Description

Technical Field

[0001] This utility model relates to a valve, and more particularly to a multi-channel diversion valve with adjustable flow rate. Background Technology

[0002] Multi-channel diverter valves are core components in industrial pipeline systems used to distribute fluid flow. They are widely used in chemical, water supply, and energy industries. Through reasonable flow distribution, they can ensure that key parameters such as material supply, temperature control, and pressure balance in the production process reach the optimal state, thereby ensuring the stable operation and efficient output of the entire system.

[0003] However, traditional diverter valves mostly adopt a fixed diversion ratio design, which means that once installed, their flow distribution mode is difficult to adjust according to actual production needs. This greatly limits the system's ability to cope with changes. For example, when the production process needs to be adjusted or external conditions change, the existing valve configuration cannot meet the new requirements.

[0004] Therefore, it is necessary to design a multi-channel diversion valve with adjustable flow rate. Utility Model Content

[0005] In order to overcome the shortcomings of existing diversion valves that mostly adopt a fixed diversion ratio design, this utility model provides a multi-channel diversion valve with adjustable flow rate.

[0006] A flow-adjustable multi-channel diversion valve includes a cross-shaped pipe, a fixed box, a valve plate, a rotary table, a locking rod, a handle, a spring element, a first gear, a second gear, and a knob. The cross-shaped pipe is cross-shaped, and a fixed box is fixedly connected to the upper part of each branch pipe. Similarly, a valve plate is rotatably connected inside each branch pipe. A rotary table is rotatably connected inside each fixed box. The rotary table has multiple locking holes along its circumference, and each rotary table is connected to the valve plate on the same side. The left and right sides of the fixed box are slidably connected. Each lock bar has a locking rod that engages with a locking hole on the turntable on the same side. A handle connects two locking rods on the same side, and the handles are slidably connected to the fixed box. The upper part of the handles is exposed on the upper part of the fixed box. An elastic element connects each locking rod to the top of the fixed box. A first gear is fixedly connected to the upper part of the turntable. A second gear is rotatably connected to one side of the fixed box. The second gear meshes with the first gear on the same side. A knob is rotatably connected to the upper part of the fixed box. The knob is connected to the second gear on the same side.

[0007] Optionally, it also includes a filter screen, a scraper ring, a screw, and a motor. The filter screen is slidably connected inside the main cross-pipe. A scraper ring is fixed to the front side of the filter screen and is in close contact with the inner wall of the main pipe. A screw is rotatably connected to the upper part of the main pipe. The screw is threadedly connected to the filter screen. A motor is installed on the rear side of the upper part of the main pipe, and the motor output shaft is connected to the screw.

[0008] Optionally, it also includes directional markers and marking holes. The upper part of the fixed box is rotatably connected to the directional markers. The directional markers are fixed to the turntable on the same side. The two locking rods on the same side are slidably and rotatably connected to the directional markers. The upper part of the fixed box is provided with ring-shaped marking holes, and each marking hole corresponds to a single locking hole on the turntable below.

[0009] Optionally, it also includes a balancing orifice plate, which is fixed to the rear side of the main cross pipe. The balancing orifice plate is located behind the filter screen and in front of the junction of the branch pipes.

[0010] Optionally, it also includes a sealing ring, with sealing rings provided circumferentially on the valve plate, and the sealing rings fitting against the inner wall of the pipe.

[0011] Optionally, the balancing orifice plate is made of stainless steel.

[0012] Beneficial effects:

[0013] 1. This utility model allows for flexible flow distribution between different branch pipes by setting an independent control module in each branch pipe, meeting the needs of various application scenarios. At the same time, the combination of locking rod and locking hole can easily lock and unlock the turntable, ensuring the stability of the valve plate in the set position.

[0014] 2. This utility model provides intuitive operation instructions through the indicator rod and the marking hole, helping users to accurately set and identify the current flow distribution ratio. At the same time, the filter screen can effectively filter impurities in the fluid and prevent blockage, while the scraper ring can scrape off some of the deposits adhering to the inner wall of the pipe, improving the service life of the equipment.

