Description

Technical Field

[0001] The present invention relates to the technical field of valves, and particularly to a high-pressure pneumatic valve. Background Art

[0002] A high-pressure pneumatic valve is a type of valve. It is a device used to control the flow of liquids or gases. It uses pneumatic power to operate the opening and closing of the valve. Compared with traditional manually operated valves, high-pressure pneumatic valves have higher working pressures and automated control capabilities.

[0003] The patent with the application number CN201922187425.9 discloses a pneumatic-hydraulic high-pressure valve, including a valve body. A sealing cover is fixedly installed at the top of the valve body. An internally threaded cylinder is rotatably connected to the top of the sealing cover through a bearing. A screw rod is threadedly connected to the inner wall of the internally threaded cylinder. A rotating handle is fixedly connected to the top of the internally threaded cylinder. A through hole for the screw rod to pass through is formed on the surface of the rotating handle. A plug for blocking the valve body is fixedly connected to the bottom end of the screw rod. The side of the screw rod near its bottom end is slidably connected to the inner wall of the valve body through a sliding component. Through the cooperation of the above structures, the device can open and close the valve body simply and quickly, and at the same time can adjust the flow rate of the valve body, and can tightly seal the connection between the valve body and the pipeline, improving the airtightness of the connection of the valve body, making the high-pressure valve not easy to leak, avoiding accidents, and improving the safety of valve use. However, when the oil fluid flows through this device, impurities in the oil fluid are likely to accumulate in the valve body, which will cause the blockage of the valve body over time. Therefore, it is necessary to design a high-pressure pneumatic valve with impurity filtration. Summary of the Invention

[0004] The purpose of the present invention is to provide a high-pressure pneumatic valve to solve the problems raised in the above background art.

[0005] To solve the above technical problems, the present invention provides the following technical solution: a high-pressure pneumatic valve, comprising a valve body, a left pipeline and a right pipeline, and further comprising a filtering device, an adjusting device, a protection device and a collecting device; the filtering device includes a baffle plate, a moving plate, a base, a transmission rod, a sealing plate, a threaded rod and a filter plate, the baffle plate is fixedly connected to the inner wall of the valve body, the moving plate is slidably connected to the inner wall of the valve body, the base is threadedly connected to the inner wall of the valve body, the threaded rod is fixedly connected to the bottom of the moving plate, the transmission rod is rotatably connected to the bottom end of the threaded rod, the sealing plate is fixedly connected to the inner wall of the bottom end of the transmission rod, and the filter plate is fixedly connected to the inner wall of the right pipeline; the adjusting device is arranged inside the valve body, the protection device is arranged inside the adjusting device, and the collecting device is arranged inside the base; the surface of the left pipeline is fixedly connected to the inner wall of the valve body, the surface of the right pipeline is fixedly connected to the inner wall of the valve body, both sides of the sealing plate are respectively in contact with the right end of the left pipeline and the left end of the right pipeline, the surface of the sealing plate is slidably connected to the inner wall of the baffle plate, and a spring is arranged between the top of the moving plate and the inner wall of the valve body. When high-pressure gas enters the valve body, the gas will push the moving plate upward. The moving plate will move upward and compress the spring. At the same time, the moving plate will drive the sealing plate upward through the threaded rod and the transmission rod. The sealing plate will move out of the left pipeline and the right pipeline, so that the left pipeline and the right pipeline are communicated. At this time, the oil can flow through the left pipeline and the right pipeline, and the oil will pass through the filter plate in the right pipeline, so that the impurities in the oil are blocked by the filter plate, preventing the impurities in the oil from moving to the next process together with the oil, thus affecting the normal operation of the subsequent process. When the air pressure decreases, the spring will drive the moving plate to move downward and reset. The moving plate will drive the sealing plate to move downward. The sealing plate will push the impurities accumulated on the left side of the filter plate downward, so that the impurities fall into the base, preventing the impurities from accumulating on the filter plate and causing blockage of the filter plate. After that, the base can be taken out and the internal impurities can be cleaned, which is very convenient and fast.

