    分配閥的作用:起到連接與分配的作用。各分管通過分配閥來與總管連接,這是連接作用;而且總管來源通過分配閥門分配到各去路管。

    控制油液流動方向時,液壓閥有液動和手動之分。液動換向閥:液動換向閥是利用控制油路的壓力油來改變閥芯位置的換向閥,操作較為方便,啟動力大。但是當液控油的流量較大時,換向沖擊也會比較大。因此,為了控制閥芯的移動速度,減小沖擊。通常在液控壓力油口前安裝單向節流裝置(阻尼調節器)。手動換向閥:手動換向閥是手動杠桿操作的方向控制閥,在液壓系統中起換向(改變液流方向)和開關(接通或切斷液流)作用。其操作簡便,工作可靠,無需電子。可以說安裝和使用非常簡單。缺點就是只能通過人手操作,自動化程度不高。

    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.
