Description

Technical Field

[0001] This invention relates to the field of valve technology, and in particular to a valve cage removal device. Background Technology

[0002] The valve cage is an important component of a valve, typically used to enhance its stability and sealing performance. Located inside the valve, the valve cage is usually made of metal and secures the valve core or ball, maintaining its stable position during operation. During valve use, the valve core and valve cage are tightly integrated, forming a unified assembly to ensure the valve's normal operation and stability.

[0003] Meanwhile, during use, the valve body develops severe scaling on its inner wall, requiring regular cleaning. Removing the valve cage during disassembly is particularly difficult. Current methods for removing the valve cage often involve multiple workers cooperating, using jacks to extract the valve core from the valve body. During this process, workers need to manually assist the jacks at the valve body flange end before using them to remove the valve core. This inconvenient operation negatively impacts worker efficiency. Summary of the Invention

[0032] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

The phrase "in one embodiment" appearing in different places throughout this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.

[0034] Example 1 Reference Figures 1-6This is the first embodiment of the present invention. This embodiment provides a valve cage removal device, which includes a clamping unit 100, including a mounting frame 101, a trapezoidal block 102 disposed inside the mounting frame 101, a first connecting plate 104 disposed on both sides of the trapezoidal block 102, a second connecting plate 105 disposed at the end of the first connecting plate 104, and a clamping plate 103 disposed at the end of the second connecting plate 105.

[0035] Preferably, the trapezoidal block 102 is slidably connected to the first connecting plate 104, and the trapezoidal block 102 can push the two sets of first connecting plates 104 to move horizontally while moving vertically; as the first connecting plate 104 moves, it can push the second connecting plate 105 to move in the same horizontal plane in a direction perpendicular to it; and the movement direction of the second connecting plate 105 is perpendicular to that of the clamping plate 103; the movement of the trapezoidal block 102 can drive the clamping plate 103 to move; thus, it can be ensured that the clamping plate 103 can clamp and fix the end of the valve body 400 of the fixed model.

[0036] Furthermore, the trapezoidal block 102 includes a first slider 102-1 disposed on both sides thereon; the first connecting plate 104 includes a first groove 104-1 opened at one end thereon, and a second slider 104-2 disposed at the other end of the first connecting plate 104; the first groove 104-1 is slidably connected to the first slider 102-1; the second connecting plate 105 includes a second groove 105-1 opened at one end thereon, and a slide rail 105-2 disposed on the surface of the second connecting plate 105; the second groove 105-1 is slidably connected to the second slider 104-2; the clamping plate 103 includes a fourth groove 103-1 opened at its end face; the slide rail 105-2 is slidably connected to the fourth groove 103-1; the trapezoidal block 102 moving in the vertical direction can drive the two sets of clamping plates 103 to move relative to each other in the horizontal direction.

[0037] Preferably, there are two sets of first sliders 102-1; the two sets of first sliders 102-1 are symmetrically arranged on both sides of the trapezoidal block 102; and the first sliders 102-1 are slidably connected to the first slide groove 104-1; the movement of the trapezoidal block 102 can push the first connecting plate 104 to move; while the first connecting plate 104 moves, the second slider 104-2 at its end can cooperate with the second slide groove 105-1, so that the first connecting plate 104 pushes the second connecting plate 105 to move; the movement of the second connecting plate 105 can push the clamping plate 103 to move along a horizontal direction perpendicular to the second connecting plate 105; with the cooperation of each set of parts, the clamping plate 103 can be moved closer or further apart by pressing the trapezoidal block 102.

[0038] Furthermore, the valve body 400; the mounting bracket 101 includes a first cavity 101-1 vertically inside it, a through hole 101-2 disposed at one end of the mounting bracket 101, a clamping hole 101-4 disposed on the side wall of the mounting bracket 101, and a limiting hole 101-5 disposed at the center of the mounting bracket 101; the second slide groove 105-1 is adapted to the through hole 101-2; the end of the second slide groove 105-1 penetrates the mounting bracket 101 and extends to its outer side; the clamping plate 103 penetrates the clamping hole 101-4 and extends to its outer side; the end face of the clamping plate 103 is in contact with the valve body 400.

