The stainless steel check valve is a one-way valve device used to prevent liquid/gas backflow. It only allows things to flow forward and not back.
The structure of the stainless steel check valve is divided into three parts: valve body, valve disc and spring/gravity assist. Do you know the functions of these parts?
First of all, the valve body is equivalent to the outer shell of the valve, which is usually made of 304 and 316 stainless steel, which is corrosion-resistant and high-temperature resistant; the valve disc is equivalent to the baffle, which snaps shut when backflow occurs; the spring/gravity assist can help the valve disc close quickly to prevent water leakage.
These parts of the stainless steel check valve play a key role. Do you understand it now?
