Description

Technical Field

[0001] This invention belongs to the field of valve device technology, and specifically relates to an insulated multi-degree-of-freedom actuator applicable to high-pressure valves. Background Technology

[0002] Valves are pipeline accessories used to open and close pipelines, control flow direction, and regulate and control the parameters of the transported medium. Based on their function, they can be classified into shut-off valves, check valves, regulating valves, etc. Valves are control components in fluid transport systems, possessing functions such as shut-off, regulation, flow diversion, backflow prevention, pressure stabilization, flow splitting, or pressure relief. Valves used in fluid control systems range from the simplest shut-off valves to the various valves used in extremely complex automated control systems, with a wide variety of types and specifications. A valve actuator is an automatic control device used to receive signals from a control system and drive valves to open, close, or regulate flow to precisely control the transport of fluid media. It converts electrical, pneumatic, or hydraulic energy into mechanical motion to automate valve operation and is widely used in industries such as chemical engineering, water treatment, and HVAC. Valve actuators convert electrical energy into mechanical energy, using an electric motor to drive valve movement, replacing manual operation. Control methods include remote, automatic, or programmed control. The movement process is precisely defined by parameters such as stroke and torque. Electric valve actuators typically consist of a motor, reduction gear, transmission mechanism, control system, position feedback, and protection devices, offering advantages such as high control precision, stable thrust, and easy long-distance signal transmission.

[0003] During long-term operation, impurities will accumulate on the inner walls of the pipes on the valve. If these impurities are not cleaned in time, they will affect the normal flow rate of the liquid and the cleanliness of the pipe, which is detrimental to the safe use of the device. In addition, in low-temperature environments, the density and viscosity of the fluid will increase, leading to a decrease in flow rate and affecting the accuracy of flow measurement. It may also cause a decline in the performance of the flow sensor on the valve, thereby affecting the measurement accuracy of the flow meter on the valve. Summary of the Invention

[0004] The purpose of this invention is to provide an insulated multi-degree-of-freedom actuator suitable for high-pressure valves, in order to solve the technical problem that during long-term operation of the pipeline on the valve, impurities will accumulate on the inner wall of the pipeline, which will affect the normal flow rate of the liquid and the cleanliness of the pipeline, thus hindering the safe use of the device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: Insulated multi-degree-of-freedom actuators suitable for high-pressure valves include: A first pipe and a second pipe, which are connected by a telescopic pipe; A flow regulating mechanism includes a first handle on a first pipe, the bottom of the first handle extending to a drive wheel, the drive wheel and the driven wheel being connected by a first conveyor belt, one end of the driven wheel being fixed to a first lead screw, and the upper and lower ends of the first lead screw being helically driven by a first slider and a second slider that move in the same direction. The first slider and the moving block are connected by a first swing rod, and a flow sensor is installed at one end of the moving block, while a flow meter is connected to the other end of the moving block via a wire on the first telescopic rod. A gear plate is fixedly installed at one end of the second slider, and a gear disk meshes with the outer wall of the gear plate. One end of the gear disk abuts against and adheres to the fixed disk.

[0006] Furthermore, the fixed disk and the gear disk are respectively provided with corresponding center holes and through holes. The two ends of the first swing rod are mounted on the first slider and the moving block by means of rotational connection. The moving block is connected with a sliding groove along the length direction of the inner wall of the first pipe. The first slider and the second slider are both connected with guide grooves along the height direction of the inner wall of the first pipe.

[0007] Furthermore, the fixed disk is installed on the side wall of the first pipe by an embedded fixing method, the outer edge of the gear disk is provided with a rotating groove connected to the first pipe, the through holes are distributed in a ring array on the fixed disk and the gear disk, and the center hole and the through hole are respectively provided with a first guide groove and a second guide groove placed inside the first pipe.

[0008] Furthermore, it also includes an execution drive mechanism, which includes a second rotating handle on the second pipe, a first rotating shaft on the second rotating handle connected to a rotating baffle placed on the inner wall of the second pipe, and the first rotating shaft and the second rotating shaft are connected by a second conveyor belt.

[0009] Furthermore, the bottom of the second rotating shaft is connected to a second lead screw extending into the interior of the second pipe. The upper and lower ends of the second lead screw are helically driven by a third slider and a fourth slider. One end of the third slider is connected to the push rod via a second swing rod. The push rod and the extension end of the second pipe side wall are connected by a compression spring. The push rod and the cleaning brush are fixedly connected by a crossbeam. The cleaning brush is ring-shaped and has bristles attached by an adhesive method. The cleaning brush has a limit groove connected along the length of the inner wall of the second pipe.

