Description

Technical Field

[0001] This utility model belongs to the field of valve manufacturing technology, and specifically refers to a mixed-adsorption cooling device for valve balls. Background Technology

[0002] As a core component of valves, the valve ball is widely used in numerous industrial fields such as petroleum, chemical, power, and metallurgy. Its main function is to control the flow rate and direction of fluids within pipelines through rotation, playing a crucial role in ensuring the safe and stable operation of pipeline systems. Because the valve ball frequently comes into contact with the fluid medium during operation and is often subjected to the scouring of high pressure, high temperature, and high-speed fluids, extremely high requirements are placed on its wear resistance.

[0003] Despite various measures taken to improve the wear resistance of valve balls in existing manufacturing and application technologies, such as selecting wear-resistant materials and performing surface hardening treatments, many problems still exist. For example, under harsh operating conditions involving high temperature, high pressure, and solid particles, the ball surface is prone to wear, scratches, and even peeling. This wear not only leads to a decrease in the valve's sealing performance, causing fluid leakage and affecting production efficiency, but may also increase maintenance costs and downtime due to frequent replacement of valve balls. Therefore, there is still significant room for improvement in the wear resistance of valve balls in existing technologies, and an innovative technical solution is urgently needed to effectively address this issue.

[0040] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. See also: Figure 1-5 :

[0041] Example 1:

[0042] This embodiment provides a device for cooling and discharging a valve ball, including a hoist 1, and further comprising:

[0043] The circulating mixing mechanism 2 includes a mixing box 20 located below the starting point of the elevator 1, a mixing feed hopper 21 located on the mixing box 20, atomizing nozzles 22 evenly arranged on both sides of the elevator 1 along the lifting direction, a recovery component 23 for sending the mist water after the atomizing nozzles 22 have worked to the mixing box 20, and a dual-shaft counter-rotating stirring component 24 for uniformly mixing water and mixing medium. The mixing box 20 supplies water to the atomizing nozzles 22.

[0044] The cooling mechanism 3 includes a cooling water tank 30 located below the end point of the elevator 1, a stirring rod 31 located longitudinally at the bottom of the cooling water tank 30, a cooling stirring paddle 32 located on the stirring rod 31, and a first motor 33 for driving the stirring rod 31 to rotate.

[0045] The mixing tank 20 serves as a container for mixing water and the mixing medium, and also supplies water to the atomizing nozzle 22, ensuring sufficient mixed solution for subsequent mixing treatment of the valve ball. The mixing tank 20 is generally a rectangular or cylindrical box structure for easy installation and placement. Located below the starting point of the elevator 1, the mixing tank 20 facilitates the receipt of mist water recovered from the recovery component 23, and also provides water supply to the atomizing nozzles 22 located on both sides of the elevator 1. The mixing tank 20 can be connected to the atomizing nozzles 22 via pipes to achieve water supply.

[0046] The mixing feed hopper 21 is used to add mixing media into the mixing tank 20, facilitating control of the amount and speed of media addition. The mixing feed hopper 21 is generally funnel-shaped with a large opening for easy media addition. Its bottom is connected to the mixing tank 20. The shape of the mixing feed hopper 21 is typically conical or square-pyramidal to facilitate media flow. The mixing feed hopper 21 can be welded or sealed to the side of the mixing tank 20 for convenient media addition by operators.

[0047] The atomizing nozzle 22 is used to atomize the mixture in the mixing tank 20 and spray it onto the valve ball, allowing the mixed medium to adhere to the surface of the ball, achieving contact and adhesion between the mixed medium and the valve ball, and improving the wear resistance of the ball. The atomizing nozzles 22 are evenly distributed on both sides of the elevator 1 along the lifting direction, which can fully cover the valve ball during the lifting process. The atomizing nozzles 22 can be connected to the mixing tank 20 through pipes to receive the mixed medium; they can be fixed on both sides of the elevator 1 by bolt connection or clamp connection, etc.

[0048] The recycling component 23 collects the mist water after the atomizing nozzle 22 has worked and sends it back to the mixing tank 20, realizing the recycling of resources, saving water resources and mixing media, reducing costs, and reducing the impact on the environment.

[0049] The dual-shaft counter-rotating agitator 24 ensures uniform mixing of water and adsorption medium within the adsorption tank 20, guaranteeing the quality of the mixture, improving the dispersion of the adsorption medium in the water, and making the mixture more uniform, thereby enhancing the adsorption effect on the valve ball.

