Description

Technical Field

[0001] The present application relates to the technical field of valves, and in particular to a ball valve capable of preventing a valve handle from getting stuck. Background Art

[0002] High-pressure ball valve is an important control equipment widely used in petroleum, chemical, natural gas, water treatment and other industries. It is mainly used to control the flow and cutoff of media in high-pressure pipelines, and also has the functions of regulating flow and protecting pipeline systems.

[0003] At present, a general high-pressure ball valve includes a valve body, a valve ball and a valve stem. The valve ball is arranged in the valve body, and the valve is opened and closed by the rotation of the valve ball. The valve stem is used to drive the valve ball to rotate. The valve stem passes through the valve body and is connected to the valve ball.

[0004] However, in actual production, very high requirements are placed on the verticality between the valve stem and the valve ball. Once a deviation occurs during use, the ball valve is prone to getting stuck. Summary of the invention

[0005] In order to improve the rotation stability of the ball valve, the present application provides a ball valve that prevents the valve handle from getting stuck.

[0006] The present application provides a ball valve for preventing the valve handle from getting stuck, which adopts the following technical solution:

[0007] A ball valve for preventing a valve handle from getting stuck, comprising:

[0008] A valve body, wherein the valve body is provided with a mounting cavity connected to the interior of the valve body;

[0009] A ball body, rotatably connected to the valve body;

[0010] A valve stem, one end of which passes through the mounting cavity of the valve body and is slidably inserted into the connecting groove on the ball;

[0011] There are two sealed cavities on the inner wall of the installation cavity, and bearings are arranged in the sealed cavities. The bearings include:

[0012] An inner ring, the inner wall of which is fixedly connected to the side wall of the valve stem;

[0013] An outer ring, which is hollow inside and has an outer wall fixedly connected to the valve body;

[0014] A plurality of balls are provided, and the plurality of balls are evenly arranged around the axis of the inner ring, and the balls are located between the inner ring and the outer ring;

[0015] An oil adding assembly, disposed in the outer ring and used for adding lubricating oil to the ball bearings;

[0016] A positioning component, with two ends respectively connected to the valve body and the ball, and used to limit the opening of the oil filling component.

[0017] By adopting the above technical solution and the design of the bearing, the friction resistance between the valve stem and the valve body during the rotation process is effectively reduced, thereby avoiding the problem of jamming. During the rotation of the valve stem, the oil adding component adds lubricating oil to the ball bearing, thereby ensuring that the bearing always maintains a good lubrication state during long-term use, thereby further avoiding the problem of jamming.

[0018] Through the rotation of the ball, when the ball valve is opened, the positioning assembly dislocates the ball and the oil filling assembly, so that the ball cannot open the oil filling assembly, avoiding lubricating oil leakage, thereby improving the rotation stability of the ball valve.

[0019] Optionally, an oil filling hole is provided on a side of the outer ring close to the inner ring, and the oil filling assembly includes:

[0020] A sliding rod, slidably connected in the oil filling hole and extending out of the oil filling hole;

[0021] A sealing cover, fixedly mounted on an end of the slide rod away from the inner ring, wherein the diameter of the sealing cover is larger than the diameter of the oil filling hole;

[0022] The compression spring has two ends fixedly connected to the inner wall of the outer ring and the sealing cover respectively. In the initial state, the compression spring is in an extended state.

[0023] By adopting the above technical solution, during the rotation process, the ball squeezes the slide rod, the slide rod moves along the oil filling hole, the slide rod drives the sealing cover to move, the oil filling hole is opened, the lubricating oil flows out, and is smeared on the ball;

[0024] At the same time, the slide rod squeezes the compression spring, the compression amount of the compression spring increases, and the elastic force is accumulated. When the ball rotates away, the slide rod is reset under the elastic force of the compression spring, and the sealing cover re-seals the oil filling hole for effective sealing, thereby improving the safety of the ball valve.

[0025] Optionally, a plurality of the oil filling holes are provided, and the plurality of the oil filling holes are evenly arranged around the axial direction of the outer ring, and a plurality of the oil filling assemblies are provided, and the plurality of the oil filling assemblies correspond one-to-one to the plurality of the oil filling holes.

[0026] By adopting the above technical solution, it can be ensured that the balls can obtain sufficient lubricating oil at all positions, thereby effectively reducing the friction between the balls and the outer ring, and thus easily improving the service life and operating stability of the bearing.

[0027] Optionally, one end of the sliding rod away from the compression spring is fixedly connected to a rotating ball.

