Description

Technical Field

[0001] This utility model belongs to the field of valves, specifically, it relates to a bidirectional sealing corrosion-resistant valve with self-cleaning function. Background Technology

[0002] Corrosion-resistant valves are key control components used in pipeline fluid transport systems to regulate, shut off, or change the direction of fluid. They are suitable for transporting corrosive media such as water, steam, gas, strong acid, and strong alkali, and are mainly used in the petroleum and chemical industries [4]. They enhance the corrosion resistance of the valve body through processes such as fluoropolymer lining and rubber lining, and adopt metal and non-metal composite anti-corrosion technology (such as zinc oxide / nickel-based alloy composite coating) to cope with complex working conditions;

[0003] In industries such as chemical, petroleum, and pharmaceutical, pipeline systems frequently transport fluid media containing solid particles, fibers, or corrosive substances. For example, in chemical production, pipelines are often used to transport acid and alkali solutions or organic solvents containing impurities; during oil extraction and transportation, pipelines may contain impurities such as silt and rust. In these scenarios, the sealing components (such as sealing plugs and sealing discs) and rotating components (such as rotating pipes) of traditional valves are prone to wear or jamming due to the adhesion of impurities.

[0004] Specifically, when fluid passes through a valve, impurities may deposit on the inner wall of the rotating pipe or adhere to the surface of the sealing components. Over time, these impurities accumulate, leading to a decrease in the sealing performance of the sealing components and even leakage. Simultaneously, impurities may become stuck between rotating components, affecting the normal opening and closing of the valve. For example, in oil pipelines, silt and sand impurities may become stuck inside the valve's rotating pipe, preventing the valve from closing completely and creating a safety hazard.

[0005] In view of this, this utility model is hereby proposed. Utility Model Content

[0006] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a bidirectional sealing corrosion-resistant valve with self-cleaning function, thus solving the problems mentioned in the background art.

[0009] Optionally, a guide rod is fixedly connected to one side of the inner wall of the valve body, and a guide hole adapted to the guide rod is opened on the opposite side of the connecting ring. A gear is fixedly connected above the rotating ring, and a rod is fixedly connected to the bottom of the inner wall of the valve body. A rack that meshes with the gear is fixedly connected below the rod. After the guide rod is removed from fixing the position of the connecting ring, the gear and the rack will mesh.

[0010] Optionally, an annular groove is provided on the inner wall of the tube facing the valve body, and a straight groove is provided on one side of the annular groove. A push rod is elastically connected in the direction parallel to the straight groove, and a ball is fixedly connected above the push rod. A spiral groove is provided on the circumference of the outer wall of the rotating tube, and the ball slides in the spiral groove. When the push rod is pushed, the ball will push the rotating tube to rotate through the edge of the spiral groove.

[0011] Optionally, a drive mechanism is provided above the valve body, and a rotating rod is fixedly connected below the drive mechanism, passing through the valve body and rotating within the valve body. One end of the rotating rod is fixedly connected to a threaded disc, and a mounting rod is fixedly connected to the top of the inner wall of the valve body. An L-shaped rod is slidably connected inside the mounting rod, and the lower end of the L-shaped rod is rotatably connected to a gear.

[0014] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art. Of course, any product implementing the present invention does not necessarily need to achieve all of the following advantages at the same time:

[0015] By incorporating rotating pipes within the valve body on both sides, and integrating them with internal components such as connecting rings, rotating discs, sealing discs, sealing plugs, cleaning brushes, and water impellers, this valve achieves bidirectional sealing and self-cleaning functions. Specifically, the rotating pipes work in conjunction with other components within the valve body, allowing the cleaning brushes to rotate under the drive of the water impeller during valve opening and closing. The water impeller utilizes the impact force of the water flow to rotate the cleaning brushes, effectively cleaning the inner wall of the rotating pipes and the surface of the sealing plugs. This process automatically removes impurities adhering to the inner wall of the rotating pipes and the sealing plugs, reducing the risk of valve jamming or sealing failure due to excessive impurity accumulation.

Detailed Implementation

[0025] The present invention will now be described in further detail with reference to the accompanying drawings.

