Description

Technical Field

[0001] This utility model relates to a valve ball that is easy to clean. Background Technology

[0002] Chinese Patent No. CN202421519370.1 discloses a ball valve body with helical rifling grooves inside. Fluid flows into the helical rifling grooves on the inner wall of the flow channel. The shape and layout of the helical rifling grooves can improve the flow stability and efficiency of the fluid. After bubbles enter the defoaming channel, they are broken or dispersed into smaller bubbles. The smaller bubbles then enter the downstream defoaming channel and are broken down step by step until the bubbles disappear, thus breaking into smaller fragments or dissolving directly in the liquid. However, if the chemical agent contains particulate or colloidal impurities, these substances may be deposited when passing through the helical rifling grooves, causing impurities to accumulate in the grooves. This not only affects the defoaming effect but may also narrow the flow channel, thus affecting flow control. Therefore, how to clean the inside of the valve ball has become an urgent problem to be solved by those skilled in the art. Summary of the Invention

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a valve ball that is easy to clean, in which the left and right filter screens can be removed from the left and right sides of the upper and lower mounting parts respectively, and the upper and lower mounting parts can be separated to remove the mounting sleeve for cleaning.

[0004] To achieve the above objectives, this utility model provides the following technical solution: It includes a sphere and a valve stem located above the sphere. A flow cavity is provided inside the sphere. It also includes an mounting sleeve, a left filter screen, and a right filter screen. The sphere includes an upper mounting portion and a lower mounting portion. The flow cavity is located between the upper and lower mounting portions. The valve stem is fixedly connected to the upper mounting portion. The mounting sleeve is located within the flow cavity and circumferentially fits against the inner walls of the upper and lower mounting portions. A helical rifling groove is provided inside the mounting sleeve. The left filter screen is detachably connected to the left side of the upper and lower mounting portions, and the right filter screen is detachably connected to the right side of the upper and lower mounting portions.

[0005] The present invention is further configured such that: the mounting sleeve is provided with a plurality of defoaming channels at intervals within the spiral rifling groove, each defoaming channel including an inlet and an outlet, wherein the diameter of the inlet is larger than the diameter of the outlet.

[0006] The present invention is further configured to include a first sealing ring, and positioning posts are integrally formed on both the front and rear sides of the mounting sleeve. The upper mounting part is provided with an upper positioning slot corresponding to each positioning post, and the lower mounting part is provided with a lower positioning slot corresponding to each upper positioning slot. The first sealing ring is located between the positioning post and the upper and lower positioning slots.

[0007] The present invention is further configured such that: the front side of the upper mounting part protrudes downward with a plurality of upper positioning blocks, the rear side of the lower mounting part is provided with a plurality of lower positioning blocks, the upper mounting part is provided with an upper positioning groove corresponding to each lower positioning block, and the lower mounting part is provided with a lower positioning groove corresponding to each upper positioning block.

[0008] The present invention is further configured to include a front sealing section and a rear sealing section located between the upper mounting section and the lower mounting section, wherein the upper and lower sides of the upper mounting section and the lower mounting section are respectively inserted into the upper and lower sides of the front sealing section and the rear sealing section.

[0009] The present invention is further configured such that: the upper mounting part protrudes to the left with an upper connecting block made of rubber, and the lower mounting part protrudes to the left with a lower connecting block made of rubber; the upper connecting block and the lower connecting block have the same shape; the left filter screen is provided with a left connecting slot corresponding to the upper connecting block; the upper connecting block also includes limiting blocks on the front and rear sides; the upper connecting block is provided with a deformation groove; and each limiting block abuts against the left filter screen.

[0010] The present invention is further configured such that: a first insertion hole and a second insertion hole are provided on the left filter screen; a first screw hole is provided on the upper mounting part corresponding to the first insertion hole; and a second screw hole is provided on the lower mounting part corresponding to the second insertion hole.

[0011] The present invention is further configured to include a second sealing ring located between the left filter screen and the upper and lower mounting parts.

[0012] By adopting the above technical solution, 1. because the mounting sleeve is equipped with helical rifling grooves, under the hydrodynamic effect of the fluid, the helical rifling grooves can guide the fluid to flow along a specific path, improving the fluid flow efficiency and velocity. Furthermore, the shape and layout of the helical rifling grooves can enhance the mixing effect and promote bubble breakage; 2. because the left and right filter screens are detachably connected to the left and right sides of the upper and lower mounting parts respectively, after determining the positions of the upper and lower mounting parts, fixing the left and right filter screens indirectly completes the upper... The mounting section and the lower mounting section are assembled and fixed. At the same time, the left and right filter screens can filter the fluid entering the spiral rifling groove of the mounting sleeve and the fluid flowing out of the spiral rifling groove, thereby reducing the occurrence of impurities being mixed into the fluid with the flow of the fluid. If small particles of impurities enter the spiral rifling groove and remain in the mounting sleeve of the ball, the left and right filter screens can be removed to separate the upper and lower mounting sections, and the mounting sleeve can be taken out from the flow cavity, thereby thoroughly and completely cleaning the spiral rifling groove of the mounting sleeve.

