[0037] The regulating valve as a commonly used instrument control device has a wide application in the petrochemical industry or high polymer material production industry. The regulating valve can realize the on-off control and flow regulation control of fluid, and has many characteristics such as high precision, wide regulation range, rapid response and the like.

[0038] In the actual use process of regulating valve for on-off control and flow regulation control of fluid, some actuators in the regulating valve will act. However, for the purpose of structure simplification, cost control or maintenance convenience, the existing regulating valve products expose the part of the actuator which needs to act to the external environment in the design.

[0039] If the part of the actuator exposed to the external environment acts when the operating personnel are working on site, the fingers or other parts of the operating personnel may be mechanically squeezed or pressed, so that the safety of the regulating valve is low.

[0040] In addition, the working environment of the regulating valve is often harsh, that is, in a high temperature, high humidity, high corrosive or dusty industrial environment. In a long time of work, the part of the actuator exposed to the external environment will inevitably be damaged by the external environment, so that the service life of the regulating valve is low.

[0041] Based on the above considerations, the application designs a regulating valve device, which comprises a valve body, an actuating mechanism, a driving mechanism and a protective component. The valve body comprises a valve seat and a valve core. The valve seat is internally provided with a fluid passage. The valve core is arranged in the valve seat and is configured to be movable relative to the valve seat. The valve core is used to control the opening and closing of the fluid passage by moving itself.

[0042] The actuating mechanism comprises a frame and a movable component. The frame is fixedly connected to the valve seat. The movable component is movably connected to the frame. The valve core is fixedly connected to the movable component. The movable component is configured to be movable relative to the frame and to drive the valve core to move. The driving mechanism is connected to the movable component. The driving mechanism is used to drive the movable component to move. The protective component is connected to the frame. The protective component is arranged to cover the outside of at least part of the actuating mechanism.

[0043] The protective component can isolate the outside of the actuating mechanism. On the one hand, when the actuating mechanism is in operation, the protective component can effectively prevent the operator from contacting the actuating mechanism with the limbs, thereby avoiding the injury of the operator and improving the safety of the regulating valve device. On the other hand, the protective component can also shield particles or dust in the external environment, thereby reducing the risk of damage to the actuating mechanism by the external environment and improving the service life of the regulating valve device.

[0044] Fig. 1 A structural schematic diagram of a regulating valve device provided by some embodiments of the application is shown in the following figure, Fig. 2 A three-dimensional structural schematic diagram of a protective component of a regulating valve device provided by some embodiments of the application is shown in the following figure, Fig. 3 An exploded structural schematic diagram of a protective component of a regulating valve device provided by some embodiments of the application is shown in the following figure.

[0045] Reference Figs. 1 to 3 The application provides a regulating valve device. The regulating valve device comprises a valve body 10, an actuating mechanism 20, a driving mechanism 30 and a protective component 40. The valve body 10 comprises a valve seat 11 and a valve core 12. The valve seat 11 is internally provided with a fluid passage 111. The valve core 12 is arranged in the valve seat 11 and is configured to be movable relative to the valve seat 11. The valve core 12 is used to control the opening and closing of the fluid passage 111 by moving itself.

[0046] The actuating mechanism 20 comprises a frame 21 and a movable component 22. The frame 21 is fixedly connected to the valve seat 11. The movable component 22 is movably connected to the frame 21. The valve core 12 is fixedly connected to the movable component 22. The movable component 22 is configured to be movable relative to the frame 21 and to drive the valve core 12 to move. The driving mechanism 30 is connected to the movable component 22. The driving mechanism 30 is used to drive the movable component 22 to move. The protective component 40 is connected to the frame 21. The protective component 40 is arranged to cover the outside of at least part of the actuating mechanism 20.

[0047] The regulating valve device is used for on-off control and flow regulating control of fluid. Exemplarily, the valve body 10 can include an inlet and an outlet, and the fluid passage 111 is communicated between the inlet and the outlet, and the valve body 10 is connected to the pipeline through the inlet and the outlet.

