Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of check valve assembly, in particular to a check valve seat assembly equipment. BACKGROUND

[0002] The check valve is an automatic valve, also known as a non-return valve, a one-way valve or a backflow valve, which is mainly used to allow fluid (liquid or gas) to flow smoothly in one direction, while preventing fluid from flowing in the opposite direction. Its basic working principle is to use the pressure of the fluid itself to open and close the valve. When the fluid flows in the normal direction, the fluid pressure will overcome the resistance inside the valve, opening the valve to allow the fluid to flow smoothly. When the fluid tries to flow in the opposite direction, the valve will automatically close under the action of fluid pressure and its own structural characteristics, preventing backflow.

[0003] In the field of industrial fluid transportation, check valves play a crucial role as key components that ensure the stable flow of fluid in one direction. They are widely used in petroleum and chemical industries, water supply and drainage, heating, ventilation and air conditioning, and power industries. The valve seat, one of the core components of the check valve, directly relates to the sealing performance, reliability and service life of the entire check valve.

DETAILED DESCRIPTION

[0033] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work belong to the scope of protection of the present application.

[0034] Please refer to Figures 1-6 ​A check valve seat assembly device includes a lowering cylinder 1, a valve seat transport assembly 2 mounted on one side of the lowering cylinder 1, and a valve seat distribution assembly 3 linked above the valve seat transport assembly 2. The valve seat transport assembly 2 includes a vertical plate 201 and a movable plate 203, and the movable plate 203 moves inside the vertical plate 201. A liftable connecting rod 206 is provided on the movable plate 203, and the bottom end of the connecting rod 206 clamps the valve seat through a clamp 207. A first hinge rod 208 and a second hinge rod 209 are hinged to one side of the movable plate 203, and the second hinge rod... A pulley assembly 302 is connected to the rear side of the rod 209. The pulley assembly 302 drives the worm gear assembly to rotate, and the worm gear assembly drives the rack 309 to move through the gear combination. One end of the rack 309 is hinged to the first hinge shaft 310, and both ends of the first hinge shaft 310 are hinged to the hinge blocks 311. One end of the hinge block 311 is hinged to the second hinge shaft 313. A hinge plate 312 is connected above the middle position of the hinge block 311, and the hinge plate 312 and the hinge block 311 rotate to realize the material distribution and unloading of the stacked valve seats.

[0035] In this embodiment, the pressure cylinder 1 can be a pneumatic cylinder, hydraulic cylinder, or other telescopic device. It can apply pressure from top to bottom, using the pressure to press down the valve seat located inside the valve body, causing the valve seat to move to the expected installation position. There is generally an annular groove for installing the valve seat inside the valve body. When the valve seat is pressed down, it will deform to a certain extent due to its metallic properties, and then be installed inside the annular groove. The annular groove is also provided with a matching sealing structure. Therefore, after the valve seat is assembled inside the valve body, a stable sealing result will naturally be formed. The assembled valve seat is not the last step in the valve installation process. Later, the valve core needs to be installed on the valve seat, and the valve stem needs to be installed on the valve core, etc. The position of the pressure cylinder 1 on one side of the vertical plate 201 is above the longitudinal part of the moving groove 202. The extension position of the output end of the pressure cylinder 1 is the processing position. The transported valve body is placed in this position, and the output end of the pressure cylinder 1 presses down to accurately install the valve seat inside the valve body.

[0036] Specifically, a groove with a ramp is provided on one side of the upright plate 201, and the upper and lower ends of the movable plate 203 are connected to blocks with ramps. The movable plate 203 moves in front of the upright plate 201 through matching ramp blocks and ramp grooves. A movable groove 202 is provided on the upright plate 201, and the movable groove 202 includes a horizontal part and a vertical part, with the vertical part located at one end of the horizontal part, and the horizontal part and the vertical part are set at a 90-degree angle, with the vertical part facing downward.

