一个特殊设计的阀门用来调节热的高压氧气流体[最大工作压力和温度分别为4600psia(31.7MPa)和530°F(550K)]。这个阀门的基本设计是由一个螺线管驱动,并可在完全张开与部分张开的小孔位置间调节。尽管此阀门是根据氧气的应用而设计的,但它也能用在其它流体和气体的情况下。设计中要考虑的问题是需要减少阀门内壁 A specially designed valve is used to regulate the flow of hot, pressurized oxygen [maximum operating pressure and temperature of 4600 psia (31.7 MPa) and 530 ° F (550 k)] respectively. The basic design of the valve is driven by a solenoid that can be adjusted between fully open and partially open pinholes. Although this valve is designed for use with oxygen, it can also be used with other fluids and gases. The problem to be considered in the design is the need to reduce the inner wall of the valve
