[0011] A method for using a processing tool for a valve seal for a nuclear power plant comprises the following steps:

[0012] S1: When the device starts working, the operator first pours the raw materials of the non-metallic seal into the connecting tube, starts the first motor through an external power supply, the first motor drives the first transmission rod to rotate, the first transmission rod drives the fixed block to rotate, the first transmission rod drives the limit L-shaped rod and the stirring plate to rotate, the stirring plate stirs and mixes the raw materials of the non-metallic seal, and when the stirring and mixing is completed, the discharge valve at the discharge pipe is opened, the stirred material will enter the storage frame through the discharge pipe, the storage frame is taken out, and the material is subsequently processed to make a non-metallic seal;

[0013] S2: When the first motor is stirring and mixing the raw materials of the non-metallic seal, the metal seal to be polished is placed on the top of the support plate through an external device, and the threaded cylinder is located on the top. The operator moves the pressing plate downward, and the pressing plate drives the elastic rod to move, and the elastic rod drives the adjacent fan-shaped blocks to move. The round tube supports the fan-shaped blocks. When the position of the fan-shaped blocks is close to one side of the metal seal to be polished, the operator takes out the cross rod, and the cross rod drives the limiting threaded rod to move, and rotates the limiting threaded rod to pass through the pressing plate and enter the hole on the top of the cross plate, thereby limiting the pressing plate. After that, the polishing paper is surrounded into a circle and sleeved on the surface of the four fan-shaped blocks. The joints of the polishing paper are bonded by glue, and the elastic frame is squeezed. The elastic frame drives the elastic box to be squeezed, and the glue inside the elastic box flows into the telescopic tube through the fixed tube, and then flows from the telescopic tube into the nozzle, and is attached to one side of the polishing paper through the nozzle;

[0014] S3: After step S2, the operator pulls the elastic cloth, and the elastic cloth is limited by the limiting plate. In the process of gradually closing, the elastic cloth will drive the four fixed columns to gradually move closer to the center of the support plate, and the fixed column drives the vertical rod to move, and the vertical rod drives the spring to stretch, and the vertical rod drives the fixed plate and the threaded barrel to move, and the threaded barrel drives the connecting threaded rod and the rotating disk to move, so that the surface of the threaded barrel gradually fits the surface of the metal seal. If the height of the metal seal is high, the operator adjusts the rotating disk, and the rotating disk drives the connecting threaded rod to rotate inside the threaded barrel, thereby expanding the limiting range of the metal seal. During grinding, the second motor is started by an external power supply, and the second motor drives the second transmission rod to rotate, and the second transmission rod drives the cross plate to rotate, and the cross plate drives the elastic frame and the elastic box to rotate. The cross plate drives the elastic rod and the fan-shaped block to rotate through the round tube, and the grinding paper on the surface of the four fan-shaped blocks will grind one side of the metal seal;

[0015] S4: When a separate metal seal blank needs to be processed, the support plate and related components need to be removed from the surface of the connecting tube. The operator moves the support plate upward through external equipment. The support plate drives the ring upward through the connected L-shaped rod to remove the ring from the surface of the connecting tube. The universal wheel drives the support plate to move. Then the operator turns the bolt to remove the bolt from the bottom of the support plate and the fixed plate, so as to facilitate the disassembly of the first motor. After that, the operator swings the L-shaped plate and the elastic plate outward to rotate the support plate. The fixed column originally located at the bottom will rotate to the top. After the rotation of the support plate is completed, one side of the L-shaped plate is placed under the support plate again, and the support column and the chassis are taken out. The support column is rotated to the inside of the threaded tube through the external thread to support the support plate. Then the load-bearing plate and the insertion rod are taken out, and the insertion rod is inserted into the hole on one side of the adjacent fixed column. The load-bearing plate forms a new platform, and the metal blank is placed on the top of the load-bearing plate, which is convenient for processing and cutting the metal blank to make a metal seal.

[0016] S5: When the material of the non-metallic seal is made into a non-metallic seal, the operator repeats the steps of S2 and S3 to grind the surface of the non-metallic seal.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] The present invention realizes that the device can process metal seals and non-metal seals through the mutual cooperation between the first motor, the connecting tube, the discharge pipe, the stirring plate and other structures. The raw materials of the non-metal seals, such as rubber, filler, vulcanizer, etc., are poured into the connecting tube, and the first motor drives the stirring plate to rotate. The stirring plate stirs and mixes the raw materials of the non-metal seals. The discharge valve at the discharge pipe is opened, and the mixed material will flow out. The material is subsequently processed and formed. For the processing of the metal seal embryo, the support plate is rotated, the first motor is removed, and the load-bearing plate is taken out and placed on one side of the fixed column, and the metal embryo is placed on one side of the load-bearing plate, and the metal embryo is cut. When it is necessary to polish the surface of the metal seal and the non-metal seal, the support plate is turned over again, and the seal is placed on one side of the support plate. The fan-shaped block and the threaded tube are moved respectively to limit the seal, and the seal is polished by the polishing paper wrapped around the surface of the four fan-shaped blocks.

