Description

Technical Field

[0001] This utility model relates to the technical field of fluoropolymer-lined floating ball valves, specifically a self-cleaning fluoropolymer-lined floating ball valve. Background Technology

[0002] In industries such as petroleum, chemical, dyeing, pesticide, and acid / alkali production, various highly corrosive media are frequently handled during production processes. These media place extremely high demands on the corrosion resistance of valves. Traditional metal valves are easily corroded by these media, leading to valve damage, leakage, and other problems, seriously affecting production safety and efficiency. Therefore, researchers have designed fluoropolymer-lined floating ball valves for use in conjunction with these media.

[0003] When using a fluoropolymer-lined floating ball valve, the control seat unlocks the valve and rotates it 90°. This causes the floating ball inside the valve to rotate, achieving the valve's opening and closing function. As the floating ball rotates, the liquid transferred to its surface enters the gap between the floating ball and the inside of the fluoropolymer-lined floating ball valve. After using the fluoropolymer-lined floating ball valve to transfer chemicals, the liquid in the gap may solidify, making it difficult to clean. Therefore, a self-cleaning fluoropolymer-lined floating ball valve is needed to address these shortcomings. Utility Model Content

[0004] Technical problems to be solved

[0005] The purpose of this invention is to overcome the shortcomings of existing fluoropolymer-lined floating ball valves, which introduce some liquid into the gaps when the floating ball is rotated, making it difficult to clean after solidification.

[0006] Technical solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a self-cleaning fluoropolymer-lined floating ball valve, comprising a valve body, two flanges fixedly connected to the surface of the valve body, a floating ball body installed inside the valve body, a control seat installed on the surface of the valve body, the control seat connected to the floating ball body, a self-cleaning device on the surface of the floating ball body, and an auxiliary device on the surface of the valve body. The self-cleaning device includes two placement holes, both of which are opened on the arc surface of the floating ball body. Two insertion holes are opened inside the floating ball body, and a placement plate is slidably connected to the surface of the insertion holes. The placement plate is slidably connected to the placement holes. Several bristles are fixedly connected to the surface of the placement plate, and a concealed hole is opened on the surface of the placement plate. Two connecting rods are fixedly connected to the inner wall of the concealed hole, and a snap-fit ​​block is slidably connected to the surface of the two connecting rods. Two embedding holes are opened on the surface of the snap-fit ​​block, and two snap-fit ​​brackets are fixedly connected to the surface of the floating ball body. The snap-fit ​​block snaps into the snap-fit ​​brackets.

[0008] Furthermore, eight extension rods are fixedly connected to the surfaces of several of the bristles, and the eight extension rods are grouped in groups of four. A cleaning ball is fixedly connected to the surface of each of the four extension rods, and the cleaning ball has a hollow structure.

[0009] Furthermore, two wiping blocks are glued to the surface of the placement plate, and both wiping blocks are polyvinyl alcohol sponges.

[0010] Furthermore, springs are fitted onto the surfaces of the two connecting rods, and the two ends of the springs are fixedly connected to the snap-fit ​​block and the placement plate, respectively.

[0011] Furthermore, the auxiliary device includes a connecting frame, which is fixedly connected to the arc surface of the valve body. A slide rail is fixedly connected to the surface of the connecting frame, and an auxiliary plate is slidably connected to the surface of the slide rail. The auxiliary plate is arc-shaped.

[0015] I. This utility model, through its self-cleaning device, enables the brush bristles to contact the gap between the valve body and the floating ball body when the operator adjusts the placement direction of the floating ball body.

[0023] 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.

[0024] like Figure 1-4 As shown, this utility model provides a technical solution: a self-cleaning fluoropolymer-lined floating ball valve, including a valve body 1, two flanges 2 fixedly connected to the surface of the valve body 1, a floating ball body 3 installed inside the valve body 1, a control seat 4 installed on the surface of the valve body 1, the control seat 4 being connected to the floating ball body 3, a self-cleaning device 5 provided on the surface of the floating ball body 3, and an auxiliary device 6 provided on the surface of the valve body 1.

[0025] In this embodiment of the utility model: by installing the self-cleaning device 5 and the floating ball body 3 together, multiple parts are further assembled into a floating ball valve. When opening and closing the floating ball valve, the control seat 4 is pressed to unlock the floating ball body 3. Then, during the rotation, the self-cleaning device 5 contacts the gap between the floating ball body 3 and the valve body 1, achieving a cleaning effect without affecting the rotation of the floating ball body 3. When connecting the valve body 1 and the external pipeline, the auxiliary device 6 can be used to connect the flange 2 of the valve body 1 with the flange 2 of the pipeline, which can help the connection work to proceed quickly.

