The air valve body is a key component for controlling gas flow and plays a vital role in the gas delivery system. It achieves effective control of gas flow by accurately adjusting the opening degree of the valve.
First of all, the Air valve body usually consists of valve body, valve disc, valve seat and spring. As the main structure, the valve body supports the entire equipment and is connected to the gas pipeline. The valve disc is the core component that controls gas flow. It can move freely in the valve body and realizes gas switching and flow adjustment through contact and separation with the valve seat. The valve seat ensures that the valve disc has good air tightness when closed to prevent gas leakage. The spring plays an auxiliary role to help the valve disc return to its original position to ensure air tightness when the valve is closed.
When the gas flow needs to be adjusted, the Air valve body is controlled through the operating device. The operating device can be manual, electric or pneumatic, and the appropriate operating mode can be selected according to actual needs. The operating device drives the valve disc to move in the valve body, changing the gap between the valve disc and the valve seat, thereby changing the size of the gas flow channel. The larger the gap, the smoother the gas flow and the greater the flow rate; the smaller the gap, the gas flow is blocked and the flow rate decreases.
When controlling the gas flow, the Air valve body also needs to consider gas pressure, temperature and other parameters. The design of the valve disc needs to take into account the influence of these factors to ensure precise control under different working conditions. In addition, the Air valve body also needs to have high corrosion resistance, wear resistance and stability to ensure good performance during long-term use.
To sum up, the Air valve body achieves precise control of gas flow by adjusting the gap between the valve disc and the valve seat. It combines the optimization of structural design, material selection and operation methods to ensure stable and reliable gas flow control under complex and changeable working conditions.
