Description

Technical Field

[0002] This invention belongs to the field of valve and sealing technology, specifically relating to a sealing method and device based on a spiral. Background Technology

[0004] 1. Valves are devices used in fluid systems to control the direction, pressure, and flow rate of fluids. They are devices that allow the medium (liquid, gas, powder) in piping and equipment to flow or stop and control its flow rate.

[0005] Valves are control components in pipeline fluid transport systems, used to change the cross-sectional area of ​​the passage and the direction of medium flow. They have functions such as guiding, stopping, throttling, checking back, diverting, or overflowing and relieving pressure. Valves used for fluid control range from the simplest shut-off valves to various valves used in extremely complex automatic control systems. Their types and specifications are numerous, with nominal diameters ranging from extremely small instrument valves to industrial pipeline valves with diameters up to 10 meters. They can be used to control the flow of various types of fluids, including water, steam, oil, gas, slurry, various corrosive media, liquid metals, and radioactive fluids.

[0006] 2. The caps of semi-solid products such as lipsticks, lip balms, and glue sticks are usually detachable. This type of sealing structure also includes camera lens caps and pen caps.

[0007] The existing problems are as follows:

[0008] 1. Regarding valves and camera apertures, the protruding parts along the pipeline cross-section are too large, or protrude too much outward, making them difficult to install in certain narrow spaces or difficult to operate after installation. The inward protrusion is too large, and most valves do not take into account the non-destructive passage of semi-solid or solid substances.

[0009] 2. In terms of sealing, the caps of semi-solid or solid products such as lipsticks, lip balms, and glue sticks, as well as camera lens caps and pen caps, are mostly designed separately, making them impossible to operate with one hand, cumbersome to use, and easy to lose.

[0010] Therefore, it is particularly important to design a method that is easy to operate in confined spaces and can pass semi-solid and solid materials without damage. At the same time, this method can provide a solution to the problem of inconvenient operation of the sealing device with a separate design. Summary of the Invention

[0012] This invention provides a spiral-based sealing method and device that employs radial control. It solves the problem that independent thin-walled devices cannot be used for sealing in related technologies, as well as the problems of excessive protrusion of the control part from the fluid pipe wall and the problem of allowing tangible objects to pass through the valve without damage in related technologies.

[0013] According to one aspect of the present invention, a spiral-based sealing method is provided, comprising the following steps:

[0014] Step S1: The sealing surface based on the spiral is a complete sealing surface formed by two adjacent spirals starting from the pole, arranged sequentially along the circumference.

[0015] Step S2: The spiral surface is driven and connected to the control unit. The control unit provides actuating force to the spiral surface. The control unit generates an action, and the spiral surface follows the control unit along a radial spiral track to rotate out of the control unit, completing the closing action of the spiral-based sealing surface.

[0016] Step S3: The control unit generates an action, the spiral surface follows the movement of the control unit, and the spiral surface rotates into the control unit along a radial spiral track to complete the opening action of the spiral-based sealing surface.

[0017] Furthermore, the helical surface has a closed end and a control end, and the helical surface extending axially from the closed end to the control end is a helix of equal diameter.

[0018] The spiral-based sealing surface is composed of at least two spiral surfaces arranged sequentially along the circumference. When the closed ends of the spiral surfaces are closed, they converge inward to form the spiral-based sealing surface centered on the pole.

[0019] The spiral surfaces arranged sequentially along the circumference fit together at the spiral-based sealing surface.

[0020] Furthermore, the control unit provides a helical groove track for the helical surface.

[0021] The control unit has a control element connected to the control end of the spiral surface. When the control element performs an action, the spiral surface will move along the spiral groove track. When sealing, the closed end of the spiral surface rotates out of the spiral groove track, and when opening, the spiral surface rotates into the spiral groove track.

[0022] Furthermore, the control unit and the spiral-based sealing surface together form a sealed cavity structure when the spiral-based sealing surface forms a complete closed surface.

[0023] According to another aspect of the present invention, a spiral-based sealing device is provided, comprising: a circular groove cap, a spiral sealing surface assembly, a spiral groove outer tube, and a rear sealing rotating assembly.

