Description

Technical Field

[0001] The utility model relates to the technical field of valve regulating equipment, in particular to an adaptive regulating structure for the outlet pressure of a valve. Background Technique

[0002] In modern industry, control valves are widely used in many industries such as petrochemical, coal chemical, pharmaceutical, and metal smelting. Control valves are mainly used to realize the regulation functions of parameters such as flow rate and pressure.

[0003] At present, the valves commonly used in daily life are generally shut-off valves, and the opening and closing of the valve body and the size of the flow rate are both realized by the rotation of the valve plate. Therefore, after turning the handle to open the valve, manual operation of the handle is still required to finely adjust the angle of the valve plate in order to control the outlet pressure to an appropriate size. If the outlet pressure is too small, the water output will not meet the demand; if the outlet pressure is too large, the flow rate will be too large and water resources will be wasted, making it inconvenient to use; thus, an adaptive regulating structure for the outlet pressure of a valve is proposed to solve the above problems. Content of the Utility Model

[0004] In order to solve the above technical problems, the utility model proposes an adaptive regulating structure for the outlet pressure of a valve. Through the set pressure gauge and regulating component, it can realize the adaptive regulation and control of the outlet water pressure within the set range according to the demand. When in use, there is no need to manually adjust the valve opening, and the valve can be used immediately after opening, which is convenient and fast.

[0005] The technical solution to achieve the purpose of the utility model is: an adaptive regulating structure for the outlet pressure of a valve, including an adjusting section pipeline, the left side of the adjusting section pipeline is fixedly connected with an inlet section pipeline, the right side of the adjusting section pipeline is fixedly connected with a monitoring section pipeline, a pressure gauge is arranged on the monitoring section pipeline, a support frame is fixedly connected to the surface of the adjusting section pipeline, a motor is arranged inside the support frame, an adjusting component is arranged inside the adjusting section pipeline, the adjusting component is connected to the motor, and the motor and the pressure gauge are electrically connected through an external control device.

[0006] In some embodiments, the adjusting component includes a multi-stage adjusting pipe fixedly connected to the inner wall of the adjusting section pipeline, a fixing plate is fixedly connected to the inner wall of the multi-stage adjusting pipe, a smooth rod is fixedly connected to one side of the fixing plate, a stop plate is fixedly connected to the inner wall of the adjusting section pipeline, and the end of the smooth rod away from the fixing plate is fixedly connected to one side of the stop plate.

[0007] In some embodiments, the adjusting assembly further includes a transmission rod rotatably connected to the inner wall of the multi-stage adjusting pipe. A main transmission bevel gear is fixedly connected to the surface of the transmission rod. A secondary transmission bevel gear is rotatably connected to one side of the fixing plate. The main transmission bevel gear meshes with the secondary transmission bevel gear. A driving bevel gear set is arranged at the top end of the transmission rod, and the driving bevel gear set is connected to the motor output shaft.

[0008] In some embodiments, the adjusting assembly further includes an adjusting threaded rod coaxially fixed to the secondary transmission bevel gear. An adjusting plate is threadedly connected to the surface of the adjusting threaded rod, and the adjusting plate is slidably connected to the optical rod.

[0009] In some embodiments, a booster pump is fixedly connected to the upper surface of the support frame. A water inlet pipe is fixedly connected to the water inlet of the booster pump. The water inlet pipe communicates with the inlet section of the pipeline. A water outlet pipe is fixedly connected to the water outlet of the booster pump. The water outlet pipe communicates with the monitoring section of the pipeline. The booster pump is electrically connected to an external control device.

[0010] Compared with the prior art, the remarkable advantages of the present utility model are:

[0011] In the present utility model, through the provided adjusting assembly and booster pump, through the monitoring and regulation of the pressure gauge and the control system, during use, the pressure gauge is used to monitor the pressure at the outlet in real time. When the pressure is too high, at this time, it is necessary to increase the water flow to relieve the pressure. The pressure gauge reading is fed back to the control system, driving the motor to rotate. The rotation of the motor drives the driving bevel gear set to rotate, causing the transmission rod to rotate. The rotation of the transmission rod causes the main transmission bevel gear to rotate, driving the secondary transmission bevel gear to rotate, driving the adjusting threaded rod to rotate. Under the action of the thread, the adjusting plate moves to the right. At this time, the empty space between the adjusting plate and the multi-stage adjusting pipe becomes larger and larger, and the water flow will become larger and larger, thereby reducing the pressure at the outlet. When the pressure is too low, similarly, the pressure gauge reading is fed back to the control system. In this case, the driving motor drives the adjusting threaded rod to reverse, causing the adjusting plate to move to the left, reducing the empty space between the adjusting plate and the multi-stage adjusting pipe, and reducing the flow rate to play a boosting role. When the water flow in the entire pipeline is very small, the pressure gauge reading is fed back to the control system, and the booster pump is started. The booster pump will directly form a new water path from the inlet end pipeline through the water inlet pipe and the water outlet pipe for boosting, which can ensure the normal circulation of the water path. It can realize the pressure adaptive regulation of the outlet water pressure within the set range according to the demand. During use, there is no need to manually adjust the valve opening. The valve can be used immediately, which is convenient and fast.

