Description

Technical Field

[0001] This utility model relates to the field of hydraulic technology, and in particular to a hydraulic system pressure adaptive regulator. Background Technology

[0002] Mechanical seal adaptive pressure regulators are used to control pressure in applications. By adjusting the inlet pressure level, they maintain a stable outlet pressure. The main function of mechanical seal adaptive pressure regulators is to control the pressure of liquids or gases and adjust it as needed to maintain system pressure stability.

[0003] The regulator uses an integral injection-molded or cast valve body, such as the proportional electromagnetic relief valve of the gearbox. Although this simplifies the assembly process, the stepped hole structure of the internal flow channel is prone to deformation under high pressure due to material stress release, which can cause valve port sealing failure. Therefore, the parts need to be replaced, but the replacement process takes a lot of time, thus indirectly reducing work efficiency. Utility Model Content

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] Example 1:

[0026] Reference Figure 1 and Figure 2 This utility model provides an embodiment of a hydraulic system pressure adaptive regulator, comprising a valve body 1, a connecting frame 2 slidably connected to the top of the valve body 1, multiple bolts 3 slidably connected to the inner walls of the valve body 1 and the connecting frame 2, nuts 4 threadedly connected to the bottom ends of the bolts 3, a sealing frame 5 slidably connected to the top of the connecting frame 2, multiple bolts 6 slidably connected to the inner walls of the connecting frame 2 and the sealing frame 5, nuts 7 threadedly connected to the bottom ends of the bolts 6, a connecting pipe 8 slidably connected to the top of the sealing frame 5, fixing frames 9 slidably connected to both ends of the connecting pipe 8, a moving component slidably connected to the inner wall of the connecting frame 2, a cooling component provided on the inner wall of the valve body 1, a sealing component provided on the inner wall of the sealing frame 5, multiple fixing frames 9 respectively threadedly connected to the outer walls of the valve body 1 and the sealing frame 5, multiple nuts 4 threadedly connected to the outer wall of the valve body 1, and multiple nuts 7 slidably connected to the outer wall of the connecting frame 2.

[0027] Specifically, by placing the connecting bracket 2 on the top of the valve body 1, multiple bolts 3 and nuts 4 are used to fix the valve body 1 and the connecting bracket 2. Then, multiple bolts 6 and nuts 7 are used to fix the sealing bracket 5 to the top of the connecting bracket 2. The bottom end of the connecting pipe 8 is threaded to the valve body 1 through the fixing bracket 9 and fixed to the valve body 1. The top end of the connecting pipe 8 is threaded to the sealing bracket 5 through the fixing bracket 9 and fixed to the top of the sealing bracket 5. This achieves the effect of facilitating the disassembly and installation of the regulator.

[0028] Reference Figure 1 , Figure 3 and Figure 5 The cooling assembly includes a water pipe 16, which is disposed on the inner wall of the valve body 1. One end of the water pipe 16 is equipped with a water inlet pipe 17, and the other end of the water pipe 16 is equipped with a drain pipe 18. One end of the water inlet pipe 17 and the drain pipe 18 are disposed on the inner wall of the valve body 1. The other end of the water inlet pipe 17 is connected to a faucet, and the other end of the drain pipe 18 is connected to a drain pool.

[0029] Specifically, the inlet pipe 17 and the drain pipe 18 are respectively installed at both ends of the water pipe 16 and set on the inner wall of the valve body 1, so that the inlet pipe 17 is connected to the faucet and the drain pipe 18 is connected to the drainage pool, so that cold water enters the water pipe 16 through the inlet pipe 17 and is discharged from the drain pipe 18, thereby facilitating the cooling of the valve body 1.

[0030] Reference Figure 2 The moving component includes a moving rod 10, which is slidably connected to the inner wall of the valve body 1, the sealing tube 21, and the connecting frame 2. A support block 13 is fixedly connected to the outer wall of the moving rod 10. A moving block 11 and a sealing block 14 are fixedly connected to the upper and lower ends of the moving rod 10, respectively. A sealing ring 12 is provided on the outer wall of the moving block 11. A spring 15 is provided at the bottom end of the support block 13 and is located at the top end of the sealing tube 21. The support block 13 is slidably connected to the inner wall of the connecting frame 2, and the sealing block 14 is slidably connected to the inner wall of the valve body 1. The moving block 11 and the sealing ring 12 are slidably connected to the inner wall of the sealing frame 5.

[0031] Specifically, the spring 15, through its elastic force, drives the moving rod 10 upward via the support block 13, causing the sealing block 14 to detach from the valve body 1. When hydraulic oil enters the sealing frame 5 through the connecting pipe 8, it drives the moving rod 10 downward via the moving block 11, causing the sealing block 14 to contact the valve body 1, thus achieving the effect of adaptive pressure adjustment.

[0032] Example 2:

[0033] Reference Figure 3 and Figure 4This embodiment is a further description based on Embodiment 1. The regulator connection is prone to leakage. This embodiment improves on this point. The sealing assembly includes a sealing ring 20, which is disposed between the valve body 1 and the connecting frame 2. A sealing ring 19 is disposed at the top of the sealing frame 5. A sealing groove is opened at the top of the valve body 1. A sealing tube 21 is disposed on the inner wall of the sealing groove. One sealing ring 19 is disposed at the top of the valve body 1, another sealing ring 19 is disposed between the connecting tube 8 and the valve body 1, and the third sealing ring 19 is disposed between the connecting tube 8 and the sealing frame 5. The sealing tube 21 is disposed at the bottom of the connecting frame 2.

[0034] Specifically, by placing two sealing rings 19 between the connecting pipe 8 and the valve body 1, and between the connecting pipe 8 and the sealing frame 5, and fixing them to the valve body 1 and the sealing frame 5 by two fixing brackets 9, the sealing ring 20 is fixed between the connecting frame 2 and the sealing frame 5 by multiple bolts 6 and nuts 7, and the sealing pipe 21 is fixed between the valve body 1 and the connecting frame 2 by multiple bolts 3 and nuts 4, the sealing effect at the regulator connection is achieved.

[0035] Working principle: When hydraulic oil flows from the right side to the left side of valve body 1, the temperature of valve body 1 rises. Then, cold water enters the drain pipe 16 through the inlet pipe 17 to cool valve body 1. The water is then drained into the drain pool through the drain pipe 18. At the same time, hydraulic oil enters the sealing frame 5 through the connecting pipe 8, allowing the hydraulic oil to accumulate in the sealing frame 5 and drive the moving block 11 to descend. The moving block 11 drives the sealing block 14 to move downward through the moving rod 10, causing the sealing block 14 to block the hole inside valve body 1, thereby facilitating the adaptive pressure adjustment of the hydraulic system.

[0036] After the regulator is used, rotate nut 4, nut 7 and fixing bracket 9 respectively to disengage valve body 1, connecting bracket 2, sealing bracket 5 and connecting pipe 8 from each other, so as to facilitate disassembly and installation of the regulator.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
