Description
Technical Field
[0001] The present invention relates to the technical field of flat gate valves, in particular to a protective device for a valve stem of a flat gate valve. Background Art
[0002] At present, condensation appears on the flat gate valve of the oil pipeline from the valve stem stuffing box to the valve stem nut. A large amount of condensation will accumulate over a long period of time. In low temperature conditions, ice will freeze the valve stem, making it impossible for the valve to open and close normally, causing equipment failure and inability to operate normally. Long-term accumulation of condensation will also cause corrosion to the valve body and stuffing box. Currently, in the coal chemical industry and open-pit oil production industries, there are connecting valves on the transmission pipelines. Due to production needs, some valves are placed in the open air for a long time. During production, no protective measures are taken. The valve stem is directly exposed to the outside, the valve stem lacks protection, the valve stem thread is covered with sand and dust, or is corroded by rain, dew, frost and snow. In this environment, it will rust over time, making it difficult to open and close the valve, and in severe cases, it may even get stuck and unable to open.
[0003] At present, after a long period of use, the valve stem itself is easily affected by external factors, thereby affecting the service life of the valve stem. Therefore, a new design has been made to address this situation. Summary of the Invention
[0004] To achieve the above objectives, the present invention is implemented through the following technical solutions: A protective device for a flat gate valve stem, comprising a composite mechanism, a processing mechanism fixedly connected to the interior of the composite mechanism, and a cleaning mechanism fixedly connected to one side of the exterior of the composite mechanism;
[0005] The composite mechanism includes a composite shell, an external shell is fixedly connected to the side of the composite shell away from the cleaning mechanism, a slide rail is fixedly connected to the top of the external shell, a sliding block is slidably connected to the inner side of the slide rail, and a motor is fixedly connected to the top of the sliding block. The composite shell is arranged on the outer side of the valve stem to cover the valve stem, and the sliding block slides on the inner side of the slide rail, so that the sliding block drives the polishing column to move from the external shell to the composite shell, and the polishing column is driven by the motor to rotate, so that the polishing column rubs the surface of the valve stem, thereby polishing the surface of the valve stem. On the one hand, rust on the surface of the valve stem is removed. After long-term use, the valve stem is exposed to wind, sun and water, which can easily cause the surface of the valve stem to rust. On the other hand, if the surface of the valve stem is not rusted, the surface of the valve stem can be polished. The impurities or stains are rubbed and peeled off, reducing the corrosion of the valve stem by impurities, thereby extending the service life of the components; the bottom of the sliding block is rotatably connected to a polishing column, and when the motor controls the rotation of the polishing column, it adapts to the lifting and lowering of the valve stem, thereby improving the cleaning range of the valve stem through the rotation of the valve stem; the bottom of the polishing column is rotatably connected to a sliding group, and the sliding group moves as the sliding block slides, thereby maintaining the balance of the polishing column; the bottom of the composite shell is fixedly connected to an anti-obstruction mechanism, and the top of the composite shell is fixedly connected to a protective mechanism; the inner wall of the composite shell is fixedly connected to the outer side of the processing mechanism near the circular groove, and the debris and impurities generated by friction fall into the inside of the composite shell, and the debris is collected and cleaned by the cleaning mechanism to keep the inside of the equipment clean.
[0006] Preferably, the protective mechanism includes an annular block. When the valve stem is lifted or lowered on the inner wall of the composite shell, it comes into friction contact with the inner side of the annular block. The stability of the valve stem during rotation and lifting is improved through friction, and the valve stem is prevented from falling off when it fails. The valve stem is prevented from flying off and safety hazards are reduced. A strip cutout is provided on the inner side of the annular block. By providing the strip cutout and the groove, the friction force on the component is increased, thereby improving the anti-slip effect on the valve stem and further reducing safety hazards. When the valve stem rotates and rubs against the component, the outer side of the annular block is fixedly connected to a connecting column. The outer side of the connecting column is sleeved with a first spring. The first spring is used for shock absorption and buffering, reducing the amplitude of the component and improving the stability of the component during operation, thereby maintaining stable operation of the equipment. The bottom of the connecting column is fixedly connected to the top of the composite shell.