[0010] Furthermore, both ends of the second swing rod are mounted on the third slider and the push rod by means of rotational connection. The bottom end of the fourth slider is connected to the side wall of the second pipe by the second telescopic rod, and both ends of the fourth slider are equipped with U-shaped rods by brackets. The outer wall of the U-shaped rods movably abuts against the rotating plate, and one end of the rotating plate is movably connected to the inner wall of the second pipe by the third rotating shaft.

[0011] Furthermore, a third guide groove is formed between the rotating plate and the bottom of the inner wall of the second pipe, and a rotating cavity connected to the rotating plate is formed between the protrusions at both ends of the U-shaped rod. As the U-shaped rod moves up and down, the rotating plates on the third rotating shafts at both ends rotate in the same direction under the action of moving contact.

[0012] Furthermore, the bottoms of both the first and second pipes are connected to the electric slider via support columns. The bottom of the electric slider is equipped with a matching electric slide rail, and the top of the electric slide rail is concave and fixedly connected to the base plate.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: (1) In this invention, in order to ensure that the flow meter can detect the normal flow rate of liquid in a low-temperature environment, the first handle can drive the rotation of the drive wheel during rotation. Under the mechanical transmission, it can drive the rotation of the first lead screw. With the help of the screw transmission effect, the first slider and the second slider move downward synchronously. During the downward movement of the second slider, it can drive the gear disk on the gear plate to rotate. During the rotation of the gear disk, the through hole on the gear disk is offset from the through hole on the fixed disk, and the through holes are closed. The center hole on the gear plate and the fixed disk is always open. In this way, the flow rate is increased by reducing the liquid flow area. In addition, when the first slider moves downward, the flow sensor moves towards the initial flow direction of the liquid by means of the rotation connection of the first swing rod. Under the condition that other conditions remain unchanged, the reduction of the pipe length will increase the liquid velocity, thereby increasing the liquid flow rate by shortening the liquid inflow end distance. By combining the reduction of the flow distance and the reduction of the liquid flow area, the detection effect caused by the adjustment of low temperature is compensated, which effectively improves the accuracy of the flow meter data detection on the pipeline and improves the practicality of the device.

[0014] (2) In this invention, when the installation pipe is connected to other pipes, the length of the pipe is generally fixed and cannot be adjusted accordingly, which affects the stability of the connection with the external pipe. By setting a telescopic pipe between the first pipe and the second pipe, and cooperating with the electric slide rail connected to the electric slider at the bottom of the first pipe and the second pipe, the distance between the first pipe and the second pipe at both ends can be adjusted, so as to adaptably install and connect with external pipes of different sizes, effectively improving the applicability of the device.

[0015] (3) In this invention, when cleaning the inside of the pipe, firstly, the transmission component connected to the second rotating handle acts as the actuator of the valve, which can control the drive to rotate the baffle, thereby adjusting the liquid flow rate. It can also transmit power to the second screw through the conveyor belt. During the rotation of the second screw, the third and fourth sliders can move up and down synchronously with the help of the screw transmission. During the movement of the third slider, the cleaning brush on the push rod can move back and forth with the help of the rotation connection of the second swing rod. The compression spring on the push rod has a corresponding positioning and guiding function, which can also help the push rod return to its original position automatically during the movement, ensuring the stability of the push rod movement. In addition, during the upward movement of the fourth slider, the rotating plate rotates synchronously upward on the third rotating shaft through the active contact between the U-shaped rod and the rotating plate. At this time, the flow rate can be increased due to the reduced flow area between the rotating plate and the third guide groove at the bottom of the inner wall of the pipe. Thus, the impurities that fall into the inner wall of the pipe after cleaning can be more easily flushed away. The design is reasonable, ensuring the cleanliness of the inside of the pipe. It has a high degree of automation, is easy for personnel to operate, and improves work efficiency. Attached Figure Description

[0019] 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.

[0020] Reference manual attached Figure 1 -Appendix Figure 7 As shown, an insulated multi-degree-of-freedom actuator suitable for high-pressure valves includes: a first pipe 1 and a second pipe 2, which are connected by a telescopic pipe 3; a flow regulating mechanism 4, which includes a first handle 5 on the first pipe 1, the bottom of the first handle 5 extending to the driving wheel 6, the driving wheel 6 and the driven wheel 7 being connected by a first conveyor belt 41, one end of the driven wheel 7 being fixed to a first lead screw 8, and the first lead screw 8 having a first slider 9 and a second slider 10 that move in the same direction at both ends. The first slider 9 and the moving block 11 are connected by the first swing rod 12, and a flow sensor is installed at one end of the moving block 11, and a flow meter 14 is connected to the other end by a wire on the first telescopic rod 13; a gear plate 15 is fixedly installed at one end of the second slider 10, and a gear disk 16 is meshed with the outer wall of the gear plate 15, and one end of the gear disk 16 abuts against and adheres to the fixed disk 17.