[0028] 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.

[0029] like Figures 1-5As shown, this utility model discloses a valve ball that is easy to clean, including a ball 1 and a valve stem 2 located above the ball 1. The ball 1 is provided with a flow cavity 11. By inserting the ball 1 into the valve body, and rotating the valve stem 2 through a switch or other means, the ball 1 can be rotated. When the ball 1 is located on the left and right sides of the flow cavity 11 and connected to the liquid flow channels at both ends of the valve body, the liquid at one end of the valve body can flow to the other end through the flow cavity 11. Reverse rotation of the switch on the valve body causes the valve stem 2 to rotate, thereby displacing the flow cavity 11 on the ball 1 from the liquid flow channels at both ends of the valve body. At this time, the liquid on both sides of the valve body cannot flow, thus achieving... The liquid interception (this is prior art and will not be described in detail here) also includes a mounting sleeve 3, a left filter screen 4, and a right filter screen 5. The sphere 1 includes an upper mounting part 12 and a lower mounting part 13. The flow cavity 11 is located between the upper mounting part 12 and the lower mounting part 13. The valve stem 2 is fixedly connected to the upper mounting part 12. The mounting sleeve 3 is located inside the flow cavity 11 and is circumferentially fitted to the inner walls of the upper mounting part 12 and the lower mounting part 13. The mounting sleeve 3 is provided with a helical rifling groove 31. The left filter screen 4 is detachably connected to the left side of the upper mounting part 12 and the lower mounting part 13 by bolts, clips, etc. The right filter screen 5 is connected to the upper mounting part 12... 2. The right side of the lower mounting part 13 is detachably connected by bolts, clips, etc. 1. Since the mounting sleeve 3 is provided with a helical rifling groove 31, under the hydrodynamic effect of the fluid, the helical rifling groove 31 can guide the fluid to flow along a specific path, improving the fluid flow efficiency and speed. Moreover, the shape and layout of the helical rifling groove 31 can enhance the mixing effect and promote bubble breakage. 2. Since the left filter screen 4 and the right filter screen 5 are detachably connected to the left and right sides of the upper mounting part 12 and the lower mounting part 13, respectively, after the positions of the upper mounting part 12 and the lower mounting part 13 are determined, the left filter screen 4 and the right filter screen 5 are then indirectly fixed. After the upper mounting part 12 and the lower mounting part 13 are assembled and fixed, the left filter screen 4 and the right filter screen 5 can filter the fluid entering the spiral rifling groove 31 of the mounting sleeve 3 and the fluid flowing out of the spiral rifling groove 31, thereby reducing the occurrence of impurities being mixed into the fluid along with the fluid flow. If small particles of impurities enter the spiral rifling groove 31 and remain in the mounting sleeve 3 of the ball 1, the left filter screen 4 and the right filter screen 5 can be removed to separate the upper mounting part 12 and the lower mounting part 13, and the mounting sleeve 3 can be taken out from the flow cavity 11, thereby thoroughly and completely cleaning the spiral rifling groove 31 of the mounting sleeve 3.

[0030] The mounting sleeve 3 is provided with several defoaming channels 32 at intervals within the helical rifling groove 31. Each defoaming channel 32 includes an inlet 321 and an outlet 322. The diameter of the inlet 321 is larger than the diameter of the outlet 322. The fluid flow within the helical rifling groove 31 generates a helical motion trajectory. This motion trajectory pushes the bubbles in the fluid toward each defoaming channel 32. After the bubbles enter the defoaming channel 32 through the inlet 321, they are discharged from the outlet 322. Due to the velocity changes and pressure differences of the fluid within the defoaming channel 32, and because the diameter of the outlet 322 is smaller than the diameter of the inlet 321, it helps to improve the bubble breaking efficiency, while reducing fluid resistance and optimizing the defoaming effect when the fluid passes through.

[0031] This includes a first sealing ring 6 made of rubber. Positioning posts 33 are integrally formed on both the front and rear sides of the mounting sleeve 3. The upper mounting part 12 is provided with upper positioning slots 121 corresponding to each positioning post 33, and the lower mounting part 13 is provided with lower positioning slots 131 corresponding to each upper positioning slot 121. The first sealing ring 6 is located between the positioning posts 33 and the upper and lower positioning slots 121 and 131. 1. During the assembly process, after the mounting sleeve 3 is inserted downwards into the lower mounting part 13, the upper sealing ring 6... Each positioning post 33 will fall into the upper positioning slot 121 and lower positioning slot 131 of the upper mounting part 12 and the lower mounting part 13 respectively. At this time, the upper mounting part 12 is installed above the mounting sleeve 3 to determine the relative position between the mounting sleeve 3 and the upper mounting part 12 and the lower mounting part 13. The mounting sleeve 3 cannot rotate relative to the upper mounting part 12 and the lower mounting part 13. After the left filter screen 4 and the right filter screen 5 are installed, the upper mounting part 12, the lower mounting part 13, the left filter screen 4, and the right filter screen 5 can be assembled and fixed.

