Description

TECHNICAL FIELD

[0001] The utility model relates to valve ball, especially convenient to dismount valve ball. BACKGROUND

[0002] Valve ball is one of the core components of ball valve (also called as spherical valve), and the ball valve is a kind of valve that controls fluid flow by rotating ball, and its characteristics are compact structure, good sealing performance, convenient operation and quick opening and closing, the ball in the ball valve usually has a through hole, when the hole is aligned with the pipeline, fluid can pass freely, and when the ball is rotated 90 degrees to make the hole perpendicular to the pipeline direction, fluid flow is prevented, and the rotation of the ball is realized by rotating the valve stem.

[0003] During assembly, since there is only one embedding groove on the valve ball, when the valve stem is assembled with the valve ball, the embedding block on the valve stem is embedded into the embedding groove to realize the fixation of the embedding block and the ball.

[0004] Therefore, how to quickly assemble the embedding block of the valve stem and stably connect the valve stem and the ball becomes a problem to be solved by the person skilled in the art. SUMMARY

[0005] In view of the deficiencies in the prior art, the utility model aims at providing a kind of valve ball that is convenient to dismount by embedding the positioning plug of the bottom of valve stem into corresponding positioning slot and then rotating baffle downward, so that baffle can be in contact with positioning plug, and valve stem and ball are stably connected.

[0006] To achieve the above object, the utility model provides the following technical scheme: including ball and valve stem, the valve stem is located above the ball and can be detachably connected with the ball, the ball is provided with fluid passage along left-right direction, the bottom of the valve stem is provided with two positioning plugs made of material prone to deformation, each positioning plug is symmetrically arranged, the ball is provided with positioning slot corresponding to each positioning plug, the ball is rotatably provided with baffle on each positioning slot, and each baffle is pressed above corresponding positioning plug and can be detachably connected with corresponding positioning plug.

[0007] The utility model is further provided as follows: each baffle is provided with positioning column downward, and each positioning plug is provided with positioning slot corresponding to positioning column.

[0008] The utility model is further provided as follows: the diameter of the bottom of each positioning column is less than the diameter of corresponding positioning slot.

[0009] The utility model is further provided as follows: each baffle is provided with first magnet, and the ball is provided with second magnet in each positioning slot, which is attracted to corresponding first magnet.

[0010] The present invention is further configured such that: the sphere is provided with a plurality of mating slots and mating plates rotatably mounted on the corresponding mating slots for each positioning block, and each of the mating slots and the positioning slots have the same shape and size, and each of the mating plates and the baffles have the same shape and size.

[0011] The present invention is further configured to include two filter screens. The sphere includes an inlet located on the left side of the fluid channel and an outlet located on the right side of the fluid channel. Each filter screen is located at the inlet and the outlet respectively and is detachably connected to the sphere.

[0012] The present invention is further configured such that: the sphere is integrally formed with an installation ring at the inlet, the installation ring is provided with an installation groove for inserting the filter screen, the installation ring is provided with a disassembly section abutting the filter screen at the rear side of the filter screen, and the filter screen is detachably connected to the disassembly section.

[0013] The present invention is further configured such that: the mounting ring is provided with a plurality of limiting blocks protruding in the circumferential direction; the filter screen is made of a material that is prone to deformation and each limiting block is provided with a limiting slot.

[0014] By adopting the above technical solution, before the positioning block at the bottom of the valve stem is inserted into the positioning slot of the ball, the baffle needs to be rotated upwards so that the positioning block can enter the positioning slot more smoothly. At this time, the positioning block of the valve stem cannot rotate relative to the ball, thus preventing the valve stem from rotating relative to the ball. Then, the baffle is rotated downwards so that it is positioned above the positioning block. At this time, the baffle can abut against the positioning block, preventing the positioning block from moving upwards over the baffle without external force. This prevents the valve stem from moving up and down relative to the ball, allowing the valve stem to quickly determine its relative position with the ball and be stably connected to the ball.

[0025] 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.