[0007] Preferably, the anti-obstruction mechanism includes an anti-obstruction shell, the inner wall of the anti-obstruction shell is fixedly connected to a ring frame, the inner side of the ring frame is fixedly connected to a ring-shaped block, and during the daily lifting of the valve stem, it is easy to carry water to cover the valve stem and the inside of the components, resulting in water stagnation, thereby causing corrosion and pollution to the components, and the valve stem is easy to rust, thereby affecting the service life of the components. When the valve stem rubs inside the anti-obstruction shell, it rubs against the ring-shaped block. The ring-shaped block is made of fiber material, etc., and has good adsorption properties for water, thereby achieving the effect of blocking water from entering and avoiding water corrosion to the components. A semi-arc incision is provided on the outside of the ring-shaped block. By opening the semi-arc incision and grooving, the deformation range of the components is increased, and the integrity of the components during friction with the valve stem is improved, thereby extending the service life of the components. A drain pipe is fixedly connected to the inclined part of the outer side of the anti-obstruction shell. As the valve stem rubs against the ring-shaped block, water is squeezed out of the ring-shaped block and discharged from the drain pipe.
[0008] Preferably, the processing mechanism includes a trapezoidal shell, and a connecting shaft is fixedly connected between the opposite surfaces of the two trapezoidal shells. A cylindrical block is fixedly connected to the outer side of the connecting shaft. When the valve stem rotates and rises and falls inside the composite shell, the cylindrical block rubs against the surface of the valve stem, thereby increasing the cleaning efficiency of the valve stem and improving the degree of cleaning of the valve stem. When the polishing column rubs against the surface of the valve stem, it also frictionally adapts to the surface of the cylindrical block, and cleans impurities on the surface of the polishing column through the cylindrical block, reducing the adsorption of impurities on the surface of the component, avoiding affecting the subsequent friction effect, and keeping the equipment clean, thereby extending the service life of the component. A buffer mechanism is fixedly connected to the middle of one side of the outer side of the trapezoidal shell.
[0009] Preferably, the buffer mechanism includes a trapezoidal frame, and a second spring is fixedly connected to one side of the outer surface of the trapezoidal frame. When the polishing column slides on the inner side of the slide rail along with the sliding block, the internal shaft block of the polishing column contacts the buffer plate, and the buffer plate is subjected to pressure to squeeze the second spring, thereby playing a shock-absorbing and buffering role. At the same time, the component is supported by the reaction of the spring structure, thereby achieving a braking effect on the component, avoiding excessive sliding of the component, and having a certain protective effect on the component. The buffer plate is fixedly connected to the side of the outer side of the second spring away from the trapezoidal frame.
[0010] Preferably, a silicone block is fixedly connected to the side of the outside of the buffer plate away from the second spring. The silicone block is made of silicone material. The silicone material increases the wear resistance of the components, thereby reducing wear between components and extending the service life of the components. Secondly, the silicone material increases the absorption of impact force, thereby increasing the buffering effect. The buffer plate is fixedly connected to a connecting block at the inclined part close to the trapezoidal frame side. When the buffer plate moves toward the trapezoidal frame, the connecting block moves toward the trapezoidal frame, thereby keeping the components stable. The outer side of the connecting block is slidably connected to the outer side of the trapezoidal frame.
[0011] Preferably, the cleaning mechanism includes a connecting tube, an external bracket fixedly connected to the outside of the connecting tube on a side away from the composite housing, a fan plugged into the inside of the external bracket, and a rotating mechanism fixedly connected to the inner wall of the connecting tube. The fan generates wind to suck debris out of the interior of the composite housing and move it toward the fan. A pipe can be installed outside the external bracket to guide and collect the debris, thereby reducing debris inside the device, keeping the interior of the device clean, and preventing excessive accumulation of impurities that may affect subsequent device operations.