Detailed Implementation

[0022] Example: A flow-adjustable multi-channel diversion valve, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the device includes a cross-shaped pipe 1, a fixed box 2, a valve plate 3, a turntable 4, a locking rod 5, a handle 6, an elastic element 7, a first gear 8, a second gear 9, and a knob 10. The cross-shaped pipe 1 is cross-shaped. Each branch pipe on the cross-shaped pipe 1 is fixedly connected to a fixed box 2 at its upper part. Similarly, each branch pipe is rotatably connected to a valve plate 3. Each fixed box 2 is rotatably connected to a turntable 4. The turntable 4 has multiple locking holes along its circumference, and each turntable 4 is connected to a valve plate 3 on the same side. Locking rods 5 are slidably connected to the left and right sides of the fixed box 2. Each locking rod 5 is connected to a valve plate 3 on the same side. The locking holes on the turntable 4 engage with the locking mechanism. A handle 6 is connected between the two locking rods 5 on the same side. The handles 6 are slidably connected to the fixed box 2, and the upper part of the handles 6 is exposed on the upper part of the fixed box 2. An elastic element 7, which is a spring, is connected between each locking rod 5 and the top of the fixed box 2. A first gear 8 is fixedly connected to the upper part of the turntable 4. A second gear 9 is rotatably connected to one side of the inside of the fixed box 2. The second gear 9 meshes with the first gear 8 on the same side. A knob 10 is rotatably connected to the upper part of the fixed box 2. The knob 10 is connected to the second gear 9 on the same side.

[0023] When the flow distribution ratio needs to be adjusted, the operator first needs to manually lift handle 6. At the same time, the elastic element 7 is compressed, causing the locking rod 5 to disengage from the locking hole on the turntable 4. At this time, the turntable 4 and the valve plate 3 connected to it are no longer mechanically locked and can rotate freely. The rotation angle of the valve plate 3 determines the flow rate of the fluid through the branch pipe. By controlling the rotation angle of the control knob 10, the operator can flexibly adjust the flow distribution ratio in each branch pipe to meet different application needs. When the required flow distribution ratio is reached, the operator needs to release handle 6. Due to the action of the elastic element 7, the locking rod 5 will automatically reset under the action of elastic force and re-insert into the target locking hole on the turntable 4, thereby locking the turntable 4 in a new position. In this way, the angle of the valve plate 3 is fixed, ensuring that the set flow distribution ratio will not change due to external interference.

[0024] like Figure 5 and Figure 6 As shown, it also includes a filter screen 11, a scraper ring 12, a screw 13, and a motor 14. The filter screen 11 is slidably connected inside the main pipe of the cross pipe 1. The scraper ring 12 is fixed to the front side of the filter screen 11 and is in close contact with the inner wall of the main pipe. The screw 13 is rotatably connected to the upper part of the main pipe and is threadedly connected to the filter screen 11. The motor 14 is installed on the rear side of the upper part of the main pipe by bolts. The output shaft of the motor 14 is connected to the screw 13.

[0025] The filter screen 11 can effectively intercept large particulate impurities in the fluid, ensuring the purity of the fluid and preventing these impurities from entering the branch pipe. The operator can also drive the screw 13 to rotate by starting the motor 14, so that the filter screen 11 moves forward along the pipe axis. During this process, the scraper ring 12 will scrape off the deposits on the inner wall of the pipe and carry the impurities away to the pipe opening, which is convenient for subsequent cleaning by personnel.

[0026] like Figure 2 , Figure 3 and Figure 4 As shown, it also includes a directional marker 102 and an indicator hole 103. The upper part of the fixed box 2 is rotatably connected to the directional marker 102. The directional marker 102 is fixed to the turntable 4 on the same side. The two locking rods 5 on the same side are slidably and rotatably connected to the directional marker 102. The upper part of the fixed box 2 is provided with a ring-shaped indicator hole 103. Each individual indicator hole 103 corresponds to a single card hole on the turntable 4 below.

[0027] The marking holes 103 serve as scale markers and are distributed on the top of the fixed box 2, forming a complete circular scale. This allows users to quickly understand the current flow distribution ratio in the pipeline simply by observing the marking holes 103 pointed to by the pointer rod 102 after turning the knob 10, without opening the fixed box 2.

[0028] like Figure 5 and Figure 6 As shown, it also includes a balance orifice plate 15. The balance orifice plate 15 is fixedly connected to the rear side of the main pipe inside the cross pipe 1. The balance orifice plate 15 is made of stainless steel. Stainless steel has high mechanical strength, is easy to weld and precision drill, and is also cost-effective. The balance orifice plate 15 is located behind the filter screen 11 and in front of the junction of the branch pipes.

[0029] When performing multi-channel independent adjustment, a change in the opening of a certain flow channel will cause a sudden change in the pressure of the flow divider chamber, resulting in flow fluctuations in other channels ("flow grabbing" phenomenon). The valve core will vibrate due to the excessive pressure difference on both sides, accelerating the wear of the seals. The balance orifice plate 15 can reduce the uneven flow and valve core oscillation problems caused by pressure fluctuations in the flow divider.

[0030] like Figure 2 As shown, it also includes a sealing ring 101. The valve plate 3 is provided with a sealing ring 101 along the circumference. The sealing ring 101 fits against the inner wall of the pipe. The sealing ring 101 can expand adaptively under fluid pressure, reduce the risk of leakage, and ensure the accuracy of flow regulation.
