Description

Technical Field

[0001] This application relates to the field of self-cleaning and self-control valve technology, and in particular to a self-cleaning and self-control valve. Background Technology

[0002] Automatic control valves are key devices in industrial fluid control systems that regulate the flow state of fluids (such as liquids, gases, and steam). Their core function is to precisely control parameters such as fluid flow rate, pressure, flow direction, and liquid level by automatically or manually changing the on / off state of the valve's internal channels and the size of the flow cross-section.

[0003] Butterfly valves, a common type of automatic control valve, have a valve plate on their inner wall. The opening and closing of the valve plate controls the flow of fluid in the pipeline and regulates its flow rate. However, during operation, impurities such as mud, particles, and fibers can enter the valve body along with the fluid in the pipeline and stagnate at the edge of the valve plate. If these impurities prevent the valve plate from closing tightly with the valve body, it can cause fluid leakage, control failure, and other problems, thus affecting the normal operation of the system. Summary of the Invention

[0004] The technical problem this application aims to solve is that when a butterfly valve is in operation, debris will enter the valve body along with the fluid in the pipeline and stagnate at the edge of the valve plate. If the debris prevents the valve plate from closing tightly with the valve body, it will cause problems such as fluid leakage and control failure, thereby affecting the normal operation of the system.

[0005] To address the aforementioned issues, this application provides a self-cleaning and self-controlling valve, comprising a main body assembly including a valve body with a valve plate disposed thereon; A cleaning component, located on one side of a valve plate, includes a support member. The support member includes a fixing ring fixed to one end of the valve plate, and a support ring sleeved on the outside of the fixing ring. The support ring is connected to the rotating shaft of the fixing ring. A motor is installed on the inner wall of the fixing ring. A rotating rod is fixed to one end of the motor. One end of the rotating rod is fixed to one end of the support ring. A slider is installed on the inner wall of the rotating rod. A slide rail is sleeved on the outside of the slider. One end of the slide rail is fixed to one side of the valve plate. A positioning groove, a guide groove, and a sliding groove are formed on the inner wall of the slide rail. Both ends of the guide groove are connected to the positioning groove and the sliding groove.

[0006] The self-cleaning and self-regulating valve provided in this application, through the inclusion of a cleaning component, can perform real-time cleaning of the sealing surface between the valve plate and the valve seat during the valve plate's rotation. This effectively removes accumulated impurities at the joint surface, preventing them from adversely affecting the valve's closure and sealing performance. This further prevents fluid leakage and valve control failure caused by foreign object obstruction, providing dynamic technical support for the long-term stable, safe, reliable, and precise control of the system. Ultimately, this maximizes the overall operational efficiency of the equipment, extends its service life, and reduces maintenance costs.

[0007] To address the support issue, as one option for the aforementioned support, the cleaning assembly also includes a cleaning component. This cleaning component includes a fixing block fixed to one end of the slider. The effect of this solution is that the movement of the fixing block can drive the movement of subsequent components. If the fixing block is missing, the subsequent components will lack support.

[0008] To address the support issue, as one option for the aforementioned connection, a support shaft is inserted into the inner wall of the fixing block, and a cleaning rod is sleeved on the outer side of the support shaft. The advantages of this solution are: the side of the cleaning rod that contacts the valve plate is elastic, which can prevent scratching the valve plate and provide a cushioning effect. The cleaning rod is the main working component, and it is through the installation of the cleaning rod that the surface of the valve plate can be cleaned.

[0009] To address the support issue, as one option for the aforementioned support, a torsion spring is fitted around the outside of the support shaft. One end of the torsion spring is fixed to one end of the cleaning rod, and the other end is fixed to one end of the fixing block. The effect of this solution is that the rotational force of the torsion spring will drive the cleaning rod to move and clean the valve plate.

[0010] To address the cleaning issue, as one option for the aforementioned support, a groove is provided on the inner wall of the support shaft, and a retaining strip is provided on one side of the support shaft. The effect of this solution is that the groove and retaining strip prevent the cleaning rod from lifting up when cleaning the valve plate. Without the groove and retaining strip, the cleaning rod cannot completely adhere to the valve plate, resulting in a weakened cleaning effect.

