Description

Technical Field

[0001] This utility model relates to the field of gate valve polishing, specifically a valve body polishing structure for gate valve production. Background Technology

[0002] A gate valve, also known as a stop valve, is a type of forced-seal valve. When the valve is closed, pressure must be applied to the valve disc to force a leak-proof seal. When the medium enters the valve from below the valve disc, the resistance that the operating force needs to overcome is the frictional force of the valve stem and packing, plus the thrust generated by the pressure of the medium. The force required to close the valve is greater than the force required to open it, so the valve stem diameter must be larger; otherwise, the valve stem may bend. According to the connection method, there are three types: flange connection, threaded connection, and welded connection.

[0003] The polishing structure of the valve body is a key step in the manufacturing process of gate valves. Its design directly affects the surface quality, sealing performance and service life of the valve body. However, traditional polishing equipment usually uses grinding stones or spherical abrasives. Since gate valves are irregularly shaped parts, it is difficult to easily polish the uneven surfaces and dead corners. In addition, traditional polishing equipment mainly relies on manual operation. The instability of manual operation leads to a further reduction in polishing efficiency, and workers are prone to operational errors when fatigued. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, traditional polishing equipment typically uses grinding stones or spherical abrasives. However, since the gate valve is an irregularly shaped part, it is difficult to easily polish the uneven surfaces and dead corners. This utility model proposes a valve body polishing structure for gate valve production.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a valve body polishing structure for the production of a stop valve, including a processing box, a sealing door rotatably connected to the processing box, a sand storage box fixedly connected to the bottom of the processing box, a support leg fixedly connected to the surface of the sand storage box, and a support mechanism provided in the inner cavity of the processing box.

[0006] The support mechanism includes a fixed plate, one side of which is fixedly connected to the inner wall of the processing box. A first ball seat is fixedly connected to one side of the fixed plate, and multiple first ball seats are provided. A telescopic rod is fixedly connected to the surface of each first ball seat. A second ball seat is fixedly connected to one end of each telescopic rod. A movable plate is fixedly connected to one side of the second ball seat. A first motor is fixedly installed on one side of the fixed plate. A cam is fixedly connected to the output end of the first motor. A transmission ring is fixedly connected to one side of the movable plate. The surface of the cam is in contact with the inner wall of the transmission ring. A clamping mechanism is provided on the other side of the movable plate.

[0007] Preferably, the clamping mechanism includes two support plates, one side of each support plate is fixedly connected to one side of the movable plate, and an electric push rod is rotatably connected to the inner cavity of the support plate. One end of the electric push rod is fixedly connected to a clamping plate.

[0008] Preferably, a second motor is fixedly installed on one side of the support plate, and the output end of the second motor is fixedly connected to one end of the electric push rod.

[0009] Preferably, a high-pressure pump is fixedly installed on one side of the processing box, the input end of the high-pressure pump is fixedly connected to a feed pipe, the output end of the high-pressure pump is fixedly connected to a spray pipe, and the surface of the spray pipe is fixedly connected to the inner wall of the processing box.

[0010] Preferably, the bottom of the sand storage box is fixedly connected to a connecting pipe, and one end of the connecting pipe is fixedly connected to one end of the nozzle.

[0011] Preferably, the inner wall of the processing box is fixedly connected to a partition, and the surface of the partition is provided with filter holes, the number of which is several.

[0012] Preferably, an air pump is fixedly installed on one side of the processing box, and a telescopic air pipe is fixedly connected to the output end of the air pump. The surface of the telescopic air pipe is disposed in the inner cavity of the processing box, and an air gun is fixedly connected to one end of the telescopic air pipe.