[0012] Preferably, the rotation mechanism includes a fixed bracket, a central axis rotatably connected between the opposing surfaces of two fixed brackets, a diagonal bracket fixedly connected to the outside of the central axis, a connecting block fixedly connected to the inside of the diagonal bracket, a U-shaped plate rotatably connected between the opposing surfaces of the connecting block, a friction column rotatably connected to the inside of the U-shaped plate, a friction mechanism fixedly connected to the inside of the U-shaped plate, and a right-angled paddle fixedly connected to the bottom of the inside of the diagonal bracket. The fan generates wind force to suck debris out of the interior of the composite shell and move it toward the fan. A pipe can be installed on the outside of the external bracket to guide and collect the debris, thereby reducing debris inside the equipment, keeping the interior of the equipment clean, and avoiding excessive accumulation of impurities that affect subsequent equipment operations.
[0013] Preferably, the friction mechanism includes a connecting rod, the outer side of the connecting rod is fixedly connected to a four-corner block, and a cylindrical rod is fixedly connected between the opposite surfaces of the two four-corner blocks. The friction column rotates when rubbing against the inner wall of the pipe, and the friction column rotates to frictionally adapt to the cylindrical rod. The cylindrical rod scratches the surface of the friction column, thereby playing a role in cleaning the components, reducing debris accumulation, avoiding impurities from accumulating on the surface of the components, preventing debris from increasing wear between the components, and avoiding affecting the service life of the components.
[0014] The present invention provides a protective device for a flat gate valve stem, which has the following beneficial effects:
[0015] 1. The protective device for the valve stem of a flat gate valve is designed with a composite mechanism. The composite shell is arranged on the outside of the valve stem to cover the valve stem. The sliding block slides on the inside of the slide rail, so that the sliding block drives the grinding column to move from the external shell to the composite shell. The motor drives the grinding column to rotate, so that the grinding column rubs the surface of the valve stem, thereby grinding the surface of the valve stem. On the one hand, rust on the surface of the valve stem is removed. After long-term use, the valve stem is exposed to wind, sun and water, which easily causes rust on the surface of the valve stem. On the other hand, if the surface of the valve stem is not rusted, impurities or stains on the surface of the valve stem can be rubbed and peeled off, reducing the corrosion of the valve stem by impurities, thereby extending the service life of the component. The sliding group moves as the sliding block slides, thereby maintaining the balance of the grinding column. When the motor controls the rotation of the grinding column, it adapts to the lifting and lowering of the valve stem, thereby increasing the cleaning range of the valve stem through the rotation of the valve stem. Debris and impurities generated by friction fall into the inside of the composite shell, and the debris is collected and cleaned by the cleaning mechanism to keep the inside of the equipment clean.
[0016] 2. The protective equipment for the valve stem of the flat gate valve is designed with an anti-blocking mechanism. During the daily lifting and lowering of the valve stem, it is easy to carry water to cover the inside of the valve stem and components, resulting in water stagnation, which causes corrosion and pollution to the components, and easily causes the valve stem to rust, thereby affecting the service life of the components. When the valve stem rubs inside the anti-blocking shell, it rubs against the ring block. The ring block is made of fiber material, etc., which has good adsorption properties for water, thereby achieving the effect of blocking the entry of water flow and avoiding water flow from corroding the components. By opening a semi-arc incision and grooving to increase the deformation range of the components, the integrity of the components during friction with the valve stem is improved, thereby extending the service life of the components. Secondly, as the valve stem rubs against the ring block, the water flow is squeezed out of the ring block and discharged from the drain pipe.
[0017] 3. The protective device for the valve stem of a flat gate valve is designed with a processing mechanism. When the valve stem rotates and rises inside the composite shell, the cylindrical block rubs against the surface of the valve stem, thereby increasing the cleaning efficiency of the valve stem and improving the degree of cleaning of the valve stem. Secondly, when the polishing column rubs against the surface of the valve stem, it also frictionally adapts with the surface of the cylindrical block, and the cylindrical block cleans impurities on the surface of the polishing column, reducing the adsorption of impurities on the surface of the component, avoiding affecting the subsequent friction effect, and keeping the equipment clean, thereby extending the service life of the component.