[0011] To address the support issue, as an alternative to the aforementioned cleaning method, a support frame is fitted around the outer side of the clip. One end of the support frame is fixed to one end of the fixing block. A first spring is fitted around the outer side of the clip, with one end fixed to the surface of the clip and the other end fixed to one end of the support frame. The effect of this solution is that the support frame supports the clip, and the first spring supports the clip, making the clip and the slot more securely engaged.

[0012] To address the support issue, as one option for the aforementioned support, the cleaning assembly also includes a clamping component. The clamping component includes a positioning block fixed to one end of the clamping strip. The inner wall of the positioning block has an inclined groove, and a squeezing column is provided on one side of the inclined groove. The effect of this solution is that by moving the fixed block, a series of components are linked together. Finally, the squeezing action of the inclined groove on the squeezing column causes the positioning block to move and drive the clamping strip to be firmly engaged with the clamping groove, thereby stably fixing the cleaning rod to the outside of the rotating rod and ensuring the structural stability of the cleaning assembly during operation.

[0013] To address the support issue, as one option, a connecting rod is fixed to one end of the extrusion column. A fixing frame is fitted around the outside of the connecting rod, with one end of the fixing frame fixed to the inner wall of the rotating rod. The advantages of this solution are: the fixing frame secures the installation position of the connecting rod, providing stable support for the extrusion column; simultaneously, it allows the extrusion column to move the connecting rod directionally within the fixing frame, ensuring both the structural stability of the extrusion column when subjected to the inclined groove and precise control over its movement.

[0014] To address the protection issue, as one option for the aforementioned support, a protective block is fixed to one end of the connecting rod. The effect of this solution is to prevent the connecting rod from detaching during movement.

[0015] To address the protection issue, as an improvement to the aforementioned support system, a second spring is fixed to one end of the protective block. One end of the second spring is fixed to one end of the protective block, and the other end is fixed to the inner wall of the fixed frame. The effect of this solution is that the second spring provides support to the protective block.

[0016] The technical effect of this application is that during the valve plate rotation operation phase, the sealing interface between the valve plate and the valve seat is cleaned in real time, which can remove the impact of impurity accumulation on the sealing performance, prevent fluid leakage and control failure caused by foreign object jamming, provide dynamic technical support for the long-term, safe and accurate operation of the system, and maximize the overall operating efficiency of the maintenance equipment.

[0025] The embodiments of the technical solution of this application will now be described in detail with reference to the accompanying drawings. These embodiments are only used to more clearly illustrate the technical solution of this application and are therefore merely examples, and should not be used to limit the scope of protection of this application.

[0026] Example 1 Reference Figures 1-7 This is the first embodiment of the present invention. This embodiment provides a self-cleaning self-control valve, which includes a main body component 1 and a cleaning component 2. The two components work together to clean the valve plate.

[0027] The main component 1 includes a valve body 11, on which a valve plate 12 is provided.

[0028] The valve body 11 typically refers to the main structural part of the valve, with pipe ports on both sides for connecting to external pipes to achieve basic functions such as controlling, opening, or cutting off the fluid passage. The valve plate 12 is the opening and closing component of the valve body 11. By rotating around its axis, it changes its relative position to the valve body 11, thereby controlling the flow of fluid in the pipe, the flow rate, or adjusting the direction of medium flow. This is existing technology, and this solution will not elaborate further. Moreover, those skilled in the art can clearly understand the working principle.