[0013] The advantages of this utility model are:

[0014] This invention uses quartz sand, corundum, and steel shot to clean and polish the surface of the gate valve. The support legs provide primary support. The polishing process can be completed within the cavity of the processing box. The sand storage box cavity is mainly used to store the sprayed material, and the processing box cavity and the sand storage box cavity are connected. The movable plate in the support mechanism provides primary support for the gate valve. The gate valve is fixed to the support mechanism as a whole by a clamping mechanism. The support mechanism is fixedly installed inside the processing box by a fixing plate. The protruding part of the cam fits against the inner wall of the transmission ring. When the first motor drives the cam to rotate, the cam protrudes... The drive ring in the part causes the movable plate to swing periodically. The first ball seat, the telescopic rod, and the second ball seat enable the movable plate to swing in all directions, improving the coverage of the sandblasting on the surface of the gate valve. With the adjustment of the telescopic rod's extension and retraction, it can actively adapt to the dynamic support requirements of the movable plate's swing. Thus, the sandblasting process ensures the polishing quality of irregularly shaped gate valves. Combined with the automatically swinging support mechanism, it improves polishing efficiency and solves the problem that traditional polishing equipment usually uses grinding stones or spherical abrasives, which makes it difficult to easily polish the uneven surfaces and dead corners of the gate valve due to its irregular shape.

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.

[0022] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0023] This application discloses a valve body polishing structure for manufacturing a stop valve. (Refer to...) Figures 1 to 4 A valve body polishing structure for the production of a stop valve includes a processing box 1, a sealing door 2 rotatably connected to the processing box 1, a sand storage box 3 fixedly connected to the bottom of the processing box 1, a support leg 4 fixedly connected to the surface of the sand storage box 3, and a support mechanism 5 provided in the inner cavity of the processing box 1.

[0024] The support mechanism 5 includes a fixed plate 501. One side of the fixed plate 501 is fixedly connected to the inner wall of the processing box 1. A first ball seat 502 is fixedly connected to one side of the fixed plate 501. Multiple first ball seats 502 are provided. A telescopic rod 503 is fixedly connected to the surface of each first ball seat 502. A second ball seat 504 is fixedly connected to one end of the telescopic rod 503. A movable plate 505 is fixedly connected to one side of the second ball seat 504. A first motor 506 is fixedly installed on one side of the fixed plate 501. A cam 507 is fixedly connected to the output end of the first motor 506. A transmission ring 508 is fixedly connected to one side of the movable plate 505. The surface of the cam 507 is in contact with the inner wall of the transmission ring 508. A clamping mechanism 6 is provided on the other side of the movable plate 505. The valve body polishing structure for the production of this gate valve uses quartz sand, corundum, steel shot, etc. to clean and polish the surface of the gate valve. The support leg 4 plays a major supporting role. The gate valve polishing process can be carried out in the cavity of the processing box 1. Completed, the cavity of the sand storage box 3 is mainly used to store the spraying material, and the cavity of the processing box 1 is connected to the cavity of the sand storage box 3. The movable plate 505 in the support mechanism 5 plays a major supporting role for the stop valve. The stop valve is fixed to the support mechanism 5 as a whole through the clamping mechanism 6. The support mechanism 5 is fixedly installed inside the processing box 1 through the fixing plate 501. The protrusion of the cam 507 is in contact with the inner wall of the transmission ring 508. When the first motor 506 drives the cam 507 to rotate, the protrusion of the cam 507 pushes the transmission ring 508 to make the movable plate 505 swing periodically. The first ball seat 502, the telescopic rod 503 and the second ball seat 504 realize the all-round swing of the movable plate 505, improve the coverage of the sandblasting on the surface of the stop valve. With the adjustment of the extension amount of the telescopic rod 503, it can actively adapt to the dynamic support requirements of the swing of the movable plate 505, thereby ensuring the polishing quality of the irregular stop valve through the sandblasting process, and improving the polishing efficiency with the automatically swinging support mechanism 5.

