Differences and differences between pressure reducing valve, safety valve, pressure stabilizing valve and pressure relief valve…

At first, Teflon in a narrow sense (Teflon: Chinese translation homophonic Te Iron F Fluorine Lon Dragon) was a trademark of DuPont, used for a series of fluoropolymer products based on polytetrafluoroethylene (PTFE). Polytetrafluoroethylene is a synthetic polymer compound formed by the polymerization of tetrafluoroethylene and is known as the "King of Plastics" for its excellent performance. Nowa…

1. Surface treatment: Clean, polish, degrease and other treatments on the valve surface to remove surface dirt and impurities, improve surface flatness and roughness, and facilitate the adhesion of subsequent coatings. 2. Coating protection: Apply a layer of corrosion-resistant coating, such as epoxy resin, polyurethane, etc., on the surface of the valve to form a protective film to block the …

Cast iron valves are usually made of high-quality gray cast iron or ductile iron, which have good mechanical properties, wear resistance and corrosion resistance. Cast iron valves have a long service life at normal temperature and pressure, and have low requirements for fluid media, and can adapt to a variety of environments and usage scenarios.…

The control valve is an important component of the industrial automation control system and is widely used in various industrial process controls. However, when the control valve is stuck or blocked, it will affect the normal operation of the control system and even cause equipment damage. Therefore, understanding the causes and treatment methods of the control valve getting stuck or blocked is of…

Application of Fluorine-lined Check Valve With the continuous development of industrial technology and the increasing requirements for environmental protection, the role of fluid control equipment in various industrial systems is becoming more and more important. Among them, fluorine-lined check valves, as a key fluid control device, are widely used in various fluid pipeline systems. 1. Working …

Fluorine-lined ball valve, as a key equipment widely used in many fields, is gaining more and more attention for its excellent performance and advantages. Its characteristics such as corrosion resistance, sealing performance, low fluid resistance, low friction coefficient, environmental protection and energy saving make it show outstanding performance in chemical, pharmaceutical, food, environment…

Pressure relief valve It is mainly used in situations where the pressure is too high. When the pressure is greater than the set value, the inner plate of the valve is pushed open to release the pressure in time. After the pressure is reduced, it returns to its original position. It is not much different from the safety valve. The pressure relief valve is mostly used for liquids, and the safety va…
