Description

Technical Field

[0001] The invention relates to the technical field of check valve assembly, in particular to a check valve seat assembly device. Background Art

[0002] A check valve is an automatic valve, also known as a non-return valve, one-way valve or reflux valve. It is mainly used to allow fluid (liquid or gas) to pass smoothly in one direction and prevent the fluid from flowing in the opposite direction. Its basic working principle is to use the fluid's own pressure to open and close the valve. When the fluid flows in the normal flow direction, the fluid pressure will overcome the resistance inside the valve, open the valve, and allow the fluid to pass smoothly; when the fluid tries to flow in the opposite direction, the valve will automatically close under the action of the fluid pressure and its own structural characteristics to prevent the fluid from flowing back.

[0003] In the field of industrial fluid transportation, check valves play a vital role. As a key component to ensure the unidirectional and stable flow of fluids, they are widely used in many industries such as petrochemicals, water supply and drainage, HVAC, and electricity. The valve seat, one of the core components of the check valve, has a directly related assembly accuracy and quality to the overall sealing, reliability, and service life of the check valve.

The device comprises a fixed table, a telescopic component, a transmission component, a support component and a sliding component; the telescopic component is arranged on the fixed table; the transmission component is arranged on the fixed table; the support component is arranged on the fixed table; the sliding component is arranged on the support component; wherein the telescopic end of the telescopic component is connected to the input end of the transmission component; wherein the output end of the transmission component is connected to the input end of the support component; the clamping mechanism is arranged on the support component; the assembly mechanism is arranged on the fixed table, which has the advantages of easy clamping and loosening of the valve seat and simple operation.

[0005] In the above-mentioned prior art, although the valve seat can be rotated in the processing gap by the joint action of the set device when clamping and loosening the valve seat without manual operation, there is no coordinated equipment for the loading and assembly of the valve seat and the valve body. In the existing valve seat and valve body processing procedures, there are three processing methods, namely threading, interference fit and welding.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] See also Figure 1-Figure 6A check valve seat assembly device includes a pressing cylinder 1, a valve seat transport component 2 is installed on one side of the pressing cylinder 1, and a valve seat material distribution component 3 is linked above the valve seat transport component 2, the valve seat transport component 2 includes a vertical plate 201 and a movable plate 203, and the movable plate 203 moves inside the vertical plate 201, a lifting connecting rod 206 is arranged on the movable plate 203, and the bottom end of the connecting rod 206 clamps the valve seat through a clamp 207, and a first hinge rod 208 and a second hinge rod 209 are hinged on one side of the movable plate 203, and the second hinge rod 209 is hinged on one side of the movable plate 203. A pulley group 302 is connected to the rear side of the rod 209, and the pulley group 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 block 311, one end of the hinge block 311 is hinged to the second hinge shaft 313, and an hinge block 312 is connected above the middle position of the hinge block 311, and the hinge block 312 and the hinge block 311 rotate in coordination to realize the material distribution and unloading of the stacked valve seats.

[0024] In this embodiment, the pressing cylinder 1 can be other telescopic equipment such as a pneumatic cylinder and a hydraulic cylinder, which can apply pressure from top to bottom, and use the pressure to press down the valve seat located inside the valve body, so that the valve seat moves to the expected installation position. An annular groove for installing the valve seat is generally provided inside the valve body. When the valve seat is pressed down, the valve seat will deform to a certain extent due to its metal properties, and then be installed inside the annular groove. A matching sealing structure is also provided in the annular groove, so when 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, a valve core needs to be installed on the valve seat, and a valve stem needs to be installed on the valve core. The installation position of the pressing cylinder 1 on one side of the vertical plate 201 is above the longitudinal portion of the moving groove 202. The extended position of the output end of the pressing cylinder 1 is the processing station. The transported valve body is placed at this position. Pressing down the output end of the pressing cylinder 1 can accurately install the valve seat inside the valve body.