[0043] A method for using a processing tool for a valve seal for a nuclear power plant comprises the following steps:

[0044] S1: When the device starts working, the operator first pours the raw materials of the non-metallic seal into the connecting tube 2, and starts the first motor 10 through an external power supply. The first motor 10 drives the first transmission rod 11 to rotate, and the first transmission rod 11 drives the fixed block 45 to rotate. The first transmission rod 11 drives the limiting L-shaped rod 15 and the stirring plate 16 to rotate, and the stirring plate 16 stirs and mixes the raw materials of the non-metallic seal. When the stirring and mixing is completed, the discharge valve 42 at the discharge pipe 13 is opened, and the stirred material will enter the storage frame 8 through the discharge pipe 13, and the storage frame 8 will be taken out, and the material will be subsequently processed to make a non-metallic seal;

[0045] S2: When the first motor 10 is stirring and mixing the raw materials of the non-metallic seal, the metal seal to be polished is placed on the top of the support plate 1 through an external device, and the threaded tube 18 is located on the top. The operator moves the pressing plate 48 downward, and the pressing plate 48 drives the elastic rod 33 to move, and the elastic rod 33 drives the adjacent sector block 27 to move. The round tube 30 supports the sector block 27. When the sector block 27 is close to one side of the metal seal to be polished, the operator takes out the cross rod 46, and the cross rod 46 drives the limiting threaded rod 47 to move. The limit threaded rod 47 is rotated to penetrate the pressing plate 48 and enter the hole at the top of the cross plate 28, thereby limiting the pressing plate 48. Then, the grinding paper is formed into a circle and sleeved on the surface of the four sector blocks 27. The connection of the grinding paper is bonded by glue, and the elastic frame 29 is squeezed. The elastic frame 29 drives the elastic box 34 to be squeezed. The glue inside the elastic box 34 flows into the telescopic tube 36 through the fixed tube 35, and then flows from the telescopic tube 36 to the nozzle 37, and is attached to one side of the grinding paper through the nozzle 37.

[0046] S3: After step S2, the operator pulls the elastic cloth 25, and the elastic cloth 25 is limited by the limiting plate 26. In the process of gradually closing, the elastic cloth 25 will drive the four fixed columns 24 to gradually move closer to the center of the support plate 1, and the fixed column 24 drives the vertical rod 23 to move, and the vertical rod 23 drives the spring 22 to stretch, and the vertical rod 23 drives the fixed plate 21 and the threaded cylinder 18 to move, and the threaded cylinder 18 drives the connecting threaded rod 20 and the rotating disk 19 to move, so that the surface of the threaded cylinder 18 gradually fits the surface of the metal seal. If the height of the metal seal is high When the operator adjusts the rotating disk 19, the rotating disk 19 drives the connecting threaded rod 20 to rotate inside the threaded barrel 18, thereby expanding the limiting range of the metal seal. When grinding, the second motor 31 is started by an external power supply, the second motor 31 drives the second transmission rod 32 to rotate, the second transmission rod 32 drives the cross plate 28 to rotate, the cross plate 28 drives the elastic frame 29 and the elastic box 34 to rotate, the cross plate 28 drives the elastic rod 33 and the fan-shaped block 27 to rotate through the round tube 30, and the grinding paper on the surface of the four fan-shaped blocks 27 will grind one side of the metal seal;

[0047] S4: When a separate metal seal blank needs to be processed, the support plate 1 together with related components must be removed from the surface of the connecting tube 2. The operator moves the support plate 1 upward through an external device. The support plate 1 drives the ring 6 to move upward through the connected L-shaped rod 5, and the ring 6 is removed from the surface of the connecting tube 2. The universal wheel 9 drives the support plate 1 to move. Then the operator turns the bolt 44 and removes the bolt 44 from the bottom of the support plate 1 and the fixing plate 14, so as to facilitate the disassembly of the first motor 10. Then the operator swings the L-shaped plate 3 and the elastic plate 4 outward to the support plate 1. After rotating 180 degrees, the fixed column 24 originally located at the bottom will rotate to the top. After the support plate 1 is rotated, one side of the L-shaped plate 3 is placed under the support plate 1 again, and the support column 39 and the bottom plate 40 are taken out. The support column 39 is rotated into the threaded tube 49 through the external thread to support the support plate 1. Then, the load-bearing plate 38 and the insertion rod 41 are taken out, and the insertion rod 41 is inserted into the hole on one side of the adjacent fixed column 24. The load-bearing plate 38 forms a new platform, and the metal blank is placed on the top of the load-bearing plate 38, which is convenient for processing and cutting the metal blank to make a metal seal.

[0048] S5: When the material of the non-metallic seal is made into a non-metallic seal, the operator repeats the steps of S2 and S3 to grind the surface of the non-metallic seal.

[0049] Working principle: When the device starts working, the operator first pours the raw materials of the non-metallic seal into the connecting tube 2, and starts the first motor 10 through an external power supply. The first motor 10 drives the first transmission rod 11 to rotate, and the first transmission rod 11 drives the fixed block 45 to rotate. The first transmission rod 11 drives the limiting L-shaped rod 15 and the stirring plate 16 to rotate, and the stirring plate 16 stirs and mixes the raw materials of the non-metallic seal.