[0039] Preferably, the first cavity 101-1 has a U-shaped structure; the trapezoidal block 102 and the first connecting plate 104 are located inside the first cavity 101a-1 in the horizontal direction; and the second connecting plate 105 is located inside the first cavity 101a-1 in the vertical direction; and the second connecting plate 105 is adapted to the through hole 101-2; the through hole 101-2 can limit the second connecting plate 105; thereby ensuring that the second connecting plate 105 can move in the horizontal direction; clamping. Plate 103 is adapted to clamping hole 101-4; clamping hole 101-4 can limit clamping plate 103, so that the movement of second connecting plate 105 can push clamping plate 103 to move along the inner wall of clamping hole 101-4; pressing trapezoidal block 102 can drive two sets of clamping plates 103 to move closer to each other, so that the ends of clamping plate 103 contact the two sides of valve body 400; thereby fixing the position between mounting bracket 101 and valve body 400.

[0040] Furthermore, the trapezoidal block 102 includes a connecting rod 102-2 disposed at the top, a locking member 102-3 disposed on the side wall of the trapezoidal block 102, and a first spring 102-4 disposed at the bottom of the trapezoidal block 102; the locking member 102-3 includes a second cavity 102-31 disposed on the inner side of the trapezoidal block 102, a second spring 102-32 disposed on the inner side of the second cavity 102-31, and a limiting block 102-33 disposed at the end of the second spring 102-32; the end of the limiting block 102-33 passes through the second cavity 102-31 and extends to its outer side; the end of the limiting block 102-33 passes through the limiting hole 101-5 and extends into its interior.

[0041] Preferably, the end of the connecting rod 102-2 can penetrate through the end of the mounting bracket 101 and extend to its outer side; thus, it is easier for the operator to press the trapezoidal block 102 to move vertically; and as the trapezoidal block 102 moves downward, the limiting block 102-33 is squeezed by the inner wall of the first cavity 101-1, causing the limiting block 102-33 to sink into the inner side of the second cavity 102-31; the limiting block 102-33 moves along the inner side of the second cavity 102-31. While the wall moves, the second spring 102-32 is compressed; when the position of the limiting block 102-33 corresponds to the position of the limiting hole 101-5, the limiting block 102-33 can be pushed into the limiting hole 101-5 under the rebound force of the second spring 102-32; thus, the trapezoidal block 102 can be limited by the limiting block 102-33, and the position of the trapezoidal block 102 is fixed while ensuring the position of the clamping plate 103 is fixed; thereby fixing the position of the mounting bracket 101 and the valve body 400.

[0042] In use, when the operator needs to fix the mounting bracket 101 to the outer end of the valve body 400, by pressing the trapezoidal block 102, the first slider 102-1 moves vertically, simultaneously pushing the two sets of first connecting plates 104 to move horizontally; as the first connecting plate 104 moves, it drives the second connecting plate 105 to move, and the movement of the second connecting plate 105 can push the clamping plate 103 to move. As the clamping plates 103 move closer to each other, they can clamp and fix both sides of the valve body 400; as the trapezoidal block 102 moves downward, the end of the limiting block 102-33 contacts the inner wall of the first cavity 101-1; and then... The limiting block 102-33 is inserted into the inner side of the second cavity 102-31; as the position of the limiting block 102-33 moves to the position corresponding to the limiting hole 101-5; under the rebound force of the second spring 102-32, the limiting block 102-33 is pushed into the inner side of the limiting hole 101-5; thereby fixing the clamping plate 103 on both sides of the valve body 400; thereby fixing the position between the valve body 400 and the mounting bracket 101; the mounting bracket 101 can provide a support platform for the jack body 800; thereby making it easier to separate the valve body 400 from the valve core body 500.

[0043] In summary, this invention allows the two sets of clamping plates to move in opposite directions by pressing the trapezoidal block; the two sets of clamping plates can clamp and fix the end of the valve body by bringing them closer together; thus, the mounting bracket can be fixedly set at the end of the valve body; it can better facilitate the operation of the staff; this device can reduce the number of staff; free up more labor and improve work efficiency.

