Description

Technical Field

[0001] The utility model relates to the technical field of energy storage, in particular to a bladder type accumulator. Background Art

[0002] Bladder accumulator is a device that can store liquid or gas energy. It is commonly used in many industrial and mechanical systems. When liquid or gas is pressed into the elastic bladder, the elastic bladder is compressed to store energy. When releasing energy, the bladder can be quickly released through the control valve to convert the stored energy into mechanical energy and provide the required power. This accumulator is often used in hydraulic systems, automobile suspension systems and other applications that require high pressure or short-term energy storage. Its advantages include high-efficiency storage, fast response speed, and high reliability.

[0003] However, during the implementation of the above technical solution, it was found that there are at least the following technical problems: in the process of releasing energy, the valve needs to be opened to allow the pressure oil to be discharged from the accumulator through the oil inlet. At this time, the elastic bag expands rapidly and may directly hit the oil inlet and the valve. The accumulator is generally provided with a mushroom-shaped valve, which has sharp edges. When it contacts the elastic bag, it may cut the elastic bag and damage the elastic bag. Utility Model Content

[0021] 2. When the valve knob is rotated so that the two holes on the valve core are vertically aligned, the holes in the valve core have a larger diameter and can provide a larger flow capacity, which improves adaptability when facing high flow and high pressure environments.

[0029] The embodiment of the present application provides a bladder accumulator, which effectively solves the technical problem that during the process of releasing energy, it is necessary to open the valve to allow the pressure oil to be discharged from the accumulator through the oil inlet. At this time, the elastic bladder expands rapidly and may directly hit the oil inlet and the valve. The accumulator is generally provided with a mushroom-shaped valve, which has sharp edges and may cut the elastic bladder when it contacts the elastic bladder, causing damage to the elastic bladder.

[0030] Example

[0031] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the overall idea of ​​the technical solution in the embodiment of the present application is as follows:

[0032] In view of the problems existing in the prior art, the utility model provides a bladder accumulator, comprising a shell 1, an oil inlet 2, an air inlet 3 and an elastic bladder 6, wherein a sealed elastic bladder 6 is arranged at the upper part of the inner cavity of the shell 1, the oil inlet 2 is located at the lower end of the shell 1, and the air inlet 3 is located at the upper end of the shell 1. The bladder accumulator also includes a valve knob 4, a fixing block 5, a valve body 7, a rotating column 10, a valve core 11, a meshing gear 13, a rotating screw 14 and two rubber rings 9, and the valve body 7 is The upper surface is fixedly connected to the lower surface of the oil inlet 2, and a circular hole 16 is opened at the left end of the valve body 7, the radius of the circular hole 16 is equal to the radius of the rotating column 10, and the right end of the rotating column 10 passes through the circular hole 16 and is rotatably connected to the inside of the valve body 7. The valve core 11 is a circular structure, and circular holes 16 are also opened at the left and right ends of the valve core 11. The valve core 11 is located inside the valve body 7, and the valve core 11 is fixedly connected to the rotating column 10 through two circular holes 16. Holes 16 are opened at the upper and lower ends of the valve core 11. 2. The upper and lower ends of the valve body 7 are fixedly connected with rubber rings 9, and the two rubber rings 9 are movably connected with the upper and lower ends of the valve core 11. When energy is released, the valve knob 4 is rotated, and the valve knob 4 will drive the rotating screw 14 to rotate. Since the rotating screw 14 is meshed and connected with the meshing gear 13, the meshing gear 13 will rotate synchronously with the rotating gear, and the rotation of the meshing gear 13 will drive the rotation of the rotating column 10 and the valve core 11. When the two holes 12 of the valve core 11 are rotated to a vertically aligned position, the pressure oil in the accumulator will flow directly out of the accumulator and the oil inlet 2 along the holes 12, and finally be directly discharged to the oil pipeline 8 through the valve body 7. Due to the reduction of the pressure oil, the elastic bag 6 will continue to expand and increase at this time, and finally the rotary valve knob 4 will be closed again. The two rubber rings 9 are movably connected with the valve core 11, providing good airtightness. When the two holes 12 of the valve core 11 are rotated to a horizontally aligned position, the pressure oil is isolated, so that it cannot be discharged.

[0033] The fixed block 5 is an internal hollow structure, and a circular hole 16 is provided on the right surface of the fixed block 5. The circular hole 16 has the same radius as the circular hole 16 provided on the left surface of the valve body 7 and their positions correspond. The right surface of the fixed block 5 is fixedly connected to the left surface of the valve body 7. The meshing gear 13 is located inside the fixed block 5. The right surface of the rotating column 10 is fixedly connected to the meshing gear 13. When the meshing gear 13 rotates, the rotating column 10 will rotate synchronously. Compared with the common mushroom-type valve, this avoids the phenomenon that when the volume of the elastic bag 6 increases, it may touch the sharp edge of the mushroom-type valve and cause damage to the elastic bag 6.

[0034] The rotating screw 14 is located inside the fixed block 5, and the upper and lower ends of the rotating screw 14 are rotatably connected to the fixed block 5, and the rotating screw 14 is meshed with the meshing gear 13. When the valve knob 4 is rotated so that the two holes 12 on the valve core 11 are vertically aligned, the hole 12 of the valve core 11 has a larger diameter and can provide a larger flow capacity.

[0035] A circular hole 15 is provided on the upper surface of the fixed block 5, and the circular hole 15 is located at the upper end of the rotating screw 14. The lower end of the valve knob 4 passes through the circular hole 15 and is fixedly connected to the upper surface of the rotating screw 14. The lower surface of the valve body 7 is fixedly connected to the oil pipeline 8, which improves adaptability when facing a high flow and high pressure environment.

[0036] Working principle: When releasing energy, rotate the valve knob 4, the valve knob 4 will drive the rotating screw 14 to rotate. Since the rotating screw 14 is meshed and connected with the meshing gear 13, the meshing gear 13 will rotate synchronously with the rotating gear, and the rotation of the meshing gear 13 will drive the rotation of the rotating column 10 and the valve core 11. When the two holes 12 of the valve core 11 are rotated to the vertically aligned position, the pressure oil in the accumulator will flow directly out of the accumulator and the oil inlet 2 along the hole 12, and finally be discharged directly to the oil pipeline 8 through the valve body 7. Due to the reduction of pressure oil, the elastic bag 6 will continue to expand and increase, and finally close the rotation again. The valve knob 4 and the two rubber rings 9 are movably connected to the valve core 11, providing good airtightness. When the two holes 12 of the valve core 11 are rotated to a horizontally aligned position, the pressure oil is isolated, making it impossible to continue the discharge operation. Compared with the common mushroom-type valve, it avoids the phenomenon that when the volume of the elastic bag 6 increases, it may touch the sharp edge of the mushroom-type valve and cause damage to the elastic bag 6. When the valve knob 4 is rotated to make the two holes 12 on the valve core 11 vertically aligned, since the holes 12 of the valve core 11 have a larger diameter, it can provide a larger flow capacity, which improves the adaptability when facing a high flow and high pressure environment.

[0037] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
