[0001] The utility model relates to the technical field of valves, in particular to a manual-automatic inlet valve. Background Art

[0002] Imported valves are devices used to control the direction, pressure, and flow of fluids in fluid systems, enabling or stopping the flow of media (liquids, gases, powders) within piping and equipment. They can be categorized in various ways. The following are some common classifications and specific valve types: For example, shut-off valves, such as gate valves, globe valves, butterfly valves, ball valves, and plug valves, are primarily used to interrupt or connect the flow of media in pipelines. Different valve types are suitable for different media, pressure, and temperature conditions, so valve selection should be based on specific system requirements.

[0025] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0026] The specific implementation of the present invention is described in detail below with reference to specific embodiments.

[0027] See also Figures 1 to 5 The embodiment of the present utility model provides a manual-automatic inlet valve, which includes: a valve body 1.

[0028] In the embodiments of the present invention, please refer to Figures 1 to 5The valve body 1 is provided with a mounting frame 2, and the mounting frame 2 is provided with a control component 3 for driving the valve body 1; the control component 3 includes a linkage rod 31 and a driving rod 32, the linkage rod 31 and the driving rod 32 are respectively mounted in the mounting frame 2 for vertical and horizontal rotation, and a fixedly connected worm 321 is sleeved on the outer wall of the driving rod 32, and a fixedly connected worm gear 311 is sleeved on the outer wall of the linkage rod 31, the worm 321 is meshed with the worm gear 311, and the bottom end of the linkage rod 31 is fixedly connected to the top of the valve stem 11 in the valve body 1 by bolts; the control component 3 also includes a sliding frame 33, the sliding frame 33 is provided with two and symmetrically distributed on both sides of the interior of the mounting frame 2, and a rotatable rotating rod 333 is provided under the sliding frames 33 on both sides, and a driving motor 336 is fixedly installed on the end of the rotating rod 333 on one side, and a driving motor 336 is fixedly installed on the other side. The end of 333 extends to the outside of the mounting frame 2 and is installed with a fixedly connected turntable 335. Both sides of the bottom of the sliding frame 33 are fixedly installed with symmetrically distributed electric push rods 331. The bottom ends of the electric push rods 331 on both sides of the bottom of the same sliding frame 33 are provided with a fixedly connected mounting plate 332. The inner wall of the mounting plate 332 is rotatably connected to the corresponding rotating rod 333, and the outer wall of the mounting plate 332 is fixedly connected to the corresponding driving motor 336. Both sides of the outer wall of the driving rod 32 and the outer walls of the rotating rods 333 on both sides are sleeved with fixedly connected pulleys 35, and a transmission belt 36 is sleeved between the corresponding pulleys 35. Threaded adjustment screws 34 are inserted on both sides of the inside of the top cover 21. The adjusting screw 34 is rotatably connected to the top of the corresponding sliding frame 33, and the outer wall of the support rod in the sliding frame 33 is slidably connected to the inner wall of the top cover 21.

[0029] It should be noted that: through the setting of the electric push rod 331, when the staff needs to perform remote operation, the electric push rods 331 on both sides can be controlled to extend and retract respectively, thereby driving the belt 36 and the pulley 35 at the corresponding position to be tightly connected or loosely connected. When the application environment is affected by power outages and other factors and manual operation of the device is required, the adjusting screw 34 can be controlled to rotate, so that the sliding frames 33 on both sides are respectively moved up and down, thereby adjusting the tightness of the belt 36 and the pulley 35 at the corresponding position.

[0030] After the tension of the belt 36 is adjusted, the rotating rod 333 can be controlled to rotate by the required driving motor 336 or the rotary disk 335. The rotating rod 333 drives the driving rod 32 to rotate through the transmission between the tensioned belt 36 and the pulley 35. At this time, the driving rod 32 can drive the linkage rod 31 and the valve stem 11 to rotate through the engagement of the external worm 321 and the worm wheel 311, thereby realizing the opening and closing operation of the valve body 1. Therefore, when using the device, the driving state of the valve body 1 can be flexibly selected according to needs.

[0031] In this embodiment, when in use, a screw protection sleeve can be sleeved on the outside of the adjusting screw 34 to protect the outside of the adjusting screw 34, thereby reducing the dust particles in the outside air from being scattered on the threads of the adjusting screw 34 and causing the adjusting screw 34 to become stuck.

[0032] During use, when the tightly connected belt 36 rotates, the driving rod 32 can be driven to rotate. During this process, the rotating driving rod 32 will not drive the rotating rod 333 at the corresponding position to rotate through the transmission of the other side pulley 35 and the belt 36, thereby avoiding the mutual interference between the two driving modes.