[0024] The circular groove cap is fixedly connected to the spiral groove outer tube, and the rear-closed rotating assembly is rotatably connected to the spiral groove outer tube.

[0025] The circular groove cap, the spiral groove outer tube, and the rear-closed rotating assembly together form a cavity structure, in which the spiral sealing surface assembly is placed.

[0026] Furthermore, the circular slot cover 1 is cylindrical with a circular through slot at its center.

[0027] The spiral closed surface assembly consists of at least two single spiral belts and a limiting transmission tube.

[0028] The outer tube of the spiral groove is a circular hollow tube with a spiral groove, a circular limiting groove A, and a circular limiting groove B on its inner wall.

[0029] The rear-closed rotating assembly includes a double-tooth drive tube and a rectangular groove rotating rear cover.

[0030] Furthermore, the outer surface of the circular slot cover is annular, and the inner surface is provided with a track slot that satisfies the rotation of the single spiral band within the spiral closed surface assembly.

[0031] The single spiral band is an equal-diameter spiral in the axial direction, and the single spiral bands in the spiral closed surface group are spiral bands of equal width, which can provide a continuous matching state between the single spiral bands arranged sequentially along the circumference. When converging towards the pole, due to the limitation of the width of the spiral band, a regular polygon is formed near the pole, and it cannot completely converge at one point. Therefore, the closed end has a fan-shaped protrusion with the width of the single spiral band as the radius. The proximal side of the fan-shaped protrusion is replaced by an arc of the same radius, and the central angle of the fan-shaped protrusion satisfies the sum of the exterior angle of the regular polygon and 1 / 2 of the interior angle.

[0032] The formula for the interior angle of a regular polygon is: Interior angle measure = (n-2)×180° / n, where n is the number of sides (n≥3).

[0033] The formula for the exterior angle of a regular polygon is: Exterior angle measure = 360° / n, where n is the number of sides (n≥3).

[0034] The formula for adding 1 / 2 of an interior angle to an exterior angle is: exterior angle + ½ × interior angle = (360° / n) + ½ [(n-2) × 180° / n] = 90° + 180° / n, where n is the number of sides (n≥3).

[0035] Converting this formula to radians, we get: θ = π / 2 + π / n, where (n ≥ 3).

[0036] Let the radius of the circle be R, the central angle be θ, the arc length be L, the width of the single helical strip be d (R=d), the number of single helical strips be n, and the arc length of the fan-shaped protrusion at the closed end of the single helical strip be L=R(π / 2+π / n)=d(π / 2+π / n) where (n≥3).

[0037] The cross-section of the single helical band is rectangular, with inwardly concave semi-circular notches on the inner side and outwardly convex semi-circular protrusions on the outer side. The notches and protrusions of two adjacent single helical bands coincide.

[0038] Furthermore, the wall of the limiting transmission tube has two through rectangular toothed grooves and an elastic limiting block. The elastic limiting block is a rectangular elastic block cut out of the wall of the limiting transmission tube. The movable end has a hemispherical protrusion along the outer side of the tube wall. The non-groove end of the limiting transmission tube is fixedly connected to the single spiral belt.

[0039] The spiral groove on the inner sidewall of the spiral grooved outer tube matches the track groove in the circular grooved cover. The number of spiral grooves on the inner sidewall of the spiral grooved outer tube is the same as the number of single spiral bands, and can accommodate the single spiral bands.

[0040] The circular limiting groove B has the same radius as the circular limiting groove A. The depth of the circular limiting groove B is half that of the circular limiting groove A, and the volume of the circular limiting groove A is sufficient to fit and accommodate the hemispherical protrusion along the outer side of the pipe wall of the movable end of the elastic limiting block.

[0041] Furthermore, the double-tooth transmission tube has a cylindrical structure with two columnar teeth stretched out at one end. The columnar teeth are inserted into the rectangular tooth groove. The inner diameter of the double-tooth transmission tube allows the rectangular groove to rotate and the cover to pass through. The rectangular groove rotates and the cover drives the double-tooth transmission tube to rotate through a spiral clutch.

