[0002] A valve cover is a valve part equipped with a valve stem seal, used to connect or support an actuator. The valve cover and the valve body can be an integral part or separated. In a gate valve, the valve cover mainly functions to compress the packing. Currently, the shapes of valve bodies vary, resulting in different shapes of valve covers, and processing tooling is required during processing.

[0003] For example, Chinese Patent Publication No. CN221211262U discloses a valve cover processing tooling, including a base, a support member, a telescopic rod, a shock-absorbing spring, and a tray.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] Please refer to Figures 1-5 , the present invention provides a technical solution for a new valve cover processing tooling: including a fixed seat 1 and a valve cover 2. A through-type annular opening 3 is provided at the center position of the outer top of the fixed seat 1. A rotating seat 4 is rotatably connected to the inner side wall of the annular opening 3 and inside the fixed seat 1. The valve cover 2 is placed at the center position of the outer top of the rotating seat 4. Through-type chutes 5 arranged at equal intervals in a ring shape are provided on the outer top of the rotating seat 4. Four groups of chutes 5 are internally slidably connected with arc-shaped clamping blocks 6 for limiting and abutting the four sides of the outside of the valve cover 2. And a downward pressing assembly for pressing the valve cover 2 is provided on the outer top of the arc-shaped clamping blocks 6. The downward pressing assembly includes an annular support plate 13 fixedly installed on the outer tops of the four groups of arc-shaped clamping blocks 6. A top plate 14 is fixedly installed on the outer tops of the four support plates. A pressing block 15 is provided below the top plate 14 and on the outer side walls corresponding to the support plates. Rotating sleeves 16 are fixedly installed on the outer tops of the four groups of pressing blocks 15. A second threaded rod 17 is rotatably connected to the outer top of the top plate 14. One end of the second threaded rod 17 penetrates through the top plate 14 and extends below the top plate 14, and is rotatably connected to the inside of the rotating sleeve 16. Vertical straight slots 18 are provided on the outer side walls of the four support plates. A T-shaped block 19 is provided on the outer side wall of the support plate. And one end of the T-shaped block 19 is fixedly connected to the outer side wall of the arc-shaped clamping block 6. At the same time, the T-shaped block 19 is slidably connected to the inside of the straight slot 18. When pressing down, first place the valve cover 2 at the middle position of the outer top of the rotating seat 4. Then, turn the second threaded rod 17 to rotate it inside the rotating sleeve 16, and thereby drive the pressing block 15 and the T-shaped block 19 to move downward along the straight slot 18, so that the pressing block 15 presses the edge of the valve cover 2 to improve the limiting and fixing effect on the valve cover 2.

[0025] On the inner bottom surface of the rotating seat 4, there is also a fixing component that drives the arc-shaped clamping block 6 to move relatively to limit valve covers 2 of different sizes and shapes. The fixing component includes a first threaded rod 7 rotatably connected to the inner top surface of the rotating seat 4. The end of the first threaded rod 7 is fixedly connected to the output end of a driving motor 8 fixedly installed at the center position of the inner bottom surface of the rotating seat 4. A sleeve 9 is threadedly sleeved on the outer peripheral surface of the first threaded rod 7. And first ear plates 10 are fixedly arranged at equal intervals on the outer peripheral side wall of the sleeve 9. Second ear plates 11 are fixedly installed on the outer bottoms of the four arc-shaped clamping blocks 6. And a connecting plate 12 is rotatably connected inside the four second ear plates 11. One ends of the four connecting plates 12 away from the second ear plates 11 are rotatably connected inside the first ear plates 10. When performing limit fixation, start the driving motor 8 to drive the sleeve 9 on the first threaded rod 7 to move up and down, so that the connecting plate 12 on the first ear plate 10 drives the second ear plate 11 to move relatively, and then the second ear plate 11 drives the four arc-shaped clamping blocks 6 to approach or move away from each other along the inner side of the sliding groove 5, so that the arc-shaped clamping blocks 6 are in close contact with the outer peripheral side wall of the valve cover 2, firmly fixing the valve cover 2 on the rotating seat 4, thus facilitating the clamping and limiting of valve covers 2 of different sizes and shapes and being beneficial to improving the applicability.

[0026] On the inner bottom surface of the fixed seat 1, there is a driving component for driving the rotating seat 4 to rotate. The driving component includes a connecting rod 20 rotatably connected to the center position of the outer bottom of the rotating seat 4. The end of the connecting rod 20 is rotatably connected to the inner bottom surface of the fixed seat 1. And a worm gear 21 is fixedly installed on the outer peripheral surface of the connecting rod 20. A worm 22 is rotatably connected between the two inner side walls of the fixed seat 1. The worm gear 21 and the worm 22 are meshed. One end of the worm 22 penetrates through the fixed seat 1 and extends to the outer side wall of the fixed seat 1. And a knob 23 is also fixedly installed on the outer peripheral surface of the worm 22. When performing angle rotation, by turning the knob 23 to drive the worm 22 to rotate, the worm gear 21 is driven to drive the connecting rod 20 to rotate, and then the connecting rod 20 drives the rotating seat 4 to rotate along the annular opening 3, and then the valve cover 2 rotates to change the position of the valve cover 2, so as to better process the valve cover 2, having good use flexibility.

[0027] The working principle of the present utility model is as follows: When in use, first place the valve cover 2 to be processed on the rotating seat 4, and then start the driving motor 8 to drive the sleeve 9 on the first threaded rod 7 to move up and down, so that the connecting plate 12 on the first ear plate 10 drives the second ear plate 11 to move relatively, and then the second ear plate 11 drives the four arc-shaped clamping blocks 6 to approach or move away from each other along the inner side of the sliding groove 5, so that the arc-shaped clamping blocks 6 are in close contact with the outer peripheral side wall of the valve cover 2, firmly fixing the valve cover 2 on the rotating seat 4.

[0028] Meanwhile, turn the second threaded rod 17 to make it rotate inside the rotating sleeve 16, and thereby drive the pressing block 15 and the T-shaped block 19 to move downward along the straight groove 18, so that the pressing block 15 presses the edge of the valve cover 2 to improve the limiting and fixing effect on the valve cover 2.

[0029] At the same time, turn the knob 23 to drive the worm 22 to rotate, so as to drive the worm wheel 21 to drive the connecting rod 20 to rotate. Furthermore, let the connecting rod 20 drive the rotating seat 4 to rotate along the annular opening 3, and then make the valve cover 2 rotate to change the position of the valve cover 2, so as to machine other positions of the valve cover 2. The operation is simple and convenient to use.

[0030] After the machining is completed, the valve cover 2 can be taken out by operating in the reverse direction.

[0031] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model. The structures, devices and operation methods not specifically described and explained in the present utility model, unless otherwise specified and limited, are implemented according to the conventional means in the art.
