[0002] The pneumatic valve controller adopts advanced technology and has precise control functions. It can accurately adjust the opening and closing actions of pneumatic valves and meet the needs of different application scenarios by adjusting the air source pressure. In addition, the controller also has the advantages of high reliability, simple operation and convenient maintenance. It can respond to instructions quickly and work stably and reliably, bringing convenience and benefits to industrial production.

[0003] The installation of a pneumatic valve controller usually includes the following steps: First, determine the installation location, ensure that it is easy to operate and maintain, and consider the convenience of connection with pipelines and valves.

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] Reference Figure 1 and Figure 2 The utility model provides an embodiment: a pneumatic valve controller that is easy to install, including a valve body 1, a controller body 8 is fixedly connected to the bottom of the valve body 1, connecting rods 2 are fixedly connected to both sides of the outer wall of the controller body 8, a fixed block 3 is fixedly connected to one side of the connecting rod 2, a worm 11 is rotatably connected inside the fixed block 3, a handle 5 is fixedly connected to one end of the worm 11, a rotating shaft 12 is rotatably connected to both sides of the fixed block 3, a worm wheel 13 is fixedly connected to the center of the outer wall of the rotating shaft 12, and a clamping claw 4 is fixedly connected to the outer wall of the rotating shaft 12;

[0033] Specifically, when the controller is fixed, the connecting rod 2 can be used to extend the fixing block 3 to the bottom of the pipe, and then the handle 5 can be used to drive the worm 11 to rotate. Then, the rotation of the worm 11 can drive the worm wheels 13 on both sides, and make the rotating shaft 12 at the center of the worm wheel 13 rotate. When the rotating shaft 12 rotates, it can drive the clamp 4 to rotate, and then the clamp 4 clamps the pipe. In this way, the controller can be hung at the bottom of the pipe through the clamp 4.

[0034] Reference Figure 1 and Figure 3 The outer wall of the controller body 8 is provided with a connection assembly, which includes a connection terminal 6 and a threaded column 7. The connection terminal 6 is fixedly connected to one side of the inside of the controller body 8, and one side of the threaded column 7 is fixedly connected to one side of the outer wall of the controller body 8;

[0035] Specifically, a connection terminal 6 is provided on the controller body 8, and a circuit can be connected through the connection terminal 6 to control the power of the controller. At the same time, a threaded column 7 is provided on the outside of the connection terminal 6, and the threaded column 7 can be used to quickly fix the connection line.

[0036] Reference Figure 3 and Figure 4 , both sides of the outer wall of the valve body 1 are threadedly connected with a rotary handle 10, both sides of the outer wall of the valve body 1 are provided with a ring array of fixing clips 9, one side of the fixing clip 9 is rotatably connected with a transmission rod 18, one side of the inner side of the rotary handle 10 is provided with a slide groove 19, one side of the transmission rod 18 is rotatably connected with a driving block 17, one side of the outer wall of the driving block 17 is fixedly connected with a slider 20, the outer wall of the slider 20 is slidably connected to the inside of the slide groove 19, both sides of the outer wall of the valve body 1 are fixedly connected with a limiting column 14, a limiting groove 21 is provided inside the fixing clip 9, the outer wall of the limiting column 14 is slidably connected to the inside of the limiting groove 21, both sides of the inner side of the valve body 1 are provided with a sealing groove 15, and both sides of the inner side of the valve body 1 are provided with a sealing ring 16;

[0037] Specifically, when the controller is connected to the pipeline, the handle 10 can be rotated, and the block 17 can be driven by the connection between the slider 20 and the slide groove 19. Due to the action of the slider 20, it can adapt to the rotation of the handle 10 while pulling the handle 10 inward, thereby driving the driving block 17 to move. Then, the driving block 17 will pull the fixing clamp 9 through the transmission rod 18. Since the fixing clamp 9 is restricted by the limit column 14 and the limit groove 21 on its movement trajectory, the fixing clamp 9 will clamp inward during the movement, thereby firmly fixing the pipeline. At the same time, the sealing ring 16 will be stuck in the inside of the sealing groove 15, and the sealing groove 15 is set on the connection port, so that the sealing of the connection can be further enhanced.

[0038] Working principle: When the controller is fixed, the fixing block 3 can be extended to the bottom of the pipeline by the connecting rod 2, and then the worm 11 can be driven to rotate by the handle 5. The rotation of the worm 11 can drive the worm wheels 13 on both sides, and the rotating shaft 12 in the center of the worm wheel 13 rotates accordingly. When the rotating shaft 12 rotates, the clamping jaw 4 can be driven to rotate, so that the clamping jaw 4 clamps the pipeline, and the controller can be hoisted at the bottom of the pipeline by the clamping jaw 4. When the controller is connected to the pipeline, the handle 10 can be rotated, and the driving block 17 can be connected to the slide groove 19 through the slider 20. The slider 20 can adapt to the rotation of the handle 10 and pull the handle 10, thereby driving the driving block 17 to move, and then the driving block 17 pulls the fixing clamp 9 through the transmission rod 18. Since the fixing clamp 9 is limited in its movement trajectory by the limiting column 14 and the limiting groove 21, the fixing clamp 9 will clamp inward during the movement, thereby fixing the pipeline, and at the same time, the sealing ring 16 will be stuck in the sealing groove 15. The sealing groove 15 is set at the connection port, thereby increasing the sealing of its connection.

[0039] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