[0029] Cleaning component 2, located on one side of valve plate 12, includes a support member 21. The support member 21 includes a fixing ring 211 fixed to one end of valve plate 12. A support ring 212 is sleeved on the outside of the fixing ring 211. The support ring 212 is connected to the fixing ring 211 by a rotating shaft. A motor 213 is provided on the inner wall of the fixing ring 211. A rotating rod 214 is fixed to one end of the motor 213. One end of the rotating rod 214 is fixed to one end of the support ring 212. A slider 215 is provided on the inner wall of the rotating rod 214. A slide rail 216 is sleeved on the outside of the slider 215. One end of the slide rail 216 is fixed to one side of valve plate 12. A positioning groove 216-1, a guide groove 216-2, and a sliding groove 216-3 are provided on the inner wall of the slide rail 216. Both ends of the guide groove 216-2 are connected to the positioning groove 216-1 and the sliding groove 216-3. Except for the fixing ring 211, support ring 212, motor 213 and rotating rod 214, the other components of cleaning component 2 are all in two sets, which are set at both ends of the inner wall of rotating rod 214. Motor 213 is waterproof. Fixing ring 211 is also used to support motor 213. The power supply line of motor 213 is connected to the control end along the rotation axis of valve plate 12.

[0030] The positioning groove 216-1 is used to position the slider 215 and keep it in a vertical position. The guide groove 216-2 is used to guide the slider 215 to move and clean the surface of the valve plate 12. The slide groove 216-3 keeps the slider 215 in the direction of movement. The slide groove 216-3 can keep the slider 215 in an extended state and prevent it from retracting. There are two sliders 215, both of which slide on the inner wall of the rotating rod 214.

[0031] The fixed ring 211, which supports the valve plate 12 and the rotating rod 214, allows the rotating rod 214 to rotate via the power of the motor 213 when the surface of the valve plate 12 needs cleaning. The rotation of the rotating rod 214 causes the support ring 212 to rotate outside the fixed ring 211. This rotation of the rotating rod 214 then rotates the sliders 215 at both ends. The sliders 215 are initially positioned within the positioning groove 216-1. The rotation of the rotating rod 214 causes the sliders 215 to move out of the positioning groove 216-1. 16-1, At this time, the slider 215 enters the inner wall of the guide groove 216-2. The guide groove 216-2 is an inclined surface. The slider 215 can be moved by the guide of the guide groove 216-2. The movement of the slider 215 will cause the cleaning rods 223 at both ends to extend and clean the valve plate 12. At this time, the rotating rod 214 continues to rotate, driving the slider 215 into the inner wall of the slide groove 216-3. At this time, the slider 215 will drive the cleaning rods 223 to maintain the cleaning action, thereby cleaning the surface of the valve plate 12.

[0032] Example 2 Reference Figures 1-7This is the second embodiment of the present invention, which is based on the previous embodiment.

[0033] Specifically, the cleaning component 2 also includes a cleaning element 22, which includes a fixing block 221 fixed to one end of the slider 215.

[0034] There are two fixed blocks 221, both of which are fixed to one end of the slider 215. The movement of the slider 215 will cause the fixed blocks 221 to move.

[0035] Specifically, a support shaft 222 is inserted into the inner wall of the fixing block 221, and a cleaning rod 223 is sleeved on the outer side of the support shaft 222.

[0036] The side of the cleaning rod 223 that contacts the valve plate 12 is elastic, which can prevent scratching the valve plate 12 and provide a cushioning effect.

[0037] The support shaft 222 is used to support the cleaning rod 223. The support shaft 222 is movably connected to the fixing block 221. The movement of the fixing block 221 will drive the support shaft 222 to move, and the movement of the support shaft 222 will drive the cleaning rod 223 to extend.

[0038] Specifically, a torsion spring 224 is sleeved on the outside of the support shaft 222. One end of the torsion spring 224 is fixed to one end of the cleaning rod 223, and the other end is fixed to one end of the fixing block 221.

[0039] After the cleaning rod 223 is moved to the extended position, it will be released by the torsion spring 224. The rebound force will drive the support shaft 222 to rotate, and the support shaft 222 will drive the cleaning rod 223 to rotate to the surface of the valve plate 12 for cleaning.

[0040] Specifically, a slot 222-1 is provided on the inner wall of the support shaft 222, and a retaining strip 225 is provided on one side of the support shaft 222.