[0042] The rectangular groove rotating cover is composed of a cylinder with a rectangular groove cut into its outer wall and a closed cylinder. The rectangular groove allows the elastic limiting block to be inserted.

[0043] The rectangular groove rotating cover can rotate relative to the spiral groove outer tube.

[0044] The rectangular groove rotating cover can be engaged or disengaged from the limiting transmission tube by changing the positions of the circular limiting groove B, the circular limiting groove A and the elastic limiting block.

[0045] Furthermore, the rectangular groove rotating cover drives the limiting transmission tube to rotate by changing the positions of the circular limiting groove B, the circular limiting groove A and the elastic limiting block, and the rotation of the limiting transmission tube causes the spiral sealing surface assembly to open.

[0046] The rectangular groove rotating cover drives the double-tooth transmission tube to rotate via a spiral clutch. The double-tooth transmission tube drives the limiting transmission tube to rotate, and the rotation of the limiting transmission tube causes the spiral sealing surface assembly to close.

[0047] The spiral-based sealing method and device provided by this invention solves the problem in related technologies that the protruding part of the valve along the pipeline cross section is too large, making it difficult to configure in some narrow spaces or difficult to operate later after configuration. Most valves do not consider the problem of non-destructive passage of semi-solid or solid substances.

[0048] This solves the problem of cumbersome handling and easy loss of semi-solid or solid products such as lipsticks, lip balms, and glue sticks, as well as camera lenses and pens, which use openable and closed caps. Attached Figure Description

[0073] The technical solutions of the embodiments of the present invention are clearly and completely described below through specific examples. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0074] This embodiment provides a sealing method based on a spiral. Figure 2 is a schematic diagram of spiral surface closure according to an embodiment of the present invention. Figures 2 to 8 As shown, the method includes:

[0075] Step S1: The sealing surface based on the spiral is a complete sealing surface formed by two adjacent spirals starting from the pole, arranged sequentially along the circumference.

[0076] Step S2: The spiral surface is driven to connect with the control unit. The control unit provides actuating force to the spiral surface, and the control unit generates an action. The spiral surface follows the control unit and rotates out of the control unit along a radial spiral track, completing the closing action of the spiral-based sealing surface.

[0077] Step S3: The control unit generates an action, and the spiral surface follows the movement of the control unit. The spiral surface rotates into the control unit along the radial spiral track to complete the opening action of the sealing surface based on the spiral line.

[0078] Through the above steps, a closed surface is formed by the spiral movement of the spiral surface along the radial track. This avoids the inconvenience or unachievable effect of the control part protruding too much from the fluid pipe wall in the prior art, as well as the problem of sealing using independent thin-walled devices that cannot be solved in the prior art. This provides a new valve and sealing method.

[0079] There are many types of spiral surfaces generated in a spiral closed surface. Regardless of which spiral surface is used, the sealing effect can be achieved. As long as the spiral surfaces can fit and connect at the closed surface, the problems in the existing technology can be solved and the corresponding effect can be achieved.

[0080] This embodiment provides an implementation method.

[0081] A complete closed surface is obtained by changing the shape of the tip of the spiral band in the convergence area by converging the helical surfaces of equal width at the center.

[0082] According to one aspect of the invention, referring to Figures 2 to 8As shown, this embodiment provides a sealing method based on a spiral, including the following steps:

[0083] Step S1: The sealing surface based on the spiral is a complete sealing surface formed by two adjacent spirals starting from the pole, arranged sequentially along the circumference.

[0084] Step S2: The spiral surface is driven and connected to the control unit. The control unit provides the spiral surface with the action force, and the control unit generates the action. The spiral surface follows the movement of the control unit to complete the closing action of the sealing surface based on the spiral line.

[0085] Step S3: The control unit generates an action, and the spiral surface follows the movement of the control unit to complete the opening action of the sealing surface based on the spiral line.