[0006] According to the above technical solution, the adjusting device includes a rotating rod, a partition plate, a sealing ring, a limiting rod and a vibration device. The rotating rod is rotatably connected to the inner wall of the top of the valve body. The partition plate is threadedly connected to the surface of the threaded rod. The sealing ring is fixedly connected to the inner wall of the partition plate. The limiting rod is fixedly connected to the bottom of the partition plate. The vibration device is arranged on the surface of the limiting rod. The vibration device includes an impeller and a convex rod. The impeller is rotatably connected to the surface of the limiting rod. The convex rod is fixedly connected to the right side of the filter plate. The surface of the limiting rod is slidably connected to the inner wall of the baffle plate. The surface of the limiting rod is slidably connected to the inner wall of the right pipeline. The surfaces of the partition plate and the sealing ring are slidably connected to the inner wall of the valve body. The bottom end of the rotating rod is fixedly connected to the top end of the threaded rod. The surface of the rotating rod is in contact with the inner wall of the moving plate. By rotating the rotating rod with a tool, the rotating rod will drive the threaded rod to rotate. The threaded rod will drive the partition plate to rotate through the thread. However, the partition plate is limited by the limiting rod and cannot rotate. Therefore, the threaded rod can only drive the partition plate to move up and down through the thread, and then the space between the moving plate and the partition plate can be changed, so that the amount of air required to open the valve can be changed, and then the threshold value of the introduced gas can be changed, which can be adjusted at any time according to different working environments, and the scope of application is improved. When the partition plate moves up and down, it will drive the limiting rod to move. The limiting rod will drive the impeller to move. When the oil fluid flows, the impeller will be pushed by the oil fluid to rotate. The rotation of the impeller will collide with the convex rod, and the convex rod will drive the filter plate to vibrate. Vibration can make the impurities on the surface of the filter plate more compact, and then more impurities can be filtered out. At the same time, the limiting rod drives the impeller to move, which can change the knocking point of the impeller on the convex rod, make the vibration of the filter plate more uniform, and make the distribution of impurities more uniform.

[0007] According to the above technical solution, the protection device includes a transmission plate, an elastic rubber, a through hole and a stirring device. The transmission plate is fixedly communicated with the inner wall of the top of the partition plate. The elastic rubber is fixedly connected to the inner wall of the top of the partition plate. The through hole is opened on the surface of the transmission plate. The stirring device is arranged at the bottom of the elastic rubber. The stirring device includes a sleeve, a screw rod and a stirring plate. The sleeve is fixedly connected to the bottom of the elastic rubber. The screw rod is movably connected to the inner wall of the sleeve. The stirring plate is fixedly connected to the surface of the screw rod. A spiral groove is opened on the surface of the screw rod. A clamping block is arranged on the inner wall of the sleeve and is located in the spiral groove. The surface of the transmission plate is in contact with the inner wall of the valve body. When gas enters the valve body, the gas pressure will not only push the moving plate upward, but also push the elastic rubber to bulge into the partition plate. After the elastic rubber bulges, it will compress the space inside the partition plate, so that the lubricating oil inside the partition plate is squeezed into the transmission plate and seeps out through the small through holes on the transmission plate. The seeping oil will be distributed on the transmission plate. When gas enters the valve body, there will be more or less some dust. The existence of dust will cause the gap between the sealing ring and the partition plate to increase, affecting the sealing effect. When the partition plate drives the transmission plate to move upward, the dust on the inner wall of the valve body can be scraped off, so that the dust falls on the transmission plate and contacts the lubricating oil on the transmission plate, making the dust adhere to the oil, preventing the dust from contacting the sealing ring, and at the same time preventing the scraped dust from flying again. At the same time, when the elastic rubber arches downward, it will drive the sleeve to move downward. The downward movement of the sleeve will drive the spiral groove on the surface of the screw rod to move through the clamping block on the inner wall. Since the sleeve is limited by the elastic rubber and cannot rotate, the downward movement of the sleeve will drive the screw rod to rotate through the guide on the surface of the spiral groove. The screw rod will drive the stirring plate to rotate, and the stirring plate will stir the oil inside the partition plate to prevent the fluidity of the oil from becoming poor due to temperature reasons, thereby affecting its seepage effect from the small through holes.

