Description

Technical Field

[0001] This application belongs to the technical field of control valve installation equipment, and particularly relates to a retaining ring installation device for control valves. Background Technology

[0002] The retaining ring is installed on the regulating valve for a limiting function. Generally, the retaining ring is embedded in the groove during installation.

[0003] A Chinese patent with publication number CN207131933U discloses a pressure regulating valve, including a valve body, a pressure regulating seat, a diaphragm assembly, a valve assembly, a pressure regulating column, and a piston assembly. The diaphragm assembly includes a diaphragm, a diaphragm pressing seat, and a diaphragm pressure plate. A pressing plate is provided between the diaphragm and the diaphragm pressing seat. The diaphragm pressing seat is connected to the pressure regulating column through a connecting structure. A guide component is provided between the diaphragm pressing seat and the pressure regulating column. A concave ring is provided on the side wall of a first cavity, and an annular retaining ring is provided inside the concave ring. An elastic element is provided inside the first cavity.

[0004] The aforementioned regulating valve requires the installation of a retaining ring in the inner wall of the cavity. The existing installation method is inconvenient due to the influence of the elastic element inside the cavity, and this problem needs to be improved. Summary of the Invention

[0005] The purpose of this application is to address the aforementioned technical problems by providing a retaining ring installation device for installing a retaining ring in a cavity, such that the retaining ring is embedded in the inner wall of the cavity, and the installation of the retaining ring is not affected by the elastic element.

[0006] This application provides a retaining ring mounting device for a control valve, comprising:

[0007] Fixture;

[0008] A feeding device for feeding retaining rings, the feeding device including a push block, the push block being provided with a feeding groove adapted to the retaining ring;

[0009] A clamping device for clamping the retaining ring located in the feeding trough;

[0010] A limiting device is placed on the clamping device, and the limiting device includes a limiting element and a telescopic mechanism;

[0011] A pusher is used to push out the retaining ring placed on the clamping device.

[0012] The regulating valve part requiring a retaining ring is clamped using a clamp. The retaining ring is placed in the push block. The retaining ring is automatically fed into the feeding trough by a feeding device or manually. The push block is driven by a cylinder on the feeding device to move to a position suitable for the clamping device, facilitating clamping. After the clamping device clamps the retaining ring, it opens the limiting device, and the feeding trough aligns with the limiting device. The radial compression of the retaining ring during clamping facilitates its entry into the cavity of the regulating valve part. Then, the cylinder drives the push block to reset, allowing the push block to continue feeding. The limiting device uses a telescopic mechanism to extend and retract. When the limiting device retracts, it facilitates the passage of the retaining ring; when the limiting device extends, it allows the retaining ring to pass through. The limiting component is placed on the lower side of the retaining ring. Before the clamping device is installed, the elastic component is placed in the cavity of the regulating valve part. When the clamping device is installed, the retaining ring extends into the cavity of the regulating valve part. The retaining ring and the elastic component abut against each other, and the retaining ring and the elastic component are placed on both sides of the limiting component to prevent the retaining ring from colliding and interfering with the elastic component during installation, which would prevent the retaining ring from being embedded in the inner wall of the cavity. The retaining ring is pushed out of the clamping device by the pushing component. Under the action of its own elastic properties, the retaining ring is embedded in the groove of the cavity. The pushing component cooperates with the limiting component to make the retaining ring cooperate with the groove, ensuring the success rate of the retaining ring installation. After the retaining ring is installed, the limiting component is retracted by the telescopic mechanism to facilitate the limiting device to pass through the retaining ring.

[0013] Furthermore, the clamping device includes:

[0014] Clamping seat;

[0015] Gripper;

[0016] Push the sleeve;

[0017] First cylinder;

[0018] The first cylinder is installed between the gripper seat and the push sleeve. The gripper is provided with a movable inclined surface and a T-shaped portion. The push sleeve is provided with a T-shaped groove that matches the T-shaped portion. The end of the gripper is provided with a sliding seat. The gripper seat is provided with a slide rail that matches the sliding seat. The gripper is provided with an extension that matches the retaining ring.

