Description

Technical Field

[0001] The present invention relates to the technical field of globe valve processing, and particularly to a globe valve processing device. Background Technique

[0002] A globe valve, also known as a stop valve, is a commonly used type of valve. A globe valve typically consists of components such as a valve body, a valve cover, a valve stem, a valve core, and a valve seat. The valve body is the main body of the valve and is used to connect pipelines; the valve cover is connected to the valve body and serves to seal and support; the valve stem is used to transmit the operating force to control the opening and closing of the valve core; the valve core is a key component of the globe valve, usually in a disc shape or conical shape, and cooperates with the valve seat to achieve sealing; the valve seat is fixed on the valve body and fits tightly with the valve core to achieve the function of cutting off the medium.

[0003] In the structure of a globe valve, except for the integrally formed valve body, when the valve stem inside it is connected to the valve seat or the valve core, it often requires operations such as pipe shrinking or pipe expanding. Through such operations, the diameters of both ends of the valve stem pipe are adjusted to match the size of the valve seat, thus facilitating subsequent assembly work.

[0004] The prior art with the publication number CN109226545B provides a globe valve processing device. This globe valve processing device includes: a necking device for necking the pipe orifice on the globe valve; a marking device for marking the globe valve; a transfer manipulator disposed between the necking device and the marking device to grab the globe valve processed by the necking device and transfer the globe valve to the marking device for marking by the marking device. The globe valve processing device solves the problem of low processing efficiency of globe valves in the prior art.

[0005] In the above prior art, although the globe valve is necked and marked, it does not involve how to specifically perform necking. And the existing necking devices have relatively single functions and can only perform necking on the pipe part and cannot perform flaring. During the processing of metal pipes, if flaring is required, the already necked metal pipe often has to be placed in another flaring device, and this process is time-consuming and laborious. In addition, in the processing of necking or flaring by the existing devices, only the pressure plate is used to simply squeeze the pipeline, and there are often problems of uneven necking and flaring.

[0006] It can be seen that a globe valve processing device is needed to solve the problems mentioned in the above background technique, that is, the existing necking devices have relatively single functions and cannot simultaneously have the flaring function, and only use the pressure plate to simply squeeze the pipeline, often resulting in problems of uneven necking and flaring.

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 Figures 1-9 A stop valve processing device includes a shell 1, an expansion and contraction tube assembly 2 is installed inside the shell 1, a rotating assembly 4 is arranged at one end of an adjusting assembly 3, the expansion and contraction tube assembly 2 includes a plurality of extrusion plates 201, and a closing plate 202 is arranged on the inner side of one end of the extrusion plate 201, and an expansion plate 203 is arranged on the outer side of the other end of the extrusion plate 201, and an inner tube 206 is connected to the inner side of the expansion plate 203 through a first hinge frame 204 and a second hinge frame 205, and one end of the inner tube 206 is arranged A screw tube 207 is provided, a moving block 208 is provided on the outside of the screw tube 207, and a third articulated frame 209 is hinged on the outside of the moving block 208, the third articulated frame 209 is penetrated by a through shaft 401, the other end of the through shaft 401 is connected to the inner tube 206, and a half gear 402 is connected to the outside of the through shaft 401, and a rotating disk 404 is provided below the half gear 402, the rotating disk 404 is provided with half teeth 405, and a worm 407 is connected below the rotating disk 404.

[0024] In this embodiment, the device makes a group of motors start to cause a certain displacement of multiple groups of pressing plates 201 simultaneously. The annular structure formed by the multiple groups of pressing plates 201 forms an expansion or contraction action. Then, by placing the valve pipe at the end of the pressing plate 201, the purpose of flaring or necking the pipe can be achieved. For example, by placing the port of the valve pipe inside the necking plate 202, when the pressing plate 201 presses inward, it will use multiple groups of necking plates 202 to press the pipe orifice together to make it smaller. The flaring action is to place one end of the valve pipe outside the flaring plate 203, and the action of the pressing plate 201 drives the flaring plate 203 to expand outward, thereby expanding the end of the valve pipe. The necking and flaring actions can only be performed on metal pipes because metal has a certain deformability. A metal pipe suitable for the size of this device can be selected for processing. In this device, a support device can be added outside the installation bin, and at the same time, a support device is connected to the tail of the inner pipe 206 through a bearing. The support device is connected to it through a clamp. When installing the valve pipe, the clamp is disconnected, and the entire device is fixed by relying on the support device at the other end.