[0008] According to the above technical solution, the collection device includes a moving rod, a pressing plate and a rotating plate. The moving rod is fixedly connected to the bottom of the sealing plate. The pressing plate is fixedly connected to the bottom of the moving rod. The rotating plate is rotatably connected to the inner wall of the base through a torsion spring. The surface of the pressing plate is in contact with the upper surface of the rotating plate. The number of the rotating plates is two, and the two rotating plates are symmetrically distributed on the inner wall of the base. When the sealing plate moves downward and resets, it will drive the moving rod to move downward. The moving rod will drive the pressing plate to move downward. The pressing plate will contact the rotating plate on the base and push the two rotating plates to open, so that the impurities scraped off by the sealing plate fall between the two opened rotating plates. When the sealing plate moves upward again and opens the left pipeline and the right pipeline, the rotating plate is no longer pushed by the pressing plate. Therefore, the rotating plate will reset and close under the action of the torsion spring to prevent the impurities in the base from being driven to flow when the oil flows.

[0009] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0010] The present invention cooperates with the valve body, the left pipeline, the threaded rod, the baffle plate, the movable plate, the base, the transmission rod, the sealing plate, the right pipeline and the filter plate to operate together. When the high-pressure gas enters the valve body, the gas will push the movable plate to move up, and the movable plate will move up and compress the spring. At the same time, the movable plate will drive the sealing plate through the threaded rod and the transmission rod. The sealing plate will move out of the left pipeline and the right pipeline, so that the left pipeline and the right pipeline are connected. At this time, the oil can flow from the left pipeline and the right pipeline, and the oil will pass through the filter plate in the right pipeline, so that impurities in the oil are blocked by the filter plate. When the air pressure decreases, the spring will drive the movable plate to move down and reset, and the movable plate will drive the sealing plate to move down. The sealing plate will push the impurities accumulated on the left side of the filter plate to move down, so that the impurities fall into the base, so as to prevent the impurities from accumulating on the filter plate and causing the filter plate to be blocked. After that, the base can be taken out and the impurities inside can be cleaned, which is very convenient and quick.

[0011] The present invention cooperates with the rotating rod, the threaded rod, the partition, the sealing ring, the limiting rod, the impeller and the convex rod. When the rotating rod is rotated by a tool, the rotating rod drives the threaded rod to rotate, and the threaded rod drives the partition to rotate through the thread. The partition is limited by the limiting rod and cannot rotate. Therefore, the threaded rod can only drive the partition to move up and down through the thread, thereby changing the space between the movable plate and the partition, thereby changing the amount of air required to open the valve, and further changing the threshold for introducing gas. The tool can be adjusted at any time according to different working environments, thereby improving the scope of application.

[0012] The present invention cooperates with the transmission plate, elastic rubber, sleeve, screw rod, stirring plate and through hole. When gas enters the valve body, the gas pressure will not only push the movable plate upward, but also push the elastic rubber to bulge toward the inside of the partition. After the elastic rubber bulges, it will compress the space inside the partition, so that the lubricating oil inside the partition is squeezed into the transmission plate and seeps out through the tiny through holes on the transmission plate. The seeped oil will be distributed on the transmission plate. When the gas enters the valve body, there will be more or less dust. The presence of dust will cause the gap between the sealing ring and the partition to increase, affecting the sealing effect.

[0013] The present invention cooperates with the moving rod, the pressure plate and the rotating plate to move the moving rod downward when the sealing plate moves downward to reset, and the moving rod drives the pressure plate downward, the pressure plate contacts the rotating plate on the base and pushes the two rotating plates to open, so that impurities scraped off by the sealing plate fall between the two opened rotating plates; when the sealing plate moves upward again and opens the left pipe and the right pipe, the rotating plate is no longer pushed by the pressure plate, so the rotating plate is reset and closed under the action of the torsion spring to prevent the impurities in the base from flowing when the oil flows.

At the same time, the moving plate 7 will drive the sealing plate 10 upward through the threaded rod 32 and the transmission rod 9. The sealing plate 10 will move out of the left pipeline 2 and the right pipeline 11, so that the left pipeline 2 and the right pipeline 11 are communicated. At this time, the oil can flow through the left pipeline 2 and the right pipeline 11, and the oil will pass through the filter plate 12 in the right pipeline 11, so that the impurities in the oil are blocked by the filter plate 12, preventing the impurities in the oil from moving to the next process together with the oil, thereby affecting the normal operation of the subsequent process.