[0019] The gripper is driven by a cylinder, hydraulic cylinder, screw, or threaded structure of a threaded seat, enabling it to move along the direction of gravity. The push sleeve is driven by a first cylinder, allowing relative movement between the push sleeve and the gripper. The gripper and push sleeve are installed through a T-shaped part and a T-slot structure. The gripper and gripper are installed through a sliding seat and a slide rail structure. The gripper and push sleeve are engaged by a moving inclined surface. When the first cylinder drives the push sleeve to move away from the gripper, the gripper moves towards the center to clamp the retaining ring, and the retaining ring deforms and contracts radially. The extension of the gripper abuts against the outer circumferential surface of the retaining ring. A gap is provided between the extension and the limiting member, which is adapted to the thickness of the retaining ring. The retaining ring is released at this gap and embedded in the groove on the inner wall of the cavity.

[0020] Furthermore, the push block is provided with a gripping groove, which is evenly distributed around the axis of the feeding groove, and the gripping groove is adapted to the gripper.

[0021] The gripping groove is adapted to the gripper, allowing the extension of the gripper to extend into the gripping groove, enabling the gripper to quickly and stably grip the retaining ring.

[0022] Furthermore, the telescopic mechanism includes:

[0023] Drive motor;

[0024] The rotating rod is mounted on the drive motor;

[0025] The limiting seat is installed and connected to the clamping seat;

[0026] The sleeve connects the limiting seat and the clamping seat and is sleeved on the outside of the rotating rod;

[0027] A hinged plate is mounted on a rotating rod, and the hinged plate is hinged to a limiting member;

[0028] The limiting member is hinged to the limiting seat.

[0029] The rotating rod is driven by a drive motor, and the hinge plate is mounted on the rotating rod and rotates simultaneously. The limiting seat is installed and connected to the clamping seat through a sleeve. When the rotating rod rotates, the limiting component moves, thus extending or retracting on the limiting device. The diameter of the limiting seat is smaller than the inner diameter of the retaining ring, which allows the limiting seat to pass through the retaining ring. The sleeve ensures the stable rotation of the rotating rod. The limiting component is arc-shaped, which facilitates the retraction of the limiting component. The connection between the limiting component and the hinge plate is a sliding hinge structure.

[0030] Furthermore, a shrinkage groove is provided around the periphery of the limiting seat, and the limiting member is installed in the shrinkage groove.

[0031] The limiting component is placed in the shrinkage groove. When the limiting component shrinks, it is completely placed in the shrinkage groove, ensuring the stable passage of the limiting component through the retaining ring.

[0032] Furthermore, the actuating element includes:

[0033] The locking mechanism is located on the sleeve;

[0034] A compression spring is placed between the pushing element and the locking mechanism;

[0035] A locking buckle is placed on the pusher and is adapted to the locking mechanism.

[0036] The pusher is movably mounted on the sleeve.

[0037] When the clamping device moves under the action of the first cylinder, the jaws clamp the retaining ring and at the same time, they act on the compression spring, causing the compression spring to compress. The spring then pushes the retaining ring against the pusher, causing the retaining ring to move and lock the locking buckle with the locking mechanism. When the retaining ring needs to be pushed out, it separates from the locking buckle through the locking mechanism. The pusher then pops out under the action of the compression spring and acts on the retaining ring clamped by the jaws, thereby separating the retaining ring from the jaws.

[0038] Furthermore, the locking mechanism includes:

[0039] Mounting plate, installed on the sleeve;

[0040] The movable buckle is hinged to the mounting plate.

[0041] The permanent magnet is installed on the movable buckle;

[0042] An electromagnet, mounted on a mounting plate and adapted to a permanent magnet;

[0043] The rotating component is provided with a toggle part, which acts on the movable buckle.

[0044] The locking mechanism uses a movable buckle to engage the locking buckle. The rotating part can be rotated by a rotating rod. When the rotating part rotates, it acts on the movable buckle, causing the movable buckle to rotate. When it is necessary for the movable buckle to engage with the locking buckle, the electromagnet is adjusted so that the electromagnet and the permanent magnet attract each other. When the rotating part rotates, the electromagnet and the permanent magnet are attracted to each other, thus achieving the engagement of the movable buckle and the locking buckle. When it is necessary for the pushing part to push out the retaining ring, the electromagnet is adjusted so that the electromagnet and the permanent magnet repel each other, thereby achieving the separation of the movable buckle and the locking buckle.

[0045] Furthermore, the locking mechanism also includes:

[0046] The incomplete toothed section is connected to the rotating rod;

[0047] Transmission gears, adapted to incomplete tooth sections;

[0048] The ratchet portion is located on the inner side of the rotating part;

[0049] The pawls are provided in several units and are evenly distributed around the axis of the transmission gear;

[0050] Return spring;

[0051] The transmission gear is provided with a mounting base, the pawl is hinged to the mounting base, and the return spring is placed between the pawl and the mounting base.

