As shown in fig. 1 and 2, the present embodiment provides a pipe assembly 100 for a compressor pipe, the pipe assembly 100 being capable of connecting a pipe of the compressor with a pipe to form a loop for circulating a heat exchange medium, the pipe assembly 100 includes a first pipe 110 and at least one second pipe 120, the first pipe 110 includes a pipe main body 111 and at least one connecting section 112, the connecting section 112 is connected with an end of the pipe main body 111, the second pipe 120 is connected with the first pipe 110, and when the pipe assembly is applied to a compressor pipe, the second pipe 120 is further connected with other pipes.

Wherein, first pipeline 110 and second pipeline 120 communicate and form the circulation pipeline, are equipped with at least one turn-ups hole 1111 on the lateral wall of pipeline main part 111, and when pipeline subassembly 100 was assembled to the compressor pipeline, other pipelines can be pegged graft and welded in the turn-ups hole 1111 to the side of the circulation pipeline that first pipeline 110 and second pipeline 120 formed has formed the branch road pipeline, with the demand that satisfies the pipeline return circuit overall arrangement of compressor.

It can be understood that the second pipeline 120 is inserted into the connection section 112 and welded to the connection section 112, a weld is formed between an outer wall of the second pipeline 120 and an inner wall of the connection section 112, and the connection section 112 is connected to an end of the pipeline main body 111, so that the second pipeline 120 can be connected to an end of the first pipeline 110, when the second pipeline 120 is inserted into and welded to the first pipeline 110, the second pipeline 120 and the first pipeline 110 can have a longer overlapped pipeline along an axial direction, and accordingly, a welding length between the first pipeline 110 and the second pipeline 120 can be controlled, so as to ensure that a good enough welding performance is achieved, and avoid leakage.

In some embodiments, the length of the weld between the second pipe 120 and the connecting section 112 along the axial direction of the second pipe 120 may be 5mm to 30mm, and the length of the second pipe 120 inserted into the connecting section 112 may be approximately the length of the weld between the second pipe 120 and the connecting section 112, and thus, the length of the second pipe 120 inserted into the connecting section 112 may be 5mm to 30mm.

It will be appreciated that, in order to accurately control the length of the weld between the second pipeline 120 and the connecting section 112, the length of the connecting section 112 can be used to control the length of the second pipeline 120 inserted into the connecting section 112, i.e. the length of the second pipeline 120 inserted into the connecting section 112 matches the length of the connecting section 112, and correspondingly, the length of the weld between the second pipeline 120 and the connecting section 112 along the axial direction of the second pipeline 120 matches the length of the connecting section 112.

For example, the second pipeline 120 and the connecting section 112 may be welded by brazing, for example, the welding may be performed by furnace brazing, before welding, the end of the second pipeline 120 is inserted into the connecting section, the outer diameter of the second pipeline 120 may be slightly smaller than the inner diameter of the connecting section 112, and solder is placed between the outer wall of the second pipeline 120 and the inner wall of the connecting section 112, and after the solder is melted, the outer wall of the second pipeline 120 and the inner wall of the connecting section 112 may be welded together, and the circumferential direction of the second pipeline 120 may be welded on the inner wall of the connecting section 112 by the solder, so as to ensure the reliability of welding.

Illustratively, the length of the weld between the second pipeline 120 and the connecting section 112 may be 5mm, 6mm, 10mm, 15mm, 20mm, 25mm, 28mm, 30mm, and so on, and the specific length of the weld along the axial direction of the second pipeline 120 may be determined according to the cross-sectional dimension of the second pipeline 120, the wall thickness of the second pipeline 120, and the wall thickness of the connecting section 112, which is not specifically limited in the embodiment of the present invention.

It should be noted that the first pipeline 110 and the second pipeline 120 may be circular pipes, that is, the cross-sectional shapes of the first pipeline 110 and the second pipeline 120 are matched, the cross-sectional shapes of the first pipeline 110 and the second pipeline 120 may both be circular, and the corresponding pipeline main body 111 and the connecting section 112 may both be circular pipe sections, in addition, the first pipeline 110 and the second pipeline 120 may also be square pipes, oval pipes, or other tubular structures with regular shapes, which is not specifically limited in this embodiment of the present application.

It can be understood by those skilled in the art that the pipeline assembly 100 provided in the embodiment of the present application uses the pipeline main body 111 to perform transition, the flanged hole 1111 is disposed on the pipeline main body 111, and is welded to the second pipeline 120 through the connecting section 112, so that the second pipeline 120 does not need to be welded to other side branch pipelines through the flanged hole 1111, and thus, a sufficient weld length is ensured, corrosion resistance is improved, and a risk of leakage is reduced.

The specific structure of the first pipeline 110 will be described in detail below.

With continued reference to fig. 1 and 2, in a possible implementation manner, the flanged hole 1111 may protrude from the pipe body 111 in a radial direction of the pipe body 111, and the depth of the second pipe 120 inserted into the connecting section 112 may be greater than the height of the flanged hole 1111, so that when the pipe assembly 100 is applied to a pipe of a compressor, a branch pipe can be inserted into the flanged hole 1111 from the side of the pipe assembly 100.

It can be appreciated that pipeline assembly 100 can be purchased as a single piece, that is, before flanging hole 1111 is connected to another pipeline, first pipeline 110 and second pipeline 120 have been welded to form a single pipeline connection structure, so as to ensure sufficient welding strength and reliability between first pipeline 110 and second pipeline 120, and not be affected by subsequent assembly operations in the compressor pipeline, thereby reducing the risk of leakage when connecting other pipelines at the subsequent flanging hole 1111 position.