[0018] 4. The protective device for the valve stem of a flat gate valve is designed with a buffer mechanism. When the grinding column slides on the inner side of the slide rail along with the sliding block, the internal shaft block of the grinding column contacts the buffer plate. The buffer plate is subjected to pressure to squeeze the second spring, thereby playing a role of shock absorption and buffering. At the same time, the reaction of the spring structure is used to support the components, thereby achieving a braking effect on the components, avoiding excessive sliding of the components, and having a certain protective effect on the components. The silicone block is made of silicone material, and the silicone material increases the wear resistance of the components, thereby reducing the wear between the components and extending the service life of the components. Secondly, the silicone material increases the absorption of impact force, thereby increasing the buffering effect. When the buffer plate moves toward the trapezoidal frame, the connecting block moves toward the trapezoidal frame to keep the components stable.
[0019] 5. The protective device for the valve stem of a flat gate valve is designed with a protective mechanism. When the valve stem rises and falls on the inner wall of the composite shell, it comes into friction contact with the inner side of the annular block. The friction improves the stability of the valve stem during rotation and lifting, avoids the valve stem from falling off when it fails, prevents the valve stem from flying off and reduces safety hazards. By opening strip incisions and grooves, the friction force on the components is increased, thereby improving the anti-slip effect on the valve stem and further reducing safety hazards. When the valve stem rotates and rubs against the components, the first spring is used for shock absorption and buffering, reducing the amplitude of the components and improving the stability of the components during operation, thereby maintaining stable operation of the equipment.

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0032] The first embodiment, as Figures 1 to 5 As shown, the present invention provides a technical solution: a protective device for a flat gate valve stem, comprising a composite mechanism 1, a processing mechanism 2 is fixedly connected to the interior of the composite mechanism 1, and a cleaning mechanism 3 is fixedly connected to one side of the exterior of the composite mechanism 1;
[0033] The composite mechanism 1 includes a composite shell 11, and the side of the outside of the composite shell 11 away from the cleaning mechanism 3 is fixedly connected to an external shell 12, the top of the external shell 12 is fixedly connected to a slide rail 13, the inner side of the slide rail 13 is slidably connected to a sliding block 14, the top of the sliding block 14 is fixedly connected to a motor 15, the bottom of the sliding block 14 is rotatably connected to a polishing column 16, the bottom of the polishing column 16 is rotatably connected to a slide group 17, the bottom of the composite shell 11 is fixedly connected to an anti-obstruction mechanism 19, the top of the composite shell 11 is fixedly connected to a protective mechanism 18, and the inner wall of the composite shell 11 is fixedly connected to the outer side of the processing mechanism 2 near the circular groove. The composite housing 11 is arranged on the outside of the valve stem to cover the valve stem. The sliding block 14 slides on the inside of the slide rail 13, so that the sliding block 14 drives the grinding column 16 to move from the external housing 12 to the composite housing 11. The motor 15 drives the grinding column 16 to rotate, so that the grinding column 16 rubs the surface of the valve stem, thereby grinding the surface of the valve stem. On the one hand, rust on the surface of the valve stem is removed. The valve stem is easily rusted after long-term use, exposure to wind, sun and water, and on the other hand, if the surface of the valve stem is not rusted, impurities or stains on the surface of the valve stem can be rubbed and peeled off, reducing the corrosion of the impurities on the valve stem, thereby extending the service life of the component. The sliding group 17 moves as the sliding block 14 slides, thereby maintaining the balance of the grinding column 16. When the motor 15 controls the rotation of the grinding column 16, it adapts to the lifting and lowering of the valve stem. In this way, the cleaning range of the valve stem is increased through the rotation of the valve stem. Debris and impurities generated by friction fall into the inside of the composite housing 11, and the debris is collected and cleaned by the cleaning mechanism 3 to keep the interior of the equipment clean.
[0034] The protective mechanism 18 includes an annular block 181, with a strip-shaped cutout 184 formed on its inner side. A connecting post 182 is fixedly connected to the outer side of the annular block 181. A first spring 183 is sleeved on the outer side of the connecting post 182. The bottom of the connecting post 182 is fixedly connected to the top of the composite housing 11. When the valve stem is raised or lowered on the inner wall of the composite housing 11, it comes into frictional contact with the inner side of the annular block 181. This friction improves the stability of the valve stem during rotation and raising and lowering, prevents the valve stem from falling off in the event of a valve stem failure, and prevents the valve stem from flying off, thereby reducing safety hazards. The strip-shaped cutout 184 and the grooves increase friction on the components, thereby improving the anti-slip effect on the valve stem and further reducing safety hazards. When the valve stem rotates and rubs against the components, the first spring 183 provides shock absorption and buffering, reducing the amplitude of the components and improving the stability of the components during operation, thereby maintaining stable operation of the equipment.