[0037] In this embodiment, the groove and block with ramps can limit the movement of the moving plate 203, allowing it to move smoothly in front of the upright plate 201 without falling. The longitudinal part of the moving groove 202 is located on the side of the downward pressing direction of the pressing cylinder 1. When the moving block 205 drives the connecting rod 206 to move to the longitudinal part, it does not contact the output end of the pressing cylinder 1 and will not affect each other. When the output end of the pressing cylinder 1 needs to press down, the moving block 205 and the connecting rod 206 have already left the longitudinal part, so they will not affect the downward pressing of the pressing cylinder 1.

[0038] Specifically, the movable plate 203 is provided with an inclined groove 204, which is inclined downward. A movable block 205 is connected through the inclined groove 204. The movable block 205 also passes through the movable groove 202. The movable block 205 is located at one end of the connecting rod 206 and moves inside the movable groove 202 and the inclined groove 204.

[0039] In this embodiment, the transverse and longitudinal portions of the moving groove 202 are designed to cooperate with the inclined groove 204. The purpose is to allow the moving block 205 to move laterally and then press down, causing the clamped valve seat to be pressed into the corresponding valve body. In general equipment, this process requires two power components, one for lateral movement and one for pressing down, or only the valve seat can be moved laterally while the pressing down is done by the pressing cylinder 1. Both methods of loading have their drawbacks. Using two power components not only wastes energy but also risks the installation position overlapping with that of the pressing cylinder 1. Equipment that only moves the valve seat laterally directly completes the assembly by pressing down with the pressing cylinder 1, thus reducing the margin of error. If the valve seat is tilted or slightly misaligned, it will be directly pressed down by the pressing cylinder 1, resulting in a high workpiece damage rate. However, the device in this invention can adjust the valve seat in the valve body by pressing down with the clamp 207. The valve seat will not be tilted when entering the valve body, and the pressing process will not cause the valve seat to tilt, thus improving the yield. In this embodiment, the length of the longitudinal part of the moving groove 202 matches the position of the annular groove in the valve body. The distance that the clamp 207 penetrates into the valve body is above the annular groove. In this embodiment, the clamp 207 can be an internal support clamping device to support and fix the valve seat from the inside, without affecting the placement of the valve seat into the valve body.

[0040] Specifically, a first hinge rod 208 is connected to one side of the movable plate 203 via a hinge seat, and a second hinge rod 209 is hinged to one end of the first hinge rod 208. The second hinge rod 209 is installed on one side of the drive motor 210, and a pulley set 302 is connected to the output end of the drive motor 210.

[0041] In this embodiment, the first hinge rod 208 and the second hinge rod 209 are located on the front side of the upright plate 201. Rotating the second hinge rod 209 ensures that the first hinge rod 208 will not interfere with the falling valve seat when it rotates. This is because a stop shaft is provided between the mounting plate 301 and the receiving platform 314. The stop shaft is arc-shaped and located on the outside of the receiving platform 314. When the first hinge rod 208 rotates on one side of the stop shaft, the falling valve seat will move inside the arc-shaped stop shaft. The valve seat falling onto the receiving platform 314 will be... The clamp 207 with internal support can set the receiving platform 314 as a two-step frustum structure. The lower frustum holds the valve seat, and the upper frustum is located at the center of the valve seat. However, the upper frustum does not penetrate the valve seat, but protrudes slightly on the lower frustum, which serves as a limit while not hindering the clamping of the clamp 207. On this basis, a set of slightly downward vertical protrusions can be set at the other end of the horizontal part of the moving groove 202 to satisfy the purpose of clamping the valve seat on the receiving platform 314 by the clamp 207.

[0042] Specifically, the valve seat distribution assembly 3 includes a mounting plate 301, which is located above the vertical plate 201. The first hinge shaft 310 has an opening in the middle, matching the size of the valve seat. The pulley assembly 302 includes two sets of pulleys and a belt wound around their outer sides. One set of pulleys is located on one side of the drive motor 210, and the other set of pulleys is located on one side of the mounting plate 301. A worm gear 303 is connected to one side of the pulley assembly 302, and a worm wheel 304 meshes with one side of the worm gear 303. The upper part of the worm wheel 304... A first gear 305 is connected to the first gear 305 via a shaft, and a first half gear 306 is provided above the first gear 305. A second gear 307 is meshed on one side of the first gear 305, and a second half gear 308 is provided above the second gear 307. The second half gear 308 and the first half gear 306 face different directions, and both the first half gear 306 and the second half gear 308 mesh with the rack 309. A receiving platform 314 is provided below the first hinge shaft 310, and a stop shaft is provided between the receiving platform 314 and the mounting plate 301.

