Technical Field

[0001] This utility model relates to the field of valve balls, and more particularly to a valve ball with a filtering function. Background Technology

[0002] The valve ball is a key component of a valve. It is typically spherical, with a passageway formed in the center. The ball rotates to control the flow of the valve, thus controlling the flow rate of the medium. The ball is usually made of materials such as stainless steel, copper, or cast iron, which offer good corrosion resistance and mechanical properties.

[0003] In fluid environments containing impurities, it is necessary to set up a filter structure to filter the impurities in the fluid. When the filter structure is located in the middle of the sphere, how to easily remove the filter structure becomes a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a valve ball with a filtering function that can be cleaned by removing the fixed plate and the mounting base so that the filter screen can be removed from the flow channel.

[0005] To achieve the above objectives, this utility model provides the following technical solution: It includes a main body and a filter screen. A flow channel is provided through the interior of the main body. The filter screen is located in the middle of the flow channel and fixed to the main body. A rotating shaft is fixedly installed on the top of the main body. A fixing plate is detachably installed on the top of the main body. The bottom of the rotating shaft is connected to the fixing plate, and the fixing plate is detachably connected to the main body. A mounting post for inserting the filter screen is provided on the fixing plate. A mounting base is detachably installed on the bottom of the main body. The mounting base is inserted into the bottom of the filter screen and detachably connected to the filter screen.

[0006] The present invention is further configured such that: the rotating shaft includes a positioning section with a fixing plate inserted at the bottom, the positioning section is configured as a polygonal prism, and the fixing plate is provided with a positioning groove corresponding to the positioning section.

[0007] The present invention is further configured such that: the main body is provided with a fixing groove for inserting a fixing plate and a circumferentially protruding connecting plate located at the bottom of the fixing groove; the connecting plate abuts against the fixing plate; the connecting plate is provided with a plurality of screw holes in its circumference; and the fixing plate is provided with insertion holes corresponding to each screw hole.

[0008] The present invention is further configured such that: the fixing plate is provided with a plurality of limiting blocks protruding in the circumferential direction, and the body is provided with limiting slots corresponding to each limiting block.

[0009] The present invention is further configured to include a sealing ring made of rubber, the mounting base including a connecting section and a mating section, the connecting section being inserted into the bottom of the body and threadedly engaging with the filter screen, the mating section abutting against the bottom of the body, and the sealing ring being fitted onto the mounting base.

[0010] The present invention is further configured such that: the sealing ring includes a first connecting segment and a second connecting segment, the diameter of the second connecting segment is larger than that of the first connecting segment and is located above the first connecting segment, the body is provided with a sealing groove for the sealing ring to be inserted, and a limiting ring is provided circumferentially at the bottom of the sealing groove to fit the second connecting segment, one end of the limiting ring abutting against the second sealing ring.

[0011] The present invention is further configured to include two screws and a mounting ring sleeved on the bottom circumferential direction of the mating section. Each screw is located on both radial sides of the mating section and is fitted with a mounting ring and a sealing ring to engage with the body thread. The bottom circumferential direction of the mating section is constricted from top to bottom. Each screw includes a head, and each head is flared from top to bottom and abuts against the bottom of the mating section.

[0012] By adopting the above technical solution, since the upper part of the main body is detachably connected to the fixed plate and the lower part is detachably connected to the mounting base, after removing the fixed plate and the mounting base, the filter screen is inserted into the middle of the flow channel through one side opening. After the bottom of the filter screen is detachably connected to the mounting base, the relative position of the filter screen and the main body is determined. Then, the mounting base and the main body, and the fixed plate and the main body are connected. After the filter screen and the mounting base are fixed, the position of the mounting column is fixed. Then, the fixed plate is inserted above the filter screen, which can determine the relative position of the fixed plate and the main body, thus facilitating the connection and fixation of the fixed plate and the main body. At this time, due to the position restriction of the fixed plate and the mounting base, the filter screen cannot rotate in the valve body, thus ensuring stable filtration of fluid impurities in the flow channel of the ball. When it is necessary to remove the filter screen, the mounting base and the filter screen are separated, and then the mounting base and the fixed plate are removed. At this time, the hand or operating tool can be inserted into the flow channel to remove the filter screen from the valve body for cleaning. Attached Figure Description

Detailed Implementation

[0016] 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.