[0028] By adopting the above technical solution, during the rotation process, the ball contacts the rotating ball, which reduces the contact area of ​​the ball and reduces the wear of the ball, thereby making the bearing less prone to wear.

[0029] Optionally, a rotation groove is provided in the valve body, and the positioning assembly includes:

[0030] Positioning unit, comprising:

[0031] A connecting rod, one end of which is fixedly connected to a side of the ball away from the valve stem, and the other end of which is rotatably connected to the valve body;

[0032] A valve seat, fixedly connected to the connecting rod;

[0033] The limiting block is in a truncated cone shape and is fixedly connected to the valve seat;

[0034] A connecting column, one end of which is fixedly connected to the top surface of the limit block;

[0035] A pressing block is in a truncated cone shape and is arranged in the same direction as the limiting block, and the pressing block is fixedly connected to an end of the connecting column away from the limiting block;

[0036] There are two clamping blocks, which are arranged opposite to each other and are both slidably connected in the rotating groove;

[0037] There are two return springs, the two return springs correspond to the two clamping blocks one by one, the two ends of the return spring are respectively fixedly connected to the clamping blocks and the inner wall of the rotating groove, and in the initial state, the return spring is in an extended state;

[0038] The resetting portion is disposed on the positioning portion and is used to drive the positioning portion to reset.

[0039] By adopting the above technical solution, during the opening process of the ball valve, the ball drives the connecting rod to rotate, the connecting rod drives the valve seat to rotate, the valve seat drives the limit block to move, the limit block drives the connecting column to move, and the connecting column drives the clamping block to move; when the ball valve is opened, the clamping block slides along the inclined surface of the clamping block to the bottom surface of the clamping block, clamping the clamping block to prevent the ball from excessive rotation or deviating from the predetermined position, thereby ensuring that the ball and the rotating ball are misaligned, thereby improving stability.

[0040] Optionally, the resetting unit includes:

[0041] The sliding block is in a truncated cone shape and is arranged in a direction opposite to the limiting block, and the sliding block is slidably arranged on the connecting column;

[0042] The connecting spring has two ends fixedly connected to the sliding block and the limiting block respectively. In the initial state, the connecting spring is in a compressed state.

[0043] By adopting the above technical solution, when the ball valve needs to be closed, the ball body is continuously rotated, the clamping block slides to the inclined surface of the sliding block, and then rotated in the opposite direction. Under the action of the clamping force, the clamping block drives the sliding block to move in the direction of the clamping block, the sliding block abuts against the clamping block, and the clamping block slides to the inclined surface of the clamping block again, thereby sliding away from the clamping block.

[0044] At the same time, the sliding block stretches the connecting spring, and the connecting spring accumulates elastic force. When the clamping block is separated from the sliding block, the sliding block is reset under the elastic force of the connecting spring, so that the ball valve is easy to rotate and reset, thereby improving the rotation efficiency.

[0045] Optionally, a U-shaped sealing ring is fixedly connected in the installation cavity, and the U-shaped sealing ring is sleeved on the valve stem.

[0046] By adopting the above technical solution, since the U-shaped sealing ring has a certain elasticity and adaptability, it can maintain a tight fit as the valve stem moves up and down, and will not loosen or produce gaps due to the movement of the valve stem. It can effectively improve the sealing performance between the valve stem and the installation cavity, thereby ensuring the normal operation and service life of the ball valve.

[0047] Optionally, two reinforced sealing rings are provided in the valve body, the two reinforced sealing rings are fixedly connected to the two ends of the valve body channel respectively, and the reinforced sealing rings abut against the ball.

[0048] By adopting the above technical solution, since the two reinforced sealing rings are located at both ends of the valve body channel, they can jointly withstand the pressure of the fluid and make adaptive adjustments according to changes in pressure, so that the valve can maintain stable sealing performance under different pressure environments.

[0049] Optionally, one end of the valve stem away from the sphere is fixedly connected with a handle.

[0050] By adopting the above technical solution, the design of the handle enhances the force application point, making it easier for the operator to provide a larger torque when the valve is closed or opened, thereby easily ensuring reliable operation of the valve.

