Introduction to the characteristics of nuclear power valves

nuclear power valves are essentially the same as those used for HRB power generation. For high-pressure and large-diameter pipes, gate valves are mainly used for 10 years, butterfly valves are used for low-pressure and large-diameter pipes, and stop valves or angle stop valves are mostly used for small-diameter auxiliary pipes. As for check valves, safety valves and regulating valves, they are almost the same as those used in other fields. However, among the valves used in nuclear power, the valves used in the primary cooling system are absolutely not allowed to leak because the internal medium has radioactive energy. It is the valve production that requires high reliability to narrow the gap with foreign advanced technology; We will strengthen the research and development of materials such as hydrogen fuel cell materials, special functional fluorocarbon materials, copper foil for high-energy batteries, and high-efficiency solar spectrum selective absorption coatings. In terms of quality management, our products are also more stringent than other valves. In addition, the environment of the valve also has radioactive energy, so special materials and structures suitable for the atomic furnace must be considered. In addition to the punishment for molten metal and gas occasions, the technical standards for valves used in water cooling furnaces are detailed in ASME. This standard regards whether the friction of valve ④ rotating parts (bearings, pointers, etc.) passes through the gate as a pressure vessel, and expounds the technical standards to ensure its performance

the characteristics of nuclear power valves are as follows:

1 Require a high degree of reliability

2 Take measures to prevent external leakage

3 Its constituent materials are radioactive materials
