[0028] Embodiment:

[0029] Please refer to Figures 1-5The utility model provides an easy maintenance city heating regulating valve, including valve body 1 and fixed rod 14, the inside sliding joint of fixed rod 14 has sliding rod 17, and the middle part of one side of sliding rod 17 is fixedly connected with no.

[0030] Please refer to Figures 1-5 The outer wall of fixed rod 14 is provided with screw thread line 15, and screw block 21 is screw-connected outside screw thread line 15, in the scheme, the connection between screw block 21 and screw thread line 15 makes screw block 21 rotatable outside fixed rod 14.

[0031] Please refer to Figures 1-5 One end of fixed rod 14 is fixedly connected with leverage block 22, and leverage block 22 is arc-shaped, in the scheme, the staff can hold leverage block 22 to rotate screw block 21, thereby avoiding the rotation of fixed rod 14 due to excessive friction between screw block 21 and fixed rod 14.

[0032] Please refer to Figures 1-5 The outer wall of fixed rod 14 is provided with screw thread line 15, and screw block 21 is screw-connected outside screw thread line 15, in the scheme, the connection between screw block 21 and screw thread line 15 makes screw block 21 rotatable outside fixed rod 14.

[0033] Please refer to Figures 1-5The length of the support rod 19 is the same as the length of the movable slot 16, and in this scheme, the support rod 19 can be completely accommodated in the inside of the movable slot 16 because the length of the support rod 19 is the same as the length of the movable slot 16.

[0034] Please refer to Figures 1-5 The valve body 1 is rotationally connected with a valve core 11, and the valve body 1 is fixedly connected with an electric cylinder 12, and the output end of the electric cylinder 12 is rotationally connected with the rotating shaft of the valve core 11, and in this scheme, the electric cylinder 12 provides power for the rotation of the valve core 11.

[0035] Working principle: if the staff needs to disassemble and maintain the connection pipe 13 and the valve body 1, the threaded block 21 can be rotated by a small number of turns, and only when the staff observes that the fixed rod 14 and the valve body 1 and the connection pipe 13 are loose, the sliding rod 17 is pressed along the inside of the fixed rod 14, when the staff presses the sliding rod 17 along the direction of the inside of the fixed rod 14, the end of the sliding rod 17 will extrude the one end of the support rod 19 inside the fixed rod 14, and then the four support rods 19 will rotate towards the inside of the movable slot 16, and in this process, the first spring 18 and the second spring 2 will be elastically deformed and contracted, and as the sliding rod 17 continuously extrudes the support rod 19, when the first spring 18 is shortened to the limit distance, the support rod 19 is completely rotated to the inside of the movable slot 16, and then only the fixed rod 14 is pulled out from the inside of the valve body 1 and the connection pipe 13, and after the fixed rod 14 is completely separated, the connection pipe 13 and the valve body 1 are separated, and in the same way, if the inside maintenance outer wall of the valve body 1 needs to install the valve body 1 and the connection pipe 13, the connection pipe 13 and the valve body 1 are installed, and then the sliding rod 17 is pressed to rotate the support rod 19 to the inside of the movable slot 16, and then the fixed rod 14 is inserted into the corresponding hole of the valve body 1 and the connection pipe 13, and after the support rod 19 passes through the outer wall of the valve body 1, the sliding rod 17 is loosened, at this time, the support rod 19 will reset and expand, and then the threaded block 21 is rotated to fasten the valve body 1 and the connection pipe 13.