[0035] The anti-obstruction mechanism 19 includes an anti-obstruction shell 191, the inner wall of the anti-obstruction shell 191 is fixedly connected to a ring frame 192, the inner side of the ring frame 192 is fixedly connected to a ring block 193, the outer side of the ring block 193 is provided with a semi-arc cutout 194, and a drain pipe 195 is fixedly connected to the inclined part of the outer side of the anti-obstruction shell 191. During the daily lifting and lowering of the valve stem, it is easy for water to be carried and covered inside the valve stem and components, resulting in water stagnation, thereby causing corrosion and pollution to the components, and easily causing the valve stem to rust, thereby affecting the service life of the components. When the valve stem rubs inside the anti-blocking shell 191, it rubs against the ring block 193. The ring block 193 is made of fiber material, etc., which has good adsorption properties for water, thereby achieving the effect of blocking the entry of water flow and avoiding water flow from corroding the components. By opening a semi-arc incision 194 and grooving, the deformation range of the component is increased, and the integrity of the component during friction with the valve stem is improved, thereby extending the service life of the component. Secondly, as the valve stem rubs against the ring block 193, the water flow is squeezed out of the ring block 193 and discharged from the drain pipe 195.
[0036] The second embodiment, based on the first embodiment, see Figures 6 and 7 As shown, the processing mechanism 2 includes a trapezoidal shell 21, a connecting shaft 22 is fixedly connected between the opposite surfaces of the two trapezoidal shells 21, a cylindrical block 23 is fixedly connected to the outside of the connecting shaft 22, and a buffer mechanism 24 is fixedly connected to the middle of one side of the outer side of the trapezoidal shell 21. When the valve stem rotates and rises and falls inside the composite shell 11, the cylindrical block 23 rubs against the surface of the valve stem, thereby increasing the cleaning efficiency of the valve stem and improving the degree of cleaning of the valve stem. Secondly, when the polishing column 16 rubs against the surface of the valve stem, it also frictionally adapts to the surface of the cylindrical block 23, and the cylindrical block 23 cleans impurities on the surface of the polishing column 16, reducing the adsorption of impurities on the surface of the component, avoiding affecting the subsequent friction effect, and keeping the equipment clean, thereby extending the service life of the component.
[0037] The buffer mechanism 24 includes a trapezoidal frame 241, to which a second spring 242 is fixedly connected on one side of the outer portion of the trapezoidal frame 241. A buffer plate 243 is fixedly connected on the outer side of the second spring 242, away from the trapezoidal frame 241. As the polishing column 16 slides along the inner side of the slide rail 13 with the sliding block 14, the internal shaft of the polishing column 16 contacts the buffer plate 243. The buffer plate 243 is subjected to pressure, which compresses the second spring 242, thereby providing a shock-absorbing and buffering effect. Simultaneously, the reaction of the spring structure supports the component, thereby achieving a braking effect on the component, preventing it from sliding excessively and providing a certain degree of protection for the component.
[0038] A silicone block 244 is fixedly connected to the side of the buffer plate 243 away from the second spring 242. A connecting block 245 is fixedly connected to the inclined portion of the buffer plate 243 near the trapezoidal frame 241. The outer side of the connecting block 245 is slidably connected to the outer side of the trapezoidal frame 241. The silicone block 244 is made of silicone. This material increases the wear resistance of the components, thereby reducing wear between components and extending the service life of the components. The silicone material also improves the absorption of impact force, thereby enhancing the cushioning effect. When the buffer plate 243 moves toward the trapezoidal frame 241, the connecting block 245 moves toward the trapezoidal frame 241, thereby maintaining the stability of the components.