[0032] The upper mounting part 12 has several upper positioning blocks 122 protruding downwards from its front side, and the lower mounting part 13 has several lower positioning blocks 132 protruding upwards from its rear side. The upper mounting part 12 has an upper positioning groove 123 corresponding to each lower positioning block 132, and the lower mounting part 13 has a lower positioning groove 133 corresponding to each upper positioning block 122. After the mounting sleeve 3 is inserted into the lower mounting part 13, when the upper mounting part 12 is inserted above the mounting sleeve 3 and the lower mounting part 13, the upper positioning blocks 122 on the upper mounting part 12 will fall into the lower positioning grooves 133 of the lower mounting part 13, and the lower positioning blocks 132 on the lower mounting part 13 will fall into the upper positioning grooves 123 of the upper mounting part 12. This determines the relative position of the upper mounting part 12 and the lower mounting part 13, thus facilitating the subsequent fixing of the two parts.

[0033] Preferably, it also includes a front sealing section 7 and a rear sealing section 8 made of rubber located between the upper mounting part 12 and the lower mounting part 13. The upper and lower sides of the front sealing section 7 and the rear sealing section 8 are respectively inserted into the upper and lower sides of the upper mounting part 12 and the lower mounting part 13. As the upper positioning block 122 enters the lower positioning groove 133 and the lower positioning block 132 enters the upper positioning groove 123, the presence of the front and rear sealing sections 8 can improve the sealing performance between the upper mounting part 12 and the lower mounting part 13 and reduce the occurrence of fluid leakage from the connection position of the upper mounting part 12 and the lower mounting part 13.

[0034] Furthermore, the upper mounting portion 12 protrudes to the left with an upper connecting block 124 made of rubber, and the lower mounting portion 13 protrudes to the left with a lower connecting block 134 made of rubber. The upper connecting block 124 and the lower connecting block 134 have the same shape. The left filter screen 4 is provided with a left connecting slot 41 corresponding to the upper connecting block 124. The upper connecting block 124 also includes limiting blocks 1241 on the front and rear sides. The upper connecting block 124 is provided with a deformation groove 1242. Each limiting block 1241 abuts against the left filter screen 4. Since the left mounting block is made of rubber and includes the limiting blocks 1241 on the front and rear sides, when the left filter screen 4 is inserted into the upper mounting portion 12 and the lower mounting portion 13, the connection slot 41 is formed. When the left side of the filter 4 is in position 3, force is applied to the upper connecting plug 124 so that the limiting block 1241 can move closer to the deformation groove 1242 and forcibly pass over the left connecting slot 41 on the left filter 4. At this time, the force applied to the upper connecting plug 124 is released and each limiting block 1241 will abut against the left filter 4, thereby completing the determination of the relative position of the left filter 4 with the upper mounting part 12 and the lower mounting part 13, which facilitates fixation. When it is necessary to separate the upper connecting plug 124 from the left connecting slot 41, force is applied to each limiting block 1241 so that it moves closer to the deformation groove 1242, and a leftward force is applied to the left filter 4, thereby causing the left filter 4 to separate from the left side of the upper mounting part 12 and the lower mounting part 13.

[0035] The left filter screen 4 is provided with a first insertion hole 42 and a second insertion hole 43. The upper mounting part 12 is provided with a first screw hole 125 corresponding to the first insertion hole 42, and the lower mounting part 13 is provided with a second screw hole 135 corresponding to the second insertion hole 43. By providing the first insertion hole 42, the second insertion hole 43 and the corresponding first screw hole 125 and second screw hole 135, bolts (not shown in the figure) that match the corresponding screw holes can be inserted to more firmly fix the left filter screen 4 between the upper and lower mounting parts 13, ensuring the stability of the structure, and also facilitating disassembly for cleaning or replacement.

[0036] This also includes a second sealing ring 9 made of rubber located between the left filter screen 4 and the upper mounting part 12 and the lower mounting part 13. The design of adding a second sealing ring 9 between the left filter screen 4 and the upper and lower spheres 1 further improves the sealing performance and reduces the possibility of leakage from the connection position between the left filter screen 4 and the upper mounting part 12 and the lower mounting part 13.

[0037] In addition, it is worth noting that the seals inside this valve ball are not limited to the sealing rings installed in the few locations mentioned above; seals can also be installed in more places to improve the sealing performance of the valve ball.

[0038] 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.
