Description

Technical Field

[0001] The invention belongs to the field of glasses valves, and in particular relates to a glasses valve with high sealing performance. Background Art

[0002] The glasses valve is a gate valve that shuts off gaseous media manually, electrically, pneumatically, or hydraulically. It features three actuating mechanisms: two manual clamping and releasing mechanisms and an electric mechanism for opening and closing the gate. To open or close the gate, the two manual mechanisms are first released, followed by the electric mechanism. Once the gate is opened or closed, the two manual mechanisms are re-clamped, allowing the pipeline to resume operation. Compared to other valves designed for absolute shutoff in pipelines, the glasses valve boasts a novel structure, light weight, compact size, ease of operation, rapid action, and absolutely reliable gas shutoff performance.

[0003] The existing eye valve with the publication number 201921877490.8 uses the design of an elastic seal to allow the second valve body to slide toward the first valve body, thereby creating a gap between the second valve body and the middle valve body. When in use, the second valve body moves axially away from the middle valve body, creating a gap between the second valve body and the right valve body, thereby avoiding friction between the middle valve body and the second valve body during radial rotation, which can easily lead to damage to the valve body.

[0004] In the above solution, although the use of elastic seals can reduce the friction between the second valve body and the middle valve body and the right valve body, it cannot completely eliminate the friction, and the elastic seals are prone to fatigue damage during long-term use, thereby affecting the sealing effect; on the other hand, the middle valve body is easily contaminated with dust and impurities when it is rotated to the outside of the pipeline, thereby affecting the sealing between the middle valve body and the valve bodies on both sides when it is reconnected to the pipeline.

[0005] In order to avoid the above technical problems, it is necessary to provide a high-sealing glasses valve to overcome the above defects in the prior art. Summary of the Invention

[0006] The object of the present invention is to provide a high-sealing glasses valve, aiming to solve the problem of how to achieve high sealing performance of the glasses valve.

[0007] The present invention is achieved by providing a high-sealing glasses valve, comprising a housing, the housing being fixedly connected to a drive motor, the housing being covered with an end cover, the end cover having the same structure as the housing, and further comprising:

[0008] The output shaft of the driving motor is fixedly connected to the valve plate and the conducting ring. A through hole is provided in the middle of the housing, and the through hole can be communicated with the pipeline. A rotating seat is provided outside the through hole, and the rotating seat is rotatably connected to the housing. A plurality of brushes are provided in an annular manner on the rotating seat. A transmission assembly is provided between the output shaft of the driving motor and the rotating seat, and the transmission assembly is used to drive the rotating seat to rotate;

[0009] A collecting trough is provided on one side of the rotating seat, a filter plate is fixedly connected to the collecting trough, and a material guide trough is provided through the filter plate; an oil tank is provided in the housing, and an oil pipe is connected to the oil tank, and the oil outlet of the oil pipe faces the brush;

[0010] Air bags are provided in an annular manner on both the front and back surfaces of the valve plate and the conducting ring, and a sealing groove is provided between the through hole and the rotating seat.

[0011] According to a further technical solution, the transmission assembly includes a first gear, a second gear, a third gear and a ring gear;

[0012] The number one gear is fixedly connected to the output shaft of the driving motor, the number two gear and the number three gear are both rotatably connected to the inner end surface of the housing, the number two gear is meshed with the number three gear, the number two gear is meshed with the number one gear, the number three gear is meshed with the ring gear, and the ring gear is fixedly connected to the rotating seat.

[0013] According to a further technical solution, the diameter of the first gear is larger than that of the second gear, and the diameter of the second gear is larger than that of the third gear.

[0014] According to a further technical solution, the filter plate is provided with a plurality of arc-shaped scraping openings.

[0015] According to a further technical solution, two filter plates are fixedly connected to the collecting tank, and the arc-shaped scraping openings on the two filter plates are arranged opposite to each other.

[0016] According to a further technical solution, two adjusting screws are provided between the housing and the end cover, and the two adjusting screws and the output shaft of the driving motor are arranged in a triangle.

[0017] According to a further technical solution, a pressure valve is provided at the oil pipe. When the end cover is tightly closed with the shell, the pressure valve is closed under pressure. When the end cover is separated from the shell, the pressure valve opens.

[0018] According to a further technical solution, the airbag is connected to an air pump.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] The present invention provides a high-sealing glasses valve. A driving motor drives a rotating seat to rotate through a transmission assembly. The rotating seat drives a brush to clean the valve plate and the air bags on the front and back sides of the guide ring. An oil pipe sprays lubricating oil onto the brush. When the brush cleans the air bag, dust and impurities are absorbed into the lubricating oil, thereby preventing dust from flying. At the same time, the lubricating oil can also reduce the friction between the brush and the air bag surface. The filter plate scrapes off the dust and impurities on the brush. At this time, the scraped dust and lubricating oil enter the collection tank through the guide trough.

[0021] The present invention provides a high-sealing glasses valve. The conducting ring is sleeved on the outside of the through hole. When the driving motor stops moving and the housing and end cover are closed, the airbags on both sides of the conducting ring enter the sealing grooves on the housing and the end cover, thereby sealing the conducting ring, the housing and the end cover. The lubricating oil on the surface of the airbag can improve the sealing performance.

[0022] The present invention provides a high-sealing glasses valve. When the valve plate and the guide ring are switched in position, the air bags on the front and back sides of the valve plate and the guide ring are first extracted by an air pump, thereby avoiding contact between the air bags and the outer shell and end covers on both sides, increasing the wear on the air bag surface. At the same time, after the air in the air bag is discharged, the contact area between the air bag and the brush can be increased, thereby increasing the cleaning effect of the outer surface of the air bag.

