Description

Technical Field

[0001] This utility model belongs to the field of ball valve technology, and in particular relates to a high-stability ball valve with anti-jamming properties. Background Technology

[0002] In the fields of industrial production and fluid control, ball valves are a common type of fluid control device. Their core component is the valve core, which is used to open and close the flow path by rotating the valve core.

[0003] In practical applications, especially in fluid media containing solid particles, impurities, or fluids that are prone to crystallization or scaling, impurities easily accumulate on the outer surface of the valve core. These accumulations can increase friction during valve core rotation, leading to jamming or even complete seizure, severely affecting the normal operation and service life of the valve.

[0004] In addition, when the valve is adjusted to the required opening, the valve stem may rotate unexpectedly under pipeline vibration or external force, causing the valve core position to shift, affecting the stable control of flow, and even causing leakage risk, posing a safety hazard. Utility Model Content

[0005] The purpose of this invention is to provide a high-stability ball valve with anti-jamming capability. In this invention, the ball valve continuously cleans the outer wall of the valve core through the cooperation of an arc-shaped scraper, a sliding block groove, and a first spring, effectively preventing jamming and extending the valve's lifespan. The locking assembly utilizes a gear block, a locking seat, and a second spring to achieve automatic locking, improving valve stability. The design of the lever, guide rod, and magnetic collar makes unlocking convenient, and the nut limit ensures stable unlocking and easy adjustment. The overall design significantly improves the valve's performance and reliability, solving existing technical problems.

[0012] A locking assembly, comprising a gear block and a gear seat, wherein the gear block and the gear seat cooperate with each other;

[0013] The arc-shaped scraper is used to remove impurities attached to the outer wall of the valve core when the valve core rotates to prevent jamming. The gear block and the gear seat are used to lock the valve stem to maintain the valve core's opening and closing state.

[0014] Optionally, the cleaning assembly further includes two grooves formed in the inner wall of the communicating cavity, the two grooves being in the same vertical plane, and a slider being slidably installed inside each of the two grooves. The arc-shaped scraper is located between the two sliders, and both ends of the arc-shaped scraper are fixedly connected to the adjacent sliders respectively.

[0015] Optionally, a first spring is provided inside each of the two slides. One end of the first spring is fixedly connected to the inner wall of the corresponding slide through a spring seat, and the other end is fixedly connected to the adjacent slider through a spring seat. The first spring is used to ensure that the blade of the arc-shaped scraper is in close contact with the outer wall of the valve core to effectively remove impurities.

[0016] Optionally, a bracket is fixedly installed on the top of the fixed cover, and a fixed frame is integrally formed inside the bracket. A pressing cover plate is provided inside the bracket, and the pressing cover plate is fixedly connected to the top of the fixed frame by bolts.

[0017] Optionally, the locking assembly further includes a retaining collar, which is fixedly sleeved on the outer wall of the valve stem. The gear block is fixedly installed at the bottom of the retaining collar, and the gear seat is sleeved on the outer wall of the valve stem and located below the gear block. An abutment block is fixedly installed on the top of the pressing cover plate, and a second spring is sleeved on the outer wall of the valve stem. One end of the second spring is fixedly connected to the bottom of the gear seat through a spring seat, and the other end is fixedly connected to the top of the abutment block through a spring seat. The second spring is used to drive the gear seat and the gear block to continuously engage.

[0018] Optionally, a fixing plate is fixedly installed on one side of the bracket, and two levers are fixedly installed on the outer wall of the gear holder, with the levers located above the fixing plate; guide rods are fixedly embedded on both sides of one of the levers, and the two guide rods slide through the fixing plate to achieve sliding limit of the gear holder.

[0019] Optionally, metal pins are fixedly installed at the bottom of the two dial plates, and a through hole is opened inside the fixed plate. A magnetic collar is fixedly embedded inside the through hole; wherein, the magnetic collar and the metal pins magnetically cooperate to realize the continuous separation of the gear block and the gear seat.

[0020] Optionally, a handwheel is fixedly mounted on the top of the valve stem.

[0021] Optionally, the outer walls of the two guide rods are threaded, and the outer walls of the two guide rods are fitted with limiting nuts; wherein, the limiting nuts cooperate with the fixing plate to provide a limit when the gear holder moves away from the gear block.

