In addition, the forms of the various structures recorded in the following embodiments are merely illustrative. The portable valve control device involved in the present invention is not limited to the various structures recorded in the following embodiments. All other implementations obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the present invention.

[0020] The utility model provides a portable valve control device, such as Figure 1 As shown, it includes a casing 1, which is arranged on a pipeline 2. Various electronic devices in the device are installed in the inner cavity through the casing 1, so that the overall volume of the device is reduced and it is more convenient to carry. A display screen 3 and a control button 4 are fixedly installed on the top of the casing 1. The operation process of the device is displayed on the display screen 3, and the device is controlled by the control button 4. A controller 5 is fixedly installed on the rear end of the casing 1. The device as a whole is controlled by the controller 5, and there is no need to manually adjust the valve. Two connecting frames 6 are fixedly connected to the bottom of the casing 1 at equal distances, and two fastening bolts 7 are connected to the top of the connecting frame 6 at equal distances. A control component 8 is arranged in the inner cavity of the casing 1. Two fixing rings 9 are fixedly connected to the outer surface of the pipeline 2 at equal distances. A support frame 10 is fixedly connected to the top of the fixing ring 9. The stability of the installation of the support frame 10 is ensured by the fixing ring 9. Fixing holes 11 are opened at both ends of the support frame 10. The support frame 10 is fixed on the fixing ring 9 through the fixing holes 11. A control valve 12 is fixedly installed in the middle of the pipeline 2. A hand wheel 13 is rotatably connected to the top of the control valve 12. The control valve 12 is adjusted by rotating the hand wheel 13.

[0021] Furthermore, the position of the connecting frame 6 corresponds to the position of the supporting frame 10. The connecting frame 6 is located at the top of the supporting frame 10, and the connecting frame 6 is supported by the supporting frame 10. Through holes are opened at equal distances on the top of the supporting frame 10. The bottom end of the fastening bolt 7 passes through the bottom end of the connecting frame 6 and is connected to the inner cavity of the through hole at the top of the supporting frame 10. After the supporting frame 10 is fixed on the surface of the pipeline 2, the connecting frame 6 is fixedly installed on the top of the supporting frame 10 by fastening the bolt 7 to complete the installation of the device.

[0022] Further, such as Figure 2 As shown, the control component 8 includes a motor 81, and the output end of the motor 81 is fixedly connected to a rotating shaft 82, and the rotating shaft 82 is rotated by the motor 81. The bottom end of the rotating shaft 82 is fixedly connected to a mounting block 83, and the mounting block 83 is driven to rotate by the rotating shaft 82. A plurality of limit rods 84 are fixedly connected to the bottom end of the mounting block 83 at equal distances, and the limit rods 84 are moved by the rotation of the mounting block 83.

[0023] Further, such as Figure 3 and Figure 4As shown, the motor 81 is fixedly installed in the inner cavity of the casing 1, and the mounting block 83 is rotatably connected to the bottom end of the casing 1, and the casing 1 plays a protective role on the motor 81. The position of the limit rod 84 corresponds to the position of the handwheel 13, and the limit rod 84 runs through the inner cavity of the handwheel 13. When the valve needs to be adjusted, the control valve 12 is rotated by turning the handwheel 13 to adjust the valve. When the connecting frame 6 and the supporting frame 10 are installed, the limit rod 84 is stuck in the cross bar position inside the handwheel 13, and the handwheel 13 is driven to rotate by the rotation of the limit rod 84. The motor 81 replaces manual rotation of the handwheel 13. When rust or jamming occurs at the rotation position of the handwheel 13, the motor 81 replaces manual rotation, which is more convenient and quick to use.

[0024] The working principle of the utility model is as follows: first, the support frame 10 is installed on the outer surface of the pipe 2 through the fixing ring 9, and the support frame 10 is fixed through the fixing hole 11. After the fixing is completed, the device as a whole is fixed to the top of the support frame 10 through the connecting frame 6, and the bottom end of the fastening bolt 7 passes through the bottom end of the connecting frame 6 and is connected to the inner cavity of the through hole at the top of the support frame 10 to complete the installation of the device. After the device is installed, the limit rod 84 will be stuck at the crossbar position inside the handwheel 13. When in use, the device is controlled by the controller 5, the display screen 3 displays the operation process and data of the device, and the device is controlled by the control button 4. When in use, the motor 81 is started, and the motor 81 makes The rotating shaft 82 rotates, and the rotating shaft 82 drives the mounting block 83 to rotate. Since the pipeline 2 and the valve are in an unused state most of the time, the handwheel 13 controlling the valve 12 may be rusted or stuck at the rotation position after a long time, and it is difficult for the staff to rotate it manually, which affects the adjustment of the valve control. When the mounting block 83 rotates, it drives the limit rod 84 to move, and the rotation of the limit rod 84 drives the handwheel 13 to rotate. The motor 81 replaces manual rotation of the handwheel 13, which is more convenient and quick to use. At the same time, the casing 1 installs various electronic equipment in the device in the inner cavity, which reduces the overall size of the device and is more convenient to carry.
