Description

Technical Field

[0001] The utility model relates to the technical field of valve control, in particular to a valve remote control driving device. Background Art

[0002] The existing valve remote control drive devices mainly include four types: pneumatic, hydraulic, electric, and electro-hydraulic. The device needs to use a cylinder, hydraulic cylinder or hydraulic motor, electric motor to convert internal energy or electrical energy into mechanical energy to achieve the purpose of opening and closing the valve; in order to remotely display the opening and closing status of the valve, it is often necessary to install an electronic limit switch on the valve remote control drive device. When used in hazardous gas locations, liquid immersion and other scenarios, explosion-proof or IP68 and above protection level limit switches are required to meet the stringent use requirements. These devices are often expensive and require multiple intermediate components to realize the drive and control of the valve, which increases the number of failure points, increases energy consumption, and reduces the reliability of the drive device.

[0003] Reference Figure 1 and Figure 2 In the prior art, there is a pneumatic valve remote control drive device, and the working principle is as follows: in the initial state, the valve switch module is in the disconnected state, and the compressed air is sent to the A chamber of the pneumatic driver 2' through the solenoid valve 1', pushing the piston 3' to both sides of the cylinder, and the rack of the piston 3' drives the rotating shaft 4' to rotate, so that the valve plate of the valve rotates to the closed position, and at the same time, the limit switch 5' on the driver is turned to the closed position. The cable feeds back the state signal of the limit switch 5' to the valve state display panel 6', indicating that the valve is in the closed state, and at the same time outputs the valve closed state to a remote location. After the system receives the remote control valve opening command signal, the valve switch module 7' is powered on, the solenoid valve 1' is energized, and the compressed air is sent to the B chamber of the pneumatic driver 2' through the solenoid valve 1', pushing the piston 3' to the center of the cylinder. The rack of the piston 3' drives the shaft 4' to rotate in the opposite direction, so that the valve plate of the valve rotates to the open position, and at the same time, the limit switch 5' on the driver is turned to the open position. The cable feeds back the status signal of the limit switch 5' to the valve status display panel 6', indicating that the valve is in the open state, and outputs the valve opening state to a remote location.

[0004] The above-mentioned driving device has the risk of leakage due to the compressed air being transmitted through pipelines, and the energy is converted and transmitted multiple times, resulting in high energy consumption. Utility Model Content

[0032] In addition, the technical features involved in different embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0033] Referring to Figures 3 to 6 , as a valve remote control driving device provided by an embodiment of the present utility model, it includes a first bracket 1, a second bracket 2, an electric winch 3, a fixed pulley set 4, a wire rope set 5, and a guide pulley set 6. An adapter 61 is provided at the center of the guide pulley set 6, and the adapter 61 is connected to the valve stem 8. A traction pin 62 is provided on the outer edge of the guide pulley set 6. The electric winch 3 is arranged on the first bracket 1, the fixed pulley set 4 is arranged on the second bracket 2, the fixed pulley set 4 is arranged adjacent to the guide pulley set 6. The wire rope set 5 includes a first wire rope 51 and a second wire rope 52. One end of the first wire rope 51 is fixed on the traction pin 62, and the other end is wound around the fixed pulley set 4 along the first direction on the outer edge of the guide pulley set 6 and then fixed on the electric winch 3. One end of the second wire rope 52 is fixed on the traction pin 62, and the other end is wound around the fixed pulley set 4 along the second direction on the outer edge of the guide pulley set 6 and then fixed on the electric winch 3. The first direction is opposite to the second direction.

[0034] When the electric winch 3 rotates in the first direction or the second direction, through the traction of the first wire rope 51 or the second wire rope 52, the rotation of the valve stem 8 is realized, and the opening and closing of the valve are realized. There is no need to externally connect compressed air, the structure is simple, there are few moving parts, few failure points, and high reliability. There is no multiple energy conversion, which is more energy-saving and environmentally friendly.

[0035] Specifically, the guide wheel set 6 is provided with a first guide groove and a second guide groove, and the fixed pulley set 4 is provided with a first connection groove and a second connection groove. The first steel wire rope 51 is located in the first guide groove and the first connection groove, and the second steel wire rope 52 is located in the second guide groove and the second connection groove. Through the first guide groove, the second guide groove, the first connection groove and the second connection groove, the first steel wire rope 51 and the second steel wire rope 52 can be misaligned and connected to avoid mutual entanglement and interference. The base of the guide wheel set 6 is firmly fixed on the pipeline flange with bolts of appropriate strength. Among them, in order to ensure the balanced force of the steel wire rope, it is necessary to ensure that the axles of the electric winch 3, the fixed pulley set 4 and the guide wheel set 6 are all parallel. The guide grooves of the guide wheel set 6 are evenly distributed with balls, and their function is to reduce the friction coefficient of the steel wire rope. Lubricating grease should be applied to all rotating and sliding parts to ensure smooth movement.

