[0002] In modern industrial production, processes are becoming increasingly complex, and operating conditions are constantly changing. Fluid parameters such as temperature, pressure, and flow rate change continuously with production stages and chemical reactions. The development of flexible control valves aims to meet the need for flexible and precise fluid regulation under various operating conditions, such as high temperature, high pressure, and highly corrosive environments. In experimental industrial production plants or research facilities, processes may frequently change, requiring continuous adjustments to fluid control strategies. This may necessitate replacing different control valves for different operating environments. Therefore, we propose a flexible switching control valve. Summary of the Invention

Each disassembly device includes two fixing frames, which are respectively fixedly connected to both sides of the control valve body. A shaped frame is slidably connected to the inner surface of the fixing frames. A square plate is slidably connected to the surface of the control valve body. Two connecting plates are fixedly connected to the surface of the square plate. The connecting plates are slidably connected to the surface of the shaped frame. A sliding rod is slidably inserted into the shaped frame. A circular plate is fixedly connected to one end of the sliding rod, and a double-sided plate is rotatably connected to the end of the sliding rod away from the circular plate. The arc surface of the sliding rod is slidably connected to the connecting plate. Two grooves are formed on one side of the connecting plate, and two sliding holes are formed on one side of the connecting plate.

[0005] The above-mentioned components achieve the following effect: by setting up a disassembly device, it is possible to facilitate the disassembly of the control valve body by the staff, thereby avoiding problems that may occur during the use of the control valve body. Since the connection of the control valve body is relatively complex, it is necessary for the staff to use different tools, which increases the staff's working time and labor costs. This improves the practicality of the device.

[0006] Preferably, the arc surface of the slide rod is fitted with a first spring, and the two ends of the first spring are fixedly connected to the irregular frame and the circular plate, respectively.

[0007] The aforementioned components achieve the following effect: they improve the stability of the slide bar, preventing the control valve body from being shaken by external forces when the operator is using the control valve body, which would cause the slide bar to slide within the connecting plate and the double side plates to rotate, resulting in the control valve body shaking.

[0008] Preferably, a fixing rod is fixedly connected to the surface of the irregular frame, a single-hole plate is slidably connected to the arc surface of the fixing rod, an insert rod is fixedly connected to the surface of the single-hole plate, and a plurality of circular grooves are formed on the surface of the fixing frame, with the insert rod slidably connected to the surface of the circular grooves of the fixing frame.

[0009] The aforementioned components achieve the following effect: they adjust the height of the control valve body, preventing the control valve body from being installed too low, which would require operators to bend over or squat for extended periods to operate, increasing operator fatigue and potentially affecting operational accuracy.

[0010] Preferably, one end of the fixing rod is fixedly connected to a limiting plate, and the size of the insertion rod is adapted to the circular groove of the fixing frame.

[0011] The aforementioned components achieve the following effect: preventing the single-hole plate from being pulled off, thus avoiding situations where workers exert excessive force when adjusting the installation height of the control valve body, causing the single-hole plate to slip off the arc surface of the fixing rod and requiring secondary installation.

[0012] Preferably, the upper surface of the control valve body is provided with a dustproof device, the dustproof device including an opening frame, the opening frame being fixedly connected to the upper surface of the control valve body, a rotating rod being fixedly connected to the inner surface of the opening frame, a cover plate being rotatably connected to the arc surface of the rotating rod, a positioning plate being fixedly connected to the upper surface of the cover plate, a fixing block being fixedly connected to the surface of the opening frame, a round rod being rotatably connected to the surface of the fixing block, an operating plate being fixedly connected to one end of the round rod, the operating plate being slidably connected to the surface of the cover plate, and the operating plate being slidably connected to the positioning plate.

[0013] The above-mentioned components achieve the following effect: by setting up a dustproof device, dust is prevented from falling into the connection port, avoiding the accumulation of dust inside the connection port when the control valve body is not used for a long time, which could lead to poor contact when the connection port is needed by the operator, thus improving the practicality of the device.

[0014] Preferably, the arc surface of the rotating rod is fitted with two torsion springs, and the two ends of the torsion springs are fixedly connected to the opening frame and the cover plate, respectively.

[0015] The above-mentioned components achieve the following effect: the cover opens automatically while keeping it open, reducing the number of steps required by staff and improving their work efficiency.

[0016] Preferably, a single-sided plate is fixedly connected to the surface of the cover plate, and the size of the cover plate is adapted to the size of the connection port.

