气动和液压系统一般分为气液源及处理系统,控制元器件,和执行元器件等组成,以上所说的各种阀都属于控制元器件。顾名思义,就是控制气液路系统各种介质或者参数。不外乎方向,流量,压力等等,以上这些阀也就是起这个作用。

先说方向控制阀,顾名思义就是控制流体的方向的,你所说的所说的换向阀和单向阀都属于方向控制阀。换向阀几乎是所有气液动元器件里种类最多,总量最大,相对来说也最受关注的一类元器件了。大家常常听到的什么两位两通,两位三通,三位五通等等都属于方向控制阀。

溢流阀属于压力控制阀,就是说压力达到或者超过某一个设定值后,气体从溢流口流出,从而保护系统的压力。

比例阀和伺服阀是从另外一个维度对阀进行分类。例如流量比例阀是对阀的流量进行自动的无级的调节,输入的电流信号与输出的气体流量成一定的比例关系。这与传统的阀差别很大。伺服阀用于伺服控制系统中,提高了系统的响应速度。这两种阀里又包含了压力控制阀和流量控制阀。比例阀与伺服阀与传统的电磁方向和压力控制阀相比价格高很多,一般的自动化行业较少用到。

Pneumatic and hydraulic systems are generally divided into gas-liquid sources and processing systems, control components, and execution components. The various valves mentioned above belong to control components. As the name suggests, it means controlling various media or parameters in the gas-liquid system. It's not just about direction, flow rate, pressure, and so on, and these valves just play this role.

 

First of all, the directional control valve, as the name suggests, controls the direction of the fluid. The directional control valve and one-way valve you mentioned belong to the directional control valve. The directional valve is almost the most diverse and total type of pneumatic and pneumatic components, and is relatively the most concerned type of component. What people often hear about two in two, two in three, three in five, and so on are all directional control valves.

The overflow valve belongs to the pressure control valve, which means that when the pressure reaches or exceeds a certain set value, gas flows out from the overflow port, thereby protecting the pressure of the system.

Proportional valves and servo valves are classified from another dimension. For example, a flow proportional valve automatically and steplessly adjusts the flow rate of the valve, and the input current signal is proportional to the output gas flow rate. This is very different from traditional valves. Servo valves are used in servo control systems to improve the system's response speed. These two types of valves also include pressure control valves and flow control valves. Proportional and servo valves are much more expensive than traditional electromagnetic directional and pressure control valves, and are less commonly used in the automation industry.
