[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Please see Figures 1 to 4 In this embodiment of the present invention, a heating temperature-controlled electric valve control device includes a valve seat 1 connected to a pipeline. A valve plate 2 is rotatably mounted on the inner wall of the valve seat 1. An upwardly extending guide rod 3 is integrally formed on the top of the valve plate 2. The guide rod 3 is rotatably connected to the valve seat 1. A main shaft 4 is rotatably mounted on the outer wall of the guide rod 3. An electric control component is mounted on the outer wall of the main shaft 4. The electric control component is used to control the opening and closing of the valve plate 2 under normal conditions. A manual component extending into the interior of the main shaft 4 is provided at the top of the main shaft 4. The manual component is used to control the opening and closing of the valve plate 2 under abnormal conditions.

[0024] In this embodiment: Under normal conditions, the temperature sensor transmits the temperature data inside the heating pipe to the controller in real time. When the temperature is lower than the preset temperature, the controller controls the electric control component to open the valve plate 2 to a greater angle, allowing more heat-carrying medium to enter the heating pipe. When the temperature inside the heating pipe reaches the preset maximum temperature, the controller controls the electric control component to run in reverse, reducing the opening angle of the valve plate 2 to prevent the temperature from becoming too high.

[0025] In special circumstances (such as when the electric control component is damaged, or when the temperature emitted by the heating pipe is too high or too low), the opening and closing angle of the valve plate 2 can be adjusted by manually adjusting the component.

[0026] Please refer to this carefully. Figure 1 The electric control assembly includes a forward and reverse motor 5, the output end of which is connected to a first worm gear 6, and a first worm wheel 10 that meshes with the first worm gear 6 is interference-fitted to the outer wall of the main shaft 4; the electric control assembly also includes a second worm gear 7 formed to the outer wall of the main shaft 4, and a second worm wheel 8 that meshes with the outer circumference of the second worm gear 7, and the second worm wheel 8 is connected to the rotating part of the photoelectric encoder 9 through a connecting shaft.

[0027] In this embodiment: the temperature sensor converts the temperature signal into an electrical signal and sends it to the controller. The controller controls the forward and reverse motor 5 to rotate according to the electrical signal. The forward and reverse motor 5 drives the first worm gear 6 to rotate. The rotation of the first worm gear 6 drives the first worm wheel 10 to rotate. The first worm wheel 10 can drive the main shaft 4 to rotate. The rotation of the main shaft 4 drives the guide rod 3 to rotate through the part of the manual component located inside the main shaft 4. The guide rod 3 can drive the valve plate 2 to open or close.

[0028] At the same time, the main shaft 4 drives the second worm gear 7 to rotate, the second worm gear 7 drives the second worm wheel 8 to rotate, and the second worm wheel 8 drives the rotating part of the photoelectric encoder 9 to rotate through the connecting shaft. The photoelectric encoder 9 can then transmit the rotation angle of the valve plate 2 to the controller, so that personnel can know the state of the valve plate 2.

[0029] Please refer to this carefully. Figure 2 A first fixing plate 16 is fixedly installed on the outer periphery of the handwheel 11, and a second fixing plate 17 is fixedly installed on the outer periphery of the main shaft 4. The second fixing plate 17 has screw holes inside, and the first fixing plate 16 has a circular groove aligned with the screw holes on its vertical plate.

[0030] In this embodiment: when the electric control component is damaged and the valve plate 2 cannot be adjusted, a tool is used to remove the bolt connected to the screw hole. At this time, the first fixing plate 16 and the second fixing plate 17 are separated, and the handwheel 11 is no longer limited.

[0031] Please refer to this carefully. Figure 3 and Figure 4 The guide rod 3 has a square groove inside and a through hole at the top. The inner cavity of the through hole is connected to the inner cavity of the square groove. A rectangular plate 18 is slidably connected to the inner wall of the square groove. The sliding rod 13 passes through the through hole and is connected to the top of the rectangular plate 18. A spring 19 is connected between the bottom end of the rectangular plate 18 and the bottom end of the inner wall of the square groove.

[0032] In this embodiment: the unlimited handwheel 11 does not have effective small pressure. At this time, the spring 19 resets and pushes the rectangular plate 18 to move upward along the inner wall of the square groove. The rectangular plate 18 synchronously drives the sliding rod 13 to move upward. The upward movement of the sliding rod 13 drives the handwheel 11 to move upward through the fixed rod 12.

[0033] Please refer to this carefully. Figure 3 and Figure 4The manual assembly includes a handwheel 11 rotatably mounted on the top of the main shaft 4. A fixed rod 12 extending downward is fixedly connected to the center of the bottom end of the handwheel 11. A sliding rod 13 that slides vertically and vertically with the guide rod 3 is connected to the bottom end of the fixed rod 12. The fixed rod 12 is rotatably connected to the inside of the main shaft 4. An outwardly protruding locking block 15 is integrally formed on the outer circumference of the fixed rod 12. A vertical groove 20 for the locking block 15 to move up and down is opened on the inner wall of the main shaft 4. An annular groove 14 is opened at the top of the vertical groove 20 inside the main shaft 4. The annular groove 14 allows the locking block 15, which has moved to the highest position, to rotate.

[0034] In this embodiment: when the fixed rod 12 moves upward, the fixed rod 12 drives the locking block 15 to move upward along the vertical groove 20 until the locking block 15 moves to the highest point. At this time, the locking block 15 enters the annular groove 14. The inner wall of the annular groove 14 has upward protruding limiting blocks distributed in the 90-degree direction to limit the rotation of the locking block 15 within the 90-degree range.

[0035] At this point, by rotating the handwheel 11, the handwheel 11 drives the fixed rod 12 to rotate, and the fixed rod 12 drives the locking block 15 to rotate within a 90-degree range, thereby opening and closing the valve plate 2. At the same time, the fixed rod 12 drives the sliding rod 13, and the sliding rod 13 drives the guide rod 3 to rotate through the square groove and the rectangular plate 18. The guide rod 3 can then drive the valve plate 2 to rotate, thus achieving manual adjustment when the electric control component malfunctions.

[0036] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
