem of large occupied space of the connecting mode of the plate-fin heat exchanger and the pipeline in the prior art is solved.
In this embodiment, since the first flange member 1 can be accommodated in the accommodating cavity of the second flange member 2, how to provide the first flange member 1 and the second flange member 2 with the hole-type structures for connecting the two members, respectively, becomes a problem to be solved.
Referring to fig. 2, the first annular portion 202 is provided with a plurality of threaded through holes 203;
the first flange part 1 is provided with a plurality of blind threaded holes 101, wherein the number of the blind threaded holes 101 is the same as that of the through threaded holes 203, the axis of any blind threaded hole 101 can coincide with the axis of one of the through threaded holes 203, and any blind threaded hole 101 can communicate with one of the through threaded holes 203.
Any one of the threaded through holes 203 arranged on the first annular portion 202 penetrates through the first annular portion 202, the threaded through hole 203 and the first annular portion 202 form two mouths, and internal threads are arranged in the threaded through hole 203. It should be understood that the axis of the threaded through hole 203 should be intersected with the axis of the first annular portion 202, that is, if the axis of the first annular portion 202 is disposed in the vertical direction, the axis of the threaded through hole 203 should be in an inclined state or a perpendicular state with respect to the vertical direction. In this arrangement, when the screw is used to connect the screw through hole 203, the screw is attached from the side of the second flange member 2.
And, corresponding to the aforementioned threaded through hole 203, the blind threaded hole 101 provided on the first flange member 1 should not be able to penetrate the first flange, and the blind threaded hole 101 forms only one mouth with the first flange, the blind threaded hole 101 being provided with an internal thread. It should be understood that the axis of the blind threaded hole 101 should be crossed with the axis of the first flange member 1, and when the first flange member 1 and the second flange member 2 are actually installed, the axis of the blind threaded hole 101 should be coincident with the axis of the aforementioned through threaded hole 203, so that the same screw can be respectively disposed in a corresponding one of the through threaded holes 203 and a corresponding one of the blind threaded holes 101.
The adoption sets up the trompil direction of screw thread through-hole 203 in the lateral part of second flange part 2, and the corresponding trompil direction of setting up screw thread blind hole 101 in the lateral part of first flange part 1, and what 'obviously has solved the technical problem of how to be provided with the pass structure that is used for the two to connect on first flange part 1 and second flange part 2 because first flange part 1 can hold in the holding chamber of second flange part 2'.
Also, the person skilled in the art should not set the opening direction of the threaded through hole 203 parallel to the axis of the second flange member 2, and correspondingly, should not set the opening direction of the threaded blind hole 101 parallel to the axis of the first flange member 1. This is because the combined thickness of the first flange member 1 and the second flange member 2 is small, and the number of threads in the blind threaded hole 101 and/or the through threaded hole 203 is limited, which may cause insufficient connection strength between the blind threaded hole 101 and/or the through threaded hole 203 and a screw when the screw is installed, and may easily damage the internal threads of the blind threaded hole 101 and/or the through threaded hole 203.
In addition, the threaded through hole 203 and the threaded blind hole 101 are respectively arranged at the side parts of the second flange part 2 and the first flange part 1, so that the mounting angle of the screw contactable with the second flange part 2 is increased when the screw is actually mounted, and the efficiency of mounting and dismounting the screw is improved.
In the present embodiment, the second flange part 2 should have a pipeline welded thereon in practical use. However, how to weld the pipe orifice of the pipeline to the second flange part 2 without affecting the threaded through hole 203 provided in the second flange part 2 is preferably achieved as follows.
Referring to fig. 1 and 2, the second flange part 2 further includes a second annular portion 204;
the second annular portion 204 is disposed on the flange plate 201, wherein the second annular portion 204 and the first annular portion 202 are respectively located on two sides of the flange plate 201.
The second annular portion 204 is used for welding with the pipeline, and the second annular portion 204 and the first annular portion 202 are respectively arranged on two sides of the flange plate 201, so that when the pipeline is actually welded on the second annular portion 204, the distance between the pipeline and the threaded through hole 203 on the first annular portion 202 is increased, and the flange plate 201 has a certain function of isolating the pipeline from the threaded through hole 203. Therefore, the technical problem of how to weld the pipe orifice of the pipeline to the second flange part 2 without influencing the threaded through hole 203' arranged on the second flange part 2 is solved.
In the present embodiment, when the first flange member 1 is accommodated in the accommodating chamber of the second flange member 2, a gap is formed between the outer surface of the first flange member 1 and the inner surface of the second flange member 2, and how to seal the gap becomes a problem to be solved.
Referring to fig. 2, the first flange member 1 is provided with a first annular groove 102 and a second annular groove 103;
the first annular groove 102 and the second annular groove 103 are parallel to each other with a space left therebetween, wherein any one of the blind threaded holes 101 is arranged between the first annular groove 102 and the second annular groove 103;
the first annular portion 202 may cover the first annular groove 102 and the second annular groove 103.