[0086] Preferred, such as Figure 4 Figure 5 As shown, the helical surface has a closed end and a control end, and the helical surface extending axially from the closed end to the control end is a helix of equal diameter.

[0087] A spiral-based sealing surface consists of at least two spiral surfaces arranged sequentially along the circumference. The spiral surfaces are made of a tough material that can produce the required deformation. When the closed ends of the spiral surfaces are closed, they converge inward to form a spiral-based sealing surface centered on the pole.

[0088] like Figure 1 Figure 5 The spiral surfaces arranged sequentially along the circumference shown are connected at the sealing surface based on the spiral line.

[0089] More preferably, such as Figure 6 Figure 7 Figure 14 As shown, the control unit provides a helical groove track for the helical surface.

[0090] The control unit has a control element connected to the control end of the spiral surface. When the control element performs an action, the spiral surface will move along the spiral groove track. When sealing, the closed end of the spiral surface rotates out of the spiral groove track, and when opening, the spiral surface rotates into the spiral groove track.

[0091] Preferred, such as Figure 8 The control unit shown and the spiral-based sealing surface together form a sealed cavity structure when the spiral-based sealing surface forms a complete closed surface.

[0092] According to another aspect of the invention, referring to Figure 1 As shown, this embodiment provides a sealing device based on a spiral, including: a circular groove cover 1, a spiral sealing surface assembly 2, a spiral groove outer tube 3, and a rear sealing rotating assembly 4.

[0093] The circular groove cap 1 is fixedly connected to the spiral groove outer tube 3, and the rear closed rotating assembly 4 is rotatably connected to the spiral groove outer tube 3.

[0094] The circular groove cap 1, the spiral groove outer tube 3, and the rear-sealed rotating assembly 4 together form a cavity structure, in which the spiral sealing surface assembly 2 is placed.

[0095] Preferred, refer to Figure 9 , Figure 11 As shown, the circular slot cover 1 is cylindrical with a circular through slot in the center.

[0096] Reference Figure 14 As shown, the spiral closed surface assembly 2 consists of at least two single spiral belts 21 and a limiting transmission tube 22.

[0097] Reference Figure 15 As shown, the outer tube 3 of the spiral groove is a circular hollow tube with a spiral groove 31, a circular limiting groove A32, and a circular limiting groove B33 on its inner wall.

[0098] Reference Figure 18 As shown, the rear closed rotating assembly 4 includes a double-tooth transmission tube 41 and a rectangular groove rotating rear cover 42.

[0099] Preferred, refer to Figures 11 to 13 As shown, the outer side of the circular slot cover 1 is annular, and the inner side is provided with a track slot that satisfies the rotation of the single spiral band 21 in the spiral sealing surface group 2. The single spiral band 21 is closed and opened through the path provided by this track slot.

[0100] Reference Figures 2 to 5 As shown, the single spiral band 21 is a spiral of equal diameter along its axis. The single spiral band 21 in the spiral closed surface group 2 is a spiral band of equal width, which can provide a continuous matching state between the single spiral bands 21 arranged sequentially along the circumference. When converging towards the pole, due to the limitation of the width of the spiral band, a regular polygon is formed near the pole, and it cannot completely converge at one point. Therefore, there is a fan-shaped protrusion with the width of the single spiral band 21 as the radius at the closed end. The proximal side of the fan-shaped protrusion is replaced by an arc of the same radius. The central angle of the fan-shaped protrusion satisfies the sum of the exterior angle of the regular polygon and 1 / 2 of the interior angle.

[0101] The formula for the interior angle of a regular polygon is: Interior angle measure = (n-2)×180° / n, where n is the number of sides (n≥3).

[0102] The formula for the exterior angle of a regular polygon is: Exterior angle measure = 360° / n, where n is the number of sides (n≥3).

[0103] The formula for adding 1 / 2 of an interior angle to an exterior angle is: exterior angle + ½ × interior angle = (360° / n) + ½ [(n-2) × 180° / n] = 90° + 180° / n, where n is the number of sides (n≥3).

[0104] Converting this formula to radians, we get: θ = π / 2 + π / n, where (n ≥ 3).

