As shown in fig. 1-4, the preferred embodiments of the present application are:

the core for the hydraulic pipe fitting is internally provided with a flow channel 1, the flow channel 1 comprises a main flow channel 11 and a branch flow channel 12 which are arranged in a branched manner, and the outlet of the branch flow channel 12 is communicated with the main flow channel 11 and is opposite to the flow direction of the main flow channel 11; the regulating component 2 is arranged in the branch flow channel 12, the regulating component 2 is suitable for isolating the main flow channel 11 and the branch flow channel 12 under the action of no external force, and the regulating component 2 is suitable for being jacked by the liquid flowing in the main flow channel 11 so as to enable the main flow channel 11 to be communicated with the branch flow channel 12.

Along with development of technology, the pressure resistance requirement of the present hydraulic transmission technology on hydraulic pipe fittings is higher and higher, so that the pressure resistance requirement on cores is higher and higher, therefore, the inventor of the application adopts a technical means that the branch flow channel 12 is arranged on the main flow channel 11, after the hydraulic components are communicated, liquid flows into the main flow channel 11 and the branch flow channel 12 in the same direction, but the liquid flowing into the branch flow channel 12 can turn in the branch flow channel 12, and when the liquid flows out of the branch flow channel 12, the liquid collides with the liquid in the main flow channel 11 or moving in the flowing direction, so that the pressure reduction and speed reduction effects are achieved, the stability of the communication of the hydraulic pipe fittings can be effectively ensured by the cores of the application under a high-pressure environment, and the main principle is that the kinetic energy of the liquid is utilized for counteracting, and the design is simple and ingenious.

However, if only the decompression is realized, when the communicated hydraulic components do not work at high pressure, the situation that the smooth liquid decompression is decelerated to the condition that the normal working requirement of the machine is not met may occur, so in order to solve the problem, the inventor of the application also adds the adjusting component 2 in the branch runner 12, when the hydraulic components do not enter the high-pressure working environment, the adjusting component 2 can separate the branch runner 12 from the main runner 11, so that the hydraulic pipe fittings convey the liquid according to the preset condition, once the machine fails or the communication source is changed, the hydraulic components enter the high-pressure working environment, the adjusting component 2 can be jacked up, and the branch runner 12 and the main runner 11 can be communicated, thereby the application has the functions of automatic detection and automatic adjustment, and the hydraulic pipe fittings are more suitable for practical use.

Further, as shown in fig. 2, in the present embodiment, the angles between the inlet and the outlet of the branch flow channel 12 and the main flow channel 11 are acute angles, that is, the center lines of the inlet and the outlet of the branch flow channel 12 are respectively used as a line, and the two lines are disposed in the first quadrant in the coordinate system with the main flow channel 11 as the X axis, and the angles between the two lines and the main flow channel 11 are acute angles. The above structure can effectively ensure that liquid can enter the branch flow channel 12 through the inlet on one hand, and on the other hand, compared with the main flow channel 11 in actual production, the outlet with a certain angle in the embodiment is more reasonable, the manufacture is simpler, and the collision between the flowing liquid and the liquid in the main flow channel 11 can also be effectively ensured.

In addition, in order to enhance the decompression effect, a plurality of branch flow passages 12 may be provided, and in this embodiment, two branch flow passages 12 are provided and symmetrically provided on both sides of the main flow passage 11.

As shown in fig. 3, in the present embodiment, the adjusting assembly 2 includes an adjusting block 21 and a spring 22, the branch flow channel 12 is provided with an expanding portion 121 at the position where the adjusting assembly 2 is provided, two ends of the spring 22 respectively prop against the bottom wall of the expanding portion 121 and the bottom end of the adjusting block 21, and the spring 22 is suitable for driving the adjusting block 21 to be closely attached to the inner wall of the branch flow channel 12 under the action of no external force, so as to separate the main flow channel 11 and the branch flow channel 12. Therefore, only when the pressure of the liquid reaches the level of the compressible spring 22, i.e., the adjustment block 21 is pushed open, the branch flow passage 12 is opened, and the decompression operation is performed.

Further, as shown in fig. 4, the front end of the regulating block 21 and the front end of the branch flow channel 12 have a trapezoidal structure adapted in cross section. The above structure can make the inner wall of the branch channel 12 abut against the regulating block 21 to balance when the spring 22 is in a state of driving the regulating block 21 to move forward, and the trapezoid structure, i.e. the front end of the regulating block 21 and the inner wall of the front end of the branch channel 12 are both provided with inclined surfaces, so that a gap is generated between the front end of the regulating block 21 and the front end of the branch channel 12 once the regulating block 21 moves in the compressing direction of the spring 22, thereby allowing the liquid to pass.

Also, in the present embodiment, a gap is provided between the inner side wall of the diameter-enlarged portion 121 and the rear end side wall of the regulating block 21 in order to ensure the normal circulation of the liquid;

the supporting block 3 with a protruding structure is arranged on the inner bottom wall of the expanding portion 121, the spring 22 is suitable for being sleeved on the supporting block 3, and when the adjusting block 21 moves along the compression direction of the spring 22, the supporting block 3 is suitable for propping against the adjusting block 21, so that a gap is formed between the bottom end of the adjusting block 21 and the inner bottom wall of the expanding portion 121.

The above structure makes the side wall and bottom end of the adjusting block 21 and the expanding portion 121 have gaps, and the liquid can flow through, so that when the spring 22 is compressed, that is, the adjusting block 21 is propped open, gaps are formed between the circumference side of the adjusting block 21 and the inner wall of the branch flow channel 12, so that the liquid can smoothly flow into the branch flow channel 12.

It should be noted that, the supporting block 3 not only has the function of ensuring the gap between the bottom end of the adjusting block 21 and the inner bottom wall of the expanding portion 121, but also is sleeved with the spring 22, so as to play a limiting role on the spring 22 and prevent the spring 22 from moving transversely during extrusion.