In actual use, the first annular groove 102 is internally provided with a first O-shaped sealing ring; correspondingly, a second O-ring seal should be disposed in the second annular groove 103. When the second flange part 2 is covered on the first flange part 1, the first O-shaped sealing rings can be respectively and tightly contacted with the outer surface of the first flange part 1 and the inner surface of the second flange part 2; similarly, the second O-ring seals can be respectively in close contact with the outer surface of the first flange member 1 and the inner surface of the second flange member 2, so that the gap between the first flange member 1 and the second flange member 2 is sealed by the first O-ring seal and the second O-ring seal.
In addition, after the first flange part 1, the first O-ring, the second O-ring and the second flange part 2 are actually connected, the fluid flowing into the accommodating cavity is firstly blocked by the first O-ring, so that the fluid cannot flow along the direction from the first O-ring to the threaded blind hole 101, and only can flow from the accommodating cavity to the pipeline or the plate-fin heat exchanger. And when a medium (such as air or water, oil and the like) positioned outside the second flange part 2 flows to the gap between the first flange part 1 and the second flange part 2, the medium is blocked by the second O-ring, so that the medium cannot flow to the blind threaded hole 101 along the direction from the second O-ring to the blind threaded hole 101. That is, the blind threaded hole 101 is disposed between the first O-ring and the second O-ring, which can protect the blind threaded hole 101 to some extent.
In the present embodiment, how to weld the first flange member 1 to the plate-fin heat exchanger and maintain the gap between the first flange member 1 and the plate-fin heat exchanger to form a seal is a problem to be solved.
Referring to fig. 2, two end faces of the first flange member 1 are a head end face and a tail end face, respectively, and at least one ring-shaped solder groove 104 is provided on the tail end face.
The ring-shaped solder bath 104 should be filled with solder before the actual soldering of the first flange part 1 and the plate-fin heat exchanger. Thus, after the first flange part 1 is actually welded to the plate-fin heat exchanger, since the solder is confined by the annular solder groove 104, an annular welding portion between the first flange part 1 and the plate-fin heat exchanger is naturally formed, so that the annular welding portion forms an effect of sealing the 'gap between the first flange part 1 and the plate-fin heat exchanger'.
In order to avoid voids such as blisters after the solder is formed into the solder joints, it is preferable to provide at least 2 concentrically disposed annular solder grooves 104 to reduce the likelihood of blisters and to improve the sealing effect between the first flange part 1 and the plate and fin heat exchanger.
In the present embodiment, in the solution provided with the first annular groove 102 and the second annular groove 103, when the first flange member 1 and the second flange member 2 are actually assembled, there may be a case where the gap between the inner surface of the second flange member 2 and the outer surface of the first flange member 1 is relatively small, so that the second flange member 2 is difficult to pass over the 'first O-ring', and finally cannot contact or cover the 'second O-ring'. In order to solve this problem, the following scheme is preferably adopted.
Referring to fig. 2, the first flange part 1 has a truncated cone shape;
the head end surface and the tail end surface are respectively in a circular ring shape, wherein the diameter of the head end surface is smaller than that of the tail end surface;
the second flange part 2 is in a conical cylinder shape;
wherein, the first annular part 202 is in a shape of a cone ring;
the diameter of the first annular end surface is smaller than the diameter of the second annular end surface.
Wherein, the first flange part 1 is set to be in a truncated cone shape, so that the diameter of the first annular groove 102 is smaller than that of the second annular groove 103, that is, when the first O-ring is set in the first annular groove 102 and the second O-ring is set in the second annular groove 103, since the diameter of the first O-ring is smaller than that of the second O-ring, the second flange part 2 can be conveniently covered on the second O-ring over the first O-ring, and the technical problem that the second flange part 2 is difficult to cross the 'first O-ring', and finally can not contact or cover the 'second O-ring' is obviously solved.
On the basis, the following contents respectively propose preferable solutions for the first flange part 1 and the second flange part 2, specifically:
the included angle between the bus of the first flange part 1 and the end surface of the tail part is 45-60 degrees.
The included angle between the generatrix of the second flange part 2 and the second annular end surface is 45-60 degrees.
The axis of the threaded blind hole 101 is perpendicular to the generatrix of the first flange part 1.
The axis of the threaded through hole 203 is perpendicular to the generatrix of the second flange part 2.
Wherein the term bus-bar should be understood as: any straight line on the conical surface or the conical surface.
The bus of the first flange part 1 is arranged to form an included angle of 45 degrees to 60 degrees relative to the tail end face, so that the first flange part 1 is convenient to design and actually process on the one hand, and on the other hand, the blind hole of the flange is further facilitated to increase the depth, and the strength of a screw and the through hole of the flange is improved.
Similarly, the generatrix of the second flange part 2 is arranged at an included angle of 45-60 degrees relative to the second annular end surface, and the action and effect thereof are the same as those of the first flange part 1, and are not described again here.
The above only is the preferred embodiment of the present invention, not limiting the scope of the present invention, all the equivalent structural changes made by the contents of the specification and the drawings, or the direct or indirect application in other related technical fields, are included in the same way in the protection scope of the present invention.