[0026] like Figures 1-6As shown, this utility model discloses a valve ball that is easy to assemble and disassemble, including a ball 1 and a valve stem 2. The valve stem 2 is located above the ball 1 and is detachably connected to the ball 1 by means of threads, welding, etc. The ball 1 has a fluid channel 11 extending through it in the left-right direction. The valve body (not shown in the figure) has an inlet and an outlet corresponding to the fluid channel 11. Therefore, the pipes located on both sides of the valve body are connected to the inlet and the outlet, respectively. When it is necessary to make the liquid at the inlet flow towards the outlet, the valve stem 2 needs to be rotated to open the fluid channel 11. The left and right sides of the valve are connected to the inlet and outlet respectively, allowing the liquid at the inlet to flow towards the outlet through the fluid channel 11. When it is necessary to block the flow of liquid from the inlet to the outlet, the valve stem 2 is rotated, causing the fluid channel 11 on the ball 1 to be misaligned with the inlet and outlet. At this time, the liquid at the inlet cannot enter the fluid channel 11 and cannot flow towards the outlet (this is prior art and will not be described in detail here). The bottom of the valve stem 2 is provided with two positioning blocks 21 made of a material that is prone to deformation. The blocks 21 are symmetrically arranged. Each sphere 1 has a positioning slot 19 corresponding to each positioning block 21. A baffle 12 is rotatably mounted on each positioning slot 19 of the sphere 1. Each baffle 12 presses against the corresponding positioning block 21 and is detachably connected to the corresponding positioning block 21 via magnetic attraction or other means. Before inserting the positioning block 21 at the bottom of the valve stem 2 into the positioning slot 19 of the sphere 1, the baffle 12 needs to be rotated upwards to allow the positioning block 21 to enter the positioning slot 19 more smoothly. At this point, the valve stem... The positioning block 21 of valve stem 2 cannot rotate relative to the ball 1, thus preventing the valve stem 2 from rotating relative to the ball 1. Then, the baffle 12 is rotated downwards so that it is positioned above the positioning block 21. At this time, the baffle 12 can abut against the positioning block 21, preventing the positioning block 21 from moving upwards over the baffle 12 without external force. This prevents the valve stem 2 from moving up and down relative to the ball 1, allowing the valve stem 2 to quickly determine its relative position with the ball 1 and be stably connected to it.

[0027] Each of the baffles 12 is provided with a downward-facing positioning post 121, and each of the positioning blocks 21 is provided with a positioning groove 211 corresponding to the positioning post 121. After the positioning block 21 enters the corresponding positioning slot 19, rotating the baffle 12 downwards will allow the positioning post 121 on the baffle 12 to enter the positioning groove 211 of the positioning block 21. At this time, the baffle 12 can be stably connected to the positioning block 21 due to the presence of the positioning post 121. Thus, after the baffle 12 is above the positioning block 21, it will not be subject to external force and will not be arbitrarily flipped or shaken, thus maintaining a stable connection with the positioning block 21. Rotating the baffle 12 upwards can cause the positioning post 121 on the baffle 12 to separate from the corresponding positioning groove 211, thereby causing the valve stem 2 to move upwards and causing the positioning block 21 on the valve stem 2 to separate from the corresponding positioning slot 19.

[0028] Preferably, the bottom diameter of each positioning post 121 is smaller than the diameter of the corresponding positioning groove 211. Since the bottom diameter of the positioning post 121 is smaller than the diameter of the positioning groove 211, after the positioning block 21 is inserted into the positioning slot 19, when the baffle 12 is rotated downwards, the bottom of the positioning post 121 on the baffle 12 will first enter the positioning groove 211 of the positioning block 21. And since the bottom diameter of the positioning post 121 is smaller than the diameter of the corresponding positioning groove 211, after the baffle 12 is rotated downwards, the positioning post 121 can be more smoothly aligned with the positioning groove 211 and then inserted into the positioning groove 211.

[0029] Preferably, each of the baffles 12 is provided with a first magnet 122, and each of the spheres 1 located in each positioning slot 19 is provided with a second magnet 13 that attracts the corresponding first magnet 122. Since each baffle 12 is provided with a first magnet 122, after the baffle 12 is rotated downwards so that the positioning post 121 on the baffle 12 is inserted into the positioning slot 211, the first magnet 122 on the baffle 12 located above the positioning block 21 will attract the second magnet 13 on the sphere 1, thereby making the baffle 12 more stably positioned above the positioning block 21. When it is necessary to separate the valve stem 2 from the sphere 1, the baffle 12 must first be bent so that the positioning post 121 on the baffle 12 can be separated from the positioning slot 211. At this time, the first magnet 122 will be misaligned with the second magnet 13, thereby causing the baffle 12 to flip upwards, thereby separating the positioning block 21 on the valve stem 2 from the positioning slot 19 and realizing the separation of the valve stem 2 from the sphere 1.