[0043] In this embodiment, the drive motor 210 is a servo motor, which drives the pulley assembly 302 to rotate while also driving the second hinge rod 209 to rotate. The shaft extending from the middle of one set of pulleys in the pulley assembly 302 is connected to the second hinge rod 209. The drive motor 210 rotates in one direction, and because of the second hinge rod 209 and the first hinge rod 208, it drives the moving plate 203 to move back and forth. Meanwhile, the rack 309 in the valve seat dispensing assembly 3 is driven back and forth by two sets of half gears facing different directions, without the need for a motor. Repeatedly adjusting the rotation direction can extend the service life of the motor. During the process of the pulley assembly 302 driving the worm 303 to rotate, and the worm 303 driving the worm wheel 304 to rotate, the transmission between the worm 303 and the worm wheel 304 also plays the role of preventing reverse rotation. The worm 303, worm wheel 304, first gear 305, and second gear 307 are all set inside the mounting plate 301. The mounting plate 301 has a groove, and the first half gear 306 and the second half gear 308 extend out of the groove and mesh with the rack 309.

[0044] Specifically, the rack 309 includes a rack portion and a rotating shaft portion, which are hinged together. The rotating shaft portion is located at one end of the rack portion, and the first hinge shaft 310 is hinged to the rotating shaft portion. There are four sets of hinge blocks 311, and each hinge block 311 includes a first arc portion 3111, a second arc portion 3112, and an inclined baffle 3113. The first arc portion 3111, the second arc portion 3112, and the inclined baffle 3113 are integrally formed. The first arc portion 3111 and the second arc portion 3112 are each provided with a hinge seat, which is connected to the first hinge shaft 310 and the second hinge shaft 313 through the hinge seat. The inclined baffle 3113 contacts the valve seat. The first arc portion 3111, the second arc portion 3112, and the inclined baffle 3113 have a "Y" shaped structure.

[0045] In this embodiment, the movement trajectory of the rack portion in the rack 309 is a straight line, but the movement trajectories of the rotating shaft portion and the first hinge shaft 310 are not necessarily straight lines. The positions of the four sets of hinge blocks 311 have been positioned, so the power of the rack 309 only needs to make the four sets of hinge blocks 311 rotate at a certain angle. The position of the four sets of hinge blocks 311 on the mounting plate 301 is the place where the hinge block 311 is installed in the middle. The hinge block 311 and the hinge plate 312 rotate around the axis as a whole.

[0046] Specifically, there are four sets of hinge baffles 312, all of which rotate with the hinge block 311. There are three sets of second hinge shafts 313, and the three sets of second hinge shafts 313 and one set of first hinge shafts 310 are arranged in a rectangular shape on the outside of the valve seat.

[0047] In this embodiment, the hinged baffle 312 is located above the hinged block 311, which is exactly the thickness of a valve seat. The hinged baffle 312 and the inclined baffle 3113 have an angle difference in the vertical direction. Therefore, when the inclined baffle 3113 contacts the bottom valve seat, the hinged baffle 312 is located on one side of the previous valve seat. After the angle is rotated, the lower valve seat is not blocked and falls through the middle through hole of the mounting plate 301. The hinged baffle 312 rotates and moves to the bottom of the adjacent valve seat, blocking the valve seat from falling further. The timing of the valve seat falling meets the timing of the clamp 207 loading.

[0048] Please see Figures 6-9 A check valve seat assembly device is provided. A transport platform 4 is installed on one side below the valve seat transport assembly 2, and a valve body transport assembly 5 is installed on the transport platform 4. The valve body transport assembly 5 includes a first clamping plate 501 and a second clamping plate 502. A crossbar 504 is provided on the rear side of both the first clamping plate 501 and the second clamping plate 502. The crossbar 504 moves laterally on the through block 505. A fixing block 509 is connected to the bottom end of the through block 505 and moves longitudinally on the fixing block 509. A rotating shaft 512 is rotated at the middle position on one side of the fixing block 509. The through shaft 514 passing through the rotating shaft 512 moves in a rectangular groove 511 below. The through shaft 514 passes through a transverse groove block 508 above and drives the through block 505 to move.

