Detailed implementation manners
[0027] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.
[0028] The following describes the specific implementation of the present invention in detail with reference to specific embodiments.
[0029] See Figures 1 to 8 , a pneumatically driven vacuum valve device with a support, including: Vacuum valve 10, with tees 101 provided on both side surfaces of the vacuum valve 10, and an exhaust port 102 provided on the top of the vacuum valve 10. A filter screen 120 is detachably connected inside the exhaust port 102; Pressure regulating assembly 2, slidably connected inside the vacuum valve 10. The pressure regulating assembly 2 includes a seal 21, which is slidably connected inside two groups of tees 101. At least six groups of air guide channels 22 and exhaust holes 23 are respectively provided inside and on the surface of the seal 21. The air guide channels 22 and the exhaust holes 23 are respectively in one-to-one communication, and the distance between each group of exhaust holes 23 and the end of the seal 21 increases in an equidistant manner; Noise reduction assembly 3, rotatably connected inside the exhaust port 102. The noise reduction assembly 3 includes a flow dividing wheel 32, which is slidably connected inside the exhaust port 102 and is snap-fitted with the surface of the filter screen 120; Support 1, with at least four groups of card slots 11 provided thereon. Each vacuum valve 10 is detachably inserted into the card slot 11.
[0030] In an embodiment of the present invention, when the vacuum valve 10 is in use, in the normal state, the vacuum valve 10 will be sealed under the action of the pressure regulating assembly 2 to protect the vacuum valve 10 and other equipment. When the air pressure inside the pipeline or equipment is too high or too low, the two sealing members 21 slide spirally in the tee pipe 101 to prevent the sealing members 21 from getting stuck during sliding. And the exhaust holes 23 on the surface of the sealing member 21 will be gradually exposed in sequence for exhausting or admitting air, so that the pressure inside the system can be adjusted step by step to meet different process requirements and prevent equipment damage.
[0031] When the two sealing members 21 approach each other, the lubricating oil in the oil storage tank 41 is discharged through the oil outlet pipe 44 under the extrusion of the piston 43, so that the lubricating oil is evenly distributed on the surface of the sealing member 21. Thus, the vacuum valve 10 can lubricate the sealing member 21 regularly during use, improving the flexibility of the moving parts and reducing the risk of jamming.
[0032] When the oil storage tank 41 slides upward in the exhaust port 102, the rotating shaft 31 will drive the flow dividing wheel 32 to slide upward, so that the flow dividing wheel 32 is separated from the filter net 120, and the air flow is evenly divided into multiple strands after passing through the flow dividing groove 33, reducing the sound energy of a single air flow and achieving the noise reduction effect. As the air pressure inside the pipeline or equipment increases, the gap between the flow dividing wheel 32 and the filter net 120 will gradually increase, thus accelerating the diffusion of the air flow discharged from the filter net 120 and reducing turbulence and noise.
[0033] In an embodiment of the present invention, as Figure 1 and Figure 2 shown, the pressure regulating assembly 2 includes; A fixed column 24, fixed on the inner wall of the tee pipe 101; A spiral groove 25, opened on the surface of the sealing member 21, and the end of the fixed column 24 is slidably connected inside the spiral groove 25; A telescopic member 26, connected between the ends of the two sealing members 21, and a first spring 27 is wound around the surface of the telescopic member 26.
[0034] In this embodiment, when the vacuum valve 10 is in use, the tee pipes 101 on both sides of the vacuum valve 10 are connected to the pipeline or equipment through flanges. In the normal state, the sealing member 21 is located inside the tee pipe 101 under the action of the telescopic member 26 and the first spring 27. At this time, several groups of exhaust holes 23 on the surface of the sealing member 21 are sealed under the action of the inner wall of the tee pipe 101, so as to separate the pipeline or equipment from the external environment or other parts, prevent gas from entering, maintain the vacuum degree, and thus protect the vacuum valve 10 and other equipment.
[0035] When the air pressure inside the pipeline or equipment is too high, at this time, the two sets of seals 21 will slide inward along the inner wall of the three-way pipe 101 under the push of the atmospheric pressure. The two sets of seals 21 will approach each other and compress the telescopic member 26 and the first spring 27. Since the end of the fixed column 24 is slidably connected inside the spiral groove 25, under the action of the fixed column 24 and the spiral groove 25, the seal 21 will rotate inside the three-way pipe 101, so that the seal 21 slides in a spiral manner inside the three-way pipe 101, thereby preventing the seal 21 from getting stuck when sliding inside the three-way pipe 101.
