A regulating valve with self-cleaning and anti-blocking structure

Abstract

The present invention discloses a regulating valve with a self-cleaning and anti-blocking structure, and the present invention relates to the technical field of regulating valves. Since it is necessary to filter the liquid passing through to remove impurities therein, a large amount of impurities accumulate on the surface of the filter element during long-term filtering work, resulting in obstruction of the filtering work of the filter element. The regulating valve with a self-cleaning and anti-blocking structure gradually reduces the distance between the arc surface block and the filter cylinder from bottom to top, so that the filtered liquid surges from bottom to top in the flow gap. At the same time, in the process of upward surge, due to the reduction of the flow gap, the liquid impacts outward from the inside of the filter cylinder during the flow process, and the impurities blocking the filter holes are cleaned, thereby ensuring the filtering effect during the liquid flow process, and at the same time avoiding the clogging of the filter element after a long period of filtering work, resulting in the inability to use the regulating valve normally.

[0002] At present, the regulating valve, also known as the control valve, is an important execution unit in industrial process control. It changes the fluid flow rate by receiving the control signal output by the regulating control unit and using power operation. The working principle of the regulating valve is based on the principle of fluid mechanics. It adjusts the fluid flow rate by changing the flow area between the valve core and the valve seat. When the regulating valve receives the control signal, the actuator drives the valve core to move, changing the flow area between the valve core and the valve seat, thereby changing the fluid flow rate;

[0003] In the existing valve, since it is necessary to filter the liquid passing through to remove impurities therein, a large amount of impurities are accumulated on the surface of the filter element during long-term filtering work, resulting in obstruction of the filtering work of the filter element.

At the same time, the bevel plate and the stirring wheel cooperate to evenly distribute the accumulated impurities, and the outer side of the groove cover is evenly opened with filter grooves, and the bottom of the groove cover is fixedly installed with a shaft seat, which consists of a shaft rod and a base, and the top end of the shaft rod is fixedly connected to the bottom of the support plate, and the outer side of the shaft rod is rotatably installed with a stirring wheel, and the stirring wheel is located on the inner side of the groove cover, and the bottom of the base is fixedly connected to a chassis, and the bottom of the chassis is fixedly connected to the bottom of the inner wall of the valve body.

[0012] Preferably, the regulating mechanism comprises a support frame, the bottom of the support frame is fixedly connected to the top of the valve cover, the motor is fixedly mounted on the top of the support frame, and a threaded cylinder is fixedly mounted on the output end of the motor, the inner wall of the threaded cylinder is threadedly connected to a threaded rod, a limiting plate is fixedly mounted on the bottom end of the threaded rod, the inner wall of the limiting plate is slidably adapted to the outer side of the support frame, and a connecting rod is fixedly mounted on the bottom of the limiting plate, the bottom end of the connecting rod passes through the valve cover and extends to its bottom, and the bottom end of the connecting rod is fixedly connected to the top of the valve core mechanism, an inner gasket is fixedly mounted on the bottom of the valve cover, a sealing ring is fixedly mounted on the top of the outer side of the inner gasket, and the outer side of the sealing ring is connected to the valve body The inner wall of the valve body is fitted together, and an outer gasket is fixedly installed on the top of the valve core mechanism. Through the adaptation between the inner gasket ring and the outer gasket ring, when the flow gap between the valve body and the valve core mechanism is fully opened, the outer gasket ring and the inner gasket ring are tightly fitted to prevent the overflowed liquid from overflowing from the connecting rod position, and at the same time, the outer gasket ring presses the sealing ring tightly to make the sealing ring close the gap between the valve body and the valve cover, thereby improving the sealing effect of the regulating valve and avoiding excessive liquid pressure in the pipeline, which leads to liquid overflow. The outer side of the inner gasket ring is an inclined surface and is inclined inwardly from top to bottom, the inner wall of the outer gasket ring is an inclined surface and is inclined inwardly from top to bottom, the outer side of the inner gasket ring is adapted to the inner wall of the outer gasket ring, and the outer gasket ring is slidably adapted to the inner wall of the valve body.