[0049] In this embodiment, the valve bodies on the transport table 4 are distributed at certain intervals. Each movement of the first clamping plate 501 and the second clamping plate 502 along a rectangular trajectory will cause the clamped valve body to shift once, so that the valve body located at one end of the transport table 4 gradually moves until it moves to the processing position, which is directly below the pressing cylinder 1. After processing is completed, the valve body will also be moved to the belt conveyor for normal unloading. The belt conveyor is flush with the transport table 4. The pressing frequency of the pressing cylinder 1 needs to be matched with the moving speed of the valve body transport assembly 5. A controller is installed in the device, which directly controls the operation of the electronic components in the device, such as the rotary motor 515 and the pressing cylinder 1. The movement speed between the rotary motor 515 and the pressing cylinder 1 is also adjusted by the controller.

[0050] Specifically, the first clamping plate 501 and the second clamping plate 502 are symmetrically arranged and have the same structure. A curved surface is provided between the first clamping plate 501 and the second clamping plate 502, and the curved surface contacts the valve body. A connecting block 503 is connected to the rear side of both the first clamping plate 501 and the second clamping plate 502, and a crossbar 504 is provided on one side of the connecting block 503.

[0051] In this embodiment, a curved surface is provided between the first clamping plate 501 and the second clamping plate 502 to better clamp the curved valve body. The part of the valve body through which the valve stem passes is located in the middle and does not directly contact the first clamping plate 501 and the second clamping plate 502. Anti-slip rubber can be provided between the first clamping plate 501 and the second clamping plate 502 to better clamp the valve body. The operation process of the second clamping plate 502 is the same as that of the first clamping plate 501. The second clamping plate 502 is driven by the pulley assembly located at the output end of the rotary motor 515.

[0052] Specifically, a transverse groove 506 is provided above the through block 505, and a longitudinal groove 507 is provided below the through block 505. The crossbar 504 moves inside the transverse groove 506, and the through block 505 moves above the fixed block 509 through the longitudinal groove 507. There are two sets of through blocks 505, and a transverse groove block 508 connects the two sets of through blocks 505.

[0053] In this embodiment, when the rotating shaft 512 rotates, it will drive the through shaft 514 to rotate. The through shaft 514 moves inside the limiting groove 513 and is restricted by it to rotate. The lower end of the through shaft 514 is located inside the rectangular groove 511, so it is also restricted by its shape. The top end of the through shaft 514 is located in the groove inside the crossbar 504, so the movement of the through shaft 514 will also drive the crossbar 504 to move. Through the cooperation of the transverse groove and the longitudinal groove, the first clamping plate 501 and the second clamping plate 502 move along a rectangular trajectory. The rectangular groove 511 has an arc at the rectangular edge to facilitate the movement of the through shaft 514. During the rotation of the through shaft 514, the mounting block 510 and the fixing block 509 do not move.

[0054] Specifically, a mounting block 510 is connected to one side of the fixing block 509, and a rectangular groove 511 is provided inside the mounting block 510. A rotating shaft 512 is rotated in the middle of the rectangular groove 511, and a limiting groove 513 is provided inside the rotating shaft 512. A through shaft 514 passes through the limiting groove 513 and passes through the transverse groove block 508 and extends to the bottom of the crossbar 504. A limiting groove is provided at the bottom end of the crossbar 504. A rotary motor 515 is installed at the bottom end of the mounting block 510, and a pulley set is connected to the output end of the rotary motor 515. The other end of the pulley set is located below the second clamping plate 502. A belt conveyor assembly is provided at one end of the transport table 4, and a processing station is provided above the transport table 4 below the pressing cylinder 1.

[0055] In this embodiment, a rotary motor 515 is installed inside the transport platform 4, and a slot is provided on the transport platform 4 for parts such as the through shaft 514 and the through block 505 to move. The crossbar 504 and the connecting block 503 are located outside the slot.

