[0011] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0013] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0014] like Figure 1 As shown, the multi-channel oil outlet control joint includes a pipe body, which is provided with an oil inlet section 1, a main body section 2 and an oil outlet section 3 in sequence. A front spring seat 4 is fixedly installed in the oil inlet section 1, and an oil inlet channel 5 is arranged inside the front spring seat 4. One end of the front spring seat 4 extends out of the oil inlet section 1 and is provided with an oil inlet port 6 connected to the oil inlet channel 5. The other end of the front spring seat 4 is located in the oil inlet section 1 and is provided with a front spring port 7 connected to the oil inlet channel 5. A front spring 8 is arranged in the oil inlet channel 5. One end of the front spring 8 is limited in the oil inlet channel 5, and the other end is connected to a steel ball seat 9. A steel ball groove 10 is provided on the steel ball seat 9, and a steel ball 11 is arranged in the steel ball groove 10. A central insert 12 and a rear spring seat 13 are arranged inside the main body section 2. The rear spring seat 13 is fixed in the main body section 2, and an oil outlet channel 14 is arranged in the rear spring seat 13. One end of the spring seat 13 is provided with an oil outlet 15 connected to the oil outlet channel 14, and the other end is provided with a movable port 16 connected to the oil outlet channel 14. A cover plate 17 is provided in the movable port 16. A rear spring 38 is provided in the oil outlet channel 14. One end of the rear spring 38 is limited in the oil outlet channel 14, and the other end is fixedly connected to the cover plate 17. The central insert 12 is located between the steel ball 11 and the cover plate 17. The central insert 12 is fixedly connected to the pipe body. The middle of the central insert 12 is provided with a central channel 18. A plurality of side channels 19 are provided around the central insert 12. The middle of the cover plate 17 is provided with a central hole 20 connected to the oil outlet channel 14. The steel ball blocks one end of the central channel 18, and the central hole 20 is connected to the other end of the central channel 18. The cover plate 17 covers all the side channels 19. The oil outlet 15 is connected to the inside of the oil outlet section 3. After passing through the oil inlet channel 5 and the side channel 19, the oil pushes open the cover plate 17 and enters the oil outlet channel 14, and flows out from the side oil outlet hole 21 and the oil outlet 15 into the oil outlet section 3. When the oil supply at the oil inlet 6 stops or the oil pressure is too low, the oil cannot overcome the elastic force of the rear spring 38 to push open the cover plate 17, and thus cannot enter the oil outlet channel 14. At the same time, the oil in the oil outlet channel 14 cannot enter the oil inlet channel 5, making the oil outlet control joint unidirectional.

[0015] Furthermore, a plurality of side oil outlet holes 21 are provided around the rear spring seat 13, and the side oil outlet holes 21 are connected to the inside of the oil outlet section 3. The side oil outlet holes 21 improve the oil outlet efficiency.

[0016] Furthermore, an annular groove 22 is provided inside the main body section 2, and the movable opening 16 of the rear spring seat 13 is stuck in the annular groove 22. A support platform is formed between the inside of the main body section 2 and the inside of the oil outlet section 3. The diameter of the rear spring seat 13 is larger than the inner diameter of the oil outlet section 3. The cover plate 17 is provided with a protrusion for the rear spring 38 to be sheathed, and the diameter of the protrusion is larger than the diameter of the oil outlet 15. When the oil pressure entering the oil inlet channel 5 at the oil inlet 6 is too high, the high-pressure oil compresses the rear spring 38 in the oil outlet channel 14 to push the cover plate 17 to move, so that the surrounding of the rear spring seat 13 moves away from the annular groove 22. Finally, the support platform blocks the rear spring seat 13, and the protrusion blocks the oil outlet 15, thereby preventing the high-pressure oil from continuing to flow to the oil outlet section 3, forming protection for the rear end components.

[0017] Further, one end of the steel ball seat 9 is provided with a plug-in column 23 inserted into the interior of the front spring 8. The plug-in column 23 plays a limiting role in the deformation of the front spring 8.

[0018] Furthermore, the inner diameter of the oil inlet channel 5 gradually increases, and a retaining ring 24 is provided on the steel ball seat 9. After the plug-in column 23 is inserted into the front spring 8, the retaining ring 24 blocks the front spring 8. The inner diameter of the maximum inner diameter of the oil inlet channel 5 is greater than the diameter of the retaining ring 24, and the inner diameter of the minimum inner diameter of the oil inlet channel 5 is smaller than the diameter of the retaining ring 24. When the oil pressure in the oil outlet section 3 is too large, the oil pressure will flow in the opposite direction through the oil outlet channel 14 to the side channel 19 and the central channel 18. The high-pressure oil in the central channel 18 will overcome the elastic force of the front spring 8, push the steel ball 11 open, and move the steel ball seat 9 toward the oil inlet port 6 until the retaining ring 24 contacts the inner wall of the oil inlet channel 5. The retaining ring 24 and the steel ball seat 9 together make the oil inlet channel 5 disconnected, preventing the high-pressure oil pressure from flowing out of the oil inlet port 6 in the opposite direction to damage the pipeline and components such as the high-pressure oil pump.

[0019] It is worth mentioning that the technical features such as springs involved in the patent application of this invention should be regarded as prior art. The specific structure, working principle and possible control method and spatial arrangement method of these technical features can be selected by conventional methods in the field and should not be regarded as the inventive point of this patent. This patent will not be further elaborated.

[0020] The preferred specific embodiments of the present invention are described in detail above. It should be understood that ordinary technicians in this field can make many modifications and changes based on the concept of the present invention without creative work. Therefore, all technical solutions that can be obtained by technicians in this technical field through logical analysis, reasoning or limited experiments based on the concept of the present invention on the basis of the existing technology should be within the scope of protection determined by the claims.
