Description

Technical Field

[0001] The invention relates to the technical field of accumulator structures, in particular to an accumulator structure that is easily disassembled. Background Art

[0002] In hydraulic and pneumatic systems, accumulators are an important energy storage and release device, widely used in various industrial equipment to balance system pressure fluctuations, absorb impact energy, and serve as auxiliary power sources. Traditional accumulator structures often adopt one-piece casting or welding. Although this design has certain advantages in structural strength, it has many inconveniences in actual maintenance and disassembly.

[0003] On the one hand, due to the complex internal structure of the accumulator and the high-pressure working environment, once a failure occurs or maintenance is required, the traditional disassembly and assembly method often requires the use of large tools and professionals, which is not only time-consuming and labor-intensive, but also increases maintenance costs. On the other hand, the sealing method of traditional accumulators mostly uses rubber seals or metal gaskets. These seals are prone to aging or damage under the action of long-term high pressure and medium corrosion, resulting in frequent leakage problems, which seriously affects the performance of the accumulator and the stability of the system.

[0004] In addition, traditional accumulators also have deficiencies in monitoring and control. For example, the lack of intuitive gas pressure monitoring means makes it difficult for operators to grasp the working status of the accumulator in a timely manner, making it impossible to make quick and effective adjustments. At the same time, the installation and disassembly process of the accumulator lacks a convenient design, which greatly reduces the efficiency of maintenance work.

[0005] Therefore, we propose an accumulator structure that is easy to disassemble and assemble to solve the above problems. Summary of the invention

After that, inert gas is injected into the capsule 7 through the two-way pneumatic control valve 4 and the gas pipeline to expand the capsule. At the same time, hydraulic oil is injected into the sealed shell through the oil pipe 14.

[0024] As a preferred technical solution of the present invention, the matching flanges 8 are respectively arranged at the lower end of the upper shell 1 and the upper end of the lower shell 2, the outer wall of the matching flange 8 is provided with a sealing groove 9, and the sealing ring 10 is installed inside the sealing groove 9. The inner end of the outer wall of the matching flange 8 is provided with a clamping groove 11, and an upper clamping block 12 is arranged inside the clamping groove 11 at the upper end, and a lower clamping block 13 is arranged inside the clamping groove 11 at the lower end. The lower clamping block 13 is installed in cooperation with the upper clamping block 12, and the sealing groove 9 is sealed by the sealing ring 10. The splicing clamping installation of the upper shell 1 and the lower shell 2 can be completed by the two clamping grooves 11 and the coordinated clamping installation of the upper clamping block 12 and the lower clamping block 13.

[0025] As a preferred technical solution of the present invention, the upper clamping block 12 is an annular inverted cone convex portion, and the lower clamping block 13 is an annular regular cone convex portion arranged corresponding to the upper clamping block 12, through.

[0026] As a preferred technical solution of the present invention, there are two sealing grooves 9, which are concentric circle shapes with different inner diameters. By setting the sealing grooves 9 to be concentric circle shapes and setting their inner diameters to be different, double sealing protection can be provided, thereby improving the sealing effect of the accumulator structure that is easy to disassemble and assemble.

The upper shell 1 and the lower shell 2 are fixedly installed through the matching flange 8 through the fixing holes 19 and the fixing bolts, thereby completing the splicing installation of the upper shell 1 and the lower shell 2.

[0028] As a preferred technical solution of the present invention, a pressure indicator 5 is arranged on the outside of the valve protection cover 3, and the detection end of the pressure indicator 5 is connected to the two-way pneumatic control valve 4 through the through hole of the side wall of the valve protection cover 3. The gas pressure of the two-way pneumatic control valve 4 can be monitored and displayed in real time through the pressure indicator 5.

[0029] As a preferred technical solution of the present invention, six groups of anti-slip strips 20 are evenly arranged on the outer wall of the upper shell 1 and the outer wall of the lower shell 2, and an indicator light strip 21 is arranged between two adjacent groups of anti-slip strips 20 on the outer wall of the upper shell 1.

During the working process, the capsule is filled with inert gas of rated pressure, and the hydraulic oil enters the shell through the oil pipe 14 and the mushroom valve 16, causing the capsule to deform. As the internal pressure increases, the volume of the airbag becomes smaller and smaller, and then the hydraulic oil stores energy in the gas in the capsule. When the hydraulic system needs hydraulic oil, the oil in the shell is quickly discharged, and the volume of the capsule increases rapidly, thereby transferring the accumulated energy to the hydraulic oil, increasing the pressure of the hydraulic oil in the hydraulic circuit, and providing a larger flow rate for the working element. In this way, the accumulator can absorb and replenish energy, ensure the normal pressure of the hydraulic system, and eliminate pressure fluctuations.

[0031] The circuit connection involved in the present invention is a common method used by those skilled in the art, and technical inspiration can be obtained through a limited number of experiments, and it belongs to the widely used existing technology.

Various changes can be made within the knowledge of ordinary technicians in this field without departing from the purpose of the present invention, and modifications or deformations without creative labor are still within the protection scope of the present invention.
