Description

Technical Field

[0001] The invention relates to the technical field of butterfly valves, and in particular to a butterfly valve with a remote video monitoring function. Background Art

[0002] The butterfly valve is installed on the liquid pipeline and mainly plays the role of cutting off and throttling. The opening and closing part of the butterfly valve is a disc-shaped valve plate, which drives the valve plate to rotate around its own vertical axis in the valve body under the control of the valve stem, so as to achieve the purpose of opening and closing or adjustment. For the convenience of use, the valve stem is generally controlled to rotate by the drive motor of the electric actuator, and the drive motor can be used through remote control. After long-term use, the butterfly valve may cause leakage inside and outside the valve body due to factors such as liquid impact force and corrosion. The external leakage part is generally the connection surface between the valve and the pipeline, and the internal leakage part is generally the contact surface where the valve stem passes through the valve body. Whether it is internal or external leakage of the valve body, it is difficult to detect it in time.

[0003] A patent document with reference publication number CN117905891A discloses a remotely controlled butterfly valve, which is provided with a remote control system, utilizes the signal transmission operation between the remote control end and the signal transceiver end, and transmits the instruction to the equipment control module for controlling the opening and closing of the control cylinder and the drive motor, so that the butterfly valve can be remotely controlled and monitored during use so as to perform positioning and limiting operations in a timely manner, thereby improving the convenience of using the butterfly valve and eliminating the need for personnel to touch the butterfly valve itself.

[0004] However, the butterfly valves that can be remotely monitored in the prior art, such as the above-mentioned reference patent documents, can only be monitored and controlled by signal transmission, and cannot perform remote video monitoring when the valve is leaking.

The other side of the mounting plate is installed with a motor 232 for controlling the rotation of the gear 231. The motor 232 drives the gear 231 to rotate, thereby driving the middle cylinder 22 to rotate. When the middle cylinder 22 rotates, it drives the two cameras 4 installed on its side to move synchronously, so that the camera 4 can realize 360° horizontal rotation monitoring of the inside and outside of the sealing seat 2, wherein there is a gap between the camera 4 located inside the sealing seat 2 and the valve stem 211, and the two motors installed on the inner wall of the top seat 23 have a gap with the moving track of the camera 4, which will not hinder the movement of the camera 4; Further, such as Figure 6-10As shown, the edges of the outer circular surfaces at both ends of the fixed cylinder 3 are provided with a plurality of support rods 31 distributed in a circular array, and a slot 311 is provided on the outer end surface of each support rod 31, and a slider 1 312 is slidably connected inside the slot 311, and a spring 313 is connected between the slider 1 312 and the opposite surface of the slot 311, and a connecting rod 32 is movably hinged on the outer surface of the slider 1 312, and a slider 2 33 is movably hinged on the other end of the connecting rod 32, and a plurality of sliders 2 33 are movably connected to the outer circular surface of the camera 4 housing, and are distributed in a circular array, and a plurality of connecting rods 32 support and limit the camera 4, and a plurality of sliders 2 33 connect the camera 4, and the combination of the two makes The entire camera 4 is installed on the fixed cylinder 3, and the camera 4 is synchronously displaced with the rotation of the fixed cylinder 3 and the middle cylinder 22. During the use of the butterfly valve, due to the occasional instability of the fluid pressure, when the fluid pressure is unstable, it is easy to cause a certain vibration of the valve body, especially when a leakage occurs, the vibration of the valve body will be aggravated to a certain extent. By connecting a spring 313 between the card slot 311 and the opposite surface of the slider 312, the several connecting rods 32 used to support the camera 4 are more stable. The spring 313 can greatly weaken the vibration caused by the valve, thereby ensuring the stability of the camera 4 when installed and used, and ensuring that the real-time monitoring can transmit good image quality; Further, such as Figure 6 and Figure 7 As shown, an adjustment mechanism is also installed on the fixed cylinder 3, and the adjustment mechanism includes a micro cylinder 344 movably hinged on the bottom surface of the camera 4, which is used to adjust the deflection angle of the camera 4. Both end surfaces of the fixed cylinder 3 are provided with annular grooves 34, and one side wall of the annular groove 34 is a rack structure. The adjustment mechanism also includes a gear three 341 meshed in the annular groove 34, and the outer surface of the gear three 341 is connected to a carrier plate 342 through a rotating shaft. A carrier plate 342 driving the gear three 341 to rotate is installed on the top of the carrier plate 342. One end of the micro cylinder 344 is movably connected to the outer surface of the motor three 343 through a hinge, and the camera 4 itself can rotate to a certain angle for a multi-range Monitoring, by arranging a micro cylinder 344 on the rear side of the camera 4, the length of the output rod of the micro cylinder 344 can determine the deflection angle of the camera 4, so that when the monitoring range of the camera 4 is further increased, the micro cylinder 344 longitudinally adjusts the deflection angle of the camera 4, and the micro cylinder 344 can be used when the middle cylinder 22 is stationary or rotating, and cooperates with the middle cylinder 22 to adjust the horizontal direction of the camera 4, so as to realize the two cameras 4 to perform all-round real-time monitoring of the internal and external environment of the sealing seat 2, and can quickly and intuitively lock the fault point when leakage occurs, and then quickly deal with the fault to avoid pollution and loss caused by large amounts of liquid overflow.

