Description

Technical Field

[0001] The invention belongs to the technical field of pipelines and conduits, and particularly relates to an adjustable flow pipeline. Background Art

[0002] In the field of fluid control, regulating pipeline flow has always been a critical technical issue. Traditional flow control methods often rely on mechanical structures such as valves and throttling devices, manually or electrically adjusting their openings to achieve flow control. However, these traditional methods have numerous limitations.

[0003] On the one hand, the limited adjustment accuracy of traditional valves and throttling devices makes it difficult to meet the demand for precise flow control in modern industry. In applications where precise flow regulation is required, such as chemical production, laboratory research, and precision manufacturing, traditional methods often fail to meet the required accuracy, affecting production efficiency and product quality.

[0004] On the other hand, traditional flow regulation methods have a slow response speed. In situations where rapid flow changes are required, such as automatic control systems and emergency response systems, the response speed of traditional methods may not meet actual needs, resulting in reduced system performance or even failure.

[0005] Furthermore, traditional flow control methods also present issues such as wear and clogging. Valves and throttling devices are subject to fluid erosion and corrosion over long periods of use, which can lead to surface wear, reduced sealing performance, and even clogging, compromising the stability and reliability of flow control.

[0006] In order to solve the above problems, an adjustable flow pipe is proposed to solve the problem of poor flow velocity controllability of the current pipe. Summary of the Invention

The guide channel is used to guide water flow, and the guide channel 1061 and the guide channel 2061 are communicated with each other. The connecting block 106 has a plurality of adjustment shafts 107 arranged in a circumferential array, and an axis hole 1071 is opened through the axis of the adjusting shaft 107. The plurality of adjustment shafts 107 are rotatably connected to the connecting block 106, and the plurality of adjustment shafts 107 are fixed to the plurality of adjustment gears 1 204; like Figure 6 and Figure 7 As shown, in some embodiments, the second connecting block 206 has a plurality of second adjusting shafts 207 arranged in a circumferential array. A second axial hole 2071 is formed through the axis of the second adjusting shaft 207. A plurality of guide holes 2072 are formed on the outer diameter of the second adjusting shaft 207. The guide holes 2072 communicate with the second axial hole 2071. The plurality of second adjusting shafts 207 are rotatably connected to the second connecting block 206. The plurality of second adjusting shafts 207 are fixed to the plurality of second adjusting gears 205. A second adjusting blade 208 is fixed to the outer diameter of the second adjusting shaft 207. like Figure 3 and Figure 4 As shown, in some embodiments, the connecting block 106 is rotatably connected to the connecting block 206; an adjusting blade 108 is fixed on the outer diameter of the adjusting shaft 107; A water hole 1081 is formed on the end surface of the regulating blade 108, and the water hole 1081, the shaft hole 1071 and the guide channel 1061 are connected; like Figure 1 、 Figure 5 and Figure 7As shown, in some embodiments, an inner adjusting ring 4 is rotatably connected to the inner part of the outer ring 1. The inner adjusting ring 4 is used to connect the device to the pipeline by connecting pipes at both ends. An overflow hole 401 is opened on the surface of the inner adjusting ring 4, and the 401 is used for the passage of water. The inner adjusting ring 4 is in contact with the surface of the adjusting blade 1 108 and the adjusting blade 2 208.

[0023] The inner adjustment ring 4 includes an inner adjustment ring 1 402 and an inner adjustment ring 2 403 . The inner adjustment ring 1 402 is penetrated by the adjustment shaft 107 , and the inner adjustment ring 2 403 is penetrated by the adjustment shaft 2 . The inner adjustment ring 1 402 and the inner adjustment ring 2 403 are rotatably connected.

[0024] like Figure 5 and Figure 7 As shown, in some embodiments, the inner adjustment ring 1 402 is rotatably connected to a valve 5, and the valve 5 is used to control the opening and closing of the pipeline. The inner adjustment ring 2 403 is fixedly connected to a pipe 6, and the pipe 6 is used to guide the water flow.

[0025] It should be noted that: the number of the first adjustment shaft 107 is the same as the number of the first adjustment gear 204, and the number of the second adjustment shaft 207 is the same as the number of the second adjustment gear 205; The first guide channel 1061 spirally extends toward the top of the second connection block 206 , and the second guide channel 2061 spirally extends toward the bottom of the first connection block 106 ; When the blade edges of the first regulating blade 108 and the second regulating blade 208 are in contact with each other, the gap between the adjacent second regulating shaft 207 and the first regulating shaft 107 is closed.

[0026] Working principle: When the water flow in the pipeline needs to be controlled to be minimum, the motor 3 is started, and the motor 3 drives the adjusting gear 2 205 to rotate, and the adjusting gear 2 205 drives the lower gear ring 203 and the middle gear ring 202 to rotate, and the middle gear ring 202 drives the adjusting gear 1 204 to rotate.

[0027] The rotation of the adjusting gear 1 204 and the adjusting gear 2 205 drives the adjusting shaft 1 107 and the adjusting shaft 2 207 to rotate, and the blade angle of the adjusting blade 1 108 is adjusted by the rotation of the adjusting shaft 107, and the blade angle of the adjusting blade 2 208 is adjusted by the rotation of the adjusting shaft 2 207. When the blade edges of the adjusting blade 108 and the adjusting blade 2 208 are about to contact, the gap between the adjusting shaft 2 207 and the adjusting shaft 1 107 is completely closed to block the passage of water.

[0028] Water flows into the connecting block 106 through the water hole 1081 , and the water in the connecting block 106 flows into the connecting block 2 206 through the diversion channel 1 1061 and the diversion channel 2 2061 and flows out through the diversion hole 2072 .

[0029] When it is necessary to gradually increase the water flow rate, the motor 3 is started to adjust the blade angles of the regulating blade 108 and the regulating blade 2 208. By adjusting the blade angles of the regulating blade 108 and the regulating blade 2 208, the size of the gap between the regulating shaft 107 and the regulating shaft 2 207 is changed, thereby changing the flow rate of water flowing through the device within a period of time. When the regulating blade 108 and the regulating blade 2 208 are perpendicular to the cross-section of the pipe, the flow rate reaches the maximum.

[0030] When it is necessary to further increase the flow rate of the water flow, by adjusting the motor 4, the motor shaft of the motor 4 is idling, and the adjusting blade 108 is affected by the water flow and automatically adjusts the angle and drives the connecting block 106, the inner adjusting ring 401 and the outer adjusting ring 101 to rotate. Since the guide channel 1061 in the connecting block 106 is a spiral structure, the rotation of the connecting block 106 provides speed for the water in the guide channel 1061 and flows out of the device through the guide channel 2 2061 and the guide hole 2072. In order to prevent the high-speed water flow from impacting and damaging the inner wall of the pipe 6, the water discharged from the overflow hole 401 slows down the speed of the water flow and changes the direction of the water flow when it contacts the high-coarse water flow, thereby achieving the effect of protecting the pipe 6.