[0030] Preferably, the ball 1 is further provided with a plurality of mating slots 14 and mating plates 15 rotatably mounted on the corresponding mating slots 14 for each positioning block 21. Each mating slot 14 has the same shape and size as the positioning slot 19, and each mating plate 15 has the same shape and size as the baffle 12. Since the ball 1 is also provided with mating slots 14 of the same shape and size as the positioning slot 19 and mating plates 15 of the same shape and size as the baffle 12 and rotatably connected to the ball 1 for each positioning block 21, the positioning blocks 21 on the valve stem 2 can be inserted into the positioning slots 14 during the downward movement of the valve stem 2 relative to the ball 1. The positioning slot 19 can also enter the mating slot 14 to complete the fixed connection between the valve stem 2 and the ball 1. In addition, if the positioning slot 19 of the ball 1 is worn during use and the positioning block 21 moves inside the positioning slot 19, the baffle 12 can be rotated to remove the positioning block 21 from the positioning slot 19. Then, the mating plate 15 can be rotated upwards to insert the positioning block 21 into the mating slot 14 to complete the connection between the valve stem 2 and the ball 1. Therefore, the setting of the mating slot 14 and the mating plate 15 can provide a new position for the valve stem 2 to be installed in the ball 1, thereby extending the service life of the ball 1.

[0031] In addition, two filter screens 3 are included. The ball 1 includes an inlet 16 located on the left side of the fluid channel 11 and an outlet 17 located on the right side of the fluid channel 11. Each filter screen 3 is located at the inlet 16 and the outlet 17 respectively and is detachably connected to the ball 1 by bolts, clips, or other means. Since the filter screens 3 are located at the inlet 16 and the outlet 17 of the ball 1 respectively, after the ball 1 is installed into the valve body, the liquid flowing in from the inlet of the valve body needs to pass through the filter screen 3 at the inlet 16 first. The liquid enters the fluid channel 11 and then passes through the filter screen 3 located at the outlet 17 before it can flow out of the outlet. Therefore, before entering the fluid channel 11, the liquid flowing through the sphere 1 is first restricted by the filter screen 3 located at the left inlet 16, so that the particulate impurities in the liquid can be intercepted on the left side of the filter screen 3. If there are still impurities in the liquid in the fluid channel 11, they will be intercepted by the filter screen 3 when flowing towards the outlet 17 and will not be able to pass through the filter screen 3 to flow out of the outlet 17.

[0032] The sphere 1 is integrally formed with an installation ring 18 at the inlet 16. The installation ring 18 has an installation groove 181 for inserting the filter screen 3. The installation ring 18 has a disassembly section 182 on the rear side of the filter screen 3, which abuts against the filter screen 3. The filter screen 3 and the disassembly section 182 are detachably connected by fastening, bolts, or other means. Since the rear side of the filter screen 3 abuts against the disassembly section 182 of the installation ring 18 on the sphere 1, when the filter screen 3 is inserted into the sphere 1 at the inlet 16, the filter screen 3 will abut against the disassembly section 182. This provides guidance for determining the relative position of the filter screen 3 and the sphere 1, thus facilitating the fixing of the filter screen 3 and the sphere 1.

[0033] Preferably, the mounting ring 18 is circumferentially provided with a plurality of limiting blocks 183 made of a material that is easily deformable, such as rubber. The filter screen 3 is made of a material that is easily deformable, such as rubber, and each limiting block 183 is provided with a limiting slot 31. Since the filter screen 3 is made of a material that is easily deformable, when the filter screen 3 is installed on the left side of the mounting ring 18, the part of the filter screen 3 located on the right side of the limiting slot 31 needs to be forced past the limiting blocks 183 so that each limiting block 183 can enter the corresponding limiting slot 31. Once inside the corresponding limiting slot 31, the filter screen 3 is restricted by the limiting blocks 183 and cannot rotate or move relative to the mounting ring 18, thus allowing the filter screen 3 to be stably connected to the mounting ring 18, i.e., the filter screen 3 is stably located on the ball 1. When it is necessary to remove the filter screen 3 from the ball 1 for cleaning, a force is applied to each limiting block 183 away from the side of the filter screen 3 to pull the filter screen 3, thereby separating the limiting slot 31 on the filter screen 3 from the corresponding limiting block 183 and removing the filter screen 3 from the ball 1.

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.
