Description

Technical Field

[0001] The utility model relates to the technical field of valves, in particular to a valve with a self-cleaning function. Background Art

[0002] Valve is an important fluid control device that controls the flow, pressure and direction of the fluid by changing the size of its flow area. There are many types of valves, the most common ones are gate valves, stop valves, plug valves, ball valves, butterfly valves, diaphragm valves, check valves, etc. They are widely used in many fields such as industry, construction, water treatment, petroleum, chemical industry, etc. to ensure the safe and stable operation of fluid systems. According to the different working temperatures and pressures, valves are also divided into different types such as normal temperature valves, high temperature valves, ultra-low temperature valves and ultra-high pressure valves. It is crucial to choose the right valve model and specifications to ensure efficient and reliable operation of the system.

[0003] In the current valve design, although most valves have a certain filtering function, they can block impurities in the fluid and prevent them from entering the system, thereby protecting the safety and performance of downstream equipment. However, these valves are usually not equipped with a special cleaning mechanism, so that the filtered impurities accumulate on the filter screen for a long time. Over time, this accumulation leads to a reduction in the flow area of ​​the valve, which in turn causes blockage problems. This blockage not only affects the normal flow of the fluid and increases energy consumption, but also has a chain reaction on the entire system, causing equipment failure or performance degradation.

[0004] In view of the above problems, a valve with a self-cleaning function is proposed to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] Reference Figure 1 - Figure 6The utility model provides an embodiment: a valve with a self-cleaning function, including multiple flanges 2, one side of two flanges 2 is fixedly connected to a connecting pipe 4, a valve body 1 is arranged between the other two flanges 2, multiple screws 9 are arranged inside the flange 2, nuts 8 are threadedly connected to the outer side of the screws 9, the outer side of the flange 2 is fixedly connected to a connecting pipe 4, the outer side of the connecting pipe 4 is fixedly connected to a fixing ring 5, a fixing assembly is arranged inside the fixing ring 5, and the fixing assembly is used to fix the nut 8 and the screw 9, a filter screen 14 is arranged inside the valve body 1, a motor 15 is fixedly connected to the outer side of the valve body 1, and a connecting rod 16 is fixedly connected to the output end of the motor 15, and the connecting rod A bevel gear 26 is fixedly connected to the bottom end of one 16, a connecting rod 24 is rotatably connected inside the valve body 1, a half gear 17 is fixedly connected to the outer side of the connecting rod 24, one end of the connecting rod 24 is fixedly connected to a bevel gear 25, two limit blocks 20 are fixedly connected inside the valve body 1, a moving block 21 is slidably connected inside the limit block 20, one side of the moving block 21 is fixedly connected to a rack 18, a brush 1 22 is fixedly connected to the upper part of one side of the moving block 21, the half gear 17 is meshed with the rack 18, two brushes 23 are slidably connected inside the brush 1 22, a spring 3 3 is fixedly connected between the two brushes 23, and a spring 2 19 is fixedly connected to the top of the moving block 21.

[0034] Specifically, when cleaning the filter screen 14 in the valve body 1, the motor 15 is driven to rotate the connecting rod 16 and the bevel gear 26, which in turn drives the bevel gear 1 25, the connecting rod 24 and the half gear 17 to rotate. The half gear 17 rotates, so that the rack 18, the moving block 21, the brush 1 22 and the brush 2 23 move downward at the limit of the limit block 20. The moving block 21 moves to compress the spring 2 19. At this time, the rack is driven by the action of the spring 2 19. 18. The moving block 21, the brush 1 22 and the brush 2 23 move upward under the limit of the limit block 20. At this time, the half gear 17 is meshed with the rack 18 again, so as to scrape the dirt off the filter 14. Since the filter 14 is circular, while the brush 2 23 and the brush 1 22 move, the brush 2 23 moves inside the brush 1 22 and compresses the spring 3 3 to adapt to the edge of the filter 14, effectively scraping off the dirt on the surface of the filter 14 to complete the cleaning work.

[0035] Reference Figure 5 and Figure 6 The fixed component includes a rotating ring 6 and a thin shell 7. One side of the thin shell 7 is fixedly connected to the outside of the fixed ring 5. The outside of the rotating ring 6 is rotatably connected to the inside of the fixed ring 5. A plurality of pull ropes 11 are fixedly connected to the outside of the rotating ring 6. One end of the pull rope 11 is fixedly connected to a baffle 13. One side of the baffle 13 is fixedly connected to a plug-in block 12. A spring 10 is sleeved on the outside of the pull rope 11.

