SMC減壓閥的基本性能
SMC減壓閥的基本性能(1)
調壓范圍:它是指減壓閥輸出壓力P2的可調范圍,在此范圍內(nèi)要求達到規(guī)定的精度。調壓范圍主要與調壓彈簧的剛度有關。(2)
壓力特性:它是指流量g為定值時,因輸入壓力波動而引起輸出壓力波動的特性。輸出壓力波動越小,減壓閥的特性越好。輸出壓力必須低于輸入壓力—定值才基本上不隨輸入壓力變化而變化。(3)
流量特性:它是指輸入壓力—定時,輸出壓力隨輸出流量g的變化而變化的持性。當流量g發(fā)生變化時,輸出壓力的變化越小越好。一般輸出壓力越低,它隨輸出流量的變化波動就越小。減壓閥技術參數(shù):1、公稱壓力:1.0MPa、1.6MPa、2.5MPa2、殼體試驗壓力:P=1.5PN3.密封試驗壓力:P=1.1PN4、出口壓力:PN1.0MPa調節(jié)閥0.09~0.8MPaPN1.6MPa調節(jié)閥0.10~1.2MPaPN2.5MPa調節(jié)閥0.15~1.6MPa5、適用介質:水6、適用溫度:0℃~80℃