[0013] Preferably, the valve core mechanism comprises a hollow cylinder, the outer side of the hollow cylinder is slidably fitted with the inner wall of the valve body, the top of the hollow cylinder is fixedly connected to the bottom of the outer gasket ring, and the bottom of the hollow cylinder is fixedly connected with a sealing cylinder, an annular groove is provided at the center position of the outer side of the sealing cylinder, and sliding grooves are evenly provided in the annular groove of the sealing cylinder, a rubber ring is fixedly installed at the annular groove of the sealing cylinder, a sliding block is fixedly installed on the inner wall of the rubber ring, the outer side of the sliding block is slidably fitted with the sliding groove of the sealing cylinder, an inclined panel is slidably installed on the inner wall of the hollow cylinder, the inclined panel is evenly installed along the center position of the hollow cylinder, and an inner pressure plate is fixedly installed on the bottom of the inclined panel.

Through the cooperation of the sliding plate and the inclined plate, the liquid pressure in the valve body is too large. When the circulation gap is fully closed, the upwelling liquid impacts the sliding plate, causing the sliding plate to move upward, driving the inclined plate and the inner pressure plate to move outward, and the rubber ring is pressed outward by the sliding block to increase the fitting pressure between the rubber ring and the valve body, so as to avoid excessive liquid flow pressure when the circulation gap is fully closed, resulting in failure to close. The outer side of the sliding plate is an inclined surface, and the opposite surface of the inclined plate is an inclined surface, and the opposite surface of the inclined plate is matched with the outer side of the sliding plate.

[0014] The present invention provides a regulating valve with a self-cleaning and anti-blocking structure. It has the following beneficial effects:

[0015] 1. The regulating valve with a self-cleaning and anti-blocking structure gradually reduces the distance between the arc block and the filter cartridge from bottom to top, so that the filtered liquid surges from bottom to top in the flow gap. At the same time, in the process of upward surge, due to the reduction of the flow gap, the liquid impacts outward from the inside of the filter cartridge during the flow, and the impurities blocking the filter holes are cleaned, thereby ensuring the filtering effect during the liquid flow process, and avoiding the clogging of the filter element after a long period of filtering work, which makes the regulating valve unable to be used normally.

[0016] Second, the regulating valve with a self-cleaning and anti-blocking structure cooperates with the bevel disk and the stirring wheel. The bevel disk is used to block the liquid during the introduction process to prevent the liquid from directly impacting the accumulated impurities, causing the impurities to surge and spread, and increasing the difficulty of the filter cartridge. At the same time, the bevel disk and the stirring wheel cooperate to evenly distribute the accumulated impurities.

[0017] 3. The regulating valve with a self-cleaning and anti-blocking structure, through the adaptation between the inner gasket ring and the outer gasket ring, can prevent the overflowed liquid from overflowing from the connecting rod position through the tight fit between the outer gasket ring and the inner gasket ring when the flow gap between the valve body and the valve core mechanism is fully opened. At the same time, the outer gasket ring presses the sealing ring tightly to make the sealing ring close the gap between the valve body and the valve cover, thereby improving the sealing effect of the regulating valve and avoiding excessive liquid pressure in the pipeline to cause liquid overflow.

[0018] Fourth, the regulating valve with a self-cleaning and anti-blocking structure makes the liquid pressure in the valve body too high through the cooperation of the sliding plate and the inclined plate. When the circulation gap is fully closed, the upwelling liquid impacts the sliding plate, causing the sliding plate to move upward, driving the inclined plate and the inner pressure plate to move outward, and tightening the rubber ring outward through the slider, thereby increasing the fitting pressure between the rubber ring and the valve body, avoiding excessive liquid flow pressure when the circulation gap is fully closed, resulting in failure to close.

