Working Principle Of Stainless Steel Stop Valve
After consulting a large amount of information, Stainless Globe Valve has a wide range of functions. The editor sorted out the following points:
Due to the small friction between the sealing surfaces during the opening and closing process, it is relatively durable, the opening height is not large, it is easy to manufacture and maintain, and it is not only suitable for medium and low pressures, but also for high pressures. The closing principle of the stop valve is to rely on the valve stem pressure to make the valve disc sealing surface and the valve seat sealing surface fit closely to prevent the flow of the medium. It can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive media. Therefore, this type of shut-off stop valve is very suitable for cutting off or regulating and throttling. Because the valve stem opening or closing stroke of this type of valve is relatively short, and it has a very reliable cutting function, and because the change of the valve seat opening is in direct proportion to the valve disc stroke, it is very suitable for regulating the flow.
The valve stem axis of the stop valve is perpendicular to the valve seat sealing surface. The valve stem opening or closing stroke is relatively short, and it has a very reliable cutting action, making this valve very suitable for cutting off or regulating and throttling the medium.
Once the valve disc of the stop valve is in the open state, there is no contact between its valve seat and valve disc sealing surface, and it has a very reliable cutting action, which makes this valve very suitable for cutting off or regulating and throttling the medium.
Once the stop valve is in the open state, there is no contact between its valve seat and valve disc sealing surface, so its sealing surface has less mechanical wear. Since the valve seat and valve disc of most stop valves are relatively easy to repair or replace the sealing elements without removing the entire valve from the pipeline, this is very suitable for occasions where the valve and pipeline are welded together. The flow direction of the medium changes when passing through this type of valve, so the flow resistance of the stop valve is higher than that of other valves.
