[0012] Compared with the prior art, the present invention has the following beneficial effects: The liner-type corrosion-resistant ceramic structure regulating valve uses a ceramic valve core with a built-in cleaning brush core. When the valve core is opened to the maximum, the brush plate is driven by water flow to rotate, thereby cleaning impurities at the valve core opening, reducing the probability of valve core blockage, thereby reducing the vibration caused by the reduction of the water port cross-sectional area, and thereby reducing the probability of the ceramic bushing in the regulating valve breaking; The inner-lined corrosion-resistant ceramic structure regulating valve utilizes a brush core in combination with a spring. Under the influence of water flow vibration, the spring is squeezed to achieve the up and down movement of the brush core. At the same time, the brush core cooperates with an airflow sensor to transmit the exhaust and air intake state of the brush core when it moves up and down to a controller through the airflow sensor, thereby realizing the detection of the vibration state of the pipeline system. When the vibration intensifies to a frequency that is likely to cause the ceramic bushing to rupture, a signal is fed back to the controller to perform corresponding actions, thereby maintaining the service life of the ceramic bushing, improving the intelligence and reliability of the regulating valve, and enhancing the adaptability of the regulating valve to adverse environments; The lined corrosion-resistant ceramic structure regulating valve uses a solenoid valve in conjunction with a water guide plate. When the vibration frequency of the fluid transmitted to the regulating valve is within a range that can damage the ceramic bushing of the regulating valve, the solenoid valve is activated to release the connection with the water guide plate. The water guide plate slides downward under the action of gravity, cutting off the connection between the regulating valve and the pipeline, and guiding the fluid to be discharged out of the pipeline, thereby reducing the adverse effect of fluid vibration on the ceramic bushing, maintaining the service life of the regulating valve, and improving the reliability of the regulating valve and the safety of the pipeline. The invention relates to a lined, corrosion-resistant ceramic structure regulating valve, which utilizes a rubber bushing in combination with a ceramic bushing to absorb the vibration of the ceramic bushing transmitted to the ceramic bushing through a pipe body within a certain range, thereby increasing the service life of the ceramic bushing. The cooperation of a brush core mechanism and a water guide plate mechanism is utilized to detect the vibration state of the regulating valve over a large range in the regulating valve, and close the water guide plate when the vibration frequency is within a range that can damage the ceramic bushing, thereby changing the direction of water flow to reduce vibration and reduce damage to the ceramic bushing in the regulating valve, thereby further improving the reliability of the regulating valve, maintaining the service life of the regulating valve, and at the same time improving the safety of the delivery pipeline.

[0017] Working principle: Normally, the water pipeline is connected to the regulating valve through the cut-off flange 311 on one side of the flow breaker 3. The water flows into the valve body 1 through the flow breaker 3, flows through the ceramic bushing 112, and then enters the valve core 2 from the circular through hole on the surface of the ball body 202. The water flows through the brush core 21, pushing the water flow plate 212. While the water flow plate 212 drives the connecting rod 211 to rotate, the brush group 213 on the front of the water flow plate 212 scrapes off the impurities in the through hole on the surface of the ball body 202. Then the water flows through the ceramic bushing 112 on the other side and leaves the regulating valve. The personnel can hold the handle 22 and rotate it counterclockwise for 90 degrees to block the pipeline connection. The handle 22 drives the core shell 20 to rotate counterclockwise together, and the circular through hole of the ball body 202 rotates to the front and back of the shell 10. The internal passage of the shell 10 is blocked. The handle 22 can also be held and rotated counterclockwise for 45 degrees to reduce the opening of the regulating valve, thereby controlling the flow rate. When the water flow carries some solid impurities, the vibration generated when it flows in the pipe is greater than that of the water flow with very little solid impurities. At this time, when the water flow is about to flow to the breaker 3, the vibration generated by the water flow is transmitted to the breaker 3 through the pipe, and then transmitted to the vibration sensor 317 through the breaker 3. After sensing the vibration, the vibration sensor 317 feeds back the signal to the controller 41 through the wire. After receiving the feedback signal, the controller 41 determines that the vibration frequency exceeds the tolerance range of the ceramic bushing 112, and controls the electromagnet assembly 315 to be energized. After the electromagnet assembly 315 is energized, an electromagnetic force is generated to attract the plug rod 316 to move in the forward direction, and at the same time, the spring fixedly connected to the front of the plug rod 316 is stretched. When the plug rod 316 reaches the limit baffle 314, the plug rod 31 6 is disconnected from the water guide plate 33, and the water guide plate 33 slides downward under the influence of gravity until the bottom of the stopper 331 contacts the top of the main body 31. At this time, the water guide plate 33 completely blocks the connection between the flow cutter 3 and the valve body 1, and the water flow carrying impurities is discharged out of the pipe through the water guide groove 332, completing the flow cut-off process, so that it cannot enter the valve body 1, which has an adverse effect on the ceramic bushing 112, thereby maintaining the service life of the regulating valve. After solving the problem of water cleanliness in the cut-off water channel, the personnel turn off the controller 41 and lift the water guide plate 33 upward until the blind hole on the front of the water guide plate 33 rises to be coaxial with the plug rod 316. The plug rod 316 is reset under the action of the spring and re-enters the blind hole to complete the fixation of the water guide plate 33. Then the controller 41 is restarted to resume work; When the regulating valve is in the open state and water flows through, if there are too many impurities blocking most of the through holes of the ball body 202 and the brush core 21 cannot be completely cleaned, the water inlet area will be reduced, which will cause more intense vibration near the ball body 202, and the frequency of the up and down movement of the brush core 21 will increase, which will cause the up and down movement frequency of the top seat 214 to increase. The air chamber formed by the top of the top seat 214 and the inside of the top shaft 203 increases the frequency of air extraction and exhaust through the ventilation pipe of the air flow sensor 207. The air flow sensor 207 feeds back the air flow signal to the controller 41. After receiving the signal, the controller 41 determines that the vibration frequency near the ball body 202 has increased. In order to prevent long-term vibration from damaging the ball body 202, the electromagnet assembly 315 is energized to execute the aforementioned water guide plate 33 to cut off the flow, and then continue the cut-off process until the personnel have eliminated the abnormality and reconnected.