[0030] The first embodiment, as Figure 1 to Figure 2 and Figures 7 to 9 As shown, the present invention provides a technical solution: a regulating valve with a self-cleaning and anti-blocking structure, comprising:

[0031] A valve body 1, wherein the valve body 1 has a connecting space inside, and a connecting pipe 7 is symmetrically installed on the outside of the valve body 1, and a valve cover 6 is fixedly installed on the top of the valve body 1;

[0035] A motor 5, which is used to control the valve core mechanism 3 through the regulating mechanism 4, and the motor 5 is installed on the top of the regulating mechanism 4;

[0036] Wherein, the filter mechanism 2 comprises a filter cartridge 23, the top of which is fixedly connected to the inner wall of the valve body 1, and filter holes are evenly arranged on the outer side of the filter cartridge 23, and a curved block 24 is fixedly installed on the bottom of the inner wall of the filter cartridge 23, the outer side of the curved block 24 is a curved surface, and the distance between the curved block 24 and the filter cartridge 23 gradually decreases from bottom to top, and an outer cover ring 21 is fixedly installed on the bottom of the inner wall of the valve body 1, and the outer cover ring 21 is located at the bottom of the outer side of the filter cartridge 23. When the impurities in the liquid are filtered through the filter mechanism 2, the liquid is introduced into the valve body 1 through the connecting pipe 7 on one side, and in the process of introduction, the liquid first impacts the filter cartridge 23, and the impurities in the liquid are filtered out through the filter holes evenly arranged on the outer side of the filter cartridge 23, and the liquid after the impurities are removed enters the filter cartridge 2. 3, and the impurities blocked by the filter cartridge 23 slide down along the outside of the filter cartridge 23, and cooperate with the flowing liquid through the inclined surface of the inclined disk 22, and are introduced into the bottom of the inclined disk 22 through the empty groove on the top of the inclined disk 22. During the flow of liquid inside the valve body 1, the liquid after filtering out impurities surges upward through the gap between the arc block 24 and the filter cartridge 23, and flows to the connecting pipe 7 on the other side through the flow gap opened between the valve core mechanism 3 and the valve body 1. In the process of the liquid surging upward, the filter hole of the filter cartridge 23 is impacted from the inside to the outside through the gradually reduced gap between the arc block 24 and the filter cartridge 23, and the impurities blocking the filter hole are cleaned. The central position of the inner wall of the outer cover ring 21 is fixedly installed with a bevel disk 22, and the bevel disk 22 is inclined downward from the outside to the inside.

[0037] A support plate 25 is fixedly installed at the bottom of the filter cartridge 23, and the outer side of the support plate 25 is fixedly connected to the inner wall of the bevel plate 22. Empty grooves are evenly opened on one side of the top of the bevel plate 22 close to the support plate 25, and a groove cover 26 is fixedly installed at the bottom of the bevel plate 22. The outer side of the groove cover 26 is evenly opened with filter grooves, and an axle seat 28 is fixedly installed at the bottom of the groove cover 26. The axle seat 28 consists of a shaft and a base, and the top of the shaft is fixedly connected to the bottom of the support plate 25. A stirring wheel 29 is rotatably installed on the outer side of the shaft. Impurities falling into the bottom of the bevel plate 22 are driven by the flowing liquid to rotate the stirring wheel 29, and the liquid entering the valve body 1 is driven to rotate and surge, so that the impurities are driven together and evenly distributed at the bottom of the bevel plate 22. The stirring wheel 29 is located on the inner side of the groove cover 26. The bottom of the base is fixedly connected to a chassis 27, and the bottom of the chassis 27 is fixedly connected to the bottom of the inner wall of the valve body 1.

[0038] The second embodiment is based on the first embodiment. Figure 3 to Figure 4As shown, the adjusting mechanism 4 includes a supporting frame 41, the bottom of the supporting frame 41 is fixedly connected to the top of the valve cover 6, the motor 5 is fixedly installed on the top of the supporting frame 41, and a threaded cylinder 42 is fixedly installed on the output end of the motor 5, the inner wall of the threaded cylinder 42 is threadedly connected to a threaded rod 43, and a limiting plate 45 is fixedly installed on the bottom end of the threaded rod 43, and the inner wall of the limiting plate 45 is slidably adapted to the outer side of the supporting frame 41. At the same time, after the liquid passes through the filtering mechanism 2, the threaded cylinder 42 is driven to rotate by the motor 5, and the threaded connection between the threaded cylinder 42 and the threaded rod 43 is utilized. When the threaded rod 43 is restricted by the limiting plate 45, it is driven by the rotating threaded cylinder 42 to move up and down, and the valve core mechanism 3 is driven up and down by the connecting rod 44 to adjust the size of the flow gap between the valve core mechanism 3 and the valve body 1, and a connecting rod 44 is fixedly installed on the bottom of the limiting plate 45, and the bottom end of the connecting rod 44 passes through the valve cover 6 and extends to its bottom, and the bottom end of the connecting rod 44 is fixedly connected to the top of the valve core mechanism 3.