[0025] Specifically, a groove with a slope is provided on one side of the vertical plate 201, and blocks with slopes are connected to the upper and lower ends of the movable plate 203. The movable plate 203 moves on the front side of the vertical plate 201 through the matching slope blocks and the slope grooves. A movable groove 202 is provided on the vertical plate 201, and the movable groove 202 includes a transverse portion and a longitudinal portion, and the longitudinal portion is located at one end of the transverse portion, and the transverse portion and the longitudinal portion are arranged at ninety degrees, and the longitudinal portion faces downward.

[0026] In this embodiment, the groove and block with the slope can limit the movable plate 203, so that it can smoothly move horizontally in front of the vertical plate 201 without falling. The longitudinal part of the movable groove 202 is located on one side of the downward direction of the pressing cylinder 1. When the movable 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 does not affect each other. When the output end of the pressing cylinder 1 needs to be pressed down, the movable block 205 and the connecting rod 206 have left the longitudinal part, so it will not affect the downward pressure of the pressing cylinder 1.

[0027] Specifically, an inclined groove 204 is provided on the movable plate 203, and the inclined groove 204 is inclined downward. A movable block 205 is connected to the inside of the inclined groove 204, and the movable block 205 also penetrates the movable groove 202. The movable block 205 is located at one end of the connecting rod 206, and the movable block 205 moves inside the movable groove 202 and the inclined groove 204.

[0028] In this embodiment, the purpose of setting the transverse part and the longitudinal part in the movable groove 202 is to cooperate with the inclined groove 204, so that the movable block 205 can be pressed down after being moved horizontally, so that the clamped valve seat can be pressed down into the corresponding valve body. This process requires two power parts in general equipment, one for horizontal movement and the other for downward pressure, or only drives the valve seat to move horizontally, and the downward pressure is completed by the downward pressure cylinder 1. No matter which loading process is used, there are corresponding disadvantages. The two power parts will not only cause energy waste, but the installation position may also coincide with the position of the downward pressure cylinder 1. The equipment that only drives the valve seat to move horizontally is directly assembled by pressing the downward pressure cylinder 1, and the fault tolerance rate is If the valve seat is tilted or slightly incorrectly placed, it will be directly pressed down by the pressing cylinder 1, and the damage rate of the workpiece is high. The equipment of the device can adjust the valve seat in the valve body by pressing down 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, thereby improving the yield rate. In this embodiment, the length of the longitudinal portion of the movable groove 202 matches the position of the annular groove in the valve body, and the distance that the clamp 207 penetrates into the valve body is above the annular groove. In this embodiment, the clamp 207 can use an internal support clamping device to support and fix the valve seat from the inner side, which does not affect the placement of the valve seat into the valve body.

[0029] Specifically, one side of the movable plate 203 is connected to a first hinged rod 208 via a hinged seat, and one end of the first hinged rod 208 is hinged to a second hinged rod 209 , the second hinged rod 209 is installed on one side of the drive motor 210 , and the output end of the drive motor 210 is connected to a pulley group 302 .

[0030] In this embodiment, the first hinge rod 208 and the second hinge rod 209 are located on the front side of the vertical plate 201. When the second hinge rod 209 is rotated so that the first hinge rod 208 follows the rotation, it will not affect the falling valve seat. Because a stop shaft is provided between the mounting plate 301 and the receiving platform 314, the stop shaft is arranged in an arc shape on the outside of the receiving platform 314. The first hinge rod 208 rotates on one side of the stop shaft, and the falling valve seat will move inside the stop shaft of the arc structure. The valve seat falling on the receiving platform 314 will be The inner support clamp 207 clamps and can set the receiving table 314 to a two-step frustum structure, with the valve seat placed on the lower frustum and the valve seat located at the center of the upper frustum. However, the upper frustum does not penetrate the valve seat, but slightly protrudes from the lower frustum, which plays a limiting role without delaying the clamping of the clamp 207. On this basis, a group of slightly downward vertical protrusions can be set at the other end of the horizontal part of the movable groove 202 to meet the purpose of the clamp 207 clamping the valve seat located on the receiving table 314.

