Description

Technical Field

[0001] This utility model mainly relates to the technical field of pipeline valves, specifically a controllable valve for industrial equipment pipelines. Background Technology

[0002] Pipeline valves play a crucial role in pipeline systems. By opening or closing them, they can control the flow of media in the pipeline, enabling connection or disconnection, and can also regulate the flow rate and pressure of the media. Some special types of valves, such as throttle valves and pressure reducing valves, can change the flow rate or pressure of the media in the pipeline by adjusting the valve opening, thereby meeting different process requirements. However, existing functional valves are complex in structure and expensive. Considering the need for large-scale application in equipment requiring valves, this paper proposes a simple controllable valve for industrial equipment pipelines.

[0003] According to application number 202323444574.1, a pressure regulating control valve for a water supply pipeline includes a base plate and an inlet pipe. A sealing plug is movably sleeved inside the inlet pipe, and a sealing plate is fixedly connected to the top of the inlet pipe. A rotary motor is installed on the top of the sealing plate, and a threaded rod is fixedly connected to the output shaft of the rotary motor. A limit mechanism is provided on the top of the sealing plate.

[0004] The aforementioned document describes a method that uses a rotary motor to drive a threaded rod to rotate rapidly, causing the sealing plug to move up and down rapidly inside the inlet pipe. This achieves the effect of regulating the water flow rate inside the inlet pipe and realizes automatic flow rate adjustment. However, it lacks the function of relieving water pressure and can easily cause damage to pipe components due to pressure. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a controllable valve for industrial equipment pipelines to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A controllable valve for industrial equipment piping includes a bottom tube, two first curved tubes at the top ends of the bottom tube, a ball tube at the top of the first curved tube, two second curved tubes at the top of the two ball tubes, a top tube at the bottom ends of the bottom tubes connected to the top of the two second curved tubes, a mounting bracket at the middle of the bottom tube and the top tube, and two servo motors inside the mounting bracket.

[0008] Preferably, the first curved tube is bent at a parallel 90° angle and then bent at a vertical 90° angle.

[0009] Preferably, the second curved tube is bent vertically at 90° and then bent horizontally at 90°.

[0010] Preferably, the spherical tube includes a rolling ball disposed inside, a cylindrical groove disposed in the middle of the rolling ball to connect the first curved tube and the second curved tube, a connecting rod disposed at one end of the rolling ball and penetrating one end of the spherical tube, and a driven gear disposed at the other end of the connecting rod.

[0011] Preferably, the servo motor includes a drive gear with one end connected to the servo motor actuator and the other end rotatably connected to the top of the mounting bracket, and a drive gear sleeved in the middle of the drive rod and meshing with the driven gear.

[0012] Preferably, the bottom-mounted pipe includes a first connecting flange at the bottom and a first flow meter at one end of the outer wall.

[0013] Preferably, the top-mounted pipe includes a second connecting flange at the top and a second flow meter at one end of the outer wall.

[0014] In summary, this technical solution has the following main advantages:

[0015] This invention uses a servo motor and the meshing of drive and driven gears to drive a rolling ball to rotate inside a spherical tube, achieving precise control of the conduction area. It can adjust the water flow rate in different groups of the first and second curved tubes, thereby adjusting the water flow according to the set flow rate and pressure when different flow rates enter the pipeline. The gear reduction design prevents the problem of difficult-to-control conduction caused by excessive rotation of the rolling ball.