[0050] The cooling water tank 30 serves as a container for holding the valve ball and providing it with a cooling environment. It typically contains water or other specific cooling liquids to absorb heat from the valve ball. The cooling water tank 30 is generally a rectangular or cylindrical box structure. This shape maximizes volume within a limited space and facilitates manufacturing and installation. The cooling water tank 30 is positioned below the end point of the elevator 1, allowing the valve ball transported from the elevator 1 to fall directly into it for cooling, ensuring process continuity. The cooling water tank 30 can be placed on the ground using a bracket, base, or in direct contact with the ground.

[0051] The stirring rod 31 serves as a transmission component, transmitting the rotational power of the motor to the cooling stirring paddle 32. Simultaneously, it drives the cooling stirring paddle 32 to rotate within the cooling water tank 30, thereby agitating the coolant and pushing the valve ball. The stirring rod 31 is typically a slender rod-shaped structure, with one end located at the bottom of the cooling water tank 30 and connected to the output shaft of the first motor 33 via a coupling. The other end extends into the cooling water tank 30, and cooling stirring paddles 32 are installed at different positions on the rod.

[0052] The cooling agitator 32 is used to improve the cooling effect and uniformity of the valve ball, ensuring the quality of the ball during the cooling process.

[0053] Example 2:

[0054] This embodiment provides a mixing and cooling device for a valve ball, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0055] The recycling component 23 includes:

[0056] A recycling trough plate 230 is located below the elevator 1, and the extension direction of the recycling trough plate 230 is consistent with the lifting angle;

[0057] The recovery pipe 231 is connected at one end to the lowest end of the recovery tank plate 230 and at the other end to the mixing tank 20.

[0058] The recovery trough 230 is used to collect the mist that falls from the atomizing nozzle 22 after operation and guides the mist to flow towards the recovery pipe 231. The recovery trough 230 is typically a plate-like structure with a certain angle of inclination, generally elongated in shape, located below the elevator 1, and extending in the same direction as the lifting angle. This maximizes the collection of mist falling from the elevator 1. The recovery trough 230 can be fixed to the support below the elevator 1 by bolts or welding to ensure its stable position.

[0059] The recovery pipe 231 transports the mist collected by the recovery trough plate 230 to the mixing tank 20, realizing the recycling of the mist. The recovery pipe 231 is generally a tubular structure, with one end connected to the lowest end of the recovery trough plate 230 and the other end connected to the mixing tank 20, so that the mist can flow naturally into the mixing tank 20 by gravity. The recovery pipe 231 is connected to the recovery trough plate 230 and the mixing tank 20 through a sealing joint to prevent mist leakage.

[0060] In this embodiment, after the atomizing nozzle 22 is in operation, the mist will fall through the gap between the valve ball and the elevator 1 onto the recovery trough 230. Since the recovery trough 230 has a certain inclination, the mist flows down the recovery trough 230 to the lowest end under the action of gravity, and then flows into the mixing tank 20 through the recovery pipe 231, realizing the recovery and recycling of the mist.

[0061] Example 3:

[0062] This embodiment provides a mixing and cooling device for a valve ball, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0063] The dual-axis counter-rotating stirring assembly 24 includes:

[0064] Two stirring shafts 240 are arranged parallel to each other in the longitudinal direction inside the mixing tank 20;

[0065] The stirring blades 241 are evenly arranged longitudinally on two stirring shafts 240, and the stirring blades 241 on the two stirring shafts 240 are staggered.

[0066] Two second motors 242 are used to drive two stirring shafts 240 to rotate in opposite directions.

[0067] The stirring shaft 240 serves as the power transmission and support component for the stirring blades 241. It transmits the rotational power of the second motor 242 to the stirring blades 241, causing them to rotate within the mixing chamber 20, thereby achieving the mixing of water and the adsorbed medium. The stirring shaft 240 is typically a slender shaft structure, arranged longitudinally parallel to each other within the mixing chamber 20. It is generally located near the center of the mixing chamber 20 and extends through the upper and lower parts of the mixing chamber 20, allowing the stirring blades 241 to cover a large area within the mixing chamber 20. One end of the stirring shaft 240 can be located at the bottom of the mixing chamber 20, and this end can be tightly connected to the output shaft of the second motor 242 via a coupling.