[0044] Example 2 Reference Figures 1-12This is the second embodiment of the present invention, which differs from the first embodiment in that it further includes: In the previous embodiment, the valve cage removal device includes, the mounting frame 101 further includes a hinge seat 101-3 disposed at its central position; the hinge seat 101-3 includes a shaft hole 101-31 opened on its inner side, and a limiting groove 101-32 disposed on the outer side of the shaft hole 101-31; a flipping unit 200 is installed on the inner side of the hinge seat 101-3; the flipping unit 200 includes a lever 201, a push rod 202 disposed on the inner side of the lever 201, and a... The lever 201 includes a rotating plate 203 at its end, a rectangular block 204 disposed inside the rotating plate 203, a second slide rail 205 disposed on one side of the limiting hole 101-5, a second push rod 206 disposed inside the lever 201, and a limiting rod 207 disposed on the outer wall of the second push rod 206; the lever 201 also includes a rotating shaft 201-1 disposed on both sides thereon; the rotating shaft 201-1 is adapted to the shaft hole 101-31; the inside of the lever 201 is a hollow structure.

[0045] Preferably, the hinge seat 101-3 is positioned centrally within the mounting bracket 101; the end of the lever 201 is located inside the hinge seat 101-3; the lever 201 has a hollow interior, and the push rod 202 slides within the cavity of the lever 201; the rotating plate 203 rotates inside the lever 201; and as the push rod 202 moves along the interior of the lever 201, its end contacts the end of the rotating plate 203; the movement of the push rod 202 causes the rotating plate 203 to move, thereby... The rotating plate 203 can be fixed inside the lever 201, so that the rotating plate 203 can drive the rectangular block 204 to slide along the trajectory inside the second slide rail 205; and the rotating shaft 201-1 is symmetrically arranged on the side wall of the end of the lever 201; and the rotating shaft 201-1 rotates along the axis of the shaft hole 101-31; and under normal conditions, the second push rod 206 will push the limiting rod 207 out from the inside of the rotating shaft 201-1; so that the angle of the lever 201 flipping can only be within the range of the limiting groove 101-32.

[0046] Furthermore, the second push rod 206 includes a fourth spring 206-2 disposed at one end thereof, and a first inclined surface 206-1 disposed at the other end thereof; the second push rod 206 is disposed inside the rotating shaft 201-1; one end of the fourth spring 206-2 is connected to the inner wall of the rotating shaft 201-1; the rotating shaft 201-1 includes a circular hole 201-11 penetrating its side wall; the circular hole 201-11 is adapted to the limiting rod 207; the limiting rod 207 penetrates the rotating shaft 201-1 and extends to its outer side; the end of the limiting rod 207 penetrates into the inner side of the limiting groove 101-32.

[0047] Preferably, one end of the fourth spring 206-2 is fixedly connected to the second push rod 206, and the other end of the fourth spring 206-2 is fixedly connected to the inner wall of the rotating shaft 201-1. The fourth spring 206-2 can push the second push rod 206 to move, thereby allowing the second push rod 206 to push out the limiting rod 207. This allows the end of the limiting rod 207 to pass through the round hole 201-11 and extend to the outside of the rotating shaft 201-1, thereby allowing the end of the limiting rod 207 to extend to the inside of the limiting groove 101-32. This ensures that the rotation angle of the lever 201 is limited to a certain extent, thereby effectively preventing the rectangular block 204 from accidentally touching the second slide rail 205 during the flipping process of the lever 201, which would cause the trapezoidal block 102 to be unlocked. Furthermore, the mounting bracket 101 can be fixed to both sides of the end of the valve body 400.

[0048] Furthermore, the push rod 202 includes a second inclined surface 202-1 disposed on its end side wall, and a third spring 202-2 disposed on the end of the push rod 202; one end of the third spring 202-2 is connected to the inner wall of the lever 201; the second inclined surface 202-1 is in contact with the second push rod 206; the lever 201 pushes the second push rod 206 to move, so that the end of the limiting rod 207 can extend into the inner side of the rotating shaft 201-1; the connecting rod 102-2 passes through the surface of the mounting bracket 101 and extends to its outer side; the lever 201 flips its side wall to contact the top of the trapezoidal block 102.