[0036] Among them, when the length of the steel wire rope group 5 is too long or a turn is required, the fixed pulley set 4 can be added; when the steel wire rope group 5 needs to be transmitted over a relatively long distance, a steel wire rope protection pipe can be added to prevent the steel wire rope group 5 from falling and deviating.

[0037] Further, a first limit block 53 is provided on the first steel wire rope 51, and a first sensor 11 is provided on one side of the first bracket 1. A second limit block 54 is provided on the second steel wire rope 52, and a second sensor 12 is provided on the other side of the first bracket 1.

[0038] Specifically, a signal processing module is provided in the electric winch 3, and the signal processing module is electrically connected to the first sensor 11. The first limit block 53 moves upward with the first steel wire rope 51 until it contacts the first sensor 11 and sends out a closing signal. This signal is fed back to the signal processing module of the electric winch 3. The signal processing module controls the power module to cut off the power supply of the motor, and the motor stops rotating. The signal processing module also feeds back to a distance that the valve is closed through a signal cable. The signal processing module is electrically connected to the second sensor 12. The second limit block 54 moves upward with the second steel wire rope 52 until it triggers the second sensor 12 and sends out an opening signal. This signal is fed back to the signal processing module of the electric winch 3. The signal processing module controls the power module to cut off the power supply of the motor, and the motor stops rotating. The signal processing module also feeds back to a distance that the valve is opened through a signal cable. The valve remote control driving device further includes an indicating rod 63. One end of the indicating rod 63 is connected to the traction pin 62, and the other end is connected to the center of the guide wheel set 6. Through the position of the indicating rod 63, the state of the valve can be intuitively reflected.

[0039] Furthermore, the valve remote control driving device further includes a driving handwheel 7 which is mounted on the first bracket 1, and the driving handwheel 7 can drive the electric winch 3 to rotate. In case of a power system failure, the valve can be operated emergently by manually rotating the driving handwheel 7. Among them, the current opening and closing state of the valve can be judged by observing the position of the indicating rod 63, and then the rotation direction of the driving handwheel 7 can be selected.

[0040] Furthermore, there are multiple guide pulley groups 6, and each guide pulley group 6 is connected to the corresponding valve stem 8 through an adapter 61, and the electric winch 3 drives the multiple guide pulley groups 6 to rotate simultaneously. Through flexible combination, synchronous linkage of multiple valves can be achieved.

[0041] The working principle of the valve remote control driving device in this embodiment is as follows:

[0042] Closing the valve: Assume that the valve is currently in the fully open state. The power supply provides energy for closing the remote control valve. After receiving the remote control valve closing signal, the electric winch 3 controls the motor to start rotating clockwise through its internal signal processing module, drives the winch to rotate clockwise to tighten the first steel wire rope 51 and loosen the second steel wire rope 52 at the same time. The first steel wire rope 51 bypasses the fixed pulley group 4 and the guide pulley group 6, and then drives the valve stem 8 to rotate counterclockwise. When the indicating rod 63 rotates to form a 90-degree angle with the pipeline, the first limit block 53 moves upward along with the first steel wire rope 51 to contact the first sensor 11 and send out a closing signal. This signal is fed back to the signal processing module of the electric winch 3. The signal processing module controls the power supply module to cut off the power supply of the motor, and the motor stops rotating. The signal processing module simultaneously feeds back to a distance through the signal cable that the valve has been closed.

[0043] Opening the valve: The power supply provides energy for opening the remote control valve. After receiving the remote control valve opening signal, the electric winch 3 controls the motor to start rotating counterclockwise through its internal signal processing module, drives the winch to rotate counterclockwise to tighten the second steel wire rope 52 and loosen the first steel wire rope 51 at the same time. The second steel wire rope 52 bypasses the fixed pulley and the guide pulley group 6, and then drives the valve stem 8 to rotate clockwise. When the valve rod rotates to form a 0-degree angle with the pipeline, the second limit block 54 moves upward along with the second steel wire rope 52 to trigger the second sensor 12 and send out an opening signal. This signal is fed back to the signal processing module of the electric winch 3. The signal processing module controls the power supply module to cut off the power supply of the motor, and the motor stops rotating. The signal processing module simultaneously feeds back to a distance through the signal cable that the valve has been opened.

[0044] The embodiments of this specific implementation manner are all preferred embodiments of the present invention, and do not limit the protection scope of the present invention accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present invention should be covered within the protection scope of the present invention.