[0025] Specifically, multiple groups of pressing plates 201 are all arc-shaped structures, and multiple groups of pressing plates 201 form a circular ring structure. Both the first hinge frame 204 and the second hinge frame 205 include a hinge shaft and a connecting ring. The connecting ring is fixed to the outside of the inner pipe 206, and the hinge shafts are evenly hinged to the outside of the connecting ring. The other ends of the hinge shafts are hinged to the inside of the pressing plate 201.

[0026] In this embodiment, the pressing plates 201, the necking plates 202, and the flaring plates 203 are all made of high-strength metal materials with high hardness and suitable for pressing metal to avoid deformation when pressing the valve pipe. The first hinge frame 204, the second hinge frame 205, and the third hinge frame 209 connected to the pressing plate 201, as well as the hinge seats connected to the hinge frames, are also made of metal with strong compressive capacity. The pressing plates 201 are provided in multiple groups, preferably eight groups or more. The more the number, the closer the formed arc is to a circle, and the better the flaring or necking effect.

[0027] Specifically, the lead screw pipe 207 rotates on one side of the inner pipe 206, and the inside of the lead screw pipe 207 is hollow. The lead screw pipe 207 and the through shaft 401 are connected through a bearing. The inside of the moving block 208 is provided with a threaded hole matching the lead screw pipe 207, and the moving block 208 moves outside the lead screw pipe 207. Both ends of the third hinge frame 209 are provided with hinge seats, and the end of the third hinge frame 209 away from the moving block 208 is hinged to the pressing plate 201.

[0028] In this embodiment, the rotating screw tube 207 drives the moving block 208 forward or backward, thereby driving the extrusion plate 201 to move. When the moving block 208 moves forward or backward, it will drive the third articulated frame 209 to tilt at different positions, thereby driving the extrusion plate 201 to move. The screw tube 207 rotates on one side of the inner tube 206 through a bearing, and the through shaft 401 penetrates the screw tube 207 and is directly connected to the inner tube 206. A bearing is provided between the screw tube 207 and the through shaft 401, so the rotation of the screw tube 207 will not affect the through shaft 401. The rings in the second articulated frame 205 and the first articulated frame 204 are fixed to the inner tube 206, so when the inner tube 206 rotates, it will drive the outer extrusion plate 201 to rotate, and the valve tube is clamped by the clamp 507 at this time, so the valve tube will not rotate, and the inner expansion and contraction mechanism will rotate.

[0029] Specifically, the half gear 402 includes a connecting ring and incomplete teeth, and the incomplete teeth are arranged on the connecting ring. The connecting ring is installed on the outside of the through shaft 401, and a protruding shaft 403 is arranged on the connecting ring. The incomplete teeth and the half teeth 405 are meshed with each other. A paddle plate 406 is arranged inside the rotating disk 404, and the paddle plate 406 is in contact with the protruding shaft 403.

[0030] In this embodiment, in addition to the incomplete teeth, a blank portion is also provided on the outer side of the connecting ring, and in addition to the half teeth 405, a blank portion is also provided on the rotating disk 404. When the blank portion on the half gear 402 contacts the blank portion on the rotating disk 404, the half gear 402 will not rotate, so the half gear 402 will only rotate intermittently, which is convenient for cooperating with the extrusion plate 201 to expand or shrink the mouth and then rotate after the action is finalized. If the half gear 402 needs to rotate all the time, that is, the expansion, shrinking and rotation actions are performed simultaneously, the teeth of the half gear 402 and the half teeth 405 can be set to complete teeth, so that the half gear 402 and the rotating disk 404 are always in a meshing state.

[0031] Specifically, a motor 408 is installed at the bottom end of the worm 407, and the rotating assembly 4 and the adjusting assembly 3 are both installed in the installation bin, and the installation bin is located on one side inside the extrusion plate 201, and a support column is connected to one side of the installation bin.

[0032] In this embodiment, the motor 408 is arranged on the outside of the installation bin. The motor 408 can be a servo motor. A controller is installed in the device, which can directly control the operation of electronic components in the device to achieve corresponding functions. The through shaft 401 passes through between the first large gear 305 and the second large gear 307, then passes through the rotating block 301 and the connecting tube 304, and then enters the interior of the screw tube 207, and finally connects with the inner tube 206.

[0033] Please refer to Figures 2-4 , a globe valve processing device, and a moving component 5 is installed at the top end of the outer shell 1.

[0034] In this embodiment, the mounting shell 501 is installed at the top end of the outer shell 1, and the fixture 507 is located at the end of the extrusion plate 201, facilitating the clamping of the valve pipe. After clamping the valve pipe with the fixture 507, the valve pipe and the fixture 507 are flipped together by displacement and gears. Otherwise, the transportation path will be blocked. Rotation will cause the fixture 507 and the valve pipe to be above the mounting shell 501, and the transportation path will not be blocked. When reaching the other end of the mounting shell 501, continue to flip, causing the valve pipe to flip 180 degrees, aligning the pipe orifice at the other end with one end of the extrusion plate 201, facilitating the flaring or necking operation on the other end of the valve pipe.

