Detailed implementation manners

[0032] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, 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.

[0033] The following describes the specific implementation of the present invention in detail with reference to specific embodiments.

[0034] See Figures 1 to 8 , a pneumatically driven vacuum valve device with a support, including:

[0035] A vacuum valve 10, with tee pipes 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;

[0036] A 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 tee pipes 101. At least six groups of air ducts 22 and exhaust holes 23 are respectively provided inside and on the surface of the seal 21. The air ducts 22 and the exhaust holes 23 are respectively connected in one-to-one correspondence, and the distance between each group of exhaust holes 23 and the end of the seal 21 increases in an equidistant manner;

[0037] A noise reduction assembly 3, slidably 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; <(

[0038] A support 1, with at least four groups of card slots 11 provided thereon. Each vacuum valve 10 is respectively detachably inserted into the card slots 11.

[0039] In an embodiment of the present invention, when the vacuum valve 10 is in use, under normal conditions, the vacuum valve 10 will be sealed under the action of the pressure regulating component 2 to protect the vacuum valve 10 and other devices. When the air pressure inside the pipeline or device 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.

[0040] 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 regularly lubricate the sealing member 21 during use, improving the flexibility of the moving parts and reducing the risk of jamming.

[0041] 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 device 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.

[0042] In an embodiment of the present invention, as Figure 1 and Figure 2 shown, the pressure regulating component 2 includes;

[0043] A fixed column 24, fixed on the inner wall of the tee pipe 101;

[0044] A spiral groove 25, formed on the surface of the sealing member 21, and the end of the fixed column 24 is slidably connected inside the spiral groove 25;

[0045] 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.

[0046] 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 device through flanges. Under normal conditions, 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 device from the external environment or other parts, prevent gas from entering, maintain the vacuum degree, and thus protect the vacuum valve 10 and other devices.

[0047] When the air pressure inside the pipeline or equipment is too high, at this time, the two sets of seals 21 will slide inward on the inner wall of the tee 101 under the push of the atmospheric pressure. The two sets of seals 21 will move closer to 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 tee 101, so that the seal 21 will slide in a spiral manner inside the tee 101, thereby preventing the seal 21 from getting stuck when sliding inside the tee 101.

[0048] Since the two sets of seals 21 move closer to 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 move closer to 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 will 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 exhausting air, thereby enabling the pipeline or equipment to exhaust air in stages and realizing the hierarchical regulation of the pressure inside the pipeline or equipment system.

[0049] 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, thereby enabling the pressure inside the system to be adjusted step by step, meeting different process requirements and preventing the equipment from being damaged.

[0050] In an embodiment of the present invention, as Figure 4 and Figure 5 shown, the filter screen 120 is of an arc structure, and the inner wall of the arc structure of the filter screen 120 matches the surface shape of the flow dividing wheel 32. In this embodiment, the filter screen 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 screen 120 is arranged in an arc structure, thereby increasing the filtering range of impurities and reducing the occurrence of blockage and other situations of the filter screen 120.

[0051] Since the inner wall of the arc structure of the filter screen 120 matches the surface shape of the flow dividing wheel 32, in the normal state, the flow dividing wheel 32 will be snap-fitted to the inner wall of the arc structure of the filter screen 120. Thus, the filter screen 120 will not be in direct contact with the external environment, preventing dust in the external environment from adhering to the surface of the filter screen 120 and improving the cleanliness of the filter screen 120.

[0052] In an embodiment of the present invention, as Figure 6 and Figure 7 shown, the pneumatically driven vacuum valve device with a support further includes a lubrication assembly 4, and the lubrication assembly 4 is slidably connected inside the exhaust port 102. The lubrication assembly 4 includes:

[0053] 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. A one-way valve is installed inside one end of the oil outlet pipe 44 close to the piston 43.

[0054] A slide rod 42, penetrating through the filter net 120. One end of the slide rod 42 is fixed to the bottom of the oil storage tank 41, and the other end is slidably connected inside the spiral groove 25. The depth of the spiral groove 25 on the surface of the seal 21 is set from shallow to deep.

[0055] 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.

[0056] An oil outlet pipe 44, one end of which 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.

[0057] In this embodiment, since the end of the slide rod 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, when the two seals 21 approach spirally, the slide rod 42 will gradually slide from the deep part to the shallow part of the spiral groove 25. Furthermore, the slide rod 42 will push the oil storage tank 41 to slide upward inside the exhaust port 102 under the action of the spiral groove 25. When the oil storage tank 41 slides upward inside 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 the 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 tee pipe 101, so the lubricating oil will be evenly distributed on the surface of the seal 21. Thus, 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.

[0058] As Figure 7 shown, an oil inlet valve 410 is installed at the end of the oil storage tank 41. 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.

[0059] In an embodiment of the present invention, as Figure 4As shown, the noise reduction component 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 formed on the surface of the flow dividing wheel 32.

[0060] 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 air flow and achieving the effect of noise reduction.

[0061] 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.

[0062] In an embodiment of the present invention, as Figure 6 and Figure 7 shown, a transmission component 5 is installed inside the vacuum valve 10, the transmission component 5 is connected to the piston 43, and the transmission component 5 includes:

[0063] 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;

[0064] A first rack 53, fixed to the inner wall of the exhaust port 102, and meshed with the first gear 52;

[0065] A second rack 54, connected to the side of the piston 43, and meshed with the second gear 55.

[0066] In this embodiment, when the oil storage tank 41 slides upward in the exhaust port 102, the oil storage tank 41 drives 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 rotates in the oil storage tank 41 under the action of the first gear 52 and the first rack 53. Then, the rotating rod 51 drives the second gear 55 to rotate synchronously. The second rack 54 is slidably connected to the inner wall of the oil storage tank 41, so the second rack 54 pulls the piston 43 to slide upward in the oil storage tank 41 under the action of the second gear 55, causing the lubricating oil in the oil storage tank 41 to 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.

[0067] In one embodiment of the present invention, as Figure 8 shown, the support 1 is circular, and the card slots 11 are circumferentially and equidistantly distributed 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 position 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.

[0068] 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 in the three-way pipe 101, causing the seal 21 to slide in a spiral manner in the three-way pipe 101 to prevent the seal 21 from getting stuck when sliding in 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.

[0069] When the sliding rod 42 pushes the fuel storage tank 41 to slide upward in the exhaust port 102 under the action of the spiral groove 25, the two groups of fuel storage tanks 41 will drive the flow dividing wheel 32 to slide upward through the rotating shaft 31, so that the flow dividing wheel 32 is separated from the filter net 120. 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. After passing through the flow dividing groove 33, the air flow is evenly divided into multiple strands, reducing the sound energy of a single-strand air flow and achieving the effect of noise reduction. As the air pressure inside the pipeline or equipment increases, the displacement of the fuel storage tank 41 sliding upward also increases, and 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.

[0070] 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 can communicate with each other; it can be directly connected or indirectly connected through an intermediate medium, and it can be the internal communication of two components or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0071] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