[0048] Optionally, the fluid passage 111 can be but is not limited to a straight line type, an L type or a T type structure, which can be selected and optimized according to the use scene.

[0049] As an example, the spool 12 cooperates with the valve seat 11 to achieve on-off control of the fluid. That is, the spool 12 can be in a first position and a second position inside the valve seat 11, when the spool 12 is in the first position, the spool 12 can cut off the fluid passage 111, thereby cutting off the fluid passage; when the spool 12 is in the second position, the spool 12 can remove the cut-off of the fluid passage 111, so that the fluid can pass through the regulating valve device to restore the fluid flow of the pipeline.

[0050] As an example, the spool 12 cooperates with the valve seat 11 to also achieve flow regulating control of the fluid. That is, the position of the spool 12 inside the valve seat 11 is different, the flow rate of the fluid in the fluid passage 111 is also different, and the spool 12 changes the position of the spool 12 inside the valve seat 11 by moving itself, thereby achieving flow regulating control of the fluid.

[0051] Optionally, the spool 12 can be but is not limited to a spherical spool 12, a plunger type spool 12 or a butterfly valve plate, which can be matched according to the passage structure.

[0052] Optionally, the valve seat 11 and the spool 12 can be but are not limited to made of low carbon steel, copper, magnesium alloy, stainless steel, titanium and titanium metal, nickel and nickel metal, or aluminum and anodized material.

[0053] The valve seat 11 and the spool 12 can be made of the same material, or can be made of different materials.

[0054] As an example, the valve seat 11 and the spool 12 are made of the same material, which can simplify the preparation process and reduce the cost.

[0055] In some examples, a sealing structure such as a sealing ring or a sealing gasket is provided between the spool 12 and the valve seat 11 to ensure the sealing performance of the regulating valve device when switching between on-off states.

[0056] The frame body 21 is a basic structure for supporting the movable part 22 and transmitting motion.

[0057] The frame body 21 can be detachably connected to the valve seat 11 or integrally arranged on the valve seat 11. The frame body 21 can be directly connected to the valve seat 11 or limited on the valve seat 11 by other components. For example, the connection mode of the frame body 21 and the valve seat 11 can be welding, bolt connection, clamping, riveting or bonding, but is not limited thereto.

[0058] Optionally, the frame body 21 can be made of cast steel or aluminum alloy, but is not limited thereto, to ensure the balance between strength and weight reduction.

[0059] The movable component 22 can be movably connected to the frame body 21 by a sliding block or a guide rail structure, but is not limited thereto, and has the ability to move relative to the frame body 21 in a predetermined direction.

[0060] Optionally, the movable component 22 can be a rod-shaped structure, a block-shaped structure or a plate-shaped structure, but is not limited thereto.

[0061] The valve core 12 can be detachably connected to the movable component 22 or integrally arranged on the movable component 22. The valve core 12 can be directly connected to the movable component 22 or limited on the movable component 22 by other components. For example, the connection mode of the valve core 12 and the movable component 22 can be welding, bolt connection, clamping, riveting or bonding, but is not limited thereto.

[0062] The driving mechanism 30 is connected to the movable component 22 and acts on the movable component 22 to drive it to move.

[0063] The driving mechanism 30 can be a servo motor, an electric cylinder, a pneumatic cylinder or a hydraulic cylinder, but is not limited thereto.

[0064] For example, the driving mechanism 30 can be connected to the movable component 22 by a connecting rod, a screw rod transmission, a gear and a rack or a direct connection mode to drive the movable component 22 to move linearly or rotate.

[0065] The protection component 40 can be detachably connected to the frame body 21 or integrally arranged on the frame body 21. The protection component 40 can be directly connected to the frame body 21 or limited on the frame body 21 by other components. For example, the connection mode of the protection component 40 and the frame body 21 can be welding, bolt connection, clamping, riveting or bonding, but is not limited thereto.

