Technical Field
[0001] This invention relates to the field of mechanical manufacturing technology, specifically to a rapid opening and closing mechanism for industrial valves in mechanical manufacturing. Background Technology
[0002] Valves, as an indispensable and crucial component of pipeline systems, play a vital role in precisely controlling the flow of fluids (including liquids such as water and oil, as well as gases such as natural gas and air) within the pipeline. The valve's opening and closing mechanism is the core device for achieving this function, driving the valve's closing element (such as gates, balls, and discs) to perform corresponding movements. When fluid flow is required in production or daily life, operators can open the valve using the opening and closing mechanism. Taking electric valves as an example, the operator simply presses a control button, starting the motor and driving the closing element through a transmission device, ensuring unobstructed flow and allowing fluid to be transported according to a preset path and flow rate. Similarly, when fluid flow needs to be stopped, the opening and closing mechanism drives the closing element to close the valve, thus cutting off the fluid passage and preventing unnecessary waste or safety hazards caused by continued fluid flow. In daily life, our common household water pipe systems perfectly exemplify this function of valves. Ball valves, as a common type of valve, primarily consist of a handle, stem, and ball in their opening and closing mechanism. The handle and valve stem are reliably connected, ensuring that the valve stem rotates synchronously when the handle is turned. The other end of the valve stem is securely connected to the ball, and the rotation of the valve stem causes the ball to rotate precisely 90° within the valve body. To open the ball valve, the operator grips the handle and turns it in a specific direction. As the handle rotates, the valve stem also rotates, causing the ball to rotate within the valve body. When the ball's through-hole aligns with the pipeline axis, the valve is open. At this time, the fluid in the pipeline can flow smoothly through the ball's through-hole without obstruction. The fluid flow is relatively stable when passing through the valve, with minimal pressure loss, ensuring efficient operation of the entire pipeline system. To close the ball valve, the operator turns the handle in the opposite direction. The valve stem rotates in the opposite direction, causing the ball to continue rotating 90°. When the ball rotates to the point where its solid part blocks the pipeline passage, the valve is closed. At this time, the solid part of the ball completely blocks the fluid passage, preventing further fluid flow and achieving the purpose of fluid shut-off. When closed, the ball valve effectively prevents fluid leakage, ensuring the sealing and safety of the pipeline system; During rapid opening and closing, the resistance of the sealing ring increases the torque of the drive rod, requiring the drive housing to provide greater driving force. This not only increases energy consumption but may also place additional load on the drive housing, shortening its service life. Secondly, excessive resistance can cause the drive rod to rotate unevenly, resulting in jamming and affecting the valve's rapid opening and closing response speed, thus reducing the overall system efficiency.
[0003] Combining the above issues, we find that existing valve quick-opening and closing mechanisms on the market cannot simultaneously avoid the problems mentioned above when in use. Even if they can be solved, they require the use of external tools, thus failing to achieve the desired effect. Therefore, we propose a quick-opening and closing mechanism for valves in the mechanical manufacturing industry. Summary of the Invention

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0019] Example 1 Please refer to the accompanying drawings. This invention provides a technical solution: a rapid opening and closing mechanism for industrial valves in mechanical manufacturing, including a drive box body 1 and a valve body 2. The main function of the drive box body 1 is to provide power for the opening and closing of the valve. The valve body 2 is correspondingly arranged at the bottom of the drive box body 1. Connectors 3 are fixedly installed on both sides of the valve body 2. A detachable connecting pipe 4 is installed at the other end of the connector 3. The connector 3 and the connecting pipe 4 are threadedly engaged. A drive rod 5 is rotatably installed at the bottom of the drive box body 1. A ball valve body 6 is fixedly installed at the bottom of the drive rod 5. It is worth noting that the ball valve body 6 belongs to the prior art. The ball valve body 6 is located inside the valve body 2. An extrusion assembly 10 is fixedly installed on the outside of the drive rod 5. The extrusion assembly 10 includes a sealing ring 101 fitted and sleeved on the outside of the drive rod 5. A separation groove 1011 is formed inside the sealing ring 101, dividing the sealing ring into two parts. An extrusion plate 102 is slidably connected inside the separation groove 1011, and the extrusion plate 102 is used to extrude the sealing ring 101. A rotating ring 103 is also fixedly sleeved on the outside of the drive rod 5. Four arc-shaped grooves 104 are formed on the surface of the rotating ring 103. The distance between the two ends of the arc-shaped grooves 104 and the inner wall of the rotating ring 103 decreases from far to near. A sliding plate 105 is slidably connected above the arc-shaped grooves 104. The sliding plate 105 and the extrusion plate 102... A connecting rod 106 is fixedly connected to the valve body 2. An extension plate 107 is fixedly connected to the side of the sliding plate 105. A fixing ring 108 is fixedly connected to the top of the valve body 2. A connecting column 109 is fixedly connected between the extension plate 107 and the fixing ring 108. Since the distance between the two ends of the arc groove 104 and the inner wall of the rotating ring 103 decreases from far to near, the extension plate 107 sliding on the arc groove 104 can drive the connecting rod 106 to squeeze the separation groove 1011, reducing the contact gap between the driving rod 5 and the outer ring of the sealing ring 101, thereby reducing the normal pressure between the driving rod 5 and the inner ring of the sealing ring 101, and thus reducing the friction.