[0027] The adjusting device 3 includes a rotating rod 31, a partition plate 33, a sealing ring 34, a limiting rod 35 and a vibration device.

The vibration device includes an impeller 351 and a convex rod 352. The impeller 351 is rotatably connected to the surface of the limiting rod 35. The convex rod 352 is fixedly connected to the right side of the filter plate 12. The surface of the limiting rod 35 is slidably connected to the inner wall of the baffle 6. The surface of the limiting rod 35 is slidably connected to the inner wall of the right pipeline 11.

The bottom end of the rotating rod 31 is fixedly connected to the top end of the threaded rod 32. The surface of the rotating rod 31 is in contact with the inner wall of the moving plate 7. By rotating the rotating rod 31 with a tool, the rotating rod 31 will drive the threaded rod 32 to rotate. The threaded rod 32 will drive the partition plate 33 to rotate through the thread. However, the partition plate 33 is limited by the limiting rod 35 and cannot rotate. Therefore, the threaded rod 32 can only drive the partition plate 33 to move up and down through the thread, thereby changing the space between the moving plate 7 and the partition plate 33, and then changing the amount of air required to open the valve, and further changing the threshold value of the introduced gas, which can be adjusted at any time according to different working environments, and the scope of application is improved;

[0028] Working principle: When high-pressure gas enters the valve body 1, the gas will push the moving plate 7 upward. The moving plate 7 will move upward and compress the spring. At the same time, the moving plate 7 will drive the sealing plate 10 upward through the threaded rod 32 and the transmission rod 9. The sealing plate 10 will move out of the left pipeline 2 and the right pipeline 11, so that the left pipeline 2 and the right pipeline 11 are communicated. At this time, the oil can flow through the left pipeline 2 and the right pipeline 11. The oil will pass through the filter plate 12 in the right pipeline 11, so that the impurities in the oil are blocked by the filter plate 12, preventing the impurities in the oil from moving to the next process together with the oil, and then affecting the normal operation of the subsequent process. When the air pressure decreases, the spring will drive the moving plate 7 to move downward and reset. The moving plate 7 will drive the sealing plate 10 to move downward. The sealing plate 10 will push the impurities accumulated on the left side of the filter plate 12 downward, so that the impurities fall into the base 8, preventing the impurities from accumulating on the filter plate 12 and causing blockage of the filter plate 12. After that, the base 8 can be taken out and the internal impurities can be cleaned, which is very convenient and fast.

[0029] Rotate the rotating rod 31 through the tool, the rotating rod 31 will drive the threaded rod 32 to rotate, the threaded rod 32 will drive the partition plate 33 to rotate through the thread, and the partition plate 33 is limited by the limiting rod 35 and cannot rotate. Therefore, the threaded rod 32 can only drive the partition plate 33 to move up and down through the thread, thereby changing the space between the moving plate 7 and the partition plate 33, and thus changing the amount of air required to open the valve, and further changing the threshold value of the introduced gas. It can be adjusted at any time according to different working environments, and the scope of application is improved. When the partition plate 33 moves up and down, it will drive the limiting rod 35 to move, the limiting rod 35 will drive the impeller 351 to move, and the impeller 351 will be pushed by the oil when the oil flows through to rotate.

[0030] Embodiment 2

[0031] Please refer to Figures 6-8 , based on Embodiment 1, in this embodiment, the protection device 4 includes a transmission plate 41, an elastic rubber 42, a through hole 43 and a stirring device. The transmission plate 41 is fixedly communicated with the inner wall of the top of the partition plate 33, the elastic rubber 42 is fixedly connected to the inner wall of the top of the partition plate 33, the through hole 43 is opened on the surface of the transmission plate 41, and the stirring device is arranged at the bottom of the elastic rubber 42; the stirring device includes a sleeve 421, a spiral rod 422 and a stirring plate 423. The sleeve 421 is fixedly connected to the bottom of the elastic rubber 42, the spiral rod 422 is movably connected to the inner wall of the sleeve 421, and the stirring plate 423 is fixedly connected to the surface of the spiral rod 422; a spiral groove is opened on the surface of the spiral rod 422, and a clamping block is arranged on the inner wall of the sleeve 421 and is located in the spiral groove. The surface of the transmission plate 41 is in contact with the inner wall of the valve body 1. When gas enters the valve body 1, the gas pressure will not only push the moving plate 7 upward, but also push the elastic rubber 42 to bulge into the partition plate 33. After the elastic rubber 42 bulges, it will compress the space inside the partition plate 33, so that the lubricating oil inside the partition plate 33 is squeezed into the transmission plate 41 and seeps out through the small through holes 43 on the transmission plate 41. The seeping oil will be distributed on the transmission plate 41. When gas enters the valve body 1, there will be more or less some dust, and the presence of dust will cause the gap between the sealing ring 34 and the partition plate 33 to increase, affecting the sealing effect.