[0039] An inner gasket 46 is fixedly installed at the bottom of the valve cover 6, and a sealing ring 47 is fixedly installed at the top of the outer side of the inner gasket 46. The outer side of the sealing ring 47 fits against the inner wall of the valve body 1, and an outer gasket 48 is fixedly installed at the top of the valve core mechanism 3. The outer side of the inner gasket 46 is an inclined surface and is inclined inwardly from top to bottom, and the inner wall of the outer gasket 48 is an inclined surface and is inclined inwardly from top to bottom. After the gap is fully opened, the outer gasket 48 fits tightly against the inner gasket 46, and at the same time, the inner wall of the outer gasket 48 is adapted to the outer side of the inner gasket 46, so that the top of the outer gasket 48 after the gap is fully opened presses the sealing ring 47 upward, so that the sealing ring 47 is close to the bottom of the valve cover 6, so that the gap between the valve cover 6 and the valve body 1 is completely sealed by the sealing ring 47, the outer side of the inner gasket 46 is adapted to the inner wall of the outer gasket 48, and the outer gasket 48 is slidably adapted to the inner wall of the valve body 1.

[0040] The third embodiment is based on the first and second embodiments. Figures 5 and 6As shown, the valve core mechanism 3 includes a hollow cylinder 31, the outer side of the hollow cylinder 31 is slidably matched with the inner wall of the valve body 1, the top of the hollow cylinder 31 is fixedly connected to the bottom of the outer gasket 48, and the bottom of the hollow cylinder 31 is fixedly connected with a sealing cylinder 34, and an annular groove is provided at the center position of the outer side of the sealing cylinder 34. When the valve core mechanism 3 is driven by the adjusting mechanism 4 to change the position to adjust the size of the flow gap, the flow regulation of the liquid is realized. When the regulating valve is completely closed, the sealing cylinder 34 in the valve core mechanism 3 is tightly fitted with the inner wall of the valve body 1 to completely close the flow gap, and sliding grooves are evenly provided in the annular groove of the sealing cylinder 34, a rubber ring 32 is fixedly installed at the annular groove of the sealing cylinder 34, a slider 35 is fixedly installed on the inner wall of the rubber ring 32, and the outer side of the slider 35 is slidably matched with the sliding groove of the sealing cylinder 34, and an inclined plate 38 is slidably installed on the inner wall of the hollow cylinder 31, and the inclined plate 38 is evenly installed along the center position of the hollow cylinder 31, and The bottom of the inclined plate 38 is fixedly installed with an inner pressure plate 33, and the inner pressure plate 33 corresponds to the slider 35 one by one. The inner wall of the hollow cylinder 31 is fixedly installed with a fixing rod 37, and a sliding plate 36 is slidably installed on the outer side of the fixing rod 37. The outer side of the sliding plate 36 is an inclined surface. During the closing process, the liquid that flows through the filter mechanism 2 passes through the sealing cylinder 34 and enters the interior of the hollow cylinder 31, so that the flowing liquid impacts the sliding plate 36, so that the sliding plate 36 slides upward under the impact force and the restriction of the fixing rod 37. Through the adaptation between the outer side of the sliding plate 36 and the opposite surface of the inclined plate 38, during the upward movement of the sliding plate 36, the inclined plate 38 is pushed outward, and the inner pressure plate 33 is driven to move outward by the inclined plate 38, pushing the slider 35 to press the rubber ring 32, so that the fitting pressure between the outer side of the rubber ring 32 and the valve body 1 is increased, and the opposite surface of the inclined plate 38 is an inclined surface, and the opposite surface of the inclined plate 38 is adapted to the outer side of the sliding plate 36.