[0021] When the moving block 11 is pushed, it works in conjunction with the first telescopic rod 13 on the flow sensor. This ensures that the moving block 11 can move horizontally normally and that the signal from the flow sensor can be effectively transmitted to the flow meter 14 through the wire. In addition, the fixed end of the first telescopic rod 13 extends to the inner wall of the first pipe 1, so that the first pipe 1 has a good supporting connection to it and ensures the stability of the structural connection.

[0022] To ensure the flow meter can detect the normal flow rate of liquids even in low-temperature environments, the first handle 5, during rotation, drives the drive wheel 6 to rotate. Under mechanical transmission, this drives the first lead screw 8 to rotate. Utilizing the helical transmission effect, the first slider 9 and the second slider 10 move downwards synchronously. During the downward movement of the second slider 10, it drives the gear disk 16 on the gear plate 15 to rotate. During the rotation of the gear disk 16, the through hole 19 on the gear disk 16 is misaligned with the through hole 19 on the fixed plate 17, causing the through holes 19 to close. Meanwhile, the center hole 18 on the gear plate 15 and the fixed plate 17 remain aligned. When in the open state, the flow rate is increased by reducing the flow area of ​​the liquid. In addition, when the first slider 9 moves downward, the flow sensor moves in the initial flow direction of the liquid by means of the rotational connection of the first swing rod 12. Under the condition that other conditions remain unchanged, the reduction of the pipe length will increase the liquid velocity, thereby increasing the liquid flow rate by shortening the liquid inlet end distance. By combining the reduction of flow distance and the reduction of liquid flow area, the detection effect caused by low temperature is compensated, which effectively improves the accuracy of the flow meter data detection on the pipeline and improves the practicality of the device.

[0023] The flow sensors are electromagnetic flow sensors, all model d8545. Their working principle is based on Faraday's law of electromagnetic induction. They measure flow velocity by generating an induced electromotive force through the cutting of magnetic lines of force by conductive liquid. They are unaffected by changes in medium pressure, viscosity, and density, and have high measurement accuracy.

[0024] Specifically, the first rotating handle 5 and the second rotating handle 21 can be adapted to be a drive motor. Driving through an electric mechanism is a conventional technical means for those skilled in the art, and will not be described in detail here, nor will it affect the effective implementation of the technical solution of the present invention.

[0025] When the installation pipe is connected to other pipes, the length of the pipe is generally fixed and cannot be adjusted accordingly, which affects the stability of the connection with the external pipe. By setting a telescopic pipe 3 between the first pipe 1 and the second pipe 2, and cooperating with the electric slide rail 39 connected to the electric slider 38 at the bottom of the first pipe 1 and the second pipe 2, the distance between the two ends of the first pipe 1 and the second pipe 2 can be adjusted, so as to adaptably install and connect with external pipes of different sizes, effectively improving the applicability of the device.

[0026] The center hole 18 and through hole 19 on the fixed disk 17 and the gear disk 16 are the same size and their initial positions are the same. This allows the liquid to flow normally inside the pipe. When the gear disk 16 rotates, the through holes 19 are staggered, while the center holes 18 on both remain in the same position. When the gear disk 16 rotates, the center holes 18 on both are always open, and the size of the holes is not affected by obstruction.

[0027] Specifically, the fixed disk 17 and the gear disk 16 are respectively provided with a corresponding center hole 18 and a through hole 19. The two ends of the first swing rod 12 are mounted on the first slider 9 and the moving block 11 by means of rotational connection. The moving block 11 is connected with a sliding groove along the length direction of the inner wall of the first pipe 1. The first slider 9 and the second slider 10 are both connected with guide grooves along the height direction of the inner wall of the first pipe 1.

[0028] The fixed disk 17 is installed on the side wall of the first pipe 1 by an embedded fixing method. The outer edge of the gear disk 16 is provided with a rotating groove connected to the first pipe 1. The through holes 19 are distributed in a ring array on the fixed disk 17 and the gear disk 16, and the center hole 18 and the through hole 19 are respectively provided with a first guide groove and a second guide groove placed inside the first pipe 1.

[0029] Specifically, the insulated multi-degree-of-freedom actuator applicable to high-pressure valves also includes an actuation drive mechanism 20. The actuation drive mechanism 20 includes a second handle 21 on the second pipe 2. A first shaft 22 on the second handle 21 is connected to a rotating baffle 23 placed on the inner wall of the second pipe 2. The first shaft 22 and the second shaft 24 are connected by a second conveyor belt 25.

