The number of the cushioning members 2 is at least one, the cushioning members 2 are each mounted to the connection member 1, and each cushioning member 2 is formed with a cushioning portion 21, the cushioning portions 21 being located in the flow passage 11.
The buffer portion may have a structure such as a buffer hole or a buffer ball, and the present utility model is not particularly limited herein, as long as the buffer portion can play a role of buffering.
In one embodiment of the present utility model, the buffer portion 21 is provided with a plurality of buffer holes 22, that is, the buffer portion 21 achieves buffering and deceleration of the high-speed oil through the buffer holes 22 with small apertures.
In another embodiment of the present utility model, the buffer portion 21 includes a buffer ball (not shown in the drawings), and a buffer space (not shown in the drawings) is provided in the flow channel 11, and the buffer ball is movably disposed and confined in the buffer space. That is, although the buffer ball is movable in the buffer space, the buffer ball is limited in a space range of the buffer space, so that the buffer ball cannot be separated from the buffer space, and thus the buffer ball is prevented from being washed away by the oil while playing a role of buffering, for example, the buffer space may be a cylindrical space having an inner diameter larger than an inner diameter of the circulation passage 11, and the diameter of the buffer ball is larger than the inner diameter of the circulation passage 11 and smaller than the inner diameter of the buffer space.
Further, if the structure of the connecting member is as follows: the connecting member 1 includes at least two adjusting valve blocks 12, the adjusting valve blocks 12 are internally formed with flow holes 13, the buffer portion 21 is disposed opposite to the flow holes 13, and all the flow holes 13 define the flow passage 11, and then the mounting structure of the buffer ball is as follows: one of the two adjacent regulating valve blocks 12 is formed with a first cylindrical half-groove having an inner diameter larger than the inner diameter of the flow hole 13 thereof in the flow hole 13 thereof, the other of the two adjacent regulating valve blocks 12 is formed with a second cylindrical half-groove having an inner diameter larger than the inner diameter of the flow hole 13 thereof in the flow hole 13 thereof, the first cylindrical half-groove and the second cylindrical half-groove are butted with each other and jointly define a cylindrical buffer space, a buffer ball is movably disposed in the buffer space, and the diameter of the buffer ball is larger than the inner diameter of the flow channel 11 and smaller than the inner diameter of the buffer space.
According to the oil outlet assembly of the embodiment of the utility model, the oil outlet assembly is installed in a mechanical pump mechanism, and the buffer part 21 is provided with the plurality of buffer holes 22 for illustration, two ends of the connecting component 1 are respectively connected with an oil outlet and an oil outlet pipe of the mechanical pump, so that the oil outlet is communicated with the oil outlet pipe through the circulation channel 11, the mechanical pump discharges oil through the oil outlet, the oil flows into the circulation channel 11 of the connecting component 1 through the oil outlet, the oil passes through the buffer part 21 in the process of flowing in the circulation channel 11, at the moment, the oil flows to the tail end of the circulation channel 11 through the buffer holes 22 in the buffer part 21, the oil is buffered after passing through the buffer part 21, at the moment, the oil sprayed out of the oil outlet at a high speed can become the oil flowing at a low speed after flowing out of the circulation channel 11, the oil flowing at the low speed can enter the oil outlet pipe after flowing out of the circulation channel 11, and the subsequent transportation process is carried out through the oil outlet pipe.
In the related art, the oil outlet of the mechanical pump is generally directly connected to the oil outlet pipe structure, and because the flow velocity of oil flowing out from the oil outlet is higher, and the impact force of the oil with high flow velocity is stronger, so that the oil can easily generate stronger impact action on the oil outlet pipe structure after directly entering the oil outlet pipe structure, namely, the pulse slapping effect of the mechanical pump on the oil outlet pipe structure is stronger, so that the risk of damage to the oil outlet pipe structure is larger, if the pipeline design flow direction of the oil outlet pipe is unreasonable, the pipeline strength is weak and other problems are met, serious adverse effects can be generated on the fatigue life of the oil outlet pipe structure, and the advance damage of the oil outlet pipe structure is caused.