[0051] In summary, the present application includes at least one of the following beneficial technical effects:

[0052] By providing a bearing structure with a ball between the valve stem and the valve body, the friction of the valve stem during rotation can be significantly reduced, thereby effectively avoiding the ball valve jamming caused by the verticality deviation between the valve stem and the valve ball;

[0053] The design of the oil filling assembly allows the ball to be continuously lubricated, further reducing the friction coefficient, extending the service life of the ball valve and improving operational stability;

[0054] The setting of the positioning component can limit the opening of the oil filling component when the ball valve is closed, ensuring that the lubricating oil will not leak and ensuring the sealing and reliability of the system. BRIEF DESCRIPTION OF THE DRAWINGS

The end of the valve stem 3 away from the ball 2 is fixedly connected to a handle 31, and the handle 31 is vertically arranged with the valve stem 3.

[0066] Reference Figure 2 and Figure 3 Two sealing cavities are provided on the inner wall of the installation cavity 11, and the two sealing cavities are arranged along the axial direction of the valve stem 3. A bearing 14 is arranged in the sealing cavity, and the bearing 14 includes an inner ring 141, an outer ring 142 and a ball 143. The inner wall of the inner ring 141 is fixedly connected to the side wall of the valve stem 3; the outer ring 142 is hollow inside, and the outer wall is fixedly connected to the valve body 1, and lubricating oil is stored in the outer ring 142; a plurality of balls 143 are provided, and the plurality of balls 143 are evenly arranged around the axis of the inner ring 141, and the balls 143 are located between the inner ring 141 and the outer ring 142, and are rotatably connected to the inner ring 141.

[0067] Reference Figure 2 and Figure 3 The oil adding component 4 is arranged in the outer ring 142 and is used to add lubricating oil to the ball 143; the two ends of the positioning component 5 are respectively connected to the valve body 1 and the ball 2, and are used to limit the opening of the oil adding component 4.

[0068] When in use, the handle 31 is rotated, the handle 31 drives the valve stem 3 to rotate, the valve stem 3 drives the ball 2 to rotate, during the rotation process, the valve stem 3 drives the inner ring 141 to rotate, the inner ring 141 drives the ball 143 to rotate, during the rotation process of the ball 143, the oil adding component 4 adds oil to the ball 143 to increase lubricity, effectively reducing the friction resistance between the valve stem 3 and the valve body 1 during the rotation process, and avoiding the problem of jamming;

[0069] When the ball valve is fully opened, the positioning assembly 5 limits the position of the inner ring 141, and displaces the ball 143 and the oil filling assembly 4, so that the ball 143 cannot open the oil filling assembly 4, thereby effectively preventing continuous leakage of lubricating oil and further improving the rotation stability of the ball valve.

[0070] Reference Figure 3 A side of the outer ring 142 close to the inner ring 141 is provided with an oil filling hole 1421, and a plurality of oil filling holes 1421 are provided, and the plurality of oil filling holes 1421 are evenly arranged around the axial direction of the outer ring 142, and a plurality of oil filling components 4 are provided, and the plurality of oil filling components 4 correspond one to one to the plurality of oil filling holes 1421.

[0071] Reference Figure 3The oil filling assembly 4 includes a slide bar 41, a sealing cover 42 and a compression spring 43. The slide bar 41 is slidably connected in the oil filling hole 1421 and extends out of the oil filling hole 1421.

The diameter of the sealing cover 42 is larger than the diameter of the oil filling hole 1421. The two ends of the compression spring 43 are respectively fixedly connected to the inner wall of the outer ring 142 and the sealing cover 42. In the initial state, the compression spring 43 is in an extended state.

[0073] When in use, the valve stem 3 drives the inner ring 141 to rotate, and the inner ring 141 drives the ball 143 to rotate. During the rotation process, the ball 143 squeezes the rotating ball 32, and the rotating ball 32 pushes the slide bar 41 to move along the oil filling hole 1421. The slide bar 41 drives the sealing cover 42 to move, open the oil filling hole 1421, and the lubricating oil flows to the ball 143;

[0074] At the same time, the sealing cover 42 squeezes the compression spring 43 to accumulate elastic force. When the ball 143 rotates away, the slide rod 41 is reset under the elastic force of the compression spring 43, and the sealing cover 42 re-blocks the oil filling hole 1421 for effective sealing, thereby improving the safety of the ball valve.

[0075] Reference Figure 2 , Figure 4 and Figure 5 A rotation groove 15 is provided on the bottom end of the valve body 1. The positioning assembly 5 includes a positioning portion 51 and a reset portion 52. The positioning portion 51 includes a connecting rod 511, a valve seat 512, a limit block 513, a connecting column 514, a clamping block 515, a clamping block 516 and a reset spring 517. One end of the connecting rod 511 is fixedly connected to the side of the ball 2 away from the valve stem 3, and the other end is rotatably connected to the valve body 1.

