第二章气动控制阀在气动系统中,气动控制阀是用来调节和控制压缩空气的压力、流量和方向的,可分为压力控制阀、流量控制阀和方向控制阀等。一、压力控制阀压力控制阀主要有减压阀、溢流阀和顺序阀。由空气压缩机将空气压缩、储存在气罐内的气压通常高于气动设备所需的压力,但压力波动较大,需用减压阀将其压力减到每台设备所需要的稳定压力。为了气动回路或储气罐安全,当压力超过允许压力值时,输入压力空气便自动向外
Chapter 2 Pneumatic Control Valve In pneumatic system, pneumatic control valve is used to regulate and control the pressure, flow and direction of compressed air. It can be divided into pressure control valve, flow control valve and direction control valve. First, the pressure control valve Pressure control valve are the main relief valve, relief valve and sequence valve. Compressed air is compressed by an air compressor. The air pressure stored in the air tank is usually higher than the pressure required by the pneumatic equipment. However, the pressure fluctuates greatly and the pressure reducing valve is required to reduce the pressure to the required steady pressure for each device. For pneumatic circuit or gas tank safety, when the pressure exceeds the allowable pressure value, the input pressure air will automatically outward
