Read： 267 Time：20months ago Source：Transform the World with Simplicity

With the continuous development of modern industry, flow control technology is more and more widely used, inspired people to design a variety of flow control devices. Among them, the throttling device is widely used in various fields because of its simple and easy to use, low cost, convenient installation and so on.

throttling device is generally composed of a throttle hole and a throttle valve. Its main function is to control the flow rate of the fluid medium through the throttle hole or the throttle valve, so as to achieve the purpose of flow control. The flow control principle of the throttling device mainly has the following methods:

1. The throttling control is realized by the flow limiting device, and the excessive flow of fluid can be hindered by setting holes or pipes with certain resistance, so as to realize the flow control function. This method is suitable for low pressure, small flow occasions, such as micro pumps.

2. through the throttle valve to control the throttle device, the use of regulating valve opening to change the flow rate of fluid inside the pipeline, flow, so as to achieve the purpose of flow control. This method is suitable for high pressure and large flow occasions.

3. By rotating the panel or baffle to change the flow area, so as to achieve flow control. The rotating panel or baffle controls the flow through manual control or automatic control, which is suitable for occasions with high requirements for flow control accuracy.

throttling device is widely used in industrial production, especially in petroleum, chemical industry, water treatment, automation, municipal facilities and other fields, plays an indispensable role. Specific applications are as follows:

1. In the petrochemical industry, throttling devices are used in fluid control, decompression and noise reduction, water injection in ore deposits, oil and gas separation and other fields.

2. In the treatment of domestic tap water and sewage, the use of throttling devices can reduce the loss and better control the flow, so as to achieve the purpose of energy reduction and emission reduction.

3. In the automatic control system, the throttling device is used for automatic control of buildings, ship helmsman, automobile air conditioning, etc.

In summary, the role of throttling devices in flow control cannot be ignored. With the improvement of technology, its structure is constantly evolving, its performance is constantly improving, and its application scenarios are becoming more and more extensive. I believe that through the introduction of this article, readers have a deeper understanding and grasp of the working principle and application of throttling devices.
