惊蛰古诗兔子的生活习性摘要：The valve includes both a bevelled plug, which cooperates with a at asmbly to throttle flow, and an annular, flat ating surface surrounding the plug, which ats against a corresponding annular, flat ating surface on the at asmbly when the valve is fully clod. The ating surfaces are made from a hardened material having a Brinell hardness greater than 500 so that the valve is capable of being ud to control the flow of high-temperature, high-pressure fluids, such as steam. The hardness of one ating surface is greater than that of the other to minimize galling and the ating surfaces are positioned away from the direct eroding effect of the high velocity flow during throttling, thereby maximizing valve life. The valve and at asmbly can be easily removed for renewal of the flat ating surfaces by relapping or the like.滑稽的读音