[0105] Let the radius of the circle be R, the central angle be θ, the arc length be L, the width of the single spiral band be d (R=d), the number of single spiral bands (21) be n, and the arc length of the fan-shaped protrusion at the closed end of the single spiral band be L=R(π / 2+π / n)=d(π / 2+π / n) where (n≥3).

[0106] For example, in this embodiment, six spiral strips are used, each with a width of d. The arc length of the fan-shaped protrusion is L=d(π / 2+π / n)=d×2π / 3, and the central angle is θ=π / 2+π / n=π / 2+π / 6=60°. The proximal side of the fan-shaped protrusion is replaced by an arc with a radius of d and a central angle of 1 / 2θ=30°, connecting the center to one end of the arc. The six spiral strips form a regular hexagon at the center with the width of the spiral strip as the side length, so that the six spiral strips are perfectly filled at the center.

[0107] Reference Figure 20 As shown, the cross-section of the single helical band 21 is rectangular, with inwardly concave semi-circular notches on the inner side and outwardly convex semi-circular protrusions on the outer side. The notches and protrusions of two adjacent single helical bands 21 coincide. (Refer to...) Figure 3 , Figure 4 As shown, the single helical band 21 is made of a tough material, which satisfies the elastic characteristics of bending towards the center when closing and returning to its original shape when opening. At the same time, the width can vary within the allowable range. When the closed ends of the single helical bands 21 converge at the center, the single helical bands 21 are connected and the helix at the connection of two adjacent single helical bands 21 is approximately an Archimedean spiral.

[0108] Preferred, refer to Figure 14 , Figure 16 , Figure 18 As shown, the limiting transmission tube 22 has two through rectangular toothed grooves 221 and an elastic limiting block 222 on its wall. The elastic limiting block 222 is a rectangular elastic block cut out of the wall of the limiting transmission tube 22. The movable end has a hemispherical protrusion along the outer side of the tube wall. The non-groove end of the limiting transmission tube 22 is fixedly connected to the single spiral belt 21.

[0109] Reference Figure 6 , Figure 8 , Figure 11 As shown, the spiral groove 31 on the inner wall of the spiral groove outer tube 3 matches the track groove in the circular groove cover 1. The number of spiral grooves 31 on the inner wall of the spiral groove outer tube 3 is the same as the number of single spiral bands 21, and can accommodate and match the single spiral bands 21. A group of single spiral bands 21 completes the closing and opening actions through this path.

[0110] Reference Figure 15As shown, the circular limiting groove B33 has the same radius as the circular limiting groove A32, the depth of the circular limiting groove B33 is half that of the circular limiting groove A32, and the volume of the circular limiting groove A32 is large enough to fit and accommodate the hemispherical protrusion along the outer side of the pipe wall of the movable end of the elastic limiting block 222.

[0111] For example, in some embodiments, the inner diameter of the spiral groove outer tube 3 can fit and accommodate the limiting transmission tube 22, the hemispherical protrusion on the outer side of the movable end of the elastic limiting block 222 can be fully inserted into the circular limiting groove A32, and half of the spherical end of the hemispherical protrusion on the outer side of the movable end of the elastic limiting block 222 can be fully inserted into the circular limiting groove B33.

[0112] Preferred, refer to Figures 17 to 19 As shown, the double-tooth transmission tube 41 has a cylindrical structure with two columnar teeth stretched out at one end. The diameter of the tube is the same as that of the limiting transmission tube 22. The columnar teeth are inserted into the rectangular tooth groove 221. The inner diameter of the double-tooth transmission tube 41 allows the rectangular groove to rotate and the cover 42 to pass through. The rectangular groove rotates and the cover 42 drives the double-tooth transmission tube 41 to rotate through a spiral clutch.

[0113] The rectangular groove rotating cover 42 is composed of a cylinder with a rectangular groove cut into its outer wall and a closed cylinder. The rectangular groove allows the elastic limiting block 222 to be inserted.

