Description
Technical Field
[0001] This utility model relates to the field of spraying devices, specifically a valve seat spraying device. Background Technology
[0002] The valve seat, also known as the valve body seat, is a key component inside a high-pressure valve. It is a detachable surface component inside the high-pressure valve, mainly used to support the valve core in the fully closed position and to form a sealing pair together with the valve core.
[0003] In some highly corrosive media, the valve seat of a high-pressure valve is easily corroded and damaged. In order to improve the corrosion resistance of the valve seat, it is necessary to spray its surface. The spraying layer can be a coating with excellent corrosion resistance, such as epoxy resin, polyurethane, etc.
[0004] Existing valve seat spraying methods typically require the use of clamps to hold the valve seat in place. However, during production and observation, it was found that the clamps obstruct the valve seat surface. This necessitates adjusting or replacing the clamps after spraying to re-secure the valve seat and to touch up the obstructed areas.
[0005] Therefore, a valve seat spraying device is proposed to address the above problems. Utility Model Content
[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.
[0007] The technical solution adopted by this utility model to solve its technical problem is as follows: A valve seat spraying device of this utility model includes a worktable; a spraying component is provided on the top of the worktable; a motor is fixedly connected to the bottom of the worktable; a first gear is fixedly connected to the output end of the motor; the first gear and the worktable are rotatably connected; multiple second gears are rotatably connected to the bottom of the worktable; the second gears and the first gears are meshed; a first upright is bolted to the top of the second gear; a second upright is bolted to the top of the second gear; the first upright and the second upright are eccentrically set with different eccentric distances; multiple sliding grooves are opened on the surface of the worktable; the first upright and the sliding groove are slidably connected; the second upright and the sliding groove are also slidably connected; the first gear and the second gear can control the first upright and the second upright to be close to or away from the valve seat, realizing the device's flexible clamping of the valve seat and simplifying the operation steps of adjusting the clamp when the valve seat is obstructed during clamping.
[0008] Preferably, the second gear has multiple fixing holes on its surface; the fixing holes are correspondingly provided with the first and second uprights; by setting the fixing holes, the positions of the first and second uprights can be changed, allowing the device to fix and spray valve seats of various sizes, thus improving the flexibility of the device in fixing and spraying valve seats of different sizes.
[0009] Preferably, a screw is rotatably connected to the top of the workbench; a circular plate is fixedly connected to the top of the screw; a top plate is threadedly connected to the middle of the screw; multiple telescopic rods are fixedly connected to the bottom of the top plate; the telescopic rods and the workbench are both fixedly connected; when the valve seat is placed on the surface of the workbench, it can pass through the screw and be placed on the surface of the top plate. When it is necessary to flip the valve seat, the operator can rotate the screw to move the valve seat away from the workbench. At this time, the valve seat is in a suspended state, which improves the convenience of removing the valve seat from the surface of the workbench.
[0010] Preferably, the top plate has multiple positioning holes on its surface; a sliding plate is slidably connected to the middle of the top plate; multiple elastic plates are fixed to the top of the sliding plate; the elastic plates and positioning holes are correspondingly arranged; when the top plate needs to support valve seats of different sizes, the operator can pull the sliding plate to make it slide along the top plate. The sliding plate will move with the elastic plates. When the elastic plates move, they will contact the positioning holes and bend under the action of elastic force. At this time, the elastic plates will fill the interior of the positioning holes, and the sliding plate will be fixed under the friction between the elastic plates and the positioning holes. When the sliding plate needs to continue to slide, the operator needs to use force to make the elastic plates disengage from the positioning holes, thereby extending the length of the top plate and enabling the device to support valve seats of different sizes.
[0011] Preferably, friction pads are symmetrically fixed to the inner sidewall of the positioning hole; the friction pads are located at the top of the skateboard; when the elastic sheet is inserted into the positioning hole under the action of elastic force, the elastic sheet will come into contact with the friction pad. Because the friction coefficient of the friction pad surface is large, the friction between the elastic sheet and the positioning hole will also increase, thereby increasing the friction on the skateboard and improving the stability of the skateboard when it is fixed.
[0012] Preferably, the circular plate has multiple grooves in the middle; the grooves are arranged in a circumferential array; when the operator rotates the circular plate, the contact area between the operator and the circular plate increases because the circular plate has multiple grooves on its surface, thereby increasing the contact area when rotating the circular plate and improving the convenience of rotating the circular plate.