[0068] The stirring blades 241 rotate under the drive of the stirring shafts 240, stirring the water and mixing medium in the mixing tank 20 to ensure thorough mixing and improve the uniformity of the mixture. The stirring blades 241 are generally blade-shaped, and their common shapes include propeller-shaped, paddle-shaped, and anchor-type. The stirring blades 241 are evenly distributed longitudinally on the two stirring shafts 240, covering most of the length of the stirring shafts 240, to ensure that the mixture in all locations within the mixing tank 20 is thoroughly stirred when the stirring shafts 240 rotate. The stirring blades 241 can be connected to the stirring shafts 240 by welding or bolts.

[0069] Example 4:

[0070] This embodiment provides a mixing and cooling device for a valve ball, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0071] The mixing medium entering the mixing box 20 from the mixing feed hopper 21 is nano-ceramic particles.

[0072] Nano-ceramic particles, as a mixing medium, can form a wear-resistant protective layer on the surface of the valve ball due to their high hardness and good wear resistance, significantly improving the ball's wear resistance. At the same time, their excellent high temperature resistance and chemical stability can ensure stable performance under complex working conditions and during the mixing process. Their good dispersibility also ensures uniform adhesion to the ball, enhancing the wear resistance effect in all aspects.

[0073] Example 5:

[0074] This embodiment provides a mixing and cooling device for a valve ball, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0075] The cooling stirring paddle 32 includes:

[0076] Heat dissipation blades 320 are evenly arranged longitudinally on stirring rod 31, and heat dissipation fins 321 are attached to the heat dissipation blades 320;

[0077] The pusher blade 322 is located near the bottom of the cooling water tank 30 on the stirring rod 31. The pusher blade 322 is used to push the ball to roll inside the cooling water tank 30.

[0078] The cooling blades 320 are used to accelerate the flow of coolant in the cooling tank 30. By increasing the contact area and flow velocity between the coolant and the valve ball, the heat exchange efficiency between them is enhanced, quickly transferring the heat emitted by the valve ball to the coolant. The heat is then dissipated by the blades themselves and the heat sink 321, thus cooling the valve ball. The cooling blades 320 consist of a blade body and heat sinks 321 attached to it. The blade body is typically a rectangular, trapezoidal, or arc-shaped flat plate structure to allow for smooth rotation in the coolant. The heat sinks 321 are generally thin sheets tightly attached to the surface of the blade body, increasing the heat dissipation area to improve the heat dissipation effect. The cooling blades 320 are evenly distributed longitudinally on the stirring rod 31, located near the middle and upper part of the tank. This position allows the blades to effectively agitate most of the coolant in the tank during rotation, ensuring good convection circulation throughout the tank, fully covering the area around the valve ball, and improving heat exchange efficiency. The heat dissipation blade 320 is firmly fixed to the stirring rod 31 by welding, bolting, or riveting to ensure that the blade will not fall off when the stirring rod 31 rotates at high speed. The heat sink 321 is usually bonded or welded to the blade body with thermally conductive adhesive to ensure good heat conduction, so that heat can be smoothly transferred from the blade body to the heat sink 321 and dissipated.

[0079] When the stirring rod 31 rotates, the pusher blade 322 contacts the surface of the valve ball and applies a thrust, pushing the ball to roll at the bottom of the cooling water tank 30. By changing the position and orientation of the ball, all parts of the ball can be evenly contacted with the coolant, thereby achieving uniform cooling. The pusher blade 322 is shaped like a shovel or a blade with a certain degree of curvature and is located near the bottom of the cooling water tank 30 on the stirring rod 31. In this way, when the stirring rod 31 rotates, the pusher blade 322 can directly act on the valve ball, using the rotational force of the stirring rod 31 to push the ball to roll at the bottom of the water tank. The pusher blade 322 can be fixed to the stirring rod 31 by welding, bolting, or other suitable methods.

[0080] In this embodiment, after the valve ball enters the cooling water tank 30, the first motor 33 drives the stirring rod 31 to rotate, which in turn drives the cooling blades 320 and the pusher blades 322 to rotate synchronously. During rotation, the cooling blades 320 push the coolant to form convection within the cooling water tank 30, increasing the contact area and flow rate between the coolant and the valve ball, enhancing heat exchange efficiency, and transferring heat from the ball to the coolant. Simultaneously, the heat dissipation fins 321 on the cooling blades 320 utilize their large heat dissipation area to dissipate heat from the coolant into the surrounding environment. As the stirring rod 31 rotates, the pusher blades 322 contact the surface of the valve ball and apply thrust, causing the ball to roll at the bottom of the tank, changing the contact position between the ball and the coolant, ensuring that all parts of the ball can uniformly exchange heat with the coolant, achieving a comprehensive and uniform cooling effect.