[0017] like Figures 1-8As shown, this utility model discloses a valve ball with a filtering function, including a body 1 and a filter screen 2. A flow channel 11 is provided through the interior of the body 1. The filter screen 2 is located in the middle of the flow channel 11 and is fixed to the body 1 by bolts or other means. A rotating shaft 12 is fixedly installed on the top of the body 1 by welding or other means. The body 1 is rotatably installed in the valve body (not shown in the figure). By rotating the body 1 located in the valve body, the flow channel 11 on the body 1 can be connected to or offset from the channel in the valve body, thereby realizing liquid transmission and cutoff. A fixing plate 3 is detachably installed on the top of the body 1. The bottom of the rotating shaft 12 is connected to the fixing plate 3 by welding or other means, and the fixing plate 3 is detachably connected to the body 1 by snap-fit, sling, or other means. A mounting post 34 for inserting the filter screen 2 is provided on the fixing plate 3. A mounting seat 4 is detachably installed on the bottom of the body 1 by snap-fit, thread, or other means. The mounting seat 4 inserts the bottom of the filter screen 2 and is detachably connected to the filter screen 2 by threads or other means. The body 1 is detachably connected to the fixing plate 3 at the top and to the mounting seat at the bottom. 4. Detachable connection: After removing the fixing plate 3 from the mounting base 4, the filter screen 2 is inserted into the middle of the flow channel 11 through one side opening. After the filter screen 2 is detachably connected to the mounting base 4, the relative position of the filter screen 2 and the body 1 is determined. Then, the mounting base 4 and the body 1, and the fixing plate 3 and the body 1 are connected. After the filter screen 2 and the mounting base 4 are fixed, the position of the mounting post 34 is fixed. Then, the fixing plate 3 is inserted above the filter screen 2 to fix the filter screen 2. The relative position of the fixed plate 3 to the main body 1 is determined, which facilitates the connection and fixation of the fixed plate 3 to the main body 1. At this time, due to the position restriction of the fixed plate 3 and the mounting base 4, the filter screen 2 cannot rotate in the valve body, thus enabling it to stably filter fluid impurities in the flow channel 11 of the ball. When it is necessary to remove the filter screen 2, the mounting base 4 and the fixed plate 3 are removed by separating the mounting base 4 from the filter screen 2. At this time, the hand or operating tool can be inserted into the flow channel 11 to remove the filter screen 2 from the valve body for cleaning.

[0018] It is worth noting that, as a preferred embodiment, during the actual assembly process, a sealing ring can be added between the fixing plate 3 and the mounting base 4 on the fluid channel side and the sphere to reduce the possibility of liquid leakage inside the sphere, which is not specifically shown in the figure.

[0019] The rotating shaft 12 includes a positioning section 13 with a fixing plate 3 inserted at the bottom. The positioning section 13 is a hexagonal prism. The fixing plate 3 is provided with a positioning groove 31 corresponding to the positioning section 13. Since the positioning section 13 is a polygonal prism and the positioning groove 31 is adapted to the shape of the positioning section 13, after the positioning section 13 at the bottom of the rotating shaft 12 is installed into the positioning groove 31, the positioning section 13 cannot rotate relative to the positioning groove 31, thus facilitating the fixed connection between the rotating shaft 12 and the fixing plate 3.

[0020] The main body 1 is provided with a fixing groove 14 for mounting the fixing plate 3 and a circumferentially protruding connecting plate 15 at the bottom of the fixing groove 14. The connecting plate 15 abuts against the fixing plate 3. The connecting plate 15 is provided with a plurality of screw holes 151 in the circumference. The fixing plate 3 is provided with insertion holes 32 corresponding to each screw hole 151. After the rotating shaft 12 and the fixing plate 3 are installed together, the fixing plate 3 is inserted into the fixing groove 14. At this time, the fixing plate 3 cannot move further downward due to the restriction of the connecting plate 15. The mounting column 34 will insert the filter screen 2 to determine the relative position between the filter screen 2 and the fixing plate 3. Then, the bolt (not shown in the figure) that matches the shape of the screw hole 151 is inserted into the insertion hole 32 to complete the thread engagement with the screw hole 151, thereby realizing the connection between the fixing plate 3 connected to the rotating shaft 12 and the main body 1. At this time, since the fixing plate 3 is located above the filter screen 2, the position of the top of the filter screen 2 is restricted and cannot move.

