Although linear float valves, regulating valves, and orifice plates are commonly used fluid control components, they are difficult to achieve high-precision flow control when used alone. Utility Model Content

[0008] Furthermore, the position of the oblique cut pipe opening is adapted to the position of the linear float valve.

[0009] Furthermore, the linear float valve is a mechanical float valve.

[0010] Furthermore, the regulating valve is an electric regulating valve or a pneumatic regulating valve.

[0011] Furthermore, the regulating valve has an adjustment accuracy of 0.05%-0.1%.

[0012] Furthermore, the throttling orifice plate is a porous throttling orifice plate.

[0013] Furthermore, the size and number of orifices on the orifice plate are adapted to the flow rate and the required system resistance.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] A throttling device for large magnetic levitation centrifugal heat pump units, such as Figure 1 , 2 As shown in Figure 3, the system includes a linear float valve 1, a regulating valve 2, and a throttling orifice plate 3; the linear float valve 1 is installed in the main pipe 5, which is connected to the inlet pipe 4; the regulating valve 2 and the throttling orifice plate 3 are installed in the bypass pipe 6, which is connected to the inlet pipe 4.

[0025] Specifically, the system comprises a linear float valve 1, a regulating valve 2, and a throttling orifice plate 3. The linear float valve 1 is located in the main pipe 5, which is connected to the inlet pipe 4. The regulating valve 2 and the throttling orifice plate 3 are located in the bypass pipe 6, which is also connected to the inlet pipe 4. The linear float valve 1 provides initial flow regulation in the main pipe 5, automatically adjusting according to changes in fluid level or pressure to achieve relatively coarse flow control. The regulating valve 2 performs more precise flow regulation in the bypass pipe 6, ensuring that the flow meets high-precision requirements. The throttling orifice plate 3, through its fixed orifice diameter, further refines flow control, helping to reduce flow fluctuations and improve system stability and reliability. The different control elements between the main pipe 5 and the bypass pipe 6 create a buffer zone, resulting in smoother flow changes and reduced impact on other components of the unit. This combination of coarse and fine adjustment makes the entire flow control system more flexible and efficient.

[0026] As a preferred embodiment of the above, such as Figure 3 As shown, the throttling orifice plate 3 is installed downstream of the regulating valve 2 in the bypass pipe 6.

[0027] Specifically, the orifice plate 3 is installed downstream of the regulating valve 2 in the bypass pipe 6 to further refine the flow control, achieving more precise and stable flow control and meeting the fine adjustment requirements of flow under different operating conditions. Through its throttling effect, a stable pressure difference can be generated downstream, which helps to stabilize the pressure of the entire system, maintain the efficient operation of the heat pump unit, and extend the equipment life.

[0028] As a preferred embodiment of the above, such as Figure 3 As shown, the inlet of the liquid inlet pipe 4 into the main pipe 5 is provided with a beveled inlet 41.

[0029] As a preferred embodiment of the above, such as Figure 3 As shown, the position of the oblique cut pipe opening 41 is adapted to the position of the linear float valve 1.

[0030] Specifically, the inlet of the liquid inlet pipe 4 into the main pipe 5 is equipped with a beveled inlet 41, the position of which is adapted to the position of the linear float valve 1. This structure guides the fluid to enter the main pipe 5 more smoothly, reducing eddies and impacts at the inlet, helping to reduce energy loss and improve the stability of fluid flow. This enhances the overall performance of the heat pump unit and allows for less energy loss, improving the energy efficiency ratio of the heat pump unit. Under the same input power, it can output more heat or cold energy, meeting higher energy efficiency requirements.

[0031] As a preferred embodiment of the above, such as Figure 3 As shown, the linear float valve 1 is a mechanical float valve.

[0032] As a preferred embodiment of the above, such as Figure 3 As shown, the regulating valve 2 is an electric regulating valve or a pneumatic regulating valve.

[0033] As a preferred embodiment of the above, such as Figure 1 As shown, the regulating valve 2 has an adjustment accuracy of 0.05%-0.1%.

[0034] Specifically, by using electric or pneumatic high-precision regulating valves, the regulation accuracy can reach 0.05%-0.1%, which exceeds the regulation accuracy of traditional throttling devices. This allows the heat pump unit to maintain a stable fluid flow under different operating conditions, thereby improving the unit's operating efficiency and stability.

[0035] As a preferred embodiment of the above, such as Figure 4 As shown, the orifice plate 3 is a porous orifice plate.

[0036] Specifically, by using a porous orifice plate 3, the throttling device can be customized according to specific flow requirements and system resistance, thus adapting to different operating conditions and needs and improving its versatility and flexibility.

[0037] As a preferred embodiment of the above, such as Figure 4 As shown, the size and number of orifices on the throttling orifice plate 3 are adapted to the flow rate and the required system resistance.

[0038] Specifically, the structure of the orifice plate 3 with the size and number of orifices adapted to the flow rate and required system resistance allows for precise control of the flow rate through the orifice plate by adjusting the size and number of orifices. This enables the orifice plate to be flexibly adjusted according to the flow requirements of the heat pump unit under different operating conditions, ensuring accurate flow matching and thus improving the system's operating efficiency and stability.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