[0049] Preferably, the end of the lever 201 has a second inclined surface 202-1 on both sides, and the surface of the second inclined surface 202-1 is in contact with the end of the second push rod 206 located inside the rotating shaft 201-1; one end of the third spring 202-2 is fixedly connected to the push rod 202, and the other end of the third spring 202-2 is fixedly connected to the inner wall of the lever 201; by pressing the push rod 202, the end face of the third spring 202-2 can be made to contact the end of the second push rod 206; thereby causing the second push rod 206 to move closer to the fourth spring 206-2; as the second push rod 206 moves, the end face of the first inclined surface 206-1 is made to contact the end of the limiting rod 207. The two parts are in contact; so that the limiting rod 207 can be inserted into the inner side of the rotating shaft 201-1 during the movement of the second push rod 206; thereby ensuring that the rotating shaft 201-1 can move along the axial direction of the shaft hole 101-31; thereby ensuring that the angle of the flip of the lever 201 increases. With the flip of the lever 201, the side wall of the lever 201 is in contact with the end of the connecting rod 102-2; during the flip of the lever 201, the connecting rod 102-2 can be pushed downward to move; thereby, the trapezoidal block 102 can be moved vertically by flipping the lever 201; at this time, the movement of the trapezoidal block 102 can drive the clamping plate to move, thereby clamping and fixing the mounting bracket 101 and the valve body 400.

[0050] Furthermore, the rectangular block 204 includes a connecting post 204-1 disposed inside it; the rotating plate 203 includes a sliding groove 203-1 disposed inside it; the rectangular block 204 is slidably connected to the second slide rail 205; the lever 201 also includes a rotating groove 201-2 disposed inside it; the rotating groove 201-2 includes a second rotating shaft 201-21 disposed on its inner wall; the end of the rotating plate 203 rotates along the axial direction of the second rotating shaft 201-21; the end of the push rod 202 contacts the end of the rotating plate 203.

[0051] Preferably, the rectangular block 204 has a U-shaped cross-section; and a connecting post 204-1 is provided on the inner side of the rectangular block 204; and the sliding groove 203-1 is adapted to the connecting post 204-1, and the connecting post 204-1 slides along the trajectory of the inner wall of the sliding groove 203-1; as the rotating plate 203 rotates, it can drive the connecting post 204-1 to move; through the cooperation of the sliding groove 203-1 and the second slide rail 205, the rectangular block 204 can be driven to move along the trajectory inside the second slide rail 205 by turning the rotating plate 203. The lever 201 is slidable; and a rotating groove 201-2 is provided at the end of the lever 201. The rotating plate 203 is adapted to the second rotating shaft 201-21. The rotating plate 203 rotates along the axis of the second rotating shaft 201-21. Under normal conditions, the lever 201 flips so that the rotating plate 203 can flip along the axis of the second rotating shaft 201-21. This ensures that the flipping of the lever 201 causes the rotating plate 203 to flip to a small extent. As a result, the flipping of the lever 201 will not push the rectangular block 204 to move to the inside of the limiting hole 101-5.

[0052] Furthermore, the side wall of the rotating plate 203 contacts the inner wall of the rotating groove 201-2; the end of the rectangular block 204 extends through to the inside of the limiting hole 101-5; the end of the rectangular block 204 contacts the end of the limiting block 102-33; and one end of the first spring 102-4 is connected to the inner wall of the mounting bracket 101.