[0114] The rectangular groove rotating cover 42 can rotate relative to the spiral groove outer tube 3.

[0115] For example, in some embodiments, the rectangular groove rotating back cover 42 is connected to the double toothed transmission tube 41 via a spiral clutch, such as a common lipstick screw-out structure. It can rotate clockwise for multiple turns, and when it reaches the rotation limit counterclockwise, the rectangular groove rotating back cover 42 drives the double toothed transmission tube 41 to rotate together.

[0116] Reference Figure 15 , Figure 18 , Figure 19 As shown, the rectangular groove rotating back cover 42 can be engaged or disengaged from the limiting transmission tube 22 by changing the positions of the circular limiting groove B33, the circular limiting groove A32 and the elastic limiting block 222.

[0117] Preferred, refer to Figure 1 , Figure 9 , Figure 10 , Figures 15 to 19 As shown, after the rectangular groove rotates, the cover 42 rotates, and the positions of the circular limiting groove B33, the circular limiting groove A32, and the elastic limiting block 222 change, driving the limiting transmission tube 22 to rotate. The rotation of the limiting transmission tube 22 causes the spiral sealing surface assembly 2 to open.

[0118] The rectangular groove rotating cover 42 drives the double tooth transmission tube 41 to rotate through the spiral clutch. The double tooth transmission tube 41 drives the limiting transmission tube 22 to rotate. The rotation of the limiting transmission tube 22 closes the spiral sealing surface group 2.

[0119] For example, in this embodiment, the movable end of the elastic limiting block 222 protrudes along the outer side of the pipe wall in a hemispherical shape, and its initial position is located in the circular limiting groove B33. At this time, the inner wall of the elastic limiting block 222 is inserted into the rectangular groove of the rectangular groove rotating cover 42. The clockwise rotation of the rectangular groove rotating cover 42 drives the limiting transmission tube 22 to rotate clockwise. After the limiting transmission tube 22 rotates clockwise, two parallel actions occur:

[0120] Action 1: Drives a set of single spiral belts 21 to rotate clockwise. The set of single spiral belts 21 spirals into the outer tube 3 of the spiral groove along the spiral groove 31, achieving the opening action of the closed surface. During this process, because the single spiral belts 21 move along the spiral track, the inner wall of the elastic limiting block 222 inserts into the rectangular groove and the part of the rotating cover 42 moves a distance along the rectangular groove.

[0121] Action 2: As the cylindrical teeth of the double-tooth transmission tube 41 are inserted into the rectangular tooth groove 221, the cover 42 rotates together with the rectangular groove.

[0122] When the movable end of the elastic limit block 222 rotates along the hemispherical protrusion on the outer side of the pipe wall into the circular limit groove A32, the movable end of the elastic limit block 222 is fully inserted into the circular limit groove A32. At this time, the rectangular groove part of the rotating cover 42 after the inner wall of the elastic limit block 222 is inserted into the rectangular groove is completely ejected. At this time, the limit transmission tube 22 stops rotating, and at the same time, the rotation of the double tooth transmission tube 41 is restricted.

[0123] The rectangular groove rotating back cover 42 is connected to the double toothed transmission tube 41 through a spiral clutch. By continuing to rotate the rectangular groove rotating back cover 42, the internal protected object can be unscrewed, such as pushing out objects like lipstick or glue sticks from the closed surface.

[0124] After the rectangular groove rotates, the cover 42 rotates counterclockwise to retract the protected object. When it rotates to the limit of the spiral clutch, it drives the double tooth transmission tube 41 to rotate together. The double tooth transmission tube 41, through the connection between the double teeth and the rectangular tooth groove 221, drives the limit transmission tube 22 to rotate counterclockwise. The counterclockwise rotation of the limit transmission tube 22 completes the unspinning and closing action of a single spiral belt 21.

[0125] The movable end of the elastic limiting block 222, along the hemispherical protrusion on the outer side of the pipe wall, stops and locks when it rotates into the circular limiting groove B33. At this time, the inner wall of the elastic limiting block 222 is inserted into the rectangular groove of the rotating cover 42.