[0066] For example, the protection component 40 can be a cover arranged on the outside of part of the actuator 20 or a cover arranged on the outside of all the actuators 20.

[0067] Optionally, the protection component 40 can be a shell structure or a box structure.

[0068] As an example, the shielding component 40 can be made of, but not limited to, transparent polycarbonate, engineering plastic or metal mesh shell and the like, which can not only provide the necessary physical isolation for the actuator 20, but also maintain the visibility of the actuator 20 located inside.

[0069] The shielding component 40 can be a cuboid structure, a cylindrical structure or other surrounding structure to shield the key moving parts of the actuator 20.

[0070] The configuration of the shielding component 40 can also be selected according to the local conditions. For example, in the scene where the internal running state needs to be observed, transparent polycarbonate or acrylic material can be selected, and an anti-fog and anti-scratch coating can be provided on the surface. In the case of electromagnetic interference shielding requirement, a metal mesh structure can be used, and an electromagnetic discharge path can be provided through a grounding wire. In outdoor or dusty environments, sealing rubber strips, dust filters or positive pressure air curtain systems can also be provided on the shielding component 40 to prevent particles from entering. The connection mode of the shielding component 40 can also be selected from threaded connection, buckle connection, magnetic installation or quick-release lock, which is convenient for maintenance and replacement.

[0071] The shielding component 40 of the above technical solution can isolate the outside of the actuator 20. On the one hand, when the actuator 20 is in action, it can effectively prevent the operator from contacting the actuator 20, thereby avoiding the injury of the operator and improving the safety of the control valve device. On the other hand, the shielding component 40 can also shield particles or dust in the external environment, reducing the risk of damage to the actuator 20 by the external environment and improving the service life of the control valve device.

[0072] As an example, in the actual use process of the control valve device for on-off control and flow regulation control of fluid, when the actuator 20 performs a series of actions, the shielding component 40 can form an isolation barrier at the physical level to prevent the operator from directly contacting the high-speed or high-torque moving parts due to accidental touch or proximity during equipment operation, thereby significantly reducing the probability of accidents such as pinching and crushing, and improving the intrinsic safety of on-site operation and the safety protection level of the equipment.

[0073] In the operating environment of the control valve device, there are often a large amount of dust, particles, corrosive gases or liquids and other pollution sources. The exposed actuator 20 is easily eroded by pollutants in long-term work, leading to seal aging, mechanism jamming or transmission failure. The shielding component 40 can effectively shield the entry of external pollutants into the moving area of the actuator 20, slow down the wear and corrosion process, thereby prolonging the service life of the control valve device and reducing the maintenance frequency and cost.

[0074] In some embodiments, there is a gap between the shielding component 40 and the actuator 20 to reduce the influence on the original function of the actuator 20.

[0075] In some embodiments, the movable component 22 comprises a pneumatic actuator 221 connected to the frame 21, a push rod 222 connected to an action end of the pneumatic actuator 221, and a connecting piece 223 fixedly connecting the valve core 12 to the push rod 222. The driving mechanism 30 is configured to provide gas to the pneumatic actuator 221 to drive the pneumatic actuator 221 to move the valve core 12 through the push rod 222. The connecting piece 223 is located outside the pneumatic actuator 221, and the protection component 40 is arranged outside the connecting piece 223.

[0076] For example, the pneumatic actuator 221 can comprise a shell having a sealed cavity, a diaphragm connected to an inner wall of the shell and dividing the sealed cavity into a first cavity and a second cavity, and a spring arranged in the first cavity and connected to the diaphragm and the inner wall of the shell. The push rod 222 is connected to a side of the diaphragm opposite to the spring. The spring is configured to apply a force to the diaphragm in a direction close to the spring. The shell is further provided with a gas port communicating with the first cavity. The driving mechanism 30 is connected to the gas port and configured to provide gas to the first cavity.