[0056] During use, an external power supply is required to provide electrical energy for the device to operate normally. First, the valve seats stacked on top of the mounting plate 301 are distributed by the valve seat distribution assembly 3. The drive motor 210 is then started, causing the pulley assembly 302 to rotate. The pulley assembly 302 drives the worm gear 303 to rotate, which in turn drives the worm wheel 304 meshing with it. The worm wheel 304 drives the upper first gear 305 to rotate. The first gear 305 drives the first half gear 306 to rotate, simultaneously driving the meshing second gear 307 to rotate. The second gear 307 then drives the upper second half gear 308 to rotate, causing the first half gear 306 and the second half gear 308 to rotate simultaneously. However, the first half gear 306 and the second half gear 308 face different directions, so they will not simultaneously contact the rack 309. When the first half gear 306 contacts the rack 309, it will drive the rack 309... When the second half gear 308 contacts the rack 309, it will drive the rack 309 to move backward. The different movement directions of the rack 309 will drive the change of the movement direction of the first hinge shaft 310. The movement of the first hinge shaft 310 will drive the front and rear sets of hinge blocks 311 to rotate. Through the connection between the multiple sets of hinge blocks 311 and hinge baffles 312, all the hinge blocks 311 surrounding the outside of the valve seat will rotate. When the four sets of inclined baffles 3113 are at the bottom of the valve seat, they will block the descent of the valve seat. At this time, the hinge baffles 312 are located on one side of the valve seat. When the hinge blocks 311 are rotated, all the inclined baffles 3113 rotate away from the bottom of the bottom valve seat, causing the bottom valve seat to fall into the receiving table 314 through the middle through hole of the mounting plate 301. At this time, the hinge baffles 312 rotate to the bottom of the adjacent valve seat, which obstructs the material discharge channel and completes the material discharge of the valve seats one by one.

[0057] When the pulley assembly 302 rotates, the second hinge rod 209 on one side of the pulley assembly 302 will also be driven to rotate. The first hinge rod 208 drives the moving plate 203 to move in front of the vertical plate 201, so that the clamp 207 moves to the top of the receiving table 314 and starts to clamp the valve seat. The continued rotation of the second hinge rod 209 will drive the moving plate 203 to move laterally on one side of the vertical plate 201. When it moves to the longitudinal part of the moving groove 202, the moving block 205 will move downward with the cooperation of the longitudinal groove and the inclined groove 204, driving the connecting rod 206, the clamp 207 and the clamped valve seat to move downward together, so that the valve seat moves down into the valve body located in the processing position on the transport table 4. The clamp 207 releases the clamp and moves back along the original path as the second hinge rod 209 continues to rotate. The upper pressing cylinder 1 presses down at this time, pressing down the valve seat located in the valve body, so that it enters the valve body installation position, completing the assembly of the valve seat.

[0058] The assembled valve seat is carried and clamped by the valve body transport assembly 5 onto the belt conveyor for unloading. This process involves the starting rotary motor 515 driving the rotating shaft 512 to rotate, which in turn drives the through shaft 514 to rotate. The lower end of the through shaft 514 is confined within the rectangular groove 511, so it can only move along a rectangular trajectory. The upper end of the through shaft 514 is located inside the transverse groove block 508, so the movement of the through shaft 514 simultaneously moves the transverse groove block 508, causing the through block 505 to move on the fixed block 509. The top end of the through shaft 514 is confined within the groove inside the crossbar 504. Therefore, when the through shaft 514 moves, it will also drive the crossbar 504 to move above the through block 505. The movement of the two will cause the first clamping plate 501 to move along a rectangular movement trajectory, so that the two sets of opposing first clamping plates 501 and second clamping plates 502 move together towards the middle to clamp the valve body, and then drive the clamped valve body to move, gradually moving closer to the direction of the lower cylinder 1. Then the first clamping plate 501 and second clamping plate 502 move back to release the clamped valve body, and then move back to the original position. Repeat this step to transport the valve bodies arranged in sequence to the processing station one by one, and at the same time transport the processed valve bodies to the belt conveyor for loading and unloading.
