Air valve bodies play a vital role in various gas delivery and control systems. Understanding their working pressure range is essential for the correct selection and use of air valve bodies.
Generally speaking, the working pressure range of air valve bodies spans a wide range. Common air valve body working pressures can range from a few pascals to tens of megapascals.
For low-pressure air valve bodies, they are usually used in some occasions where pressure requirements are not high, such as civil gas systems, small laboratory equipment, etc. The working pressure of this type of air valve body is generally below several thousand pascals. Its design is relatively simple, focusing on the stability of sealing and flow control. The material selection usually uses relatively light and low-cost materials such as plastics and aluminum alloys. For example, in some domestic gas valves, the working pressure is usually around a few hundred pascals, mainly to ensure the safe delivery and control of gas, while facilitating user operation.
The working pressure range of medium-pressure air valve bodies is generally between several thousand pascals and several megapascals. This type of air valve body is widely used in gas delivery and control systems in industrial production. For example, in some chemical production processes, the gas pressure may be around several megapascals, and an air valve body that can withstand higher pressures is required. The design of the medium-pressure air valve body is more complex, and high-strength metal materials such as stainless steel and alloy steel are usually used to ensure its safety and reliability under higher pressures. At the same time, the medium-pressure air valve body also needs to have good sealing performance and flow regulation capabilities to meet the needs of different process flows.
The working pressure of the high-pressure air valve body is usually above tens of megapascals. This type of air valve body is mainly used in some special high-pressure gas applications, such as high-pressure gas storage and high-pressure gas delivery. The design and manufacturing requirements of the high-pressure air valve body are extremely high, and special materials and processes are required to ensure its safety and reliability under extremely high pressures. For example, in the valves of some high-pressure gas storage tanks, an air valve body that can withstand extremely high pressures is required, and strict safety protection devices are also required to prevent accidents.
In short, the working pressure range of the air valve body varies depending on the application. When selecting an air valve body, it is necessary to comprehensively consider factors such as specific working pressure requirements, gas properties, and use environment to ensure that a suitable air valve body is selected to ensure the safe and stable operation of the gas delivery and control system.
