Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of safety valve adjustment tools, specifically relating to an electric safety valve adjustment device. Background Technology
[0002] As a crucial safety protection device in industrial pressure systems, the accuracy of a safety valve's opening and closing pressure directly impacts equipment operational safety and system stability. During the calibration and maintenance of safety valves, the rotational precision and operational efficiency of the adjusting nut play a decisive role in setting pressure parameters. Traditional adjustment methods often rely on manual operation using wrenches, resulting in high labor intensity and low adjustment efficiency.
[0003] In recent years, with the development of automation technology, some electric torque tools have begun to be used in the field of valve adjustment. However, existing electric tools are limited by the fixed-size sleeve structure, making it difficult to match the hexagonal adjusting nuts of different models of safety valves, resulting in poor compatibility.

[0021] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.
[0022] like Figures 1-4As shown, an adjustment device for an electric safety valve includes a main ring body 1, an inner ring body 2 rotatably connected inside the main ring body 1, and multiple clamping plates 3 installed inside the inner ring body 2 via multiple telescopic arms. The multiple clamping plates 3 are arranged in a ring array inside the inner ring body 2. At this time, by adjusting the distance between the clamping plates 3 and the center of the inner ring body 2 through the telescopic arms, hexagonal nuts of different sizes can be adapted to fit the adjustment nuts of different models of safety valves.
[0023] like Figures 1-2 As shown, the telescopic arm includes a threaded sleeve 6 rotatably connected to the inner ring body 2. The threaded sleeve 6 has a threaded rod 5 connected to its internal thread. One end of the threaded rod 5 is fixedly connected to the clamping plate 3. At this time, by rotating the threaded sleeve 6, the threaded rod 5 can be moved to extend and retract, thereby adjusting the position of the clamping plate 3. After adjustment, it has good self-locking stability.
[0024] The clamping plate 3 is also fixedly connected to a slide rod 4 that is slidably connected to the inner ring body 2. The slide rod 4 can reduce the rotation of the clamping plate 3 and improve the stability of the clamping plate 3.
[0025] like Figures 1-2 As shown, bevel gears 7 are rotatably connected to the outer sides of multiple threaded sleeves 6, and bevel gear rings 8 are rotatably connected to the outer sides of the inner ring body 2. The bevel gears 7 and bevel gear rings 8 are meshed together. At this time, kinetic energy can be synchronously input into the threaded sleeves 6 by rotating the bevel gear rings 8, which synchronously drives the six clamping plates 3 to move.
[0026] The outer sides of the inner ring 2 and the bevel gear ring 8 can be fixedly connected with ring handles 9. By rotating the two ring handles 9 in opposite directions, the user can easily turn the bevel gear ring 8 by hand.
[0027] like Figures 1-2 In order to electrically drive the adjusting nut to rotate, this technical solution has a drive motor 10 fixedly connected to the main ring 1 and driven by the main ring 1. The drive motor 10 can be started by an external power supply or a battery installed on the device itself, which can drive the inner ring 2 to rotate.
[0028] Specifically, the output end of the drive motor 10 is fixedly connected to a meshing gear 11, and the outer side of the inner ring body 2 is fixedly connected to a meshing ring 12 that meshes with the meshing gear 11, so that the transmission can be stably completed through meshing.
[0029] like Figure 1 and Figure 3 As shown, a handle is fixedly connected to the outside of the main ring 1. Users can easily hold and position the main ring 1 by holding the handle.
[0030] The handle includes a first handle rod 13 fixedly connected to the outside of the main ring body 1, and a second handle rod 14 movably connected to the outside of the first handle rod 13, so that the second handle rod 14 can be kept parallel to the first handle rod 13 or kept vertical. When the first handle rod 13 and the second handle rod 14 are kept parallel, the user can hold the end of the second handle rod 14 to increase the torque and position the main ring body 1 with less effort. When the second handle rod 14 and the first handle rod 13 are kept perpendicular, the second handle rod 14 can abut against the pipe connected to the safety valve. The pipe can bear the torque transmitted to the second handle rod 14 by the main ring body 1 and the inner ring body 2, so that the second handle rod 14 and the main ring body 1 can be positioned with less effort.
[0031] Specifically, such as Figures 3-4 As shown, a worm gear 19 and two rotating rods 17 are rotatably connected to the outer side of the first handle 13. The two rotating rods 17 are fixedly connected to one end of the second handle 14. One of the rotating rods 17 is fixedly connected to the outer side of a worm wheel 18 that meshes with the worm gear 19. By rotating the worm gear 19, the worm wheel 18 can be driven to rotate, thereby rotating the second handle 14 to freely adjust the angle of the second handle 14.
[0032] A sliding ring 15 is slidably connected to the outside of the first handle 13. The rotating rod 17 and the worm gear 19 are both rotatably connected to the sliding ring 15. The rotating rod 17 and the worm gear 18 rotate directly to the outside of the first handle 13. When the rotating rod 17 and the worm gear 19 are both rotatably connected to the sliding ring 15, the position of the second handle 14 can be adjusted by moving the sliding ring 15. A locking screw 16 is threaded onto the sliding ring 15. When the locking screw 16 abuts against the first handle 13, the position of the sliding ring 15 can be locked.
[0033] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