[0022] The embodiments of this utility model have the following beneficial effects:

[0023] In this invention, by setting arc-shaped scrapers on both sides of the valve core, the arc-shaped scrapers are installed on the inner wall of the communicating cavity through a slider and groove structure, and equipped with a first spring to provide continuous pressure, ensuring that the blade of the arc-shaped scraper is always in close contact with the arc-shaped outer wall of the valve core; as the valve core rotates, the arc-shaped scraper can continuously scrape the outer wall of the valve core, effectively removing attached impurities and preventing valve core jamming caused by impurity accumulation; this design not only improves the cleaning effect of the valve, but also extends the service life of the valve;

[0024] In this invention, by setting a locking component, including a gear block and a gear seat, as well as a second spring and abutment block that cooperate with it, the automatic locking function of the valve stem is realized. When the valve state is adjusted to the correct position, the gear seat moves upward under the elastic force of the second spring and engages with the gear block to lock it, effectively preventing the valve stem from rotating accidentally, thereby maintaining the stability of the valve core's opening and closing state. This locking mechanism improves the stability and reliability of the valve and avoids unexpected changes in the valve state caused by external factors.

[0025] In this invention, the locking assembly is also equipped with a lever, guide rod, and magnetic collar, making the valve unlocking operation simple and convenient. When the valve needs to be operated again, the operator only needs to press down on the lever, which will cause the gear holder to slide down against the elastic force of the second spring, disengaging the gear holder from the gear block. At the same time, the metal pin at the bottom of the lever can be inserted into the magnetic collar, temporarily fixing the position of the lever and gear holder by magnetic attraction. With the auxiliary limit of the nut, the valve stem can be kept in the unlocked state, facilitating valve adjustment by the operator. After adjustment, releasing the lever again will automatically restore the valve to the locked state.

[0026] In this invention, the design of structures such as a fixed cover, bracket, fixing frame, and pressing cover plate further enhances the stable rotation performance of the valve stem. These structures not only provide stable support and fixation for the valve stem, but also ensure the smoothness and accuracy of the valve stem during rotation.

[0038] To keep the following description of the embodiments of this utility model clear and concise, detailed descriptions of known functions and known components are omitted.

[0039] In one embodiment: Please refer to Figure 1-6 As shown, this embodiment provides a ball valve, which mainly includes a valve body 1, a valve core 3, a valve stem 4, a fixed cover 6, a cleaning component, and a locking component.

[0040] In this embodiment, a communicating cavity 2 is provided inside the valve body 1, and the valve core 3 is sealed inside the valve body 1 to complete the sealing and communication of the communicating cavity 2. A valve stem 4 is fixedly connected to the top of the valve core 3, and the valve core 3 can be rotated by operating the valve stem 4. A handwheel 5 is fixedly installed on the top of the valve stem 4 to facilitate the operator's rotation operation of the valve stem 4.

[0041] In this embodiment, the fixing cover 6 is fixedly installed on the top of the valve body 1 to ensure the stable placement and use of the valve core 3 and the valve stem 4. A bracket 7 is fixedly installed on the top of the fixing cover 6. A fixing frame 8 is integrally formed inside the bracket 7. A pressing cover plate 9 is provided inside the bracket 7. The pressing cover plate 9 is fixedly connected to the top of the fixing frame 8 by bolts to further ensure the stable rotation of the valve stem 4.

[0042] In this embodiment, the cleaning components are disposed on both sides of the valve core 3. Each cleaning component includes an arc-shaped scraper 12, a groove 10, a slider 11, and a first spring 13. Two grooves 10 are formed in the inner wall of the communicating cavity 2, and the two grooves 10 are in the same vertical plane to achieve vertical installation of the arc-shaped scraper 12. The slider 11 is slidably installed inside both grooves 10, and the arc-shaped scraper 12 is located between the two sliders 11, with both ends of the arc-shaped scraper 12 fixedly connected to the adjacent slider 11. A first spring 13 is provided inside both grooves 10. One end of the first spring 13 is fixedly connected to the inner wall of one side of the corresponding groove 10 through a spring seat, and the other end is fixedly connected to one end of the adjacent slider 11 through a spring seat. When the valve core 3 rotates, the arc-shaped scraper 12 is in close contact with the outer wall of the valve core 3 to remove the impurities attached to the outer wall of the valve core 3. The first spring 13 ensures that the blade of the arc-shaped scraper 12 can be in close contact with the arc-shaped outer wall of the valve core 3 to ensure the cleaning effect and reduce the jamming of the valve core 3 during rotation.

[0043] In this embodiment, the locking assembly includes a gear block 16, a gear seat 17, a fixing collar 15, an abutment block 14, a second spring 18, a lever 19, a guide rod 20, a limit nut 21, a metal locking post 22, a fixing plate 23, a through hole 24, and a magnetic collar 25. The fixing collar 15 is fixedly sleeved on the outer wall of the valve stem 4, the gear block 16 is fixedly installed at the bottom of the fixing collar 15, and the gear seat 17 is sleeved on the outer wall of the valve stem 4 and located below the gear block 16. The gear seat 17 engages with the gear block 16. The abutment block 14 is fixedly installed on the top of the pressing cover plate 9, and the second spring 18 is sleeved on the outer wall of the valve stem 4. One end of the second spring 18 is fixedly connected to the bottom of the gear seat 17 through a spring seat, and the other end is fixedly connected to the top of the abutment block 14 through a spring seat. The second spring 18 is used to drive the gear seat 17 to continuously engage with the gear block 16 to maintain the stable opening and closing of the valve core 3.

