Description

Technical Field

[0001] This utility model relates to the field of valve maintenance technology, and in particular to a high-efficiency grinding device for valve sealing surfaces. Background Technology

[0002] Valves are control components in fluid transport systems, possessing functions such as shut-off, regulation, flow guidance, backflow prevention, pressure stabilization, flow diversion, and pressure relief. Valves used in fluid control systems range from the simplest shut-off valves to the various valves used in highly complex automated control systems, with a wide variety of types and specifications. Valves can be used to control the flow of various types of fluids, including air, water, steam, various corrosive media, slurry, oil, liquid metals, and radioactive media.

[0003] A search of existing Chinese patents for "valve grinding tools" (publication number CN219310912U) revealed that this device does not require highly skilled personnel and can achieve very high smoothness and sealing performance on valve sealing surfaces. It features a miniaturized and lightweight design, improving efficiency while significantly reducing the professional skills required of on-site personnel. However, during operation, the grinding surface of the grinding disc may shift at an angle, resulting in uneven grinding and affecting the efficiency of the grinding operation. Utility Model Content

[0004] Based on this, it is necessary to address the problem that angular displacement of the grinding surface of the grinding disc may occur, leading to uneven grinding results and affecting the efficiency of the grinding operation. The device provides a high-efficiency grinding device for valve sealing surfaces, comprising: a servo motor, the output shaft of which is fixedly connected to a rotating shaft, the end of the rotating shaft away from the grinding disc being connected to the grinding disc; a positioning mechanism, installed between the servo motor and the grinding disc, the positioning mechanism being disposed on the surface of the rotating shaft; wherein, the positioning mechanism includes a depth positioning component sleeved on the surface of the rotating shaft, a mounting plate fixedly connected to the surface of the depth positioning component near the servo motor, the servo motor being fixedly connected to one side of the mounting plate, and a valve port positioning component mounted on the surface of the depth positioning component near the grinding disc.

[0005] In one embodiment, the depth positioning component includes a sliding sleeve sleeved on the surface of the rotating shaft. A mounting plate is fixedly connected to the surface of the sliding sleeve sleeve near the servo motor. A sliding sleeve seat is slidably connected to the surface of the sliding sleeve sleeve. An inner cavity is opened inside the sliding sleeve seat. Two first threaded sleeves are embedded and installed on the surface of the sliding sleeve seat away from the sliding sleeve sleeve. Two abutting rubber blocks are slidably connected to the inner wall of the inner cavity.

[0006] In one embodiment, the valve port positioning assembly includes a connecting plate slidably connected to the surface of the sliding sleeve rod. The connecting plate is fixedly connected to one end of the sliding sleeve seat. A plurality of guide frames are fixedly connected to the surface of the connecting plate. A sliding block is slidably connected to the inner wall of the guide frame. A second threaded sleeve is fixedly connected to the inner wall of the sliding block. A second threaded rod is threadedly connected to the inner wall of the second threaded sleeve.

[0007] In one embodiment, the abutting rubber block is rotatably connected to a first threaded rod near the surface of the adjacent first threaded sleeve, and the first threaded rod is threadedly connected to the inner wall of the adjacent first threaded sleeve.

[0008] In one embodiment, the sliding sleeve has multiple transverse grooves on both its upper and lower flat surfaces, and these transverse grooves abut against the surfaces of adjacent contact rubber blocks. The interlocking texture on the surface of the contact rubber blocks abuts against the transverse grooves on the surface of the sliding sleeve, increasing the sliding friction between the sliding sleeve and the surface of the sliding sleeve, thus restricting the sliding of the sliding sleeve.

[0009] In one embodiment, the end of the second threaded rod away from the connecting plate extends to the outside of the guide frame, and the second threaded rod is rotatably connected to the surface of the connecting plate. The end of the second threaded rod outside the guide frame can be operated by turning a knob with an Allen wrench.

[0010] In one embodiment, a pin is fixedly connected to one side of the sliding block, extending through to the outside of the guide frame, and an abutment block is fixedly connected to the other side of the sliding block. The guide frame has graduated markings on its side, which, together with the pin, assist in achieving a good grinding effect from the grinding disc.

[0011] Beneficial effects

[0012] The aforementioned high-efficiency grinding device for valve sealing surfaces, through the engagement of the first threaded rod and the first threaded sleeve with the knob, causes the contact rubber block to slide on the inner wall of the inner cavity. The contact grooves on the surface of the contact rubber block abut against the transverse grooves on the surface of the sliding sleeve rod, increasing the sliding friction between the sliding sleeve seat and the surface of the sliding sleeve rod, restricting the sliding of the sliding sleeve seat, and achieving the effect of adjusting according to the grinding depth. This ensures uniform contact between the grinding disc and the valve grinding surface, and improves the work efficiency of the grinding operation.

[0013] By setting up a valve port positioning component, the second threaded rod of the knob, in conjunction with the second threaded sleeve, drives the sliding block to slide on the inner wall of the guide frame. This allows the three contact blocks to form a good contact positioning effect at the valve interface, reducing the shaking of the grinding disc during the grinding operation and ensuring the stability of the grinding process.

[0026] The following is combined Figures 1-4 This invention describes a high-efficiency grinding device for valve sealing surfaces.