[0036] Since the two sets of seals 21 approach each other, when they slide to a certain position, at this time, the first set of exhaust holes 23 on the surface of the seal 21 will be exposed. Thus, the gas inside the pipeline or equipment will enter the vacuum valve 10 through the first set of air ducts 22 and the exhaust holes 23 and be discharged through the exhaust port 102. When the two sets of seals 21 continue to approach each other, at this time, the second set of exhaust holes 23 on the surface of the seal 21 will be exposed. Thus, the second set of air ducts 22 and the exhaust holes 23 also exhaust air. And so on. As the air pressure inside the pipeline or equipment increases, each set of exhaust holes 23 will be gradually exposed in turn for exhaust, so that the pipeline or equipment can be exhaust in stages, realizing the hierarchical regulation of the pressure inside the pipeline or equipment system.
[0037] When the air pressure inside the pipeline or equipment is too low, contrary to the above operation, at this time, the two sets of seals 21 will move away from each other under the adsorption of the atmospheric pressure. Thus, the exhaust holes 23 on the other end surface of the seal 21 will also be gradually exposed in turn for air intake, so that the pressure inside the system can be adjusted step by step to meet different process requirements and prevent the equipment from being damaged.
[0038] In an embodiment of the present invention, as Figure 4 and Figure 5 shown, the filter net 120 is of an arc structure, and the inner wall of the arc structure of the filter net 120 matches the surface shape of the shunt wheel 32. In this embodiment, the filter net 120 inside the exhaust port 102 can filter the gas entering the vacuum valve 10, preventing impurities or particulate matters in the external environment from entering the inside of the vacuum valve 10 and avoiding damage to the sealing surface. The filter net 120 is arranged in an arc structure, so as to improve the filtering range of impurities and reduce the occurrence of blockage and other situations of the filter net 120.
[0039] Since the inner wall of the arc structure of the filter net 120 matches the surface shape of the shunt wheel 32, in the normal state, the shunt wheel 32 will be snap-fitted to the inner wall of the arc structure of the filter net 120, so that the filter net 120 will not be directly in contact with the external environment, preventing dust in the external environment from adhering to the surface of the filter net 120 and improving the cleanliness of the filter net 120.
[0040] In an embodiment of the present invention, as Figure 6 and Figure 7 shown, the air-driven vacuum valve device with a support further includes a lubrication assembly 4, the lubrication assembly 4 is slidably connected inside the exhaust port 102, and the lubrication assembly 4 includes: An oil storage tank 41, slidably connected to the inner wall of the exhaust port 102, the rotating shaft 31 is rotatably connected between the sides of two groups of oil storage tanks 41, two groups of oil storage tanks 41 are installed, and an oil inlet valve 410 is installed on each of the two groups of oil storage tanks 41, and a check valve is installed inside one end of the oil outlet pipe 44 close to the piston 43; A slide bar 42, penetrating through the filter net 120, one end of the slide bar 42 is fixed to the bottom of the oil storage tank 41, and the other end is slidably connected inside the spiral groove 25, and the depth of the spiral groove 25 on the surface of the seal 21 is set from shallow to deep; A piston 43, slidably connected inside the oil storage tank 41, and the side is connected to the inner wall of the oil storage tank 41 through a second spring 45; An oil outlet pipe 44, one end is fixed to the piston 43, and the other end penetrates through the oil storage tank 41 and the filter net 120 and is located above the spiral groove 25.
[0041] In this embodiment, because the end of the slide bar 42 is slidably connected inside the spiral groove 25, and the depth of the spiral groove 25 on the surface of the seal 21 is set from shallow to deep, so when the two seals 21 approach spirally, the slide bar 42 will gradually slide from the deep part to the shallow part of the spiral groove 25, and then the slide bar 42 will push the oil storage tank 41 to slide upward in the exhaust port 102 under the action of the spiral groove 25. When the oil storage tank 41 slides upward in the exhaust port 102, under the action of the transmission assembly 5, the piston 43 will slide upward on the inner wall of the oil storage tank 41, so that the lubricating oil in the oil storage tank 41 is discharged through the oil outlet pipe 44 under the extrusion of the piston 43. Since one end of the oil outlet pipe 44 is located above the seal 21, the lubricating oil will drip onto the surface of the seal 21. The seal 21 slides spirally inside the three-way pipe 101, so the lubricating oil will be evenly distributed on the surface of the seal 21, so that the vacuum valve 10 can lubricate the seal 21 regularly during use, improving the flexibility of the moving parts and reducing the risk of jamming.
[0042] As Figure 7 shown, an oil inlet valve 410 is installed at the end of the oil storage tank 41, and lubricating oil can be added into the oil storage tank 41 through the oil inlet valve 410, and the lubricating oil is selected as a lubricant that is not easy to volatilize.
[0043] In an embodiment of the present invention, as Figure 4 shown, the noise reduction assembly 3 further includes a rotating shaft 31, the flow dividing wheel 32 is installed on the surface of the rotating shaft 31, and at least two groups of flow dividing grooves 33 are provided on the surface of the flow dividing wheel 32.