[0020] As a further definition of the extrusion assembly 10 of the present invention, the sealing ring 101 is located between the fixed ring 108 and the drive rod 5. The sealing ring 101 includes an outer ring and an inner ring, which are located on both sides of the extrusion plate 102. The extrusion plate 102 is used to extrude the inner wall of the outer ring. As the connecting rod 106 drives, the extrusion plate 102 moves toward the outer ring of the sealing ring 101. When the extrusion plate 102 moves to contact the outer ring of the sealing ring 101, it applies a moderate extrusion force. By extruding the outer ring of the sealing ring 101 with the extrusion plate 102, the contact state between the two can be optimized, the contact pressure can be reduced, and thus the friction can be reduced. There are four extrusion plates 102, and each extrusion plate 102 is set as an arc-shaped titanium alloy plate. There are four sets of connecting rods 106, and each set contains three connecting rods 106.
[0021] It should be noted that the compression of the outer ring of the sealing ring 101 by the extrusion plate 102 allows the drive rod 5 to rotate relatively easily when the inner ring of the sealing ring 101 rotates, reducing the resistance between the drive rod 5 and the sealing ring 101. However, there is no gap between the drive rod 5 and the sealing ring 101, so it will not fail to seal.
[0022] The specific implementation of this embodiment is as follows: To optimize the performance of the drive rod 5 during rotation and reduce the resistance between it and the sealing ring 101, a compression assembly 10 is specially provided. The drive box body 1 serves as a power source, and its internal drive mechanism can generate driving force. The drive box body 1 starts and drives the drive rod 5 to rotate. A rotating ring 103 is installed on the outside of the drive rod 5. When the drive rod 5 rotates, the rotating ring 103 rotates synchronously. The rotation of the rotating ring 103 will further drive the sliding plate 105 connected to it to move. The sliding plate 105 slides along the arc groove 104. At the bottom of the sliding plate 105, a connecting rod 106 is firmly connected. The connecting rod 106 plays a role in force transmission, converting the movement of the sliding plate 105 into the movement of the compression piece 102. With the drive of the connecting rod 106, the compression piece 102 moves towards the outer ring of the sealing ring 101. When the compression piece 102 moves to contact the outer ring of the sealing ring 101, it will apply a moderate compression force to it. By squeezing the outer ring of the sealing ring 101 with the extrusion plate 102, the contact state between the two can be optimized, the contact pressure can be reduced, and thus the friction can be reduced.
[0023] Throughout the process, as the drive rod 5 rotates, the resistance between it and the sealing ring 101 is significantly reduced due to the optimized effect of the extrusion assembly 10 on the sealing ring 101. This not only improves the smoothness of the drive rod 5's rotation and reduces energy loss, but also extends the service life of the drive rod 5 and the sealing ring 101. Furthermore, it ensures the stable operation of the entire device and reduces the failures and maintenance costs that may be caused by excessive resistance.
[0024] Example 2 Please refer to the accompanying drawings. This invention provides a technical solution: a rapid opening and closing mechanism for valves in the machinery manufacturing industry. This invention addresses the technical problems mentioned in the background art with corresponding improvements.
