High temperature and high pressure ball valve is a type of valve that is resistant to high temperature and high pressure, and is wear-resistant The temperature can withstand up to 550 ° C The valve seat on both sides adopts the elastic force of the spring to tightly embrace the ball center and provide a sealing effect The sealing material is made of hard alloy, and the spherical surface is spray welded This hardness coefficient is relatively high The valve seat and valve body are sealed with graphite, so the temperature can withstand up to 550 ° C The sealing of high-temperature and high-pressure ball valves mainly uses metal sealing pairs, which have the advantage of being applicable to a wide temperature range, and the thermal expansion coefficients of various metals are not significantly different. As long as they are selected properly, they can achieve basic consistency, which is conducive to coordinating temperature difference deformation