[0041] When in use, the pipelines at both ends are connected through the connecting pipe 7, and the liquid in the pipeline enters the interior of the valve body 1 through the connecting pipe 7, and the impurities in the liquid are filtered through the filtering mechanism 2, so that the filtered and impurity-removed liquid passes through the filtering mechanism 2 and flows into the connecting pipe on the other side through the gap opened between the valve core mechanism 3 and the valve body 1, and circulates to the pipeline on the other side. During the conduction process, the regulating mechanism 4 is driven by the motor 5, so that the regulating mechanism 4 drives the valve core mechanism 3 to adjust the position, thereby changing the conductive gap between the valve body 1 and the valve core mechanism 3, and regulating the flowing liquid.

[0042] When the impurities in the liquid are filtered through the filter mechanism 2, the liquid is introduced into the valve body 1 through the connecting pipe 7 on one side. During the introduction process, the liquid first impacts the filter cartridge 23, and the impurities in the liquid are filtered out through the filter holes evenly arranged on the outside of the filter cartridge 23. The liquid after the impurities are removed enters the inside of the filter cartridge 23. At the same time, the impurities blocked by the filter cartridge 23 slide down along the outside of the filter cartridge 23, and cooperate with the flowing liquid through the inclined surface of the inclined disk 22, and are introduced into the bottom of the inclined disk 22 through the empty groove at the top of the inclined disk 22. In the flow of the liquid inside the valve body 1, the liquid after the impurities are filtered out The liquid flows upward through the gap between the arc block 24 and the filter cartridge 23, flows to the connecting pipe 7 on the other side through the flow gap opened between the valve core mechanism 3 and the valve body 1, and in the process of the liquid flowing upward, the filter holes of the filter cartridge 23 are impacted from the inside to the outside through the gradually reduced gap between the arc block 24 and the filter cartridge 23, and the impurities blocking the filter holes are cleaned. At the same time, the impurities that fall into the bottom of the inclined disk 22 are driven by the flowing liquid to rotate the stirring wheel 29, and the liquid entering the valve body 1 is driven to rotate and flow upward, so that the impurities are driven together and evenly distributed at the bottom of the inclined disk 22.

[0043] At the same time, after the liquid passes through the filtering mechanism 2, the motor 5 drives the threaded cylinder 42 to rotate, and utilizes the threaded connection between the threaded cylinder 42 and the threaded rod 43. When the threaded rod 43 is restricted by the limiting plate 45, it is driven by the rotating threaded cylinder 42 to move up and down, and drives the valve core mechanism 3 to move up and down through the connecting rod 44 to adjust the size of the flow gap between the valve core mechanism 3 and the valve body 1. At the same time, after the gap is fully opened, the outer gasket 48 fits tightly with the inner gasket 46, and at the same time, the inner wall of the outer gasket 48 is adapted to the outer side of the inner gasket 46, so that the top of the outer gasket 48 after the gap is fully opened squeezes the sealing ring 47 upward, so that the sealing ring 47 is close to the bottom of the valve cover 6, so that the gap between the valve cover 6 and the valve body 1 is completely sealed by the sealing ring 47.

[0044] When the valve core mechanism 3 is driven by the regulating mechanism 4 to change its position to adjust the size of the flow gap, the flow regulation of the liquid is realized. When the regulating valve is completely closed, the sealing tube 34 in the valve core mechanism 3 fits tightly with the inner wall of the valve body 1 to completely close the flow gap. At the same time, during the closing process, the liquid that flows up through the filtering mechanism 2 passes through the sealing tube 34 and enters the interior of the hollow tube 31, so that the upwelling liquid impacts the sliding plate 36, and the sliding plate 36 slides upward under the restriction of the impact force and the fixing rod 37. Through the adaptation between the outer side of the sliding plate 36 and the opposite surface of the inclined plate 38, during the upward movement of the sliding plate 36, the inclined plate 38 is pushed outward, and the inner pressure plate 33 is driven to move outward by the inclined plate 38, and the sliding block 35 is pushed to press the rubber ring 32, so that the fitting pressure between the outer side of the rubber ring 32 and the valve body 1 is increased.

[0045] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention are implemented according to the conventional means in the field unless otherwise specified and limited.