[0031] Specifically, the valve seat material distribution component 3 includes a mounting plate 301, and the mounting plate 301 is located above the vertical plate 201, an opening is set in the middle of the first hinge shaft 310, and the opening matches the size of the valve seat, the pulley group 302 includes two groups of pulleys and belts wound around the outside thereof, one group of pulleys is located on one side of the driving motor 210, and the other group of pulleys is located on one side of the mounting plate 301, a worm 303 is connected to one side of the pulley group 302, and a worm wheel 304 is meshed on one side of the worm 303, and the upper surface of the worm wheel 304 is connected to the upper surface of the worm wheel 304. A first gear 305 is connected to the side through an axis, and a first half gear 306 is arranged 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 arranged above the second gear 307, the second half gear 308 and the first half gear 306 have different directions, and the first half gear 306 and the second half gear 308 are both meshed with the rack 309, a material receiving table 314 is arranged below the first hinge shaft 310, and a retaining shaft is arranged between the material receiving table 314 and the mounting plate 301.

[0032] In this embodiment, the driving motor 210 is a servo motor, which drives the pulley set 302 to rotate while also driving the second hinged rod 209 to rotate. The shaft extending from the middle of one set of pulleys in the pulley set 302 is connected to the second hinged rod 209. The driving motor 210 rotates in one direction, and the movable plate 203 is driven to move back and forth because of the second hinged rod 209 and the first hinged rod 208. The rack 309 in the valve seat dividing assembly 3 is driven to move back and forth by two sets of half gears in different directions, without the need for a motor. The rotation direction is adjusted repeatedly, thereby extending the service life of the motor. When the pulley set 302 drives the worm 303 to rotate, and the worm 303 drives the worm wheel 304 to rotate, the transmission between the worm 303 and the worm wheel 304 also plays a role in preventing reversal. The worm 303, the worm wheel 304, the first gear 305, and the second gear 307 are all arranged inside the mounting plate 301. A groove is opened on the mounting plate 301, and the first half gear 306 and the second half gear 308 extend from the groove and mesh with the rack 309.

[0033] Specifically, the rack 309 includes a rack portion and a rotating shaft portion, and the rack portion and the rotating shaft portion are hinged, 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, the number of hinged blocks 311 is four groups, and the hinged blocks 311 include a first circular arc portion 3111, a second circular arc portion 3112 and an inclined baffle 3113, the first circular arc portion 3111, the second circular arc portion 3112 and the inclined baffle 3113 are integrally formed, and the first circular arc portion 3111 and the second circular arc portion 3112 are both provided with a hinge seat, and are connected to the first hinge shaft 310 and the second hinge shaft 313 through the hinge seat, the inclined baffle 3113 is in contact with the valve seat, and the first circular arc portion 3111, the second circular arc portion 3112 and the inclined baffle 3113 are in a "Y" shape.

[0034] In this embodiment, the moving trajectory of the rack part in the rack 309 is a straight line, but the moving trajectory of the rotating shaft part and the first hinge shaft 310 is not necessarily a straight line. The position for installing the four sets of hinged blocks 311 has been positioned, so the power of the rack 309 only needs to make the four sets of hinged blocks 311 rotate at a certain angle. The position where the four sets of hinged blocks 311 are positioned on the mounting plate 301 is where the axis is installed in the middle of the hinged block 311, and the hinged block 311 and the hinged block 312 rotate around the axis as a whole.

[0035] Specifically, there are four groups of hinged baffles 312, and all of the four groups of hinged baffles 312 rotate along with the hinged block 311. There are three groups of second hinge shafts 313, and three groups of second hinge shafts 313 and one group of first hinge shafts 310 are arranged in a rectangular shape on the outside of the valve seat.