[0013] The advantages of this utility model are:
[0014] 1. The valve seat spraying device of this utility model can control the first and second uprights to be close to or away from the valve seat through the first gear and the second gear, so as to realize the flexible clamping of the valve seat by the device and reduce the impact of the valve seat being blocked during clamping on the spraying process.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.
[0024] Specific implementation examples are given below.
[0025] Please see Figures 1 to 5As shown in the figure, a valve seat spraying device according to an embodiment of the present invention includes a workbench 1; a spraying assembly 12 is provided on the top of the workbench 1; a motor 13 is fixedly connected to the bottom of the workbench 1; a first gear 14 is fixedly connected to the output end of the motor 13; the first gear 14 and the workbench 1 are rotatably connected; a plurality of second gears 15 are rotatably connected to the bottom of the workbench 1; the second gears 15 and the first gears 14 are meshed; a first upright 16 is bolted to the top of the second gear 15; a second upright 17 is bolted to the top of the second gear 15; the first upright 16 and the second upright 17 are eccentrically arranged with different eccentric distances; a plurality of sliding grooves 18 are formed on the surface of the workbench 1; the first upright 16 and the sliding grooves 18 are slidably connected; the second upright 17 and the sliding grooves 18 are also slidably connected; during operation, the valve seat is placed on the top of the workbench 1 and between the first upright 16 and the second upright 17, and then... The start motor 13 causes the first gear 14 to rotate. When the first gear 14 rotates, it meshes with the second gear 15, which in turn rotates the first upright 16 until it contacts the inner wall of the valve seat. At this point, the valve seat is fixed. Then, the operator can spray the outer and inner walls of the valve seat using the spraying assembly 12. After spraying, the motor 13 and the valve seat can be flipped so that the first upright 16 moves away from the valve seat while the second upright 17 moves closer to the outer wall of the valve seat until the second upright 17 presses and fixes the outer wall of the valve seat. Then, the operator can use the spraying assembly 12 to spray the area of the inner wall of the valve seat covered by the first upright 16 and the back. Finally, the surface of the valve seat will be evenly sprayed. The first gear 14 and the second gear 15 can control the first upright 16 and the second upright 17 to be close to or away from the valve seat, realizing flexible clamping of the valve seat by the device and simplifying the operation steps of adjusting the clamp when the valve seat is covered during clamping.
[0026] Please see Figure 2 and Figure 3 As shown, the second gear 15 has multiple fixing holes 2 on its surface; the fixing holes 2 are correspondingly set with the first upright 16 and the second upright 17; when the device needs to spray different sized valve seats, the distance between the first upright 16 and the second upright 17 needs to be adjusted. The operator can unscrew the first upright 16 and the second upright 17 and install them in the remaining fixing holes 2, so that the device can adapt to the spraying work of valve seats of different sizes; by setting the fixing holes 2 and changing the position of the first upright 16 and the second upright 17, the device can fix and spray valve seats of various sizes, improving the flexibility of the device in fixing and spraying valve seats of different sizes.
[0027] Please see Figures 2 to 5As shown, a screw 3 is rotatably connected to the top of the workbench 1; a circular plate 32 is fixedly connected to the top of the screw 3; a top plate 33 is threadedly connected to the middle of the screw 3; multiple telescopic rods 34 are fixedly connected to the bottom of the top plate 33; the telescopic rods 34 and the workbench 1 are both fixedly connected; when the valve seat is placed on the surface of the workbench 1, it can be passed through the screw 3 and placed on the surface of the top plate 33. When it is necessary to flip the valve seat, the operator can rotate the screw 3 to make the valve seat move away from the workbench 1. At this time, the valve seat is in a suspended state, which improves the convenience of removing the valve seat from the surface of the workbench 1.
[0028] Please see Figure 4 and Figure 5 As shown, the top plate 33 has multiple positioning holes 43 on its surface; a sliding plate 4 is slidably connected to the middle of the top plate 33; multiple elastic plates 42 are fixed to the top of the sliding plate 4; the elastic plates 42 and the positioning holes 43 are correspondingly arranged; when the top plate 33 needs to support valve seats of different sizes, the operator can pull the sliding plate 4 to make the sliding plate 4 slide along the top plate 33. The sliding plate 4 will move along with the elastic plates 42. When the elastic plates 42 move, they will contact the positioning holes 43 and bend under the action of elastic force. At this time, the elastic plates 42 will fill the interior of the positioning holes 43, and the sliding plate 4 will also be fixed under the friction between the elastic plates 42 and the positioning holes 43. When the sliding plate 4 needs to continue to slide, the operator needs to use force to make the elastic plates 42 disengage from the positioning holes 43, thereby extending the length of the top plate 33 so that the device can support valve seats of different sizes.