The oil outlet component of the mechanical pump provided by the utility model can solve the technical defects in the related art, and particularly, for the oil outlet component provided by the utility model: in the process that the oil flows through the buffer portion 21, the portion of the buffer portion 21 except the buffer hole 22 plays roles of buffering and stopping, namely, after the oil sprayed from the oil outlet at a high speed is buffered and stopped by the buffer portion 21, the flow speed of the oil is reduced, and the oil with a low flow speed passes through the buffer hole 22 and flows out of the circulation channel 11, so that the oil flowing out of the circulation channel 11 becomes the oil with a weak impact force and flows at a low speed.
Like this, because the cushioning effect of buffer 21 on the bolster 2, the high-speed spun fluid of follow oil-out becomes the fluid of low-speed flow after flowing out circulation passageway 11 to reduce the impact force of fluid in the flow in-process, avoid the fluid to damage the oil line structure of low reaches because the impact force is too strong, also reduced the pulse effect of beating of mechanical pump to the pipeline promptly, reduce the impact effect of fluid to the oil line structure, and reduce the adverse effect to the fatigue life of oil line structure, and then guarantee the structural integrity of oil line structure and prolonged its life.
Further, since the connecting component 1 exists independently of the mechanical pump and the oil outlet pipe, personnel can freely design the shape, the inlet and outlet positions of the connecting component 1, the flow direction and other structures of the flow channel 11, so that the connecting component 1 can adapt to different use scenes, and thus the oil outlet assembly can flexibly adapt to different piping and use requirements, for example, the flow channel 11 of the connecting component 1 can be designed into a flow structure with right-angle corners inside so as to adapt to a space structure arranged at a vertical angle between the oil outlet of the mechanical pump and the oil outlet pipe.
The shape, the position of the inlet and outlet, the flow direction of the flow channel 11, and the like of the connection member 1 are not particularly limited in the present utility model, and the flow channel 11 may be provided in the connection member 1, and the buffer 21 may be provided in the flow channel 11.
In summary, according to the oil outlet component of the mechanical pump according to the embodiment of the utility model, the buffer portion 21 disposed in the flow channel 11 plays a role in buffering the high-speed flowing oil, so that the high-speed oil flowing out of the mechanical pump is buffered into the low-speed oil with a lower flow velocity, thereby reducing the impact effect of the oil on the oil outlet pipe structure, weakening the pulse beating effect of the mechanical pump on the pipeline, reducing the adverse effect on the fatigue life of the oil outlet pipe structure, further ensuring the structural integrity of the oil outlet pipe structure and prolonging the service life of the oil outlet pipe structure.
In addition, the connecting part 1 which is independent of the mechanical pump and the oil outlet pipe can be designed into different structures according to different use scenes, so that the oil outlet assembly can adapt to different use scenes and flexibly adapt to different piping and use requirements.
According to some embodiments of the present utility model, two ends of the connecting component 1 are detachably connected with the oil outlet and the oil outlet pipe of the mechanical pump respectively, so that the assembling, maintenance and replacement of the connecting component 1 are convenient, and when the spatial positions of the mechanical pump and the oil outlet pipe are changed, the connecting component 1 with different design structures can be replaced to adapt to different piping and use requirements.
In order to facilitate the adapting of the connecting component 1 to various use situations, a person can prepare the connecting component 1 with various different structures in advance and replace the original connecting component 1 with a new connecting component 1 when the use situation changes. For example, the connection member 1 may have the following structure: the circulation channel 11 is in a straight line shape, the inlet and the outlet are arranged oppositely, or the circulation channel 11 is in a bent shape, the inlet and the outlet are arranged at an included angle, or the circulation channel 11 is in a right angle shape, the inlet and the outlet are arranged at a right angle included angle, and the like.
According to some embodiments of the present utility model, the buffer member 2 is mounted on the connection member 1, wherein the buffer member 2 may be integrally formed with the connection member 1 to be a part of the connection member 1, or the buffer member 2 may be fixed to the connection member 1 as a separate component, and the connection structure and connection manner between the buffer member 2 and the connection member 1 are not particularly limited as long as the buffer portion 21 of the buffer member 2 is provided in the flow channel 11 of the connection member 1.