[0036] In this embodiment, the hinged baffle 312 is located above the hinged block 311, which is exactly the thickness of a valve seat, and there is an angle difference between the hinged baffle 312 and the inclined baffle 3113 in the vertical direction. Therefore, when the inclined baffle 3113 contacts the bottom valve seat, the hinged baffle 312 is located on the side of the upper valve seat. After the angle is rotated, the lower valve seat is not blocked and falls from the middle through hole of the mounting plate 301, and the hinged baffle 312 rotates and moves to the bottom end of the adjacent valve seat, blocking the valve seat from continuing to fall, and the timing of the valve seat falling meets the timing of the clamp 207 loading.

[0037] See also Figure 6-Figure 9 , a check valve seat assembly device, a transport platform 4 is installed on one side below the valve seat transport component 2, and a valve body transport component 5 is installed on the transport platform 4, the valve body transport component 5 includes a first clamping plate 501 and a second clamping plate 502, and the rear sides of the first clamping plate 501 and the second clamping plate 502 are both provided with a cross bar 504, and the cross bar 504 moves horizontally on the through block 505, the bottom end of the through block 505 is connected to a fixed block 509, and moves longitudinally on the fixed block 509, a rotating shaft 512 is rotated at the middle position of one side of the fixed block 509, and the through shaft 514 passing through the rotating shaft 512 moves in the rectangular groove 511 below, and the through shaft 514 passes through the cross groove block 508 above and drives the through block 505 to move.

[0038] In this embodiment, the valve bodies on the transport platform 4 are distributed at a certain distance interval. The first clamping plate 501 and the second clamping plate 502 move once along a rectangular trajectory, which will drive the clamped valve body to move once, so that the valve body located at one end of the transport platform 4 gradually moves until it moves to the processing station, that is, directly below the pressing cylinder 1. After waiting for the processing to be completed, the valve body will also be driven to move to the belt conveyor for normal unloading. The belt conveyor is flush with the transport platform 4. The frequency of the pressing down of the pressing cylinder 1 needs to be coordinated with the speed of movement of the valve body transport assembly 5. A controller is installed in the device. The controller directly controls the operation of electronic components in the device, such as the rotating motor 515 and the pressing cylinder 1. The movement speed between the rotating motor 515 and the pressing cylinder 1 is also adjusted by the controller.

[0039] Specifically, the first clamping plate 501 and the second clamping plate 502 are symmetrically arranged and have the same structure. A curved surface is arranged between the first clamping plate 501 and the second clamping plate 502, and the curved surface is in contact with the valve body. The rear sides of the first clamping plate 501 and the second clamping plate 502 are both connected to a connecting block 503, and a cross bar 504 is arranged on one side of the connecting block 503.

[0040] In this embodiment, a curved portion is provided between the first clamping plate 501 and the second clamping plate 502 in order to better clamp the curved valve body. The place on the valve body where the valve stem passes through is located in the middle and is not in direct contact with 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 action 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 to move by the pulley group located at the output end of the rotating motor 515.

[0041] 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 cross bar 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 groups of through blocks 505, and a transverse groove block 508 is connected between the two groups of through blocks 505.

[0042] 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 follow the rotation. 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 inner groove of the cross bar 504, so the movement of the through shaft 514 will also drive the cross bar 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 in a rectangular trajectory. The rectangular edge of the rectangular groove 511 is provided with an arc 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 are stationary.

[0043] Specifically, one side of the fixed block 509 is connected to a mounting block 510, and a rectangular groove 511 is provided inside the mounting block 510, a rotating shaft 512 is rotatably provided at the middle position 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 the through shaft 514 passes through the cross groove block 508 and extends to the bottom of the cross bar 504, a limiting groove is provided at the bottom end of the cross bar 504, a rotating motor 515 is installed at the bottom end of the mounting block 510, and the output end of the rotating motor 515 is connected to a pulley group, and the other end of the pulley group is located below the second clamping plate 502, a belt transport assembly is provided at one end of the transport platform 4, and a processing station is provided above the transport platform 4 and below the lower pressure cylinder 1.

[0044] In this embodiment, a rotating motor 515 is installed inside the transport platform 4, and a groove is opened on the transport platform 4 for the movement of parts such as the through shaft 514 and the through block 505, and the cross bar 504 and the connecting block 503 are located outside the groove.