[0052] The retraction of the limiting component requires the rotating rod to repeatedly rotate in both directions. The rotation of the rotating rod causes the incomplete toothed part to rotate, which in turn engages with the transmission gear, causing the transmission gear to rotate. When the rotating rod rotates and extends the limiting component, the pawl rotates and acts on the ratchet toothed part, thereby enabling the rotating component to rotate. When the rotating rod rotates and retracts the limiting component, the return spring prevents the pawl from driving the rotating component to rotate. This ensures that when the retaining ring is clamped, the extension of the limiting component locks the pushing component simultaneously, facilitating the subsequent ejection of the retaining ring. When the limiting component retracts, it does not affect the state of the movable buckle, ensuring stable locking of the pushing component and preventing collisions between the movable buckle and the locking buckle.

[0053] The beneficial effects of this application are:

[0054] 1. When the clamping device clamps, the radial compression of the retaining ring facilitates its entry into the cavity of the regulating valve part. Then, the cylinder drives the push block to reset, which facilitates the push block to continue feeding. The limiting device can extend and retract through the telescopic mechanism. When the limiting part retracts, it facilitates the limiting device to pass through the retaining ring. When the limiting part extends, it facilitates the limiting device to be placed on the lower side of the retaining ring.

[0055] 2. When installing the clamping device, the retaining ring extends into the cavity of the regulating valve part. It abuts against the elastic element through the limiting element, and the retaining ring and elastic element are placed on both sides of the limiting element to prevent the retaining ring from colliding and interfering with the elastic element during installation, which would prevent the retaining ring from being embedded in the inner wall of the cavity.

[0056] 3. The retaining ring is pushed out of the clamping device by the pushing component. Under the action of its own elasticity, the retaining ring is embedded in the groove of the cavity. The pushing component and the limiting component cooperate to make the retaining ring fit into the groove, ensuring the success rate of the retaining ring installation.

[0057] 4. The retraction of the limiting component requires the rotating rod to repeatedly rotate in both directions. The rotation of the rotating rod causes the incomplete toothed part to rotate, which engages with the transmission gear, thereby causing the transmission gear to rotate. When the rotating rod rotates and causes the limiting component to extend, the pawl rotates and acts on the ratchet toothed part, thereby realizing the rotation of the rotating component. When the rotating rod rotates and causes the limiting component to retract, the return spring prevents the pawl from driving the rotating component to rotate. This ensures that when the retaining ring is clamped, the extending limiting component locks the pushing component at the same time, facilitating the subsequent ejection of the retaining ring.

Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0068] The portable server provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0069] Example 1:

[0070] like Figure 1 , Figure 2 , Figure 7 As shown, this application embodiment provides a retaining ring mounting device for a regulating valve, comprising:

[0071] Fixture 100;

[0072] The feeding device 200 is used for feeding the retaining ring. The feeding device 200 includes a push block 210, which is provided with a feeding groove 211 adapted to the retaining ring.

[0073] The clamping device 300 clamps the retaining ring located in the feeding groove 211;

[0074] A limiting device 400 is placed on the clamping device 300. The limiting device 400 includes a limiting member 410 and a telescopic mechanism 420.

[0075] Pusher 500 is used to push out the retaining ring placed on the clamping device 300.

[0076] The regulating valve part requiring the installation of a retaining ring is clamped by the clamp 100. The retaining ring is placed in the push block 210. The retaining ring is automatically fed into the feeding groove 211 by the feeding device 200 or manually. The push block 210 is driven by the cylinder on the feeding device 200 to move to the position adapted to the clamping device 300 for easy clamping. After the clamping device 300 clamps the retaining ring, it opens the limiting device 400, and the feeding groove 211 is adapted to the limiting device 400. The radial compression of the retaining ring during clamping facilitates its entry into the cavity of the regulating valve part. Then, the cylinder drives the push block 210 to reset so that the push block 210 can continue to feed. The limiting device 400 allows the limiting member 410 to extend and retract through the telescopic mechanism 420. When the limiting member 410 retracts, it facilitates the passage of the limiting device 400. The retaining ring facilitates the movement of the limiting member 410 when it extends. The limiting member 410 is placed on the lower side of the retaining ring. Before the clamping device 300 is installed, the elastic member is placed in the cavity of the regulating valve part. When the clamping device 300 is installed, the retaining ring extends into the cavity of the regulating valve part. The limiting member 410 abuts against the elastic member, and the retaining ring and the elastic member are placed on both sides of the limiting member 410 to prevent the retaining ring from colliding and interfering with the elastic member during installation, which would prevent the retaining ring from being embedded in the inner wall of the cavity. The pushing member 500 pushes the retaining ring out of the clamping device 300. Under the action of its own elastic properties, the retaining ring is embedded in the groove of the cavity. The pushing member 500 cooperates with the limiting member 410 to make the retaining ring cooperate with the groove, ensuring the success rate of the retaining ring installation. After the retaining ring is installed, the telescopic mechanism 420 retracts the limiting member 410 to facilitate the passing of the limiting device 400 through the retaining ring.