[0081] Example 6:

[0082] This embodiment provides a mixing and cooling device for a valve ball, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0083] The elevator 1 is provided with a plurality of placement slots 4 for placing spheres, and the placement slots 4 are hemispherical groove structures adapted to the spheres.

[0084] The elevator 1 is equipped with a hemispherical groove 4 that fits the sphere, providing stable support for the sphere. During the operation of the elevator 1, this effectively prevents the sphere from shaking, shifting, or even falling, ensuring the safety of sphere transportation and avoiding interference with subsequent mixing and cooling processes due to sphere instability. Secondly, this design allows the sphere to maintain a specific posture in the groove 4, which facilitates the precise and uniform spraying of the mixing liquid onto the sphere surface by the atomizing nozzle 22, improving the mixing effect.

[0085] Example 7:

[0086] This embodiment provides a mixing and cooling device for a valve ball, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0087] The hoist 1 is equipped with a splash guard 5, the splash guard 5 comprising:

[0088] A rotating base 50 is located on one side of the hoist 1;

[0089] The cover 51 covers the placement groove 4. The fixed end of the cover 51 can rotate around the rotating base 50, and the movable end can be connected to the other side of the elevator 1 after rotation.

[0090] The rotating base 50 provides a rotational support point for the cover 51, allowing the cover 51 to rotate around it and thus open and close, thereby controlling the coverage state of the splash guard 5 over the placement slot 4. The rotating base 50 typically consists of a fixed base and a rotating shaft. The fixed base is used to mount the rotating base 50 onto the hoist 1, while the rotating shaft is connected to the cover 51, allowing the cover 51 to rotate around the shaft. The rotating base 50 is generally located on the side of the hoist 1 near the top or middle to ensure that the cover 51 completely covers the placement slot 4 when rotating. The fixed base can be securely fixed to the hoist 1 by bolts or welding to ensure it does not loosen during equipment operation. The rotating shaft and the fixed base can be connected by bearings to allow for flexible rotation.

[0091] When the equipment is running, the cover 51 covers the placement tank 4, preventing the mist generated by the atomizing nozzle 22 from splashing into the surrounding environment and keeping the working area clean. It also helps prevent external impurities from entering the placement tank 4 and affecting the adsorption effect of the valve ball. The cover 51 is generally an arc-shaped structure located above the placement tank 4 on the elevator 1. Its fixed end is connected to the rotating base 50 and can rotate around the rotating base 50. The movable end, after rotation, can connect to the other side of the elevator 1, achieving complete coverage of the placement tank 4. The fixed end is connected to the rotating base 50 via a rotating shaft to achieve rotation; the movable end can be connected to the other side of the elevator 1 via a magnetic connector 6 or other connecting device, maintaining the stability of the cover 51 when closed.

[0092] Example 8:

[0093] This embodiment provides a mixing and cooling device for a valve ball, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0094] A magnetic connection assembly 6 is provided between the cover 51 and the hoist 1, the magnetic connection assembly 6 comprising:

[0095] The first magnetic contact piece 60 is evenly arranged on the movable end of the cover 51;

[0096] The second magnetic connector 61 is arranged on the hoist 1 corresponding to the first magnetic connector 60, and the second magnetic connector 61 and the first magnetic connector 60 attract each other.

[0097] The operating handles 62 are evenly distributed on the movable end of the cover 51.

[0098] The magnetic connector 6 is used to tightly connect the movable end of the cover 51 to the hoist 1 using magnetic force when the cover 51 is closed, ensuring that the cover 51 will not open due to vibration or other external forces during equipment operation, thus guaranteeing the splash-proof effect. Simultaneously, when it is necessary to open the cover 51, the magnetic force can be easily overcome to open the cover 51. The magnetic connector 6 consists of a first magnetic connector 60 and a second magnetic connector 61. The first and second magnetic connectors 60 and 61 are typically magnetic sheet-like structures, generally rectangular or circular in shape, and small in size, facilitating their even distribution at the connection between the cover 51 and the hoist 1. The first magnetic connector 60 is located at the edge of the movable end of the cover 51, evenly distributed along the edge; the second magnetic connector 61 is located on the hoist 1 at a corresponding position to the first magnetic connector 60. When the cover 51 is closed, the two can accurately align and attract each other. The first magnetic connector 60 can be fixed to the movable end of the cover 51 by means of adhesive, welding, or riveting; the second magnetic connector 61 is fixed to the hoist 1 in a similar manner. The magnetic connectors attract each other through magnetic force, thus connecting the cover 51 to the hoist 1.