[0017] The aforementioned components achieve the following effects: they keep the cover plate in a vertical position and maintain a certain distance between the cover plate and the control valve body, making it convenient for operators to rotate the cover plate after using the connection port, thus improving the ease of use of the device.

[0018] Preferably, the surface of the rotary controller is provided with an auxiliary device, which includes three operating levers. All three operating levers are fixedly connected to the surface of the rotary controller. An arc plate is slidably connected to the arc surface of each operating lever. A protective cover is fixedly connected to the surface of each of the three arc plates. A second spring is sleeved on the arc surface of each operating lever. The two ends of the second spring are fixedly connected to the rotary controller and the arc plate, respectively.

[0019] The aforementioned components achieve the following effect: by setting up auxiliary devices, the accidental activation of the knob is reduced, preventing operators from accidentally rotating the knob when using the rotary controller, which could alter the parameters of the control valve body and cause potential malfunctions, thus improving the safety of the device.

[0020] Preferably, the surface of the rotary controller is fixedly connected to three long rods, the surface of the long rods is provided with long grooves, the surface of the long rods and long grooves is rotatably connected to a double arc plate, and the surface of the arc plate is fixedly connected to an L-shaped plate.

[0021] The aforementioned components achieve the following effect: they fix the position of the protective cover, making it convenient for staff to adjust the parameters of the knob.

[0022] Preferably, a protective pad is fixedly connected to the inner surface of the operating lever, and the protective pad is slidably connected to the surface of the arc-shaped plate.

[0023] The aforementioned components achieve the following effects: they reduce the impact between the curved plate and the operating lever, extend the service life of the operating lever, and improve the reliability of the device.

[0024] Compared with the prior art, the beneficial effects of the present invention are: 1. By incorporating a disassembly device, this invention facilitates the disassembly of the control valve body by operators, preventing problems that may arise during its use. The complex connections of the control valve body necessitate the use of various tools, increasing working hours and labor costs. This invention enhances the practicality of the device.

[0025] 2. By incorporating a dustproof device, this invention prevents dust from falling into the connection port, thus avoiding dust accumulation inside the connection port when the control valve body is not used for a long time. This prevents poor contact at the connection port when the operator needs to use it, thereby improving the practicality of the device.

[0026] 3. By incorporating an auxiliary device, this invention reduces the risk of accidental knob activation, preventing accidental rotation of the control valve body due to accidental knob activation while using the rotary controller. This avoids potential malfunctions caused by changes in the valve body's parameters, thus enhancing the device's safety. Attached Figure Description

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0030] Please see Figure 1 This invention provides a technical solution: a flexible switching control valve, including a control valve body 1, two metering chambers 2 mounted on the surface of the control valve body 1, two rotary controllers 3 mounted on the surface of the control valve body 1, two knobs 7 mounted on the surface of the rotary controllers 3, a connection port 8 mounted on the upper surface of the control valve body 1, and disassembly devices 4 provided on both sides of the control valve body 1. By providing disassembly devices 4, the invention facilitates the disassembly of the control valve body 1 by operators, preventing problems during use. The complex connection of the control valve body 1 necessitates the use of different tools, increasing working time and labor costs. This invention improves efficiency. To enhance the practicality of the device, a dustproof device 5 is provided on the upper surface of the control valve body 1. This prevents dust from falling into the connection port 8, thus avoiding dust accumulation inside the connection port 8 when the control valve body 1 is not used for a long time. This prevents poor contact at the connection port 8 when the operator needs to use it, thereby improving the device's practicality. An auxiliary device 6 is provided on the surface of the rotary controller 3. This reduces the chance of accidental activation of the knob 7, preventing accidental rotation of the knob 7 when the operator is using the rotary controller 3. This would change the parameters of the control valve body 1 and potentially cause malfunctions, thus improving the device's safety.

[0031] The following section will explain the specific setup and function of its disassembly device 4, dustproof device 5, and auxiliary device 6.

