SMC气体减压阀,SMC减压阀现货特价
SMC气体减压阀的是由湿式阀用电磁铁，阀芯，传动柱塞，阀套，顶针杆，钢球，钢球座，复位弹簧等组成。阀芯与阀体为螺纹联接。传动柱塞一端连接电磁铁衔铁，另一端顶住钢球。因此无论是上端电磁铁的推力还是下端弹簧的作用力都使两钢球与顶针杆成连动关系。顶针杆两端与阀芯之间各有一段环形控制容腔，并分别与阀芯上的径向孔道连通。这是一种二位三通双球常闭式电磁阀。当电磁铁断电时，从P腔进入的压力油直接作用在先导阀的球座上，而复位弹簧的弹性力也同向作用在球座上，使先导阀下阀口关闭，上阀口打开，因而使压力油路与控制油路A阻断，控制油路与回油路T开通。
SMC气体减压阀的此外，在输入压力上升时，E室压力和F室瞬时压力也上升，膜片3在上下差压的作用下上移，关小稳压阀口12。由于节流作用加强，F室气压下降，始终保持节流孔13的前后压差恒定，故通过节流孔13的气体流量不变，使喷嘴挡板的灵敏度得到提高。当输入压力降低时，B室和H室的压力瞬时下降，膜片8连同挡板5由于受力平衡破坏而下移，喷嘴4与挡板5间间距减小，G室和D室压力上升，膜片3和15下移。膜片15下移使主阀口开度加大，使B室及H室气压回升，直到与调定压力平衡为止。而膜片3下移，使稳压口12开大，F室气压上升，始终保持恒节流孔13前后压差恒定。同理，当输出压力波动时，将与输入压力波动时得到同样的调节。