[0076] Reference Figure 5 The valve seat 512 is fixedly connected to the connecting rod 511 and is located in the rotating groove 15. The limit block 513 is truncated cone-shaped, and its bottom surface is fixedly connected to the valve seat 512. One end of the connecting column 514 is fixedly connected to the top surface of the limit block 513, and the pressing block 515 is truncated cone-shaped and is arranged in the same direction as the limit block 513. The bottom surface of the pressing block 515 is fixedly connected to the end of the connecting column 514 away from the limit block 513.

[0077] Reference Figure 5Two clearance grooves 16 are provided on the side wall of the rotating groove 15, and the two clearance grooves 16 are arranged opposite to each other. Two clamping blocks 516 are provided, and the clamping blocks 516 are in a triangular prism shape and are slidably connected in the clearance grooves 16. Two return springs 517 are provided, and the two return springs 517 correspond to the two clamping blocks 516 one by one. The two ends of the return spring 517 are fixedly connected to the clamping blocks 516 and the bottom of the clearance groove 16 respectively. In the initial state, the return spring 517 is in an extended state.

[0078] Reference Figure 5 The reset portion 52 includes a sliding block 521 and a connecting spring 522.

The sliding block 521 is slidably penetrated on the connecting column 514; the two ends of the connecting spring 522 are fixedly connected to the sliding block 521 and the limit block 513 respectively. In the initial state, the connecting spring 522 is in a compressed state.

[0079] When in use, during the process of opening the ball valve, the ball 2 drives the connecting rod 511 to rotate, the connecting rod 511 drives the valve seat 512 to rotate, the valve seat 512 drives the limit block 513 to move, the limit block 513 drives the connecting column 514 to move, and the connecting column 514 drives the clamping block 515 to move; when the ball valve is opened, the clamping block 516 slides along the inclined surface of the clamping block 515 to the bottom surface of the clamping block 515, clamping the clamping block 515 to prevent the ball 2 from excessive rotation or deviation from the predetermined position, and ensuring that the ball 143 is misaligned with the rotating ball 32;

[0080] When the ball valve needs to be closed, the ball 32 continues to rotate, the clamping block 516 slides to the inclined surface of the sliding block 521, and then rotates in the opposite direction. Under the action of the clamping force, the clamping block 516 drives the sliding block 521 to move in the direction of the clamping block 515, the sliding block 521 abuts against the clamping block 515, and the clamping block 516 slides to the inclined surface of the clamping block 515 again, thereby sliding away from the clamping block 515, making it easy to rotate and reset the ball valve, thereby improving the rotation efficiency.

[0081] The implementation principle of the ball valve for preventing the valve handle from getting stuck in the embodiment of the present application is as follows: the valve stem 3 is rotated by the handle 31, and the valve stem 3 drives the ball 2 to rotate. During the rotation process, the valve stem 3 drives the inner ring 141 to rotate, and the inner ring 141 drives the ball 143 to rotate. The ball 143 pushes the slide rod 41 to move along the oil filling hole 1421, and the slide rod 41 drives the sealing cover 42 to move, so as to open the oil filling hole 1421, and the lubricating oil flows to the ball 143;

[0082] At the same time, the sealing cover 42 squeezes the compression spring 43 to accumulate elastic force. When the ball 143 rotates away, the slide bar 41 is reset under the elastic force of the compression spring 43, and the sealing cover 42 blocks the oil filling hole 1421 again to effectively seal.

[0083] During the opening process of the ball valve, the connecting rod 511 drives the valve seat 512 to rotate, and the valve seat 512 drives the clamping block 515 to move; when the ball valve is opened, the clamping block 516 slides along the inclined surface of the clamping block 515 to the bottom surface of the clamping block 515, clamping the clamping block 515 to ensure that the ball 143 is misaligned with the rotating ball 32;

[0084] When the ball valve needs to be closed, the ball 32 continues to rotate, the clamping block 516 slides to the inclined surface of the sliding block 521, and then rotates in the opposite direction. Under the action of the clamping force, the clamping block 516 drives the sliding block 521 to move in the direction of the clamping block 515, the sliding block 521 abuts against the clamping block 515, and the clamping block 516 slides to the inclined surface of the clamping block 515 again, thereby sliding away from the clamping block 515, making it easy to rotate and reset the ball valve, thereby improving the rotation stability of the ball valve.