[0077] When the driving mechanism 30 inputs gas to the first cavity, the gas provides a pressure to the diaphragm to overcome the elastic force of the spring and move the diaphragm in a direction away from the spring. When the driving mechanism 30 extracts the gas from the first cavity, the pressure provided by the gas decreases, and the elastic force of the spring can drive the diaphragm to move in a direction close to the spring. The movement of the diaphragm can drive the valve core 12 to move through the push rod 222 to achieve on-off control and flow regulation control of the fluid.

[0078] The valve core 12 is fixedly connected to the push rod 222 through the connecting piece 223 to facilitate the maintenance of the regulating valve device. For example, when the regulating valve device needs to be disassembled for maintenance or repair, the movable component 22 and the valve body 10 can be quickly separated through the connecting piece 223, thereby facilitating the subsequent maintenance or repair of the operating personnel.

[0079] In addition, other functional components can be arranged on the connecting piece 223 to improve the use convenience of the regulating valve device. For example, an identification component can be arranged on the connecting piece 223. The operating personnel can intuitively determine the current on-off state of the regulating valve device or the current flow control state of the regulating valve device through the position of the identification component.

[0080] Therefore, it can be understood that, whether based on the maintenance convenience of the regulating valve device or the use convenience of the regulating valve device, the connecting piece 223 needs to be exposed to the external environment during the design of the regulating valve device to achieve the above effects.

[0081] However, when the actuator 20 performs the action, the connecting piece 223 will also move accordingly, and the connecting piece 223 is exposed to the external environment. If there is an operator working on the spot, the operator's fingers and other parts may be mechanically squeezed or crushed, which reduces the safety of the regulating valve.

[0082] In addition, the working environment of the regulating valve is often harsh, that is, in a high-temperature, high-humidity, high-corrosion or multi-dust industrial environment. In a long time of work, the connecting piece 223 exposed to the external environment will inevitably be damaged by the external environment, which reduces the service life of the regulating valve.

[0083] The technical solution can protect the connecting piece 223 with a high safety risk by covering the connecting piece 223 with the protection component 40, which can improve the safety and service life of the regulating valve device while reducing the amount of material of the protection component 40 to reduce costs.

[0084] In some embodiments, the protection component 40 includes a frame part 41 and two plate parts 42, which are independently formed. The frame part 41 has a first opening and a second opening at both ends along the first direction X, and one of the two plate parts 42 covers the first opening, and the other covers the second opening. The frame part 41 and the two plate parts 42 form an accommodation space, and at least part of the actuator 20 is accommodated in the accommodation space.

[0085] The modular design of the frame part 41 and the plate part 42 makes the manufacturing, transportation and installation process of the protection component 40 more efficient. The independent forming of the frame part 41 and the plate part 42 facilitates separate replacement or maintenance, reducing overall maintenance costs. At the same time, this structure facilitates flexible adjustment of the size or position of the protection component 40 according to the length or installation direction of the actuator 20, enhancing the versatility and site compatibility.

[0086] The plate part 42 can be directly connected to the frame part 41, or can be limited on the frame part 41 by other components.

[0087] Alternatively, the frame part 41 and the two plate parts 42 can be connected by, but not limited to, threaded fastening, buckle locking, magnetic attraction quick installation and the like.

[0088] In some embodiments, the frame part 41 can adopt a telescopic structure, that is, the frame part 41 body is composed of two or more telescopic sleeves, which can adapt to actuators 20 with different lengths or stroke requirements, and further reduce the volume of the protection component 40 during transportation and storage.

[0089] In some embodiments, the active component 22 comprises a pneumatic actuator 221 connected to the frame 21, a push rod 222 connected to an acting end of the pneumatic actuator 221, and a connecting member 223 connecting the valve core 12 to the push rod 222. The driving mechanism 30 is configured to provide gas to the pneumatic actuator 221 to drive the pneumatic actuator 221 to move the valve core 12 through the push rod 222. The connecting member 223 is located outside the pneumatic actuator 221 and is accommodated in the accommodating space.