[0044] In this embodiment, a fixing plate 23 is fixedly installed on one side of the bracket 7, and two lever plates 19 are fixedly installed on the outer wall of the gear holder 17. The lever plates 19 are located above the fixing plate 23. Guide rods 20 are fixedly embedded on both sides of one of the lever plates 19. One end of each of the two guide rods 20 slides through the fixing plate 23 to achieve sliding limit of the gear holder 17.

[0045] This application can be used in the field of ball valve technology, or in other fields applicable to this application.

[0046] In another embodiment: Reference Figure 5 , 6 Anti-jamming and high-stability ball valve, which is applied in the field of ball valve technology;

[0047] In this embodiment, metal pins 22 are fixedly installed at the bottom of both dial plates 19. The metal pins 22 are made of iron. A through hole 24 is opened inside the fixing plate 23. A magnetic collar 25 is fixedly embedded inside the through hole 24. The magnetic collar 25 and the metal pin 22 are magnetically attracted to each other. By inserting the metal pin 22 into the through hole 24 and attracting it to the magnetic collar 25, the gear block 16 and the gear seat 17 can be continuously separated.

[0048] In this embodiment, both guide rods 20 have threads on their outer walls and are fitted with limiting nuts 21 through the threads. The limiting nuts 21 cooperate with the fixing plate 23 and can provide further limiting when the gear holder 17 is away from the gear block 16.

[0049] The usage process and working principle of this utility model technical solution are as follows:

[0050] When it is necessary to open or close the valve, the operator turns the handwheel 5. The handwheel 5 drives the valve stem 4 to rotate, and the valve stem 4 drives the valve core 3 to rotate within the communicating cavity 2 of the valve body 1. The rotation of the valve core 3 opens or closes the communicating cavity 2, thereby controlling the flow of fluid.

[0051] During the rotation of the valve core 3, impurities from the fluid may adhere to its outer wall. At this time, the arc-shaped scrapers 12 positioned on both sides of the valve core 3 can clean the outer wall of the valve core 3. The arc-shaped scrapers 12 are mounted in corresponding grooves 10 on the inner wall of the communicating cavity 2 via sliders 11 at both ends. The first spring 13 within the groove 10 continuously applies pressure, ensuring that the sliders 11 drive the arc-shaped scrapers 12 to always closely adhere to the arc-shaped outer wall of the valve core 3. Because the blades of the two arc-shaped scrapers 12 are in close contact with the outer wall of the valve core 3, as the valve core 3 rotates, the scrapers continuously scrape its surface, peeling off and removing the attached impurities. This process effectively prevents impurities from accumulating on the outer wall of the valve core 3, thus preventing the valve core 3 from jamming. Simultaneously, with the assistance of the corresponding first springs 13, the arc-shaped scrapers 12 maintain a stable cleaning effect.

[0052] After the valve is adjusted to the correct position, the locking assembly automatically locks the valve stem 4. The retaining collar 15 rotates synchronously with the valve stem 4, and the gear block 16 at its bottom corresponds to the tooth groove of the gear seat 17 below. Under the elastic force of the second spring 18, the gear seat 17 moves upward and engages with the gear block 16 to prevent the valve stem 4 from rotating accidentally, thereby maintaining the stable opening and closing state of the valve core 3. At this time, the metal retaining post 22 provides a limit for the movement of the gear seat 17.

[0053] When the valve needs to be operated again, the operator presses down on the lever 19. The lever 19 causes the gear holder 17 to slide downward along the guide rod 20 against the elastic force of the second spring 18, disengaging the gear holder 17 from the gear block 16. Simultaneously, the metal pin 22 at the bottom of the lever 19 inserts downward into the magnetic collar 25 within the fixing plate 23, temporarily fixing the positions of the lever 19 and the gear holder 17 through magnetic attraction. At this time, the valve stem 4 is in the unlocked state. The operator can further adjust the position of the limiting nut 21 on the guide rod 20 to further limit the gear holder 17.

[0054] After turning the handwheel 5 to adjust the valve, the lever 19 is released, the metal pin 22 disengages from the magnetic collar 25, and the second spring 18 can push the gear seat 17 to reset and re-engage the gear block 16. At this time, the valve will return to the locked state.
