Description

Technical Field

[0001] This utility model relates to the field of valve technology, and in particular to a valve switch that does not require manual rotation. Background Technology

[0002] As a key component for controlling fluid transport, valves are widely used in many fields such as industrial production, municipal construction, and building water supply and drainage. For a long time, manual rotary valves have been the most widely used type of valve due to their simple structure and low cost. However, with the rapid development of various industries, traditional manual rotary valves have revealed many drawbacks in actual use, and the demand for new valve opening and closing mechanisms has become increasingly urgent.

[0003] Traditional valve switches mostly rely on manual rotation, such as using a handwheel to rotate the valve stem nut, which raises or lowers the valve stem to control its opening and closing. This method has significant shortcomings in some scenarios. For example, in space-constrained environments, manual rotation is difficult for operators; in emergency situations requiring rapid response, manual operation is slow and cannot achieve timely valve opening and closing; and for automated production processes that require frequent valve opening adjustments, manual operation is not only inefficient but also makes it difficult to guarantee adjustment accuracy. Therefore, we propose a valve switch that does not require manual rotation to solve this problem. Utility Model Content

[0004] The purpose of this invention is to provide a valve switch that does not require manual rotation, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A valve switch that does not require manual rotation includes: a pipe and a valve body. A valve body liner is provided on the inner wall of the pipe. The valve body is connected to the top outer side of the pipe. A threaded sleeve is rotatably installed inside the valve body. A valve stem screw is threadedly connected to the inside of the threaded sleeve. A worm gear is fixedly installed at the top of the threaded sleeve. A frame is fixedly installed on the outer side of the valve body. A rotating rod is rotatably installed inside the frame. A worm gear is fixedly installed on the outer side of the rotating rod. A valve disc is fixedly installed at the bottom of the valve stem screw. A connecting block is fixedly installed at the bottom of the valve disc. A diaphragm is fixedly installed at the bottom of the connecting block. A sensor is provided on one side of the frame.

[0007] Preferably, connecting flanges are fixedly installed on the outer sides of both ends of the pipe, and multiple bolt holes are opened inside the two sets of connecting flanges. The valve disc is slidably installed inside the valve body, the connecting block is slidably installed at the bottom of the valve body, and a limit plate is fixedly installed on the top of the screw.

[0008] Preferably, a drive motor is fixedly installed on one side of the frame, and one end of the rotating rod is fixedly installed on the output end of the drive motor.

[0009] Preferably, the worm gear and the worm are meshed, and both the worm gear and the worm are disposed within the frame.

[0010] Preferably, the top of the frame is provided with a sliding hole, and the valve stem screw is slidably installed in the sliding hole.

[0011] Preferably, the diaphragm is disposed inside the top of the pipeline, and the valve body is provided with multiple sets of limiting grooves inside, with the outer side of the valve disc being adapted to the multiple sets of limiting grooves.

[0012] In this utility model, a valve switch that does not require manual rotation is provided. Through the connecting flanges and bolt holes fixed on the outer sides of both ends of the pipeline, it is convenient to connect the pipeline to other equipment to build a complete fluid transportation system. The sensor monitors the pressure, flow rate and other parameters of the fluid in the pipeline in real time and transmits the data to the control system, thereby realizing precise control of the valve opening to meet the fluid transportation requirements under different working conditions. The valve body lining can prevent the valve body material from reacting chemically with the medium, prevent impurities from mixing into the medium, and ensure product quality.