[0077] Furthermore, the push block 210 is provided with a gripping groove 212, which is evenly distributed around the axis of the feeding groove 211, and the gripping groove 212 is adapted to the gripper 320.

[0078] The gripping groove 212 is adapted to the gripper 320, so that the extension 324 of the gripper 320 can extend into the gripping groove 212, enabling the gripper 320 to quickly and stably grip the retaining ring.

[0079] Example 2:

[0080] like Figure 2 As shown, this application embodiment provides a retaining ring mounting device for a regulating valve. In addition to the above-mentioned technical features, the clamping device 300 further includes:

[0081] Clamping seat 310;

[0082] Gripper 320;

[0083] Push-on 330;

[0084] First cylinder 340;

[0085] The first cylinder 340 is installed between the gripping seat 310 and the push sleeve 330. The gripper 320 is provided with a movable inclined surface 321, and the movable inclined surface 321 is provided with a T-shaped part 322. The push sleeve 330 is provided with a T-shaped groove 331 that matches the T-shaped part 322. The end of the gripper 320 is provided with a sliding seat 323. The gripping seat 310 is provided with a slide rail 311 that matches the sliding seat 323. The gripper 320 is provided with an extension 324 that matches the retaining ring.

[0086] The gripper 310 is driven by a cylinder, hydraulic cylinder, screw, or threaded structure of a threaded seat, enabling it to move along the direction of gravity. The push sleeve 330 is driven by a first cylinder 340, allowing relative movement between the push sleeve 330 and the gripper 310. The gripper 320 is mounted to the push sleeve 330 via a T-shaped part 322 and a T-slot 331. The gripper 320 is mounted to the gripper 310 via a sliding seat 323 and a slide rail 311. The 20 and the push sleeve 330 are engaged by the movable inclined surface 321. When the first cylinder 340 drives the push sleeve 330 to move away from the gripper 310, the gripper 320 moves towards the center to clamp the retaining ring and causes the retaining ring to deform and shrink radially. The extension 324 of the gripper 320 abuts against the outer peripheral surface of the retaining ring. A gap is provided between the extension 324 and the limiting member 410. This gap is adapted to the thickness of the retaining ring. The retaining ring is released at this gap and embedded in the groove of the inner wall of the cavity.

[0087] Example 3:

[0088] like Figure 2 , Figure 3 As shown, this application embodiment provides a retaining ring mounting device for a regulating valve. In addition to the above-mentioned technical features, the telescopic mechanism 420 further includes:

[0089] Drive motor 421;

[0090] Rotating rod 422 is mounted on drive motor 421;

[0091] The limiting seat 423 is installed and connected to the clamping seat 310;

[0092] Sleeve 424 is connected between limit seat 423 and clamping seat 310 and sleeved outside rotating rod 422;

[0093] A hinge plate 425 is mounted on a rotating rod 422, and the hinge plate 425 is hinged to a limiting member 410.

[0094] The limiting member 410 is hinged to the limiting seat 423.

[0095] The rotating rod 422 is driven to rotate by the drive motor 421. The hinge plate 425 is mounted on the rotating rod 422 and rotates simultaneously. The limiting seat 423 is installed and connected to the clamping seat 310 through the sleeve 424. When the rotating rod 422 rotates, the limiting member 410 moves and extends or retracts on the limiting device 400. The diameter of the limiting seat 423 is smaller than the inner diameter of the retaining ring, which allows the limiting seat 423 to pass through the retaining ring. The sleeve 424 ensures the stable rotation of the rotating rod 422. The limiting member 410 is arc-shaped, which facilitates the retraction of the limiting member 410. The connection between the limiting member 410 and the hinge plate 425 is a sliding hinge structure.

