[0002] The opening and closing member of a ball valve is a sphere with a circular through-hole. The sphere is driven by a valve stem and rotates around the axis of the ball valve. During the opening and closing process, the sphere rotates around its central axis. When the sphere rotates to a specific position, the hole passage on it will align or stagger with the passage of the valve body, thereby realizing the on-off of the fluid. Due to its excellent performance characteristics, the ball valve is widely used in many fields such as petroleum refining, natural gas transportation, chemical industry, electric power industry, pharmaceutical and life sciences, water treatment and water supply, HVAC systems, construction industry, and food and beverage processing.

[0004] During the use of existing ball valves, since some ball valves need to be used in a high-temperature environment, and the high-temperature environment is most likely to cause damage or slight deformation of the parts themselves. Therefore, it is necessary to solve how to avoid high-temperature resistance during the use of ball valves.

A second rotating cylinder 206 is rotatably connected above the cross mount 101, and the second rotating cylinder 206 is sleeved with the first rotating cylinder 203.

[0027] The electric push rod 205 can drive the lifting platform 201 to move up and down, so that the first rotating cylinder 203 slides along the upper part of the second rotating cylinder 206.

[0028] Further, in the above structure, limiting grooves one 207 are symmetrically formed on the inner wall of the second rotating cylinder 206.

A first spring 210 is attached between the first pushing cylinder 208 and the second rotating cylinder 206.

[0029] Through the cooperation of the limiting blocks one 209 and the limiting grooves one 207, the first pushing cylinder 208 can slide within the second rotating cylinder 206, and the first spring 210 can keep the position of the first pushing cylinder 208 within the second rotating cylinder 206. When the first rotating cylinder 203 is pressed down, the first spring 210 can be compressed, thereby generating a large frictional force to drive the second rotating cylinder 206 to rotate by the motor 202.

[0030] Further, in the above structure, the transmission assembly 003 further includes bevel gears 302. The bevel gears 302 are rotatably connected above the cross-shaped fixing frame 101.

[0034] Further, in the above structure, the driving assembly 004 further includes a docking shaft 409. The docking shaft 409 is rotatably connected within the cross-shaped fixing frame 101. The lower part of the docking shaft 409 is fixedly connected to the connecting plate 401, and the upper part of the docking shaft 409 is axially connected to the second rotating cylinder 206.

[0035] Through the connection between the docking shaft 409 and the second rotating cylinder 206, the docking shaft 409 can drive the connecting plate 401 to rotate.

[0036] Furthermore, in the above structure, an internally threaded cylinder 407 is threadedly sleeved on the threaded rod 404. Guide blocks 408 are symmetrically installed on the outer side of the internally threaded cylinder 407. Guide grooves 406 are symmetrically formed on the inner wall of the through hole 405, and the guide grooves 406 are slidably connected to the corresponding guide blocks 408.

[0037] By rotating the threaded rod 404, the internally threaded cylinder 407 moves downward, and the cooperation between the guide blocks 408 and the guide grooves 406 enables the internally threaded cylinder 407 to move more smoothly.

[0038] Furthermore, in the above structure, the grasping assembly 005 further includes a connecting shaft 504. The connecting shafts 504 are symmetrically installed and connected below the internally threaded cylinder 407. A rotating seat 506 is rotatably connected below the two groups of connecting shafts 504. Limit sliding rails 505 are installed inside the two groups of grasping plates 503, and the limit sliding rails 505 are slidably connected to the corresponding rotating seats 506.

[0039] By the movement of the internally threaded cylinder 407, the connecting shaft 504 can drive the rotating seat 506 to slide in the limit sliding rail 505, so that the grasping plates 503 can perform the closing and opening actions to grasp the valve core.

[0040] A processing and production process for a high-temperature resistant ball valve includes a high-temperature resistant ball valve processing device as above, and the processing steps are as follows: S1: By placing the processed valve core above the placing seat 104, at this time, the lifting platform 201 moves downward, so that the motor 202 drives the connecting plate 401 to rotate, so that the grasping plates 503 move above the valve core. At this time, the lifting platform 201 moves upward, so that the motor 202 drives the bidirectional bevel gear shaft 301 to rotate; S2: Through the transmission of power, the power of the bidirectional bevel gear shaft 301 drives the threaded rod 404 to rotate, so that the internally threaded cylinder 407 moves downward, and the grasping plates 503 open to pick up the valve core; S3: As the connecting plate 401 rotates, the valve core enters the heating furnace 102 for heating, and then enters the cooling barrel 103 for cooling, thereby completing the quenching of the valve core, thereby improving the high-temperature resistance of the valve core. And through the grasping of the two groups of grasping plates 503, the continuous progress of the quenching work can be ensured.

[0041] As Figures 1-9As shown in the figure, by placing the valve core to be processed above the placing seat one 104, at this time, the electric push rod 205 drives the lifting table 201 to move downward, so that the first rotating cylinder 203 presses the first pushing cylinder 208 downward. At this time, the motor 202 is started, and the motor 202 can transmit the power to the second rotating cylinder 206 through the first rotating cylinder 203, thereby driving the connecting plate 401 below the docking shaft 409 to rotate, so that the grasping plate 503 moves above the placing seat one 104. At the same time, the upper connecting seat 403 can cooperate with the new second pushing cylinder 305 after the connecting plate 401 rotates, and the electric push rod 205 drives the lifting table 201 to move upward, so that the bevel gear ring 204 meshes with the double bevel gear shaft 301.

[0042] Thus, the motor 202 transmits the power to the double bevel gear shaft 301 and transmits the power to the rotating shaft 303 through the bevel gear 302, so that the second pushing cylinder 305 drives the threaded rod 404 to rotate, so that the internal thread cylinder 407 moves downward, and drives the second limiting cylinder 502 to slide along the first limiting cylinder 501. When the second limiting cylinder 502 slides in place, at this time, the connecting shaft 504 drives the rotating seat 506 to slide along the limiting slide rail 505, so that the grasping plate 503 opens and completes the grasping of the valve core with the subsequent reset.

[0043] And through the rotation of the connecting plate 401, the valve core is moved above the heating furnace 102, heated and then placed into the cooling barrel 103 by the same method. And during the process of placing it into the cooling barrel 103, another set of grasping plates 503 completes the grasping of the new valve core, so that one set can be in the heating process while the other set is in the cooling process. When the processing is completed, the valve core can be placed on the placing seat two 105 and wait for the finished product to be collected.

[0044] In this way, the quenching work of the valve core can be automatically completed, which improves the heat resistance of the valve core. At the same time, it can also improve the quenching processing efficiency of the valve core, reduce the working intensity of the operators, and also reduce the manufacturing cost and manufacturing difficulty of the device.

[0045] Only some exemplary embodiments of the present invention are described by way of illustration above. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present invention, the described embodiments can be modified in various different ways. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the protection scope of the claims of the present invention.