[0041] After the cleaning rod 223 is moved to the extended position, the torsion spring 224 will be released. The rebound force will drive the support shaft 222 to rotate. The rotation of the support shaft 222 will drive the slot 222-1 to rotate. After the slot 222-1 rotates to the edge of the locking strip 225, the locking strip 225 will engage with the slot 222-1, thereby preventing the cleaning rod 223 from lifting.

[0042] Example 3 Reference Figure 6 and Figure 7 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0043] Specifically, a support frame 226 is fitted on the outside of the clip 225. One end of the support frame 226 is fixed to one end of the fixing block 221. A first spring 227 is fitted on the outside of the clip 225. One end of the first spring 227 is fixed to the surface of the clip 225, and the other end is fixed to one end of the support frame 226.

[0044] The support frame 226 is used to support the clip 225 and is movably connected to it. The support shaft 222 rotates to drive the slot 222-1 to rotate. After the slot 222-1 rotates to the edge of the clip 225, the force of the first spring 227 will cause the clip 225 to engage with the slot 222-1, thereby preventing the cleaning rod 223 from lifting and thus limiting the cleaning rod 223.

[0045] Specifically, the cleaning component 2 also includes a clamping member 23, which includes a positioning block 231 fixed to one end of the clamping strip 225. The inner wall of the positioning block 231 is provided with a groove 231-1, and a squeezing post 232 is provided on one side of the groove 231-1.

[0046] The movement of the fixed block 221 causes the support shaft 222 to move, which in turn causes the cleaning rod 223 to move. The movement of the fixed block 221 causes the locking strip 225 to move, which in turn causes the positioning block 231 to move. The positioning block 231 causes the inclined groove 231-1 to move. The cleaning rod 223 moves to the outside of the rotating rod 214. At this time, the inclined groove 231-1 will squeeze the extrusion column 232. The setting of the extrusion column 232 can make the positioning block 231 move. The movement of the positioning block 231 causes the locking strip 225 to be firmly engaged with the groove 222-1.

[0047] When the slider 215 moves into the guide groove 216-2, it will cause the cleaning rod 223 to retract. One end of the cleaning rod 223 will contact the rotating rod 214. The inclined groove 231-1 on the positioning block 231 will release the locking strip 225 from the locking groove 222-1 through the squeezing column 232. When the guide groove 216-2 enters the positioning groove 216-1, the cleaning rod 223 will move to the inner wall of the rotating rod 214. The rotation of the cleaning rod 223 will drive the support shaft 222 to rotate. The rotation of the support shaft 222 will apply a torsional force to the torsion spring 224. At this time, the locking groove 222-1 will also separate from the locking strip 225, thereby resetting the rotating rod 214. The return of the rotating rod 214 to its original position will cause the cleaning rod 223 to return to its original position.

[0048] Specifically, a connecting rod 233 is fixed to one end of the extrusion column 232, and a fixing frame 234 is sleeved on the outside of the connecting rod 233. One end of the fixing frame 234 is fixed to the inner wall of the rotating rod 214.

[0049] The connecting rod 233 is used to support the extrusion column 232. The movement of the extrusion column 232 can drive the connecting rod 233 to move within the fixed frame 234.

[0050] Specifically, a protective block 235 is fixed to one end of the connecting rod 233.

[0051] The protective block 235 is used to support the connecting rod 233 and prevent the connecting rod 233 from falling off when it moves. The movement of the connecting rod 233 will drive the protective block 235 to move.

[0052] Specifically, a second spring 236 is fixed to one end of the protective block 235. One end of the second spring 236 is fixed to one end of the protective block 235, and the other end is fixed to the inner wall of the fixing frame 234.

[0053] The second spring 236 is used to support the protective block 235.