[0090] In some embodiments, the protective component 40 has an accommodating space in which at least part of the actuating mechanism 20 is accommodated. The protective component 40 has a double-layer structure, i.e., the protective component 40 comprises a first structural layer and a second structural layer, the first structural layer is connected to a side of the second structural layer facing the accommodating space, the first structural layer has a greater strength than the second structural layer, and the second structural layer has a greater flexibility than the first structural layer.

[0091] The first structural layer is located inside the protective component 40 and has a greater strength, which can provide better structural support for the protective component 40 and improve the structural stability of the protective component 40. The second structural layer is located outside the protective component 40 and has a greater flexibility, which can further reduce the risk of injury to the operator when contacting the protective component 40.

[0092] In some embodiments, the second structural layer is a flexible structure.

[0093] In some embodiments, the protective component 40 further comprises a reinforcing member 43 connected to the frame portion 41 and the plate portion 42, and the reinforcing member 43 covers at least part of the connecting edge of the frame portion 41 and the plate portion 42.

[0094] For example, the reinforcing member 43 can cover part of the connecting edge of the frame portion 41 and the plate portion 42, or can cover the entire connecting edge of the frame portion 41 and the plate portion 42.

[0095] The number of reinforcing members 43 can be one or more, where more than two means two or more.

[0096] The reinforcing member 43 is configured to enhance the connection strength and structural rigidity between the frame portion 41 and the plate portion 42, and to ensure that the regulating valve device can maintain a stable assembly state of the protective component 40 under long-term operation, vibration impact, or complex environment.

[0097] The reinforcing member 43 covers at least part of the connecting edge of the frame part 41 and the plate part 42, effectively shielding and protecting the joint area from dust, moisture, etc. entering the accommodation space through the tiny gap while ensuring a simple appearance. At the same time, the reinforcing member 43 can be provided with reinforcing ribs, reinforcing ribs or porous structure to enhance the overall mechanical rigidity and provide additional mounting fulcrums, such as for fixing signal wire clamps or card seats and other accessories.

[0098] Optionally, the reinforcing member 43 can be connected to the frame part 41 and the plate part 42 by means of bolt fixation, welding, riveting, adhesive bonding or embedded clamping, etc.

[0099] The structure of the reinforcing member 43 can be a U-shaped collar, an L-shaped reinforcing plate or a groove type pressing strip, etc., whose cross section is adapted to the joint area of the frame part 41 and the plate part 42.

[0100] For example, when the frame part 41 is a rectangular structure and the plate part 42 is a flat plate structure, the reinforcing member 43 can be an edge covering type L-shaped reinforcing plate, one side of which is attached to the frame edge and the other side covers the edge of the plate part 42. For a cylindrical frame structure, a semi-ring or ring-shaped hoop reinforcing ring can be used, which is buckled to the outer periphery of the connecting joint.

[0101] Optionally, the reinforcing member 43 can be made of high-strength engineering plastics, aluminum alloy, stainless steel or composite fiber, etc., which can be configured according to different working conditions to balance the corrosion resistance, strength, weight and cost, etc.

[0102] For example, for scenes with special requirements such as explosion-proof and corrosion-proof, an epoxy corrosion-resistant coating, a ceramic coating or a conductive shielding layer can also be sprayed on the surface of the reinforcing member 43 to improve its comprehensive performance in harsh environments.

[0103] The above technical solution realizes the structural reinforcement and connection protection of the frame part 41 and the plate part 42 by setting the reinforcing member 43, which helps to improve the overall structural stability and reliability of the protection component 40.

[0104] In some embodiments, the reinforcing member 43 is arranged in the accommodation space. It can reduce the risk of damage to the reinforcing member 43 by the external environment, thereby further improving the reliability of the protection component 40.