[0026] like Figure 1-3 As shown, the self-cleaning device 5 includes two placement holes 501, both of which are located on the arc surface of the floating ball body 3. Two insertion holes 502 are located inside the floating ball body 3. A placement plate 504 is slidably connected to the surface of each insertion hole 502, and the placement plate 504 is slidably connected to the placement holes 501. Several bristles 505 are fixedly connected to the surface of the placement plate 504. A concealed insertion hole 509 is provided on the surface of the placement plate 504, and two connecting rods 510 are fixedly connected to the inner wall of the concealed insertion hole 509. A locking block 512 is slidably connected to the surface of each connecting rod 510. Two embedding holes 513 are provided on the surface of the locking block 512. Two locking brackets 503 are fixedly connected to the surface of the floating ball body 3, and the locking block 512 engages with the locking brackets 503. By installing the placement plate 504 on the arc surface of the floating ball body 3, the device automatically cleans the interior of the valve body 1 when the operator rotates the floating ball body 3 in conjunction with the control seat 4, thus cleaning the floating ball body 1. The moving ball body 3 will not experience rotational jamming after prolonged use. Eight extension rods 506 are fixedly connected to the surface of several brush bristles 505. The eight extension rods 506 are grouped in groups of four. Cleaning balls 507 are fixedly connected to the surface of each of the four extension rods 506. The cleaning balls 507 have a hollow structure. Due to the special structure of the cleaning balls 507, they can improve the scraping effect on the solidified matter inside. Two wiping blocks 508 are glued to the surface of the placement plate 504. Both wiping blocks 508 are made of polyvinyl alcohol sponge. The wiping blocks 508 can clean the scraped impurities to the outside of the gap, which is convenient for cleaning when the liquid is flowing. Springs 511 are sleeved on the surface of the two connecting rods 510. The two ends of the springs 511 are fixedly connected to the locking block 512 and the placement plate 504, respectively. The springs 511 can improve the stability of the locking block 512 in the locking frame 503, so that the locking block 512 will not fall into the hidden hole 509 when the floating ball body 3 rotates.

[0027] Working Principle: Before the floating ball valve is put into use, all parts are assembled (the parts used in the self-cleaning device 5 must be made of corrosion-resistant materials). By sliding on the surface of the floating ball body 3, the protruding part of the placement plate 504 can be placed inside the insertion hole 502, thus completing the positioning of the placement plate 504. The placement plate 504 is then fitted together with the placement hole 501. Simultaneously, the locking block 512 is pressed and slid into the recessed hole 509 in conjunction with the embedding hole 513. At this point, the locking block 512 is lower than the surface of the locking bracket 503, allowing the placement plate 504 to fully fit into the placement hole 501. The operator can then release the locking block 512, which will slide upwards under the influence of the spring 511. The locking block 512 then presses against the inside of the locking bracket 503, achieving the locking effect. The addition of the spring 511 helps the locking block 512 automatically achieve the locking effect and improves the stability of the locking, preventing the locking block 512 from sliding downwards. At this point, the self-cleaning device... After the cleaning device 5 is installed, the floating ball valve is assembled by the operator, who installs the floating ball body 3 inside. When transferring chemical liquids through the pipeline, the operator can press the control seat 4 to unlock the floating ball, allowing it to rotate 90°. During this rotation, some chemical liquid is carried into the gap between the floating ball body 3 and the valve body 1. After the chemical liquid transfer is complete, the liquid in the gap will solidify. At this time, the operator will rotate the floating ball body 3 to stop the liquid transfer. At the same time, the bristles 505 on the surface of the placement plate 504 will come into contact with the solidified material in the gap. With the addition of the extension rod 506 and the cleaning ball 507, the contact area with the solidified material is increased, which can scrape off the solidified material and prevent it from accumulating in the gap and affecting the rotation of the floating ball body 3. When the valve is closed by rotation, the scraped solidified material will fall onto the liquid delivery position of the valve body 1. Further, when the liquid is transferred inside the pipeline, the solidified material can be cleaned up along with the liquid transfer.

[0028] like Figure 2 and Figure 4As shown, the auxiliary device 6 includes a connecting frame 601, which is fixedly connected to the arc surface of the valve body 1. A slide rail 602 is fixedly connected to the surface of the connecting frame 601, and an auxiliary plate 603 is slidably connected to the surface of the slide rail 602. The auxiliary plate 603 is arc-shaped. Two slide rods 606 are slidably connected to the surface of the connecting frame 601. A support plate 607 is fixedly connected to the end of each slide rod 606 away from the connecting frame 601. An internal threaded sleeve 609 is rotatably connected to the upper surface of the support plate 607. A screw 610 is threadedly connected to the inner wall of the internal threaded sleeve 609. The screw 610 is rotatably connected to the lower surface of the connecting frame 601. In conjunction with the auxiliary plate 603, it can assist the valve body 1 in... The flange 2 of the auxiliary plate 603 and the flange 2 of the external pipe can quickly achieve the docking effect, which facilitates the connection between the pipes. The arc surface of the auxiliary plate 603 is fixedly connected to two extension plates 604. The surfaces of the two extension plates 604 are rotatably connected with ball bearings 605. The ball bearings 605 are slidably connected to the surface of the slide rail 602. The ball bearings can improve the smoothness of the sliding of the auxiliary plate 603 and further improve the docking efficiency. The lower surface of the support plate 607 is glued with four anti-slip strips 608. The four anti-slip strips 608 are all made of rubber. The addition of anti-slip strips 608 can increase the stability of the support plate 607 and prevent the valve body 1 from shifting when docking with the pipe.

[0029] Working principle: When connecting the valve body 1 to the flange 2 of the external conveying pipeline, the internal threaded sleeve 609 can be rotated first, so that the internal threaded sleeve 609 cooperates with the screw 610 to adjust the position between the support plate 607 and the connecting frame 601. This allows the valve body 1 to be adjusted to a position that facilitates connection with the flange 2 of the conveying pipeline. At the same time, when connecting the flange 2, the auxiliary plate 603 can be slid. When sliding the auxiliary plate 603, the ball bearing 605 reduces the smoothness of sliding, thus aligning the valve body 1 and the flange 2 of the conveying pipeline in a straight line, making it convenient for workers to fix. Meanwhile, the lower surface of the bottom support plate 607 has anti-slip strips 608 that contact the ground, improving the stability during placement and preventing the support plate 607 from moving. After the flange 2 on one side is assembled, the auxiliary plate 603 can still slide to the other side for auxiliary installation, increasing the convenience of connecting the flange 2 of the valve body 1 and the flange 2 of the pipeline.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