[0053] Preferably, by pushing the push rod 202 to move, the end of the push rod 202 can contact the end of the rotating plate 203, and the push rod 202 presses the end of the rotating plate 203; causing the rotating plate 203 to rotate along the axis of the second rotating shaft 201-21; as the rotating plate 203 rotates, the side wall of the rotating plate 203 can contact the inner wall of the rotating groove 201-2, thereby limiting the rotation plate 203; as the push rod 202 moves, the end of the limiting rod 207 simultaneously enters the inner side of the rotating shaft 201-1; and then the lever... The angle of rotation of rod 201 increases, thereby causing push rod 202 to rotate and drive rectangular block 204 to move along the trajectory of second slide rail 205. This allows rectangular block 204 to push the limiting block 102-33 inside the limiting hole 101-5 to the inner wall of mounting bracket 101. At this time, the rebound force of the first spring 102-4 pushes trapezoidal block 102 to reset, thereby causing trapezoidal block 102 to reset and drive clamping plate 103 to move away from valve body 400. This facilitates the removal of mounting bracket 101 from the end of valve body 400.

[0054] In use, when the operator needs to install the mounting bracket 101 on both sides of the valve body 400 end, the mounting bracket 101 is placed on the outer side of the valve body 400 end. Then, while turning the lever 201, the push rod 202 is pressed, so that the second inclined surface 202-1 at the end of the push rod 202 can press the end of the second push rod 206 to one side. This causes the first inclined surface 206-1 to move to the position corresponding to the limiting rod 207. As the second push rod 206 moves, the end of the limiting rod 207 can extend into the inside of the rotating shaft 201-1. At this time, the lever 201 is rotated so that the rotation of the lever 201 is not restricted by the limiting groove 101-32. Then the lever 201 can be rotated so that the rotating shaft 201-1 can move along the shaft hole 101-31. Rotating along the axis, the lever 201 flips, causing its sidewall to contact the end of the connecting rod 102-2. This flip causes the trapezoidal block 102 to move vertically. Simultaneously, the trapezoidal block 102 moves the first connecting plate 104. The second slider 104-2 slides inside the second slide groove 105-1. The movement of the first connecting plate 104 pushes the second connecting plate 105 to move, causing the slide rail 105-2 to slide against the fourth slide groove 103-1. The movement of the second connecting plate 105 causes the clamping plate 103 to move. The two clamping plates 103 move towards each other, thus clamping and fixing the end of the valve body 400.

[0055] When it is necessary to release the limiting position between the mounting bracket 101 and the valve body 400, by pressing the push rod 202, the end of the push rod 202 contacts the end of the second push rod 206; thereby, the end of the limiting rod 207 can be inserted into the inner side of the rotating shaft 201-1. As the end of the push rod 202 moves, the end of the push rod 202 can contact the end of the rotating plate 203; causing the rotating plate 203 to rotate along the axial direction of the shaft hole 101-31; as the rotating plate 203 flips, the side wall of the rotating plate 203 contacts the inner wall of the rotating groove 201-2; the position of the rotating plate 203 can be limited by the cooperation between the push rod 202 and the rotating groove 201-2; at this time, the reverse lever The lever 201 can be rotated to rotate; as the lever 201 rotates, it can move the rotating plate 203, causing the rotating plate 203 to move the rectangular block 204 along the inner wall of the second slide rail 205; the rectangular block 204 slides into the limiting hole 101-5; the rectangular block 204 presses the end of the limiting block 102-33, so that the limiting block 102-33 is inserted into the inner side of the second cavity 102-31; then, under the rebound force of the first spring 102-4, it can move the first connecting plate 104, so that the clamping plate 103 can move away from the valve body 400; thus, the limitation between the mounting bracket 101 and the valve body 400 can be released.

[0056] During use, the lever 201 can be flipped directly, and the second push rod 206 is pushed to move under the rebound force of the fourth spring 206-2. This causes the second push rod 206 to push out the limiting rod 207, allowing the end of the limiting rod 207 to extend into the inner side of the limiting groove 101-32. Due to the restriction of the inner wall of the limiting groove 101-32, the flipping angle of the lever 201 is relatively small.

[0057] In summary, by pushing the push rod 202 inside the lever 201, the operator can rotate the shaft 201-1 at a large angle along the axis of the shaft hole 101-31. This allows the lever 201 to be flipped, which in turn moves the trapezoidal block 102, thereby clamping and fixing the clamping plate 103 to the end of the valve body 400. At the same time, flipping the lever 201 in the opposite direction can release the restriction between the mounting bracket 101 and the valve body 400, making the device simpler and more convenient to operate and improving work efficiency.