[0035] Specifically, the moving component 5 includes a displacement block 504 that reciprocates, and a pinion 505 is arranged on one side of the displacement block 504. The pinion 505 is connected to a fixture 507 through an extension arm 506, and a rack 502 meshing with the pinion 505 is arranged below the pinion 505.

[0036] In this embodiment, a motor is installed at one end of the lead screw 503, which can be a forward and reverse motor, and is controlled and driven by a controller installed in the device. Starting the motor will drive the displacement block 504 to move. The movement of the displacement block 504 will drive the pinion 505 to move. During the movement of the pinion 505, it contacts the rack 502 and meshes, so it will flip as it continues to move, thereby driving the extension arm 506 and the fixture 507 to flip together.

[0037] Specifically, the moving component 5 includes a mounting shell 501, and racks 502 are arranged at both ends of the outer side of the mounting shell 501. A lead screw 503 is arranged inside the mounting shell 501, and a displacement block 504 matching the lead screw 503 is arranged on the outer side of the lead screw 503. A through shaft is arranged between the displacement block 504 and the pinion 505, and the through shaft penetrates through the mounting shell 501 and extends to its outer side. The extension arm 506 is located on the outer side of the through shaft. A mechanism to prevent reverse rotation can be arranged at the connection between the through shaft between the displacement block 504 and the pinion 505 and the displacement block 504 to avoid reverse rotation after clamping and rotation. Also, the friction between the extension arm 506 and the through shaft can be increased so that the extension arm 506 can only rotate when the pinion 505 contacts the rack 502 and cannot rotate due to the gravity of the valve pipe.

[0038] In this embodiment, on the outer side of the outer shell 1, a set of conveyor belts can be installed at the middle position of the end of the extrusion plate 201. If the valve pipe only needs to be processed at one end, the clamping can be released at the middle position of the installation shell 501, and the valve pipe can be dropped onto the conveyor belt to complete the processing. The position of the rack 502 can be set at the protruding edge of the installation shell 501 to facilitate the release of the valve pipe clamped by the fixture 507 so that it can normally drop onto the belt conveyor.

[0039] Please refer to Figures 5-12 , a stop valve processing device, and an adjustment component 3 is installed at one end of the expansion and contraction pipe component 2.

[0040] In this embodiment, the setting of the adjustment component 3 can not only make the lead screw pipe 207 rotate forward and backward independently, but also due to the special shape of the rotating block 301, the rotating block 301 will stay for a period of time after being toggled and rotated once. This period of time can be coordinated with the intermittent time of the rotating component 4, and the whole extrusion plate 201 can be rotated by using the staying time, so as to achieve a better coordination effect.

[0041] Specifically, the adjustment component 3 includes a rotating block 301, and a groove 3011 is opened inside the rotating block 301, and a recess 3012 is arranged on one side of the groove 3011. A forward toggle group 302 is arranged above the rotating block 301, and a reverse toggle group 303 is arranged below the rotating block 301. The forward toggle group 302 and the reverse toggle group 303 have the same structure. A connecting pipe 304 is connected to the front side of the rotating block 301, and the rotating block 301 is connected to the lead screw pipe 207 through the connecting pipe 304.

[0042] In this embodiment, when the rotating block 301 is toggled and rotated once, the second large gear 307 will complete one rotation, and the moving block 208 will complete one forward or backward movement. A vertical plate is arranged at the rear side of the rotating block 301, and the vertical plate is located inside the installation bin. The rotating block 301 rotates on one side of the vertical plate, and the forward toggle group 302 and the reverse toggle group 303 are also located on one side of the vertical plate. The first large gear 305, the transmission gear group 306 and the second large gear 307 are located on the other side of the vertical plate. A shaft is arranged between the first large gear 305 and the forward toggle group 302, and a shaft is arranged between the second large gear 307 and the reverse toggle group 303. The shaft penetrates through the vertical plate and rotates inside it. The transmission gear group 306 is arranged on the same side as the first large gear 305 and the second large gear 307, but the transmission gear group 306 is not located exactly in the middle of the first large gear 305 and the second large gear 307, but on one side, and the middle position is reserved for the penetration shaft 401, and the penetration shaft 401 penetrates through the vertical plate.

[0043] Specifically, the forward shifting group 302 includes a central axis 3021, an arc block 3022, an extended axis 3023 and a shifting block 3024, the central axis 3021 connects the arc block 3022 and the extended axis 3023, the shifting block 3024 is located at one end of the extended axis 3023, and the shifting block 3024 matches the groove 3011, and the arc block 3022 matches the recessed portion 3012.