For convenience of description, a plurality of buffer holes 22 provided on the buffer portion 2 will be described below without loss of generality.
As shown in fig. 1 and 2, in one embodiment of the present utility model, the connection part 1 includes at least two adjustment valve blocks 12, and a buffer member 2 is interposed between two adjacent adjustment valve blocks 12. The regulating valve block 12 has a flow hole 13 formed therein, the buffer portion 21 is disposed opposite to the flow hole 13, and all the flow holes 13 define the flow passage 11.
Therefore, the buffer piece 2 is clamped in through the two adjacent adjusting valve blocks 12, so that the buffer piece 2 is installed and fixed in the connecting part 1, and the structure is simple and the assembly is convenient. For example, the number of the adjusting valve blocks 12 is plural, and the number of the cushioning members 2 is plural, and one cushioning member 2 is sandwiched between every two adjacent adjusting valve blocks 12, however, it should be understood that in a specific embodiment, the cushioning members 2 may not be disposed between every two adjacent adjusting valve blocks 12, that is, the cushioning members 2 may not be disposed between every two adjacent adjusting valve blocks 12.

Further, the adjusting valve block 12 is detachably connected with the cushion member 2. Therefore, the oil outlet assembly is of a detachable split structure, on one hand, as the buffer piece 2 is detachable, a person can replace the buffer piece 2 with different buffer hole 22 pore sizes, so that different buffer grades of oil can be realized through different pore diameters, and different oil flow rates can be further adapted; on the other hand, since the adjusting valve block 12 can be disassembled, the personnel can replace the adjusting valve block 12 with different structures, so that the inlet and outlet positions and the flow directions of the flow channel 11 are changed, and different piping and use requirements are further met, wherein the structures of the shape of the adjusting valve block 12, the flow direction and the shape of the flow hole 13, the aperture size of the flow hole 13, the inlet and outlet positions of the flow hole 13 and the like can be designed according to specific use requirements.
Further, the adjusting valve block 12 and the buffer member 2 may be detachably connected by various connection structures, for example, the adjusting valve block 12 and the buffer member 2 may be detachably connected by a flange connection structure, a bolt connection structure, a magnetic connection structure, an adhesive structure, a snap connection structure, or the like, which is not particularly limited herein.
As shown in fig. 2, the adjusting valve block 12 and the buffer member 2 are described by taking a flange connection structure as an example, a first connecting flange 31 is provided on the adjusting valve block 12, a second connecting flange 32 is provided on the buffer member 2, and the first connecting flange 31 and the second connecting flange 32 are connected by bolts.
According to some embodiments of the present utility model, the number of the adjusting valve blocks 12 may be two, three, four, etc., and the number of the buffer members 2 may be one, two, three, etc., however, the present utility model is not limited to the specific number of the adjusting valve blocks 12 and the buffer members 2.
Further, when the number of the adjustment valve blocks 12 is N, the number of the buffer members 2 is N-1, where N is a positive integer.
As shown in fig. 2, in one embodiment of the present utility model, the number of the adjustment valve blocks 12 is three and is respectively the first, second and third valve blocks 121, 122 and 123, and the number of the buffer members 2 is two and is respectively the first and second buffer members 23 and 24.

As shown in fig. 2 and 4, it is preferable that the aperture of the first buffer hole 231 on the first buffer portion is larger than the aperture of the second buffer hole 241 on the second buffer portion. Thus, the high-speed oil firstly passes through the first buffer hole 231 with a large aperture, the first buffer hole 231 with a large aperture plays a primary role in buffering the oil, and the influence of the change of the flow velocity of the oil caused by the small flow area can be weakened.

According to some embodiments of the utility model, the flow area of the flow channel 11 increases gradually in the direction of the outlet of the mechanical pump towards the outlet line. Like this, because the circulation passageway 11 is loudspeaker form, fluid constantly increases at the in-process flow area of flowing through the circulation passageway 11 to the velocity of flow of fluid constantly slows down, and then plays auxiliary buffering's effect.
