1、压力控制阀这类阀包括有溢流阀、顺序阀、平衡阀、减压阀、卸荷阀、背压阀、压力继电器等.打包机上使用了溢流阀、顺序阀、平衡阀、压力继电器等几种.压力控制阀的工作原理是依靠作用在阀芯上的液压力和弹簧力相平衡,以获得被控制流体的压力.(1)溢流阀一又称溢油阀、定压阀.安全阀亦属其范围.溢流阀在液压系统中的作用是限制该系统的最大压力不超过某一调定值.溢流阀的图形符号:
1. Pressure control valves These valves include relief valves, sequence valves, counterbalance valves, pressure reducing valves, unloading valves, back pressure valves, pressure relays, etc. The baler uses a relief valve, a sequencing valve, a balancing valve, Pressure relays, etc. The working principle of the pressure control valve is to rely on the role of the hydraulic pressure on the spool and the spring force balance, in order to obtain the pressure of the fluid being controlled (1) relief valve, also known as spill valve, set Pressure relief valve also belongs to the scope of relief valve in the hydraulic system in the role is to limit the maximum pressure of the system does not exceed a set value of the relief valve graphic symbols:
