Detailed Implementation

[0032] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0033] Example 1: As Figure 1 - Figure 9 As shown, the present invention provides a ball valve with automatic compensation function, including a filter mechanism 1, a leakage monitoring mechanism 2 fixedly connected to the bottom of the filter mechanism 1, and a drive mechanism 3 fixedly connected to the top of the filter mechanism 1.

[0034] The filtering mechanism 1 comprises a first valve body 101, a first shaft hole 102 is arranged on the top of the first valve body 101, a valve rod 103 is movably arranged on the inner wall of the first shaft hole 102, a positioning block 104 is fixedly arranged on the bottom of the valve rod 103, two fixed rings 105 are movably arranged on the inner wall of the first valve body 101, a first spring 106 is fixedly arranged on the outer wall of one side of each of the two fixed rings 105, a sealing ring 107 is fixedly arranged on the outer wall of one side of each of the two first springs 106, a valve ball 108 is arranged between the outer walls of the two sealing rings 107, the outer wall of the positioning block 104 is movably arranged in the valve ball 108, the outer wall of the valve ball 108 is movably arranged in the first valve body 101, a second valve body 109 is threadedly connected to the inner wall of the first valve body 101, a first filter screen 110 is fixedly arranged on the inner wall of the second valve body 109, a second shaft hole 111 is arranged on the outer wall of the first filter screen 110, a first rotating shaft 112 is movably arranged on the inner wall of the second shaft hole 111, a rotating paddle 113 is fixedly arranged on the outer wall of the first rotating shaft 112, a cleaning brush 114 is fixedly arranged on the outer wall of the first rotating shaft 112, the outer wall of one side of the cleaning brush 114 is in contact with the outer wall of one side of the first filter screen 110, a group of baffles 115 are fixedly arranged on the outer wall of the cleaning brush 114, a storage tank 116 is threadedly connected to the inner wall of the second valve body 109, a group of anti-skid convex points 117 are fixedly arranged on the outer wall of the storage tank 116, two second filter screens 118 are fixedly arranged on the inner wall of the storage tank 116, and a feeding port 119 is arranged on the top of the storage tank 116.

[0035] When the valve stem 103 rotates inside the first shaft hole 102, the lower positioning block 104 is driven to rotate, which drives the lower valve ball 108 to rotate, thereby changing the shape of the passage in the first valve body 101, realizing the opening or closing of the valve. The sealing ring 107 on both sides of the valve ball 108 is tightly attached to the valve ball 108 to avoid water leakage. When the temperature, pressure, flow and other factors in the pipeline change, or the sealing ring 107 is worn out due to long-term use, a gap will appear between the sealing ring 107 and the valve ball 108, causing the sealing performance of the valve to decrease. At this time, the first spring 106 is stretched to push the sealing ring 107 and the valve ball 108 tightly, ensuring that the sealing performance of the valve always remains at a high level, improving the stability and reliability of the production system. When the sealing ring 107 or the first spring 106 is damaged and cannot continue to work, the user only needs to remove the valve from the pipeline, rotate the second valve body 109 to remove it from the inside of the first valve body 101, and then rotate the valve stem 103 to drive the lower positioning block 104 to keep the first valve body 101 horizontal. At this time, the valve ball 108 inside the first valve body 101 can roll out, making it easy for the user to remove the two sealing rings 107 and related components for replacement. The disassembly process is convenient and fast, reducing maintenance costs and improving work efficiency. When the valve is in use, the water flow will first contact the first filter screen 110, which can effectively filter impurities in the water to prevent impurities from causing blockage and corrosion of the pipeline and equipment downstream, thereby prolonging the service life of the equipment. The water flow also drives the rotating paddle 113 to rotate. At this time, the first shaft 112 inside the rotating paddle 113 starts to rotate inside the second shaft hole 111, driving the cleaning brush 114 on the other side of the first filter screen 110 to rotate, brushing off the impurities accumulated on the surface of the first filter screen 110 to prevent impurities from reducing the filtering effect and efficiency of the first filter screen 110. When the cleaning brush 114 rotates, it will drive a group of baffles 115 to move. At this time, the blocked feed inlet 119 begins to emerge. The impurities driven by the cleaning brush 114 and the baffles 115 enter the storage tank 116 under the action of centrifugal force. The two arc-shaped second filter screens 118 inside the storage tank 116 form a narrow passage, which can prevent impurities from leaking from the inside of the storage tank 116. If the valve is closed and the rotating paddle 113 lacks water flow to drive it to a stationary state, the baffles 115 will reset the cleaning brush 114 and the first shaft 112 under the action of gravity, ensuring that there is always a baffle 115 located directly below to block the feed inlet 119 at the top of the storage tank 116, further preventing the possibility of impurities leaking. By collecting and storing filtered impurities, the possibility of blockage of the first filter screen 110 and the pipeline in front of it can be avoided, ensuring the continuous and stable operation of the equipment. When the storage tank 116 collects too much impurity, the user only needs to rotate the storage tank 116 to remove it from below the second valve body 109 for replacement.Anti-skid bumps 117 on the outer wall of the storage tank 116 can increase the friction to prevent the user's hands from slipping.

[0036] Embodiment two: according to Figure 1 、 Figure 2 、 Figure 3 、 Figure 6 and Figure 7 As shown, the filtering mechanism 1 comprises a first valve body 101, the top of the first valve body 101 is provided with a first shaft hole 102, the inner surface wall of the first shaft hole 102 movably inserts a valve rod 103, the bottom of the valve rod 103 is fixedly installed with a positioning block 104, the inner surface wall of the first valve body 101 movably inserts two fixed rings 105, the outer wall of the two fixed rings 105 is fixedly installed with a first spring 106 on one side, the outer wall of the two first springs 106 is fixedly installed with a sealing ring 107 on one side, the outer surface wall of the two sealing rings 107 is in contact with a valve ball 108, the liquid leakage monitoring mechanism 2 comprises a collecting cylinder 201, the bottom of the collecting cylinder 201 is fixedly communicated with a one-way valve 202, the outer surface wall of the collecting cylinder 201 is provided with an alarm 203, the inner surface wall of the collecting cylinder 201 is provided with a group of water grooves 204, the inner surface wall of the collecting cylinder 201 is fixedly installed with a group of electromagnets 205, the inner surface wall of the collecting cylinder 201 movably inserts a piston 206, the bottom of the piston 206 is fixedly installed with a group of permanent magnets 207, the bottom of the piston 206 is provided with a first electrode 208, the inner wall bottom of the collecting cylinder 201 is provided with a second electrode 209, the bottom of the piston 206 is fixedly installed with a second spring 210, and the bottom of the second spring 210 is fixedly connected with the inner wall bottom of the collecting cylinder 201, the bottom of the first valve body 101 is fixedly communicated with the top of the collecting cylinder 201.

[0037] In this embodiment, when the ball valve leaks due to failure of the sealing element or damage to the ball, the leaked water first flows through the sealing ring 107 to the bottom of the valve ball 108, and then the flowing liquid enters the inside of the collection cylinder 201 under the action of gravity and reaches the top of the piston 206. The leaked water can pass through the water groove 204 on the inner wall of the collection cylinder 201, pass through the piston 206, and reach the bottom of the collection cylinder 201, so that the second electrode 209 at the bottom is immersed in water. With the passage of time, the liquid level in the collection cylinder 201 rises continuously, and when the first electrode 208 at the bottom of the piston 206 also contacts the water, the current can pass through the water as a conductor. Through the first electrode 208 to the second electrode 209, the circuit forms a path, at which time the alarm 203 will quickly sound an alarm to remind people to repair or replace the leaking valve body in time. At the same time, the electromagnet 205 also generates a magnetic pole with the same name as the permanent magnet 207 below it under the action of the current. Since the same name magnetic poles repel each other, the permanent magnet 207 starts to descend and drives the piston 206 at the top to squeeze the second spring 210 to move synchronously. When the piston 206 descends, the pressure below it increases continuously, and the one-way valve 202 opens under the action of pressure to timely drain the internal water. After the internal water in the collection cylinder 201 is drained, the lack of conductor between the first electrode 208 and the second electrode 209 causes the circuit to be disconnected, and the permanent magnet 207 will generate an attractive force to the electromagnet 205 that has lost its magnetic force. At this time, the second spring 210 that is squeezed starts to stretch, and under the action of these two forces, the piston 206 starts to rise against the air pressure. When the piston 206 reaches the water groove 204, the water flow can continue to flow below the piston 206, so that the air pressure above and below the piston 206 remains the same. Since the distance between the first electrode 208 and the second electrode 209 is relatively short, the air pressure difference below the piston 206 after the water is drained will not be too large, and the permanent magnet 207 and the second spring 210 are sufficient to push the piston 206 up. This mechanism can monitor the sealing performance of the ball valve in real time, timely detect potential leakage problems, and sound an alarm. After the alarm, the accumulated water can be drained in time, so that the leaked water cannot enter the subsequent pipeline, which helps to prevent safety accidents caused by leakage and also allows the equipment to be reused, improving the practicality of the equipment.

[0038] Embodiment Three: According to Figure 1 、 Figure 2 、 Figure 3 、 Figure 6 、 Figure 7 、 Figure 8 and Figure 9As shown, the drive mechanism 3 comprises a protective cover 301, a group of third shaft holes 302 are opened at the top of the protective cover 301, a movable hole 303 is opened at one side of the outer wall of the protective cover 301, a second rotating shaft 304 is movably inserted between the inner wall of the group of third shaft holes 302, a worm gear 305 is fixedly sleeved on the outer wall of the second rotating shaft 304, a motor 306 is fixedly installed on one side of the inner wall of the protective cover 301, a worm 307 is fixedly installed on the output end of the motor 306, and the outer wall of the worm 307 is in meshing connection with the inner wall of the worm gear 305, a toothed shaft 308 is fixedly installed on one side of the outer wall of the worm 307, a toothed cylinder 309 is movably sleeved on the outer wall of the toothed shaft 308, a third spring 310 is fixedly installed on one side of the outer wall of the toothed cylinder 309, and one side of the outer wall of the third spring 310 is in contact with one side of the inner wall of the protective cover 301, a connecting rod 311 is fixedly installed on one side of the outer wall of the toothed cylinder 309, and the inner wall of the movable hole 303 is movably inserted with the outer wall of the connecting rod 311, a rotating wheel 312 is fixedly installed on one side of the outer wall of the connecting rod 311, the bottom of the first valve body 101 is fixedly communicated with the top of the collecting cylinder 201, the top of the first valve body 101 is fixedly connected with the bottom of the protective cover 301, and the top of the valve rod 103 is fixedly connected with the bottom of the second rotating shaft 304.

[0039] In this embodiment, when the ball valve needs to be started, the motor 306 can be started, at this time the motor 306 drives the worm 307 to start rotating, the worm 307 drives the worm gear 305 connected therewith to rotate synchronously, the worm 307 and the worm gear 305 constitute a self-locking structure, which can effectively prevent the valve ball 108 below from being opened or closed accidentally, thereby avoiding possible safety accidents, when the worm gear 305 rotates, the second rotating shaft 304 inside rotates synchronously, and the valve rod 103 below starts to move, the opening and closing of the ball valve are controlled by controlling the valve ball 108, when the motor 306 is damaged or cannot be used due to power failure, the user can pull the connecting rod 311 outward by rotating the rotating wheel 312, when the connecting rod 311 moves, the toothed cylinder 309 fixedly installed on one side of the outer wall of the connecting rod 311 moves and squeezes the third spring 310, at this time the gear on the inner wall of the toothed cylinder 309 meshes with the gear on the outer wall of the toothed shaft 308, driving the toothed cylinder 309 and the toothed shaft 308 to form a linkage mechanism, the user only needs to rotate the rotating wheel 312, and the toothed cylinder 309 and the toothed shaft 308 can be driven to rotate synchronously through the connecting rod 311, at this time the worm 307 drives the worm gear 305, the second rotating shaft 304 and the valve rod 103 to rotate again, and the opening and closing of the ball valve are controlled, this manual control function avoids the risk of equipment shutdown caused by the failure of the electric actuator, provides additional protection for the stable operation of the equipment, and ensures that the production process is not affected.