The rotating seat 6 is rotatably connected to the housing 1. A plurality of brushes 7 are provided in an annular manner on the rotating seat 6. A transmission assembly 8 is provided between the output shaft of the drive motor 2 and the rotating seat 6. The transmission assembly 8 is used to drive the rotating seat 6 to rotate;

[0034] A collecting tank 10 is provided on one side of the rotating seat 6, a filter plate 11 is fixedly connected to the collecting tank 10, and a material guide trough 12 is provided through the filter plate 11; an oil tank 13 is provided in the housing 1, and the oil tank 13 is connected to an oil pipe 14, and the oil outlet of the oil pipe 14 faces the brush 7;

[0035] Air bags 15 are provided in an annular shape on both the front and back surfaces of the valve plate 3 and the conducting ring 4 , and a sealing groove 9 is provided between the through hole 5 and the rotating seat 6 .

[0036] Working principle:

[0037] When in use, the end cover is separated from the shell 1, and the driving motor 2 is started. The driving motor 2 drives the valve plate 3 and the conducting ring 4 to rotate at the same time. At this time, the valve plate 3 is separated from the through hole 5, and the conducting ring 4 is close to the through hole 5. The driving motor 2 drives the rotating seat 6 to rotate through the transmission assembly 8. The rotating seat 6 drives the brush 7 to clean the air bags 15 on the front and back sides of the valve plate 3 and the conducting ring 4. The oil pipe 14 sprays lubricating oil on the brush 7. When the brush 7 cleans the air bags 15, dust and impurities are absorbed into the lubricating oil, thereby preventing dust from flying. At the same time, the lubricating oil can also reduce the friction between the brush 7 and the surface of the air bags 15. The filter plate 11 scrapes off the dust and impurities on the brush 7. At this time, the scraped dust and the lubricating oil enter the collecting tank 10 through the guide groove 12.

[0038] Then the conducting ring 4 is sleeved on the outside of the through hole 5, the driving motor 2 stops moving, the outer shell 1 and the end cover are covered, and the airbags 15 on both sides of the conducting ring 4 enter the sealing grooves 9 on the outer shell 1 and the end cover, thereby sealing the conducting ring 4 with the outer shell 1 and the end cover. The lubricating oil on the surface of the airbag 15 can increase the sealing performance.

[0039] In the embodiment of the present invention, Figure 1 As shown, as a preferred embodiment of the present invention, the transmission assembly 8 includes a first gear 81, a second gear 82, a third gear 83 and a ring gear 84; the first gear 81 is fixedly connected to the output shaft of the drive motor 2, the second gear 82 and the third gear 83 are both rotatably connected to the inner end surface of the housing 1, the second gear 82 is meshed with the third gear 83, the second gear 82 is meshed with the first gear 81, the third gear 83 is meshed with the ring gear 84, and the ring gear 84 is fixedly connected to the rotating seat 6, the output shaft of the drive motor 2 drives the first gear 81 to rotate, the first gear 81 drives the second gear 82 to rotate, the third gear 83 drives the rotating seat 6 to rotate by meshing with the ring gear 84, and the rotating seat 6 drives all the brushes 7 to clean the surface of the airbag 15; the diameter of the first gear 81 is larger than that of the second gear 82, and the diameter of the second gear 82 is larger than that of the third gear 83, which can increase the transmission ratio, make the rotating seat 6 rotate faster, and have a stronger cleaning effect of the brush 7.

[0040] In the embodiment of the present invention, Figure 1 As shown, as a preferred embodiment of the present invention, the filter plate 11 is provided with a plurality of arc-shaped scraping openings 17, and cleaning the brush 7 through the arc-shaped scraping openings 17 can increase the cleaning effect of the brush 7; two filter plates 11 are fixedly connected to the collection tank 10, and the arc-shaped scraping openings 17 on the two filter plates 11 are arranged opposite to each other, so that when the rotating seat 6 rotates forward and backward, the filter plates 11 can clean the brush 7.

[0041] In the embodiment of the present invention, Figure 1 As shown, as a preferred embodiment of the present invention, two adjusting screws 18 are provided between the shell 1 and the end cover. The two adjusting screws 18 and the output shaft of the drive motor 2 are arranged in a triangle. By rotating the adjusting screws 18, the distance between the shell 1 and the end cover can be increased. Then, the drive motor 2 is started to switch the positions of the valve plate 3 and the conducting ring 4, thereby realizing the conduction and closing of the pipeline. After the switching is completed, the adjusting screws 18 are rotated in the opposite direction to reclose the shell 1 and the end cover.

[0042] In the embodiment of the present invention, Figure 1As shown, as a preferred embodiment of the present invention, a pressure valve 19 is provided at the oil pipe 14. When the end cover is tightly closed with the housing 1, the pressure valve 19 is closed under pressure. When the end cover is separated from the housing 1, the pressure valve 19 is opened. By controlling the opening and closing of the pressure valve 19 by the opening and closing of the end cover and the housing 1, the oil output can be carried out when the positions of the valve plate 3 and the guide ring 4 are switched, thereby effectively controlling the oil volume and saving resources.

[0043] In the embodiment of the present invention, Figure 1 As shown, as a preferred embodiment of the present invention, the airbag 15 is connected to an air pump 16; when the valve plate 3 and the conducting ring 4 are switched in position, the airbags 15 on the front and back sides of the valve plate 3 and the conducting ring 4 are first extracted by the air pump 16, thereby avoiding contact between the airbag 15 and the outer shell 1 and the end cover on both sides, increasing the surface wear of the airbag 15, and at the same time, after the air in the airbag 15 is discharged, the contact area between the airbag 15 and the brush 7 can be increased, thereby increasing the cleaning effect of the outer surface of the airbag 15.