[0030] The bottom of the second rotating shaft 24 is connected to a second lead screw 26 extending into the second pipe 2. The upper and lower ends of the second lead screw 26 are screwed with a third slider 27 and a fourth slider 28. One end of the third slider 27 is connected to the push rod 30 through the second swing rod 29. The push rod 30 is connected to the side wall extension end of the second pipe 2 through a compression spring 31. The push rod 30 and the cleaning brush 32 are fixedly connected through a crossbeam 33. The cleaning brush 32 is ring-shaped and has bristles attached by adhesive fixation. The cleaning brush 32 is connected with a limit groove along the length of the inner wall of the second pipe 2.

[0031] Furthermore, the first handle 5 and the second handle 21 on the pipeline are equipped with insulating sleeves, which can provide corresponding insulation for the device, thus effectively improving the safety of the device itself. Moreover, for the technical solution of the multi-degree-of-freedom actuator of the present invention, the rotating baffle 23 connected to the second handle 21 can achieve flow regulation through vertical rotation, while the transmission component connected to the first handle 5 can achieve flow regulation through horizontal rotation. Together with the rotating plate 36 connected to the third shaft 37, a swing flow regulation component is formed, thereby realizing a multi-degree-of-freedom actuator.

[0032] Specifically, both ends of the second swing rod 29 are mounted on the third slider 27 and the push rod 30 by means of rotational connection. The bottom end of the fourth slider 28 is connected to the side wall of the second pipe 2 by the second telescopic rod 34. Both ends of the fourth slider 28 are equipped with U-shaped rods 35 by brackets. The outer wall of the U-shaped rods 35 movably abuts against the rotating plate 36. One end of the rotating plate 36 is movably connected to the inner wall of the second pipe 2 by the third rotating shaft 37.

[0033] When cleaning the inside of the pipe, firstly, the transmission component connected to the second handle 21 acts as a valve actuator, controlling the drive to rotate the baffle 23, thereby adjusting the liquid flow rate. It also transmits power to the second lead screw 26 via a conveyor belt. During the rotation of the second lead screw 26, the screw drive simultaneously moves the third slider 27 and the fourth slider 28 up and down. During the movement of the third slider 27, the rotational connection of the second swing rod 29 allows the cleaning brush 32 on the push rod 30 to move back and forth. Furthermore, the compression spring 31 on the push rod 30 is equipped with corresponding... The positioning and guiding function also helps the push rod 30 to automatically return to its original position during movement, ensuring the stability of the push rod 30's movement. In addition, during the upward movement of the fourth slider 28, the rotating plate 36 rotates synchronously upward on the third rotating shaft 37 through the active abutment between the U-shaped rod 35 and the rotating plate 36. At this time, the flow rate can be increased due to the reduced flow area between the rotating plate 36 and the third guide groove at the bottom of the inner wall of the pipe. In this way, the impurities that fall into the inner wall of the pipe after cleaning can be more easily flushed away. The design is reasonable, ensuring the cleanliness of the inside of the pipe, with a high degree of automation, easy for personnel to operate, and improved work efficiency.

[0034] Reference manual attached Figure 6 and attached Figure 8 The connection between the second lead screw 26 and the push rod 30 can be replaced by the second rotating shaft 24 and the cam 40. During rotation, the second rotating shaft 24 drives the cam 40 to rotate synchronously. During rotation, the cam 40 engages with the push rod 30 on the compression spring 31, thereby driving the cleaning brush 32 on the push rod 30 to perform horizontal reciprocating motion. During the movement of the cleaning brush 32, the bristles perform the corresponding cleaning work, and the bristles are attached to the cleaning brush 32 by an adhesive method. A third guide groove is formed between the rotating plate 36 and the bottom of the inner wall of the second pipe 2. A rotating cavity is formed between the protrusions at both ends of the U-shaped rod 35 and connected to the rotating plate 36. As the U-shaped rod 35 moves up and down, the rotating plate 36 on the third rotating shaft 37 at both ends rotates in the same direction under the action of moving contact. The setting of the rotating cavity can provide corresponding activity space for the movement of the U-shaped rod 35 and the rotating plate 36, ensuring their free rotation.

[0035] The bottoms of both the first pipe 1 and the second pipe 2 are connected to the electric slider 38 via support columns. The bottom of the electric slider 38 is equipped with a matching electric slide rail 39. The top of the electric slide rail 39 is concave and fixedly connected to the base plate.

[0036] The electric slide rail 39 and electric slider 38 mentioned above can also be replaced by electric push rod assembly or motor screw assembly. These are conventional technical means for those skilled in the art, so they will not be described in detail. Moreover, the concave top of the electric slide rail 39 can prevent the transmission components from deviating in position during movement, thereby improving the stability of the device.