[0058] Example 3 Reference Figures 1-6This is the third embodiment of the present invention, which differs from the previous two embodiments in that: it includes pressing units 300 on both sides of the lever 201; the pressing unit 300 includes a connecting rod 301 and a force-applying rod 302 disposed on the outside of the connecting rod 301; the force-applying rod 302 includes a third sliding groove 302-1 disposed inside it; the lever 201 includes a third shaft hole 201-3 disposed inside it; the connecting rod 301 is adapted to the third shaft hole 201-3; the connecting rod 301 is adapted to the third sliding groove 302-1.

[0059] Furthermore, the number of pressing units 300 is two sets, and the two sets of pressing units 300 are symmetrically arranged on both sides of the lever 201; the connecting rod 301 is adapted to the third shaft hole 201-3; the connecting rod 301 rotates along the axis of the third shaft hole 201-3, and the third sliding groove 302-1 is adapted to the connecting rod 301; the connecting rod 301 slides inside the third sliding groove 302-1; as the lever 201 flips, it drives the connecting rod 301 to move along its arc track; while the connecting rod 301 moves, it can drive the force-adding rod 302 to flip; and the end of the force-adding rod 302 is connected to the lifting component of the jack body 800; as the force-adding rod 302 reciprocates by pressing and lifting, it can lift the end of the jack body 800.

[0060] Furthermore, a jack body 800 is mounted on the surface of the mounting bracket 101; a valve core body 500 is provided on the inner side of the valve body 400; a limit block 600 is installed on the top of the valve core body 500; and a top plate 700 is provided on the top of the jack body 800.

[0061] Preferably, there are two sets of jack bodies 800, and the valve core body 500 is located inside the valve body 400; the end of the valve body 400 is a screw structure, and the pressure block 600 has a screw hole inside. The pressure block 600 is threadedly connected to the end of the valve core body 500, and the top plate 700 is sleeved on the outside of the smooth rod of the valve core body 500; the end of the jack body 800 can contact the bottom of the top plate 700; as the top plate 700 is gradually lifted, it can drive the valve core body 500 inside the valve body 400 to separate, thereby realizing the disassembly of the valve core.

[0062] Furthermore, the end of the jack body 800 contacts the top plate 700; the limiting pressure block 600 is threadedly connected to the end of the valve body 400; and the end of the force-applying rod 302 is connected to the jack body 800.

[0063] Preferably, the top plate 700 is located between the top of the jack body 800 and the limiting pressure block 600; and by moving the lever 201, the two sets of force-applying rods 302 can be rotated simultaneously; thus, the force-applying rods 302 can push out the top of the jack body 800 by reciprocating rotation; as the jack body 800 moves continuously, the valve core body 500 is separated from the inside of the valve body 400; thereby realizing the removal of the valve cage.

[0064] In use, the operator places the mounting bracket 101, on which the jack body 800 is mounted, at the end of the valve body 400. The mounting bracket 101 increases the load-bearing capacity of the jack body 800, allowing for better mounting of the bracket on the outer side of the valve body 400. Then, the top plate 700 is fitted onto the outer side of the valve core body 500. The limiting pressure block 600 is then threadedly connected to the valve core body 500, thus limiting the vertical movement of the top plate 700. Through the operation of the above embodiment 2, the position of the mounting bracket 101 and the valve body 400 can be fixed. Then, by repeatedly pressing the lever 201, the force lever 302 can be moved back and forth, causing the end of the jack body 800 to be pushed out. This allows the end of the jack body 800 to contact the end face of the top plate 700, thereby pushing out the valve core body 500 inside the valve body 400 and separating the valve core body 500 from the valve body 400.

[0065] In summary, by turning lever 201, the tops of both sets of jack bodies 800 can be extended simultaneously, causing the top plate 700 to move upwards. This allows the valve core body 500 to be moved out from the inside of the valve body 400. The device is clamped on both sides of the end of the valve body 400, thereby reducing the number of operators and facilitating the disassembly of the valve cage. This reduces the labor intensity of workers and improves work efficiency to a certain extent.