[0032] like Figure 2 and Figure 3 and Figure 4 as well as Figure 5As shown, the two disassembly devices 4 include two fixing frames 401, which are fixedly connected to both sides of the control valve body 1 respectively. A shaped frame 404 is slidably connected to the inner surface of the fixing frame 401. A square plate 402 is slidably connected to the surface of the control valve body 1. Two connecting plates 403 are fixedly connected to the surface of the square plate 402. The connecting plates 403 are slidably connected to the surface of the shaped frame 404. A sliding rod 405 is slidably inserted into the shaped frame 404. A circular plate 406 is fixedly connected to one end of the sliding rod 405, and a double-sided plate 407 is rotatably connected to the end of the sliding rod 405 away from the circular plate 406. The arc surface of the sliding rod 405 is slidably connected to the connecting plate 403. Two grooves 413 are formed on one side of the connecting plate 403. Two sliding holes 414 are provided. A first spring 412 is fitted onto the arc surface of the sliding rod 405. The two ends of the first spring 412 are fixedly connected to the irregular frame 404 and the circular plate 406, respectively. When the operator needs to install the control valve body 1, the operator can first move the control valve body 1 to slide on the surface of the connecting plate 403 until the surface of the control valve body 1 is in contact with the square plate 402. At this time, the operator can push the circular plate 406 to drive the sliding rod 405 to slide inside the irregular frame 404. At this time, the first spring 412 is stretched, and the sliding rod 405 drives the double-sided plate 407 to slide on the surface of the sliding hole 414 of the connecting plate 403 until the double-sided plate 407 is completely separated from the connecting plate 403. Then the operator can rotate the double-sided plate 407. When the double-sided plate 407 rotates... After moving to a certain angle, the operator can release the circular plate 406. At this time, the rebound force of the first spring 412 drives the circular plate 406 to move. The circular plate 406 drives the slide rod 405 to slide inside the irregular frame 404. The slide rod 405 drives the double-sided plates 407 to slide on the surface of the groove 413 of the connecting plate 403 until the double-sided plates 407 are completely in contact with the surface of the groove 413 of the connecting plate 403. This achieves the effect of improving the stability of the slide rod 405, preventing the control valve body 1 from being affected by external force and shaking when the operator uses the control valve body 1. This would prevent the slide rod 405 from sliding inside the connecting plate 403, and at the same time, the double-sided plates 407 from being affected and rotating, causing the control valve body 1 to shake. The surface of the irregular frame 404 is fixedly connected with a fixed A rod 408 is fixed, and a single-hole plate 410 is slidably connected to its arc surface. A plug rod 411 is fixedly connected to the surface of the single-hole plate 410. A fixing frame 401 has several circular grooves on its surface. The plug rod 411 is slidably connected to the surface of the circular grooves in the fixing frame 401. When the operator needs to adjust the height of the control valve body 1, they first pull the single-hole plate 410 to slide the plug rod 411 along the arc surface of the fixed rod 408 until the plug rod 411 is completely disengaged from the surface of the circular grooves in the fixing frame 401. At this point, the operator can pull the control valve body 1 to move the fixing frame 401. When the height of the control valve body 1 is adjusted to the appropriate position, the operator can push the single-hole plate 410 to slide the plug rod 411 along the arc surface of the fixed rod 408.Until the insertion rod 411 is inserted into the circular groove of the fixing bracket 401, the height of the control valve body 1 is adjusted. This prevents the control valve body 1 from being installed too low, which could cause operators to have to bend over or squat for extended periods, increasing operator fatigue and potentially affecting operational accuracy. One end of the fixing rod 408 is fixedly connected to a limit plate 409. The dimensions of the insertion rod 411 are adapted to the circular groove of the fixing bracket 401. When the operator needs to adjust the installation height of the control valve body 1, they first pull the single-hole plate 410 to move the insertion rod 411 onto the surface of the circular groove of the fixing bracket 401. The operator slides the single-hole plate 410, causing the insertion rod 411 to slide along the arc surface of the fixed rod 408 until the surface of the single-hole plate 410 is in contact with the limiting plate 409. At this point, the insertion rod 411 is completely disengaged from the circular groove of the fixed frame 401. The operator can then pull the control valve body 1 to move the fixed frame 401, thus preventing the single-hole plate 410 from being pulled off. This avoids situations where the operator pulls the single-hole plate 410 with excessive force when adjusting the installation height of the control valve body 1, causing the single-hole plate 410 to slip off the arc surface of the fixed rod 408 and requiring a second installation.