[0029] Please see Figure 5 As shown, friction pads 5 are symmetrically fixed to the inner wall of the positioning hole 43; the friction pads 5 are located at the top of the slide plate 4; when the elastic sheet 42 is inserted into the positioning hole 43 under the action of elastic force, the elastic sheet 42 will come into contact with the friction pad 5. Because the friction coefficient of the friction pad 5 is large, the friction between the elastic sheet 42 and the positioning hole 43 will also increase, increasing the friction on the slide plate 4 and improving the stability of the slide plate 4 when it is fixed.
[0030] Please see Figure 4 As shown, the circular plate 32 has multiple grooves 6 in the middle; the grooves 6 are arranged in a circumferential array; when the operator rotates the circular plate 32, the contact area between the operator and the circular plate 32 increases because the circular plate 32 has multiple grooves 6 on its surface, thereby increasing the contact area when rotating the circular plate 32 and improving the convenience of rotating the circular plate 32.
[0031] Please see Figure 2 As shown, the inner wall of the slide groove 18 is an arc-shaped structure. Because the inner wall of the slide groove 18 is an arc-shaped structure, the friction will be reduced when the first upright 16 and the second upright 17 slide along the slide groove 18, thereby reducing the wear on the first upright 16 and the second upright 17 during movement.
[0032] Working principle: The valve seat is placed on top of the workbench 1, between the first upright 16 and the second upright 17. Then, the motor 13 is started, causing the first gear 14 to rotate. The rotation of the first gear 14, through meshing, causes the second gear 15 to rotate. The rotation of the second gear 15 drives the first upright 16 to rotate until it contacts the inner wall of the valve seat, at which point the valve seat is fixed. Then, the operator can spray the outer and inner walls of the valve seat using the spraying assembly 12. After spraying, the motor 13 and the valve seat can be flipped, causing the first upright 16 to move away from the valve seat while the second upright 17 moves closer to the outer wall of the valve seat until... The second upright 17 will press and fix the outer wall of the valve seat. Then, the operator can use the spraying assembly 12 to apply additional spray to the area covered by the first upright 16 and the back of the valve seat's inner wall. Finally, the valve seat surface will be evenly sprayed. When the device needs to spray valve seats of different sizes, the distance between the first upright 16 and the second upright 17 needs to be adjusted. The operator can unscrew the first upright 16 and the second upright 17 and install them in the remaining fixing holes 2, allowing the device to adapt to spraying valve seats of different sizes. When the valve seat is placed on the surface of the workbench 1, it can be passed through the screw 3 and placed on the surface of the top plate 33. When the valve seat is flipped, the operator can rotate screw 3 to move the valve seat away from the workbench 1, at which point the valve seat is suspended. When the top plate 33 needs to support valve seats of different sizes, the operator can pull the slide plate 4 to slide along the top plate 33. The slide plate 4 will move along with the elastic plate 42. When the elastic plate 42 moves, it will contact the positioning hole 43 and bend under the action of elastic force. At this time, the elastic plate 42 will fill the interior of the positioning hole 43, and the slide plate 4 will also be fixed by the friction between the elastic plate 42 and the positioning hole 43. When the slide plate 4 needs to continue to slide, the operator needs to exert force to make the elastic plate 42 disengage. The device extends the length of the top plate 33 by moving away from the positioning hole 43. When the elastic plate 42 is inserted into the positioning hole 43 under the action of elastic force, the elastic plate 42 will come into contact with the friction pad 5. Because the friction coefficient of the friction pad 5 is large, the friction between the elastic plate 42 and the positioning hole 43 will also increase. When the operator rotates the circular plate 32, the contact area between the operator and the circular plate 32 will increase because the circular plate 32 has multiple grooves 6 on its surface. The contact area when rotating the circular plate 32 will also increase. Because the inner wall of the slide groove 18 is an arc-shaped structure, the friction will be reduced when the first upright 16 and the second upright 17 slide along the slide groove 18.
[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