[0099] The operating handle 62 provides an operating point for the operator, facilitating the opening and closing of the cover 51 and improving operational convenience. The operating handle 62 is typically a plate-like structure with a gripping portion for the operator to hold. The operating handles 62 are evenly distributed at the movable end of the cover 51, generally located at the edge of the movable end, allowing the operator to easily grasp the handles for operation while standing or near the hoist 1. The operating handles 62 can be connected to the movable end of the cover 51 by welding, bolting, or snap-fit ​​connections, ensuring that the operating handles 62 will not loosen or fall off during use.

[0100] In this embodiment, the splash guard 5 operates based on the principles of mechanical rotation and magnetic connection. Before the equipment is put into operation, the operator rotates the guard 51 around the rotating base 50 to cover the placement slot 4 using the operating handle 62. At this time, the first magnetic contact 60 at the movable end of the guard 51 attracts the second magnetic contact 61 on the lifting machine 1, firmly connecting the guard 51 to the lifting machine 1. When the atomizing nozzle 22 is working, the guard 51 prevents the mist from splashing into the surrounding environment. When it is necessary to place or remove the valve ball, the operator holds the operating handle 62 again, overcomes the magnetic force between the magnetic contacts, and rotates the guard 51 around the rotating base 50 to open it, exposing the placement slot 4.

[0101] Example 9:

[0102] This embodiment provides a mixing and cooling device for a valve ball, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0103] A guide buffer frame 7 is also provided below the end position of the elevator 1, and the guide buffer frame 7 includes:

[0104] The guide frame 70 is connected to the bottom end position of the elevator 1, and the guide frame 70 is inclined along the direction of the cooling water tank 30.

[0105] A buffer pad 71 is provided on the guide frame 70, and the buffer pad 71 is in direct contact with the ball.

[0106] The guide frame 70 guides the valve ball falling from the end position of the elevator 1, ensuring it enters the cooling water tank 30 accurately along a predetermined path. This prevents the ball from falling off-center, which could lead to ineffective cooling or damage to the cooling water tank 30 and its internal components. The guide frame 70 is typically a plate-like structure with an inclined angle designed to allow the ball to fall smoothly into the cooling water tank 30. The guide frame 70 is connected to the bottom of the elevator 1 at the corresponding end position, with one end connected to the elevator 1 and the other end extending above the cooling water tank 30. The guide frame 70 and the elevator 1 can be securely connected by welding, bolting, or flange connections.

[0107] As the valve ball slides down the guide frame 70 into the cooling water tank 30, the buffer pad 71 directly contacts the ball, buffering the impact force generated when the ball falls, reducing damage to the ball due to collision, and also reducing the impact on the guide frame 70 and the cooling water tank 30, protecting equipment components. The buffer pad 71 is generally a sheet or block structure, and its shape can be an arc adapted to the contact area of ​​the ball surface. The buffer pad 71 is set on the guide frame 70, located at the position where it directly contacts the ball on the ball's sliding path. The buffer pad 71 can be fixed to the guide frame 70 by means of adhesive, bolt connection, or snap-on connection.

[0108] In this embodiment, after the valve ball reaches the destination position from the elevator 1, the guide frame 70, connected to the elevator 1 and inclined, allows the ball to slide down the guide channel of the guide frame 70 towards the cooling water tank 30 under the action of gravity. During the descent, the ball comes into direct contact with the buffer pad 71 on the guide frame 70. The buffer pad 71 absorbs the impact force generated by the ball's fall using its own elastic deformation, converting the impact force into the elastic potential energy of the buffer pad 71, thereby reducing the impact force on the ball and protecting it from damage. At the same time, the buffering effect of the buffer pad 71 also reduces the impact of the ball on the guide frame 70 and the cooling water tank 30, ensuring the normal operation of the equipment. The structural shape and inclination angle of the guide frame 70 ensure that the ball can accurately enter the cooling water tank 30 along the predetermined path, completing the transfer process.

[0109] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Therefore, all equivalent changes made to the structure, shape, and principle of the present utility model should be covered within the scope of protection of the present utility model.