[0105] In some embodiments, the frame part 41 comprises a first part 411 and a second part 412, which are independently formed respectively. The first part 411 comprises a first plate body 4111 and two second plate bodies 4112, which are connected to the two ends of the first plate body 4111 along the second direction Y respectively and are bent relative to the first plate body 4111 along the direction close to the accommodation space. The second part 412 comprises a third plate body 4121 and two fourth plate bodies 4122, which are connected to the two ends of the third plate body 4121 along the second direction Y respectively and are bent relative to the third plate body 4121 along the direction close to the accommodation space. The second plate bodies 4112 and the fourth plate bodies 4122 are connected in abutment, the first plate body 4111 and the second plate body 4112 are arranged opposite to each other along the third direction Z, and the first direction X, the second direction Y and the third direction Z are perpendicular to each other in pairs.

[0106] For example, the first plate body 4111 and the two second plate bodies 4112 cooperate with each other to form a C-shaped structure, and the third plate body 4121 and the two fourth plate bodies 4122 cooperate with each other to form a C-shaped structure.

[0107] For example, the second plate body 4112 can be bent relative to the first plate body 4111 at an angle of 90° or close to 90°, and the fourth plate body 4122 can be bent relative to the third plate body 4121 at an angle of 90° or close to 90°.

[0108] Optionally, the first plate body 4111, the second plate body 4112, the third plate body 4121 and the fourth plate body 4122 can all be rectangular plate bodies or square plate bodies.

[0109] The above technical solution can further improve the assembly flexibility of the protection component 40 by dividing the frame part 41 into the first part 411 and the second part 412 with complementary structures.

[0110] In some embodiments, at least one of the first plate body 4111, the second plate body 4112, the third plate body 4121 and the fourth plate body 4122 is provided with a reinforcing rib to improve the structural strength of the protection component 40.

[0111] In some embodiments, at least one of the first plate body 4111, the second plate body 4112, the third plate body 4121 and the fourth plate body 4122 is provided with a positioning hole or an assembly auxiliary mark to improve the assembly consistency and the abutment accuracy.

[0112] In some embodiments, the first plate body 4111, the second plate body 4112, the third plate body 4121 and the fourth plate body 4122 can be, but are not limited to, arc-shaped plates, bent plates or corrugated plate structures.

[0113] In some embodiments, a rubber sealing strip, a foam tape or a glue injection sealing line can be embedded between the abutting edges of the second plate body 4112 and the fourth plate body 4122 to prevent external dust, water vapor and the like from entering, so as to improve the sealing performance of the protection component 40.

[0114] In some embodiments, the first plate body 4111 and the two second plate bodies 4112 are integrally formed.

[0115] On the one hand, the first plate body 4111 and the two second plate bodies 4112 do not need to be connected through an additional connection process, simplifying the manufacturing process flow. At the same time, compared with connecting the first plate body 4111 and the two second plate bodies 4112 through an additional connection process, the first plate body 4111 and the two second plate bodies 4112 in an integrated structure have higher structural strength.

[0116] In some embodiments, the third plate body 4121 and the two fourth plate bodies 4122 are integrally formed.

[0117] On the one hand, the third plate body 4121 and the two fourth plate bodies 4122 do not need to be connected through an additional connection process, simplifying the manufacturing process flow. At the same time, compared with connecting the third plate body 4121 and the two fourth plate bodies 4122 through an additional connection process, the third plate body 4121 and the two fourth plate bodies 4122 in an integrated structure have higher structural strength.

[0118] In some embodiments, the protection component 40 further includes a plurality of reinforcing members 43, including a first reinforcing member 43a and a second reinforcing member 43b. The first reinforcing member 43a is connected to the second plate body 4112 and the plate portion 42, and covers at least part of the connecting edge of the second plate body 4112 and the plate portion 42. The second reinforcing member 43b is connected to the fourth plate body 4122 and the plate portion 42, and covers at least part of the connecting edge of the fourth plate body 4122 and the plate portion 42. The overall structural stability and reliability of the protection component 40 can be further improved.