[0054] The protective block 235 moves to compress the second spring 236. The compression post 232 allows the positioning block 231 to drive the locking strip 225 to firmly engage with the slot 222-1. When the cleaning rod 223 returns to its original position, the positioning block 231 moves again, and one end of it will compress the compression post 232. This time, the guide of the inclined groove 231-1 will drive the positioning block 231 to move. The movement of the positioning block 231 will cause the locking strip 225 to relax with the slot 222-1. At this time, the cleaning rod 223 retracts. The movement of the cleaning rod 223 and its contact with the rotating rod 214 will cause the cleaning rod 223 to rotate. The rotation of the cleaning rod 223 will drive the support shaft 222 to rotate and apply a torsional force to the torsion spring 224. At this time, the slot 222-1 will also separate from the locking strip 225, thereby resetting the rotating rod 214. The return of the rotating rod 214 to its original position will cause the cleaning rod 223 to return to its original position.

[0055] In use, when cleaning the surface of the valve plate 12 is required, the motor 213 drives the rotating rod 214 to rotate. The rotation of the rotating rod 214 causes the support ring 212 to rotate outside the fixed ring 211. The rotation of the rotating rod 214 causes the sliders 215 at both ends to rotate. The sliders 215 are initially in the positioning groove 216-1. The rotation of the rotating rod 214 causes the sliders 215 to move out of the positioning groove 216-1. At this time, the sliders 215 enter the inner wall of the guide groove 216-2. The guide groove 216-2 guides the sliders 215 to move. The movement of the sliders 215 causes the fixed block 221 to move inward. The movement of the fixed block 221 causes the support shaft 222 to move, which in turn moves the cleaning rod 223 to the outside of the extended rotating rod 214. Once the cleaning rod 223 is extended, the torsion spring 224 is released. The force of the torsion spring 224's rotation drives the support shaft 222 to rotate, which in turn rotates the cleaning rod 223 to clean the surface of the valve plate 12. After the cleaning rod 223 extends, the slider 215 enters the slide groove 216-3. The cleaning rod 223 allows for automatic cleaning of the valve plate 12 surface without manual disassembly, saving labor costs. This reduces cost and assembly / disassembly time, and effectively removes impurities from the valve plate surface. The rotation of the support shaft 222 drives the slot 222-1 to rotate. After the slot 222-1 rotates to the edge of the retaining strip 225, the force of the first spring 227's rebound will cause the retaining strip 225 to engage with the slot 222-1, thus preventing the cleaning rod 223 from lifting. At this time, the slider 215 slides into the slide groove 216-3, keeping the cleaning rod 223 in a cleaning action. The movement of the fixed block 221 drives the retaining strip 225 to move, which in turn drives the positioning block 231 to move. The positioning block 231 then drives the inclined groove 231-1... When the squeezing column 232 engages with the inclined groove 231-1, the positioning block 231 continues to move. The squeezing column 232 squeezes the inclined groove 231-1, causing the positioning block 231 to move. The movement of the squeezing column 232 drives the connecting rod 233 to move. The movement of the connecting rod 233 drives the protective block 235 to move within the fixed frame 234. The movement of the protective block 235 squeezes the second spring 236. The setting of the squeezing column 232 can make the positioning block 231 drive the locking strip 225 to be firmly engaged with the locking groove 222-1. This saves labor and time costs, ensures the cleaning effect through a stable engaging structure, and reduces equipment wear.

[0056] When slider 215 re-enters guide groove 216-2, it will cause cleaning rod 223 to retract. During the movement of cleaning rod 223, one end of it contacts rotating rod 214. At this time, the inclined groove 231-1 on positioning block 231 will cause locking strip 225 and locking groove 222-1 to enter a relaxed state. Simultaneously, the movement of cleaning rod 223 will cause positioning block 231 to press against pressing column 232, further causing locking strip 225 to separate from locking groove 222-1. After cleaning rod 223 contacts rotating rod 214, it rotates, applying torsional force to torsion spring 224 through support shaft 222. At this time, locking groove 222-1 and locking strip 225 are completely separated, rotating rod 214 is reset, and cleaning rod 223 also returns to its initial position. This process can effectively remove impurities from the surface of valve plate 12 in a timely manner, avoid wear caused by impurity accumulation, and reduce equipment failures caused by untimely cleaning.

[0057] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