[0044] In this embodiment, after the shift block 3024 in the forward shifting group 302 contacts the groove 3011, the rotation of the forward shifting group 302 will cause the shift block 3024 to shift the rotating block 301 to rotate as a whole. After rotating to a certain angle, the shift block 3024 moves away from the groove 3011, and the arc block 3022 contacts the recessed portion 3012. Since the arc block 3022 is convex and the recessed portion 3012 is recessed, it is just in contact and will not drive the rotating block 301 to rotate. The rotating block 301 shifted by the shift block 3024 rotates the opening of another group of grooves 3011 to a position close to the shift block of the reverse shifting group 303 below. When the shift block of the reverse shifting group 303 rotates, it will enter the interior of the groove 3011 and drive the rotating block 301 to reverse, repeating the rotation process of the forward shifting group 302.

[0045] Specifically, the rear side of the forward shifting group 302 is connected to the first large gear 305, and a transmission gear group 306 is meshed below the first large gear 305. The transmission gear group 306 includes two groups of small gears, and a second large gear 307 is meshed below the transmission gear group 306. The second large gear 307 is located on the rear side of the reverse shifting group 303, and a turbine 308 is provided on the rear side of the second large gear 307, and a worm 407 is meshed on one side of the turbine 308.

[0046] In this embodiment, the meshing of the turbine 308 and the worm 407 can prevent reverse rotation, thereby avoiding the second large gear 307, the rotating block 301 and the screw tube 207 from reversing under pressure, which can make the device operate better.

[0047] 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 tube that needs to be expanded or shrunk is clamped using the clamp 507, and then the motor 408 is started. The motor 408 drives the worm 407 to rotate, and the worm 407 drives the rotating disk 404 and the turbine 308 to rotate. The rotation of the turbine 308 drives the second large gear 307 to rotate, and the second large gear 307 drives the first large gear 305 to rotate through the meshing transmission gear set 306. At the same time, the second large gear 307 also drives the reverse dial set 303 on the front side to rotate, and the first large gear 305 drives the forward dial set 302 on the front side to rotate. Due to the existence of the transmission gear set 306, the directions of the first large gear 305 and the second large gear 307 are opposite, that is, the directions of the forward dial set 302 and the reverse dial set 303 are opposite. On the contrary, when the forward toggle group 302 rotates, the rotating block 301 will be driven to rotate through the toggle block 3024, and when the reverse toggle group 303 rotates, the rotating block 301 will be driven to rotate in the reverse direction through the toggle block on one side thereof, and the rotating block 301 will drive the screw tube 207 to rotate through the front connecting tube 304. When the screw tube 207 rotates forward, the moving block 208 on its outer side will move forward, and when the screw tube 207 rotates reversely, the moving block 208 on its outer side will move backward, and the movement of the moving block 208 will drive the inclination angle of the third articulated frame 209 to change, so that the extrusion plate 201 at one end of the third articulated frame 209 is displaced to a certain position, and the extrusion plates 201 of the multiple groups of circular arc structures expand and contract with each other, so that the closing plate 202 or the expanding plate 203 at the end is used to expand and shrink the valve tube; The rotation of the worm 407 will also drive the rotating disk 404 to rotate. When the toggle piece 406 rotates to the bottom of the half gear 402, the toggle piece 406 will contact the protruding shaft 403, thereby toggling the half gear 402 to rotate. At this time, the teeth of the rotating half gear 402 are in contact and mesh with the half teeth 405, so that the half gear 402 continues to rotate. The rotation of the half gear 402 will drive the through shaft 401 to rotate, and the through shaft 401 will drive the inner tube 206 to rotate. When the inner tube 206 rotates, it will drive the extrusion plate 201 to rotate, so as to cooperate with the expansion and contraction actions, so that the extrusion plate 201 rotates as a whole after the expansion and contraction are finalized, so that the expansion and contraction shapes are more uniform. After the flaring or necking action at one end of the valve tube is completed, the lead screw 503 is started to rotate, so that the displacement block 504 drives the fixture 507 and the valve tube to move. During the movement, the small gear 505 will contact and engage with the rack 502, thus rotating. The rotation of the small gear 505 will drive the fixture 507 and the valve tube to rotate together, which can make the valve tube better transported. When it is transported to the other end of the installation shell 501, it is rotated once more, so that the valve tube flips and descends. At this time, the pipe orifice facing the pressing plate 201 is swapped, which is convenient for processing the unprocessed pipe orifice.

The scope of the present application is defined by the appended claims and their equivalents.