[0013] This utility model features a reasonable structural design. A drive motor rotates the rotating rod and worm gear. Due to the meshing of the worm wheel and worm, the rotation of the worm gear drives the worm wheel and threaded sleeve to rotate. Under the constraint of the valve disc and the limiting groove, the threaded sleeve rotates, and through the threaded connection between the threaded sleeve and the valve stem screw, the valve stem screw drives the connecting block and diaphragm to move. When the diaphragm moves downwards, its extensibility causes it to seal the mounting hole, preventing the flow of fluid in the pipeline. This achieves the control of fluid flow interruption and conduction within the pipeline. Operators can easily open and close the valve simply by starting the drive motor, achieving precise control of the fluid flow rate in the pipeline. This meets the stringent flow control requirements of industrial production scenarios, greatly reducing labor intensity. It is particularly suitable for large valves or scenarios requiring frequent operation, meeting the needs of industrial automation and improving the overall intelligence level of the production system.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Reference Figure 1-3 A valve switch that does not require manual rotation includes: a pipe 1 and a valve body 5. A valve body liner 2 is provided on the inner wall of the pipe 1. The valve body 5 is connected to the top outer side of the pipe 1. A threaded sleeve 10 is rotatably installed inside the valve body 5. A valve stem screw 8 is threadedly connected inside the threaded sleeve 10. A worm gear 11 is fixedly installed on the top of the threaded sleeve 10. A frame 6 is fixedly installed on the outer side of the valve body 5. A rotating rod 18 is rotatably installed inside the frame 6. A worm gear 12 is fixedly installed on the outer side of the rotating rod 18. A valve disc 13 is fixedly installed at the bottom of the valve stem screw 8. A connecting block 14 is fixedly installed at the bottom of the valve disc 13. A diaphragm 15 is fixedly installed at the bottom of the connecting block 14. A sensor 19 is provided on one side of the frame 6.

[0020] In this embodiment, connecting flanges 3 are fixedly installed on both outer sides of the two ends of the pipe 1. Multiple bolt holes 4 are opened inside the two sets of connecting flanges 3. The valve disc 13 is slidably installed inside the valve body 5. The connecting block 14 is slidably installed at the bottom of the valve body 5. The top of the valve stem screw 8 is fixedly installed with a limiting plate 9, which greatly simplifies the connection process between the pipe 1 and other equipment or pipe 1.

[0021] In this embodiment, a drive motor 7 is fixedly installed on one side of the frame 6, and one end of the rotating rod 18 is fixedly installed on the output end of the drive motor 7, which reduces the workload of the operator and avoids operational errors caused by human factors.

[0022] In this embodiment, the worm gear 11 and the worm 12 mesh with each other, and both the worm gear 11 and the worm 12 are set inside the frame 6 to ensure that the valve is stably maintained at the set opening degree and to ensure the safe and stable operation of the pipeline 1 system.

[0023] In this embodiment, a sliding hole 17 is provided on the top of the frame 6, and the valve stem screw 8 is slidably installed in the sliding hole 17, which can ensure that the valve can be operated smoothly every time and ensure the stability of water supply.

[0024] In this embodiment, the diaphragm 15 is disposed inside the top of the pipe 1, and the valve body 5 is provided with multiple sets of limiting grooves 16 inside. The outer side of the valve disc 13 is adapted to the multiple sets of limiting grooves 16, thereby improving the stability and reliability of the entire production process.

[0025] In this embodiment, during use, the connecting flanges 3 and bolt holes 4 fixed on the outer sides of both ends of the pipe 1 facilitate the connection of the pipe 1 with other equipment to build a complete fluid transport system. The sensor 19 monitors the pressure, flow rate and other parameters of the fluid in the pipe 1 in real time and transmits the data to the control system. The valve body lining 2 can prevent the valve body material from reacting chemically with the medium, prevent impurities from mixing into the medium, and ensure product quality.

[0026] The drive motor 7 is started to drive the rotating rod 18 and the worm gear 12 to rotate. Since the worm wheel 11 meshes with the worm gear 12, the rotation of the worm gear 12 drives the worm wheel 11 and the threaded sleeve 10 to rotate. Then, under the restriction of the valve disc 13 and the limiting groove 16, when the threaded sleeve 10 rotates, it is connected to the valve stem screw 8 through the threaded connection between the threaded sleeve 10 and the valve stem screw 8. Thus, the valve stem screw 8 drives the connecting block 14 and the diaphragm 15 to move. The displacement of the valve stem screw 8 is guided by the sliding hole 17, and the displacement distance of the valve stem screw 8 is limited by the limiting plate 9. When the diaphragm 15 moves downward, it will block the mounting hole and prevent the flow of fluid in the pipeline 1, thereby realizing the cut-off and conduction control of the fluid in the pipeline 1.
