分配阀的作用：起到连接与分配的作用。各分管通过分配阀来与总管连接，这是连接作用；而且总管来源通过分配阀门分配到各去路管。

控制油液流动方向时，液压阀有液动和手动之分。液动换向阀：液动换向阀是利用控制油路的压力油来改变阀芯位置的换向阀，操作较为方便，启动力大。但是当液控油的流量较大时，换向冲击也会比较大。因此，为了控制阀芯的移动速度，减小冲击。通常在液控压力油口前安装单向节流装置（阻尼调节器）。手动换向阀：手动换向阀是手动杠杆操作的方向控制阀，在液压系统中起换向（改变液流方向）和开关（接通或切断液流）作用。其操作简便，工作可靠，无需电子。可以说安装和使用非常简单。缺点就是只能通过人手操作，自动化程度不高。

The function of the distribution valve is to connect and distribute. Each branch is connected to the main pipe through a distribution valve, which serves as a connecting function; Moreover, the source of the main pipeline is allocated to various distribution pipelines through distribution valves.

When controlling the direction of oil flow, hydraulic valves can be divided into hydraulic and manual. Hydraulic directional valve: Hydraulic directional valve is a directional valve that uses pressure oil in the control oil circuit to change the position of the valve core. It is easy to operate and has a large starting force. But when the flow rate of the hydraulic control oil is large, the reversing impact will also be relatively large. Therefore, in order to control the movement speed of the valve core and reduce impact. Usually, a one-way throttling device (damping regulator) is installed in front of the hydraulic control pressure oil port. Manual directional valve: A manual directional valve is a directional control valve operated by a manual lever, which plays a reversing (changing the direction of fluid flow) and switching (connecting or cutting off fluid flow) role in the hydraulic system. It is easy to operate, reliable in operation, and does not require electronics. It can be said that installation and use are very simple. The disadvantage is that it can only be operated manually and the degree of automation is not high.