[0033] like Figure 6 and 7As shown, the dustproof device 5 includes an opening frame 51, which is fixedly connected to the upper surface of the control valve body 1. A rotating rod 52 is fixedly connected to the inner surface of the opening frame 51. A cover plate 53 is rotatably connected to the arc surface of the rotating rod 52. A positioning plate 57 is fixedly connected to the upper surface of the cover plate 53. A fixing block 54 is fixedly connected to the surface of the opening frame 51. A round rod 55 is rotatably connected to the surface of the fixing block 54. An operating plate 56 is fixedly connected to one end of the round rod 55. The operating plate 56 is slidably connected to the surface of the cover plate 53 and to the positioning plate 57. Two torsion springs 59 are sleeved on the arc surface of the rotating rod 52. The two ends of the torsion springs 59 are fixedly connected to the opening frame 51 and the cover plate 53, respectively. When the operator needs to use the connection port 8, the operator first rotates the operating plate 56 and slides it on the surface of the cover plate 53. The operating plate 56 drives the round rod 55 to rotate until the operating plate 56 is completely separated from the surface of the cover plate 53. At this time, the torque of the torsion springs 59 drives the cover plate 53 to rotate on the rotating rod 52. The arc surface rotates until the cover plate 53 is fully open. At this point, the operator can use the connection port 8 normally. This achieves the effect of automatic opening of the cover plate 53, while keeping the cover plate 53 in the open state, reducing the operator's operation steps and improving work efficiency. A single-sided plate 58 is fixedly connected to the surface of the cover plate 53. The size of the cover plate 53 is adapted to the size of the connection port 8. When the operator needs to use the connection port 8, the operator first releases the limit on the cover plate 53. Then, the torque of the torsion spring 59 drives the cover plate 53 to rotate on the arc surface of the rotating rod 52. The cover plate 53 drives the single-sided plate 58 to move until the single-sided plate 58 is in contact with the surface of the control valve body 1. At this point, the operator can use the connection port 8 normally. This achieves the effect of keeping the cover plate 53 in a vertical state, while maintaining a certain distance between the cover plate 53 and the control valve body 1. This allows the operator to easily rotate the cover plate 53 after using the connection port 8, improving the convenience of the device.

[0034] like Figure 8As shown, the auxiliary device 6 includes three operating levers 61, all of which are fixedly connected to the surface of the rotary controller 3. An arc-shaped plate 62 is slidably connected to the arc surface of each operating lever 61. A protective cover 63 is fixedly connected to the surface of each of the three arc-shaped plates 62. A second spring 64 is fitted onto the arc surface of each operating lever 61, with both ends of the second spring 64 fixedly connected to the rotary controller 3 and the arc-shaped plate 62, respectively. Three long rods 66 are fixedly connected to the surface of the rotary controller 3. Long grooves are formed on the surface of each long rod 66, and a double arc plate 67 is rotatably connected to the surface of the long grooves on the long rods 66. An L-shaped plate is fixedly connected to the surface of each arc plate 62. When the operator needs to use the knob 7, the operator first rotates the double-arc plate 67 on the surface of the long groove of the long rod 66 until the double-arc plate 67 no longer affects the movement of the L-shaped plate 68. Then, the operator pushes the protective cover 63, causing the arc plate 62 to slide on the arc surface of the operating rod 61. At this time, the second spring 64 is compressed, and the arc plate 62 drives the double-arc plate 67 to move. When the protective cover 63 is pushed to a certain position, the operator can rotate the double-arc plate 67 on the surface of the long groove of the long rod 66. When the double-arc plate 67 is rotated to a certain angle, the operator can release the protective cover 63. At this time, the rebound force of the second spring 64 causes the arc plate 62 to slide on the arc surface of the operating lever 61. The arc plate 62 drives the L-shaped plate 68 to move until the L-shaped plate 68 is in contact with the surface of the double arc plate 67. At this time, the operator can use the knob 7 normally, which achieves the effect of fixing the position of the protective cover 63 and making it convenient for the operator to adjust the parameters of the knob 7. The inner surface of the operating lever 61 is fixedly connected to the protective pad 65, which is slidably connected to the surface of the arc plate 62. When the operator opens the protective cover 63, the operator first presses the protective cover 63 to drive the arc plate 62 to slide on the arc surface of the operating lever 61. Sliding on the arc surface, the arc plate 62 drives the L-shaped plate 68 to move downwards until the L-shaped plate 68 is completely separated from the double arc plate 67. Then, the operator rotates the double arc plate 67 and slides it on the surface of the long groove of the long rod 66 until the double arc plate 67 no longer affects the movement of the L-shaped plate 68. Then, the operator releases the protective cover 63. At this time, the rebound force of the second spring 64 drives the arc plate 62 to slide on the arc surface of the operating rod 61 until the arc plate 62 is in contact with the protective pad 65. This achieves the effect of reducing the collision between the arc plate 62 and the operating rod 61, extending the service life of the operating rod 61 and improving the reliability of the device.