[0023] In the third embodiment, a remote monitoring system is also installed inside the sealing seat 2. The remote monitoring system includes a controller and an electric regulator. Both the controller and the electric regulator are installed on the inner wall of the top seat 23. The electric regulator is electrically connected to the controller. The electric regulator is also electrically connected to the motor 215, the motor 232 and the micro cylinder 344 respectively. The electric regulator is mainly used to control the rotation direction, rotation speed, extension length of the output rod, etc. of the motor 215, the motor 232 and the micro cylinder 344. The controller is connected to the camera 4 and the microphone 5 for control respectively. The controller transmits the video image monitored by the camera 4 to the video display terminal in the monitoring room through the wireless communication device. The video image displayed by the video display terminal in the monitoring room, such as the computer, is used to determine whether the butterfly valve needs to be opened and closed. When the butterfly valve needs to be opened, the computer sends an instruction to the controller. The controller first controls the motor 215 to start, and the motor 215 drives the gear 214 to rotate. The gear 214 drives the gear ring 212 to rotate, thereby driving the valve stem 211 to rotate and controlling the valve plate to open the valve channel. When a leakage occurs, the pickup 5 first collects the leakage sound and then starts the motor 232 through the controller. The motor 232 drives the gear 231 to rotate, thereby driving the middle cylinder 22 to rotate. When the middle cylinder 22 rotates, it drives the two cameras 4 installed on its side to move synchronously, so that the camera 4 can perform 360° horizontal rotation monitoring of the inside and outside of the sealing seat 2, and the middle cylinder 22 can be rotated multiple times to drive the camera 4 to perform real-time monitoring. During the rotation of the middle cylinder 22, the micro cylinder 344 is started by the controller. The length of the output rod of the micro cylinder 344 can determine the deflection angle of the camera 4, so that when the monitoring range of the camera 4 is further increased, the micro cylinder 344 longitudinally adjusts the deflection angle of the camera 4. The micro cylinder 344 can be used when the middle cylinder 22 is stationary or rotating, and cooperates with the middle cylinder 22 to adjust the horizontal direction of the camera 4, thereby realizing the two cameras 4 to perform all-round real-time monitoring of the internal and external environment of the sealing seat 2.

[0024] When the above embodiment is working, in the process of using the butterfly valve, the video display terminal in the monitoring room, such as the video screen displayed on the computer, is used to determine whether the butterfly valve needs to be opened and closed. When the butterfly valve needs to be opened and closed, the computer sends instructions to the controller, and the controller first controls the motor 215 to open and close. The motor 215 drives the gear 214 to rotate, and the gear 214 drives the gear ring 212 to rotate, thereby driving the valve stem 211 to rotate and control the valve plate to open or close the valve channel; when a leak occurs on the outside of the butterfly valve, such as the connection surface between the valve and the pipeline, or when a leak occurs on the inside of the valve, such as the penetration position between the valve stem 211 and the sealing seat 2, the pickup 5 will first quickly collect and amplify the sound caused by the leak, and the controller controls the valve channel to be closed, and then transmits the sound to the computer through the controller control, and then starts the motor 232, and the motor 232 drives the gear 231 to rotate, thereby driving the middle cylinder 22 to enter. The middle cylinder 22 rotates, and the two cameras 4 installed on its side are driven to move synchronously when the middle cylinder 22 rotates, so that the camera 4 can perform 360° horizontal rotation monitoring on the inside and outside of the sealing seat 2, and the middle cylinder 22 is rotated multiple times to drive the camera 4 to perform real-time monitoring. During the rotation of the middle cylinder 22, the micro cylinder 344 is started by the controller. The length of the output rod of the micro cylinder 344 can determine the deflection angle of the camera 4, so as to further increase the monitoring range of the camera 4. The micro cylinder 344 longitudinally adjusts the deflection angle of the camera 4. The micro cylinder 344 can be used when the middle cylinder 22 is stationary or rotating, and cooperates with the middle cylinder 22 to adjust the horizontal direction of the camera 4, so as to realize the two cameras 4 to perform all-round remote real-time video monitoring of the internal and external environment of the valve, which can quickly and intuitively lock the fault point when leakage occurs, and then quickly handle the fault to avoid pollution and loss caused by large amounts of liquid overflow.