[0026] Please see Figure 1-4As shown, this embodiment provides a bidirectional sealing corrosion-resistant valve with self-cleaning function, including a valve body 1. Both sides of the valve body 1 are fixedly connected to a pipe body 2. A rotating pipe 3 is rotatably connected inside the pipe body 2. Two connecting rings 4 are slidably fitted inside the valve body 1. A rotating disk 5 is rotatably connected inside the connecting rings 4. A sealing disk 6 for tightly fitting against the inner wall of the valve body 1 is fixedly connected to one side of the rotating disk 5. A sealing plug 7 located inside the rotating pipe 3 and sealing the rotating rod 19 is fixedly connected to one side of the sealing disk 6. A cleaning brush 8 located inside the rotating pipe 3 is fixedly connected to one end of the sealing plug 7. A water wheel 9 is fixedly connected to the end of the cleaning brush 8.

[0027] By incorporating rotating pipes 3 within the tubes 2 on both sides of the valve body 1, along with internal structures such as connecting rings 4, rotating discs 5, sealing discs 6, sealing plugs 7, cleaning brushes 8, and water wheels 9, the valve achieves bidirectional sealing and self-cleaning functions. This design allows the valve to automatically clean impurities from the inner wall of the rotating pipes 3 and the surface of the sealing plugs 7 during opening and closing, through the cooperation of the cleaning brushes 8 and water wheels 9. This effectively prevents valve jamming and sealing failure caused by impurity accumulation, extending the valve's service life and reducing maintenance costs.

[0028] In this embodiment, a guide rod 10 is fixedly connected to one side of the inner wall of the valve body 1. A guide hole, adapted to the guide rod 10, is provided on the opposite side of the connecting ring 4. A gear 11 is fixedly connected above the rotating ring. A rod 12 is fixedly connected to the bottom of the inner wall of the valve body 1. A rack 13, meshing with the gear 11, is fixedly connected below the rod 12. After the guide rod 10 is no longer fixed to the position of the connecting ring 4, the gear 11 and the rack 13 will mesh. This structure allows the connecting ring 4 to rotate precisely. The cooperation between the guide rod 10 and the guide hole ensures the stability of the connecting ring 4 during sliding, preventing it from shifting or jamming during movement. When the guide rod 10 is no longer fixed to the connecting ring 4, the meshing relationship between the gear 11 and the rack 13 enables the precise rotation of the connecting ring 4, ensuring accurate valve operation during opening and closing.

[0029] In this embodiment, an annular groove 14 is formed on the inner wall of the tube body 2 facing the valve body 1. A straight groove 15 is formed on one side of the annular groove 14. A push rod 16 is elastically connected in the parallel direction of the straight groove 15. A ball 17 is fixedly connected above the push rod 16. A spiral groove 18 is formed on the circumference of the outer wall of the rotating tube 3, and the ball 17 slides in the spiral groove 18. When the push rod 16 is pushed, the ball 17 will push the rotating tube 3 to rotate through the edge of the spiral groove 18. A sliding groove is formed below the straight groove 15. A guide block for the sliding rod in the sliding groove is fixedly connected to one side of the push rod 16. A spring is fixedly connected between one end of the push rod 16 and one side of the inner wall of the straight groove 15.

[0030] Through the cooperation of push rod 16, ball 17, and spiral groove 18, the rotating tube 3 can be driven to rotate by the sliding of ball 17 along spiral groove 18 when push rod 16 moves. This structure not only realizes the automatic rotation of rotating tube 3, but also ensures that push rod 16 can automatically reset through the elastic action of spring, thereby realizing the rotation and stopping of rotating tube 3 during valve opening and closing, providing power support for the cleaning function of cleaning brush 8.

[0031] In this embodiment, a drive mechanism is provided above the valve body 1. A rotating rod 19, passing through the valve body 1 and rotating within it, is fixedly connected below the drive mechanism. A threaded disc 20 is fixedly connected to one end of the rotating rod 19. An mounting rod is fixedly connected to the top of the inner wall of the valve body 1. An L-shaped rod 21 is slidably connected inside the mounting rod. The lower end of the L-shaped rod 21 is rotatably connected to the gear 11, and the lower side of the L-shaped rod 21 is threadedly engaged with the threaded disc 20. The drive mechanism is a stepper motor, and a through hole adapted to the rotating rod 19 is provided above the valve body 1. The rotating rod 19 rotates within the through hole through a sealing ring. The mounting rod serves as a guide, with a rectangular groove through which the L-shaped rod 21 slides on its opposite side. Furthermore, the rotatable connection between the L-shaped rod 21 and the gear 11 can be achieved using bearings, as is common in the prior art.

