[0003] For example, Chinese Patent Application No. 201120313674.9 discloses a dual-cylinder filter, including a first filter, a second filter, and a reversing valve connecting the first and second filters via pipes. The first and second filters are connected by upper and lower pipes, with an oil inlet and an oil outlet respectively in the middle of the upper and lower pipes. The reversing valve consists of an inlet reversing valve and an outlet reversing valve, which are connected in the same direction and are respectively installed at the oil inlet and outlet. Beneficial effects: 1. Filter elements can be replaced without affecting the normal operation of the hydraulic system; 2. The pressure at the filter inlet can be monitored, improving the safety of the dual-cylinder filter; 3. Simple structure and low manufacturing cost.

[0004] In the use of flow regulation devices for heavy oil filters for twin-cylinder marine diesel engines, the top cover is usually used to seal the top of the filter. However, when it is necessary to replace the internal filter cartridges, the operators have to disassemble and install multiple bolts one by one. The whole process is tedious, complicated and time-consuming.

[0005] Therefore, it is necessary to redesign and modify the flow regulation device of the heavy oil filter for twin-cylinder marine diesel engines to effectively prevent the complex installation and disassembly process. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1 to 4 As shown, the present invention provides a flow regulating device for a twin-cylinder marine diesel engine heavy oil filter, including a twin-cylinder filter 1. A top cover 2 is threadedly connected to the upper side of the twin-cylinder filter 1. A sealing mechanism is provided on the rear side of the twin-cylinder filter 1. The sealing mechanism includes two L-plates 3 fixedly connected to the rear side of the twin-cylinder filter 1. A sliding block 4 is slidably connected to the inner wall of the L-plate 3. Short rods 5 are fixedly connected to the left and right sides of the sliding block 4. A flip plate 6 is rotatably connected to the surface of the short rod 5. A connecting rod 7 is movably connected to the inner wall of the flip plate 6 through a bearing. The lower end of the connecting rod 7 is fixedly connected to the upper side of the top cover 2. A limit mechanism is provided on the rear side of the top cover 2.

[0023] refer to Figure 3 The limiting mechanism includes a vertical plate 8 fixedly connected to the sliding block 4 and the underside of the flip plate 6. A locking plate 9 is slidably connected to the inner wall of the vertical plate 8 to limit the flip plate 6 from flipping upward, thereby preventing the top cover 2 from loosening. A T-plate 10 is fixedly connected to the rear side of the locking plate 9 to facilitate finger movement and release the locking plate 9 from its limiting position. A tension spring 11 is fixedly connected to the surface of the T-plate 10, and the front end of the tension spring 11 is fixedly connected to the rear side of the L plate 3.

[0024] As a technical optimization of this utility model, by setting a limiting mechanism, the top cover 2 is prevented from loosening, thus ensuring the sealing and stability of the device; when the filter cartridge needs to be replaced, the limiting can be released through a simple operation, which is convenient and quick, taking into account both safety and convenience.

[0025] refer to Figure 4 A magnetic plate 12 is fixedly connected to the front side of the L plate 3. The magnetic plate 12 is used to temporarily fix the position of the flip plate 6 after the flip plate 6 is flipped, so as to facilitate the replacement of the internal filter cartridge.

[0026] As a technical optimization of this utility model, by setting the magnetic plate 12, the operator does not need to continuously manually support the flip plate 6 when changing the filter cartridge, which provides a stable operating environment, further simplifies the replacement process, and reduces the difficulty of operation.

[0027] refer to Figure 2 A diamond-shaped block 13 is fixedly connected to the upper end of the connecting rod 7. The diamond-shaped block 13 is used to facilitate the engagement and rotation of the wrench.

[0028] As a technical optimization of this utility model, by setting the rhomboid block 13, a suitable engagement point is provided for the wrench, which facilitates the use of the wrench for rotational operation. It can be used to adjust the tightness of the top cover 2 or the position of other related components, thereby enhancing the operability and adjustment flexibility of the device.

[0029] refer to Figure 2 A reinforcing block 14 is fixedly connected to the lower side of L plate 3, and the front side of the reinforcing block 14 is fixedly connected to the rear side of the dual-cylinder filter 1.

[0030] As a technical optimization of this utility model, by setting the reinforcing block 14, the connection strength between the L plate 3 and the double-cylinder filter 1 is enhanced, making the entire closed mechanism more stable and reliable, able to withstand greater external forces and vibrations, extending the service life of the device, and reducing the risk of failure caused by loose connections.

[0031] refer to Figure 3 The front side of the flip plate 6 is provided with rounded corners 15, which are used to prevent sharp edges from scratching the operator.

[0032] As a technical optimization of this utility model, by setting a rounded corner of 15, the sharp edges and corners are effectively prevented from causing scratches to the operator, thereby improving the safety of the device and ensuring the personal safety of the operator during operations such as changing the filter cartridge.

[0033] The working principle and usage process of this utility model are as follows: In normal use, the locking plate 9 in the limiting mechanism is in a restricted position under the action of the tension spring 11, preventing the flipping plate 6 from flipping upwards, thus ensuring that the top cover 2 is securely connected to the dual-cylinder filter 1. When it is necessary to replace the internal filter cartridge, the operator moves the T-plate 10 with their finger to overcome the tension of the tension spring 11, causing the locking plate 9 to disengage and releasing the limiting position on the flipping plate 6. At the same time, the operator twists the diamond block 13, causing it to rotate the top cover 2 via the connecting rod 7, thereby disengaging it from the threaded connection with the dual-cylinder filter 1. Then, the flipping plate 6 flips upwards around the short rod 5, simultaneously causing the connecting rod 7 and the top cover 2 to flip upwards. Because the magnetic plate 12 on the front side of the L-plate 3 attracts the flipping plate 6, it is temporarily fixed in a suitable position, providing operating space for filter cartridge replacement. After replacing the filter cartridge, the operation is reversed to return the top cover 2 to its original position, and the locking plate 9 re-limits the flipping plate 6, ensuring that the device returns to a sealed and stable state (the bottom side of the top cover 2 has a built-in sealing ring). The diamond-shaped block 13 at the upper end of the connecting rod 7 facilitates wrench engagement and rotation; the reinforcing block 14 enhances the connection stability between the L-plate 3 and the dual-cylinder filter 1; and the rounded corner 15 on the front side of the flip plate 6 ensures operator safety. Thus, simply turning the diamond-shaped block 13 is sufficient to close and open the dual-cylinder filter 1 to replace its filter cartridges. This avoids the inconvenience caused by the complex installation and disassembly when replacing the filter cartridges of the dual-cylinder marine diesel engine heavy oil filter flow regulating device, making it easy to use.

[0034] In summary, when this utility model is used, the top cover 2 can be quickly installed and removed under the action of the sealing mechanism and the limiting mechanism, thereby replacing the filter cartridge. This avoids the inconvenience caused by the complicated installation and disassembly of the filter cartridge when replacing the filter cartridge of the double-barrel marine diesel engine heavy oil filter flow regulating device, and makes it easy to use.