[0039] The third embodiment, based on the first and second embodiments, see Figures 8 to 10 As shown, the cleaning mechanism 3 includes a connecting tube 31. An external bracket 32 is fixedly connected to the side of the connecting tube 31 away from the composite housing 11. A fan 33 is plugged into the inside of the external bracket 32. A rotating mechanism 34 is fixedly connected to the inner wall of the connecting tube 31. The fan 33 generates wind force to suck debris out of the interior of the composite housing 11 and move it toward the fan 33. A pipe can be installed outside the external bracket 32 to guide and collect the debris, thereby reducing debris inside the equipment, keeping the interior clean, and preventing excessive accumulation of impurities that may affect subsequent equipment operations.
[0040] The rotating mechanism 34 includes fixed brackets 341. A central shaft 342 is rotatably connected between the opposing surfaces of the two fixed brackets 341. A diagonal bracket 343 is fixedly connected to the outer side of the central shaft 342. A connecting block 344 is fixedly connected to the inner side of the diagonal bracket 343. A U-shaped plate 345 is rotatably connected between the opposing surfaces of the connecting block 344. A friction column 347 is rotatably connected to the inner side of the U-shaped plate 345. A friction mechanism 346 is fixedly connected to the inner side of the U-shaped plate 345. A right-angled paddle 348 is fixedly connected to the bottom of the inner side of the diagonal bracket 343. Wind generated by the fan 33 contacts the right-angled paddle 348, driving the components to rotate, causing the friction column 347 to rub against the inner wall of the pipe, thereby cleaning the inner wall of the pipe and reducing the accumulation of impurities on the inner wall of the pipe, thereby preventing the impact on the airflow within the pipe.
[0041] Friction mechanism 346 includes a connecting rod 3461, with a square block 3462 fixedly connected to its outer side. A cylindrical rod 3463 is fixedly connected between the opposing surfaces of the two square blocks 3462. As friction post 347 rubs against the inner wall of the pipe, it rotates. This rotation creates frictional engagement with cylindrical rod 3463, which scrapes against the surface of friction post 347. This cleans the component, reduces debris accumulation, and prevents impurities from accumulating on the component surface. This prevents debris from increasing wear on the component and shortening its service life.
[0042] When in use, the valve stem is arranged inside the composite shell 11. When the valve stem rotates and rises, it first contacts the inside of the anti-blocking mechanism 19, and the anti-blocking mechanism 19 absorbs and cleans impurities or water stains on the surface of the valve stem, thereby reducing the entry of impurities into the composite shell 11 and reducing the adsorption of impurities on the surface of the valve stem, slowing down the corrosion of the valve stem surface by impurities, thereby extending the service life of the components. The water flow and impurities retained in the anti-blocking mechanism 19 are discharged outward from the drain pipe 195, reducing the accumulation of impurities inside the equipment and keeping the interior clean. During the operation of the valve stem, it is frictionally adapted with the surface of the processing mechanism 2, and the processing mechanism 2 rubs during the process of the valve stem rotating and rising, thereby rubbing the surface of the valve stem, thereby reducing impurities on the surface of the valve stem and reducing the corrosion of the valve stem by impurities, thereby extending the service life of the valve stem. At the same time, the grinding column 16 inside the composite mechanism 1 slides inside the slide rail 13 through the sliding block 14, driving The polishing column 16 moves toward the side of the valve stem, and the motor 15 drives the polishing column 16 to rotate, thereby polishing the surface of the valve stem. On the one hand, it removes rust on the surface of the valve stem. After long-term use, the valve stem is exposed to wind, sun and water, which can easily cause the surface of the valve stem to rust. On the other hand, if the surface of the valve stem is not rusted, the impurities or stains on the surface of the valve stem can be rubbed and peeled off to reduce the corrosion of the impurities on the valve stem, thereby extending the service life of the component. During the rotation of the polishing column 16, it rubs against the columnar block 23 to clean the surface of the polishing column 16, reduce the adsorption of debris on the surface of the component, and prevent the debris from increasing the degree of wear between the components, thereby playing a certain protective effect on the equipment. During the cleaning process, debris and impurities generated are deposited inside the composite shell 11, and the debris inside the composite shell 11 is absorbed and cleaned by the cleaning mechanism 3, thereby reducing the debris trapped inside the composite shell 11 and keeping the inside of the equipment clean.
[0043] Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without making creative efforts should fall within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described and explained in the present invention shall be implemented in accordance with conventional means in the field unless otherwise specified or limited.