[0021] The fixing plate 3 is provided with a plurality of limiting blocks 33 protruding in the circumference. The body 1 is provided with limiting slots 16 corresponding to each limiting block 33. Due to the presence of the circumferential limiting blocks 33 of the fixing plate 3, when the fixing plate 3 is installed into the fixing groove 14, its circumferential limiting blocks 33 will enter the corresponding limiting slots 16, thereby preventing the fixing plate 3 from rotating in the fixing groove 14, thus facilitating the insertion of the screw 6 into the insertion hole 32 to complete the thread engagement with the screw hole 151.

[0022] In addition, it includes a sealing ring 5 made of rubber. The mounting base 4 includes a connecting section 41 and a mating section 42. The connecting section 41 is inserted into the bottom of the body 1 and threadedly engaged with the filter screen 2. The mating plate abuts against the bottom of the body 1. The sealing ring 5 is fitted onto the mounting base 4. After the filter screen 2 is installed in the middle of the flow channel 11 and the fixing plate 3 is installed, the connecting section 41 of the mounting base 4 is screwed into the bottom of the filter screen 2. The upper and lower sides of the filter screen 2 are respectively restricted by the fixing plate 3 and the mounting base 4 and are stably located in the body 1. This prevents the water flow from impacting the filter screen 2 during the flow of the flow channel 11. By rotating the connecting section 41 of the mounting base 4 in the opposite direction, the mounting base 4 can be separated from the bottom of the filter screen 2. Then, the fixing plate 3 can be removed to take out the filter screen 2.

[0023] The sealing ring 5 includes a first connecting segment 5141 and a second connecting segment 5241. The diameter of the second connecting segment 5241 is larger than that of the first connecting segment 5141 and it is located above the first connecting segment 5141. The body 1 is provided with a sealing groove 17 for the sealing ring 5 to be inserted into. A limiting ring 18 is circumferentially arranged at the bottom of the sealing groove 17, which fits around the second connecting segment 5241. One end of the limiting ring 18 abuts against the second sealing ring 5. Before inserting the mounting base 4, the sealing ring 5 is inserted into the bottom of the body 1. At this time, because the diameter of the second connecting segment 5241 is larger than that of the first connecting segment 5141 and it is located above the first connecting segment 5141, the sealing ring 5 is sealed. During the process of inserting ring 5 into sealing groove 17, the second sealing section first enters the bottom of sealing groove 17 (i.e., the space for the first connecting section 5141 to be placed). Therefore, the second sealing section needs to be squeezed and deformed to pass over the limiting ring 18 to complete the cooperation between sealing ring 5 and sealing groove 17. At this time, due to the effect of limiting ring 18, without the action of external force, the second connecting section 5241 cannot pass over the limiting ring 18 downwards and can be stably located in the body 1. Then, the connecting section 41 of mounting base 4 is screwed into the bottom of filter screen 2. At this time, since sealing ring 5 is fitted around the circumference of mounting section and will not move axially, the sealing performance inside the body 1 is improved, reducing the possibility of water leakage from mounting base 4.

[0024] The system also includes two screws 6 and a mounting ring 7 that fits around the bottom of the mating section 42. Each screw 6 is located on both radial sides of the mating section 42 and is threaded with the mounting ring 7 and sealing ring 5. The bottom of the mating section 42 is constricted from top to bottom. Each screw 6 includes a head 61, which is flared from top to bottom and abuts against the bottom of the mating section 42. With the presence of the mounting ring 7, after the body 1 is installed into the valve body, the mounting ring 7 fits around the mounting seat 4 and is ring-shaped, so the screws 6 will not interfere with the valve body during the rotation of the body 1. The screws 6, with the mounting ring 7 and sealing ring 5, threaded with the body 1, improve the stability of the sealing ring 5 inside the body 1 and the mounting ring 7 around the mounting seat 4. At the same time, the heads 61 of each screw 6 abut against the bottom of the mating section 42, so the mounting seat 4 cannot be rotated before the screws 6 are removed, thus preventing the mounting seat 4 from being rotated arbitrarily without external force and ensuring a stable connection with the filter screen.

[0025] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