[0032] The valve is automatically controlled by a stepper motor, making operation simple and precise. The rotation of the rotating rod 19 and the threaded disc 20 drives the L-shaped rod 21 to slide via a threaded connection, thereby adjusting the sealing plug 7 and completing the valve's opening and closing actions. The mounting rod guides the sliding of the L-shaped rod 21, ensuring smooth movement. Furthermore, the rotational connection between the gear 11 and the L-shaped rod 21 utilizes bearings, a technology already in use, further improving the valve's operational reliability and durability.

[0033] In this embodiment, a first planar thread is provided above the threaded disc 20, and a second planar thread that mates with the first planar thread is provided below the slide rod. The first and second planar threads allow the L-shaped rod 21 to slide left and right, and the sealing plug 7 is adjusted during the left and right sliding process.

[0034] In this embodiment, the rod 12 and the mounting rod are installed inside the valve body 1 in an alternating manner. The alternating arrangement of the rod 12 and the mounting rod can avoid motion interference during subsequent movement.

[0035] The sealing disc 6 has diagonal grooves on the side facing the push rod 16. The diagonal grooves reduce the rotation of the rotating disc 5 after it contacts the push rod 16, thus preventing the rotating disc 5 from rotating during the subsequent rotation of the rotating tube 3. This allows the brush to clean the impurities inside the rotating tube 3.

[0036] Working principle: When it is necessary to unlock the valve seal, the stepper motor is started first. The output end of the stepper motor is fixedly connected to the rotating rod 19, and the rotation of the motor will drive the rotating rod 19 to rotate. The rotation of the rotating rod 19 further drives the threaded disc 20 to rotate. The threaded disc 20 is provided with a first planar thread, and the lower end of the L-shaped rod 21 is provided with a second planar thread that mates with it. When the threaded disc 20 rotates, through the engagement of the threads, the L-shaped rod 21 is driven to slide towards the inside of the valve body 1. As the L-shaped rod 21 slides, the part of its lower end connected to the sealing plug 7 will push the sealing plug 7 out of the rotating tube 3.

[0037] During the sliding of the sealing plug 7, the spring connected to the push rod 16 undergoes elastic deformation. The spring force pushes the push rod 16 out of the straight groove 15. A ball 17 is connected to the end of the push rod 16, and the ball 17 is located in the spiral groove 18 on the outer wall of the rotating tube 3. When the push rod 16 is pushed out, the ball 17 slides along the spiral groove 18 and pushes the rotating tube 3 to rotate through the guidance of the spiral groove 18.

[0038] As the L-shaped rod 21 moves the connecting ring 4 away from the rotating tube 3, the connecting ring 4 slides along the guide rod 10. The guide rod 10 is fixed to the inner wall of the valve body 1, and its function is to guide the connecting ring 4 and ensure its smooth sliding. When the connecting ring 4 is completely disengaged from the guide rod 10, the gear 11 above it will mesh with the rack 13 fixed to the bottom of the inner wall of the valve body 1. At this time, if the connecting ring 4 is pulled further away from the rotating tube 3, the gear 11 will rotate 90° under the action of the rack 13. The rotation of the gear 11 will drive the connecting ring 4 to rotate 90°, thereby putting the valve in the open state.

[0039] After the valve is opened, water flows into the valve body 1. The impact force of the water flow acts on the water wheel 9 at the end of the cleaning brush 8, causing the water wheel 9 to rotate. The rotation of the water wheel 9 further drives the cleaning brush 8 and the rotating disc to rotate. During rotation, the cleaning brush 8 contacts the inner wall of the rotating pipe 3, thereby cleaning away the impurities remaining on the inner wall surface. The water flow also washes the surface of the sealing ring, further removing impurities. Through this series of actions, the valve completes its opening and achieves its self-cleaning function.

[0040] When closing the valve, the operation process is the reverse of opening the valve.