[0032] The collecting device 5 includes a moving rod 51, a pressing plate 52 and a rotating plate 53. The moving rod 51 is fixedly connected to the bottom of the sealing plate 10. The pressing plate 52 is fixedly connected to the bottom of the moving rod 51. The rotating plate 53 is rotatably connected to the inner wall of the base 8 through a torsion spring. The surface of the pressing plate 52 is in contact with the upper surface of the rotating plate 53. The number of the rotating plates 53 is set to two, and the two rotating plates 53 are symmetrically distributed on the inner wall of the base 8. When the sealing plate 10 moves downward and resets, it will drive the moving rod 51 to move downward. The moving rod 51 will drive the pressing plate 52 to move downward. The pressing plate 52 will contact the rotating plate 53 on the base 8 and push the two rotating plates 53 to open, so that the impurities scraped off by the sealing plate 10 fall between the two opened rotating plates 53. When the sealing plate 10 moves upward again and opens the left pipeline 2 and the right pipeline 11, the rotating plate 53 is no longer pushed by the pressing plate 52. Therefore, the rotating plate 53 will reset and close under the action of the torsion spring to prevent the impurities in the base 8 from being driven to flow when the oil fluid flows.

[0033] Working principle: When the gas enters the valve body 1, the gas pressure will not only push the moving plate 7 upward, but also push the elastic rubber 42 to bulge into the inside of the partition plate 33. After the elastic rubber 42 bulges, it will compress the space inside the partition plate 33, so that the lubricating oil inside the partition plate 33 is squeezed into the transmission plate 41 and oozes out through the small through holes 43 on the transmission plate 41. The oozed oil fluid will be distributed on the transmission plate 41. When the gas enters the valve body 1, there will be more or less some dust. The existence of the dust will cause the gap between the sealing ring 34 and the partition plate 33 to increase, affecting the sealing effect. When the partition plate 33 drives the transmission plate 41 to move upward, it can scrape the dust on the inner wall of the valve body 1, so that the dust falls on the transmission plate 41 and contacts the lubricating oil on the transmission plate 41, making the dust adhere to the oil fluid, preventing the dust from contacting the sealing ring 34, and at the same time preventing the scraped dust from flying again. At the same time, when the elastic rubber 42 arches downward, it will drive the sleeve 421 to move downward. The downward movement of the sleeve 421 will drive the movement of the spiral groove on the surface of the screw rod 422 through the inner wall block. Since the sleeve 421 is limited by the elastic rubber 42 and cannot rotate, the downward movement of the sleeve 421 will drive the screw rod 422 to rotate through the guide on the surface of the spiral groove. The screw rod 422 will drive the stirring plate 423 to rotate, and the stirring plate 423 will stir the oil fluid inside the partition plate 33 to prevent the fluidity of the oil fluid from becoming poor due to temperature reasons, thereby affecting its oozing effect from the small through holes 43.

[0034] When the sealing plate 10 moves downward and resets, it will drive the moving rod 51 to move downward. The moving rod 51 will drive the pressing plate 52 to move downward. The pressing plate 52 will contact the rotating plate 53 on the base 8 and push the two rotating plates 53 to open, so that the impurities scraped off by the sealing plate 10 will fall between the two opened rotating plates 53. When the sealing plate 10 moves upward again and opens the left pipeline 2 and the right pipeline 11, the rotating plate 53 is no longer pushed by the pressing plate 52. Therefore, the rotating plate 53 will reset and close under the action of the torsion spring, preventing the impurities in the base 8 from being driven to flow when the oil fluid flows.