[0025] Reference Figure 4 The clamping mechanism 6 includes two support plates 601. One side of each support plate 601 is fixedly connected to one side of the movable plate 505. An electric push rod 602 is rotatably connected to the inner cavity of the support plate 601. One end of the electric push rod 602 is fixedly connected to a clamping plate 603. A second motor 604 is fixedly installed on one side of the support plate 601. The output end of the second motor 604 is fixedly connected to one end of the electric push rod 602. Through the clamping mechanism 6, the support plates 601 in the clamping mechanism 6 play the role of supporting and raising the stop valve. The electric push rods 602 on both sides can push the clamping plate 603 to clamp and fix the stop valve in the middle. The second motor 604 can drive a set of electric push rods 602 to rotate. While the electric push rods 602 rotate, they drive the stop valve to flip, thereby improving the processing efficiency of the stop valve.

[0026] Reference Figure 3A high-pressure pump 7 is fixedly installed on one side of the processing box 1. The input end of the high-pressure pump 7 is fixedly connected to the feed pipe 8, and the output end of the high-pressure pump 7 is fixedly connected to the nozzle 9. The surface of the nozzle 9 is fixedly connected to the inner wall of the processing box 1. The bottom of the sand storage box 3 is fixedly connected to the connecting pipe 10. One end of the connecting pipe 10 is fixedly connected to one end of the nozzle 9. Through the high-pressure pump 7, the connecting pipe 10 and the feed pipe 8, the high-pressure pump 7 is connected to the spray material in the sand storage box 3. During polishing, the spray material in the sand storage box 3 can be transported at high speed to the nozzle 9 through the high-pressure pump 7. The port of the nozzle 9 is located above the support mechanism 5. Therefore, the surface of the shut-off valve can be polished by spraying sand and high-speed spray material through the nozzle 9.

[0027] Reference Figure 3 A partition 11 is fixedly connected to the inner wall of the processing box 1. The surface of the partition 11 is provided with filter holes 12. The number of filter holes 12 is several. Through the partition 11, the filter holes 12 on the surface of the partition 11 can block the rust and dirt on the surface of the shut-off valve. The spray material can fall back into the sand storage box 3 through the filter holes 12, thereby completing the cyclic sandblasting.

[0028] Reference Figure 2 and Figure 3 An air pump 13 is fixedly installed on one side of the processing box 1. The output end of the air pump 13 is fixedly connected to a telescopic air pipe 14. The surface of the telescopic air pipe 14 is set in the inner cavity of the processing box 1. One end of the telescopic air pipe 14 is fixedly connected to an air gun 15. Through the air gun 15, the air pump 13 can supply air to the telescopic air pipe 14 and the air gun 15. The air gun 15 can remove the residual spray material on the support mechanism 5. While supplying air to the telescopic air pipe 14, the flexibility of the air gun 15 can be improved.

[0029] Working principle: Opening the sealing door 2 allows the shut-off valve to be processed to be placed on the movable plate 505. The electric push rods 602 on both sides can push the clamping plate 603 to clamp and fix the shut-off valve in the middle. The high-pressure pump 7 delivers the abrasive material in the sand storage box 3 to the spray pipe 9 at high speed. The port of the spray pipe 9 is located above the support mechanism 5, so the surface of the shut-off valve can be polished by high-speed abrasive spraying through the spray pipe 9. The protruding part of the cam 507 is in contact with the inner wall of the transmission ring 508. When the first motor 506 drives the cam 507 to rotate, the protruding part of the cam 507 pushes the transmission ring 508. The movable plate 505 is periodically oscillating. The first ball seat 502, the telescopic rod 503, and the second ball seat 504 enable the movable plate 505 to oscillate in all directions, improving the coverage of the sandblasting on the surface of the gate valve. With the adjustment of the telescopic rod 503, it can actively adapt to the dynamic support requirements of the oscillation of the movable plate 505. The second motor 604 can drive a set of electric push rods 602 to rotate. The rotation of the electric push rods 602 drives the gate valve to flip, thereby ensuring the polishing quality of the irregular gate valve through the sandblasting process. The automatic oscillating support mechanism 5 improves the polishing efficiency.

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.