[0044] In this embodiment, when the sliding rod 42 pushes the oil storage tank 41 to slide upward in the exhaust port 102 under the action of the spiral groove 25, the two oil storage tanks 41 will drive the flow dividing wheel 32 to slide upward synchronously through the rotating shaft 31, so that the flow dividing wheel 32 is separated from the filter net 120. Therefore, the gas in the vacuum valve 10 can be discharged through the filter net 120, and the air flow passing through the filter net 120 will flow out through the gap between the flow dividing wheel 32 and the exhaust port 102. Since multiple flow dividing grooves 33 are formed on the surface of the flow dividing wheel 32, the air flow is evenly divided into multiple strands after passing through the flow dividing grooves 33, reducing the sound energy of a single-strand air flow and achieving the effect of noise reduction.
[0045] As the internal air pressure of the pipeline or equipment increases, the displacement of the oil storage tank 41 sliding upward in the exhaust port 102 will also increase, and the gap between the flow dividing wheel 32 and the filter net 120 will gradually increase, thereby accelerating the diffusion of the air flow discharged from the filter net 120 and reducing turbulence and noise.
[0046] In an embodiment of the present invention, as Figure 6 and Figure 7 shown, a transmission assembly 5 is installed inside the vacuum valve 10, and the transmission assembly 5 is connected to the piston 43. The transmission assembly 5 includes: A rotating rod 51, rotatably connected inside the oil storage tank 41, with a first gear 52 and a second gear 55 respectively installed at both ends. The first gear 52 is located outside the oil storage tank 41, and the second gear 55 is located inside the oil storage tank 41; A first rack 53, fixed on the inner wall of the exhaust port 102, and meshed with the first gear 52; A second rack 54, connected to the side of the piston 43, and meshed with the second gear 55.
[0047] In this embodiment, when the oil storage tank 41 slides upward in the exhaust port 102, the oil storage tank 41 will drive the first gear 52 and the second gear 55 to slide upward through the rotating rod 51. Since the first gear 52 is meshed with the first rack 53, and the first rack 53 is fixed on the inner wall of the exhaust port 102, the rotating rod 51 will rotate in the oil storage tank 41 under the action of the first gear 52 and the first rack 53. Furthermore, the rotating rod 51 drives the second gear 55 to rotate synchronously. Since the second rack 54 is slidably connected to the inner wall of the oil storage tank 41, the second rack 54 will pull the piston 43 to slide upward in the oil storage tank 41 under the action of the second gear 55, so that the lubricating oil in the oil storage tank 41 will be discharged through the oil outlet pipe 44 under the extrusion of the piston 43, realizing the lubrication of the seal 21 in the vacuum valve 10.
[0048] In an embodiment of the present invention, as Figure 8As shown, the support 1 is circular, and the card slots 11 are evenly distributed in a circular pattern on the support 1. In this embodiment, multiple groups of card slots 11 are provided on the support 1. Therefore, when testing the vacuum valve 10, the testing instrument is placed at the center of the support 1, and multiple vacuum valves 10 are sequentially placed in each card slot 11. After testing a group of vacuum valves 10, only by adjusting the direction of the testing instrument can the next group of vacuum valves 10 be tested, improving the efficiency of batch testing of the vacuum valve 10.
[0049] The working principle of the present invention is as follows: When using the vacuum valve 10, the three-way pipes 101 on both sides of the vacuum valve 10 are connected to the pipeline or equipment through flanges. Under normal conditions, several groups of exhaust holes 23 on the surface of the seal 21 are sealed under the action of the inner wall of the three-way pipe 101, thereby maintaining the vacuum degree and protecting the vacuum valve 10 and other equipment. When the air pressure inside the pipeline or equipment is too high or too low, the two seals 21 approach or move away from each other inside the three-way pipe 101, causing the seal 21 to slide spirally inside the three-way pipe 101, preventing the seal 21 from getting stuck when sliding inside the three-way pipe 101. And the exhaust holes 23 on the surface of the seal 21 will be gradually exposed in sequence for exhaust or intake, so that the pressure inside the system can be adjusted step by step to meet different process requirements and prevent equipment damage.
[0050] When the slide rod 42 pushes the oil storage tank 41 to slide upward in the exhaust port 102 under the action of the spiral groove 25, the two oil storage tanks 41 will drive the diversion wheel 32 to slide upward through the rotating shaft 31, causing the diversion wheel 32 to separate from the filter net 120. The airflow passing through the filter net 120 will flow out through the gap between the diversion wheel 32 and the exhaust port 102. After passing through the diversion groove 33, the airflow is evenly divided into multiple strands, reducing the sound energy of a single strand of airflow and achieving the effect of noise reduction. As the air pressure inside the pipeline or equipment increases, the upward sliding displacement of the oil storage tank 41 also increases, and the gap between the diversion wheel 32 and the filter net 120 gradually increases, thereby accelerating the diffusion of the airflow discharged from the filter net 120 and reducing turbulence and noise.
[0051] In the description of the present invention, it should be noted that unless otherwise clearly specified and limited, the terms "installation", "connection", and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, an electrical connection, or a connection that can communicate with each other; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two components or the interaction relationship between two components.