[0033] In the embodiments of the present invention, please refer to Figures 1 to 5 , a top cover 21 is provided on the top of the mounting frame 2, and a fixedly connected scale ring 211 is provided on the top of the top cover 21. The top of the linkage rod 31 extends to the top of the top cover 21 and is installed with a fixedly connected comparison needle 5, and the inner wall of the top cover 21 is rotatably connected to the outer wall of the linkage rod 31, and a fixedly connected top shell 4 is sleeved on the outer side of the scale ring 211 at the top of the top cover 21. The inner top of the top shell 4 is inlaid with transparent glass 41, and a camera 42 is provided at the bottom of the transparent glass 41. A docking disk 12 is mounted on the outside of the valve body 1, and the docking disk 12 is located outside the valve stem 11. A plug rod 23 is inserted into the inside of the docking disk 12, and the plug rod 23 is fixedly connected to the docking disk 12 through a nut, and the top of the plug rod 23 is fixedly connected to the bottom of the mounting frame 2.

[0034] It should be noted that: through the setting of the camera 42 and the transparent glass 41, the camera 42 can take real-time photos of the comparison needle 5 and the scale ring 211 during the remote operation of the staff, and the transparent glass 41 makes it convenient for the staff to directly observe the status of the comparison needle 5 and the scale ring 211 during the manual operation, so that the staff can accurately control the opening and closing angles of the valve body 1.

[0035] In the embodiments of the present invention, please refer to Figures 1 to 5 A controller 22 is provided inside the mounting frame 2, and a slide groove 24 is provided on the side wall of the mounting frame 2. The inner wall of the slide groove 24 does not contact the outer wall of the rotating rod 333 with a turntable 335. A fixedly connected sealing piece 334 is sleeved on the outer wall of the rotating rod 333, and the outer wall of the sealing piece 334 is slidably connected to the outer wall of the mounting frame 2.

[0036] It should be noted that: through the setting of the slide groove 24, when the height of the rotating rod 333 with the turntable 335 needs to be adjusted, the slide groove 24 can enable the rotating rod 333 to smoothly pass through the installation frame 2 for vertical movement, and through the setting of the sealing sheet 334, the sealing sheet 334 located on the outside of the installation frame 2 can shield and protect the outside of the slide groove 24, thereby reducing the influence of external dust entering the installation frame 2 and the meshing movement of the worm wheel 311 and the worm 321 inside it.

[0037] The working principle of the manual-automatic inlet valve provided by the utility model is as follows:

[0038] When using this device, the device can be installed on the required pipeline first, and the controller 22 of the device can be electrically connected to the terminal control system. After the installation of the device is completed, the staff can send a signal to the controller 22 through the terminal control system to control the electric push rod 331 corresponding to the drive motor 336 to retract and the electric push rod 331 corresponding to the turntable 335 to retract;

[0039] At this time, the retracted electric push rod 331 can stretch and tighten the belt 36 through the corresponding pulley 35, so that the belt 36 can be tightly fitted with the corresponding pulley 35. Conversely, the belt 36 and the pulley 35 can be in a relaxed state, and then the drive motor 336 can be controlled to work;

[0040] The working driving motor 336 drives the rotating rod 333 to rotate, and the rotating rotating rod 333 drives the driving rod 32 to rotate through the transmission between the pulley 35 on the outer wall and the belt 36. The rotating driving rod 32 drives the worm 321 on the outer wall to rotate synchronously, thereby driving the linkage rod 31 and the valve stem 11 to rotate through the engagement of the worm 321 and the worm wheel 311, thereby realizing the opening and closing operation of the valve body 1;

[0041] During the rotation of the linkage rod 31, the staff can also accurately control the opening and closing angles of the valve body 1 by comparing the position between the needle 5 and the scale ring 211 captured by the camera 42. Moreover, due to the self-locking characteristics of the worm gear 311 and the worm 321, the valve stem 11 itself can be prevented from rotating randomly after the adjustment of the valve body 1 is completed.

[0042] On the contrary, when the application environment has a power outage or other conditions and manual operation of the device is required, the adjusting screw rods 34 on both sides can be controlled to rotate, so that it drives the sliding frame 33 equipped with the turntable 335 to move upward, and the sliding frame 33 on the other side moves downward, so that the belt 36 on the rotating rod 333 on one side of the turntable 335 is in close contact with the pulley 35 and is in a tensioned state, and the belt 36 on the other side is in a relaxed state, so that when the staff controls the rotating rod 333 to rotate through the turntable 335, manual operation of the valve body 1 can be achieved.

[0043] The circuits and controls involved in the present invention are all prior art and will not be described in detail here.

[0044] The above are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
