There are significant differences between vacuum valve and throttle valve in many aspects, mainly including working principle, scope of application, functional characteristics and so on.
Working principle
Vacuum valve: Vacuum valve is mainly used to control the gas flow in the vacuum system. By changing the position of the valve core in the valve body, it adjusts the opening and closing degree of the channel between the air inlet and the air outlet, so as to control the parameters of vacuum degree, flow rate and pressure. The working principle of the vacuum valve is based on the physical principle of gas flow in the vacuum state, and through the precise control of the valve core, the stability and efficiency of the vacuum system are ensured.
Throttle valve: A throttle valve is a valve used to regulate the flow of fluid in the pipeline. It works by changing the cross-sectional area of the channel to affect the flow of the fluid. When the fluid passes through the throttle valve, the velocity of the fluid increases due to the decrease in the cross section of the pipe, resulting in a pressure loss (also known as resistance). By adjusting the opening of the throttle valve, the volume or speed of the fluid passing through the pipe can be controlled.
Scope of application
Vacuum valve: Vacuum valve is widely used in the need for high vacuum environment, such as semiconductor manufacturing, vacuum metallurgy, vacuum drying and other fields. It can effectively control the gas flow and vacuum degree in the vacuum system, improve the stability and efficiency of the system.
Throttle valve: Throttle valve is widely used in a variety of occasions that need to regulate fluid flow. It applies not only to liquids, but also to gases. In industry, agriculture, aviation, ships and other fields, throttle valves play an important role. For example, in heating, air conditioning and refrigeration systems, throttle valves can be used to regulate the flow of hot and cold streams; In hydraulic systems, throttle valves can be used to regulate the flow of hydraulic oil.
Functional characteristics
Vacuum valve: The main function of the vacuum valve is to control the gas flow in the vacuum system, including adjusting the vacuum, flow and pressure and other parameters. It has the advantages of high sealing performance, flexible and simple operation, precise and stable control, etc.
Throttle valve: The main function of the throttle valve is to control the volume or speed of the fluid passing through the pipe. It can achieve precise control of fluid flow by adjusting the opening. However, the throttle valve will produce a certain amount of pressure loss and energy loss during the adjustment process, so it needs to pay attention to its impact on the system performance in practical applications.
Sum up
To sum up, there are significant differences between vacuum valves and throttle valves in terms of working principle, scope of application and functional characteristics. Vacuum valve is more suitable for the need for high vacuum environment, through the precise control of gas flow to achieve the adjustment of vacuum degree and other parameters; The throttle valve is more suitable for the need to adjust the fluid flow, by changing the size of the pipe section to achieve accurate control of the fluid flow. In practical applications, the appropriate valve type should be selected according to the specific needs.
