What is Gate valves

图片
  What is Gate valves Gate valves  are widely used for all types of applications and are suitable for both above-ground and underground installation. Not least for underground installations it is paramount to choose the right type of valve to avoid high replacement costs. Gate valves are used to shut off the flow of liquids rather than for flow regulation. When fully open, the typical gate valve has no obstruction in the flow path, resulting in very low flow resistance. The size of the open flow path generally varies in a nonlinear manner as the gate is moved. This means that the flow rate does not change evenly with stem travel. Depending on the construction, a partially open gate can vibrate from the fluid flow Gate valves are mostly used with larger pipe diameters (from 2" to the largest pipelines) since they are less complex to construct than other types of valves in large sizes. Gate Valve Parts Main gate valve parts of a gate valve are: body, seat, gate, stem, bonnet and act

Why Does Stainless Steel Butterfly Valve Rust When In Use?

图片
Stainless steel butterfly valves will appear rusty when they are in use. Many friends don't know what caused it. Today the butterfly valve manufacturer will tell you about this problem. Let's learn about it with the   Butterfly Valve Supplier . Stainless steel butterfly valve will rust during use. Through metallographic analysis, dyeing test, heat treatment test, SEM and other tests, it is found that the key factor for material corrosion is the precipitation of carbides along the grain boundaries to form chromium-depleted areas, which causes the stainless steel butterfly valve to rust. Material CF8M stainless steel butterfly valve rusts during use. After austenitic stainless steel undergoes normal heat treatment, its structure should be austenite at room temperature, and its corrosion resistance is very good. Analyze the cause of butterfly valve corrosion. Butterfly Valve The stainless steel butterfly valve material is nickel-chromium austenitic stainless steel, which is usuall