[0027] In one embodiment, a high-efficiency grinding device for valve sealing surfaces includes: a servo motor 1, with a rotating shaft 11 fixedly connected to the output shaft of the servo motor 1, and the end of the rotating shaft 11 away from the grinding disk 2 connected to the grinding disk 2; a positioning mechanism 3, which is installed between the servo motor 1 and the grinding disk 2, and is disposed on the surface of the rotating shaft 11; wherein, the positioning mechanism 3 includes a depth positioning component 31 sleeved on the surface of the rotating shaft 11, a mounting disk 33 fixedly connected to the surface of the depth positioning component 31 near the servo motor 1, the servo motor 1 being fixedly connected to one side of the mounting disk 33, and a valve port positioning component 32 installed on the surface of the depth positioning component 31 near the grinding disk 2;

[0028] like Figure 1 , Figure 2 and Figure 3As shown, the depth positioning component 31 includes a sliding sleeve 311 sleeved on the surface of the rotating shaft 11. A mounting plate 33 is fixedly connected to the surface of the sliding sleeve 311 near the servo motor 1. A sliding sleeve seat 312 is slidably connected to the surface of the sliding sleeve 311. An inner cavity 313 is opened inside the sliding sleeve seat 312. Two first threaded sleeves 314 are embedded in the surface of the sliding sleeve seat 312 away from the sliding sleeve 311. Two abutting rubber blocks 315 are slidably connected to the inner wall of the inner cavity 313. A first threaded rod 317 is rotatably connected to the surface of the abutting rubber block 315 near the adjacent first threaded sleeve 314. The first threaded rod 317 is threadedly connected to the inner wall of the adjacent first threaded sleeve 314. Multiple transverse grooves 316 are opened on the upper and lower flat surfaces of the sliding sleeve 311. The transverse grooves 316 abut against the surface of the adjacent abutting rubber block 315.

[0029] In this embodiment, the grinding depth is adjusted according to the position of the valve's external interface. The sliding sleeve 312 moves on the surface of the sliding sleeve rod 311, causing the valve port positioning component 32 to move synchronously. This allows for grinding operations on valves with different grinding depths. The grinding disc 2, through the engagement of the first threaded rod 317 and the first threaded sleeve 314, causes the contact rubber block 315 to slide on the inner wall of the inner cavity 313. The engagement texture on the surface of the contact rubber block 315 abuts against the transverse groove 316 on the surface of the sliding sleeve rod 311, increasing the sliding friction between the sliding sleeve 312 and the surface of the sliding sleeve rod 311, thus limiting the sliding of the sliding sleeve 312 and achieving the effect of adjusting according to the grinding depth.

[0030] like Figure 1 , Figure 2 and Figure 4 As shown, the valve positioning assembly 32 includes a connecting plate 321 slidably connected to the surface of the sliding sleeve rod 311. The connecting plate 321 is fixedly connected to one end of the sliding sleeve seat 312. A plurality of guide frames 322 are fixedly connected to the surface of the connecting plate 321. A sliding block 323 is slidably connected to the inner wall of the guide frame 322. A second threaded sleeve 326 is fixedly connected to the inner wall of the sliding block 323. A second threaded rod 327 is threadedly connected to the inner wall of the second threaded sleeve 326. The end of the second threaded rod 327 away from the connecting plate 321 extends to the outside of the guide frame 322. The second threaded rod 327 is rotatably connected to the surface of the connecting plate 321. A pointer 324 is fixedly connected to one side of the sliding block 323 extending to the outside of the guide frame 322. An abutment block 325 is fixedly connected to the other side of the sliding block 323.

[0031] In this embodiment, the device is adjusted according to the width of different valve interfaces. By rotating the second threaded rod 327 of the knob in conjunction with the second threaded sleeve 326, the sliding block 323 slides on the inner wall of the guide frame 322. This allows the three abutting blocks 325 to form a good abutting and positioning effect at the valve interface, reducing the shaking of the grinding disc 2 during the grinding operation and ensuring the stability of the grinding. The guide frame 322 is provided with scale marks on the side, which, together with the pointer 324, can assist the grinding disc 2 to achieve a good grinding effect.

[0032] Working principle: The width of the valve interface is adjusted according to the required grinding depth, so that the sliding sleeve 312 moves on the surface of the sliding sleeve rod 311, which drives the valve port positioning component 32 to move synchronously. The first threaded rod 317 of the knob, in cooperation with the first threaded sleeve 314, slides the abutment block 315 on the inner wall of the inner cavity 313. The snap-fit ​​texture on the surface of the abutment block 315 abuts against the transverse groove 316 on the surface of the sliding sleeve rod 311, which increases the sliding friction between the sliding sleeve 312 and the surface of the sliding sleeve rod 311 and restricts the sliding of the sliding sleeve 312. The second threaded rod 327 of the knob, in cooperation with the second threaded sleeve 326, drives the sliding block 323 to slide on the inner wall of the guide frame 322. The combination of the three abutment blocks 325 forms a good abutment positioning effect at the valve interface, reducing the shaking of the grinding disc 2 during the grinding operation and ensuring the stability of the grinding.

[0033] It should be noted that the servo motor 1 mentioned above are all devices with relatively mature existing technology applications. The specific model can be selected according to actual needs. At the same time, the servo motor 1 can be powered by the built-in power supply or by the mains power. The specific power supply method is selected according to the situation and will not be elaborated here.

[0034] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0035] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
