Abstract
Description
Technical Field
[0001] This utility model relates to the field of valve body passivation technology, specifically to a valve body passivation processing device. Background Technology
[0002] The valve body is a major component of a valve. During its processing, manufacturing, and subsequent transportation and storage, its surface is easily contaminated. It may also develop an oxide layer due to contact with environmental factors such as air and moisture. To solve these problems, passivation treatment of the valve body is an essential and crucial step. Passivation treatment can generate a dense and stable passivation film on the surface of the valve body through a chemical reaction.
[0003] However, when passivating the valve body, directly placing the valve body in the passivation tank while the valve body is stationary results in insufficient and uneven exchange of substances between the passivation liquid and the valve body surface, affecting the passivation quality. Furthermore, in order to achieve a certain passivation effect, it is necessary to extend the immersion time of the valve body in the passivation tank, which reduces production efficiency. Therefore, we propose a new type of valve body passivation processing device. Utility Model Content

[0038] This utility model provides a technical solution:
[0039] Please see Figures 1-6The valve body passivation processing device includes a base plate 1, a passivation pool 2 fixedly connected to the upper end of the base plate 1, a mesh box 3 set inside the passivation pool 2, two mounting plates 4 fixedly connected to the upper end of the base plate 1, and sliding grooves 5 opened on opposite sides of the two mounting plates 4. Sliding plates 6 are slidably connected to the inner walls of the two sliding grooves 5, and a lifting plate 7 is fixedly connected between the two sliding plates 6. An adjustment mechanism 8 is set on the lifting plate 7. A second threaded rod 9 is rotatably connected between the inner walls on both sides of one of the sliding grooves 5. The second threaded rod 9 is threadedly connected to the corresponding sliding plate 6. A second motor 10 is installed on the upper end of one of the mounting plates 4. The second motor 10 is a servo motor. The end of the output shaft of the second motor 10 extends into the corresponding sliding groove 5 and is fixedly connected to the upper end of the second threaded rod 9. A guide rod 11 is fixedly connected between the inner walls on both sides of the other sliding groove 5. The guide rod 11 is slidably connected to the corresponding sliding plate 6. Through the cooperation of the sliding grooves 5, the sliding plates 6 and the guide rod 11, a stable guide and support are provided for the up and down movement of the lifting plate 7.
[0040] The adjustment mechanism 8 includes a reciprocating moving component 81 and a clamping component 82. The reciprocating moving component 81 allows the mesh cage 3 to reciprocate within the passivation pool 2, so that the valve body placed in the mesh cage 3 can come into more full and uniform contact with the passivation liquid, thereby improving the overall passivation effect. The clamping component 82 can firmly clamp the mesh cage 3, ensuring the smooth progress of the passivation process.
[0041] Furthermore, the reciprocating moving assembly 81 includes a moving groove 811 formed in the lifting plate 7. A movable moving plate 812 is provided in the moving groove 811. A fixing block 813 is fixedly connected to the lower end of the moving plate 812. The lower end of the fixing block 813 extends to the outside. A connecting plate 814 is fixedly connected to one side wall of the moving plate 812. The connecting plate 814 is elastically connected to the inner wall of the moving groove 811 through a spring 815. The elastic force of the spring 815 ensures that the moving plate 812 is always subjected to an elastic restoring force during the movement. When the moving plate 812 moves in one direction, the spring 815 is stretched or compressed, storing elastic potential energy. When the driving force changes direction, the spring 815 releases the elastic potential energy, assisting the moving plate 812 to move in the opposite direction, making the reciprocating motion smoother and more stable.
[0042] Furthermore, a rack 816 is slidably connected to the inner wall of the moving groove 811, a connecting block 817 is fixedly connected to one end of the rack 816, and the other end of the connecting block 817 is fixedly connected to the other side wall of the moving plate 812.