[0016] By using the repeated turning structure of the first and second curved pipes, as well as the design of the top-mounted pipe for diversion and the bottom-mounted pipe for merging, the flow velocity of the water is effectively reduced, the kinetic energy of the two water flows is dissipated, resulting in a decrease in flow velocity and pressure. This design allows for the adjustment of the water flow pressure in the pipeline by adjusting the flow rate ratio of different sets of the first and second curved pipes. Attached Figure Description

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0023] Example

[0024] Please refer to the attached document carefully. Figure 1 , 2 As shown in Figure 3, a controllable valve for industrial equipment pipelines includes a bottom pipe 10, two first curved pipes 11 located at the top ends of the bottom pipe 10, a ball-shaped pipe 12 located at the top of the first curved pipes 11, second curved pipes 13 located at the top of the two ball-shaped pipes 12, a top pipe 14 connected to the top of the two second curved pipes 13 at its bottom ends, a mounting bracket 15 located in the middle of the bottom pipe 10 and the top pipe 14, and two servo motors 16 located inside the mounting bracket 15. Each servo motor 16 includes a drive rod 161 with one end connected to the actuating end of the servo motor 16 and the other end rotatably connected to the top end inside the mounting bracket 15, and a drive gear 162 sleeved in the middle of the drive rod 161 and meshing with a driven gear 124. The bottom pipe 10 includes a first connecting flange 101 located at the bottom and a first pressure gauge 102 located at one end of the outer wall. The top pipe 14 includes a second connecting flange 141 located at the top and a second pressure gauge 142 located at one end of the outer wall.

[0025] As described above, during installation, the bottom pipe 10 is connected to the pipeline at a lower point via the first connecting flange 101, and the top pipe 14 is connected to the pipeline at a higher point via the second connecting flange 141. The first pressure gauge 102 monitors the flow velocity and pressure of the water inside the bottom pipe 10 in real time, and the second pressure gauge 142 monitors the flow velocity and pressure of the water inside the top pipe 14 in real time. When the flow velocity needs to be adjusted, the servo motor 16 is started, which drives the driven gear 124 to rotate via the drive gear 162 on the drive rod 161, and then drives the rolling gear 124 to rotate via the connecting rod 123. The ball 121 rotates inside the spherical tube 12, causing the cylindrical groove 122 to shift relative to the first curved tube 11 and the second curved tube 13, resulting in a change in the conduction area and thus a change in the flow rate. The number of teeth on the driven gear 124 should be much greater than the number of teeth on the driving gear 162 to achieve a gear reduction effect and prevent the rotation of the rolling ball 121 from being too large and making it difficult to control the flow rate. The two servo motors 16 can be adaptively started based on the difference between the first pressure gauge 102 and the second pressure gauge 142 through external control elements, thereby performing real-time regulation.

[0026] Please refer to the attached document carefully. Figure 1 , 2 As shown in Figure 4, the first curved tube 11 is bent at a parallel 90° angle and then at a vertical 90° angle; the second curved tube 13 is bent at a vertical 90° angle and then at a parallel 90° angle; the spherical tube 12 includes a rolling ball 121 disposed inside, a cylindrical groove 122 disposed in the middle of the rolling ball 121 to connect the first curved tube 11 and the second curved tube 13, a connecting rod 123 disposed at one end of the rolling ball 121 and penetrating one end of the spherical tube 12, and a driven gear 124 disposed at the other end of the connecting rod 123.

[0027] The aforementioned repeated turning structure of the first curved pipe 11 and the second curved pipe 13 effectively reduces the flow velocity of the water. The two second curved pipes 13 cause the top pipe 14 to split the flow, and then the two split water flows merge in the bottom pipe 10. Since the two water flows are in a reverse opposing state when they merge, the kinetic energy of the two water flows can be greatly dissipated, resulting in a decrease in flow velocity and pressure. Therefore, when it is necessary to adjust the pressure of the water flow in the pipeline, it can be controlled separately by two servo motors 16. By adjusting the effective flow guiding area inside the spherical pipe 12, the flow rate of the water in different sets of the first curved pipe 11 and the second curved pipe 13 can be adjusted respectively, thereby adjusting the flow ratio of the two water flows when they merge. Thus, the water flow can be adjusted according to the set flow velocity and pressure when entering different pipelines.

[0028] The above embodiments are only for illustrating the technical concept of this utility model and should not be construed as limiting the scope of protection of this utility model. Any modifications made to the technical solution based on the technical concept proposed by this utility model shall fall within the scope of protection of this utility model.