In some embodiments, the distance between the connection section 112 and the edge of the flanging hole 1111 may be greater than or equal to 2mm, so as to ensure that the flanging hole 1111 and the connection section 112 have a sufficient design distance and a safe distance, thereby facilitating the formation of the flanging hole 1111, and avoiding the influence on the connection position between the connection section 112 and the pipeline main body 111 when the flanging hole 1111 is connected to other pipelines.

It is understood that the diameter of the flanged hole 1111 may be smaller than the diameter of the pipe body 111, the flanged hole 1111 may be formed by a hole drawing process, and the distance between the connection section 112 and the flanged hole 1111 may include, but is not limited to, 2mm, 2.5mm, 3mm, 4mm, 5mm, 7mm, 10mm, 20mm, 30mm, and the like, which is not specifically limited in this embodiment.

For example, the first pipeline 110 may be a copper pipe, and the second pipeline 120 may be a steel pipe, so that the copper pipe is used as a pipeline for transitional connection, and the pipeline length of the steel pipe may be longer, so as to reduce material cost, as can be understood by those skilled in the art, the heat conductivity coefficient of the steel pipe is small, the heat conduction is slow, a non-uniform heat affected zone may be formed at a place where welding flame is directly radiated during a welding process, and a tensile stress may exist at a cold-hot junction in a high-temperature zone during cooling.

In addition, because the distance between the flanging hole 1111 and the connecting section 112 is controlled, namely the distance between the flanging hole 1111 and the second pipe section is controlled, the pipeline assembly 100 serves as a connecting structure, the copper pipe can play a transition role, the cost of the steel pipe can be reduced, when the flanging hole 1111 on the copper pipe is connected or welded with a subsequent pipeline, the second pipeline 120 is prevented from being influenced by direct flame radiation, the heat affected zone of the steel pipe is reduced, and the leakage risk can be reduced.

In a possible implementation, the outer diameter of the second pipeline 120 and the inner diameter of the connecting section 112 may be matched, the inner diameter of the connecting section 112 may be larger than the inner diameter of the pipeline main body 111, and the end of the second pipeline 120 may abut against the connecting position of the connecting section 112 and the pipeline main body 111.

It can be understood that, when the first pipe section and the second pipe section are connected, the end of the second pipe section is inserted into the connecting section 112, and then the second pipe section is welded with the connecting section 112, that is, the relative position of the second pipe section and the first pipe section is determined, and the insertion of the second pipeline 120 in the connecting section 112 can be limited by the pipe diameter difference between the pipeline main body 111 and the connecting section 112, so that the length of the weld joint between the second pipeline 120 and the connecting section 112 is controlled within a reasonable range.

It should be noted that the diameter of the first pipeline 110, the diameter of the pipeline main body 111, and the diameter of the connecting section 112 may be designed according to a flow cross-sectional area required by a flow medium required in the pipeline assembly 100, and this is not particularly limited in the embodiment of the present invention.

It is understood that the first pipeline 110 may be an integrally formed part, and the necking section 113 may form a flaring pipeline structure between the connecting section 112 and the pipeline main body 111, so as to improve the convenience of assembling the first pipeline 110 and the second pipeline 120, and thus facilitate the integral forming of the first pipeline 110.

In a possible implementation manner, two ends of the pipeline main body 111 are through, the number of the connecting sections 112 is two, and the two connecting sections 112 are respectively connected to two ends of the pipeline main body 111, that is, the first pipeline 110 is a pipeline structure with two through ends, the number of the second pipelines 120 is two, and the two second pipelines 120 are respectively connected to the two connecting sections 112.

It should be noted that, when the pipeline assembly 100 is applied to a compressor pipeline, two first pipelines 110 at two ends of the first pipeline 110 may be respectively connected to the compressor pipeline to play a role in series connection with the pipeline, that is, the first pipeline 110 and the second pipeline 120 may be main through pipelines, and the flanging hole 1111 may form a flow branch at a side of the main through pipeline.

For example, the pipe main body 111, the two connecting sections 112, and the two second pipes 120 may be coaxially disposed, that is, the first pipe 110 is a straight pipe, and the second pipe 120 and the first pipe 110 extend in the same direction, so that convenience in manufacturing and molding the first pipe 110 may be improved, and meanwhile, the second pipe 120 and the first pipe 110 may be assembled conveniently, and in addition, the second pipe 120 may also be a bent pipe or a pipe with another shape according to requirements of an application, for example, the second pipe 120 may be an L-shaped pipe, which is not specifically limited in this embodiment of the present application.

With continued reference to fig. 1 and 2, in some embodiments, there may be one flanging hole 1111 in the pipe body 111, and one flanging hole 1111 may be located in the middle of the pipe body 111, that is, the distance from the center of the flanging hole 1111 to the connecting sections 112 at the two ends of the pipe body 111 may be equal, and the flanging hole 1111 is connected with other components at the side of the pipe body 111 to form a branch.

It can be understood that the external connection components corresponding to different flanging holes 1111 may be the same or different, for example, different flanging holes 1111 may be welded to the external copper pipe, or a part of flanging holes 1111 may be welded to the external copper pipe, and a part of flanging holes 1111 may be connected to the valve, in addition, the medium flowing directions corresponding to different flanging holes 1111 may be the same or different, that is, the medium flowing through the flanging holes 1111 may flow out from the pipe main body 111 through the flanging holes 1111, or the medium flowing through the flanging holes 1111 may flow into the pipe main body 111, which is not specifically limited in the embodiment of the present application.