[0043] Furthermore, a first motor 818 is installed on the outer wall of the lifting plate 7. The first motor 818 is a servo motor. The output shaft of the first motor 818 extends into the moving groove 811 and is fixedly connected to a gear 819. The gear 819 is an incomplete gear. The gear 819 meshes with the rack 816. During the rotation of the gear 819, only some teeth mesh with the rack 816. When the toothed part of the gear 819 meshes with the rack 816, it drives the rack 816 to make linear motion, thereby causing the moving plate 812 to move. When the toothless part of the gear 819 rotates to a position opposite to the rack 816, the rack 816 loses its driving force and moves in the opposite direction under the elastic action of the spring 815, thereby realizing the reciprocating motion of the moving plate 812.
[0044] Furthermore, the clamping assembly 82 includes a fixing plate 821 fixedly connected to the lower end of the fixing block 813. The lower end of the fixing plate 821 has two rectangular grooves 822. The inner walls on both sides of the two rectangular grooves 822 are rotatably connected to first threaded rods 823. Both first threaded rods 823 are bidirectional threaded rods. The two threaded ends of the two first threaded rods 823 are threadedly connected to clamping plates 824. The multiple clamping plates 824 cooperate with the mesh box 3. The multiple clamping plates 824 can stably clamp the mesh box 3 from both sides to prevent it from shaking, shifting or even falling off, thus ensuring the stability of the valve body during the passivation process.
[0045] Furthermore, the opposite ends of the two first threaded rods 823 both penetrate the fixed plate 821 and extend to the outside. The opposite ends of the two first threaded rods 823 are fixedly connected to knobs 825. By rotating the knobs 825, the first threaded rods 823 are rotated, thereby adjusting the distance between the clamping plates 824 to accommodate net cages 3 of different sizes and specifications.
[0046] In practical use, the working principle of this utility model is as follows:
[0047] When the operator uses the device, when it is necessary to adjust the height of the mesh box 3 in the passivation tank 2, the second motor 10 can be started, causing the second threaded rod 9 to rotate, which in turn causes the corresponding sliding plate 6 to move. With the cooperation of the guide rod 11, the two sliding plates 6 will move up and down synchronously, driving the lifting plate 7 and the adjustment mechanism 8 installed on the lifting plate 7 and the mesh box 3 to move up and down together, thereby realizing the adjustment of the height position of the mesh box 3 in the passivation tank 2.
[0048] During passivation, the first motor 818 can be started, causing the gear 819 to rotate, which in turn causes the rack 816 meshing with it to move. The movement of the rack 816 can drive the moving plate 812 to move. When the moving plate 812 moves, it will stretch or compress the spring 815, allowing it to store elastic potential energy. When the toothless part of the gear 819 is opposite to the rack 816, the rack 816 will lose power. At this time, the spring 815 releases elastic potential energy, pushing the moving plate 812 to move in the opposite direction, thereby realizing the reciprocating motion of the moving plate 812. The fixed block 813 at the lower end of the moving plate 812 will move together with the moving plate 812, thereby driving the clamping assembly 82 and the mesh box 3 to reciprocate within the passivation pool 2, so that the valve body in the mesh box 3 can make more thorough and uniform contact with the passivation liquid, improving the passivation effect.
[0049] When it is necessary to fix the mesh box 3, turn the knob 825 to drive the first threaded rod 823 to rotate. As the first threaded rod 823 rotates, the two clamping plates 824 will move towards each other. The two clamping plates 824 gradually approach and clamp the mesh box 3, thereby fixing the position of the mesh box 3 and preventing the mesh box 3 from shaking, shifting or even falling off during the operation of the device. This ensures the stability of the valve body during the passivation process. When it is necessary to remove the mesh box 3, turn the knob 825 in the opposite direction so that the two clamping plates 824 move away from each other, releasing the clamp on the mesh box 3, and the mesh box 3 can be easily removed from the device.
[0050] In summary, by improving and optimizing its working principle, the valve body passivation processing device enables height adjustment and reciprocating movement of the valve body during passivation, effectively solving the problems of poor passivation film quality and low processing efficiency when the valve body is stationary, thereby improving the passivation effect and production efficiency of the valve body.
[0051] The above are merely specific embodiments of this utility model, but the technical features of this utility model are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on this utility model to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of this utility model.
