Description

Technical Field

[0001] The present invention relates to the field of valve technology, and in particular to a large-scale fluorine-lined valve for high-risk media with high reliability and a use method thereof. Background Art

[0002] With the rapid development of petrochemical industry, the treatment of large-scale high-risk corrosive media has become a key challenge. Fluorine-lined valves are fully lined with fluoroplastics in key parts such as the inner cavity of the valve body, valve core and valve disc to ensure that the medium has no direct contact with the metal part, thereby greatly extending the service life of the valve and improving safety. They are widely used in corrosive media pipelines in the chemical, petroleum and pharmaceutical industries, especially in the treatment of highly corrosive media such as sulfuric acid, hydrochloric acid and hydrofluoric acid. Existing fluorine-lined valves have certain defects in sealing performance, temperature adaptability and adjustment performance. Fluorine-lined materials have good corrosion resistance, but there is a risk of leakage in sealing performance compared to metal valves. The temperature resistance range of fluorine-lined materials is narrow and cannot adapt to high or low temperature environments. In high temperature environments, fluorine-lined materials will become brittle, reducing the service life of the valve. Due to structural defects, the flow regulation is not smooth enough under small opening conditions, affecting the control accuracy of the system.

[0003] 1. Patent document CN115929924B discloses a negative pressure resistant fluorine lined butterfly valve. The above patent prevents the valve seat sealing surface from being squeezed, worn or damaged by the outer circle sealing surface of the valve plate for a long time, thereby ensuring the sealing of the valve. However, the above patent cannot eliminate and utilize the pressure fluctuations in the transportation of high-risk media.

[0004] 2. Patent document CN110360361B discloses a fluorine-lined valve. The above patent realizes that the fluorine-lining layer is difficult to deform and shift under the influence of frequent opening and closing of the valve core or medium flow, and the adhesion is very reliable, which ensures the integrity of the fluorine-lining layer, making the valve durable and having a long service life. The adhesion reliability of the fluorine-lining layer is very high, but the above patent cannot realize the function of automatically adjusting the valve flux.

[0005] 3. Patent document CN117722527B discloses a fluorine-lined ball valve. The above patent realizes that the early warning rod and the early warning plate emit intermittent impact sounds under the reciprocating impact action, thereby warning the staff, indicating that the sealing ring is severely worn and needs to be replaced. Therefore, the sealing performance between the valve stem and the valve body is guaranteed by timely replacement of the sealing ring. However, the above patent cannot achieve the function of maintaining the operation of the valve when the valve core inside the valve is damaged.

[0006] 4. Patent document CN113898758B discloses a high-sealing fluorine-lined ball valve. The above patent realizes that when the valve disc is subjected to a tilting force, the valve stem does not squeeze the sealing device, thereby avoiding the formation of a gap between the valve stem and the sealing device, which leads to leakage, improves the sealing of the valve, and extends the service life of the valve. However, the above patent cannot realize the function of controlling the valve flux when the valve fails.

[0007] In summary, the above patents cannot achieve the function of eliminating and utilizing the pressure fluctuations in the transportation of high-risk media, cannot achieve the function of automatically adjusting the valve flux, cannot achieve the function of maintaining the operation of the valve when the valve core inside the valve is damaged, and cannot achieve the function of controlling the valve flux when the valve fails, resulting in damage to pipelines and equipment caused by pressure fluctuations, impact on the flow rate of the medium, reduced transportation efficiency, inaccurate and uneven flux adjustment, inaccurate flow control, increased energy consumption, reduced sealing performance due to valve core corrosion, environmental pollution, valve failure and reduced quality of the delivered finished product; To this end, the present application proposes a large-scale fluorine-lined valve for high-risk media with high reliability and a method of using the same, which can eliminate and utilize pressure fluctuations in the transportation of high-risk media, automatically adjust the valve flux, maintain the operation of the valve when the valve core inside the valve is damaged, and control the valve flux when the valve fails.

[0030] Working principle: when the high-risk medium flows through the valve, the pressure sensor 20 detects the pressure generated when the high-risk medium flows through the valve. Before the data reaches the preset value, the controller 5 controls the fixer 9 to cancel the fixation of the rotating blade 8. The rotating blade 8 rotates under the drive of the high-risk medium to slow down the flow rate of the medium. The rotation of the rotating blade 8 drives the connecting shaft connected to the rotating blade 8 to rotate. The kinetic energy of the high-risk medium is converted into electrical energy through the rotation of the connecting shaft and stored in the conversion box 7. During the high-risk medium transportation process, the flux of the valve needs to be adjusted. The controller 5 controls the operation of the power motor 6, adjusts the speed of the power motor 6 through the reducer 27, and transmits the kinetic energy to the telescopic shaft 10.

Under the detection of the moving distance by the displacement sensor 35, the emergency module 3 is moved to ensure the accuracy of the valve flux adjustment; When high-risk media passes through the fluorine-lined valve, the outer valve core 19 is flushed. Long-term flushing may cause leakage, poor circulation and valve failure of the fluorine-lined valve. The outer valve core 19 is damaged, and the pressure sensor 20 monitors the pressure changes on the inner valve core 18. After receiving the information, the controller 5 compares the pressure information with the information transmitted by the pressure sensor 20 when the outer valve core 19 is intact and when there is no outer valve core 19, and determines that the outer valve core 19 is damaged and affects the normal operation of the valve. The controller 5 controls the power motor 6 to connect with the emergency module 3, and the power motor 6 drives the driving gear 31 to rotate, driving the substances in the reaction chamber 34 to react. Ferrous sulfide is arranged inside the reaction chamber 34. and dilute sulfuric acid, and the ferrous sulfide is pushed to contact with the dilute sulfuric acid by the pushing gear 31, and the reaction generates gas, so that the reaction chamber 34 expands, and drives the support rod 32 installed on its outer wall to push the inner valve core 18 to fit the outer valve core 19, and the controller 5 controls the fixer 9 to fix the rotating blade 8, adjusts the angle of the rotating blade 8, and reduces the flow rate of the medium that contacts the emergency module 3 through the rotating blade 8, thereby reducing the flux of the valve, and the controller 5 controls the power motor 6 to drive the telescopic shaft 10 to move the emergency module 3, and monitors the pressure on the emergency module 3 in real time through the pressure sensor 20, thereby reducing the flux of the medium passing through the sinking and floating valve, and at the same time, the controller 5 sends a warning to the management personnel through emails and other means; When the emergency module 3 fails and the inner valve core 18 and the outer valve core 19 are corroded by high-risk media, the controller 5 controls the dynamic ring 23 to move and engage with the static ring 24, squeezes the pipe entering the connecting port 2, and reduces the flux of the valve.