[0045] When in use, it is necessary to connect an external power supply, which provides electrical energy for the device so that the device can operate normally. First, the valve seats stacked on the mounting plate 301 are divided by the valve seat dividing assembly 3, and the drive motor 210 is started, so that the drive motor 210 drives the pulley group 302 to rotate, and the pulley group 302 drives the worm 303 to rotate, thereby driving the worm wheel 304 meshing with it to rotate, and the worm wheel 304 drives the first gear 305 above to rotate. The first gear 305 drives the first half gear 306 to rotate while also driving the second gear 307 meshing with it to rotate. The second gear 307 will drive the second half gear 308 above to rotate, so that the first half gear 306 and the second half gear 308 rotate at the same time, but the first half gear 306 and the second half gear 308 have different directions, so they will not contact the rack 309 at the same time. 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 moving directions of the rack 309 will drive the change of the moving direction of the first hinge shaft 310. The movement of the first hinge shaft 310 will drive the front and rear two groups of hinge blocks 311 to rotate. Through the connection between the multiple groups of hinge blocks 311 and the hinge blocks 312, the hinge blocks 311 surrounding the outside of the valve seat are all rotated. When the four groups of inclined blocks 3113 are located at the bottom end of the valve seat, they will block the descent of the valve seat. At this time, the hinge blocks 312 are located on one side of the valve seat. When the hinge blocks 311 are rotated, all the inclined blocks 3113 rotate away from the bottom of the lowest valve seat, causing the valve seat at the lowest position to fall through the middle through hole of the mounting plate 301 and enter the top of the receiving platform 314. At this time, the hinge blocks 312 rotate to the bottom of the adjacent valve seat, so that the material discharge channel is blocked, and the valve seats are discharged one by one. When the pulley group 302 is rotating, the second hinge rod 209 on one side of the pulley group 302 is also driven to rotate, and the movable plate 203 is driven to move on the front side of the vertical plate 201 through the first hinge rod 208, so that the clamp 207 moves to the top of the receiving platform 314 and starts to clamp the valve seat. The continued rotation of the second hinge rod 209 will drive the movable plate 203 to move horizontally on one side of the vertical plate 201. When it moves to the longitudinal part of the movable groove 202, the movable block 205 will move downward under the cooperation of the longitudinal groove and the inclined groove 204, driving the connecting rod 206 and the clamp 207 and the clamped valve seat to move downward together, so that the valve seat moves down into the valve body located at the processing station on the transport platform 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 downward pressure cylinder 1 is pressed down at this time, pressing the valve seat located inside the valve body downward, so that it enters the installation position inside the valve body, and the assembly of the valve seat is completed. The assembled valve seat is driven by the valve body transport assembly 5 to be clamped and transported to the belt conveyor to complete the unloading. The process is that the started rotating motor 515 drives the rotating shaft 512 to rotate, and the rotation of the rotating shaft 512 drives the through-shaft 514 to rotate. The lower end of the through-shaft 514 is restricted inside the rectangular groove 511, so it can only move along a rectangular trajectory, and the upper end of the through-shaft 514 is located inside the transverse groove block 508, so when the through-shaft 514 moves, it will also drive the transverse groove block 508 to move, which will drive the through-block 505 to move on the fixed block 509, and the top end of the through-shaft 514 is restricted in the groove inside the cross bar 504. Therefore, when the through shaft 514 moves, it will also drive the cross bar 504 to move above the through block 505. The movement coordination of the two will make the first clamping plate 501 move along a rectangular moving trajectory, so that the two sets of opposite first clamping plates 501 and second clamping plates 502 move together to the middle to clamp the valve body, and then drive the clamped valve body to move, gradually approaching the direction of the lower pressure cylinder 1, and then the first clamping plate 501 and the second clamping plate 502 retreat to release the clamped valve body, and then move to the original position, and repeat this step to transport the valve bodies arranged in order 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.
