Power station globe valve, also known as power station regulating valve or Globe regulating valve, is an important valve widely used in the power industry, mainly used for accurate adjustment of the flow, temperature, pressure and liquid level of the medium. This valve has a variety of characteristics and advantages, suitable for high temperature and high pressure working environment, such as petrochemical industry, coal chemical industry, basic chemical industry, fine chemical industry, metallurgy, thermal power and other fields. The structural features of the power station globe valve include the pressure self-tightening sealing structure, which makes the sealing performance of the valve improve with the increase of pressure. Both ends of the valve body and branch pipe are usually welded, and the sealing surface of the valve disc and seat is made of materials with good wear resistance, high temperature resistance and abrasion resistance, such as cobalt-based cemented carbide plasma spray welding. In addition, the valve stem has been tempered and surface nitriding treatment, with good corrosion resistance and abrasion resistance.
