Description

Technical Field

[0001] This utility model relates to the field of flow regulating valve technology, and in particular to an integrated flow regulating valve. Background Technology

[0002] Flow regulating valves, also known as self-regulating flow control valves, flow balancing valves, or static balancing valves, are intuitive and easy-to-use flow regulation and control devices. In pipeline networks, flow regulating valves allow the flow rate to be set directly according to the design. Under the action of water, the valve can automatically eliminate the flow deviation caused by residual head and pressure fluctuations in the pipeline. Regardless of changes in system pressure, the set flow rate remains unchanged. These functions of the valve enable the pipeline network flow regulation to be completed in one step, turning network regulation work into simple flow distribution and effectively solving the hydraulic imbalance of the pipeline network.

[0003] Most existing flow control valves adjust the flow rate by directly rotating a handle to drive a gate. However, when adjusting the flow rate manually, operators cannot visually determine the number of rotations to adjust the flow rate, which can easily lead to excessive or insufficient flow rate adjustment, failing to meet actual flow rate requirements. Therefore, these valves are not easy to adjust intuitively and cannot meet customer needs.

[0004] Therefore, those skilled in the art have provided an integrated flow regulating valve to solve the problems mentioned in the background art. Utility Model Content

A regulating gate 3 is disposed between the two sealing gaskets 2. The outer surface of the regulating gate 3 is tightly fitted to the connection point of the sealing gaskets 2. A positioning cylinder 4 is embedded in the top of the valve body 1. The inner cavity of the positioning cylinder 4 is filled with sealing packing 5. A concave plate 6 is fixedly connected to the top of the valve body 1 and outside the positioning cylinder 4. A screw 7 is rotatably connected to the top of the inner cavity of the concave plate 6 via a bearing. A valve stem 8 is threadedly connected to the outer surface of the screw 7. The bottom of the valve stem 8 extends into the inner cavity of the valve body 1 and is fixedly connected to the connection point of the regulating gate 3. A servo motor 9 is fixedly installed on the top of the concave plate 6. The output end of the servo motor 9 passes through the concave plate 6 and is fixedly connected to the connection point of the screw 7. A connecting plate 10 is fixedly connected to the front of the valve stem 8. A concave indicator 11 is fixedly connected to the front. Scales 12, which cooperate with the concave indicator 11, are fixedly connected to both sides of the concave plate 6. Guide components 13 are provided on the top of both sides of the valve stem 8. Slide cylinders 14 are embedded in the top and bottom of the positioning cylinder 4. The inner surface of the slide cylinder 14 is slidably connected to the outer surface of the valve stem 8. A concave seat 15, which cooperates with the regulating gate 3, is fixedly connected to the bottom of the inner cavity of the valve body 1. The inner surface of the concave seat 15 is slidably connected to the outer surface of the regulating gate 3. Installation pipes 16 are connected to both sides of the valve body 1. The sealing packing 5 is tightly fitted to the valve stem 8 at the connection point. A protective cover 17 is fixedly connected to the top of the concave plate 6. The servo motor 9 is located inside the protective cover 17. Through holes, which cooperate with the installation pipes 16, are provided on one side of both the regulating gate 3 and the sealing gasket 2. The through holes are circular.

[0033] In this embodiment: By setting valve body 1, sealing gasket 2, adjusting gate 3, positioning cylinder 4, sealing packing 5, concave plate 6, screw 7, valve stem 8 and servo motor 9, the flow rate of valve body 1 can be easily adjusted.

[0034] Example 2:

[0035] Reference Figure 2 and Figure 3 The guide assembly 13 includes a guide plate 131. The outer surface of the guide plate 131 is fixedly connected to the valve stem 8. Guide grooves 132 that cooperate with the guide plate 131 are provided on both the left and right sides of the inner cavity of the concave plate 6.

[0037] The implementation principle of this utility model is as follows: In use, the operator connects the device to the external pipeline through the installation pipe 16. Then, when the flow rate needs to be adjusted, the operator powers on the servo motor 9 plug and starts the external controller of the servo motor 9. This causes the output end of the servo motor 9 to drive the screw 7 to rotate on the inner surface of the valve stem 8. This causes the valve stem 8 to drive the regulating gate 3 to move vertically on the inner surface of the sealing gaskets 2 on both sides. In addition, the valve stem 8 drives the connecting plate 10 and the concave indicator 11 to move vertically. When the valve stem 8 drives the regulating gate 3 to move vertically to the appropriate flow rate position, the valve stem 8 drives the connecting plate 10 and the concave indicator 11 to move vertically to the value corresponding to the scale 12. This allows the operator to intuitively view the flow rate adjustment of the device. The device is simple to operate and easy to adjust intuitively, thus meeting the needs of customers.

Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