[0119] The structural shape and size of the first reinforcing member 43a and the second reinforcing member 43b can be the same or different.

[0120] As an example, the structural shape and size of the first reinforcing member 43a and the second reinforcing member 43b are the same.

[0121] In some embodiments, the first reinforcing member 43a is connected to the second reinforcing member 43b, which can further improve the overall structural stability and reliability of the protection component 40.

[0122] Exemplarily, the first reinforcing member 43a can be directly connected to the second reinforcing member 43b, or can be indirectly connected to the second reinforcing member 43b through other components.

[0123] In some embodiments, the first reinforcing member 43a and the second reinforcing member 43b are integrally formed.

[0124] In one aspect, the first reinforcing member 43a and the second reinforcing member 43b are connected without an additional connection process, simplifying the manufacturing process flow. Meanwhile, compared with connecting the first reinforcing member 43a and the second reinforcing member 43b through an additional connection process, the first reinforcing member 43a and the second reinforcing member 43b in an integral structure have higher structural strength.

[0125] In some embodiments, the reinforcing member 43 covers at least part of the connecting edge of the second plate body 4112 and the fourth plate body 4122.

[0126] In some embodiments, the protection component 40 is detachably connected to the frame body 21. This connection manner enables the protection component 40 to be conveniently detached or replaced without affecting the installation state of the actuator 20, improving the maintainability and operation flexibility of the control valve device.

[0127] In some embodiments, the protection component 40 is provided with a through hole or an observation window, which can not only provide necessary physical isolation for the actuator 20, but also maintain the visibility of the actuator 20 located inside.

[0128] Exemplarily, the protection component 40 is a mesh shell.

[0129] In some embodiments, at least one of the first plate body 4111, the second plate body 4112, the third plate body 4121, and the fourth plate body 4122 is provided with a through hole or an observation window.

[0130] In some embodiments, the protection component 40 is provided with a relief opening for avoiding at least part of the actuator 20, so as to reduce the risk of interference between the protection component 40 and the actuator 20 and reduce the assembly difficulty of the protection component 40.

[0131] Exemplarily, the relief opening is a circular opening.

[0132] In some embodiments, at least one of the first plate body 4111, the second plate body 4112, the third plate body 4121, and the fourth plate body 4122 is provided with a relief opening.

[0133] In some embodiments, the second plate body 4112 and the fourth plate body 4122 are provided with a relief opening.

[0134] In some embodiments, the outer surface of the guard component 40 is provided with an electroluminescent layer, and the regulating valve device further comprises a control component connected to the movable component 22 and the electroluminescent layer, the control component being configured to apply an electrical signal to the electroluminescent layer during movement of the movable component 22 to drive the electroluminescent layer to emit light.

[0135] During movement of the movable component 22, the electroluminescent layer can emit light, so that the operator can intuitively determine that the movable component 22 is moving, thereby enabling the operator to better avoid risks.

[0136] For example, the control component can detect and obtain the motion state of the movable component 22, and apply an electrical signal to the electroluminescent layer when the movable component 22 moves to drive the electroluminescent layer to emit light.

[0137] For example, the control component can be, but is not limited to, an integrated microcontroller, a logic drive module, or an embedded sensor control unit.

[0138] Specifically, the control component can integrate a Hall sensor, a photoelectric encoder, or a contact type travel switch, etc. position detection device, to monitor the position or movement state of the movable component 22 in real time. When the movable component 22 is detected to be in a moving state, the control component will output a preset electrical signal (such as a driving voltage or a pulse signal) to the electroluminescent layer to make it emit light. The light emission mode can include continuous lighting, intermittent flashing, or intensity gradient, etc. as a visual prompt of the regulating valve device "in action"; when the movable component 22 stops moving, the control component stops signal output, so that the electroluminescent layer is extinguished, indicating that the device is in a static or stable state.

[0139] Optionally, the light emission color of the electroluminescent layer can be, but is not limited to, red, yellow, or blue, etc.