[0012] It solves the problem that the existing valves need to be manually adjusted according to the usage requirements when in use, which is inconvenient to use. BRIEF DESCRIPTION OF THE DRAWINGS

The adjustment component 7 is connected to the motor 6. The motor 6 is electrically connected to the pressure gauge 4 through an external control device. The selected motor 6 is an electrically controllable servo motor 6 to enhance the control and adaptive effect.

[0022] As Figure 2 and Figure 3 shown in the figure, in an embodiment, the adjustment component 7 includes a multi-stage adjustment pipe 701 fixedly connected to the inner wall of the adjustment section pipeline 1. The inner ring part of the multi-stage adjustment pipe 701 is stepped and gradually becomes wider along the water flow direction. A fixing plate 702 is fixedly connected to the inner wall of the multi-stage adjustment pipe 701. The fixing plate 702 is collinear with the vertical center line of the multi-stage adjustment pipe 701. A smooth rod 703 is fixedly connected to one side of the fixing plate 702. There are two smooth rods 703 distributed above and below the fixing plate 702. A stop plate 704 is fixedly connected to the inner wall of the adjustment section pipeline 1. The stop plate 704 has the same width as the fixing plate 702. One end of the smooth rod 703 away from the fixing plate 702 is fixedly connected to one side of the stop plate 704;

[0023] The adjustment component 7 further includes a transmission rod 705 rotatably connected to the inner wall of the multi-stage adjustment pipe 701. A main transmission bevel gear 706 is fixedly connected to the surface of the transmission rod 705. A secondary transmission bevel gear 707 is rotatably connected to one side of the fixing plate 702. The main transmission bevel gear 706 meshes with the secondary transmission bevel gear 707. The top end of the transmission rod 705 directly penetrates into the support frame 5. A driving bevel gear set 708 is provided at the top end of the transmission rod 705. The driving bevel gear set 708 is connected to the output shaft of the motor 6. The main gear in the driving bevel gear set 708 is coaxially fixed to the output end of the motor 6, and the secondary gear is fixedly connected to the top end of the transmission rod 705.

[0024] The adjusting assembly 7 further includes an adjusting threaded rod 709 coaxially fixed with the secondary driving bevel gear 707. One end of the adjusting threaded rod 709 penetrates through the fixing plate 702. Threaded holes adapted to the adjusting threaded rod 709 are formed in the adjusting threaded rod 709. An adjusting plate 710 is threadedly connected to the surface of the adjusting threaded rod 709. A sliding hole adapted to the smooth rod 703 is formed in the adjusting threaded rod 709. The adjusting plate 710 is slidably connected to the smooth rod 703.

[0025] A booster pump 8 is fixedly connected to the upper surface of the support frame 5. The booster pump 8 is an electrically controllable electrical booster pump 8 and is connected to the same control device as described above. The water inlet of the booster pump 8 is fixedly connected to a water inlet pipe 9. The water inlet pipe 9 is communicated with the water inlet section pipe 2. The water outlet of the booster pump 8 is fixedly connected to a water outlet pipe 10. The water outlet pipe 10 is communicated with the monitoring section pipe 3. The booster pump 8 is electrically connected to an external control device. The water inlet pipe 9 and the water inlet section pipe 2 and the water outlet pipe 10 and the monitoring section pipe 3 are all fixedly connected, and the connection position of the water inlet pipe 9 is before the pressure gauge 4.

[0026] The specific working method is as follows: When the valve outlet pressure adaptive adjustment structure is in use, after introducing water flow into the water inlet section pipe 2, maintain the fluidity of the entire structure so that the water flow can flow to the monitoring section pipe 3. Use the pressure gauge 4 to monitor the pressure at the outlet in real time. When the pressure is too high, at this time, it is necessary to increase the water flow to relieve the pressure. The reading of the pressure gauge 4 is fed back to the control system, driving the motor 6 to rotate. The rotation of the motor 6 drives the driving bevel gear set 708 to rotate, causing the transmission rod 705 to rotate. The rotation of the transmission rod 705 causes the main driving bevel gear 706 to rotate, driving the secondary driving bevel gear 707 to rotate, driving the adjusting threaded rod 709 to rotate. Under the action of the thread, the adjusting plate 710 moves to the right. At this time, the empty space between the adjusting plate 710 and the multi-stage adjusting pipe 701 becomes larger and larger, and the water flow will become larger and larger, thereby reducing the pressure at the outlet; when the pressure is too low, similarly, the reading of the pressure gauge 4 is fed back to the control system. In this case, the driving motor 6 drives the adjusting threaded rod 709 to reverse, causing the adjusting plate 710 to move to the left, reducing the empty space between the adjusting plate 710 and the multi-stage adjusting pipe 701, reducing the flow rate, and playing a boosting role. When the water flow in the entire pipeline is very small, the reading of the pressure gauge 4 is fed back to the control system, and the booster pump 8 is started. The booster pump 8 will directly form a new water path from the water inlet end pipeline through the water inlet pipe 9 and the water outlet pipe 10 for boosting, ensuring the normal flow of the water path.