[0035] Working principle: When the operator needs to install the control valve body 1, the operator can first move the control valve body 1 to slide on the surface of the connecting plate 403 until the surface of the control valve body 1 is in contact with the square plate 402. At this time, the operator can push the round plate 406 to drive the slide rod 405 to slide within the irregular frame 404. At this time, the first spring 412 is stretched, and the slide rod 405 drives the double-sided plates 407 to slide on the surface of the sliding hole 414 of the connecting plate 403 until the double-sided plates 407 are completely disengaged from the connecting plate 403. Then, the operator can rotate the double-sided plates 407. When the double-sided plates 407 are rotated to a certain angle, the operator can release the round plate 406. At this time, the rebound force of the first spring 412 drives the round plate 406 to move. The round plate 406 drives the slide rod 405 to slide within the irregular frame 404. The slide rod 405 drives the double-sided plates 407 to slide on the surface of the groove 413 of the connecting plate 403 until the double-sided plates 407 and the groove 413 of the connecting plate 403 are in contact. With the surfaces fully aligned, when the operator needs to adjust the height of the control valve body 1, the operator first pulls the single-hole plate 410 to slide the insertion rod 411 on the arc surface of the fixed rod 408 until the surface of the single-hole plate 410 is in contact with the limiting plate 409. At this time, the insertion rod 411 is completely disengaged from the circular groove of the fixed frame 401. The operator can then pull the control valve body 1 to move the fixed frame 401. When the height of the control valve body 1 is pulled to the appropriate position, the operator can push the single-hole plate 410 to slide the insertion rod 411 on the arc surface of the fixed rod 408 until the insertion rod 411 is inserted into the circular groove of the fixed frame 401. This achieves the effect of facilitating the operator's disassembly of the control valve body 1 and avoiding problems during the use of the control valve body 1. Because the connection of the control valve body 1 is relatively complex, the operator needs to use different tools, which increases the operator's working time and labor costs, thus improving the practicality of the device.

[0036] When the operator needs to use the connection port 8, the operator first rotates the operating plate 56 and slides it on the surface of the cover plate 53. The operating plate 56 drives the round rod 55 to rotate until the operating plate 56 is completely separated from the surface of the cover plate 53. At this time, the torque of the torsion spring 59 drives the cover plate 53 to rotate on the arc surface of the rotating rod 52. The cover plate 53 drives the single-sided plate 58 to move until the single-sided plate 58 is in contact with the surface of the control valve body 1. At this time, the cover plate 53 is fully opened, and the operator can use the connection port 8 normally. This achieves the effect of preventing dust from falling into the connection port 8. It avoids the situation where dust accumulates inside the connection port 8 when the control valve body 1 is not used for a long time, which would cause poor contact of the connection port 8 when the operator needs to use it. This improves the practicality of the device.

[0037] When the operator needs to use knob 7, firstly, the operator rotates the double-arc plate 67 on the surface of the long groove of the long rod 66 until the double-arc plate 67 no longer affects the movement of the L-shaped plate 68. Then, the operator pushes the protective cover 63, causing the arc plate 62 to slide on the arc surface of the operating rod 61. At this time, the second spring 64 is compressed, and the arc plate 62 drives the double-arc plate 67 to move. When the protective cover 63 is pushed to a certain position, the operator can rotate the double-arc plate 67 on the surface of the long groove of the long rod 66. When the double-arc plate 67 is rotated to a certain angle, the operator can release the protective cover 63. At this time, the rebound force of the second spring 64 causes the arc plate 62 to slide on the arc surface of the operating rod 61, and the arc plate 62 drives the L-shaped plate 68 to move until the L-shaped plate 68 is in contact with the surface of the double-arc plate 67. At this time, the operator can use knob 7 normally. When the operator opens the protective cover 63, the operator first presses the protective cover 63 to cause the arc plate 62 to slide on the arc surface of the operating rod 61. The arc plate 62 causes the L-shaped plate 68 to move downwards until the L-shaped plate 68 is completely separated from the double arc plate 67. Then the operator rotates the double arc plate 67 to slide on the surface of the long groove of the long rod 66 until the double arc plate 67 no longer affects the movement of the L-shaped plate 68. Then the operator releases the protective cover 63. At this time, the rebound force of the second spring 64 causes the arc plate 62 to slide on the arc surface of the operating rod 61 until the arc plate 62 is in contact with the protective pad 65. This achieves the effect of reducing the accidental contact of the knob 7, and avoids the operator accidentally rotating the knob 7 when using the rotary controller 3, which would change the parameters of the control valve body 1 and cause the control valve body 1 to malfunction, thus improving the safety of the device.