[0096] Furthermore, a shrinkage groove 426 is provided around the periphery of the limiting seat 423, and the limiting member 410 is installed in the shrinkage groove 426.

[0097] The limiting member 410 is placed in the shrinkage groove 426. When the limiting member 410 shrinks, it is completely placed in the shrinkage groove 426, ensuring that the limiting member 410 passes stably through the retaining ring.

[0098] Example 4:

[0099] like Figure 4 , Figure 5 , Figure 6 As shown, this application embodiment provides a retaining ring mounting device for a regulating valve. In addition to the above-mentioned technical features, the pushing member 500 further includes:

[0100] Locking mechanism 510 is located on sleeve 424;

[0101] The compression spring 520 is positioned between the pusher 500 and the locking mechanism 510;

[0102] A locking buckle 501 is placed on the pusher 500, and the locking buckle 501 is adapted to the locking mechanism 510;

[0103] The pusher 500 is movably mounted on the sleeve 424.

[0104] When the clamping device 300 moves under the action of the first cylinder 340, the gripper 320 clamps the retaining ring, and at the same time, it acts on the compression spring 520, causing the compression spring 520 to compress. The pusher 500 abuts against the retaining ring, pushing the retaining ring to move and locking the locking buckle 501 with the locking mechanism 510. When the retaining ring needs to be pushed out, the locking mechanism 510 separates from the locking buckle 501, causing the pusher 500 to pop out under the action of the compression spring 520 and act on the retaining ring clamped by the gripper 320, thereby realizing the separation of the retaining ring from the gripper 320.

[0105] Furthermore, the locking mechanism 510 includes:

[0106] Mounting plate 511 is installed on sleeve 424;

[0107] The movable buckle 512 is hinged to the mounting plate 511;

[0108] Permanent magnet 513 is mounted on movable buckle 512;

[0109] Electromagnet 514 is mounted on mounting plate 511 and is compatible with permanent magnet 513;

[0110] The rotating component 515 is provided with a toggle part 519, which acts on the movable buckle 512.

[0111] The locking mechanism 510 engages the locking buckle 501 via the movable buckle 512. The rotating part 515 can rotate via the rotating rod 422. When the rotating part 515 rotates, it acts on the movable buckle 512, causing the movable buckle 512 to rotate. When it is necessary for the movable buckle 512 to engage with the locking buckle 501, the electromagnet 514 is adjusted so that the electromagnet 514 and the permanent magnet 513 attract each other. When the rotating part 515 rotates, the electromagnet 514 and the permanent magnet 513 are attracted, thus achieving the engagement of the movable buckle 512 and the locking buckle 501. When it is necessary for the pushing part 500 to push out the retaining ring, the electromagnet 514 is adjusted so that the electromagnet 514 and the permanent magnet 513 repel each other, thereby achieving the separation of the movable buckle 512 and the locking buckle 501.

[0112] Furthermore, the locking mechanism 510 also includes:

[0113] The incomplete toothed part 516 is connected to the rotating rod 422;

[0114] The transmission gear 530 is adapted to the incomplete tooth section 516;

[0115] The ratchet portion 540 is located on the inner side of the rotating part 515;

[0116] The pawl 550 is provided in several parts and is evenly distributed around the axis of the transmission gear 530;

[0117] Return spring 560;

[0118] The transmission gear 530 is provided with a mounting base 531, the pawl 550 is hinged to the mounting base 531, and the return spring 560 is placed between the pawl 550 and the mounting base 531.

[0119] The retraction of the limiting member 410 requires the rotating rod 422 to repeatedly rotate in both directions. The rotation of the rotating rod 422 causes the incomplete tooth 516 to rotate, which engages with the transmission gear 530, thereby causing the transmission gear 530 to rotate. When the rotating rod 422 rotates and causes the limiting member 410 to extend, the pawl 550 rotates and acts on the ratchet 540, thereby realizing the rotation of the rotating member 515. When the rotating rod 422 rotates and causes the limiting member 410 to retract, the return spring 560 prevents the pawl 550 from driving the rotating member 515 to rotate. This ensures that when the retaining ring is clamped, the extending limiting member 410 locks the pushing member 500 at the same time, facilitating the subsequent ejection of the retaining ring. When the limiting member 410 retracts, it does not affect the state of the movable buckle 512, ensuring that the pushing member 500 can be stably locked in the future, preventing the movable buckle 512 from colliding with the locking buckle 501.