[0025] As a further definition of the locking component 20 of the present invention, the locking component 20 is provided inside the valve body 2. The locking component 20 includes an abutment plate 201 fixedly sleeved on the outside of the drive rod 5. A fixing block 202 is fixedly connected inside the valve body 2. An arc-shaped abutment block 203 is fixedly connected to the side of the fixing block 202. The abutment plate 201 and the arc-shaped abutment block 203 intermittently abut against each other.
[0026] The fixed block 202 has a cavity 204 inside. The side of the arc-shaped contact block 203 is fixedly connected to a first wedge block 205. The bottom of the first wedge block 205 is fixedly connected to a guide block 2051. The guide block 2051 is slidably connected to the inner wall of the cavity 204. The inner wall of the valve body 2 has an installation cavity 206. The second wedge block 207 is slidably connected inside the installation cavity 206. A return spring 208 is fixedly connected between the second wedge block 207 and the inner wall of the installation cavity 206. The first wedge block 205 and the second wedge block 207 are fitted together, and the end of the second wedge block 207 is pressed against the end of the first wedge block 205. The inner wall of the connecting pipe 4 has a locking groove 209. The other end of the second wedge block 207 is intermittently engaged with the locking groove 209. The contact plate 201 is set as a gourd plate, and the surface of the contact plate 201 slides against the surface of the arc-shaped contact block 203.
[0027] The specific implementation method of this embodiment is as follows: To enhance the stability and reliability of the pipe connection structure, a locking component 20 is provided. At the start of operation, the operator needs to connect the connecting pipe 4 to the connector 3. The end of the connecting pipe 4 is designed with precise external threads, while the connector 3 has matching internal threads machined inside. The operator needs to slowly screw the connecting pipe 4 into the connector 3 with appropriate force to ensure full engagement between the threads, thus forming a preliminary connection between the connecting pipe 4 and the connector 3.
[0028] When the device is started, the drive rod 5 begins to rotate. The rotation of the drive rod 5 is driven by power provided by the drive unit. A contact plate 201 is securely mounted on the drive rod 5, and the contact plate 201 rotates synchronously with the drive rod 5. As the drive rod 5 rotates, the contact plate 201 also begins to move in a circular motion around the axis of the drive rod 5. Two arc-shaped blocks are distributed on the outer side of the circumference of the contact plate 201. When the contact plate 201 rotates, its edge gradually contacts the arc-shaped contact blocks 203, applying an outward squeezing force. This squeezing force causes the arc-shaped contact blocks 203 to move. A first wedge block 205 is provided on the side of the arc-shaped contact block 203. The inclined surface of the first wedge block 205 fits against the outer surface of the arc-shaped contact block 203. When the arc-shaped contact block 203 moves outward, it applies a horizontal thrust to the first wedge block 205. Under the action of this thrust, the first wedge block 205 will move toward the second wedge block 207.
[0029] The second wedge block 207 and the first wedge block 205 cooperate with each other, and their ends are designed with wedge-shaped inclined surfaces at a specific angle. When the first wedge block 205 moves toward the second wedge block 207, the inclined surfaces of the two wedge blocks will contact and press against each other. This pressing engagement causes the second wedge block 207 to move toward the engagement groove 209.
[0030] The locking groove 209 is a pre-cut groove on the side of the connecting pipe 4. When the second wedge block 207 moves under the squeezing action of the first wedge block 205, its bottom gradually inserts into the locking groove 209. As the second wedge block 207 continues to move, a tight locking connection is formed between it and the locking groove 209. When the abutment plate 201 no longer abuts, the return spring 208 drives the second wedge block 207 to return to its original position. This locking connection effectively prevents relative rotation or loosening between the connecting pipe 4 and the connector 3 when fluid passes through, thereby ensuring the stability of the entire connection structure. Through the above series of mechanical actions, the locking assembly 20 automatically completes the locking operation between the connecting pipe 4 and the connector 3 during the rotation of the drive rod 5, providing a reliable guarantee for the stable operation of the pipeline system.
[0031] It should be noted that the specific models, working principles and usage of the drive box body 1, valve body body 2 and ball valve body 6 are well known to those skilled in the art, and will not be elaborated upon here.
