Pneumatic ultra-thin ball valve is a commonly used control valve, which has the characteristics of compact structure, rapid response and reliable sealing. This article will introduce the working principle and function of pneumatic ultra-thin ball valve, as well as the specifications and guidelines that need to be considered when selecting.
1. Working principle:
The pneumatic ultra-thin ball valve controls the rotation of the ball through the pneumatic actuator, so as to realize the switch control of the fluid. When the pneumatic actuator applies pressure, the sealing surface between the ball and the valve seat is completely closed or opened. The position of the sphere is controlled by adjusting the pressure of the air source, so as to realize the on-off and adjustment of the fluid.
2. Role:
It is mainly used to control the fluid in the pipeline and can be widely used in the control system of liquid and gas. It can realize fast switching operation and is suitable for occasions requiring frequent opening and closing. Due to the good sealing performance between the ball and the valve seat, it can maintain good sealing performance under high temperature, high pressure and corrosive medium environment.
3. Specifications:
Pneumatic ultra-thin ball valve specifications include caliber size, rated pressure, body material and connection methods. The caliber size is generally selected according to the flow requirements of the pipeline, and the common caliber ranges from a few millimeters to several meters. The rated pressure needs to meet the working pressure range of the pipeline system, and the valve body is usually made of materials with good corrosion resistance, such as stainless steel and copper alloy. The connection manner may be a flange connection, a threaded connection, a welded connection, or the like.
4. Selection Guide:
In the selection of pneumatic ultra-thin ball valve, need to consider the following factors:
Fluid medium: determine the required valve material and sealing performance to adapt to different liquids or gases.
Working pressure: Select the appropriate rated pressure according to the working pressure range of the system.
Temperature range: Ensure that the selected valve material and sealing material can withstand the medium within the expected temperature range.
Flow requirements: select the appropriate caliber size according to the flow requirements of the pipeline.
Control mode: select manual or automatic control pneumatic ultra-thin ball valve according to actual needs.
In short, pneumatic ultra-thin ball valves play an important role in industrial control systems. By understanding its principle, function, and considering the appropriate specifications and selection guidelines, you can choose a pneumatic ultra-thin ball valve that suits your needs, so as to achieve precise control of the fluid.
