SMC减压阀的基本性能
SMC减压阀的基本性能(1)
调压范围:它是指减压阀输出压力P2的可调范围,在此范围内要求达到规定的精度。调压范围主要与调压弹簧的刚度有关。(2)
压力特性:它是指流量g为定值时,因输入压力波动而引起输出压力波动的特性。输出压力波动越小,减压阀的特性越好。输出压力必须低于输入压力—定值才基本上不随输入压力变化而变化。(3)
流量特性:它是指输入压力—定时,输出压力随输出流量g的变化而变化的持性。当流量g发生变化时,输出压力的变化越小越好。一般输出压力越低,它随输出流量的变化波动就越小。减压阀技术参数:1、公称压力:1.0MPa、1.6MPa、2.5MPa2、壳体试验压力:P=1.5PN3.密封试验压力:P=1.1PN4、出口压力:PN1.0MPa调节阀0.09~0.8MPaPN1.6MPa调节阀0.10~1.2MPaPN2.5MPa调节阀0.15~1.6MPa5、适用介质:水6、适用温度:0℃~80℃