[0036] Specifically, when disassembly and inspection are required, the handle on the rotating ring 6 is used to rotate the ring 6 and pull the pull rope 11 to move, thereby pulling the baffle 13 to slide inside the thin shell 7. At this time, the spring 10 is compressed, and the movement of the baffle 13 drives the plug-in block 12 to move until the plug-in block 12 leaves the nut 8 and the screw 9. At this time, the nut 8 is rotated by a tool to disengage the screw 9. At this time, the screw 9 and the nut 8 can be removed, and the disassembly of the connecting pipe 4 and the valve body 1 is completed. When installation is required, the connecting pipe 4 and the valve body 1 are flange-connected. At this time, the handle is released, and under the action of the spring 10, the baffle 13 is pushed to move, thereby driving the plug-in block 12 to be reinserted into the nut 8 and the screw 9. At this time, the installation is completed to avoid the nut 8 and the screw 9 from loosening during use and causing leakage.

[0037] Reference Figure 1 - Figure 3 One end of the spring 10 is fixedly connected to one side of the baffle 13, and the other end of the spring 10 is fixedly connected to the outside of the fixing ring 5. The outside of the baffle 13 is slidably connected to the inside of the thin shell 7. The plug-in block 12 is plugged into the inside of the nut 8. The plug-in block 12 is plugged into the inside of the screw 9. The bottom end of the spring 19 is fixedly connected to the bottom of the valve body 1, and the outside of the plug-in block 12 is slidably connected to the inside of the thin shell 7. A handle is provided on the top of the valve body 1.

[0038] Specifically, one end of the spring 10 is fixedly connected to one side of the baffle 13, and the other end is fixedly connected to the outside of the fixing ring 5. Such a design enables the spring 10 to provide a compressive force when the baffle 13 moves, thereby controlling the movement of the baffle 13 to achieve the locking and unlocking operations of the screw 9 and the nut 8. Specifically, when the spring 10 is compressed, the baffle 13 is pushed under the action of the external force, thereby driving the plug-in block 12 to move, thereby locking the screw 9 and the nut 8; when unlocking is required, the spring 10 is restored to its original state by releasing the baffle 13 or providing sufficient external force, and the baffle 13 also moves accordingly, releasing the plug-in block 12, so that the screw 9 and the nut 8 can be removed. A sliding connection is formed between the outside of the baffle 13 and the inside of the thin shell 7, allowing the baffle 13 to move smoothly inside without causing jamming. The plug-in block 12 is respectively plugged into the inside of the nut 8 and the screw 9, playing a key role in connecting the valve body 1 and the connecting pipe 4, ensuring a stable connection between the two in the working state. The bottom end of the spring 19 is fixedly connected to the inner bottom of the valve body 1, and its function is to provide support and guidance for the movement of the plug-in block 12, ensuring that the plug-in block 12 can be accurately inserted or withdrawn from the inside of the screw 9 and the nut 8 under the action of external force, thereby realizing the connection or disconnection operation. The handle provided on the top of the valve body 1 is convenient for the staff to apply the required force when performing the disassembly operation.

[0039] Working principle: When disassembly and inspection are required, the entire system is driven by rotating the rotating ring 6. As the rotating ring 6 rotates, the pull rope 11 is pulled, which further causes the baffle 13 to move inside the thin shell 7. This action compresses the spring 10 and pushes the baffle 13 forward. During this process, the baffle 13 drives the plug-in block 12 to move until the plug-in block 12 is disengaged from the inside of the nut 8 and the screw 9. At this time, the nut 8 is rotated with the help of a tool to loosen it from the screw 9, thereby separating the connecting pipe 4 from the valve body 1. During assembly, the connecting pipe 4 is connected to the valve body 1 by flange. Subsequently, the handle is released, and the restoring force of the spring 10 pushes the baffle 13 back, thereby driving the plug-in block 12 to be reinserted between the nut 8 and the screw 9, completing the assembly process of the component and effectively preventing leakage caused by loosening of the nut 8 and the screw 9 during use;

[0040] In order to clean the filter 14 in the valve body 1, the driving motor 15 is started, which drives the connecting rod 16 and the bevel gear 26 to rotate, and then the bevel gear 1 25, the connecting rod 24 and the half gear 17 start to rotate. The rotation of the half gear 17 causes the rack 18, the moving block 21, the brush 1 22 and the brush 2 23 to move downward under the restriction of the limit block 20. The movement of the moving block 21 causes the spring 2 19 to be compressed. After that, under the elastic action of the spring 2 19, the above components move upward under the guidance of the limit block 20. At the same time, the half gear 17 and the rack 18 are meshed again, so that the dirt on the surface of the filter 14 is scraped off. Considering the circular characteristics of the filter 14, during the movement of the brush 2 23 and the brush 1 22, the movement of the brush 2 23 inside the brush 1 22 and the compressed spring 3 3 at the same time ensure the effective cleaning of the edge of the filter 14, effectively remove the dirt on the surface of the filter 14, and finally complete the cleaning work.

[0041] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