[0040] The working principle of the whole mechanism is as follows: during the starting process of the ball valve, people can choose to activate the motor 306, once the motor 306 starts, it will drive the worm 307 to start rotating, because the worm 307 is meshed with the worm gear 305, so the worm gear 305 will also rotate with it, with the rotation of the worm gear 305, it will drive the second rotating shaft 304 inside to rotate synchronously, the rotating motion of the second rotating shaft 304 drives the valve stem 103 below to move, and the valve ball 108 on the valve stem 103 is used to accurately control the opening and closing state of the ball valve, when the motor 306 is damaged due to failure or cannot work normally due to power failure, users can still control the ball valve by manual operation, the specific operation method is: by rotating the wheel 312 to pull the connecting rod 311 outward, with the movement of the connecting rod 311, the toothed cylinder 309 firmly installed on one side of the outer wall will also move, in this process, the third spring 310 will be moderately compressed, when the toothed cylinder 309 moves into place, the rack on the inner surface wall will accurately mesh with the rack on the outer surface wall of the toothed shaft 308, this meshing action makes the toothed cylinder 309 and the toothed shaft 308 form an efficient linkage mechanism, then the user only needs to rotate the rotating wheel 312 slightly, through the transmission of the connecting rod 311, the toothed cylinder 309 and the toothed shaft 308 will rotate synchronously, this rotating action will further drive the worm 307, the worm 307 drives the worm gear 305 and the second rotating shaft 304 to rotate, finally the valve stem 103 rotates, thereby realizing the opening or closing control of the ball valve, when the valve stem 103 rotates in the first shaft hole 102, the positioning block 104 below will rotate together, the positioning block 104 in turn drives the valve ball 108 to rotate, thereby changing the shape of the channel inside the first valve body 101, realizing the opening or closing function of the valve, the sealing ring 107 on both sides of the valve ball 108 closely adheres to the valve ball 108, when the temperature, pressure and flow of the pipeline change, or the sealing ring 107 is seriously worn due to long-term use, a gap may appear between the sealing ring 107 and the valve ball 108, resulting in a decrease in the sealing performance of the valve, at this time, the first spring 106 that is compressed will stretch and push the sealing ring 107 to closely adhere to the valve ball 108, thereby restoring and maintaining the sealing performance of the valve, if the sealing ring 107 or the first spring 106 is damaged and cannot continue to work, the user can easily disassemble the valve from the pipeline, by rotating the second valve body 109, it can be taken out from the inside of the first valve body 101, then rotate the valve stem 103, so that the positioning block 104 remains horizontal with the first valve body 101, at this time the valve ball 108 inside the first valve body 101 can roll out, making it convenient for the user to replace the two sealing rings 107 and related parts, the disassembly process is convenient and fast, reducing the maintenance cost and time, when the valve is in use, the water flow will first contact the first filter screen 110, which can effectively filter impurities in the water, preventing impurities from blocking or corroding the pipeline and equipment behind, at the same time, the water flow will drive the rotating paddle 113 to rotate, driving the first rotating shaft 112 to rotate in the second shaft hole 111,The cleaning brush 114 is further rotated to brush off the impurities accumulated on the surface of the first filter screen 110. During this process, the baffle 115 also moves with the cleaning brush 114, exposing the blocked feed inlet 119. Under the action of centrifugal force, the impurities are brought into the storage tank 116. The two arc-shaped second filter screens 118 inside the storage tank 116 form a narrow passage, preventing the leakage of impurities from the inside of the storage tank 116. When the valve is closed, the rotating paddle 113 stops due to the lack of water flow. At this time, the baffle 115 resets the cleaning brush 114 with the first rotating shaft 112, so that the feed inlet 119 at the top of the storage tank 116 is always blocked by a baffle 115, further preventing leakage of impurities. By collecting and storing the impurities generated during the filtering process, the first filter screen 110 and the pipeline in front of it can be effectively prevented from being blocked. When the accumulated impurities in the storage tank 116 reach a certain level, the user can easily remove and replace the storage tank 116 by simply rotating it from below the second valve body 109. In addition, the outer surface of the storage tank 116 is designed with anti-slip protrusions 117, which can significantly increase the friction between the user's hand and the storage tank 116, effectively preventing the user's hand from slipping when replacing the storage tank 116. When the ball valve encounters leakage due to seal failure or damage to the ball, the leaking water first penetrates the sealing ring 107 and flows to the bottom of the valve ball 108. Subsequently, these water flows enter the collection cylinder 201 under the guidance of gravity and accumulate in the upper area of the piston 206. The specially designed water groove 204 on the inner wall of the collection cylinder 201 allows the leakage water to pass through the piston 206 and eventually collect at the bottom of the collection cylinder 201, causing the second electrode 209 at the bottom to be completely immersed in water. Over time, the water level in the collection cylinder 201 continues to rise, and when the first electrode 208 at the bottom of the piston 206 also contacts the water, a conductive path is formed: the current flows from the first electrode 208 to the second electrode 209 through the water as a conductor. The formation of this circuit path immediately triggers the alarm 203, prompting the operator to repair or replace the leaking valve. At the same time, the electromagnet 205 generates a magnetic pole with the same name as the permanent magnet 207 below it under the action of the current. Due to the principle of repulsion between like poles, the permanent magnet 207 begins to descend, bringing the piston 206 and the second spring 210 at the top with it. As the piston 206 descends, the pressure below the collection cylinder 201 gradually increases, reaching a level sufficient to open the one-way valve 202, thereby timely draining the accumulated water inside. When the accumulated water in the collection cylinder 201 is completely drained, the electrical circuit between the first electrode 208 and the second electrode 209 is broken due to the loss of water conductivity. At this time, the permanent magnet 207 begins to attract the electromagnet 205 that has lost current excitation. At the same time, the previously compressed second spring 210 begins to recover its original length, generating an upward thrust. Under the joint action of these two forces, the piston 206 begins to move upward against the air pressure,When the piston 206 rises to the position of the water tank 204, if the leakage occurs again, the water flow will continue to flow through the water tank 204 to the lower part of the piston 206, so that the air pressure above and below the piston 206 will be balanced, avoiding the difficulty of the movement of the piston 206 caused by the excessive air pressure difference. Since the distance between the first electrode 208 and the second electrode 209 is relatively short, even if there is a certain air pressure change below the piston 206 after the water is drained, the resultant force of the permanent magnet 207 and the second spring 210 is sufficient to push the piston 206 to rise smoothly.
